MAKE BOILERHOUSE EFFICIENCY YOUR FOCUS FOR 2019 Are you a plant operator increasingly susceptible to budget constraints and pressure to reduce carbon emissions? Are you a manager or operator needing new ways to increase productivity and boost bottom lines?

A

uthored by steam expert Chris Coleman at Spirax Sarco, the new quick-start guide aims to support you in understanding your plant or energy centre and discovering new ways to improve your energy consumption and boost your business’s bottom line. “By knowing your boilerhouse and understanding the small adjustments that can help support efficiency, operators will be well-equipped to use their boilerhouse to its full potential,” says Chris.

“RO, for example, can remove 98 per cent of all salts, which in turn can reduce potential scaling and boiler blowdown as well as reducing water losses and associated costs for maintenance, water treatment and fuel. Our guide has been created to show operators

how this, along with other simple adjustments, can really help boost boilerhouse efficiency.” Find out how you can enhance boilerhouse efficiency and download the quick-start guide here: sxscom.uk/ boilerhouseefficiencyquickstartguide.

Water companies in England and Wales outperform comparable water sectors in Europe

L

eading international water industry experts Global Water Intelligence examined the quality of water and wastewater utilities in six European countries over the past 28 years, based on six key service performance indicators. They found that the water sector in England and Wales has outperformed those in France, Ireland, Italy and Spain since 1990 in terms of the most important measures on water and sewerage. In five of the six key performance measures – including water quality, customer service and costs – the English and Welsh water sector is either the top performer or the most improved. In the sixth measure – the quality of sewage treatment – the English and Welsh water sector is the second top performer. The report found that the water sector in Germany delivers a broadly similar quality service to that of England and Wales but does so at greater expense – with prices about 12 per cent higher than in England and Wales. The report concludes that there is a strong case for stating that the water system in England and Wales delivers the best value for money of all the utility sectors in the

study, and that the model has driven up standards and reduced overall costs. Commenting on the new study, Water UK Chief Executive Michael Roberts said: “The water industry has come a long way since privatisation in 1989, and customers are now five times less likely to have interrupted water supplies, eight times less likely to suffer sewer flooding, and 100 times less likely to have low water pressure. The business plans that companies have put forward for 2020 to 2025 propose an extra £50 billion of investment, which would see the service improved even further.” The highlights from the draft business plans for the water industry in England were set out in the Manifesto for Water, published on the 3rd of September 2018. The manifesto outlined a 16 per cent cut in leakage, an above 4 per cent real-term reduction in average bills, and a 90 per cent increase in the number of customers receiving financial support from their water company. It also includes a new programme for helping the environment, which will see 8000 km of rivers cleaned and improved. The average household bill is currently around £1 a day for

world-class drinking water, reliable sewerage services and protection of the environment. The Global Water Intelligence’s report, International Comparisons of Water Sector Performance, sets out the six key areas where they felt there was enough data to make meaningful comparisons between the service in the different countries. Those six areas were: • Water compliance – how good is the water that comes out of the taps • The quality of wastewater treatment • Customer service • Non-revenue water – the amount of water ‘lost’ in the system through leakage, faulty meters or unauthorised use • The charge of water and wastewater to customers • The total cost to run the service per person More than 220 sources were examined for the report, which was commissioned by Water UK, and several national agencies and statistics offices were contacted directly, The full report can be found on the GWI website (www.globalwaterintel.com) and the Water UK website (www.water.org.uk)

QUEEN’S QUAY SET FOR SCOTLAND’S FIRST MAJOR WATER SOURCE HEAT PUMP PROJECT

T

he £250m Queen’s Quay regeneration project in Clydebank is set to be the site of one of The UK’s most exciting energy projects, creating Scotland’s first of its kind large-scale water source heat pump scheme to connect to a district heating network which will be delivered by Vital Energi. The ground-breaking scheme will initially see the installation of 5MW of water source heat pumps (2 x 2.5MW) which will take heat from the river Clyde and use it to provide heating and hot water for the surrounding development. The heat generated at the energy centre will be pumped through 2.5km of district heating pipe connecting local homes, businesses and public buildings. Scott Lutton, Operations Manager for Vital Energi says, “This is a very exciting moment in the history of the Scotland’s energy infrastructure. While there have been small open water source heat pumps in the past, this is by far the largest to date. Water source heat pumps are a low-carbon technology which will become more effective in reducing emissions as the grid decarbonises and we hope that, when complete, it will prove an inspiration to other local authorities who want to reduce their carbon emissions.” The £15m energy project will provide heat for the areas homes, businesses and some public buildings including West College Scotland, Clydebank Leisure Centre, the Town Hall and Clydebank Library. The Queen’s Quay development will also see the creation of 1,000 private homes and 200 homes for social rent. Councillor Iain McLaren, Convener of Infrastructure, Regeneration and Economic Development said: “The District Heating Network will have a hugely positive impact

on Queens Quay and Clydebank as a whole and we are delighted to welcome Vital Energi on board to help us deliver it. “Once completed, the network will provide heating and hot water to existing buildings including Clydebank Leisure Centre and the Council office campus as well as serving the new homes. The Council aim to expand the network to include areas of Clydebank and Dalmuir and to address fuel poverty by providing affordable heat to local residents. West Dunbartonshire Council is leading the way with this project and our residents, businesses and the environment will reap the rewards.” Councillor Marie McNair, Vice Convener of Infrastructure, Regeneration and Economic Development, said: “The people of Clydebank will see the benefits of this pioneering project for generations to come. “The system has been designed to not only serve the developments at Queens

Quay but has the potential to serve businesses and houses further afield. “It will also make a major contribution towards the Council’s climate change targets to reduce CO2 emissions.” David Pearson, Director of Star Renewables Energy who are manufacturing the heat pumps said, “As a local company, we’re extremely proud that Scotland’s first major water source heat pump project will not only be delivered in Glasgow, but also manufactured in Glasgow. This project, once again, underlines that Scotland is at the forefront of embracing renewable technologies and driving down carbon emissions.” West Dunbartonshire Council will meet 60% of the cost of the system with the Scottish Government funding £6m through the European Regional Development Fund via the Low Carbon Infrastructure Transition Program (LCITP). www.vitalenergi.co.uk

New framework aims to deliver lowest wholelife leasing costs for public sector bodies

L

ifecycle Management Group, formerly Leaseguard, announces the launch of a new compliant framework for leasing services designed to deliver the lowest whole-life leasing costs for Public Sector bodies, including NHS Trusts. The framework was created in partnership with Cambridge University Hospitals NHS Foundation Trust. The framework differs from conventional leasing frameworks by focussing on achieving the lowest whole-life costs, rather than just the lowest initial cost in isolation. During a compliant, online mini-competition, leasing companies are asked to bid for

6

not only the initial cost of the lease, but also the maximum rentals that will ever be charged under the lease - regardless of how often it is extended. NHS Trusts and Public Bodies will be able to select the weighting they wish between initial and whole-life cost, ensuring the right lease profile is selected to meet their needs. Following a rigorous selection process, the following 12 lessors have been awarded a place on the framework: Arkle Finance, BNP Paribas Leasing Solutions, CHG-MERIDIAN UK, De Lage Landen Leasing, First Asset Finance Capital, GE Capital Equipment

ENERGY MANAGER MAGAZINE • JANUARY 2019

Finance, IBM United Kingdom Financial Services, Shawbrook Bank, Siemens Financial Services, Solutions Asset Finance, TP Leasing and Triple Point Lease Partners. Jonathan Wickens, Commercial Director for Lifecycle Management Group explains: “This framework has been specifically designed with Ts and Cs to ensure our clients receive bids that deliver the lowest wholelife cost, rather than simply the lowest Day 1 cost. This reflects Lifecycle’s philosophy of keeping costs down at every stage of the leasing cycle and we’re thrilled to have so many of the largest lessors on board.”

NEW SOCIAL HOUSING MUST BE ENERGY EFFICIENT AND FIT FOR THE FUTURE A report into England’s housing crisis claims that three million new social houses must be built in the next 20 years, in order to address the problem.

T

he report was authored by 16 independent commissioners, including former Labour leader Ed Miliband and Baroness Syeeda Warsi, and identifies expensive and insecure private renting as a particular barrier to home ownership, as well as a lack of readily available social housing. The government has stated that providing social housing was a priority and that it plans to build 250,000 homes by 2022, including those for social rent. The condition of privately and social rented properties was mentioned in the report and remains a problem

for many tenants. Recently introduced MEES (Minimum Energy Efficiency Standards) legislation in 2018 required private landlords to ensure their properties were a minimum grade E in the knowledge that this will improve the living conditions of those on low incomes, with lower fuel bills and warmer homes. The Decent Homes Standard has driven social housing to lead the way with energy efficiency where the level of poor housing is about half that of the private sector. “Social housing and local authority delivered about 33,000 homes in 2016/17, and therefore an increase to 150,000 a year for 20 years, to achieve the 3 million required, is a massive increase especially when you consider that the whole sector currently delivers approximately 280,000 homes,” explains

EnergyMgr

Martyn Reed, Elmhurst’s Managing Director. “If the recommendation becomes reality, the house builders will need to build approximately 400,000 homes per annum, 42% more than today. What is important is that the mistakes of previous booms are not repeated. These new homes must be built to the highest standards of quality and energy efficiency to ensure that the future tenants don’t become the fuel poor statistics of the future.” www.elmhurstenergy.co.uk

TEAM ENERGY’S ANNUAL CONFERENCE SHINES A LIGHT ON THE FUTURE CHANGES THAT AFFECT THE INDUSTRY A talented line-up of expert speakers joined TEAM at their Energy Management Conference to talk about the challenges of a Changing Energy Landscape.

