NEW RESEARCH SHOWS A NEED FOR LARGE COMPANIES TO TAKE CONTROL OF THEIR ENERGY USAGE

azprom Energy, the Manchesterbased specialist business gas and electricity supplier, recently conducted research among over 200 energy decision makers, working in large businesses, to better understand the challenges they face today. Set against a backdrop of rising expectations about corporate environmental performance and an increasing number of technological innovations that have impacted on the energy market, the results of the survey demonstrate that the challenges facing energy buyers for large businesses are centred around cost reduction and control. Of those surveyed, a quarter (26%) stated that the challenge that most concerns them is cost control and improving profitability, while 15% put sustainability and environmental pressures at the top of their priorities. These results signal a strong need for businesses to understand how they can reduce their on-going energy costs and become more environmentally astute whilst also improving the bottom line. Much of this knowledge can be acquired by commissioning an energy audit, enabling businesses to take control through scheduling energy usage and maintenance and implementing effective energy strategies. Responsible energy use is also a growing consideration for large businesses looking to add value to their

brand and is increasing in importance for those companies that have corporate social responsibility targets to meet. Over three quarters of respondents (87%) felt that the effective procurement, use and management of energy is the most important factor in meeting regulatory compliance targets under schemes such as the EU Emissions Trading System (EU ETS) and Streamlined Energy & Carbon Reporting (SERC). REMIT is also relevant to those buying and selling gas under a flexible purchasing agreement. These schemes, currently underpinned with concerns surrounding energy usage from the wider general public, mean procurement and management of energy will become a larger part of many companies’ overall business strategy. A company’s cost structures - the types and relative proportions of fixed and variable costs incurred by the business - can be profoundly influenced by their energy decisions. This is critical for large companies that hold a tighter budget. Almost all respondents (93%) with 100-499 employees felt that cost control and improving quality were most relevant to the effective procurement, use and management of energy. When considering possible risks to energy supply, there appear to be significant concerns that could be

alleviated through improved buyer insight into changes within the energy market. For example, 80% of respondents are concerned equally about price changes and the impact of energy restrictions. In the current economic and environmental climate this includes a range of factors such as the impact of ageing infrastructure and a rising population. Only half of those surveyed (54%) currently counter potential energy supply risks by improving supplier management and managing down consumption to reduce restrictions. Energy suppliers and consultants can offer buyers in-depth market intelligence and support with forecasting, gained largely through data science, to give them the opportunity to fully optimise their energy strategies and mitigate risk. In an era when we are all trying to be more environmentally conscious, large businesses have a responsibility to ensure that their energy usage is as economical as possible. By having greater understanding of consumption and better tools to enable them to closely monitor how this is changing over time, organisations can ensure they proactively address their corporate social responsibility in terms of energy reduction. www.gazprom-energy.co.uk.

Barclays backs University of Worcester to deliver its Green agenda

arclays has worked with the University of Worcester to agree a £2m Green Asset Finance fund, which will be used to deliver on the institution’s commitment to sustainability.

BAXI HEATING SELECTED TO PROVIDE RELIABLE TOTAL HEATING AND HOT WATER SOLUTIONS AT ‘FLEXICARE’ ACCOMMODATION SCHEMES

“G

ood partners are always crucial but particularly appreciated in times like these. Great work from all involved!” Anita Khan, Executive Director of Customer Services at settle. Social housing provider settle has selected Baxi Heating to provide reliable, energy efficient total heating and hot water solutions across two of their ‘flexicare’ schemes in Hertfordshire. Flexicare accommodation is especially for people aged 55+ with a care need and offers a flexible approach to the amount and type of care given to each resident. Ensuring reliable, efficient heating and hot water provision is vital in essential schemes like these as failure of the plant could result in building closure. As the landlord of the flexicare locations, settle has responsibility for all building maintenance and repairs – including the heating and hot water systems. Following a detailed mechanical and electrical services condition survey at Anderson House in Hitchin, settle chose to replace the dated, failing plant with Remeha Quinta Ace boilers and Andrews Water Heaters ECOflo units. Remeha and Andrews Water Heaters are both part of Baxi Heating. Reliability was a key requirement for settle’s Compliance Manager, Kevin Turner. “Our primary concern was to improve the reliability and energy efficiency of the heating

and hot water provision,” he explained. “At the same time, we were keen to standardise the equipment to ensure easier maintenance, servicing and operation of this service moving forward. The Remeha boilers met all the criteria as they are easy to install as well as maintain and, as our experience shows, deliver outstandingly reliable performance.” The fully condensing, direct-fired Andrews Water Heaters ECOflo units offer a cost-effective, energy efficient solution to meet the requirements at Anderson House. With a low NOx pre-mix power burner and an exceptional gross

efficiency of up to 98%, this water heater range will also help keep emissions and running costs to a minimum for settle. The installation at Anderson House is now complete and the new products are fully operational.

Logan Energy to open Central Belt’s first hydrogen refuelling station for vehicles

n Edinburgh-based hydrogen technology firm is announcing the opening of the first public hydrogen refuelling station (HRS) for vehicles in Scotland’s Central Belt. Offering the only refuelling stop between Aberdeen and Sheffield, some 360 miles apart, Logan Energy’s refuelling station will allow hydrogenelectric and dual-fuel vehicles to be refuelled to 350bar. With ambitious and legally binding 2050 Net Zero targets in place, now is the time to realise the potential of hydrogen in creating a greener, cleaner energy system. A report issued by the public-private partnership, Fuel Cells and Hydrogen Joint Undertaking, made conservative projections that fuel cell and hydrogen technologies will be able to generate 2,250 terawatt hours (TWh) of hydrogen in the European Union by 2050. In short, this would supply around a quarter of the EU’s total annual energy demand, and could fuel 42 million large cars, 1.7 million trucks, around a quarter of a million buses and more than 5,500 trains. With a strong belief in the hydrogen economy and its role in the future energy system, Logan Energy has financed this HRS itself and is offering this refuelling service to expand the potential of hydrogen in Scotland. It is also hoped that it will encourage people to consider hydrogen vehicles as viable green transport options. The HRS is based at Logan Energy’s Wallyford facility less than a mile off the A1, and will offer safe, supervised fuelling by trained personnel during working hours. Bill Ireland, CEO of Logan Energy, said: “While hydrogenpowered electric vehicles offer real reductions in carbon dioxide and other harmful emissions, the widespread uptake of these vehicles is restricted by the lack of investment in the deployment of refuelling stations.

“Refuelling is often offered as a package alongside the deployment of a fleet of hydrogen vehicles but without a proper refuelling infrastructure in Scotland, it is hard to get the buy in for investment in hydrogen vehicles. In turn, this lack of demand has made it harder than ever to create a case for building a proper refuelling infrastructure.” The opening of Logan Energy’s HRS comes hot on the heels of the UK Government’s £30 million funding support to several hydrogen projects across the UK tasked with investigating whether or not hydrogen could be used to slash emissions from sectors like industry and transport. Bill said: “While this recent UK Government investment is good news, we need more than just funding support if green hydrogen is to play its part in helping us reach Net Zero. We need sufficient Government support in the form of meaningful policy, backed up with effective “carrot and stick” legislation for both the expansion of hydrogen refuelling infrastructure and vehicles in Scotland. This needs to happen now as the deployment of the technology won’t happen overnight. With a Scottish ban on fossil fuel vehicle sales by 2032, and UK by 2035, petrol filling stations will start to see a decrease in revenue imminently and will need to look to the alternatives to survive. Our technology offers part of the solution.” Logan Energy is currently working with strategic partners to make its Wallyford base a ‘centre of excellence’ for hydrogen technology integration and safety. The opening of this refuelling station is one step towards achieving this goal. As part of this mission, Logan Energy will also be developing plans to produce green hydrogen on site, through electrolysis powered by solar power. www.loganenergy.com

SMARTER GRID SOLUTIONS LAUNCHES ANM STRATA 3.0 TO ACCELERATE THE NET-ZERO CARBON TRANSITION

he release of ANM Strata 3.0, Smarter Grid Solutions’ third generation DERMS, moves power companies a step closer to being able to monitor and manage tens of thousands of distributed energy resources (DER) simultaneously. At present, control systems can only handle tens to hundreds of devices, but the need to manage thousands is a near term prospect. ANM Strata 3.0 elevates the capabilities of power companies onto the next level, making it easier for them to manage more devices than ever before. The new version of the distributed energy resources management system (DERMS) will allow even more renewable energy devices to be connected to power grids, helping countries to meet their commitments under the Paris Agreement and ahead of the United Nations’ COP26 environmental summit in Glasgow in November. The release of the latest upgrade is a major step towards helping network providers to enable the net-zero carbon dioxide emission targets being set by a growing number of countries. As well as handling more DERs, this new product release is better placed to manage battery energy storage, which will be a key component in energy systems for storing the increasing amount of electricity generated by intermittent renewables, helping to better balance supply and demand and provide required flexibility to keep the grid stable. As with all of its software, SGSs’ new product boasts leading cybersecurity credentials and can generate and manage more data to support better DER and grid analytics programs. SGS will add new state-of-the-art security features as it encounters new use cases in order to meeet the challenge that comes from scaling to thousands of devices. Colin Gault, head of products at SGS, said: “ANM Strata 3.0 is a leap forward in network operators’ abilities to meet the challenges of reaching net-zero and tackling the climate emergency. “Renewable energy and energy storage are essential components to decarbonise our power networks and this is the software that will enable much larger numbers of energy devices to be integrated into the grid while maintaining stability. “With the latest version of our software, we have made some foundational changes to the underlying platform that support our product vision of mass scalability with no impact on availability, security or performance. “ANM Strata 3.0 also includes extensions to the existing DER dispatch application and more customisation of the user interface.” Users can now customise their own dashboards and share them with colleagues, as well as creating their own widgets. Other enhancements include: • asset scheduling with user defined validation rules specified; • the dispatch application now supports power factor dispatch; • improvements to the auto-configurations of merit order stacks in the configuration tool https://www.smartergridsolutions.com/

change I TOLD Behaviour is the key to YOU SO! climate change

Jes Rutter, Managing Director, JPR Solutions

have been banging the drum for years about how changing behaviour is key to climate change, and how the potential for energy and carbon savings from behaviour change is at least as much as from technological changes. I feel absolutely no pleasure in saying I told you so, I was right all along, but it’s true and the evidence is now plain for all to see and being widely reported. I have been working with ESTA, the Energy Services Technology Association, for the last 18 months to develop case studies of where very positive results have been achieved as a result of implementing energy behaviour programmes so that these can be used as evidence to encourage others. There are some very striking cases of great programmes that have worked. In one example, delivered by JRP, savings of 8.9% were made following a £30k behaviour change programme, the same savings as a £480k new factory LED lighting scheme for the same client. We have also been lobbying Government to acknowledge the role of behaviour change programmes and incentivise organisations to implement them. It has been a frustratingly slow journey with, I’m sorry to say, little to show for the effort. What we are all seeing right now is a real life case study on how the changes in our behaviours as a result of the Coronavirus pandemic are having really profound positive impacts on our world; reduced use of fossil fuels, reduction in greenhouse gas emissions, improved air quality, wildlife thriving, clean water, dolphins swimming in the Ganges and the canals of Venice, and the colours of our skies. Although Covid-19 is most likely the biggest global crisis since the Second World War, it is still dwarfed in the long term by climate change. The world will never be the same again after Covid-19 but what are we learning and what opportunities can we capitalise on?

