THE COST OF ENERGY STORAGE is something we track closely at the Energy Storage Council. The cost of an automotive vehicle battery pack, ex-factory, is currently sitting at around US$250. This is a big drop from around US$600 only three years ago. Of course customers are looking for the most cost-effective way to store energy. That’s why conducting an energy efficiency audit at the outset is so important.

A kilowatt hour of electricity you don’t use is the cheapest kilowatthour (you won’t buy). On top of that, other forms of energy storage, such as dumping excess solar PV energy into super insulated hot water tanks, is such a good idea. Recent modeling showed that an effective kilowatt hour of energy storage in the form of hot water cost around $72 to set up (excluding the cost of solar PV). Third, companies are increasingly deploying smart energy management software with their energy management systems. These smart computers learn on the job. They map, optimise, and predict the energy required in a home or business, against forecast solar radiation. By tailoring a smart energy solution, the capacity of batteries required is reduced. Thoughtful planning and a good design, based on energy efficiency, diverse energy storage options, and smart software, will open the energy storage market further still. In parallel, lithium ion battery and balance of system costs will continue to fall in price. So the smaller capacity of batteries required will also get cheaper. These two trends will merge to deliver better, more economic tailored solutions for every energy customer.

Local and Global NEWS ARENA HAS HELPED GENERATE 490 MW OF BIG SOLAR by securing $87 million funding within just two years of its competitive funding program. Australia’s large-scale solar industry has grown from zero to more than 20 plants in just five years, and the 12 largescale solar plants supported by ARENA will become a reality and triple Australia’s large-scale solar capacity. ARENA’s new Investment Plan outlining the investment priorities in the transition to reliable, affordable and low emission energy that will guide almost $800 million of funding over the coming years, Innovating Energy sets out to: deliver a secure and reliable electricity system, accelerate solar PV innovation, improve energy productivity, and export renewable energy. And as part of its broader effort to accelerate the shift to an affordable and reliable renewable energy future ARENA is now reaching out to the mining community. But wait, there’s more: ARENA is trialing blockchain technology that enables households and business to trade or share power with one-another. AGL is leading the project to evaluate a virtual trial at homes with a mix of solar panels, batteries to store electricity, and ‘smart’ air conditioning. IBM Australia is also involved and will focus on the applicability of blockchain technology to recognising, authenticating and settling energy trading while an energy consultant provides market analysis. The trial will help understand if there is value in peer-to-peer markets and how blockchain technology could facilitate this market in a cost effective way. It will also provide valuable information for regulators, energy service companies, start-ups, retailers, and networks on how peer-to-peer trading affects markets and market participants, and how this market could be further developed.

CEFC’S NEW CHIEF EXECUTIVE IAN LEARMONTH (pictured above) describes this point in time as exciting for Australia’s broader energy sector. In less than four years the CEFC has made investment commitments of more than $3.5 billion, and has a strong pipeline of potential investment opportunities. “The CEFC has an important role to play in Australia’s clean energy transition and the development of a resilient, balanced and secure electricity system … to help deliver our transformation to a low carbon economy,” he said. The CEFC recently announced finance for its tenth project through its Large-Scale Solar Program, bringing its total program investment commitments to more than $370 million, accelerating projects with a total estimated project value of $900 million and a total generating capacity of more than 400 MW (AC).

“It is difficult to overstate just how profound the impacts of wide-scale, low-cost energy storage will be on the utility sector.”

THE ENA’S ELECTRICITY ROADMAP finds that by 2030, around 40 per cent of both Victoria’s and Western Australia’s energy could be generated by intermittent renewables (as is the case in South Australia today). New South Wales and Queensland are expected to follow suit in the 2030s as more coalfired power generators shut down. “The Roadmap forecasts up to 10 million households and small customers will have distributed energy resources like solar, storage, smart homes and electric vehicles by 2050,” ENA’s John Bradley said. With a co-ordinated plan, by 2050 $16 billion in network infrastructure investment is avoided by management of distributed energy resources like solar and batteries and network charges would be 30 per cent lower than 2016. “The intense level of project development will only be possible with a national transition plan like the Roadmap and stable and enduring carbon policy to support investment.” www.energynetworks.com.au/roadmap See more on page 16. 6 WINTER 2017

INDUSTRY COMMENTARY

Energy market shake-up: if not now, when? ACCORDING TO Australian Solar Council Patron and Global greens ambassador Christine Milne solar energy with storage linked with data analysis, virtual power stations and demand management is the “game changer the planet needs”. It’s the dynamic that is transforming the future of energy while reducing costs for business and households. And the increasing affordability of large-scale solar which now sits at around $70 MWh makes solar energy the most competitive among all electricity generators. So much so the Australian Energy Market Operator is now fielding high volumes of inquires inquiries for new wind and solar projects: up to 1000 in contrast with the 20 normally received in a month. Anthony Arrow, a partner at Pinsent Masons which provides infrastructure and energy legal advice says as procurement and funding costs are coming down, utility scale PV solar is fast becoming the preferred investment option for renewable energy developers in Australia. “We will also see an increased number of joint ventures, mergers or acquisitions between solar and battery storage solution developers as key players jostle to strengthen their market positions,” he told Solar & Storage. “There’s way more money than solar deals available … local and international investors have found themselves having to kiss a lot of frogs, with billions of dollars chasing hard after solar opportunities.” He added that increasing numbers of opportunistic property developers are buying up land in NSW and Queensland in the hope of turning them into solar farms.

Turning a blind eye The level of interest in renewables on a micro and macro level may be greater than ever but is the National Energy Market geared up for the transition? The consensus appears to be a resounding ‘no’. The NEM remains locked in a time warp where fossil fuels dominate the landscape and prices in the wholesale electricity market continue to soar. This makes a mockery of the coalition government policies which three years ago resulted in the binning of the carbon tax, claiming the move would lower household energy costs. Not so: wholesale power prices have since

doubled. And whatever happened to carbon emission controls to curb global warming? The acceptance of climate science indicates the acceptance of the economic tools needed to internalise the costs of damage from carbon and other greenhouse gas emissions, says Solar Council President Steve Blume. The latest report from the High-Level Commission on Carbon Prices, a group of 13 of the world’s leading economists is blunt: we must see a strong carbon price in the range of US$40 to US$80 per tonne of CO2 by 2020, and $50 to $100 per tonne by 2030. Report authors wrote ‘A welldesigned carbon price is an indispensable part of a strategy for reducing emissions in an efficient way.’ Blume remarked “In Australia we have no national emissions standards and no plan for an orderly decommissioning and replacement of our rapidly aging fossil fuel generation fleet, let alone a carbon price mechanism. We need them all urgently as well as major energy market reform.”