O

n 20 November, TEAM Energy hosted their annual conference with a theme of the Changing Energy Landscape. Speakers from industry-leading organisations shared their insights on the changing landscape and gave information about how evolving technologies can play a positive role. TEAM’s CEO, Simon Miles, set the scene and National Grid’s Power Responsive Manager, Rhiannon Marsh, talked further about managing demand with available energy sources with their Reforming Balancing Service. Sagnik Murthy from ABB took the conversation onto ideas around energy resilience and the opportunities for generation, solar power and battery storage. KiWi Power’s Growth Strategy and Innovations Champion, Richard Hardy, challenged Business Secretary Greg Clark’s notion that the Energy Trilemma is over. He went on to highlight the benefits of Demand Side Response and how it is an environmentally friendly and cost-effective method of stabilising the National Grid. Tradition Energy took the agenda to a slightly less bright horizon. Craig Mackellar revealed the extent to which wholesale energy prices are rising. He reflected that the 70% loss of UK gas storage has put huge pressure on prices in a market that is made up of one third gas generation. Price volatility is a result of unpredictable wind power and inconsistent storage. He emphasised the need to be interconnected with Europe and hoped that we wouldn’t have a cold January. Shawn Deegan from Yellowfin went on to inspire the delegates about how

data can help energy management and efficiency in organisations. Yellowfin, TEAM’s software partner, worked with TEAM to create an Energy Intelligence module for TEAM’s Sigma software. Shawn Deegan said: “We don’t all see the same pattern in data. Energy Managers have a broad role in organisations - Sigma Energy Intelligence can provide analytics across numerous datasets, help with data storytelling and add context to all of the information that is found in the data” One of the regulatory issues facing the industry was addresses by Gary Shanahan from the Department for Business, Energy and Industrial Strategy (BEIS). He gave a detailed overview of the new Streamlined Energy and Carbon Reporting Strategy. He then went on to address some broader issues in a roundtable discussion. These included the financial qualifications in parallel to ESOS, the future of RHI, how SMEs will be involved, and minimum building ratings in new developments. Later in the day, Verdantix analyst Susan Clarke presented smart building innovation and gave 3 key ideas to make buildings smart. Firstly, boost operational insights from existing data; secondly, utilise IoT through facility sensors; and finally, tap into emerging cost-free solutions. We heard from TEAM’s customers too. Kamar Zaman and Shaun Spencer talked about a shared service approach to energy management at the London Borough of Haringey and Hackney. Simon Chubb, Environmental Manager at Anglia Ruskin University, demonstrated his approach to cost-effective carbon saving and achieving the public sector

emissions reduction pledge by 2020. TEAM’s Service Delivery Director rounded off the day with a summary of changes to the organisation since the takeover, just over a year ago. He also presented a comprehensive 12-month roadmap for TEAM to drive operational efficiency with industry standard processes, and boost data quality with automation, for TEAM’s Bureau service. Graham Paul, Service Delivery Director said: “The bureau service recently recovered eight times more in savings than the cost of the service to one of our customers in one single month. This has been the highest cost savings ratio we’ve ever seen. This has been driven by our improved processes around quality data and knowledge. By evolving the service with our 2019 roadmap, we will continue to increase utility bill recovery success rates for all of our customers.” Another area for TEAM’s focus for 2019 is the continued development of the flagship Sigma software. There will be enhancements to the Sigma EI module which will give customers endless data driven opportunities. There will be data integration and importing enhancements, budgeting improvements and the launch of a tenant billing application. Graham added: “To complement our software and outsourcing services, we have a pool of talented energy consultants. They offer a range of services like DECs, EPCs, Energy Audits, ESOS reporting and RHI, and more. Over the next 12 months we will be raising the profile of this service and growing the consultancy business” This event has been running for 30 years, but this year, TEAM wanted to take delegates on a journey of enlightenment around the changing energy landscape. It was the first time that a range of industry experts shared the stage and presented forward thinking ideas and technologies. This sets a precedent for TEAM who are committed to ensuring their products and services are not only relevant to the needs of their customers, but also are compatible in the ever-evolving energy sector. www.teamenergy.com

WALES DRIVING LOW CARBON VEHICLE AGENDA

A

utomotive giants including Aston Martin, Nissan, Renault, Peugeot and Toyota gathered at Hensol Castle in the Vale of Glamorgan to show Wales’ readiness to maximise on the huge opportunities presented by electric and hydrogen vehicles at the country’s first ever Low Carbon Intelligent Mobility conference. Aston Martin Vehicle Line Director Andy Haslam was there to talk about the company’s new electric vehicles, the Rapide E luxury saloon which will begin manufacturing in nearby St. Athan in the spring, and the Lagonda EV in the coming years. He was joined by Carl Bayliss, Head of Nissan EV, Tony Walker, Managing Director Toyota Motor Europe, and Welsh Government Economy Secretary Ken Skates who talked about the Clean Air Plan for Wales, and reminded delegates that the hydrogen fuel cell was actually invented in Swansea in the

19th century by Welshman William Grove. Aston Martin’s Andy Haslam said: “At Aston Martin we understand emerging technologies and want to maintain our position at the cutting edge of the industry. We are undertaking the most ambitious growth plan of any luxury car manufacturer ever, creating the most accomplished automotive art in the world, based on craftsmanship and artistry. We’re embarking on a new era of electric in Wales, never losing sight of our customers, and who they are likely to be in the future.” The event recognised Welsh innovation with an appearance by the distinctive gullwing Riversimple Rasa, built in Powys, a pioneering hydrogen-powered fuel cell electric vehicle; and news of Cardiff-based Hemmels’ production of the world’s first electric Mercedes-Benz Pagoda, a beautifully crafted rebuild of one of the world’s most desirable classic cars, which goes into

production next summer. The event was chaired by motoring presenter and journalist and passionate advocate of electric vehicles Quentin Willson, and saw Welsh Government outline its policies to support decarbonisation, focussing on the automotive supply chain changes and opportunities as cars go from the internal combustion engine to electric and hydrogen power sources.

Crown Estate Scotland issues first agreement for critical CO2 storage infrastructure

C

rown Estate Scotland has announced that it has signed its first ever lease option for carbon dioxide (CO2) storage. The project, Acorn CCS, which will be based at the St Fergus Gas Terminal on the Aberdeenshire coast, is designed to take advantage of existing oil and gas assets to quickly deliver large scale, cost-effective CO2 transport and storage infrastructure in the Central North Sea. This is the first lease option issued by Crown Estate Scotland for this technology since being established in April 2017 and signals the organisation’s commitment to nurturing innovation and contributing to Scotland’s ambitious climate change targets. An option is a precursor to a full lease. It gives the developer confidence that rights to carry out studies can be granted and will allow other work to progress the proposal. Once new consents are secured, permissions and consents from UK agencies are also required. Carbon capture and storage is a process which captures large quantities of carbon dioxide emissions from industrial processes before it is released into the atmosphere. The CO2 is then transported and stored in suitable underground locations – the rock formations deep below the Central North Sea are internationally recognised for their excellent CO2 storage potential. Colin Palmer, Head of Marine at Crown Estate Scotland, said: “This is a major milestone for the both the industry and

Crown Estate Scotland. Making sure that Scotland can use our natural resources to host this type of cutting-edge technology is something we’re very proud to be a part of, working alongside developers such as Pale Blue Dot. We look forward to working with industry and Government to help unlock the potential of this area.” Alan James, Managing Director of Pale Blue Dot Energy and Acorn CCS Project Leader, said: “Securing this lease option from Crown Estate Scotland is a really important step to help us develop one of the UK’s first CO2 transportation and storage networks. Through Acorn CCS, Scotland can use legacy oil and gas assets to deliver environmental benefits, unlocking CO2 transportation and storage solutions for other carbon capture utilisation and storage (CCUS) projects along the east coast of the UK.” Paul Wheelhouse, Minister for Energy, Connectivity and the Islands welcomed the lease option agreement: “This is a very important step forward for the Acorn Project and Scotland. Scotland’s key CCUS resource is our vast potential for the storage of carbon dioxide (CO2). Scotland’s ‘over-supply’ of offshore geological storage assets, such as can be found in the Central North Sea, presents us, as a nation, with an economic opportunity in future to be at the centre of a hub for the importation and storage of CO2 from Europe. In such a way we can further help address the threat posed by climate change, while also utilising the skills within Scotland’s energy supply chain.”

When combined with critical CCUS infrastructure, Scotland’s excellent geology deep below the Central North Sea has the potential to host around 75% of the UK’s capacity of CO2 emissions, helping meet both UK and Scottish climate change targets. St Fergus Gas Terminal is an active industrial site where around 35% of all the natural gas used in the UK comes onshore, making it an excellent location to construct and operate new industrial facilities (such as hydrogen generation) and to initiate an early CCUS transport and storage hub. As the body responsible for leasing the rights to renewable energy and CO2 storage up to 200 nautical miles from shore, Crown Estate Scotland has an integral role in CCUS, and has been working with industry and Government to help develop the sector in Scotland. www.crownestatescotland.com

OUR ELECTRIC FUTURE

A

s fossil fuel resources are depleted and demand for sustainable energies increase, we are looking to a future of total electrification of energy in homes, industry and transport. This is a world-wide movement, but specifically in the UK, is the National Grid prepared to meet this demand? Renewable energy solutions like solar serve a vital role in meeting future energy requirements, but are the systems currently in place able to monitor and react to the significant changes in demand expected?

Paul Hutchens is CEO of Midlands-based solar specialists, Eco2Solar. He is a board member of the Solar Trade Association (STA), the UK’s leading solar industry voice, and Chairman of the STA’s New Build Working Group which aims to inform governments, councils, house builders and consumers about sustainability in housing. Here, Paul discusses the quickening pace towards electrification of energy the UK, what this shift means for the grid, and how our electric future should ultimately benefit all consumers. 10

SHIFTS TO ELECTRIFICATION Shifts towards total electrification can be seen across buildings and transport, and this movement is gaining pace. Looking first at buildings - the Government’s Clean Growth Strategy released in 20171 recommends “phasing out the installation of high carbon fossil fuel heating in both domestic and non-domestic buildings off the gas grid during the 2020s, starting with new build.” In addition, following recommendations from the Climate Change Committee, there is widespread agreement that heating must be decarbonised in order to meet the UK’s 2050 carbon targets. In terms of transport, all eyes are on electric vehicles (EVs). In 2017, the Government pledged to ban production of new petrol and diesel car sales by 2040 and more recently there have been calls to bring that ban forward to 2032. Several large car manufacturers have announced that they will shortly stop production of vehicles powered solely by internal combustion engine. Volvo will stop next year and Jaguar Land Rover in 2020. Other major manufacturers plan to release high-profile electric models, including Volkswagen who have recently announced plans to handle production of 50 million electric vehicles. Electrification of industry is following suit behind buildings and transport, but the pace of change is slower. However, for buildings and transport the notso-distant future looks to be electric.

INDUSTRY RESPONSE TO ELECTRIFICATION In November 2018, the International Energy Agency reported that the world

ENERGY MANAGER MAGAZINE • JANUARY 2019

has no capacity to absorb new fossil fuel plants. We know that we cannot continue to rely on fossil fuels to generate the electricity required for industry, transport and buildings. This year, electricity generation from coal decreased by 47 per cent from June to August, compared to the same period in 2017, representing just 1.2 per cent of total MPP supply. The gap left needed to be filled by a significant increase in energy production from renewable sources. Indeed, September this year saw a major milestone in the UK power market as for the first time there was more renewables capacity on the grid than fossil fuels. The challenge for the National Grid is how it will balance these different energy sources in order to maintain consistency in supply. The six large energy companies dominating the market are having to show unprecedented agility and flexibility in reacting to changes in sources of energy. At the same time, these companies are being challenged by the emergence of more nimble, small power generators, which can immediately smooth supply of energy supply. These small generators, often positioned in sites that experience power shortages are presenting ‘two-way’ power systems where low carbon energy such as solar are complemented by energy sources like batteries and small, local power stations. These ‘pop-ups’ are increasingly valuable at times of peak demand, especially as we experience more phases of extreme weather.