There have been some painful and costly adjustments required by individuals and organisations to achieve the positive environmental impacts we are seeing. Sporting events, exhibitions, conferences, holidays, concerts, parties, social gatherings, shopping trips have all been cancelled. These cancellations have led to reduced travel, reduced production, less catering, less heating and lighting, less air conditioning and overall, less consumption etc, etc. In this mix, one significant element is transport which alone represents almost a quarter of Europe’s greenhouse gas emissions1 and is the main cause of air pollution in cities. Before Covid-19, the transport sector had not seen the same gradual decline in emissions as other sectors. This crisis has shown us that clearer skies and breathable air can be achieved very fast if concrete action is taken to reduce burning of fossil fuels but the global carbon emission reductions that the Covid-19 lockdowns are causing need to be repeated each and every year to prevent a 2 degree temperature rise. One thing is certain however, individuals and organisations will not voluntarily and willingly repeat the pain of the last 6 weeks in the pursuit of the long term climate change goal. Globally, concern about the environment and pollution is growing (see Figure 1) and according to a 2019 survey2 of more than 4,000 UK residents, 70% said they were concerned about climate change. In the past, however, survey results like these have not translated into real action. Too many people still buy unsustainable food, fly frequently and don’t take the meaningful daily actions 1 https://ec.europa.eu/clima/policies/ transport_en 2 The survey was conducted by the Department for Business, Energy & Industrial Strategy (BEIS) as part of its Energy and Climate Public Attitudes Tracker. https://www.statista. com/statistics/426733/united-kingdom-ukconcern-about-climate-change/

that help to reduce their environmental impact. Barriers such as ease, availability and current lifestyle trends mean that sustainable living has been more of an aspiration. In fact, Figure 2 shows clearly that individuals are looking for Government, businesses and civil society to resolve the climate change crisis. The UK Government has indeed made strong commitments to reducing greenhouse gases by passing laws to achieve Net Zero greenhouse gas emissions by 2050 and businesses are coming under ever increasing pressure to manage and reduce their emissions to meet this target. But we know that 50% of the opportunity to reduce energy consumption is being missed due to organisations focussing solely on technical opportunities. Behaviour change represents 50% of the global Net Zero opportunity but is rarely implemented. It is encouraging to see that many organisations now have Net Zero on their radar as a business objective. Some even claim to have achieved Net Zero. A major flaw in this is the way that organisations are currently being measured against Net Zero targets. How can it be right, for example, that the FIFA World Cup organisation can claim that they will deliver carbon-neutrality for the

OPINION 2022 World Cup in Qatar? FIFA and the State of Qatar have pledged to “measure, mitigate and offset” all emissions related to the design and construction of facilities and match-day events. But what about all those millions of air miles that will be racked up for spectators to go to games and the thousands of air-conditioned hotel rooms? Of course it could be claimed that FIFA have no control over ‘Scope 3’ emissions but this is a spurious argument as they can certainly influence the behaviour of the football fans by making different choices. For example, why hold such an event in a country where the average daytime temperatures exceed 50°C that necessitates all stadia to be air conditioned? When the world returns to a new normality it is likely that fewer people will be required to commute into central office locations3 with obvious implications for travel and transport and related emissions but none of this will save the human race by itself! The world’s focus currently is very much on surviving the next few months and none of us knows how our future will be re-shaped as a consequence of Covid-19. There will undoubtedly be unintended but nevertheless positive environmental impacts but, unless there are dramatic behaviour changes and significant lessons learned in the aftermath of this crisis, the journey towards climate disaster will continue. The world will never be the same again after Covid-19. The challenge is to make sure that the positive impacts are not lost or forgotten because we simply cannot go back to the destructive and carbon-emitting business as usual. So, with all this evidence of how people and their behaviour is crucial in tackling the climate crisis, can I stop banging my head against a wall? The harsh reality is that behaviour change at the level required to tackle the climate change crisis is hard and will not be voluntary. We need the Government to acknowledge the significant role of behaviour change in tackling climate change and start legislating and incentivising organisations and individuals. 3 https://www.theguardian.com/ technology/2020/mar/13/covid19-could-cause-permanent-shifttowards-home-working

CARBON NEUTRAL VS CARBON NEGATIVE: WHAT’S THE DIFFERENCE? Valpy Fitzgerald, Director of Green Markets at renewable energy provider, Opus Energy

s the conversation around sustainability develops past the point of the hypothetical, we now find ourselves at a decisive moment for the future of our planet. The UK Government has legislated to become carbon neutral by 2050, and has already begun working on policies that will enable that to happen – such as the proposed ban on the sale of new petrol and diesel vehicles. At the same time, businesses are becoming increasingly aware of the need to act now to reduce their total carbon output. According to the Carbon Trust, companies with fewer than 250 employees account for almost 20% of the UK’s total carbon emissions – meaning that their role in the fight against climate change is a vital one. With so many sustainability terms being used, it can be hard to know what’s relevant and what’s not. So, we’ve broken down the jargon around some of the most commonly used terms, and shared some advice on how businesses can become more ambitious in their sustainability targets.

CARBON NEUTRAL To achieve carbon neutrality means that your carbon emissions – that is, the carbon emitted by your day-to-day operations, such as manufacturing, travelling and so on - are effectively cancelled out. This is achieved by balancing your carbon emissions with techniques such as carbon offsetting – which involves calculating your carbon emissions and investing in schemes which are certified as removing a certain amount of carbon dioxide from the atmosphere. Depending on the partner you choose to work with, the schemes will vary, but tree planting is a common one. This is because trees naturally absorb carbon dioxide from the atmosphere, helping to reduce the volume of the greenhouse gas. Or carbon offsetting can be done by simply not emitting carbon at all – for example, choosing to cycle instead of drive. You might also hear people using the term net zero or zero carbon – these all mean the same thing. For example, if you used 100% renewable energy to power your business and used carbon offsetting to ensure your net operations and supply chain were carbon free, you could call yourself a “zero carbon” business.

CARBON NEGATIVE OR CLIMATE POSITIVE Carbon negative – also confusingly referred to as climate positive – goes one step further than carbon neutrality, aiming to remove more carbon from the atmosphere than you emit. For example, Drax – Opus Energy’s parent company – announced their goal to become carbon

negative by 2030. They’re doing this by using innovative technology to remove carbon from the air, meaning they will end up with less overall carbon emissions than they started with. Again, carbon negative has a number of other terms associated with it, but it is the ultimate goal for businesses of all sizes.

TAKING THE NEXT STEP It is undoubtedly a step in the right direction for businesses and organisations to commit to a carbon reduction plan, but it’s also important to look at the bigger picture and take the next step to reduce the overall emissions in the environment. While cutting down on air travel, using LED bulbs and switching to electric vehicles is to be applauded, industry leaders and governments now need to shift their focus to removing the amount of carbon that’s already in the atmosphere. This is because proactively working to ensure no more emissions are released won’t stop or slow down the impact that carbon dioxide and other greenhouses gases are having on the earth; not unless we couple it up with removing the existing emissions, and collectively work to become carbon negative. And this isn’t just a job for big business and corporations. As recycling has been adopted universally, going the extra mile to reduce the greenhouse gases in the environment needs to become a way of life for all businesses. Those looking to achieve carbon negative should first reduce their emissions by investing in energy-efficient technologies and energy storage, and potentially generating their own renewable energy. Choosing a 100% renewable energy supplier is also essential. Any remaining emissions can then be offset. While this may seem like a huge investment, particularly for smaller businesses, there are numerous benefits to be gained, from helping to save money and improving overall efficiency, to attracting and retaining top talent and improving customer loyalty. With the right negative emissions policy, companies can do much more, collectively removing millions of tonnes of emissions from the atmosphere each year. But there’s no one-size-fits all solution; every business will be at a different stage in their journey, so it’s important to focus on what’s right for you. www.opusenergy.com

OPINION

SAY YES TO SUSTAINABILITY: BUILDING THE PERFECT BUSINESS CASE Katie Burrows, Energy Services Solutions Manager at Haven Power

or many of us, sustainability is an everyday practice – a mindset we actively choose to cultivate for the good of the planet and those around us. We’re well familiar with the benefits, both on an individual and collective scale, and have taken measures to reduce our own carbon footprint. But bringing these values to the workplace and asking others to do same can often feel like a losing battle. When you’re the only person in the room that lives and breathes sustainability at work, it’s far from easy to educate your superiors about the benefits of greener practices - especially when making sustainable changes is often linked with pressure to spend more money. So, here are some top reasons that will help flesh out a robust business case to the decision makers of your organisation.

REPUTATION AND CUSTOMER LOYALTY If you’re part of a consumer-facing organisation, your customers are at the focus of everything you do. Whether the business is reviewing its manufacturing processes, customer service offering or management structure, the outcome of change is expected to benefit the consumers that invest their time and money in your service or product. But who says that customers care about how sustainable your practices are? Well, according to research by Unilever, a third of consumers now choose to buy from brands who they believe are doing social or environmental good. Whether that be reducing the amount of plastic packaging they use, recycling products or using a sustainable energy source, it all counts towards reducing your carbon footprint. The research also found that ‘sustainable brands grew 46% faster than the rest of the business and

delivered 70% of its turnover growth.’ It’s important to start with your business first, and implement the changes that will help to reduce your carbon footprint in the long run. However, it’s also becoming increasingly important for companies to look further along the supply chain. Pledging to improve sustainability has become a common trend among businesses all over the world in recent years, as consumers demand more visibility and are increasingly willing to do their own research into what processes have a negative impact on the environment. Take Sainsburys, for example, who recently pledged to invest in a greener future for the whole business. Not only does that include the obvious, like reducing the amount of plastic packaging that sits on their shelves, but it also includes ensuring that their suppliers are committed to reducing their carbon emissions.

have quickly become something that job seekers actively search for, with many now looking for a transparent employer that has strong ethical values. So, if the board wants to be able to attract top talent and have their pick of a wide bunch, their commitment to making sustainable changes could have a significant impact. Ultimately, existing workforces will be required to keep up with changes, while a young workforce with new skills will become invaluable due to rapid rates of innovation. As employers increasingly try to attract young talent, sustainability becomes more and more important. That’s because young people are very aware of their personal brand, including their efforts to live a more sustainable lifestyle, and where they work directly impacts this.

ATTRACTING AND RETAINING TALENT

As climate change has become a more pressing issue within our society over recent years, the pressure on businesses to commit to a greener strategy and actively reduce their carbon footprint has been mounting. The UK Government has committed to achieving net zero by 2050, while the target in Scotland is even more ambitious - 2045. It falls upon business and organisations within the UK to make rapid adjustments to their policies,

It’s not only your consumers that care about your carbon footprint – it’s your workforce too. A report by PwC found that over two thirds (65%) of people around the world want to work for a company with a powerful social conscience.

OPINION

processes and products in this time, and so starting to make changes as soon as possible is vital. Almost half of UK businesses have already put plans in place to reach net zero by 2050, with one in ten already there. So far, there has been a vast improvement in the amount of carbon emissions that are produced in the UK, particularly through electricity generation. A third (33.3%) of electricity generated in the UK in 2018 came from renewable sources, and whilst this was a vast improvement on previous years, this number needs to continue to rise to meet net zero. As a part of reaching net zero by 2050, the UK government has brought forward its ban on petrol, diesel and hybrid cars from 2040 to 2035. As a business, investing in electric vehicles is a huge investment, but it’s one that shouldn’t be immediately dismissed. There are a lot of things to be considered, but making the transition to electric vehicles will have both a significant impact on your carbon footprint and even save the business money in the long run. That’s because EV’s can help a business save around 20% on fuel costs and 30% on maintenance, with the added benefits of free road tax and a lack of congestion charges, too.