NEM shortcomings Christine Milne agrees. “Changes to NEM rules need to be more than a focus on energy security and price. They must link energy security and price to addressing global warming,” she stated. “Energy is not just about jobs, new technology, air quality and cheaper power bills, but also is the key determinant of whether humanity survives in an age of rapidly accelerating global warming. “The National Electricity Objective must be amended to include climate change and environmental factors. This would make the NEM a primary instrument to facilitate and be consistent with Australia’s global warming targets under the Paris Agreement. This is essential to drive the fastest possible transition to 100 per cent renewable energy and the jobs, health and community benefits that follow.” The shortcomings of the NEM received widespread attention at May’s Solar and Storage conference staged by the Solar Council whose chief executive John Grimes is among many urging market reform.

“Changes to NEM rules need to be more than a focus on energy security and price. They must link energy security and price to addressing global warming.”

An outdated system that urgently needs to be modernised

“The National Energy Market is no longer fit for purpose,” he said. “We have a disjointed energy policy and management structure. We cannot meet international emissions commitments. Unless the NEM is changed it will not offer the lowest cost and cleanest and most reliable electricity supply for consumers.” Victorian Renewables Advocate Simon Corbell – the architect of ACT’s flourishing clean energy program – is calling for an emissions intensity scheme, saying “It is what’s needed in the energy sector and must be addressed. And other fundamental changes are necessary, networks should be smarter, more flexible and diverse and importantly fit for purpose with rapid response generations.” Corbell reckons it’s time for ministers on the COAG Energy Committee to “seize the moment and tell the AEMC they need to ensure rules are made. It’s timely – tell them the energy market is cumbersome, slow, non responsive … this must be strongly enunciated.” Shadow Energy Minister Mark Butler agrees, noting the states are losing confidence in the NEM, South Australia in particular has not been served well by the market, and that there are many issues around the cost and supply of gas. “We need a broad energy vision along the east coast,” Butler says.

Time for change Newly appointed AEMO chief Audrey Zibelman has already determined the time is right to change business models, stating “You cannot continue using a one hundred year old model, and that is true for AEMO too, which needs to accommodate innovation. “Things are changing, and that includes customer needs and demographics and clear preferences for clean energy; [we need to switch] system orientation from domination of central power plants to managing data with solar and storage and electric vehicles; and rapid technological advancements, the pace of change in the past has been very slow. “In a market that captures the transition gentailers also need to consider their role and the market design must change and regulatory incentives need to be reviewed to address consumer value and returns,” she said. Zibelman’s colleague Ben Skinner of AEMO agrees that the networks are no longer dealing with passive customers, saying “The way of the future of power systems, changes are driven by new technology, inventions, also customer choice and government policy. AEMO will play a role and supports a competitive market.” Skinner revealed that AEMO’s submission to the Finkel Review of the Energy Market included the creation of performance procedures and standards and greater visibility for distributed energy resources.

The Finkel Review – delight or disappoint? Many are pinning hopes on the Finkel Review* scripting a sensible blueprint for energy market reform. Steve Blume summed up the thoughts of many when he remarked “Our hope is that the Finkel report is a catalyst for sensible reform and that it provides the opportunity for changes that factor in today’s consumer market as well as environmental imperatives – by which I mean carbon abatement.” Will the renewables industry feel elated or compromised by the contents of what is arguably the most timely and vital report into the electricity industry? Chief Scientist Alan Finkel has in the past expressed strong opinions on the need for carbon reduction and the importance of energy storage. His Committee’s first Report was bold, but will that boldness prevail in the final report? And will the Government response be on the evidence base the Finkel Report will provide or on ideology?

In what way does the NEM need to evolve? What actions are needed, by whom? More questions than answers. John Hewson who is now driving developments in CST joins the masses hoping the Finkel Review will provide answers and direction on the road to integrating renewable resources. However he suggests the Chief Scientist would have been “better off starting with a blank piece of paper rather than being charged with the task of patching the existing electricity system”. Still more doubts and questions: Instead of presenting a template for the twenty first century energy market will the recommendations of Finkel Report be ignored or perverted due to political pressure? Will our political leaders muscle in and obstruct the optimum outcome? Does the termination of the Climate Change Authority and the attempt to destroy the RET and abolish ARENA and the CEFC suggest an ominous response from this Government? One thing we do know is that AEMO’s wish list to the Finkel submission included the creation of performance procedures and standards and greater visibility for distributed energy resources. Audrey Zibelman commented “Australia is leading the world in what energy will look like. Australia can become a centre of excellence. AEMO needs to get it and be the best in the world.” We agree, but we need massive market reform, and we need it now. *By the time this magazine is in circulation the much-anticipated Finkel Review will have been presented to the Government.

Solar Council’s six-point plan for NEM reform The Australian Solar Council and Energy Storage Council call on all Energy Ministers to implement the following key measures: • Establish a plan for the orderly closure of coal-fired power stations • Make action on climate change a key objective of the National Electricity Market • Commit to at least 50 per cent renewables by 2030 • Introduce a 5-minute settlement rule • Enable markets in peer to peer trading and demand response; and • Replace the Australian Energy Regulator and Australian Energy Market Commission with a new combined energy rule maker and regulator.