THE ENERGY GAP? To date, the Office of National Statistics (ONS) reports that demand for electricity has been pretty constant. In the 25 October2 report detailing availability and consumption of electricity, ONS notes “Overall for the three-month period to August 2018, consumption in the industrial sector increased by 0.8 per cent compared to the same period in 2017. Consumption by other final users had a 0.1 per cent increase on the previous year.” In 1997, total consumption of energy in the UK was 321TWh. Twenty years on, in 2017 we consumed just 308TWh. There are many reasons for this including the improved energy efficiency of electrical products, systems and processes. However, this is set to change. In 2017, the National Grid warned that by 2030, electric cars could require 3.58GW of additional capacity, on top of the current peak demand of 60GW. Another


OPINION

estimate suggests that if one in three cars sold in 2035 is electric, the charging of vehicles would account for 3% of the UK’s total electricity demand. The power generation available at present simply won’t meet this increase in demand. Short power outages for homes are disruptive, but nothing compared to the damage that can be done in industry. Pressures on the grid can result in so called ‘brown-outs’: drops in voltage in an electrical power supply system. If this happens in manufacturing plants the results can be devastating, resulting in six figure damages. More and more big businesses are looking for back-ups to their supply. So, what can we do to protect consistency in supply? One answer is likely to be battery storage and smart technology.

SOLAR, SMART TECHNOLOGY AND STORAGE We believe batteries are going to be a big shock absorber for the changes in demand expected across both domestic and industry settings. An Energy Storage report from February 20183 states that “In megawatt-hours, battery energy storage capacities installed in the UK by the end of 2022 will be 50 times what they were as 2017 ended.” As well as solar panels, Eco2Solar install EV charging points and battery storage in new houses. We are preparing for a significant increase in demand over the coming years as individuals and companies aim to be more self-reliant. It is still early days for home batteries, but costs are starting to come down. The space is starting to get interesting, as the big six energy companies race to make their mark in the consumer solar and storage market. Smart technology is key to getting the most out of these storage solutions. In homes, smart energy systems can balance the overall electricity load, using the ‘free’ electricity from the sun to run appliances at times when energy from the Grid is at its highest cost. The ability to store energy at peak times and use it at low peak will present cost benefits to consumers. Investment in out-of-home storage is soaring. Energy Storage News reports 1.

that currently, the largest battery project in the UK stand at 50 MW with Statera’s Pelham Storage project, due to be completed this December. The project, near Bishop’s Stortford in Hertfordshire, has the potential to provide enough power for over 13,000 average UK homes at any time. Drax have also announced plans to build a 200 MW battery storage project in North Yorkshire.

THE COST OF DECENTRALISATION Taking energy demand out of the National Grid and localising it presents some interesting challenges to the utilities sector. Less than 40% of an energy bill is the wholesale cost of the energy, the remaining 60+% covers network costs, operating costs etc. As the sources of electricity production change, infrastructure changes are needed, and the cost of electricity distribution will increase. This means bigger bills. As bills increase, more consumers and businesses will choose to capture and store their own electricity, effectively becoming ‘off grid’. This creates something of a spiral effect in the utilities market. Investment in the grid is necessary to ensure supply consistency, but each user that comes off the grid reduces the grid’s ability to absorb these costs – and the increased costs will be passed on in increased energy bills for those still needing connection to the Grid. This dynamic is going to be very difficult to stop once it builds momentum and creates significant problems for the utilities sector. Self-sufficiency in energy generation is welcomed but the safety net of a centralised electricity resource is also important.

WHAT THIS MEANS FOR CUSTOMERS Unlike fossil fuels, electricity can be captured and stored at home through domestic solar and battery systems. As climate change becomes an increasing concern for end users, it is anticipated that this will further influence government policy and regulation and accelerate adoption of sustainable technologies throughout homes industry and transport.

The recent influx of smaller energy companies is disrupting the market. There are now 60+ energy suppliers in the UK market – a fourfold increase compared to a decade ago. These energy providers have been credited with opening up competition in the energy space, leading to better deals for customers and much-improved switching rates. More than half a million customers switched to different electricity suppliers in September 2018: the highest number of switches in a month so far this year. And start-up energy companies such as Octopus and OVO energy are offering 100% green electricity, allowing consumers to choose energy solutions which are aligned to their environmental concerns. Peer-to-peer energy trading is also a model that is set to benefit end users. The model which is still in development, will allow for producers and consumers to trade electricity directly, rather than selling to, and buying from the grid. In addition, the advancement of battery technology and cheaper batteries is going to allow more consumers and businesses to install more effective, smarter battery systems on their premises. Just think what the batteries in laptops were like 10 years ago. Battery units are now cheaper, lighter and more efficient. These great advances in battery technology are likely to benefit consumers in and out of home. This is all good news for the consumer. The mix of new services and business models such as peer-to-peer energy trading, home energy storage, smart tariffs should drive down bills. Electrification is gaining pace, and this represents an opportunity for significant reductions in energy bills for consumers. The process is not going to be without challenges, and it is going to be interesting to see which of the energy companies thrive and which fail to keep the pace. In the meantime, focus on off-grid energy solutions like solar greatens, and we’re already seeing increased interest in the battery storage solutions. We are looking forward to working with more house builders as the shift towards electrification quickens and demand for sustainable solutions continues. www.eco2solar.co.uk 2022 | Energy Storage News.

OPINION

HEAT: DETANGLING DECARBONISATION Kevin Stickney, Managing Director at Erda Energy, argues clearer thinking is needed to meet decarbonisation goals in the heating sector.

I

f I asked you: should we get the train or drive? Take the motorway or the B-roads? Will the traffic be bad? You’d probably reply: well, where is it you’re going exactly? Because trying to plan a journey without an idea of destination is doomed to fail. Yet that’s precisely where we’ve found ourselves in the debate around decarbonising heat in the UK. We know some things for certain: 2050 is only 32 years away, by which time we need 100 per cent, total decarbonisation of heat to meet our legally and morally binding climate commitments. We also know that the two frontrunner ‘big ideas’ are electrification and greening the gas network with hydrogen. But that’s where clarity stops and we’ve jumped immediately to internecine squabbles about the costs and technical challenges of each. We’re fretting about traffic and lane closures before deciding where we’re headed. That’s tangled thinking. Step one is to figure out which option offers the most credible path to complete decarbonisation (and can start having an effect immediately). Step two is to then address the challenges. Who picks where they’re going because the roads are clear?

path to zero carbon power. That means immediate carbon savings for electrified heat that will only grow as the grid greens. Electrolysis, by contrast, is at least a generation away at a commercially viable scale. Nor will it appear spontaneously: most likely it will only take off if there is already an extensive hydrogen network, meaning in the meantime we’d need to rely on steam methane reforming (SMR), which releases carbon which would need to be captured by carbon capture and sequestration (CCS). That technology that doesn’t currently exist at the required commercial scale either. Bloomberg New Energy Finance’s Michael Liebreich recently wrote that “anyone promoting SMR-based hydrogen as a climate solution deserves their own circle of hell.” Both options fail on beginning to deliver complete decarbonisation now. It could take 20-30 years to see these technologies deployed at the necessary scale. We can’t wait a generation to start serious decarbonisation of heat.

THE CART PULLING THE HORSE

So: electrification offers the only currently credible path to zero carbon heating. With that as a starting point – the horse firmly in front of the cart – what are the challenges that this approach faces and are they surmountable? What does the journey look like? There is one overarching argument against electrification of heat that is put forward time and time again: that peak heat demand in the UK is roughly six times (‘6x’) peak power demand, and that the volume of extra generation required and the strain on the distribution grid makes it unfeasible. Thirty extra Hinkley C’s is one questionable figure bandied about. But that ‘6x’ argument doesn’t stack up. First, we have the fact that as a country we have been incredibly lazy when it comes to controlling heat. Cheap, plentiful North Sea gas has seen the UK trundle along with some of the most inefficient building stock in Europe. There are big, easy wins to be had by tightening building regulations to make our homes and businesses less wasteful (both Energy UK and the UK Green

Fretting about implementation challenges before assessing decarbonisation potential is putting the cart before the horse. How can we reverse that? We can start with some basic questions. First, which technologies can deliver truly zero carbon heat and second, which can start to do so now? To the first question, we can answer electrified heat or electrolysis-generated hydrogen powered by zero-carbon generation. To the second though, the only answer is electrification, where various technologies have existed for decades, such as air and ground source heat pumps, and are getting better all the time. Moreover, they rely on electricity to generate heat – recognisably the one area where we have achieved significant success in decarbonisation. Average grid carbon intensity stood at an estimated 254 tonnes of carbon emitted per GWh produced by 2016, down from 456 in 2010. What’s more, there is a credible (though not easy)

RUMOURS OF IMPOSSIBILITY, GREATLY EXAGGERATED

ENERGY MANAGER MAGAZINE • JANUARY 2019

Building Council recently called again for action on this point). Reinstating the zero carbon homes policy that was scrapped in 2015 would be a start, as would upping the ambition on the new ECO consultation. Then look at the opportunity presented by smart heating controls such as Hive and Nest. We are woeful at controlling heat in the UK but software will eat inefficiency and smartphone apps will boost user engagement to help reduce peak demand. Coupled with better insulated, less wasteful homes, we could see that ‘six times’ gap start to narrow pretty quickly (in fact, we already are). These are no-regrets courses of action that need to happen now. Having reduced heating demand, we can start to think about how electrification fares at meeting what remains. Would it really create just too much power demand? It’s worth pointing out that we don’t reliably measure heat demand the same way we do for electricity. Usually we use gas demand as a proxy, so interlinked they are. But gas is never 100 per cent efficient, there is always wasted energy. So we may well find that final energy demand is a little less dramatic than we think. Second, electrification and thermal storage technologies open up possibilities to time-shift demand, smoothing the ‘6x’ peaks. This could be as simple as filling a hot water tank when power is plentiful overnight, or as advanced as using geo-exchange to store heat in the ground over summer to be used in winter. Electric systems can also participate in demand response programmes, which are increasingly popular at the commercial and industrial level and promise great opportunity at the domestic one. So, let’s start right now by getting a better understanding of actual heat demand and reducing it – that first part of the journey is the same regardless of the destination. Then let’s get clear about where we’re headed and start planning how to get there – not the other way around. It’s clear to me that electrification is the most viable route to truly zero-carbon heat and has the advantage that we have the proven technology to start right now. There are legitimate challenges – notably around the peakiness argument – but they have been shown to be overblown. In any case though, we need to detangle our thinking and start making decisions now. Climate change won’t wait. So, where to? www.erdaenergy.com