SAVING MONEY THROUGH ENERGY CONSUMPTION Whether it’s mostly used to power machinery, refrigerators or computers, energy often accounts for a significant percentage of an organisation’s operating costs. And, while the decarbonisation of the UK’s energy supply to achieve net zero is predicted to cost over £1 trillion, the board are likely to want to know exactly how this might impact the business’ profitability. According to our own research here at Haven Power, over a third (37%) of businesses think that it would be too costly to implement renewable energy, but we actually know that businesses can use renewable energy to save money. The easiest way to gain an understanding of how energy consumption can impact the business and its carbon footprint is to engage in a conversation with an energy supplier directly. An expert is the most likely person to know how your business specifically can reduce their energy consumption and therefore their carbon footprint. An expert might, for example, suggest joining Demand Side Response (DSR) programmes, which give you the opportunity to earn extra revenue by altering your energy consumption

patterns. Or, perhaps switching to a self-generated or stored electricity at peak times might be of benefit, as this is when power is at its most expensive. If you have the land and resources available, generating your own electricity using solar panels or a wind farm could be a great way to make some additional revenue. Organisations can get paid for generating their own electricity by setting up a renewable Purchase Power Agreement (PPA) with their energy supplier. It means your business receives the financial benefit of selling energy back to the grid, just without the administration. Committing to using greener practices as an organisation is not only a positive way to reduce your carbon footprint and reduce your negative impact on the planet, but there are also numerous benefits to the organisation from a business perspective. Offering a vast range of benefits, implementing more sustainable measures is an essential way to future-proof your organisation, enabling you to keep up with the competition and having a positive impact on your consumers. Ensuring that your business case for sustainability is backed by strong, relevant and relatable arguments is the key to helping the decision makers above you share your vision for change. www.havenpower.com

MONITORING & METERING

NOW IS THE TIME TO TAKE CONTROL OF YOUR ENERGY USAGE!

The corona virus crisis has impacted every aspect of our lives and, let’s be honest, the impact has been almost entirely negative, with many business premises currently standing unused and unstaffed. So, if you’re a facilities or operations manager, taking control of your company’s energy usage may well be the last thing on your mind. But, says Julian Grant of Chauvin Arnoux, this is actually a very important time to be ensuring that your business is not using and paying for energy it doesn’t need.

“W

hy would I bother looking at energy consumption when operations have stopped, and offices are virtually empty? Surely there is no energy usage to speak of in such circumstances?” Although this might at first sound like a valid thought, dig a little deeper and you will find that according to a survey carried out by British Gas, up to 46% of the electrical energy used by SMEs was consumed outside normal business hours. And, when a business is shut down because of the coronavirus, all day every day is “outside normal business hours”! With that startling 46% figure in mind, it’s clear that energy usage during the shutdown is something that’s well worth investigating. The key to gaining accurate and dependable information about your electrical energy usage is to use a portable energy logger (PEL). These versatile instruments can be easily installed at a distribution switchboard where they will monitor and record energy usage, along with a lot of other useful information. Some types can monitor multiple circuits simultaneously, which makes it easy for you to collect separate information for energy used by lighting, by HVAC systems, by machinery, by IT installations and so on. A PEL is an all-in-one instrument that measures a whole range of electrical parameters, such as voltage, frequency, current, real power, reactive power, harmonic levels and more. Crucially, the PEL doesn’t only measure these parameters, it also stores the results over a period of time that can range from a few minutes to months. This is essential, as some key issues, like equipment that is not needed during the shutdown but is still switched on and off automatically by a timer, can only be identified by looking at time-stamped energy usage records. Built with ease of use in mind, the best PELs have a large easy-to-read display and a clear logical menu system for selecting the parameters to be measured, stored and displayed. The ideal PEL should be supported by powerful yet intuitive software that can be used on a PC to analyse results. Further, in many applications the ability to monitor and analyse results in real time is valuable. A good PEL will be suitable for use on single-phase, split-phase and three-phase systems and will be designed so that it’s easy to install – ideally without the need to turn off the power. Another thing you should perhaps consider is the energy saving opportunities associated with

individual motors. Motors consume around 40% of all electricity used worldwide, and account for more than two-thirds of the electricity consumed by industry. Their performance degrades over time, and combined with advances in technology over the past few decades, replacing old motors can easily improve efficiency by 20% to 30%. The cost of running a motor for a year can be 10 times what it cost to buy it in the first place, and most replacement programmes will have a payback time of 1 to 3 years. The efficiency of your motor operation is therefore critically important if you’re aiming to lower your carbon footprint and reduce your energy bills. Start with your biggest motors first, because this is where you’re likely to be able to make the biggest savings. It will often be worth installing a PEL either temporarily or permanently, as this will provide a lot of useful information. The log will, for example, show exactly when the motor was running, which is important because a good way to waste energy is to leave the motor running when it’s not needed – during tea and lunch breaks, for example. Data from the PEL will also let you work out whether the motor is oversized. This is a significant issue because the efficiency of a standard induction motors falls as the load on it decreases and, below about 50% of its maximum loading, its efficiency will be decidedly poor. So, if the log reveals that the motor spends its whole life lightly loaded, it might pay you to fit a smaller replacement. Next, look closely at how the motor is controlled. If it has simple start-stop control – that is, it’s either running at full speed or stopped – you may well be able to make big savings by fitting a variable speed drive (VSD), especially if the motor is driving a fan or a pump. You may be thinking that with the present restrictions on travel, you won’t want to be visiting your business premises regularly to check on the data collected by a PEL. The good news is that if you choose a PEL from Chauvin Arnoux, you don’t have to. Once the PEL has been installed you

ENERGY MANAGER MAGAZINE • MAY 2020

can access it remotely, so that you can safely and conveniently monitor energy usage and all of the other parameters it records from the comfort and security of your own home – or, indeed, any other location where you have internet access. The remote access feature is easy to set up using the PEL Transfer software package which is available free-of-charge from the Chauvin Arnoux website. Buying a PEL can be a very profitable long-term investment and connecting to it remotely can give you valuable insights even if you can’t regularly visit the site. Hopefully this article has shown you how a PEL can help you to save money in the present challenging business climate but, if you have questions or would like more help and guidance on achieving energy savings during lockdown please don’t hesitate to contact Chauvin Arnoux. We’ll also be happy to explain how your PEL can continue to provide valuable benefits when life returns to something nearer to normality.

HOW TO COMPLY WITH UPDATED HEAT NETWORK REGULATIONS

Ian Allan, Head of Strategy for Switch2 Energy, offers guidance on the steps communal heating suppliers must take to comply with the updated Heat Network (Metering and Billing) Regulations (HNMBR).

he regulations, which stem from the EU Energy Efficiency Directive, are applicable to most sites that distribute thermal energy for heating, cooling or hot water from a central source to more than one end user, building or location. Legislation is enforced by the Office for Products & Safety Standards (OPSS). Regulations are currently being updated as part of the Heat Network Market Framework. One of the most significant areas of consultation is a requirement to retrofit final customer meters to non-metered homes, where a revised new feasibility tool shows that it is viable. Other proposals include extending provisions on meter accuracy, maintenance and billing. It is critical that heat suppliers comply with HNMBR – not just to avoid civil and criminal penalties – but to raise network performance and improve customer service. The regulations drive best practice in smart metering and billing. This pays off in terms of improved heat scheme efficiency, emissions reductions and better customer service. Real-time data from metering informs overall heat network efficiency and generates major performance improvements. As the UK accelerates the roll-out of heat networks across towns and cities, the regulations remain key to the difficult challenge of reducing CO2 emissions from space heating and are unlikely to be affected by Brexit.

THERE ARE 3 KEY REQUIREMENTS OF HNMBR 1. NOTIFICATION Heat suppliers must inform the OPSS about the location of any heat network or communal heating scheme - as well as its capacity and supply figures. Each building that forms part of the network must also be identified, along with the number of customers using it and details of the billing information they receive.. Registrations must be updated (using the updated notification template) every four years. Since most heat networks registered by the original notification deadline of December 2015, they should have re-notified by 31 December 2019, but it is believed that many of the UK’s 17,000 heat network operators failed to respond to this deadline. The OPSS has begun issuing formal warnings to these non-compliant heat networks.

2. METERING a. Point of entry meters It is mandatory for all communal heat schemes (with more than one

ENERGY MANAGER MAGAZINE • MAY 2020

building supplied with heat) to install point of entry meters, or bulk meters, which record the amount of heat delivered into a property from the plant room or energy centre.

b. Final customer meters It is also mandatory to install final customer meters on new builds and most buildings undergoing major renovation. If these meters are not feasible, the

MONITORING & METERING

viability of heat cost allocators must be considered. The meters require scheduled servicing alongside periodic recalibration of heat cost allocators. The requirement to fit final customer meters at existing non-metered properties is not yet compulsory, but this is likely to change soon. Consultation is currently underway as part of the Heat Network Market Framework, including proposals for a revised new feasibility tool, which will determine the viability of retrofitting final customer meters to non-metered homes. This will replace the original tool, which was suspended in 2015 and has now been re-designed. When the new tool is released, heat suppliers with non-metered networks will have to test the scheme to determine whether it is viable to install meters or heat cost allocators and then take any required corrective action. This test

must be repeated every four years and it is expected that all heat networks will need to be fully metered over time.

3. BILLING End customers must be billed using actual meter readings (rather than estimates) at least once a year. Those customers receiving bills electronically should, however, be invoiced quarterly. At a minimum, bills must contain current energy prices, details of total consumption (compared to the previous year, if applicable) and general information on how to improve energy efficiency. The legislation imposes duties on the heat supplier, but OPSS has issued guidance on how these responsibilities may be shared between billing managers and network managers or owners, subject to discussions on who is best placed to undertake these duties.

SIMPLIFYING COMPLIANCE Innovative new pay-as-you-go (PAYG) smart meters can simplify the compliance process and drive behavioural change by giving customers full visibility of how much energy they are using and how much it’s costing them. This leads to significant cost and carbon savings. In our experience, where we have installed smart metering and pay-as-you-go billing, heat usage has been reduced by up to 50%, compared to unmetered dwellings. OPSS has confirmed that PAYG systems are compliant if: • Billing information is available on the PAYG unit at any time • The PAYG unit has an approved in-home display feature • Meter readings are available on the unit • An annual billing statement is provided to customers Further information: www.switch2.co.uk

ENERGY MANAGEMENT

As one of the most varied sectors in the UK, there is no rulebook for energy management within the retail sector. However, there are certain steps all retail businesses can take to reduce their energy consumption, improving their overall energy efficiency and saving on energy costs.

mall changes can amount to a big difference. We has put together this quick guide to help you better manage your business’ energy usage.

LIGHTING

Retailers rely on bright lighting to entice customers, so it is no surprise that lighting often accounts for their biggest energy expense. Whilst the right lighting is essential for any retail business, there are ways in which you can lower your energy usage on lighting whilst still maintaining the same level of illumination: • Invest in low energy lighting – LED and similar lights can use up to 80% less electricity than conventional lightbulbs. • Use movement detectors – staff-only areas are often only occupied for a few hours each day, so this is a great place to save energy on lighting. • Regular maintenance – ensuring that bulbs and fittings are regularly cleaned, tested and replaced can reduce lighting levels by up to 30% a year. • Encourage staff to turn off lights when they are not needed.

IMSERV’S ENERGYSAVING GUIDE FOR RETAIL BUSINESSES HEATING Heating accounts for 29% of energy costs in commercial buildings, but you can be more energy-efficient without compromising the comfort of your customers and employees. • In warm weather, turn down the heating rather than opening the windows – turning down the temperature by just 1C could lead to an energy saving of 8%. • Reconsider your open door policy – limiting when doors are open can make a big impact on the amount of hot air escaping. • Consider installing automatic doors, which only open when necessary. • Set up timers – work around your store’s opening times, ensuring no energy is wasted when the majority of the store is empty.

REFRIGERATION Up to 20% of the energy used for refrigeration could be cut, with minimal or no cost. • Switch lighting in chillers off outside opening hours – the light generates heat, countering the cooling of the chiller. • Keep chiller doors shut – consider using reminders, such as stickers. • Maintain recommended temperature settings.