One small but significant step forward In mid May the renewables industry welcomed the new AEMO and ARENA trial in which customers will be paid for reducing their energy use during times of peak demand to help avoid blackouts. The $22.5 million initiative will be trialled over three years in Victoria and South Australia and realise the potential to engage customers to save costs, keep the lights on and reduce carbon emissions. Energy Networks Australia CEO John Bradley commented on the smart energy security and emission reduction solutions saying “An integrated grid using demand response can enable increased use of variable solar and wind generation on our electricity system.” He added that rewarding customers for their energy choices is an integral part of the Electricity Network Transformation Roadmap recently released by Energy Networks Australia and CSIRO. “For instance, networks could buy grid support from millions of customers in demand response programs or using household solar and storage to save $16 billion in network costs by 2050.” (More details page 16.)

INDUSTRY COMMENTARY

The BEAST and the blame game Fiona O’Hehir of Greenbank Environmental is a vocal campaigner for clean energy. Here she presents some cold hard facts about the South Australian blackout that could have been avoided.

AUSTRALIA OPERATES probably the longest interconnected power system in the world. The whole of the eastern seaboard from Queensland to South Australia is connected together through a series of “interconnectors” across our state borders. This beast (the National Electricity Market) is vast and comprises thousands and thousands of substations, thousands of kilometres of powerlines and we have lost count of the number of power poles installed throughout the network. There are over 19 million end users and more than $11 billion of electricity is traded through the NEM annually.

“The outages which occurred

Any piece of infrastructure is open to faults and things going wrong due to equipment failure, damaged cables and defective electrical equipment. Unfortunately after the South Australian outage of 2016, what is now occurring in the political and regulatory arenas is the “he said, she said” blame game and the issue of intermittency of electricity supply. I would say that the “grid” itself is suffering from an intermittency problem through lack of planning and a severe lack of redundancy in the NEM in general. N+1 is not a new engineering concept when we are talking about a mission critical supply. Although we can have an in depth technical argument about whether it was the input from renewable energy that caused the instability or not, the problem is much deeper than that. Years of the inability of either federal political party to tackle the hard tasks of reform through COAG, even more state politicians seeking political gain through exaggerated and unsustainable feed-in tariffs has now led to complete and utter policy paralysis at all levels.

and distribution operators, the energy suppliers of all persuasions, politicians and senate inquires, with still no sensible long term plan in sight. The outages which occurred in South Australia were the direct result of the years of squandered opportunities for change and modernisation of the market and has led to a domino effect throughout the network. Two tornadoes hit the South Australia transmission network, causing damage and setting the scene for the ripple effect that eventually led to the South Australian power system being disconnected from the rest of the eastern seaboard grid. AEMO has said in its report its “analysis shows that the following system separation, frequency collapse and the consequent black system was inevitable”. The real problem is the failure of the parties to act sensibly and more importantly, in a timely manner. Sensible debate has been hijacked by vested interests. Some of the current decaying infrastructure needs to be retired as has happened in South Australia and is happening in Victoria and everyone in the industry knew it. These are normal corporate commercial decisions; if you cannot make a profit and you are losing money then don’t continue. Large infrastructure, just by its very nature, is always exposed to extreme weather events of this type. With these events on the increase due to the deleterious effects of climate change, how are we going to protect ourselves as a nation, not just South Australians from further episodes of this nature? So what now, given the glacial pace of policy development over the past 20 years? We need some common sense, that very rare herb, we need leadership and we need to develop a national strategy for all Australians, so we do not add to the ever increasing levels of anxiety and hype in the general community which does no one any good.

Paralysis Having been in the industry for many years I am extremely disappointed and annoyed at the wasted years, missed opportunities and wasted personal energy of the endless rounds of meetings with the regulators, the transmission

in South Australia were the direct result of the years of squandered opportunities for change and modernisation of the market.”

10 WINTER 2017

MARKET momentum

Two days, 150 speakers, three conference streams, 105 exhibitors and lots of specialist industry gatherings … plenty to take in at this year’s Solar and Storage Show. But one overriding tangible aspect was the fundamental shift unfolding in renewable energy both on a micro and macro level. Household PV installations have soared this year and massive developments are underway in large-scale solar. After years of uncertainty in the industry the outlook is now more positive. Here we take a look at just some of the powerful messages delivered during the two-day conference that united installers with manufacturers, wholesalers and policy makers. A positive outlook was set early on day one when keynote speaker Audrey Zibelman, the newly appointed chief executive of the Australian Energy Market Operator, painted a progressive and dynamic picture of

Zibelman presented the same messages on ABC TV where she emphasised the increasing importance of solar and storage technologies.)

and their “clear preferences for clean energy”. Signaling change is in the air Zibelman stated it was time business models caught up with today’s dynamics because “You cannot continue using a one hundred year old model, and that is true for AEMO too, which needs to accommodate innovation”. This in the context of the shift from energy supplies dominated by centralised power plants to accommodating decentralised energy through solar and storage systems and electric vehicles. “Australia can become a centre of excellence … AEMO needs to get it and be the best in the world,” she said. (Not long after the conference

Revival! Solar Council chief executive John Grimes who has spent years fighting the good fight for solar power believes the sector is now on the road to “massive transformation, with smart storage on an upward trajectory that will be complete in ten years”. The transition is propelled by three mega trends: solar PV becoming the cheapest form of electricity; the falling cost of energy storage; and the nexus between energy and IT with the rise of smart systems.

“The economics of distributed energy which are compelling should lead to massive growth” Kobad Bhavnagri of Bloomberg New Energy Finance

“Australia is leading the world in what energy will look like” Audrey Zibelman of AEMO

“We need a broad energy vision along the east coast” Shadow Energy Minister Mark Butler Kobad Bhavnagri of Bloomberg New Energy Finance also remarked on the low cost of solar, saying Australia’s utility-scale PV plants now providing solar energy at competitive rates. “By 2020 another 9 GW of renewable energy – much of it solar – will enter the system. New solar should compete with incumbent coal by 2032, it will be cheaper to build new large scale solar farms than burn coal. That will be the tipping point for industry.” Looking further ahead he forecasts 40 GW of [behind the meter] distributed energy by 2040.