OPINION

NEW ENERGY TECHNOLOGY COULD SAVE BRITISH HOSPITALITY AND LEISURE SECTOR £310M-A-YEAR

T

he report Distributed Energy: Powering the future of hospitality and leisure, found that if just 50% of businesses in the sector adopted new energy technology it would boost UK economic growth by £3.7bn GVA (Gross Value Added) and support 50,000 jobs. The hospitality and leisure sector is the UK’s third largest employer and spends more than £1.3bn a year on energy. Businesses have been challenged to improve their energy productivity by 20% by 2030, as set out by the Government’s Clean Growth Strategy. Alan Barlow, UK and Ireland Director at Centrica Business Solutions, said: “New energy technology has the potential to drive growth, increase efficiency and help give businesses in the hospitality and leisure sector a competitive advantage. “Investing in this area doesn’t just make sense financially. Businesses are increasingly harnessing the sustainability benefits of low-carbon energy technology to attract and retain growing numbers of environmentally-savvy consumers.” The research suggests that savings could be achieved by adopting distributed energy technology such as efficient heating and lighting, solar, Combined Heat and Power (CHP) and battery storage. New energy monitoring technology can also help to identify inefficient equipment and processes.

CARBON EMISSIONS SAVINGS FOR THE HOSPITALITY AND LEISURE SECTOR The report follows the publication of Centrica’s ‘Powering sustainability’ report in October, which found that the hospitality and leisure sector could reduce its annual carbon emissions by 14% through the adoption of new energy technology. Centrica calculated that, if just half of hospitality and leisure businesses in the UK adopted distributed energy technology, the sector could reduce emissions by the equivalent of 1.3 million tonnes of carbon dioxide a

This is equal to the annual carbon emissions associated with the energy use of 421,000 homes, or equivalent to the entire housing stock of Norfolk.

CASE STUDY: ALTON TOWERS RESORT An example of a hospitality business realising the benefits of new energy technology is the 550-acre Alton Towers Resort. It is home to four hotels, a conference centre, more than a dozen restaurants and Europe’s largest waterpark. The hotels alone can accommodate 2,500 guests and 400 staff.

The facilities team must ensure power is supplied to all of these different buildings as well as provide heat for the 1,000m³ of water in the waterpark. Centrica Business Solutions installed a combined heat and power unit (CHP) at the resort capable of generating up to 850kWh of electricity. CHP is a form of on-site energy generation that uses the heat by-product of electricity generation so that it can be put to use – in this case, to maintain water temperature in the park. Meeting these two needs from one source results in an annual saving on energy costs for Alton Towers of 12% a year. www.centrica.com/economicfuture.

ENERGY MANAGEMENT

HOW ADDRESSING DATA LATENCY COULD HEAT AND COOL OUR HOMES AND BUSINESSES Kevin Stickney, Managing Director, Erda Energy.

T

he pace of change in how we produce and consume data is accelerating. As our world becomes ever more interconnected, we must adapt and plan for the needs of tomorrow – as if it were yesterday if we want to keep up. Another major change we face as a society is the shift to a world driven by renewables in the face of climate change. Mostly these shifts are considered in isolation, but a more coordinated approach reveals some useful intersections.

NO TIME FOR BUFFERING The premise of the classic cat video is changing, where once we may have required a few milliseconds to buffer and then be on our way, the cat now requires a constant, real-time connection for us to interact with him and move through his augmented reality space. Cats in virtual reality are perhaps a fairly low priority in terms of ensuring seamless data upload and download, yet the internet of things, and emergency services, are not. Latency – the measure of how long it takes to retrieve data from a server – is a critical issue when autonomous vehicles must make life-changing decisions instantly. It’s an important one in lots of other applications too; nobody will be interested in augmented reality if it cannot run as smoothly as real life or does not meet our visual quality requirements. The distance between user and server is a key factor in determining the level of latency: roughly 1 millisecond is added for every 60 miles1 the data must travel. To reduce latency and support the changing needs of data we must bring data centers closer to their users. In the past, many data centers were located in remote areas, where real estate is cheaper, and the power grid less strained, but recent technological developments open up new opportunities to create 1 https://www.pingman.com/kb/42

14

synergies between data centers and the communities in which they serve. This brings us neatly onto district energy, heating and cooling. Why burn a fossil fuel when we can capture energy instead? District energy is a network of hot and cold-water pipes that can be used to heat and cool buildings, whether that be businesses, homes, universities, shopping centers etc. In more traditional set ups the thermal energy is produced by boilers, combined heat and power or absorption chillers, all of which rely on using vast amounts of energy to generate heating and cooling. Yet, waste heat is all around us, seeping out of everyday infrastructures such as sewers, electricity substations, subways, buildings and EV charging stations as well as being stored in the ground around us and water sources including rivers. So, it doesn’t make sense to expend lots of new, fossil-fuel based energy to generate heat when we could just capture it instead. The opportunity for data centers The process of “data” involves converting masses of electricity into massive amounts of “heat” – which the data needs to get rid of. Yet the same heat that is a nuisance for data centers can be a valuable resource for the community. By looking beyond their own doors to collaborate with the community that they serve with all of their data needs and manage their thermal load collectively, everyone stands to benefit from more affordable energy bills. For the data center it could be an additional

ENERGY MANAGER MAGAZINE • JANUARY 2019

source of revenue, and for the community it’s a reliable source of low carbon, low cost heat. Once you’ve looked at all the economic options for capturing waste heat in your local area, geo-exchange can provide the rest. Using deep boreholes to take advantage of the consistent ambient temperature of the earth, geo-exchange can provide both heating in winter and cooling in summer. The system uses electricity as its only input and can ‘timeshift’ energy by storing or drawing excess heat from the ground on either a shortterm (hour by hour) or long-term (season by season) basis. In essence it can ensure thermal loads are matched at all times, providing the same level of system flexibility as any other thermal source. A whole-systems approach Taking a local approach creates a different way of thinking about energy. It pushes us to take a holistic view of the system around us, not just thinking about energy, but about transport, data, infrastructure and behaviour, so that we can be smarter in meeting the needs of our businesses and communities. But taking a local approach does not mean that the benefits are only local, there are systemwide benefits too. Capturing waste heat and putting


ENERGY MANAGEMENT

it to use reduces our consumption of fossil fuels. Creating an integrated, local grid heightens resilience, particularly against extreme weather and unplanned outages, and by being thermally efficient we can also increase energy productivity. As our data demand grows exponentially, we must stop to think about how we power this need. The amount of data that we need to process to keep up with the evolution of the internet of things cannot also see us exponentially increase power too – particularly as we strive to meet carbon and climate targets. So how can a data center operator squeeze more out of the energy that they use? How can we process more kilobytes per kilowatt hour? The likes of Facebook and Amazon are already committing to power purchase agreements for renewable electricity, but the next move needs to be valuing waste heat properly. It’s a resource that can be recaptured and reused several times over and help to significantly improve energy productivity. After big weather events we often see reports of energy infrastructure being damaged and becoming unavailable, or running at a reduced capacity. Whereas keeping heat or cooling in the ground is virtually impossible to destroy, and with much of the infrastructure below ground, it is a lower risk of damage. And in terms of disaster response, emergency responders increasingly depend on the data network - having critical infrastructure at full service, whether that be hospitals, fire and police stations or the data network for those responders to coordinate across, is lifesaving stuff. While many of these facilities will have backup generators for power, thermal provision is often overlooked. In a hospital where controlling the environment is critically important, a reliable, resilient system is key. So, as we step into this new world of augmented reality and the internet of things, it’s important we take a moment to explore the new opportunities that this creates. And as urbanisation continues it will be especially important for those cities that are already struggling to meet the needs of their inhabitants. If we encourage everyone to share energy in this way, use can be optimised – meaning less resources required all round. www.erdaenergy.com

PRIVA BMS HELPS PRESERVE HISTORIC HQ OF NATIONAL CENTRE FOR WRITING

T

he National Centre for Writing, which has just completed a £2 million extension and refurbishment project at its headquarters in Norwich, called upon the capabilities of the latest Priva BMS (building management system) as a vital part of the upgrade. By installing state-of-the-art Priva Blue ID technology to monitor and control the internal climate, the organisation hopes to ensure that the building’s fabric, which includes ancient timber beams, is preserved in an optimum way. Since 2015, the National Centre for Writing has been based at Dragon Hall, a Grade I listed, 15th century medieval trading hall of significant historic interest. In such a building, factors like humidity can have an extremely detrimental and compromising effect on the internal structure. With this fact in mind, and the knowledge that the building’s existing BMS was reaching the end of its life and becoming unreliable, the decision was taken to invest in Priva technology. Although Dragon Hall, the Great Hall of which was built in 1430, is a befitting home for such a prestigious organisation as the National Centre for Writing, there is a constant need to ensure that the building is both fit for purpose and properly preserved for the future. With this in mind, permission was sought to upgrade the property. Clearly, as part of such a major innovation, the opportunity arose to optimise the climate control for both occupant comfort and building preservation. The existing building was served with an ageing BMS prone to reliability issues. To address the situation, Norwich-based Electrical and Mechanical

Controls Ltd (EMC), a long-standing Priva partner, was appointed to the project. This time around, however, the list of demands was much longer as it involved the renovation of a structure that is one of the famed ‘Norwich 12’ iconic buildings. Dragon Hall, which is renowned for its spectacular timber crown-post roof and intricately carved dragon, is symbolic of Norwich as a city of historic national importance. The existing BMS, as well as being unreliable, suffered from both poor usability and operability, being described as “fiddly and not user friendly”. Upgrading the system in terms of better control and easier maintenance, was thus a priority. At all stages of the project, EMC needed to be mindful in terms of minimising any disruption to building’s day-to-day operations. As well as hosting the National Centre for Writing, an organisation called the Dragon Hall Heritage Volunteers act as tour guides to the building, which is also home to a museum. Couple this task with the priority of not compromising the building’s structural fabric, and the size of the challenge is plain to see. The historical significance of Dragon Hall cannot be overstated; although the Great Hall on the first floor was built in the 15th century, some parts of the site are much older. In fact, archaeological research shows evidence of a Saxon building beneath the hall that was erected around the year 1000. The upgraded and extended Dragon Hall was opened in June 2018, and the end user is reporting complete satisfaction with the new BMS. Moving forward, more benefits are anticipated. www.priva.co.uk

MONITORING & METERING

AN INSPIRED WAY TO SOLVE YOUR ENERGY MONITORING PROBLEMS

W

e all know that we need to measure and monitor our energy use, and for a variety of reasons. Rising energy costs are more and more justifying the savings that can be made by identifying inefficient equipment and out of hours use. Then there is our own desire to improve our green credentials by reducing emissions, along with edicts like the imminent Streamlined Energy and Carbon Reporting (SECR) regulations, to make sure we do. Studies by the Carbon Trust show savings of up to 20% can be achieved through energy efficiency measures. Monitoring energy used 24 hours a day can identify out of hours usage, which accounts for 46% of energy consumption in UK SME’s according to a recent British gas smart meter survey. Office equipment plays a significant role in the energy consumption of a small business, and turning off nonessential equipment at the end of the day can achieve savings of 12%.