ENERGY MANAGEMENT It is essential to take energy

ENERGY MANAGER MAGAZINE • MAY 2020

management measures, in order to reduce energy costs. IMServ recommends taking the following steps in order to encourage better energy management throughout your business: • Invest in an energy data collection service: we offer both specialist Half-Hourly and Non-Half-Hourly data collection services. Data collection will help you develop a more accurate picture of your energy consumption, which is collected remotely, without requiring more costly manual meter reads. You can make a huge saving by receiving more accurate bills, based on actual consumption, rather than against estimate average profiles. • Involve your staff: with limited knowledge of the business’ energy costs, employees are unlikely to take an active role in helping reduce business energy consumption. As part of our Data Collection service, we will provide you with access to Energy DataVision (EDV) – an online portal with easy-tointerpret visualisations of your energy data. EDV can help your staff discover areas for energy • Make changes and measure the results: with a clear overview of your energy consumption data, giving you a starting point as a benchmark, you can monitor the impact your energy efficiency actions have on your energy usage – and cost savings! contactus@imserv.com https://imserv.com/edv/

ENERGY SECURITY

FOUR ESSENTIALS TO SPECIFYING RELIABLE, COST-EFFECTIVE PHYSICAL SECURITY FOR LONGTERM OPERATIONAL RESILIENCE The right choice of physical security will not only safeguard renewable energy installations from criminal attack and unauthorised entry, it can also add significant value to site safety, efficiency and service continuity. Terry Batten of Technocover outlines four key considerations. LOOK FOR LPCB CERTIFIED EQUIPMENT THAT WILL ADAPT TO EVOLVING NEEDS High security doors, enclosures, cabinets, access covers and associated physical protection are the backbone to operational continuity, often standing as the last line of defence shielding a critical asset or restricted area. But equipment must come with a robust assurance it will perform as required if subject to the assessed risk of criminal attack or infiltration by unauthorised personnel. LPCB certified security systems are becoming a staple across many sectors in managing the three Rs – resilience, risk and reputation. LPCB third party approval provides a rigorously tested standard of security performance for a full range of risk levels including terrorist. Testing is updated to Home Office edicts on security risk, and certification is underpinned by ongoing audits of production quality. LPCB products are widely approved by insurers, underlining their integrity in reducing commercial risk. As the basis for long-term resilience, partner with an LPCB specialist with the design expertise and product scope to expand and adapt your physical security as regulations and site operations evolve. Technocover’s leading capability includes modular, secure enclosures that can be scaled up and remodelled with panel extensions, retrofit roof systems, and new access gates - all within their LPCB certification. As the COVID-19 pandemic has reminded

us, energy resilience is crucial in maintaining power supply to hospitals, essential services and a locked-down population during a national emergency. A robust standard of physical security has a role to play not just during a crisis but in the day-to-day protection of storage and supply infrastructure associated with renewable energy systems.

IS THERE SCOPE TO CUSTOMISE TO ENHANCE OPERATIONAL SAFETY AND EFFICIENCY? A versatile choice of options and accessories will add significant functionality to security equipment, with benefits for safety management and site efficiency. Make sure that available locking and hardware are compatible with your adopted house security. Technocover can tailor its systems to existing security protocols by supplying the preferred access control system (eg key, card reader, fob, swipe) and hardware that supports CCTV and alarm networks while adhering to LPCB criteria. Other options, such as emergency panic bar exit, vision panels and internal override handles on security roof hatches, will help support the effective control of site access and emergency exit for authorised personnel. Access cover applications may require an assisted lift mechanism, safety stays and fall protection to comply with regulations on manual handling and falls from height.

ACHIEVE BEST VALUE SOLUTIONS TO COMPLEX NEEDS THROUGH ‘TOTAL SERVICE’ Careful design and planning will be necessary for more complex applications, for example, large access cover assemblies over plant, secure access for woodchip bunkers, or the integration of mesh enclosures and kiosks around existing assets. As an experienced design-to-install LPCB specialist of 27 years, Technocover works closely with clients on bespoke applications to identify and resolve operational, safety and installation issues and ‘build in’ maximum functionality within LPCB parameters. This reduces the risk of reactive maintenance and unplanned interventions, achieving best ‘whole life’ value from your security investment. Technocover’s Total Service ranges from technical innovations, such as solar power modules on cabinets and hydraulic sliding gates on security enclosures, to a full

construction service, from site preparation, concrete work and CDM compliant project management to life-time maintenance. Where site access is constrained or downtime is an issue, Technocover provides offsite assembly of its modular buildings with prefitted M&E services, including heaters, along with optional racking systems, aesthetic interior wall panels, and different floor finishes such as anti-slip. These can be craned in and connected within hours for minimal impact on operational continuity.

FINISHING TOUCHES – DOES IT MEET AESTHETIC AND DURABILITY CONSIDERATIONS? Premature ageing of operational assets and their vulnerability to the effects of climate change are of increasing concern. Security equipment that is not sufficiently ‘climate-proof’ will be a drain on maintenance budgets while risking service disruption if it succumbs to water, heat or wind damage from extreme weather. Technocover uses high quality steel, galvanising and paint processes to provide 25year service life. This assures a maintenancefree security system and extended time to replacement, to assist with reliable cost forecasting and resilience planning. Other features for weather resilience include domed, water-shedding access covers and roofs, raised thresholds on walk-in kiosks, and water sealing systems. Doors, kiosks and louvre windows can be made to blend with contemporary or traditional architecture, using features such as arch headers and colour finishes including wood effects. Technocover is a leading designer, manufacturer and installer of LPCB certificated UltraSecure physical security solutions, proven for critical infrastructure and government sites and backed by a Total Service design-to-install capability. www.technocover.co.uk Tel: 01938 555511

ENERGY SUPPLY

KEEPING BRITAIN’S LIGHTS ON:

MICROGRIDS: THE FUTURE OF UK ENERGY? Britain experienced its biggest blackout in more than a decade this summer due to two power plant outages, leaving almost a million homes across the country in the dark. Because of this, the energy watchdog and the government have raised concerns about the grid’s ability to cope with changing energy needs and demands. Here, Alan Binning, Regional Sales Manager at energy software developer, COPADATA, explains how microgrids could help.

microgrid is a small-scale power grid that can operate independently or collaboratively with other areas of the grid. Combining a range of generation sources with energy storage and intelligent load management, microgrids are hailed as the solution to providing reliable, economic and environmentally friendly power supply. Historically, microgrids were associated with remote power supply – providing electricity to developing nations or extremely rural locations. However, the potential applications of microgrids spread much further. According to a report by Navigant Research, there are 4,475 identified microgrid projects in proposal, planning and deployed stages, in a variety of different applications.

Don’t believe the hype? You should. The popularity of microgrids can be largely correlated with their potential to lower electricity prices for businesses. In fact, microgrids are estimated to save between 21 and 30 per cent on current energy costs, while reducing peak power requirements. This is particularly important for organisations that need a high level of energy reliability, such as data centres or hospitals. For these businesses, a microgrids ability to operate independently from the larger grid — sometimes referred to as island mode — is invaluable. Businesses owning their own generation assets can also benefit from improved energy security compared to being reliant on the larger grid. Known as demand side response, in companies attached to the national grid can be asked to reduce their energy consumption. This would not be a problem if the business is running on its own micro generation. Microgrids can empower the user, but what’s the benefit to the larger electricity grid? When the grid is in crisis, like Britain‘s summer blackout, microgrids can help to react to unexpected demand peaks. That said, Summer 2018 may have provided a better example. Following Croatia’s 109th minute goal during the World Cup semi-final, it is safe to hypothesise that many England fans may have immediately flicked on the kettle to drown their sorrows in a good old brew. Or, perhaps more plausibly, simultaneously fired up thousands

ENERGY MANAGER MAGAZINE • MAY 2020

of the nation’s pub cash registers. During this moment, the grid will suddenly experience a surge in power demand, but not necessarily a surge in power supply. If the supply isn’t available, that’s where microgrids can sell excess energy back to the grid. Sounds complicated, but microgrid software means it doesn’t have to be. zenon, COPA-DATA’s software platform, makes automated operation of microgrids easy. The local operator who is monitoring the microgrid would be able to provide excess energy during these periods of peak demand— balancing generation from intermittent renewable power sources with distributed, controllable generation and storage. Not to mention fulfilling England fans need for a little pick-me-up. With the growing favourability of renewable generation sources, microgrids offer a more controllable, reliable and highly flexible solution to Britain’s fluctuating energy problem. Those looking at microgrid projects could benefit by looking outside of the traditional distribution management solutions, at platforms like zenon, that can better scale to suit these applications. Enhancing grid resilience, microgrids can help the main energy grid recover from system outages, either indirectly, by sustaining services needed by restoration crews, or directly, by helping to re-energise the macrogrid. Either way, microgrids will be the future, helping to keep Britain’s lights on in a cost effective, environmentally friendly way. www.copadata.com.

COMPANIES THAT SWITCH WATER SUPPLIER CAN EXPECT SIGNIFICANT SAVINGS ON COSTS GOING FORWARD AND REBATES DUE TO HISTORICAL BILLING ERRORS

t is absolutely true companies that switch water supplier can expect to reduce their on going water and waste water bills and claim money back due to historical overcharges as £millions remains unclaimed and businesses continue to unknowingly pay their bills when in fact the charges may be incorrect. Whether your business has or hasn’t switched water supplier it makes no difference at the end of the day. If you did decide to switch water supplier and you are now supplied by a different water retail company there is no guarantee that your water bills are correct, far from it! The appointed water retail company who ever that may be, charges customers in accordance with the wholesale market data, it is not the fault of the water retailer, which from a customers perspective is difficult to understand but true. Says Graham Mann a water consultant who heads up H2O Building Services, one of the UK’s longest established water consultancies. “This is one particular area that does breed mistrust amongst many customers. “I hear this time and time again, and now since the water industry has deregulated allowing companies to switch water supplier the incorrect charging has become even more widespread. “In many cases the customer market data the water retailers are billing against is not accurate and therefore customers are not receiving the correct charges. “Customers are unknowingly accumulating substantial debts as they are also under billed and so if the customer is unaware of the under billing they will not be making any provision for a back charge. “Our water audit department is now dealing with increased cases of water retailers back charging customers as water wholesalers impose back charges on them to pass onto customers.

“Again customers should be aware, even some back charge bills are not correct as a customer back charge bill was reduced by 45 percent saving the client £22,000 on their bill and £19,000 on future bills going forwards. “This is just one of many, we are now seeing quite a trend in this activity but be warned not all back charged bills are correct!!” So what can customers do right now during these challenging economic times?” Here is some sound expert advice from Graham Mann. “Dealing firstly with a back charge bill, if a customer receives a bill for services that has been billed before, the customer has been charged for water and waste water services but has been undercharged in some areas, my advice in the first instance is commission a water industry expert and request a waste water audit and evaluation report. “I say this in all instances of historical back charging bills, a desktop water and waste water audit and evaluation report should be conducted and this will not cost the customer a fee, they are mostly simple and straight forward, however an expert option is always a wise move. “If the charges are correct, rarely do water retail companies discount back charges as by this time they have received and probably paid the wholesale charges.

“Prior to deregulation we were able to negotiate discounts of up to 50 percent on back charges as the water company was both the wholesaler and the retailer, one company, now if a retailer were to discount the amount would be a straight forward loss but always take expert advise as there are stringent regulated rules on back charging customers. “Our water bill validation team recently rejected 2 back charge claims due to the incorrect start dates and they are significant numbers.” If your business is seeking to reduce water and waste water bills through switching water supplier, historical water audits or experience historical water bill back charges, then contact the experts H2O Building Services: info@h2obuildingservices.co.uk you will be glad you did!

HEAT PUMPS

2020 CONSTRUCTION TRENDS: SMART FIFTH GENERATION DISTRICT HEATING Matthew Trewhella, Managing Director of Kensa Contracting

he UK Government recently committed to a 2050 net zero carbon target in an effort to limit the worst effects of global warming. With the introduction of a Future Homes Standard mandating the end of fossil-fuel heating systems in all new build homes from 2025, house-builders, planning, and building control are in a prime position to encourage low-carbon developments utilising eco-friendly building techniques and innovations in renewable technology to achieve our carbon ambitions.