“We’re in a transition right now and that includes extensive use of batteries for storage … The aim is to provide clean, reliable, secure and affordable energy” Victorian Energy Minister Lily D’Ambrosio

“Australia’s regulatory system … has been hopeless in disciplining the energy suppliers, allowing exorbitant levels of network expenditure” Tristan Edis the coming year and Ric Brazzale of Green Energy Trading echoed his words, blaming spiraling wholesale prices for bill shock. GET’s Tristan Edis pointed to skyrocketing gas prices over the past few years at a time when emission regulations have been rolled back. Simon Corbell, the architect of ACT’s highly successful clean energy program commented “Emission abatement is important, an emissions intensity scheme is needed in the energy sector [meantime] the state governments need to continue their strong roles in the transition to renewable energy … goal setting with clear targets is very important and the transition will not happen without it.” For his part John Hewson expressed his disappointment at the current state of debate in renewable energy and cited climate change “the most significant challenge of the century”. The Coalition’s inability to address fundamental energy reform was raised many times during the two-day conference and many are pinning their hopes on the Finkel Review of the Energy Market filling the policy gap. The Chief Scientist says there is no alternative than to reduce our dependence on fossil fuels and has expressed support for the growth of renewables, storage in particular. However this does not guarantee the outcome of the review. But the renewables market is evolving; the numbers of solar and storage installations are stronger than ever and ARENA, the CEFC and other innovators are driving significant developments in large-scale solar. The message? Power of, and to, the people.

SOLAR AND STORAGE ON THE RISE

Solar’s strength in numbers The renewables industry is moving ahead with renewed confidence and consumer interest. Numbers are encouraging: solar and storage installation levels are rising and projections for uptake remain strong. Here we round up some of the key data from the two-day solar and storage conference and from market analysts.

FIRST TO THE SMALL SCALE MARKET (up to 10 kWh) which is notching up strong figures this year, as seen in the following charts There has also been exponential growth in commercial and industrial installations with 30 MW capacity installed in the first four months of 2017.

263 MW of large-scale solar will be added. In all 6000 MW of new build from January 2016 is needed to meet the 2020 RET and early RET (L-RET) for 33,000 GWh of renewable energy by 2020 will be met by

Three mega-trends are changing everything: 1. Solar PV has become the cheapest energy source 2. Falling cost of Energy Storage • Tesla aims to produce 35 GWh year by 2020, BYD is adding 6 GWh a year to reach 34 GWh by 2020, Foxconn/LG capacity stands at 22 GWh, and several big capacity players including Nissan, Samsung

• LG Chem says a 5 kW PV system and 10 kWh battery can be purchased and installed for around $15,000. Based on daily consumption of 22 kWh the cost over ten years would come in at 22 cents kWh, less than cost of retail electricity • Storage systems costs are falling • By late 2017 battery prices will be around $650-$1500 kWh • Return on investment for storage will reduce from 9.6 to 5 years. 3. The collision of IT & Energy, the Rise of Smart Energy

ENA ROADMAP

Energy roadmap: 10 million with smart energy by 2010 The Electricity Network Transformation Roadmap is an evidence-based plan detailing what needs to be done during the next decade to provide Australians with secure and affordable energy and to decarbonise electricity by 2050.

“The path to zero emissions

HOW PROGRESSIVE IS THIS – a national energy plan that achieves zero net emissions by 2050, could save Australian energy customers $100 billion, and improves

by 2050 presents significant

energy security. And it’s not a wish list but the findings

opportunities.”

of the Electricity Network Transformation Roadmap produced by CSIRO and Energy Networks Australia. ENA chief executive John Bradley who presented the report findings at the Solar Council’s Solar and Storage show in May says up to 10 million households and small customers are likely to have solar, storage, smart homes and electric vehicles by 2050. They will be empowered through customer choice and control, and market fairness will prevail. He noted too that during the 2030s many coal generators would be retired. It’s welcome news, but Bradley has called for a national approach to carbon and energy policy to support commercial investment to keep the lights on “and bills affordable now and in the future”. Based on two years work and extensive consultation the Roadmap identifies the complex challenges facing Australia’s electricity system in the face of diversified energy supply and identifies a strategy for the future, as well as a deliverable plan to achieve it. The report finds that with a co-ordinated plan, by 2050: • Up to 10 million households and small customers are likely to have solar, storage, smart homes and electric vehicles • $16 billion in network infrastructure investment is avoided by management of distributed energy resources like solar and batteries • Reduction in cumulative total electricity network expenditure of $101 billion by 2050 • Electricity sector achieves zero net emissions by 2050

John Bradley speaking at the recent Solar Conference

• Customers retain security and reliability essential to lifestyle and employment

• Networks pay distributed energy resources customers $2.5 billion per annum for grid support services by 2050. • Network charges are 30 per cent lower than 2016 • $414 annual saving in average household electricity bills (compared with roadmap counterfactual, business as usual, pathway), and • A medium-sized family who cannot take up distributed energy resources is more than $600 better off annually through removal of cross subsidies. John Bradley says the findings highlight the critical need for State and Federal Governments to agree on a long-term energy transition plan and national policy frameworks. “The intense level of project development will only be possible with a national transition plan like the Roadmap and stable and enduring carbon policy to support investment,” he said, and that while integrating largescale variable renewable energy will be vital, customers will drive the transformation of Australia’s electricity system as world leading adopters of distributed energy resources. “Networks could buy grid support from customers instead of building their own infrastructure– in fact, annual payments to customers could be worth $1.1 billion within 10 years. “The orchestration of these new energy assets in the ‘right place at the right time’ could save customers a total of $16 billion in network costs by 2050.” The Roadmap finds it critical to move to fair and efficient network charges for residential and small scale

customers before 2021. Tariff reform would ensure a medium size family who can’t take up solar and storage is $350 per year better off in 2027. Work will start in the coming months on the Roadmap’s highest priority projects, but Bradley emphasised the need for “real action” by government as well as industry. The Roadmap includes new state-by-state analysis by CSIRO, highlighting when energy security and cost risks will emerge in key locations and need to be addressed in a national energy transition plan. By 2030, around 40 per cent of both Victoria’s and Western Australia’s energy could be generated by intermittent renewables as is the case in South Australia today. New South Wales and Queensland are expected to follow suit in the 2030s as more coalfired power generators shut down. CSIRO Chief Economist Energy, Paul Graham, said this means the eastern states could need to build as many as five intermittent

renewable generation projects each year for five years in the 2030s and 2040s but that “The big question is what will replace the existing fleet of coal-fired generation as they retire at different rates across each state jurisdiction. “To achieve deep decarbonisation while keeping the lights on, it’s likely the eastern states will depend on the equivalent of 25 new large-scale solar or wind farms being built in just a five year window with new building activity focussing on Victoria in the 2020s, New South Wales and Queensland in the 2030s and Victoria and Queensland in the 2040s.” More than 200 different industry representatives contributed at over 14 workshops and webinars held as part of the public consultation process. Information on the Roadmap has been viewed more than 30,000 times during the development process. For more information visit www.energynetworks.com.au/roadmap