16

Office equipment left on standby during Bank Holidays and weekends will cost the average SME up to £6,000 per year. Up to 40% of a building’s electricity use is accounted for by lighting, and installation of occupancy sensors, daylight sensors or photocells, and replacing existing lighting with LED modules, can reduce electricity costs by between 30% and 80%. Once you decide to take the plunge to look at your electrical usage you would be best served to hire or buy a power and energy logger (PEL). This

ENERGY MANAGER MAGAZINE • JANUARY 2019

will allow you to move it around the facility, monitoring electricity usage at various locations, and enable you to identify and measure the savings to be made. Only by monitoring and measuring will before and after energy use figures become available to accurately calculate these savings and justify any necessary expenditure. There is also good argument to say that any decent sized business should then continuously measure its energy usage with a permanently installed system. It can then chart consumption


over time, identifying out of hours and seasonal usage, and monitor Power Factor degradation and Power Quality parameters such as harmonics. Modern installations may already have such monitoring systems fitted, but there are often issues with retrofitting to an older installation. Not only that but the cost of the installation of a permanent system in equipment and labour, and the associated disruption, including switching off the power and cutting holes in panels to fit meters, etc., make it a somewhat daunting prospect. Thankfully nowadays you can purchase a PEL to perform whatever logging you need around the installation, and then semipermanently and non-intrusively install it in the distribution cabinet for continuous monitoring. Modern PELs are designed to be so slim that they can be magnetically stuck to the inside of the cabinet door, or another convenient space, and left semi-permanently installed, while being safely locked away. Rogowski coil current sensors, and magnetic voltage probes that can simply

be stuck onto MCB screw heads, or permanently wired if preferred, enable an entirely non-intrusive connection to the supply. There’s no need for a competent trained electrician to have to switch off the facilities power while the PEL is being installed. These PELs can be selfpowered from the installation to which they are connected, and plugged into the computer network for remote monitoring. Or just interrogated regularly through a tablet or smartphone.

Quite simply, you could deploy a PEL around the site when you want to monitor certain pieces of equipment or departments, and then literally stick it in back in the distribution cabinet afterwards, and monitor on an ongoing basis. As and when you want to use it somewhere else, you can move it, use it, put it back again, and so on. Probably the most cost-effective way to obtain a temporary and permanent logging solution to reduce your energy use. www.chauvin-arnoux.co.uk

MONITORING & METERING

AN ACCURATE CURRENT METER IN EVERY BEDROOM AND HOT WATER TANK Prefect Controls have introduced a new feature for their PrefectIrus product – the integration of an accurate current meter that monitors energy use in each room throughout multioccupancy buildings such as student accommodation.

U

ntil now, managers have calculated energy use based on power rating multiplied by length of time a device is estimated to be active. However, fluctuating voltage and imprecise predictions of ‘on-times’ can make these estimates wildly inaccurate. The new PU3 from Prefect comes with iACM (Integrated Accurate Current Metering) as standard, logging the current only when a heater is operational. This data is then transmitted via the buildings wiring system to the central controller where it is recalled for estimation of seasonal energy usage. As well as monitoring heaters in bedrooms, the feature also notifies managers if there is a problem with hot water tanks. Usually a problem

is only evident when both elements fail and water isn’t being heated. With accurate metering, if one element fails, the drop in current immediately identifies the problem - meaning efficiency can be restored. Glen Golding, Prefect Controls MD, said “This development means accurate usage can be calculated so that better purchasing of energy will lead to greater savings for organisations providing multi-occupancy accommodation.” PrefectIrus is currently in more than 20,000 bedrooms and continuous development makes it an invaluable product to ensure efficient use of energy across Britain’s university accommodation estate.

ENERGY SUPPLY

SOLVING THE MYSTERY OF UNIDENTIFIED GAS Steve Mulinganie, Regulatory Manager at Gazprom Energy.

O

ver 4 per cent of the UK’s gas ‘goes missing’ every year, costing the industry over £100 million. This unidentified gas (UIG) is delivered to the grid, but not attributed directly to customers due to a number of factors including metering inaccuracies, gas theft or leakages. Although the gas is not directly attributed it still needs to be paid for. While historically UIG was less visible, new systems implemented from June 2017 has meant increased transparency of these costs for customers.

WHY AND HOW DID THE WAY UIG IS CALCULATED CHANGE? On 1st June 2017, Xoserve’s IT systems for gas settlement and supply point administration were replaced as part of Project Nexus, changing the way UIG is calculated. This increased the industry’s ability to track UIG on an ongoing basis and attribute it proportionately to shippers. In turn, consumers have faced increased risk premiums and pass-through costs due to increased levels and volatility of unidentified gas. Previously, UIG was determined

by an independent expert who calculated an energy value which was set in advance and then recovered from the market. This meant both the scale and volatility was predictable. Project Nexus’ new IT systems introduced the ability to determine UIG across all supply points. This allows UIG to be estimated on a daily basis using a formula that subtracts leakage (shrinkage), daily (actual) and non-daily (estimated) meter readings from the amount of gas recorded as entering the network. UIG is then spread across all meters using factors set by the industry experts. Importantly as actual meter readings are received, adjustments are made to the allocation, meaning prices are constantly changing. It’s important to understand that this effectively creates both permanent UIG and temporary UIG as a result of estimation. If the estimation process is inaccurate then the value of UIG will be subject to correction.

WHAT IMPACT HAS BEEN FELT? While in theory the new system should be fairer, it has resulted in far higher than expected levels of UIG, averaging 4.65 per cent of total gas on the grid. In contrast, prior to the changes, the volume of unidentified gas was estimated to be between 1 and 1.3 per cent. These levels have become increasingly volatile, quickly swinging from as much as 25 per cent of the total

demand to less than zero. This has become a particular issue during periods of peak demand such as the colder winter months.

HOW HAS THE MARKET RESPONDED? Since these changes came into force, the industry has put forward proposals for Ofgem to revert to the pre-Project Nexus arrangement, which Ofgem has since rejected. Following this, last year, Ofgem approved the creation of a taskforce that aims to tackle the ongoing issues around the allocation of UIG. Ofgem hopes the new taskforce will help the industry to identify and address the root causes of the unexpected volatility.

WHAT DOES THE FUTURE HOLD? The ongoing rollout of smart and advanced meters, has the potential to support the more accurate allocation of UIG. Being able to provide more accurate readings allows the market to gain a greater understanding of the causes of UIG and be less reliant on estimation. Proposals are still being presented to industry bodies within the market for review and the energy industry continues to work to find a solution to the issue. The energy market is a fast moving, ever evolving industry and 2019 is a new year, which can only mean continued changes, constant developments and new regulations. Businesses should stay abreast of any developments and contact their energy suppliers if they feel as though they are adversely affected. www.gazprom.com

NEWS & MOTORS DRIVES

THRIVING UNDER PRESSURE: THE VPI TREATMENT FOR MOTOR WINDINGS Electric motors, although relied upon for their durability in aggressive operating environments, can be surprisingly delicate. David Bevilacqua, Technical Manager for HV Motors and Coils at ERIKS UK & Ireland, explains how opting for Vacuum Pressure Impregnation (VPI) could be the solution to ensure they are protected and perform as they should. 20

I

n aggressive environments where electric motors are regularly exposed to high temperatures alongside wet and corrosive substances, the insulation materials they are constructed from can quickly degrade over time. Therefore, in order to keep these critical components operational, contamination and moisture ingress should be prevented where possible. Both contamination and moisture can create tracking paths through the winding, allowing electrical leakage to earth and, eventually, a motor to trip. For a motor to stand the test of time then, the insulation resistance must be maintained. Thankfully though, there are some simple solutions whereby motors can be treated to resist moisture. These include dipping the winding in a polyester or epoxy resin to create a moisture-resistant coating, or a process called Vacuum Pressure Impregnation (VPI). Our experience suggests the latter is the most effective.

ENERGY MANAGER MAGAZINE • JANUARY 2019

PRESSURING PERFORMANCE VPI works by forcing resin into the depths of a winding using vacuum and pressure, in order to fill air pockets which, if left unresolved, can make a motor winding far more susceptible to future wear and tear. This method also binds together any loose lamination in the core: not only helping to keep moisture out but


DRIVES & MOTORS NEWS

also enhancing the winding’s mechanical strength and heat dissipation properties. The advantage of VPI over dipping is that moisture resistance is integrated into the winding structure itself, rather than simply forming an outer coating. Although VPI has been an available solution for many years, many treatments use resins optimised for low-cost processing rather than performance. Instead, it is best to opt for a more effective 100% solid epoxy resin which is optimised for performance and protection.

VPI AND BEYOND Although VPI is an important technique for improving the longevity of a motor, it isn’t a one-size-fits-all solution and, in some scenarios, additional measures will be required to ensure a motor’s protection, such as a complete rewind. In this situation, it is best to consult the experts who will be able to advise on the best plan of action. For example, if a motor is in good condition apart from its porosity and moisture absorption, then VPI alone has

the potential to increase its service life by several years. If, however, the winding has deteriorated too far, often the best course of action is a complete rewind using highly absorbent VPI-compatible material, followed by the VPI process. The compatible material will increase the uptake of the epoxy resin to help form a solid, homogenous mass, providing maximum moisture resistance.