LOWERING CARBON The Future Homes Standard, effectively the follow up to the “ban the gas boiler” announcement, sets out what we can expect from our buildings from 2025. And how we are going to get there is notably the “transitional arrangements” in the proposed Future Homes Standard, which could see an almost overnight ban on oil, LPG and electric as soon as mid 2020; under the Standard gas will get much harder and heat pumps many times easier to introduce into new-build homes. The proposed new SAP calculation is intended to allow assessment of the effects of the Future Homes Consultation proposed options. One of the headline grabbing proposals in SAP 10.1 is the proposed carbon factor for electricity at 0.136 - this will mean ground source heat pumps have carbon factors of 0.030 - 0.045 compared to a gas boiler at 0.23. That’s a saving of more than 80% in carbon emissions just by switching heating to ground source heat pumps. With lots of councils across the country declaring climate emergencies, many of which commit to carbon neutral targets ahead of the UK’s 2050 ambition, a growing number of new build developments are already embracing the low-carbon approach. In adherence to the Committee for Climate Change’s recommendation that homes should make use of low-carbon sources of heating, in particular electricallypowered heat pumps that produce no point-of-use emissions, and the new National Design Guide, which singles out ground source heat pumps and district heating systems as recommended heating

technology, Bristol is witness to a number of new build schemes utilising this ultra-low carbon, non-air polluting, and low-cost heating solution to support its 2030 carbon neutral pledge. 133 new homes at Ashton Rise are being built by Bristol City Council using the high efficiency Sig iHouse solution, and heated by individual Kensa ground source heat pumps connected to a shared ground loop array of boreholes. The installation would see each home making lifetime carbon savings of 30 tonnes compared to individual gas boilers, whilst also removing all local NOx emissions, ensuring local air quality is not impacted by the choice of heating system. Across the city, a further 50 affordable homes are being constructed to PassivHaus standards by United Living in partnership with United Communities and the Bristol Community Land Trust. The energy efficient ‘self-finish’ properties will each feature a mini Kensa Shoebox ground source heat pump connected to an ambient shared ground loop array. Complementing the low-carbon ground source heat pumps will be a MVHR (mechanical vented heat recovery) system, making the homes even more energy efficient and further lowering fuel bills for the residents. The homes will be constructed using a single skin Porotherm block, cutting construction time and delivering improved thermal properties over traditional construction. Solar PV panels further reduce costs, whilst supporting a green transport plan which features electric car charging points, a car share scheme and improved pedestrian and cycle access. Communal green space around the homes is also being created with a dedicated and protected green corridor for biodiversity and wildlife including bats, birds, bees and other insects. Evidently the push by local planning authorities to place energy efficiency and carbon saving requirements on buildings that go beyond the requirements of the national building regulations is resulting in some ground-breaking ultra-low carbon, energy efficient developments. Two notable examples are: 1. Bristol City Council require developers to reduce CO2 emissions by 20% and to follow

ENERGY MANAGER MAGAZINE • MAY 2020

a heat hierarchy that encourages renewable and low carbon heating. 2. The Greater London Authority requires developers to reduce CO2 emissions for new developments by 35% (10% must be from fabric improvements) compared to current building regulations. The Future Homes Standard consultation proposes reductions of 20% (option 1) or 31% (option 2) in CO2 emissions for all new dwellings, nationwide. However, it is also consulting on whether to remove the ability for local planning departments to impose deeper reductions via the planning process. This threatens the planning process being a major influence to impact CO2 emissions and achieve the UKs zero carbon targets. The London Energy Transformation Initiative (LETI) views the Standards proposals for Part L 2020 as a backward step ‘in a climate where we need a huge leap forward’, stating that ‘local authorities will lose the ability to meet their climate emergency zero carbon commitments if they are stripped of their powers to go above and beyond the new Part L’. Whilst the Future Homes Standard offers many significant highlights, the lowlight of lower carbon compliance targets is troubling. Kensa has addressed these in its response to the consultation, which is currently under review.

GROUND SOURCE HEAT PUMPS By connecting new developments to a ‘fifth generation’ shared ground loop array feeding individual ground source heat pumps in each new home, housebuilders are not only delivering a sustainable infrastructure to rival and replace the gas grid, they are providing a long-term low-cost lowcarbon heating, and cooling, solution. The rapid recent decarbonisation of the electricity grid and the high efficiency of ground source heat pumps now means that this route to the large scale electrification of heating shows significantly more promise than the decarbonisation of the gas grid. Let’s explore three innovations which coupled with ground

HEAT PUMPS Kensa Shoebox 3kW

Additional energy boosters for Fifth Generation District Heating Ambient Loop

source heat pumps will enable this rapid transformation to take place.

SMART CONTROLS There is a slightly unfortunate trend towards calling anything that is Wifi enabled “Smart”. While it might be more convenient to program a thermostat using your phone/tablet rather than pressing buttons on the thermostat, it is hard to see why this deserves to be called Smart. For a system to be truly smart, it should perform optimisation autonomously – with minimal input from users. If done correctly, the smart revolution could be the essential key to a lower carbon future. Management of the electrical grid with variable demands has never been simpler – consider the classic Coronation Street ending rush for the kettle. A further level of complexity is added by the variability of renewable generation supply from wind, solar, wave and tidal. The traditional solution would be to build additional generating capacity to over-produce and then turn off when not needed. However, the stable source temperature of ground source heat pumps make them well suited to running when the grid can best support it. If properly synchronised, smart control of millions of devices such as ground source heat pumps, electric vehicles and many others will allow the grid to function correctly without the need for over generation. Combined with the low electricity consumption of ground source heat pumps, this will save billions of pounds of capital investment in future generating capacity. Consumers will also benefit as smart metering is giving suppliers the ability to charge consumers different prices at different times of day to reflect the availability of energy. Smart controls will allow householders to automatically take advantage of these dynamic tariffs to run their ground source heat pumps when

Kensa Fifth Generation District Heating with Ambient Shared Borehole Ground Loop Arrays and Kensa Shoebox heat pump

prices are lowest – our modelling shows savings of 25-40% are achievable right now. Better still, lower priced times of day typically coincide with lower carbon grid electricity.

COOLING Warmer summers, improved insulation, larger windows and urban heat islands are combining to increase the need for cooling, which is unhelpful in the fight against climate change. Traditional air conditioning actually makes the situation worse because all the heat taken out of the buildings is pumped into the air around the city, which exacerbates the need for cooling. A ground array with an ambient temperature district heating loop makes an excellent source of cooling – the by-product of extracting heat from the ground all winter is a large area of pre-chilled ground which is conveniently piped to each property (heat pump). Passive cooling can therefore be provided at the extremely low cost of running a small circulating pump. Even better, the heat that you take out of each property is reintroduced into the ground, which improves the heat pump heating efficiency the following winter. For properties that need even more cooling, it is simple to reverse the heat pump hydraulic flows so that the heat pump actively cools the property and sends the waste heat into the ground.

PV-T PANELS Solar panels that combine photovoltaic (PV) cells and thermal (T) water heat exchangers have been

Kensa Contracting Fifth Generation District Heating with Ambient Shared Borehole Ground Loop Arrays and Kensa Shoebox heat pump

around for a while, yet their full potential can be realised by combining them with a ground array. In summer, the ground array cools the panels from 40-50oC down to 15-25oC, which increases the efficiency of the photovoltaic panels by 15-25%. The heat taken from the panels re-charges the ground array which increases the efficiency of the heat pumps by 10-20%. Combining three renewable technologies in this way is a win-win-win, which improves the efficiency of each technology independently and results in a more efficient overall system, bill reductions and carbon reductions.

TIMESCALES These innovations all take advantage of existing technology but combine them in ways that bring huge benefits to the decarbonisation of heat. They are ready to go and future proofed which means they can be deployed now with no regrets and their benefits will increase with time as the electricity grid evolves and decarbonises. www.kensaheatpumps.com

HVAC

THE HOMES ACT UPDATE: WHY TACKLING CONDENSATION IS MORE IMPORTANT THAN EVER Following the introduction of the Homes (Fitness for Human Habitation) Act in 2018, increased pressure has been put on landlords to ensure their properties are adequately maintained. Condensation is a topic that continues to dominate the housing agenda, with misdiagnosis and tenant behaviour patterns negatively contributing to the problem. With this in mind, Paul Harrington at Elta Fans highlights the major issues surrounding condensation, and what landlords can do to tackle the problem.

tatistically speaking, currently over 1/3 of UK households operate on a tenantlandlord relationship, with occupants reliant upon their landlords to fix issues within the property. The Homes Act aims to ensure that rented properties are safe and healthy for habitation – in other words, free from things that could cause serious harm. As of March this year, this has been updated to include all rented properties, including those who have only just started renting. In some instances, it has given tenants greater power to action change, if they do not feel their property is maintained to a high enough standard, they can now take the matter to court. The court will then decide if it is fit for human habitation by considering matters which are set out in section 10 of the Landlord and Tenant Act 1985. One of the most common issues that landlords have faced, especially during the colder months is condensation. This occurs when warm air collides with cold surfaces, such as windows or external walls, and as a result can lead to a type of mould that has damaging effects on both health and structural integrity. This is a real problem for the NHS, who according to the Local Government Association, spends £2.5 billion a year treating people with illnesses directly linked to living in cold, damp conditions1. It is for this reason that landlords and contractors must get to grips with the causes and cures for condensation.

OCCUPANT BEHAVIOUR One of the main reasons that condensation is so prevalent in rented housing is its link to tenant behaviour. There are a range of activities that exacerbate these levels, especially in social housing conditions. Drying clothes indoors, for example, is something that is unavoidable for anyone who doesn’t have the luxury of outdoor space. Another common cause of condensation is the increasing inability of tenants to afford their heating bills. According to the Department for Business, 1 https://www.local.gov.uk/parliament/briefings-andresponses/cost-unhealthy-housing-nhs-house-commons26-february-2019

Energy & Industrial Strategy, 11% of UK households exist in fuel poverty, which means that houses are colder than they should be. Not only does this have some serious direct health implications, but also has a knock-on effect on condensation levels. This just highlights why the fight against condensation is such a challenging one for landlords, and while they may have little to no control over what their tenants do, this combined with the Homes Act places more emphasis on the need to be responsive and act quickly.

AVOIDING MISDIAGNOSIS While being responsive is crucial, an all too frequent problem that both tenants and landlords run into is the misdiagnoses of condensation as dampness or mould. Not only does this not address the problem, but it can prove costly in time and expense as damp-orientated solutions are incorrectly invested in. To help avoid misdiagnosis, landlords and tenants should avoid taking matters into their own hands and call on professionals. Damp experts should then be proactive when attending call outs and be able to correctly inform landlords on instances where it is condensation rather than damp, and recommend measures to alleviate the issue.

EFFECTIVE VENTILATION In an ideal world, we could simply reduce the amount of condensation within our homes by controlling the amount of moisture inside them. However, in many circumstances this

ENERGY MANAGER MAGAZINE • MAY 2020

just isn’t possible, and alternative methods must be applied, such as the investment in effective ventilation. This must then be balanced with the need for energy efficiency, in order to prevent fuel poverty issues from worsening. Intelligent PIV units are designed to control condensation and gently ventilate the home. They are capable of adjusting air flow depending on the moisture content and temperature of incoming air during the winter months. This ensures optimal thermal comfort for tenants, without incurring the high energy costs associated with using a heater, and integral controls allow the unit to be responsive to the individual requirements of a home.

THE KEY CHANGES It’s clear to see that the types of behaviour that increase instances of condensation are largely the same as they always have been. The Homes Act however, has understandably been a key change for landlords who find themselves under more pressure to act and be responsive. The spotlight has been shifted onto the housing providers, and therefore the conditions of their properties. Everybody though, has a responsibility to understand the symptoms, causes, and treatments for condensation, whether they are a landlord, damp proofer, or anyone associated with delivering ventilation to a home. To help with this, Elta Fans has created a guide to combatting condensation, which can be found here: https://www.eltafans.com/divisions/ residential/combatting-condensation/

POWER GENERATION

POWER DENSITY — CONSIDERATIONS FOR HOSPITALS

uring a diesel generator upgrade, as part of a hospital refurbishment or expansion, it can be tough to meet the requirements of the space, particularly if the engine room is small or difficult to access. To achieve a good balance between power output and available space, hospital management teams can opt for generators with a high power density.