Local and Global NEWS

IRENA’S CALCULATOR tells us that the renewable energy industry employs 9.8 million people worldwide, with global energy system creating more jobs in renewables than in fossil-fuel technologies. In the past four years the number of jobs in the solar and wind sectors combined has more than doubled. “Renewables are directly supporting broader socio-economic objectives [and] we expect that the number of people working in the renewables sector could reach 24 million by 2030, more than offsetting fossil-fuel job losses and becoming a major economic driver around the world,” IRENA’s statement read. Solar PV was the largest employer in 2016, with 3.1 million jobs, up 12 per cent from 2015. Renewable Energy and Jobs – Annual Review 2017.

KOREAN BATTERY GIANT LG CHEM has achieved global energy storage system sales equalling 2.6 GWh. The figure includes systems already installed and “firm orders” due for installation between now and 2020.  The figure “is expected to grow quite fast” over the next couple of years.

SSE’S 6 MW PLANT … AND GROWING. SSE Surpass Energy (Australia) Major Projects director Colin Gillam (pictured third from right) says that any day now the first of the three-phase Whyalla solar plant will be completed. That’s good news for the project that kicked off back in 2015 with only a handful of investors, council approval but no federal funding. However the project did gain the support of the South Australian government and more investors and by 2019 the full planned 150 MW project will become the state’s first utility-scale plant. SSE which has been working with BYD energy storage solutions has submitted an expression of interest to the SA Government to provide up to 100 MW of battery power storage. The plant is a landmark development in a landmark location, Whyalla boats 300 days of bright sun a year and provides the perfect home for solar. The steel city is now being recast the solar capital. Touring the plant earlier this year SA Premier Jay Weatherill said “There is an extraordinary solar resource here … there’s also potential for Whyalla to be a part of a renewable energy future and all of the jobs and technology that are associated with that … the best days are ahead of Whyalla.” www.whyallasolarfarm.com

TECHNOLOGY PIONEER ABB is providing 100 kW of its TRIO50 solar inverters on a landmark 1 MW floating solar photovoltaic test-bed in high population density, land-scarce Singapore, where floating solar panels are regarded a viable alternative. Due to the cooling effect of the water beneath the floating panels could also be 11 per cent more efficient than land based solar panels.

Local and Global NEWS SONNEN’S SOLAR TILED ROOFS: German solar storage provider sonnen has joined forces with roofing specialist Bristile Roofing to be the national supplier of solar-powered energy storage systems for homes using Bristile’s new integrated Solar Tile, which the company will launch later in the year. Bristile says many builders are looking to offer integrated solar systems as part of their standard offer. Chris Parratt, Managing Director of sonnen Australia, said “The new home market is going to be one of the biggest channels for solar and storage as it will be a prominent feature for home builders in their designs.” Under the partnership, Bristile will offer the sonnen AC Coupled modular system to the builder market and for the first time the new sonnen DC Hybrid range. These come in both single and three phase units so that Bristile can meet all types of electrical standards in new housing designs. sonnen has installed 700 all-in-one storage systems in Australia in the last six months, and over its first 12 months it anticipates it will install at least 1200 systems. (See page 34.)

AT THE TIME OF WRITING, the Queensland government had ruled out support for funding the Adani rail line from the Galilee Basin to Abbot Point, saying it will not administer the loan. (Possibly something to do with risking tens of thousands of jobs on the reef versus employing several hundred at the coal mine?) For its part Adani has delayed its final investment decision on the Carmichael coal plant.

NO SURPRISE HERE, the US is “not in a position to join in the consensus” on the Paris Agreement on climate change. The Pope did try and influence POTUS, presenting him with Laudato Si, the encyclical on climate change the pontiff published in 2015. Also in the gift package from Pope Francis: a few of his other works on peace and economics.

DID SOMEONE SAY PREVENTION WAS BETTER THAN CURE? The Turnbull Government welcomes the release of online tool CoastAdapt developed by the National Climate Change Adaptation Research Facility to help local governments and other organisations understand and manage coastal risks. Around half of Australia’s population lives within seven kilometres of the coast, and coastal communities around Australia face the challenge of managing the effects of changes in the sea-level, such as flooding, erosion and shoreline recession.

Solar believers and achievers celebrate 25 years in action

EIGHTY SOLAR PIONEERS GATHERED IN SYDNEY a couple of months ago, each with 25 or more years in the solar industry in Australia or New Zealand. Their combined years of experience clocked in at an incredible 2129. The solar specialists spectrum spanned developers of the first solar cells, designers of the first inverters, manufacturers, academia, installers who worked on the earliest off-grid projects, people involved in the first gridconnect system in Sydney, those responsible driving a set of standards for solar installations and more. The milestone event was organised by Lindsay Hart of Selectronic ably supported by Nigel Morris of Solar Analytics and Kathleen Ryan of Winaico.

Storage: when and where Industry projections are just that – an educated guess at what’s to come. But the potential of storage and its impact on the energy mix is attracting widespread interest and analysis due to the seismic shift in motion. In the Electricity Network Transformation Roadmap Energy Networks Australia together with CSIRO have presented the outlook to 2050 which will see up to 10 million households and small customers with distributed energy resources like solar, storage, smart homes and electric vehicles by 2050. Also significant are the associated opportunities on the path to zero emissions. See report summary on page 16 or visit www.energynetworks.com.au/ roadmap. The state roundup reveals:

Standards Australia At the time of writing, Standards Australia was set to release draft national standards for energy storage systems (AS/ NZS5139). The draft national standards were likely to classify all lithium-ion battery storage systems as Fire Level 1, requiring them to be installed in bunkers and ensuring they can’t be installed in homes or in buildings attached to homes. This unnecessary restraint is not evidence based and is inconsistent with international best practice. It fails to differentiate between manufacturers who already comply with international standards and those who do not. Importantly, this draft standard is likely to add to public confusion about battery storage systems and will suppress demand for solar batteries. If this draft standard becomes a formal Standard it may seriously hurt the industry, leading to job losses and company closures. The Energy Storage Council is urging Standards Australia to take an evidence-based approach to battery storage.