THE BIGGER PICTURE With any equipment failure, it is important to look at the bigger picture in order to determine the most appropriate solution. For example, ERIKS was involved in a project where a certain type of AC freight train’s traction motors were proving unreliable due to the damp and dirty conditions they were operating in. In this scenario, it would have been easy to recommend VPI as a quick-fix solution as, after all, the damp and dirty operating conditions suggested that contaminant and moisture ingress to the motor were the main problems. However, after further investigation we were able to determine that the failure mode was

due to a breakdown between phases on the stator winding connections. Realising that VPI would only partly solve the problem, we not only stripped the connection rings and reinsulated them using VPI, but also redesigned them. The original high temperature silicone insulation system within the coils was retained, to provide highertemperature protection where it was most needed. Meanwhile, the redesigned rings were sealed with Class H 180°C epoxy VPI, providing greater protection against environmental conditions. The result was a complete elimination of the motor failure mode, and an ongoing programme to modify all the customer’s other traction motors in the same way. Ultimately, electric motors should be durable and relied upon to stand the test of time, even in the most aggressive operating environments. Although VPI alone won’t always be the most suitable solution, it should certainly be considered as a first option when it comes to repairing damaged motor windings to improve their longevity. https://eriks.co.uk/en/

UNIVERSITY HALVES ENERGY USE AT ITS STUDENT ACCOMMODATION BUILDINGS WITH REMEHA BOILERS

Aberystwyth University has slashed gas consumption and costs by 50% at its student accommodation buildings since replacing ageing boilers with high efficiency Remeha Quinta Pro condensing boilers.

H

alls of residence have a high demand for heating and hot water, so it’s important that the heating system works as efficiently and effectively as possible to reduce energy costs and environmental impact. When the time came to replace the existing ageing boilers in the four plant rooms serving the Penglais student accommodation buildings, reliability was a key requirement for the University. Further considerations were the need to complete the project in a fixed fourweek period and standardisation of the heating equipment for easier future operation, maintenance and servicing. Heating engineers Aber Heating Ltd have been working with the University for over a decade, during which time they have gradually been replacing all the boilers to Remeha products. To meet the heat demand at the halls of residence, Sion Jenkins, Project Manager at Aber Heating, installed two Quinta Pro 65 condensing boilers in each plant room. Sion commented: “We recommend Remeha heating products for their quality and reliability. The boilers have been designed for improved ease of installation, which helped us to meet the challenging schedule on this project. And, importantly for whole life costing and long-term operational savings, spare parts and ease of servicing have also been addressed. The Quinta Pros are lovely to work on – you can’t fault them.”

Condensing boilers are the most efficient of all boiler technologies. Remeha’s Quinta Pro 65 condensing boilers deliver gross seasonal efficiencies of up to 98% and ultra-low NOx emissions, ensuring greater reliability and improved comfort levels. Completing the energy-efficient system design in each of the four Penglais plantrooms is an equally energyefficient Andrews Water Heaters MAXXFlo 90/200 condensing water heater. With recovery rates of up to 1,920 litres of hot water per hour, this provides a

ENERGY MANAGER MAGAZINE • JANUARY 2019

continuous supply of instantaneous hot water to satisfy the hot water demand. With all four boiler rooms refurbished within the tight timeframe, the heating upgrade at Penglais Campus has been an unqualified success. “The project went well,” said Sion. “The students are benefiting from the more effective and reliable heating and hot water service, while energy data from the University has revealed a 50% reduction in annual gas consumption and costs in the buildings served by the new Remeha boilers.” www.remeha.co.uk/

COUNCIL INSTALLS REMEHA CHP AT LEISURE CENTRE TO REDUCE ENERGY COSTS AND CARBON FOOTPRINT

E

den District Council (EDC) has selected a Remeha R-Gen 20/44kWe Combined Heat and Power (CHP) unit to provide low carbon heat and power at Penrith Leisure Centre, located in the heart of Eden. The move comes as part of EDC’s wider commitments to reduce its energy consumption and environmental impact across its estates. In addition to a state-of-the-art gym, studios and a sports hall, Penrith Leisure Centre boasts a 25-metre swimming pool and 13-metre studio pool. Open almost every day of the year, the site has a high, constant demand for heat and power. Previously the Centre had been heated by a turbine CHP, boilers and water heaters. However, due to oversizing, the CHP had failed to achieve the anticipated performance levels and savings benefits. When the failing plant came to the end of its lifetime, EDC’s requirements were to implement a new high-efficiency renewable or low-carbon solution that would improve the Centre’s energy performance and reduce emissions. Increasing operational efficiency was a further consideration for GLL who manage the leisure complex. Mechanical & Electrical engineers Thomas Armstrong recommended replacing the old plant with a new ultra-low NOx condensing CHP unit operating in conjunction with high efficiency condensing boilers. CHP is effectively a super-efficient micro power station that generates heat and power in a single process at the point of use. Instead of rejecting the ‘waste’ heat to atmosphere like traditional power stations, the heat generated by CHP can be re-used to provide high grade heating and hot water. Sites with year-round requirements for electricity and heat are well suited to using CHP. Swimming pools provide the perfect circumstances for this, making it a particularly effective solution for Penrith Leisure Centre. Stephen Clarkson at Thomas Armstrong was familiar with Remeha’s R-Gen CHP range and its

reputation for high performance at other leisure centres, supported by Remeha’s dedicated CHP team. The design scoped by Thomas Armstrong identified a Remeha 20/44kW ultra-low NOx condensing CHP unit working in conjunction with three Remeha Gas 310 Eco Pro high-efficiency condensing boilers. The R-Gen condensing CHP unit can achieve total gross efficiencies of up to 98.7%, meeting EDC’s requirement for optimum efficiency. As such, it is capable of reducing primary energy costs by around 40% compared with traditional heating plant and electricity supplied solely from the grid. Accurate sizing of the CHP unit was critical to maximise the energy and carbon saving benefits. Remeha’s CHP team worked closely with Thomas Armstrong throughout the project. “The Remeha team are extremely knowledgeable about CHP technology and have provided valuable advice and support at every stage,” said Stephen. “At the initial design stage and during the installation, they have been there to offer help and backup.” The CHP system was commissioned by Remeha and has been operating non-stop ever since.

“The Remeha R-Gen CHP produces 44kW of heat per hour and it’s been using it all, even in the summer months, at Penrith Leisure Centre,” Stephen continued. “It’s heating the constant temperature circuit, feeding radiators, fan convectors, air handling units, providing hot water for shower facilities and, of course, heating the two swimming pools.” The Remeha R-Gen CHP is closely monitored by Remeha’s remote monitoring service. A Remeha CHP service plan is also in place which includes inspections at regular intervals – typically at 6,000 CHP operating hours for a 20kWe unit. Remeha is also providing the Council with monthly reports for evaluation purposes. “The CHP installation went smoothly,” said Doug Huggon, Leisure & Community Services Manager at EDC. “We’re pleased to see that the CHP is running well, meeting our requirement for low carbon heat and power and we’re anticipating significant energy cost savings in the months ahead.” Remeha’s CHP range spans 5.5kWe to 150kWe.

RINNAI SOLO FOR LOW NOX CONTINUOUS FLOW ON DEMAND HOT WATER…… BUT WITH A STORE…. Rinnai Infinity Solo condensing and low NOx water heater is said to be the first of its kind in the UK to combine the advanced technology of low NOx wall mounted continuous flow water heaters with a stainless steel storage cylinder, all in one compact footprint.

T

he design parameters of this product allow specifiers, designers, installers and engineers to benefit from unique Rinnai technology in applications it was once not previously possible. For instance, the Infinity Solo features both 35kW and 54kW sized appliances, ensuring sites with a smaller gas meter can readily use this technology. The larger Infinity Solo model will also act as a high-efficiency alternative to gas fired storage appliances that exist in today’s market. The cylinder is stainless steel and this reduces the weight compared to glass lined models, and it makes transportation, handling and installation a lot easier. As well as the difference in weight, the cylinders also have extremely low heat loss figures (as low as 1.41kW/h day), so the user pays less to

maintain the heat within the tank. Another benefit of the Infinity Solo with stainless steel cylinder is that the life expectancy of the material is far greater than that of a glass-lined equivalent as glass suffers from thermal shock causing it to crack after a period of time. The Infinity Solo range is also renewables compatible and supplied pre-fitted with a coil, meaning that the primary energy source will always be from renewable gains and the complementary Rinnai water heater will only apply the precise amount of gas to boost the difference in temperature. Rinnai manufactures the energy efficient Infinity range of low NOx gas fired continuous flow water heaters and space heaters. The Infinity brand carries

the widest range of condensing water heaters on the market today with the most impressive efficiencies in operation, leading the field in technological innovation. www.rinnaiuk.com

The first in a series of regional Public Sector Energy Events will kick off in London on 30 April 2019 at Emirates Stadium. For more information, please visit: http://bit.ly/pseelondon 24

G P BURNERS LAUNCHES FACILE RANGE OF SELF-REGULATING BURNERS

S

windon based combustion equipment manufacturer, G P Burners, has launched its FACILE range of fully automatic burners. The company claims that the new, state-of the-art models are the first self-regulating burners for industrial and commercial combustion applications. The patented FACILE burners feature innovative and smart technology to deliver ease of operation, faster commissioning, optimum performance, energy efficiency and reduced emissions. FACILE burners independently and automatically set up plant parameters such as temperature, pressure and boiler power, as well as reacting to ambient variables including altitude and climate. The system recognises and adapts to all types of boilers and processes for optimum performance. These characteristics simplify installation and dramatically reduce commissioning time, compared with conventional burners. For the rare occasions when operator intervention is required, FACILE units have a user-friendly LCD controller.

During operation, FACILE burners have a proactive and self-regulating mass flow sensing capability, automatically adjusting fuel and air flow. The ignition point is burner determined and regulated to ensure optimum ignition. These features help to ensure inherently safe operation, optimum combustion and reduced energy consumption. FACILE’s intelligent technology facilitates remote operation and data monitoring via PC, laptop, tablet and IPhone. Plant performance is constantly monitored and real time alerts are issued promptly, highlighting performance or maintenance issues. Depending upon the nature of the data, notifications are relayed to the relevant party, which may be the manufacturer, the installer or the plant manager. Operational statistics are measured against key performance indicators, providing an up-to-theminute overview of plant functions and efficiency. These smart features also provide the resources for preventative maintenance regimes and remote

system diagnostics, simplifying and reducing service management costs. The FACILE range includes six LO NOx models with emissions of less than 80 mg/kWh (Class 3) and a power output range from 100 to 810 kW. Seven standard models are also offered with emissions of less than 120 mg/kWh (Class 2) and a power output range from 450 to 4100 kW. NOx emissions may be further reduced by incorporating an optional flue gas recirculation system. The company plans to add additional models, with higher power capacities, during 2019. www.gpburners.co.uk

LIGHTING

LED LIGHTING IS TAKING THE LEAD IN THE HOTEL INDUSTRY Over the last two decades, the hotel industry has seen an increased awareness of sustainability issues amongst both customers and management, including the environmental, economic and social impact. Hoteliers are promoting “green” initiatives to make their hotels more sustainable, thus enhancing their reputation and increasing levels of customer satisfaction. As energy costs continue to rise, many hotels have adopted ecofriendly policies, implementing energy efficient technologies and practices to save money and gain a reputation as a “green” hotel. 26

L

ighting accounts for a significant percentage of energy use and the most obvious benefit of upgrading to LED lighting is the improvement in energy efficiency. This has an immediate impact on the monthly electricity spend (from lighting), with a corresponding reduction in carbon footprint. As well as demonstrated energy savings of 85% or more, maintenance savings of up to 100% can be made. Typical return on investment calculations show full payback from as little as 3 months. Few need convincing of the financial advantages of LED lighting, but there is still a perception they may be efficient and long lasting, but do little to enhance the ambience of the premises. Great for offices, warehouses, production floors, but atmosphere-killers in the hospitality industry. Nothing could be further from the truth. The colour temperature of LED lighting is highly controllable, and manufacturers are introducing character lighting ranges specifically designed for environments where the warm glow of an incandescent bulb is a valued feature.