SPECIFYING A SYSTEM Although the generator must be able to cover 100 per cent of hospital power in the case of an outage, futureproofing isn’t as simple as just buying bigger generators to meet extra capacity. If hospital teams over-size their system by choosing a generator with a higher rating than needed, the units will take up more space and have a higher maintenance and servicing requirement. Larger units also lead to increased capital costs, something which is increasingly hard to justify. At the same time, smaller units may not provide enough power, leaving hospital procurement teams with a tough decision. Engine manufacturers have been working to decrease the size of their units, while maintaining the same power resilience. This results in generators with higher power density — a measurement for the amount of power a piece of equipment produces for its size. While a standard hospital generator used to offer 2.5MVA standby, convention now is usually above 3.0MVA. One example is the Cat® 3516, which was originally rated at 1650 kVA, but can now achieve over 3,000 kVA, all from a very similar footprint. Aside from power density, using compact generators means hospitals also benefit from the need for less ancillary equipment and generators that are cheaper to transport, install and maintain.

POWER DENSITY IN PRACTICE As an example, Finning has provided Guy’s Hospital in London with three Cat® C175-20 generator sets with an output of 3200ekW, the highest output available from a single high-speed generator set in the UK. The system will go on to provide a combined 9600ekW of

Whether it is a storm, a flood or a general blackout, hospitals must be able to sustain power. To futureproof their standby power needs, hospitals often upgrade their standby generator systems. Here Jason Harryman, UK Sales and Business Development Manager for Electric Power at Finning UK & Ireland, exclusive distributor of Cat® generators in the UK and Ireland, explains why a generator’s power density matters to the NHS. reliable, mission critical standby power. Talking about the project, David Porter, Head of Compliance at Guy’s and St Thomas’ NHS Foundation Trust said: “Due to the spatial constraints, we considered three different sizes of engines and appointed Finning, which offered the C175-20, because of its compact size and high power output. The small footprint of the C175-20 means that the new units can be housed within the existing generator rooms without any major building modifications.” To reduce the risk of the power going out, hospitals may think that a

more power dense generator means fewer units are required, and therefore fewer points of failure. However, demand for standby power has increased so significantly over the years, numbers have actually increased. The key to achieving a low cost of ownership is to optimise the generator to match the required needs.

RENEWABLE ENERGY

BIOENERGY – BRITAIN’S ENERGY FUTURE?

INTEGRATING BIOENERGY INTO SMART GRIDS Bioenergy is recognised as a key renewable energy source and an essential component of a low carbon energy economy. According to the Committee on Climate Change, bioenergy could provide up to 15 per cent of the United Kingdom’s energy demand by 2050. Here, Alan Binning, Regional Manager at energy grid software provider, COPADATA, examines the potential of bioenergy generation and why, to integrate this valuable energy source into the smart grid, intelligent technology is essential.

n June 2019, the UK became the first major economy to set a legally binding commitment to reach net zero carbon emissions by 2050. The uptake of bioenergy generation, currently responsible for seven percent of energy demand, has contributed to the UK achieving the highest decarbonisation rate of all G20 countries, sitting at 3.7 per cent. Unlike some renewables, bioenergy generation requires the use of biomass fuel to produce energy. That includes anything from food and agricultural waste to timber, plants and even sewage. The availability of biomass is good and rapidly expanding with the advancement of new technologies, especially in terms of anaerobic digestion and food waste. However, this doesn’t mean bioenergy will be enough to be the sole generation of energy – it will be a key

complimentary source to back up other types of renewable energy. But how can this energy source be integrated onto a grid designed for fossil fuel-based generation? Continuous depletion of primary fuel resources and concern about pollution means that uptake of renewable energy, including bioenergy, is essential. As a result, the development of smart grids has gained huge strategic significance. Wind and solar power generation are undoubtably two key players in the commitment to lower carbon emissions. However, the intermittent and fluctuating nature of these resources means that controlling and monitoring their output to the grid is a difficult task. Unlike wind and solar energy, which are dependent on weather and therefore volatile, power from bioenergy can provide a flexible method of integrating these renewable sources effortlessly to the grid. Bioenergy can be used to relieve the pressure on the system level management of the grid by making it more balanced, playing a focal role as a stabilising agent in renewable power supply. Bioenergy generation can also be a key tool in reacting to energy trading; generating energy when it is in high demand. However, this is only possible with accurate data acquisition and monitoring. Integrated, seamless information flows from bioenergy generation sites are critical success factors for implementing this source. Using a distributed software platform like zenon, allows operators to paint a full picture

ENERGY MANAGER MAGAZINE • MAY 2020

of bioenergy generation; through control of the generation plant, constant monitoring of the data collected and the monitoring demand from the grid. Using the communication enabled by a platform like zenon means that the grid and its power sources can react to energy trading by identifying periods of high demand. It also allows for extensive asset distribution, generating a map of potential energy in storage, for example, and making that data available to all operators on the grid. Not only a suitable system for the management of bioenergy generation, zenon is a unifying element that adds a layer of intelligence between systems on a smart grid. As well as connectivity, zenon also assumes control of the contextualisation of data, to make it useful and easy to evaluate. Through cloud connectivity, the system allows for secure distributed fleet management across multiple generation sites and locations, which can be configured and maintained from a central location. Put simply, operators can make datadriven decisions, wherever they are. Bioenergy could provide the flexibility to balance the fluctuating characteristics of other renewable sources, like wind and solar power. Deployment and effective use of control technologies like zenon will not only improve performance and operations of bioenergy sites, but will allow the renewable energy source to continue to grow – further chipping away at the United Kingdom’s dependence on fossil fuel-based power. www.copadata.com

WHICH ARE THE FACTORS AFFECTING SOLAR POWER EFFICIENCY?

olar power systems are considered a key tool in the energy supply for the present and future generations. Several factors have promoted the development of photovoltaics such as environmental concerns, incentives and tax deductions, a more performing and less expensive technology and the need to replace carbon fossil energy systems with renewables to ensure compliance with the objectives set by the Paris COP y limit global warming to 1.5 Â° C A solar cell or photovoltaic cell is a device that converts the sunlight into usable energy. The amount of sunlight that can be converted into electricity is referred to as solar cell efficiency. There are some factors which should be taken into consideration when opting for solar panels to guarantee the optimal efficiency.

least current. When a cell is shaded, the whole series is virtually shaded too. To prevent the loss of energy, the installation usually includes bypass diodes. Bypass diodes are wired in parallel to the solar cells. When a solar cell is shaded, the bypass diode provides a current path that allows the string of connected solar cells to generate energy at a reduced voltage.

THE TEMPERATURE

ORIENTATION, INCLINATION, LATITUDE OF THE PLACE AND CLIMATIC CONDITIONS

The temperature influences the solar output because of the intrinsic characteristic of the semiconductor material. The efficiency of the solar panels increases when the temperature drops and decreases in high temperatures, as they lower the voltage across the cells.

ENERGY CONVERSION EFFICIENCY The solar module has a different spectral response depending on the kind of the module. Therefore, the change of the spectral irradiance influences the solar power generation. The energy conversion efficiency is increased by reducing the reflection of the incident light.

SOLAR SHADINGS Solar PV panels are very sensitive to solar shadings. Total or partial shading conditions have a significant impact rate on the capability of delivering energy and may result in lower output and power losses. Cells in a solar panel are usually connected in series to get a higher voltage and therefore an appropriate production of electricity. But when shading occurs, this structure presents some limitations. In fact, when a single solar cell is shaded, the current of all the units in the string is determined by the unit that produces the

SOLAR SHADINGS The installation of the photovoltaic modules must take into account some factors to take full advantage of solar radiation: the orientation, the inclination, the latitude of the place, the climatic conditions. The correct consideration of these variants will help ensure that they produce maximum energy by being exposed to the greatest intensity of solar radiation for the longest period of time.

OPERATION AND MONITORING O&M services help with the management of the implementation of certain processes to avoid or mitigate potential hazards and to guarantee the optimal return on investment. Operations mainly consist of the remote monitoring and control of the PV power plant conditions and performance. Monitoring software provides access to all data collected, which can be used for different purposes: defect detection, performance analysis, improvement, predictive maintenance, and security. A good monitoring system will provide information on the production, alarms and analytical data, in a timely, efficient and precise manner to detect any anomaly of the PV plant.

MAINTENANCE Solar panels are very durable, main warranties last for 15-25 years. However, cleaning solar panels is important to maximize the amount of light available to turn into electrical power. Making frequent physical inspections can help solar panels absorbing light effectively. www.trace-software.com

CARBON OFFSETTING

THE CLIMATE CAN’T WAIT, SO WHAT’S THE SOLUTION? THE CASE FOR 100% CARBON NEUTRAL GAS. James White, sustainability executive at ClimateCare.

reen tariffs, centred around renewable electricity, have become commonplace within the energy sector. In 2019, renewable electricity provided more electricity to UK homes and businesses for the first time, surpassing all other forms of fossil fuel energy generation. Less than ten years ago, fossil fuel represented four fifths of the UK’s electricity generation. As renewable electricity becomes the norm - organisations are turning their focus to another component of their energy supply; gas. Solutions for UK ‘green gas’ or biomethane do exist, however, there are currently challenges to delivering this at the scale required to provide the UK with a 100% carbon neutral gas supply. This article explores the current status of UK green gas, and the alternatives available to those within the energy industry.

WHAT IS UK BASED GREEN GAS? Emissions from the use of natural gas are the primary emissions source in residential and public sectors, accounting for 20% of all carbon emissions in the UK in 2018. As a result, solutions are increasingly being explored to tackle this impact, including UK ‘Green Gas’. Green gas, or biomethane, is made through anaerobic digestion. This uses bacteria to break down organic materials – like food or farm waste – to release biogas. The biogas is purified and turned into biomethane, which

is injected into the gas grid. Once in the grid, it’s piped into homes. In contrast to natural gas, Biomethane is produced from renewable sources, like food and farm waste and is carbon neutral. Natural Gas reintroduces carbon dioxide (CO2) into the atmosphere that has been locked away for millions of years, whereas biomethane is produced from organic materials that absorbed carbon dioxide while they grew. This means that when it’s burned, it only releases that same amount of carbon dioxide. In 2019 Green Gas supplied one million UK homes. This was a significant increase since 2017, with this anticipated to surge over the next three years to up to £400m of investment in the sector, according to the UK’s four main gas network operators. However, Green Gas through Biomethane represents just 4% of the UK’s annual demand for green gas. Supply is not able to meet demand, and unfortunately bridging the gap will take significant time and resource. There is a clear need for an interim solution. And this is where carbon offsetting comes in.

ENERGY MANAGER MAGAZINE • MAY 2020

WHAT IS CARBON OFFSETTING? Carbon offsetting provides a means to mitigate the impact of emissions now. Used by international Governments, businesses and NGOs (and recommended by the UN) many in the energy industry are now exploring how they can use carbon offsetting to compensate for their residual emissions. Put simply, offsetting means compensating for your carbon emissions by funding an equal reduction in emissions elsewhere in the world. These emissions reductions are generated by projects around the world which adhere to internationally recognised and independently verified standards to ensure that the climate and social benefits they deliver are both tangible and additional.