Storage survey The Energy Storage Council is undertaking a comprehensive analysis of the Australian energy storage market. Funded by the Australian Renewable Energy Agency (ARENA), the analysis is likely to be released in late June and will be made freely available to the Australian community. Here we present some of the early findings.

Today’s battery market

FIRST TO THE SIZE OF THE SURVEY which is believed to be the largest storage market survey of its kind ever conducted: in all 628 surveys were carried out in the research that covered 36 manufacturers and 18 wholesalers, with more than 60 phone surveys. The full analysis of all the material gathered is in the early days, however market analysis by the Energy Storage Council outlines three scenarios for the uptake of energy storage – a high, medium and low growth scenario. Under the high growth forecast, almost 500,000 energy storage systems could be installed in Australia by 2020. Under the low growth forecast, around 100,000 systems could be installed by 2020. “The extent to which power prices rise and battery prices fall will be the biggest factors in determining whether Australia meets the high or low growth scenario, but you also can’t discount government actions,” ESC chief executive John Grimes said. “If governments, regulators and utilities make it harder for families to install solar batteries, it will be difficult to achieve the high growth forecast.“ The Energy Storage Council has already reduced its high growth forecast from 550,000 systems in 2020 to less than 500,000 systems due to concerns Standards Australia will release draft Standards for battery storage systems that are not evidence

Pricing is on everyone’s mind, and data suggest the average cost of batteries sized <35 kWh is $1016 kWh. But it’s no secret that system costs are falling. By late 2017 prices will be around $650-$1500 kWh. Return on investment for storage will be reduced from 9.6 years to five years.

Batteries on trial: the early verdict Lithium-ion battery performance test – early results ITP Renewables (ITP) is conducting independent performance testing on commercially available lead-acid battery technology and competing lithium-ion batteries. Funded by the Australian Renewable Energy Agency, the purpose is to verify battery performance against manufacturers’ claims and the desired outcome is to better inform energy storage system investors, to facilitate further uptake of renewable energy. LEAD-ACID (PbA) battery technologies have been used in stationary energy storage applications for decades. In recent years, however, new technologies have appeared on the market, and the range of options for back-up power provision and/or renewable energy storage has increased significantly. In particular, manufacturing of large format lithium-ion (Li-ion) battery cells for electric vehicles (EVs) has improved the cost and performance of Li-ion battery packs rapidly, and there is now increasing interest in using this technology in stationary applications. Nevertheless, particularly in remote applications where reliability is critical, energy system designers and end-users have been reluctant to transition to this new technology. In part, this reluctance is due to a long-history of over-stated manufacturers’ claims, which are often underpinned largely by lab-based tests run at a constant temperatures and which lack independent verification. The purpose of the testing is therefore to verify claims made by manufacturers about performance, integration, and installation of lithiumion battery packs, and to disseminate the results to the public. To achieve this ITP is independently testing the performance of six major Li-ion battery packs, an ‘advanced’ PbA battery bank, and a conventional gel VRLA (PbA) battery bank, side by side in hot daytime and cool overnight temperatures, similar to what they would be expected to face in real-world conditions. Testing takes place in a climate-controlled enclosure at the Canberra Institute of Technology. Battery cycling has now been ongoing since August 2016, and will continue until the end of July, 2019.

Testing procedure The batteries under test are: 1. Kokam (Nickel Manganese Cobalt), produced in Korea; 2. Sony (Lithium Ion Phosphate), produced in Japan; 3. LG Chem (Nickel Manganese Cobalt), produced in Korea; 4. CALB (Lithium Ion Phosphate), produced in China; 5. Tesla (Nickel Manganese Cobalt), produced in Japan/USA;

Figure 1. Measured capacity as a percentage of nameplate capacity

28 WINTER 2017

6. Samsung (Lithium Manganese Oxide), produced in Korea; 7. Ecoult UltraFlex (Advanced Lead Acid), produced in USA; 8. Exide Sonnenschein (Lead Acid), produced in Germany. The key objective of the testing is to measure the batteries’ decrease in storage capacity over time and with energy throughput. As the batteries are cycled they lose the ability to store as much energy as when they are new. To investigate this capacity fade, the Li-ion batteries are being discharged to a state of charge (SOC) between 5% and 10% (depending on the allowable limits of the BMS), while the lead acid batteries are being discharged to a 50% SOC (i.e. 50% of the rated capacity used). The advanced lead battery is being cycled between 30% and 80% SOC. These operating ranges are in line with manufacturers’ recommendations for each technology. A load-profile is being used which charges each battery pack over several hours (mimicking daytime charging from the PV), followed by a short rest period, then discharging over a few hours (mimicking the late afternoon, early evening period) followed by another short rest period. In total, there are three charge/discharge cycles per day.

Early results Capacity fade From the capacity data collected thus far, the Tesla, Sony, and LG Chem packs demonstrate capacity fade as expected. The long-term trends for the other packs are not significant enough to discern from short-term variability in capacity testing results. In particular, this variability arises because of instability and imprecision in the SOC estimation conducted by the BMS of some packs. The real trends will become clearer as time goes on. In the case of the Samsung and CALB packs, it is evident that the initial capacity exceeded the nameplate capacity (see Figure 1).