REAP THE REWARDS – AND SAVE AS YOU GO As well as an immediate improvement in energy and other costs, existing ballasts and control gear (which can utilise a further 20% energy) are eliminated. Moreover, LED lamps from reputable manufacturers come with lengthy guarantees and there are further cost savings from a reduced burden on maintenance.

ENERGY MANAGER MAGAZINE • JANUARY 2019

All this makes a very strong case for moving to LED technology. Fortunately, this can be achieved without throwing away the existing infrastructure – and past investment. LED lamps and luminaires are readily retrofitted within the current lighting scheme. In addition, retrofitting is the least business-disruptive way to upgrade existing lighting. Installation is quick and work can be scheduled around downtimes, so that operation can continue as normal. For offices, warehouses and industrial buildings, LEDs provide qualitatively better lighting, on top of an overwhelming quantitative benefit. For example, LED technology provides a directional form of light, so it can be focused where it is needed. LEDs are flicker-free, combatting the common problem with fluorescent lighting. High performance LED lighting is highly consistent, contributing to a good even spread of light,

without any colour shifting or contrast imbalances. Good quality LED lighting is well suited to building automation and control, since there are no issues with being turned on and off.

and provide a high-performance lifespan of 30,000 hours - around ten times that of a conventional filament bulb. Savings are up to 90% on energy savings and running costs.

LED FILAMENT BULBS – SAVINGS WITH STYLE

HAPPY OUTCOMES

The Bright Goods range of retrofit LED filament light bulbs have been designed to replace incandescent and filament-based lighting technologies which give all of these benefits in lights that create a warm and welcoming ambience. Such traditional filament light bulbs are going through something of a resurgence in popularity. From industrial style enamel pendants, to just being hung bare, with coloured flex, the appeal lies in the classic shapes, the glass, the brass and the filament. However, traditional ‘filament’ bulbs remain unreliable, short-lived and power-hungry. The solution is a range of antiquestyle filament LED lamps, carefully handcrafted to look exactly like traditional bulbs in an array of classic, well-loved vintage shapes. These innovative LED filament lamps simply plug into existing fittings to highlight and improve almost every kind of interior space. Where a traditional filament bulb consistently in use over 10 hours a day would require replacing in less than a year, these lamps are fully dimmable

Satisfied customers include DoubleTree by Hilton and the first Premier Inn in Germany, who replaced their old lighting with long life, energy efficient LED filament lamps. A more individual example of a Bright Goods installation is at the world’s tallest Novotel in London’s Canary Wharf. The LED filament lighting was specified as part of the AccorHotel Group’s PLANET21 sustainability programme to increase its energy efficiency and environmental performance. Louisa Daxer-Robbins, Operations Manager at Novotel, commented “The LED filament lamps are aesthetically beautiful and have helped to achieve the coveted ambience we were looking for, complementing the bespoke design of each individual area within the hotel. Furthermore, they offer an impressive energy saving of up to 75% which fulfils our criteria for sustainability.”

CONCLUSION Whilst the financial gains and environmental reasons for making the switch to energy efficient LED lighting

are clear, good lighting can visibly transform the hospitality experience and leave a lasting, positive impression for the visiting guest which is key to ensuring customer loyalty. This in turn will enhance a hotel’s reputation and boost brand awareness. Hotel owners now look to create an environment that will make their hotel stand out in terms of elegance and sustainability. http://www.ledecolights.com/

RENEWABLE ENERGY

DOUBLE-SIDED SOLAR PANELS COULD BRING £400M OF ADDITIONAL ANNUAL REVENUE TO THE SCOTTISH ECONOMY, SAYS HERIOT-WATT UNIVERSITY A scientist from Heriot-Watt University, in partnership with industry partners Wood, is building a model that aims to highlight the benefits of the country moving to double-sided solar panels (bifacial solar cells) rather than using the current singlesided panels (monofacial).

B

ifacial cells can produce up to 25% more energy with the same projected area due to their ability to convert irradiation captured on both the front and rear sides. However, their current market share remains very low at around 5%. According to the Solar Trade Association the installed capacity of Scottish solar panels will rise to 1.5GW by 2030. The 25% enhanced energy yield of bifacial versus monofacial panels with the same projected area, could mean generation would increase to almost 2GW. This would equate to: • £400m of additional annual revenue to the Scottish economy • Over 2000 new jobs • £200m a year energy savings for Scottish industry and households • Over half a billion kgCO2/ year emissions reduction Dr Mehreen Gul, Assistant Professor at Heriot-Watt University explains: “Although the development of bifacial solar cells dates back to the 1970s, due to the expensive cell structure, bifacial modules have remained a niche product in the market. “In contrast to single sided cells, bifacial cells collect radiation on the front and rear side as they capture light reflected from the surface beneath the module and from the surroundings. On

flat roofs, ground-mounted installations or locations that might not initially seem the best for a solar panel, bifaciality can improve energy generation by up to 25% more than standard panels. “The advent of new and economically viable glass provides the ideal technology for generating higher energy yields. However, before this technology sees large-scale market distribution, several hurdles have to be overcome. Unlike single-sided panels, we need to examine the ‘albedo’ (light reflectivity) of the surface underneath the panel that can affect performance and then make accurate energy yield assessments by adapting and using state-of-the-art modelling tools. We will also perform a detailed investigation into high albedo surfaces in relation to radiation augmentation of bifacial modules, ageing, degradation, costs and environmental impact.” Alan Mortimer, director of innovation at Wood, said: “Heriot-Watt University is recognised as the best in its field and we are thrilled to, once again, be working together to create a lowcarbon future. Bifacial panels with their lower cost of energy will help accelerate the global energy transition by allowing many more companies and consumers to make the switch. “Solar energy is one of the fastestgrowing renewable technologies and through this partnership, we will not only

drive continuous improvements for our customers but also boost the quality of research within the university by ensuring it has practical applications in industry.” Scotland’s Energy Efficiency Programme (SEEP) aims to make Scotland’s buildings as close to zero carbon as possible by 2050. Combining storage with wind and solar assets such as bifacial solar cells with enhanced generation potential, presents a valuable solution for the energy system as a whole, offering opportunities for locally managed demand. This kind of flexibility and control will be important with the uptake of heat-pump assisted electric heating and as electric vehicles become an integral part of the transport system. The clean and increased onsite generation using bifacial panels, coupled with the development and use of innovative software, could also reduce the need for investment in more expensive and disruptive ‘hardware’ in the form of grid upgrades. It is hoped the research will be used internationally to build a case for bifacial panels across the globe. An Energy Technology Partnership Award with contributions from Wood and Heriot-Watt University is funding the research. Input is also being provided by Edinburgh Napier University.

RENEWABLE ENERGY

100% RENEWABLE ENERGY ACROSS EUROPE IS MORE COST EFFECTIVE THAN THE CURRENT ENERGY SYSTEM AND LEADS TO ZERO EMISSIONS BEFORE 2050 New scientific study models full energy transition across power, heat, and transport sectors

A

s climate discussions are underway among global leaders at COP24, the annual United Nations Framework Convention on Climate Change (UNFCCC) conference, a new report released Tuesday showcases the feasibility of a European energy transition to 100% renewable sources. The new scientific study shows that the transition to 100% renewable energy will be economically competitive with today’s conventional fossil fuel and nuclear energy system, and lead greenhouse gas emissions to zero before 2050. The study’s financial case for an energy transition becomes even stronger when taking into account significant projected job growth and the indirect economic benefits for health, security, and the environment, that were not factored into the study. Undertaken by LUT University and Energy Watch Group, the first-of-its-kind scientific modelling study has simulated a full energy transition in Europe across the power, heat, transport, and desalination sectors by 2050. The study’s publication came after approximately four and a half years of data collection, and technical and financial modelling under the research and analysis of 14 scientists. “This report confirms that a transition to 100% renewable energy across all sectors is possible and not more expensive than today’s energy system,” said Hans-Josef Fell, former German parliamentarian and president of Energy Watch Group, during its COP24

30

press conference, “It demonstrates that Europe can switch to a zeroemission energy system. Therefore, European leaders can and should do much more for climate protection than what is currently on the table.”

Europe’s annual greenhouse gas emissions decline steadily through the transition, from approximately 4200 MtCO2 eq. in 2015 to zero by 2050 across all sectors.

Some of the study’s key findings:

A 100% renewable power system will employ 3 to 3.5 million people. The approximate 800,000 jobs in the European coal industry of 2015 will be zeroed out by 2050, and will be overcompensated by more than 1.5-million new jobs in the renewable energy sector.

The transition will require mass electrification across all energy sectors. Total power generation will exceed four to five times that of 2015, with electricity constituting for more than 85% of primary energy demand in 2050. Simultaneously, fossil fuels and nuclear are phased out completely across all sectors.

Electricity generation in the 100% renewable energy system will consist of the following mix of power sources: solar PV (62%), wind (32%), hydropower (4%), bioenergy (2%) and geothermal energy (<1%).

Wind and solar make up 94% of total electricity supply by 2050, and approximately 85% of the renewable energy supply will come from decentralized local and regional generation.

100% renewable energy is not more expensive: The levelised cost of energy for a fully sustainable energy system in Europe remains stable, ranging from 50-60 €/ MWh through the transition.