HOW DOES CARBON OFFSETTING HELP THE PLANET? Carbon Offsetting is a vital tool in tackling climate change, mitigating the impact of emissions we create

CARBON OFFSETTING now, whilst we work towards reducing the emissions of our activities more concretely. It provides a key means to help us in achieving our ambitions in relation to tackling climate change, helping us to bridge three things: 1. The Ambition Gap: Government ambition is falling short of what is required with regards to reducing emissions to meet the target of 1.5. Following the UN Climate Action Summit, critics noted that 14 high-emitting countries, covering 26 percent of global emissions, currently have no plans to submit new emissions targets ahead of the Paris Agreement coming into full effect next year. 2. Finance Gap: The UN’s Intergovernmental Panel on Climate Change (IPCC) says that an annual investment of $2.4 trillion is needed in the energy system alone until 2035 to limit temperature rise to below 1.5 °C from pre-industrial levels. (That is around 2.5% of the world’s economy.) At present, “Neither the amount of financial flows nor their direction is sufficient to keep temperatures below 2 °C, let alone 1.5 °C,” says Ottmar Edenhofer, former co-chair of the IPCC’s working group on mitigation of climate change. Additional finance (such as through carbon offsetting) delivers additional finance to the battle on Climate Change, support a low carbon transition globally. 3. Time Gap: There is a consensus that businesses and governments are not acting fast enough to tackle Climate Change. At COP24, United Nations Secretary-General Antonio Guterres stated that the world is “way off course” in its plan to prevent catastrophic climate change, a point he reiterated at COP25. With COP26 currently delayed, climate ambitions are again pushed back, leaving less time to act. Offsetting provides a means to mitigate emissions now, buying us more time to tackle climate change through direct reductions. The Global Carbon Project found that the total carbon dioxide emissions from fossil fuels and industry amounted to ~33 Gt of CO2 in 2019 (IEA, 2020), giving us less than 20 years before we exceed the target emissions for 1.5-2°C.

Quite frankly, we are running out of time to tackle climate change through solely reducing our emissions. Carbon offsetting is the only way to take responsibility for current emissions right now, whilst we work out other ways to bridge the time, investment and ambition gap currently being faced in the direct reduction of our emissions

HOW DOES CARBON OFFSETTING HELP THE ENERGY INDUSTRY? Carbon offsetting provides an interim alternative to UK based green gas, allowing industry participants to provide verifiable carbon neutral gas through supporting high impact projects in the developing world. Carbon offsetting has several advantages in comparison to UK based green gas at present, including: • Carbon Offsetting tends to be more cost effective than UK based green gas, as most carbon offset initiatives operate at large scales in the developing world; • Availability of carbon offset projects is high, with supply of emission reductions sufficient to fulfil demand in the utilities sector; • It’s possible to offset through a wide array of project types which deliver a variety of different impacts. These include protecting biodiversity, improving local people’s livelihoods, and enhancing equality.

WHAT DOES SOCIETY THINK OF CARBON NEUTRAL PRODUCTS? Demand has never been higher for green products. According to a survey conducted by Unilever in 2018, 33% of people were motivated by green credentials in their selection of the products and services they bought. This included utilities. This number has grown since 2018, with a 2019 study by Futerra suggesting that 88% of people are now looking for brands to provide them with sustainable products and services. This demand isn’t limited to individual customers either. In fact, organisations, whether large or small, private or public, are also increasing interested in the green credentials of the services and products that they use. A recent Business Green headline suggested that ‘Eight out of 10 small business bosses want to be more sustainable,’ based on a survey of 100 CEOs of British SMEs. The survey found that 84% said they

believe their customers are interested in seeing businesses act sustainably, and 80% said they plan to introduce more ethical/green practices into their business over the next three to five years. Companies are responding to the above through developing carbon offset gas tariffs, which are designed to engage customers through this demand for high quality green products. This is a trend that we expect to continue, much as utilities suppliers have developed green electricity tariffs in the past.

CONCLUSION Certainly, the future is full of challenges and of course, opportunities for the energy sector. The challenge will be to meet the need of the industry to decarbonise at scale, whilst tackling residual emissions now. All this, alongside creating an offering which captures the interest of consumers and reflects internationally recommended best practice. There are several different approaches and strategies out there. In my opinion, understanding how best you can combine these for your organisation and to solidify for a leading position within the industry, is something that we would encourage everyone within the industry to consider carefully. https://climatecare.org/ James White develops high-impact programmes for our new partners, based on our trademark Climate+Care approach.

DRIVING THE FUTURE

FUTURE-PROOFING EV INFRASTRUCTURE Andrew Toher, Head of Customer Insights Enel X UK

onceptually, charging an electric vehicle is a simple task. In reality, providing the infrastructure to support e-mobility is giving energy managers a lot to think about. However, with the right approach, businesses can optimise their investment in charging infrastructure so that it works for them and their end users.

THE BUSINESS AND LEGISLATIVE DRIVERS Transport accounts for around a quarter of global emissions. Consequently, many businesses are looking to lead on climate change action by decarbonising their vehicle fleets and boosting EV use by providing workplace charging. The UK has passed legislation to ban sales of new petrol and diesel vehicles by 2035 at the latest, and is simultaneously looking to accelerate the EV market by providing attractive tax-breaks to business users. Meanwhile, some businesses are looking to lead on zero-emission transport as a tangible demonstration of their commitment to combat climate change. For delivery firms and logistics companies where transport is the core of the business, those who can offer a net-zero service first will attract new customers. This potent combination of government legislation, financial incentives and user demand is compelling businesses to act on EV charging. For businesses looking to invest in onpremise EV charging, it’s important that they consider the big-picture view of their energy needs first, and consider both operational and procurement issues before rushing into projects. Some of the key issues include: site capacity and load; choosing the right charger; taking a modular approach to design; identifying grid balancing opportunities and signing up to the right supply contract.

SITE CAPACITY AND LOAD For many sites, considering the impact of adding EV charging stations

on site power load is fundamental to the feasibility and cost of the project. While a basic parking facility might have a power load of just 5-10kW for features like lighting and barrier entry, adding a single rapid charging unit will increase the peak power load for that facility by 5-10x. Providing workplace charging for EV fleets introduces a key challenge – how to manage overall power loads at facilities. Large sites with half-hourly billing will have agreed a maximum import capacity (MIC) with their supplier. Capacity needs to be in line with demand, and exceeding the MIC incurs financial penalties. There may also be a risk of exceeding total supply capacity by using EV charging stations while operating normal electrical loads in buildings. The Distribution Network Operator

ENERGY MANAGER MAGAZINE • MAY 2020

will be involved in looking at worst-case power load scenarios to assess whether network upgrades are required, which can take many weeks and require significant investment if the business has to pay to reinforce the network. The extent to which the customer has to pay for these connection costs is under review as part of the Access and Forward Looking Charges Review, and could be more onerous in future. By monitoring the building’s energy consumption, the charging process can be remotely managed in real-time while making the most of the existing available power. This approach can avoid the need for expensive network reinforcement, enabling optimal use of charging infrastructure while minimising costs through dynamic load balancing.

DRIVING THE FUTURE SPECIFYING CHARGERS Rather than taking a one-size-fits-all approach, it is necessary to consider the needs of users and the potential business models when specifying charging solutions for public and private infrastructure. For example, a 50kW fast charger may be too fast for a shopping centre or a business park, where visitors are expected to stay on-site for a number of hours. A retail park, pub or motorway service station will have different business requirements that are met by different charging solutions. Some operators of public charging infrastructure earn revenue by renting parking spaces from the site owners for a fixed annual fee, while the site owner benefits from an additional customer amenity and, in some cases, a share of the charging revenue. Optimising revenue and return on investment requires careful choice of the charging solution to offer, i.e. the right charging solution for the right setting to achieve best customer experience and best return on investment.

MODULAR PLANNING Balancing the needs of users with a design that satisifies those needs will be challenging for any business committing to providing EV infrastructure for employees. There are many variables at play, including the rate of uptake of e-mobility, EV battery range, technology advances and how drivers choose to charge their cars; whether keeping them ‘topped up’ or recharging from empty. Taking a modular approach to specifying on-premises EV charging reduces investment risk. By planning for future expansion while implementing what’s needed today, businesses can review usage patterns and power loads and base their decisions about future needs on real data.

SUPPLY CONTRACTS Another consideration for businesses is whether they are signed up to the most appropriate supply for EV charging. Some energy suppliers are introducing innovative tariffs that are highly suited to smart EV charging. However, it may

become more difficult to realise benefits from off-peak time-of-use tariffs as EV charging becomes the norm. Beyond simply agreeing to a bespoke tariff for energy use, businesses can also choose how their power is generated; use of ‘green’ tariffs; the pricing/ payment/billing model; financing for the new assets; onsite/offsite generation; resilience measures; the use of energy management technology and their own distributed assets for generation, demand response or energy storage.

GRID BALANCING Whether businesses can usefully use their EV fleets as energy storage assets or virtual power plants to help balance the grid is still some way off. Using EVs for energy storage requires vehicle-to-

grid (V2G) technology and the ability to discharge the car’s battery to the grid. Despite successful proof-of-concept V2G trials, there are some practical barriers to implementing V2G today, foremost of which is limited EV manufacturer support for bidirectional charging.

PLANNING FOR THE FUTURE Workplace EV charging infrastructure will become prevalent in the coming years, as businesses look to enable e-mobility. By taking a holistic view of energy use and planning for the future, businesses can embrace zero-emission transport without later regretting investment decisions they might make today. www.enelx.com

DRIVING THE FUTURE

CHARGING AHEAD ON THE ROAD TO ZERO EMISSIONS Richard Baker, CEO of GeoSpock

he UK transport sector contributes more to carbon emissions than any other. It’s therefore no surprise that the government is encouraging more people to switch to electric vehicles (EVs) In February, the UK government brought forward their ban on new petrol, diesel or hybrid cars from 2040 to 2035, paving the way for greater adoption of hybrids and EVs that run on cleaner energy. However, it is not that simple – the EV transition strategy lacks a few crucial pieces. Deloitte has estimated that the global EV market will reach a tipping point by 2022, when the cost of ownership of an electric vehicle will be on par with the internal combustion engine (ICE). Unfortunately, it could also result in a supply gap of almost 14 million EVs in 2030, undermining government efforts. The aim is clear – moving toward the electrification of the private and public road transport sectors. However, there’s still a long way to go and many things to consider.

COMPLEXITIES OF A NATIONAL CHARGING INFRASTRUCTURE In January 2020, a new Ipsos Global study revealed that consumers ranked the location and availability of charging stations as one of the biggest barriers to EV adoption. To address this, the Conservative government made a £500 million election commitment to expand the ‘fast-charging network’. This could lead to a substantial

improvement from the 15,500 chargers / 26,500 plugs which are present, according to Zapmap. However, compare that to the 8,400 fuel stations and 68,000 pumps currently in the UK, and we have a better understanding of the current situation. If we accept that the number of charging stations has to increase, and that the government is reacting, we must consider their location. Choosing the best sites are complex due to competing factors such as local grid constraints and EV ownership density. Unlike traditional refilling at petrol stations, it’s not a one-size-fits-all system. The type of charge point best suited to each location will depend on the profile of each area and the driving habits of EV users within it. The wide range of charging speeds, and potentially long recharge times, means EV charging infrastructure needs to fit alongside existing driving behaviours and activities. If, for example, the majority of EV drivers prefer to charge up their vehicles while they do Saturday’s shopping in a particular district, then that is vital data for charge point locations.

CHARGE POINTS AS DATA GOLDMINES Operational data on charging – such as time of day, charge duration, the amount of power delivered and what type of connector was used – is now collected in conjunction with commercial data related to payment methods and transaction amounts. In addition, modern EVs are far more digitally enabled than traditional vehicles, constantly recording high volumes of additional spatial data during the day. Taking into account all the different variables makes it a delicate balancing act to decide what the demands are for drivers – whether visiting any given neighbourhood supermarket or central business district car park now, or in the future. That’s where the power of geospatial data will help. This can

ENERGY MANAGER MAGAZINE • MAY 2020

highlight unique usage patterns in specific areas and shed light on which is the best route to take when it comes to EV infrastructure investment. Once you have a clear picture of charging use and behaviour in a particular location, you can remove a lot of the guesswork from charging infrastructure decisions.