Efficiency Efficiency data shows greater variance than capacity results (likely due to SOC estimation inaccuracy). Nevertheless, in terms of round-trip efficiency, it can be seen that lithium-ion out-performs both the advanced and traditional lead-acid battery packs, despite lead-acid efficiency being higher than expected. It is clear that efficiency of >90% can be expected for either Li-ion NMC or Li-ion LFP chemistries, and it may be the case that a difference in efficiency will be discernible between the different li-ion chemistries by the conclusion of the trial. The variable results for the CALB pack can be attributed a known issue, and should not be taken as representative. More detail about the testing methodology and early results, including detail about charge acceptance testing and a discussion about how one of the lithium-ion battery packs has failed irreparably owing to improper lowvoltage protection provided by the BMS, is available at http://batterytestcentre.com.au/ In the near future, ITP will also announce a Phase 2 expansion of the battery testing, including the addition of several new batteries.

While they prefer to stay connected to the mains power in case of emergency, they want to be able to store their energy to use at night so they are not using the mains power after hours. The need for an energy storage system was growing. Having a solution that allowed both on- and off-grid capabilities enables them to mitigate rising energy prices and exercise control over power usage. While they have no plans to go off-grid immediately, Andrew and Anna are comfortable being in a position to go off-grid if necessary.

You get quality customer support that is different to that of other manufacturers.” Andrew remarked on the fact when people come to visit the property they can’t understand how LG Chem gets so much storage in such a compact box where ordinarily there’s a stack of lead-acid batteries.

Results Since the February installation Andrew and Anna have been anticipating lower power bills. Monitoring the data from the Selectronic inverter, Andrew believes they are already in credit over $200 for the power that hasn’t been used, and the power they have exported back to the grid. “I don’t really know how much power we’ve used locally, but there’s sufficient power going back to the grid to cover the cost of the service charge,” he said. But it’s not just about saving money for Andrew. “We’ve long held a sympathy for the environment, and in a lot of cases technology is now cutting edge – there’s a low carbon-footprint, feel-good factor to it as well, which is important.” As for their requirements to run their house independently when the grid goes down, Andrew continues to be impressed. “Matt has been monitoring our usage graphs and feed-in graphs – we had no idea that there have been three outages since we installed the battery. The battery and inverter are just working hand in hand.” Given the chance, Andrew says he would choose LG Chem all over again, saying “All that’s left for us to do is extend the system with another battery and more panels. It’s hard not to be overly effusive and enthusiastic about this project. “I’ve been so impressed with how it all came together and worked, it’s just remarkable. The installation is doing exactly what we required of it without going off-grid – it’s just taken us to a new level.”

LG Chem’s global storage sales KOREAN BATTERY GIANT  LG Chem recently advised it has now achieved global energy storage system sales equalling 2.6 GWh. The figure includes systems already installed and orders for installations over the next three years. LG Chem’s growth is expected to get a boost from its recent launch of the residential battery system the RESU series with capacities up to 9.8 kWh.  With the booming storage market the company anticipates the figure will fast grow in the next two years. BATTERIES FOR ELECTRIC VEHICLES: Late last year LG Chem announced the start of construction of an EV battery plant in Poland that “will turn the Poland EV battery plant into a mecca of battery production for electric vehicles around the world.” LG Chem’s Poland EV battery plant is the first large-scale automotive lithium battery production plant in Europe, and it will energise the electric vehicle industry across Europe. The plant is to start production in the second half of this year and once fully complete it will have the production capacity that can provide more than 100,000 batteries per year for pure high-performance EVs that can run up to 320 km once charged.  Once the Poland plant is in action, LG Chem will have established a global production system of four internationally located plants: home nation of South Korea, the US, China and Poland, securing the

production capacity of more than 280,000 batteries for pure highperformance EVs and establishing a foothold to become a global market leader.

The story of sonnen Bavarian company sonnen is Europe’s largest supplier of solar-charged energy storage systems, and recently established a base in Australia which has been identified as potentially one of its biggest markets. Head of sonnen Australia Chris Parratt tells us more about the uptake down under.

COMPETITION AMONG HOME STORAGE innovators is stronger than ever, but happily for German battery maker sonnen the interest generated by rival Tesla has actually been beneficial. Established back in 2010 – well before Tesla stormed onto the scene – sonnen is one step ahead with a proven product that has already been deployed in tens of thousands of homes. As a company spokesperson put it “People go online and start researching, and guess who pops up? We do.” Over in Europe sonnen is very much a household name, and the company rightly claims leadership of Europe’s battery storage market, having installed 20,000 storage systems across its main markets in just seven years. Testimony to the intelligent storage technology, sonnen has been listed ‘One of the top 50 Smartest Companies’ worldwide by Massachusetts Institute of Technology. Rather a nice accolade to include in testimonials. Now sonnen has high hopes for Australia’s residential storage market which it expects to be one of its biggest on the back of world-leading numbers of rooftop PV systems. To further its ambitions sonnen has struck alliances with partners Energy Matters, Zen Energy and True Value in Australia, and BDT in New Zealand, who started installing sonnen’s eco 8 – the eighth generation of the battery – in November 2016. By year’s end they had installed 300 units and by mid May this year a further 400 units bringing the total to 700 sonnenBatterie units in just six months. “We have sold more but we always state how much is installed rather than how many are in warehouses or how many deposits we have taken,” said Head of sonnen Australia, Chris Parratt “I say that because there are some poor battery systems on the market in their first version, there has been a surprising failure rate.”

Battery storage in Australia is forecasting to increase tenfold from 2016 to 2018 and sonnen’s Chris Parratt is poised for action

Watch this space: sonnenflat set for launch in Australia In early July sonnen will announce its sonnenCommunity and “sonnen flat” scheme which covers the cost of a household’s grid power in exchange for the household giving sonnen access to the power stored in the battery to draw down (along with hundreds of other batteries) and sell into the grid at time of peak energy use. By way of example 300 residential customers would provide about one MW of capacity enabling sonnen to bid into the market and cover the cost of free power. This ability, which Parratt describes as unique to sonnen because of its long life and capacity, will add to grid stability and energy security once battery numbers reach a critical level. The deal was introduced to the sonnen community in Germany last year and has since spread to other parts of Europe. Stay tuned for more on this enterprising deal that could further shake up the market. Sonnen manages all after sales service from its offices in Sydney, with technical and customer queries answered by Australian staff www.sonnensupportaustralia.com.au