ENERGY MANAGER MAGAZINE • JANUARY 2019

“The results of the study showcase that the current goals set forth under the Paris Agreement can and should be accelerated,” said Dr. Christian Breyer, professor for solar economy at Finland’s LUT University, “The transition to 100% clean, renewable energy is very realistic, right now, with the technology we have available today.” The study concludes with policy recommendations to promote a swift uptake of renewable energy and zeroemission technology adoption. Primary measures promoted in the report include support of sector coupling, private investments, tax benefits, legal privileges, with a simultaneous phase out of coal and fossil fuel subsides. By implementing strong political frameworks, the report shows that a transition to 100% renewable energy can be realised even earlier than 2050. www.lut.fi/web/en/.


DRIVING THE FUTURE

AT LEAST EIGHTY-EIGHT NEW, FREE RAPID-CHARGE POINTS TO BEINSTALLED FOR ELECTRIC VEHICLES ACROSS WEST YORKSHIRE

W

ork to improve West Yorkshire’s air quality by encouraging the use of electric vehicles, through the installation of at least 88 new, free rapid charging points is set to get underway in 2019. After securing almost £2 million from the Government’s Office for Low Emission Vehicles (OLEV) for the work, West Yorkshire Combined Authority has appointed energy and services company ENGIE to install and operate the new charging points. Each charging point will have two charging bays. One will be specifically for taxis and private hire vehicles and the other will be for all other users. Typically, the charging points will provide a full charge to an electric vehicle in around 20 to 30 minutes and will be free to use until late October 2021. The Combined Authority and its district partners, Bradford, Calderdale, Kirklees, Leeds and Wakefield councils are providing £1.2m of match funding. ENGIE will install, own and operate the charge points for at least 10 years. Work will soon get underway to identify suitable and convenient charge point locations. Cllr Kim Groves, Chair of the West Yorkshire Combined Authority Transport Committee said: “Improving air quality across West Yorkshire and Leeds City Region while at the same time developing the transport networks vital to supporting inclusive growth is one of the Combined Authority’s key aims and this work will help us achieve that. “Installing new charging points at these 88 sites, where people can charge their vehicles for free, is designed to encourage the transfer to electric vehicles. “Making half the bays exclusively for the use of taxis and private hire vehicles could result in up to 500 diesel taxis and private hire vehicles being converted to hybrid and pure electric versions by 2020, which would reduce Nitrogen Dioxide emissions from taxis by as much as 18%, in line with our target of developing Clean Energy and Environmental Resilience for Leeds City Region.” Cllr James Lewis, Leeds City Council’s executive member with responsibility for sustainability and the environment,

said: “Most residents agree that tackling air pollution in order to protect the health of everyone in Leeds should be a priority. As vehicles are the biggest contributor to outdoor air pollution in the city, everyone that switches to a zero-emission vehicles will be making a real difference to the air we breathe. “In our recent consultation, many residents and businesses in Leeds told us that they’d be more likely to switch to a cleaner electric vehicle if there were more places to charge. By installing 30 charge points in and around Leeds within the next year, this scheme will make it easier and more accessible for residents to do their bit.” Wilfrid Petrie, CEO of ENGIE UK and Ireland said: “ENGIE is committed to improving the lives of people in cities and urban areas by tackling air pollution and we believe the provision of rapid electric vehicle charge points across the West Yorkshire region will help encourage more people to choose a low emission vehicle. “The provision of green mobility solutions is part of ENGIE’s wider strategy to combine our capabilities to assist local authorities and other public sector customers with placemaking – working alongside them to shape the future use of their estates and public spaces. “We have seen real success and tangible improvements in carbon reduction in cities where we have managed green mobility solutions and we are looking forward to seeing this being replicated across West Yorkshire.” Several major private hire and taxi firms across West Yorkshire provided letters of support for the Combined Authority’s successful funding bid. Taxi and private hire drivers would be able to reserve time slots at the new charge points in what will be the second biggest project to provide charge points for taxis outside of London. Cllr Alex Ross-Shaw, Bradford Council’s Executive Member for Regeneration, Planning and Transport, said: “As part of our Low Emissions Strategy, we want to encourage residents and businesses in Bradford to consider switching to electric vehicles, and one of the best ways to do this is to make it convenient and free for people to access charging points.

“We are determined to increase our commitment to reduce the Council’s carbon footprint while staying at the forefront of new ultra-low emission technology. Encouraging the use of electric cars helps us achieve both and we hope that the additional 20 charging points will make Bradford drivers think about making their next car an electric one.” Calderdale Council’s Cabinet Member for Planning, Housing and Environment, Cllr Daniel Sutherland, said: “We’re pleased to be a part of this forward-thinking scheme which will benefit drivers across the region. It will be of particular benefit for those who make regular journeys, like taxi drivers, and having the charge points in taxi bays will be a real incentive for drivers to switch to an ultra-low emission vehicle. “We’re committed to improving air quality in the region and by increasing the number of electric vehicles, more communities will benefit from cleaner air as part of a greener and more sustainable transport network.” Cllr Shabir Pandor, Leader of Kirklees Council said: “The continued mass use of petrol and diesel fueled vehicles is not sustainable. They’re damaging to our environment and our health. That’s why we are committed to reducing our carbon footprint, across Kirklees. As well as developing a broad transport infrastructure, including contributing to a regional strategy, we want to encourage the use of sustainable transport such as electric vehicles. “The investment in 17 free rapid charging points, several of which will be for taxis, is a step in the right direction in helping reduce our impact on the environment.” Cllr Maureen Cummings, Cabinet Member for Environment and Communities at Wakefield Council, said: “Having these charging points in place in our district and elsewhere in West Yorkshire will mean these vehicles are a practical alternative to petrol and diesel cars and I hope will encourage more people to consider it as an option.” ENGIE has provided over 60,000 charge points worldwide and designs, installs, operates and maintains its charge points for public use, businesses and for home installation. The company already has a strong presence in Yorkshire where it provides a wide range of energy, services and regeneration activities - including energy efficiency improvements to over 3,000 homes as the delivery partner of the Better Homes Yorkshire initiative. In 2017 ENGIE’s public charge points in Rotterdam delivered 480,000 transactions and supplied 3.6 GWh of renewable energy – this equates to 30 million driving kilometres and a reduction of 4.5 million kilograms of CO2 in just one year. www.engie.com

DRIVING THE FUTURE

CONSUMERS READY TO FULLY EMBRACE THE TRANSITION TO ELECTRIC BUSES Håkan Agnevall, President Volvo Buses

I

n 2017, approximately 50,000 deaths in the UK were attributed to toxic air and man-made chemicals1. This unacceptable death toll once again places the discussion regarding urban mobility firmly front and centre as the transport industry continues its drive towards delivering cleaner, quieter and more efficient vehicles. Meeting emission targets has become an on-going challenge as the desire to transition towards fossil fuel alternatives gathers pace. This at a time when mass urban transport needs continue to grow exponentially across our cities. I believe that a key component of energy efficient and sustainable public transport systems comes in the form of electromobility and in particularly, electric buses. Not only does this help to reduce the overall number of vehicles on our roads but it also helps to meet ever stringent targets rightly set by legislators. The move towards a better public transport system is a journey in itself. That said, the need is now beyond question and whilst improved efficiencies in diesel should not be ignored, e.g. biodiesel such as HVO, e-mobility is quite simply the next step in public transport. An environmentally friendly, energy efficient and attractive system that enables more of us to travel together is no longer ‘a nice to have’, but an absolute ‘must have’. 2018 has seen an increase in electric bus trials and investments by city authorities as they attempt to meet these ambitious targets. This is helping to make the transition to electric buses mainstream, with a recent report predicting that half the world’s buses will be electric by 20252. A new survey of road users commissioned by Volvo Buses looked at the future of urban transportation. It shows that nearly 60% of Britons 1 Report by Icahn School of Medicine in New York City, Oct 2017 2 Bloomberg New Energy Finance, Feb 2018

are now willing to embrace a fully electric bus network, whilst 82% not surprisingly stated that air quality was important to them. However, achieving this by creating cities with a greener transport infrastructure can sometimes mean embracing change that not everyone is ready to adopt or support in the short term.

ENERGY MANAGER MAGAZINE • JANUARY 2019

Some perceive there to be difficulties implementing the infrastructure needed, the cost of delivery or even a change in transport habits. However, the survey suggests that the tipping point amongst the public has arrived, with some of the perceived challenges outweighed by the longer-term benefits they will bring. When considering greener transport


DRIVING THE FUTURE

choices now and in the future, the survey shows that the British love affair with the car continues, with 47% declaring it as their preferred mode of transportation. This was followed by bus travel, with 20%. When it comes to generational differences, 60% of Britons aged 55 and above use the car most often, whilst 18% use the bus, compared to 28% and 27% respectively of 16 to 24 year olds. When asked about their likely choice of transport in 15 years’ time, 61% of respondents aged 16 to 24 see themselves using their own car most often, compared with 40% of those aged 55 and over. Although millennials may now have access to a greater choice of transport services, the car looks set to dominate for some time to come. This in my view is not a sustainable proposition if we are serious about tackling air quality, congestion and noise pollution moving forward. The more people we have travelling individually in vehicles the more congested our streets will become, even if these vehicles are electric. This will continue to slow down journey times. London for example, removed 30 per

cent of the road capacity for private vehicles in central London between 1996 and 20103. Therefore, increased congestion is set to worsen before it improves, if the love affair with our cars continues as predicted by our findings. When it comes to the recent proliferation of on-demand services such as Uber, 44% would still rather choose a bus even though only 9% would chose it for speed reasons. This highlights the need for authorities to support the prioritisation of mass public transport. Indeed, more than half of those surveyed (55%) also felt more needs to be done with city planning to prioritise bus networks within an integrated transport system. I feel we all need to move towards options that can carry increased numbers of people around our busy streets. Adding more vehicles simply isn’t the answer. 3 Channel News Asia, 11th September 2018

According to respondents, the top five reasons apart from fares which would make them take buses more often are: • More frequent services (28%) • Routes to places they need to go (25%) • Bus stops nearer to home (22%) • Buses that can get them to their destination quicker (14%) • Cleaner bus on the inside (12%) The exciting reality is a cleaner and quieter electric bus network also allows for the placement of bus stops in unexpected places such as libraries, hospitals or shopping centres. With no emissions and reduced noise pollution, there are few restrictions on where these stops could be in the future. There are misconceptions about the public bus system that we as an industry and society need to overcome, because what is clear is that the future of mass public transport is electric, with some elements of biofuel. However, this is something that we as an industry can’t do alone. By working closely with city officials, city planners, utilities and the transport users, fully integrated electromobility, including electric bus systems will arrive far sooner than many had expected. A truly sustainable and energy efficient public transport future is in our grasp and I believe the expectations and desire of the public to make this the only future, is now closer than ever. www.volvobuses.com/