THE “OVERPOWERED” ELEPHANT IN THE ROOM We are in the energy age – every nation is looking to fill the void left by fossil fuels and make efficient, futureproof decisions. As EVs become more widespread, electrical demand will grow and, on current estimations, outstrip the capacity of local power grids. This in turn will force EV charging networks to compete with each other in infrastructure projects for electricity. There is also concern over electrifying public transport. UK buses and trains are due a complete overhaul, purely from an efficiency standpoint. Factor in electrification, and the public transport network needs huge and ongoing investment if it is to meet modern and future demands. The UK government has set bold and welcome plans for EVs. It is the first step in making the UK transport industry fit for purpose. However, simply banning or phasing out old, inefficient vehicles and expecting private companies to develop new technology to fill the void will not suffice. We need to make decisions that will benefit us, not just for the here and now, but for the unforeseeable future. Building charging points is to be lauded, but what happens if the technology is made redundant, or if public habits change? Instead, the government must look to invest in data, creating a holistic transport hub to understand activity and trends in the industry. Only then can we make informed, real-time decisions and ensure the national move to electrification is moving forward in the most efficient and flexible way possible. https://geospock.com/en

THESE ARE THE CITIES MOST PREPARED FOR THE ELECTRIC CAR TAKEOVER • The Government announced plans to ban the sale of conventional vehicles by 2035, Brits remain dubious about switching to electric cars • Study reveals how well UK cities were prepared as of 2019

s the government announced that they will be bringing forward the plan to ban the sale of conventionally powered vehicles by 2035, new research has revealed the UK could hit its target of ‘most vehicles on the road being low emission’, as early as 2034, however, Brits have major concerns about making the switch. The research from leading car parts retailer, Euro Car Parts, looked at the UK as a whole, as well as drilling down into the capital and also the UK’s 10 most congested cities outside of London, to see how prepared they are to make the switch. Based on calculations that consider factors such as the population, the amount of public charging points and their increase rate since January 2019, as well as the volume of alternative fuel cars currently registered, the research revealed Southampton will be ready for the electric takeover the quickest1. The southern city currently has 77 charging points, a 13% increase since January, alongside a relatively low population compared to other major cities and 1,023 alternative fuel cars registered. London has seen a 66% increase in charging points since the start of the year to almost 4,000, however due to

its vast population (9m) and number of electric vehicles already on the road (123k), it still has a long way to go to be completely ready for the electric takeover. Here are the UK’s most congested cities in order of how ready they are for the electric takeover:

10,000 low emission vehicles by 2034, suggesting the UK’s roads won’t be fully equipped for the transition, and may not meet day-to-day demand. The number of charging points weren’t the only concern, with the distance-per-charge a worry for half

Looking at the UK as a whole, a Department for Transport report in 2018 stated only 2% of registered vehicles were low emission. And while this seems a long way off target, the YoY growth2 shows the UK has had a 37% increase in low emission cars since 2016. If it continues at this rate, the UK will have 38.2m low emission vehicles on the road by 2034, leaving the government hitting its target an impressive 16 years before its 2050 deadline. Despite the target already predicted to be hit earlier than anticipated, Euro Car Parts’ research revealed the nation’s drivers aren’t quite ready to take the plunge. The research with 2,000 UK drivers highlighted ‘not enough charging points’ and ‘being stranded without charge or accessibility to charging services’, were their main concerns (66%), and according to YouGov3, only 4% would consider purchasing an electric car as their next vehicle. Looking further into the volume of charging points, the UK has seen an average of 28% increase in charging points being installed YoY since 20164. If this rate continues, the UK is expected to have 322 public charging points per

of motorists (47%), as well as their electricity bills increasing (27%) and it actually being more costly than owning a petrol/diesel vehicle (22%). Commenting on the findings, Chris Barella, Digital Services Director at Euro Car Parts, says: “It’s interesting to see that while figures suggest the government are on track to hit their low emission vehicle target, perhaps even earlier than anticipated, the nation’s views and attitudes towards alternative fuel vehicles, means we still have a long way to go. “It seems the biggest concern is the number of charging points and it’s understandable why. If the YoY figures are anything to go by, we simply won’t be equipped to supply the demand, however it’s encouraging the government is increasing its funding for charging points in residential areas. Hopefully seeing more around the country will inspire the nation’s drivers to make the switch and help us to achieve the initiative as early as predicted.” For more information on how prepared the UK’s major cities are for the electric takeover, please visit: https://www.eurocarparts.com/ blog/the-uk-cities-most-preparedfor-the-electric-car-takeover

LEGISLATION

ARE BUILDING CERTIFICATIONS ‘GREENWASHING’ THE ENERGYEFFICIENCY INDUSTRY? With so many industry buzzwords and certifications, it’s increasingly hard for people to distinguish between what are, and are not, relevant environmental credentials.

e are all aware of the buzzwords. There are green and healthy buildings, zero-carbon buildings and the Living Building Challenge, which are backed up by certifications such as LEED, BREEM, GRESB, ISO50001 and WELL. While these green strategies have their origin in well-meaning environmental causes, a certain ‘Greenwashing’ has muddied the waters. The term greenwashing was coined in the 1980s in response to companies making bold claims about their environmental credentials. Over 30 years later, the phrase is back, but this time greenwashing has become a lot more convincing due to the amount of green policies which a company can pretend to adopt. Also, people are more ready to spend a premium on green products in order to support mainstream concerns for the environment. Now, this false message of selling a green product or service has predominantly migrated into commercial buildings. These attributes range from the material ingredients and toxicity to identifying material extraction damage to local eco-structures and the environment, to the actual performance of the building itself regarding energy and water consumption. With 600 rating tools available, it’s not only daunting to quantify what these mean, it’s also more possible than ever to be misled by ambiguity in the industry. Certainly, some companies are investing in Energy Monitoring Solutions as a tick-boxing exercise to achieve an energy efficiency standard mostly in the construction stage of a building. Most certifications will have a minimum requirement of monitoring main energy and water meters and additional points can be achieved from metering at subdistribution boards and branch circuits. Yet certain developers found an easy way out by installing energy meters which are connected directly to terminals with no data being collected, but the box is ticked.

WHY INVEST IN ACHIEVING BUILDING CERTIFICATION? There are many social and economic impacts for going green. Such buildings create a more productive workplace for occupants and therefore help with the mitigation of climate change. Green buildings also see benefits for corporate reputation while the building itself has lower volatility in the market thus allowing for higher rent.

HOW TO DIFFERENTIATE GREENWASHED PROPERTIES FROM ENVIRONMENTAL PROPERTIES Potential tenants of a green building should look at the building holistically. For example, does the property manager have direct employees responsible for reducing energy consumption? Or do they hire a thirdparty consultant to advise them? If the answer is yes to either question, then that is a good sign. Landlords are not greenwashing if they have invested in the development and implementation of energy management procedures. Furthermore, if an organisation believes energy management is the responsibility of everyone in their building – and is guided and supported by the Facility, Property or Energy Manager – than that is another good sign. Also, companies that have bought into being green will assess their energy performance through Energy Monitoring Software and share energy consumption data with all employees. From the data collected they will create and implement an energy plan to achieve their energy goals.

THE NEXT STEP For any organisation adopting a green strategy, the logical step is investing in energy monitoring software that will measure all utilities from main meters to sub-distribution boards. Such software provides Property Managers with the

ENERGY MANAGER MAGAZINE • MAY 2020

data needed to reduce energy costs and comply with their reporting requirements. Energy measurement software benefits the customer in the following ways: • Identify significant energy users that represent the highest percentage of total energy use • Establish and monitor KPIs and benchmarks • Report generation for building standards listed above • Email alerts when consumption targets are breached or when electrical system issues occur • “Hour’s Run Clock” that will show usage of individual units/circuits, once the device is serviced the hour’s run clock can be reset • Ability to calculate, track and report on CO2 based on their actual energy used/saved depending on their source of energy Along with the above benefits, the main challenge is the behavioural change of a building’s occupants. With this in mind, Acutrace has developed a method to allow all occupants view data relevant to them or their department through public boards throughout the hotspots of their building. Public boards are beneficial in the following way: • It creates a ‘Prius’ effect which is a current green building phenomenon • Employees will be provided with real-time data and statistics which results in behavioural change • This small feature will yield big results as employees’ habits will be more energy friendly If you have any queries or would like Acutrace to survey your building’s current infrastructure contact: gavin@acutrace.com / 00353 87 141 9040 / 00353 1 5180140

FINANCE

ENERGY-AS-A-SERVICE: ENABLING UK MANUFACTURERS TO TURN REGULATORY COSTS INTO COMPETITIVE ADVANTAGE

Mark Kelly, Project Development Director, Distributed Energy Systems (DES), Siemens and Mark McLoughlin, Key Account Manager - Siemens Industries and Markets, Siemens Financial Services (UK) examine how smart financing is enabling manufacturers to harness energy savings to make them more competitive.

he manufacturing industry is under pressure to lower carbon emissions by reducing its energy use. Since business and industry is responsible for around 25% of the UK’s carbon emissions,1 this has led to the introduction of a swathe of legislation, designed to make organisations manage their energy consumption more sustainably. At the same time, rising energy prices are increasing production costs. These regulatory and financial pressures are even more urgent as shareholders are increasingly aware of how fuel costs, network costs and poor energy purchasing decisions are harming their investments. In addition, UK businesses without 1 BEIS, The clean growth strategy, Oct 2017

an energy resilience strategy are said to be risking up to 17% of their revenue,2 and yet one third of energy decisionmakers say their organisation is ‘not prepared’ for a disruption to their energy supply from a temporary grid failure.3 To ensure businesses maximise the potential competitiveness benefits from meeting their regulatory obligations and financial demands, it is vital that they fully understand their responsibilities and how to manage them most effectively. Although many manufacturers have already built up their own inhouse energy management expertise, partnering with dedicated energy solution providers can secure better financial and strategic outcomes and allow them to focus on their core competencies. Strategically-sound suppliers are prepared to take a long-term and evolving view of what energy solution best meets each industrial manufacturer’s unique needs, using a holistic, integrated, site-specific approach. Partnered with an outside expert, businesses are shifting towards generating their own heat and power to bring energy production closer to its use. This enables manufacturers to cut energy wasted from transporting electricity from one side of the country to the other. Excess energy is captured and re-used, while production line processes are adjusted to optimise energy-efficiency. An integrated on-site energy supply solution can immediately reduce operating costs, reduce utility negotiating power, and provide a more secure, resilient energy supply. Overall, through a mix of flexible, decentralised and renewable energy generation strategies, a trusted partner can help businesses reduce energy costs by 25-40%.4 Energy service partners can also enable industrial manufacturers to access new digital tools such as data analytics to 2 SmallBusiness.co.uk, Businesses risk 2.8 million of annual revenue through lack of energy resilience, 30 Oct 2017 3 See, for instance, Mission Critical Power, Can you bank on your back-up power? 16 Aug 2018 4 Siemens Financial Services, ‘Future Savings – Current Gain’, Autumn 2019: www.siemens.co.uk/energyasaservice

drive down their energy use. For instance, building a ‘digital twin’ – an exact virtual replica – of a manufacturing facility, allows solutions to be tailored to each specific site and organisational energy objectives, covering factors such as the demand for electricity, steam, and hot water. Despite the immediate benefits of an integrated energy solution, a substantial number of industrial energy users may be hesitant to risk capital on a non-core part of their business. Expert providers, however, have the knowledge, experience and expertise to offer ‘outcome-based’ financing arrangements which are effectively self-funding and require no up-front capital expenditure. Siemens Financial Services conservatively estimates that UK manufacturers could save £5.6 billion over five years, including £954m in savings for the chemical manufacturing sector, by implementing Energy-as-a-Service solutions.5 Through Energy-as-a-Service arrangements, manufacturers can secure these operational cost reductions without putting pressure on capital resources. Instead, the manufacturer is charged a monthly fee that is structured to effectively deliver a net operational benefit, based on projected energy savings from solutions which optimise their energy use. In this way, manufacturing CFOs make payments based on outcomes – including energy savings, carbon reductions and resilience against disruptive power outages. Prioritising capital investment in energy optimisation is challenging for most manufacturers, competing with many other demands on scarce funds. By being able to access Energy-as-aService solutions, a growing wave of manufacturing CFOs can access new investments right away to reduce their operational costs and improve their competitiveness. On the other hand, if companies simply sit back and wait for the dust to clear, they will miss out on the savings available and lose out to competitors. 5 Siemens Financial Services, ‘Future Savings – Current Gain’, Autumn 2019: www.siemens.co.uk/energyasaservice