Tech specs, stats and facts Manufactured in Germany sonnen’s “Plug and Play” storage system is an all-in-one package that includes the in-built inverter, home automation and intelligent software and batteries. A self-learning algorithm and data from the weather bureau processed by sonnen’s smart system can identify the best time for the battery to start charging. Customers are provided with an app for real time information on the system’s functioning. The Lithium-Iron-Phosphate (LifePO4) battery developed by sonnen comes with 10,000 cycles and 100 per cent depth of discharge (DOD) and is capable of supplying around 75 per cent of a household’s energy needs. The modular system enables customers to purchase 2 kWh to 16 kWh in 2 kWh increments and reaches best payback (typically six to eight years) when sized correctly for household consumption. The average size installed in Australia is 10 kWh. The single or three-phase system can be stacked together indefinitely. The largest is nine three-phase system stacked for 144 kWh capacity. The biggest uptake in Australia has been South Australia where households should achieve a payback of between 4.5 and six years.

STORAGE NEWS and PRODUCT UPDATES BUILD YOUR DREAMS: Earlier this year Chinese battery giant BYD which is best known as the largest maker of electric vehicles launched its new compact lithium-ion phosphate B-Box battery on the Australian home energy storage market. BYD hopes to compete with industry leader LG Chem and secure 20 to 25 per cent of the local storage market. A high-level delegation led by Senior Marketing Manager William Wang flew in from China to showcase the new technology at May’s Solar and Storage Show. The residential series ranges from 2.5 kWh to 10.0 kWh and the maximum capacity of the commercial series is 409 kWh. The battery’s thermal stability is said to enable a long lifespan and good return on investment and is described as “safe under extreme physical conditions”. The B-Box is available through four distributors including 360Energy‘s Solar360 who suggest BYD could gain from 25 per cent and 50 per cent of the local market that is on track to reach tens of thousands of installations. The B-Box renewable power capacity meets light to heavy electrical load usage, off-grid or on-grid, single phase or three phase application. It features the same battery technology in London’s fleet of 51 single-decker electric buses and Sydney airport’s electric bus fleet. BYD Electric Blu bus BYD also uses a lease model for its buses in some markets, where after the bus battery ends is useful life, it can then be deployed by BYD for stationary storage. Pictured right is William Wang who told Solar & Storage the hivoltage B Box technology was a finalist at Intersolar in Munich. He also talked about the 600-kilometre range of the battery now installed in buses at Sydney airport and around the world. We thought we’d let the picture below do the talking about BYD’s global reach.

Phil Livingston is pleased to be supporting innovation and education in the smart energy sector through API and the University of Queensland, saying “As the industry transitions to renewables and solar adoption continues to increase across the country, it is important to ensure this sector has a pipeline of highly skilled professional work force. We take it as our duty at Redback to aid in building the cleantech ecosystem to drive increased employment and competitive advantage for both Queensland as well as greater Australia. “We’ve already seen strong success in bringing UQ students into Redback, with a number of graduates choosing to take up positions as full-time employees,” said Livingston.

REDFLOW HAS TAKEN its largest single sale of ZBM2 zincbromine flow batteries, worth about $800,000, for multiple sites in the Pacific Islands. Redflow partner Vertiv (formerly Emerson Network Power) will provide the batteries for an energy storage solution being designed by New Zealand-based Hitech Solutions. Hitech is building advanced hybrid energy storage systems to provide reliable, remote power to multiple sites in a Pacific Island nation. This first ZBM2 order from Hitech supports the first stage of a multiple stage project. Redflow CEO Simon Hackett said this major sector sale recognised the unique advantages of its batteries and “This high-workload deployment in the tropics is ideal for our zinc-bromine flow batteries.”

IN A NETHERLANDS FIRST, a Dutch dairy farm has deployed six Redflow ZBM2 zincbromine flow batteries to store self-produced solar energy that can support its milk production with sun-harvested energy. Dubbed the Photon Farmer, the project aims to store solar energy for the farm’s use by using six 10 kWh ZBM2 batteries, the first Redflow deployment in the Netherlands. The 57.5-hectare family-owned farm currently stocks 110 dairy cows. Due to public importance, the European Union is co-financing the deployment, which could revolutionise energy supply by supporting businesses to become energy independent. Redflow Global Sales Director Andrew Kempster (pictured above right) visited the Netherlands this week for the project’s launch and said the ‘Photon Farmer’ had produced energy with solar panels for several years. “The battery project is seeking the best business model for future local sustainable energy production, including energy storage in a

battery,” he said. “Our zinc-bromine flow battery technology is well-suited for this project.” A prime driver for the project is to enhance the ability of farms to produce energy from renewable sources, leveraging large roofs with room for solar panels and even available space for windmills.

Inverter advancement leads the PV Industry SolarEdge founder Lior Handelsman is driving innovative solutions to gain a competitive advantage. Here he addresses solar developments arising from advances in inverter technologies.

FOR THE PAST DECADE, the solar energy industry has been focused on reaching grid parity, which occurs when solar energy generates power at a Levelised Cost of Electricity (LCOE) equal to the price of purchasing power from the grid. In many regions around the world, including in Australia, we have already reached and surpassed grid parity. This does not mean that the race towards lower LCOE has stopped. In fact, the industry is now competing against itself in order to provide more advanced and efficient solar energy solutions. As inverters have a significant impact on LCOE, we believe that a key to driving the advancement of the solar industry is inverter innovation. We can see the impact of inverter innovation by looking back at the past few years in which a number of new inverter technologies were

Pictured below: The PV system at the Harry Perkins Institute for Medical Research at Murdoch in Western Australia features the SolarEdge DC optimised inverter system and SolarEdge founder, Lior Handelsman (inset)

introduced that helped to advance the PV market. One particularly important innovation was the introduction of module-level power electronics (MLPE) to inverter topology.

By moving functionality to the panel level, this distributed inverter topology unlocked new value that was not previously accessible, such as more energy, high-resolution monitoring, design flexibility, and enhanced safety.

Inverter advancement In fact, this inverter advancement has even been called a potential disruptive technology for the PV industry due to its ability to offer value and improve the LCOE of systems. If the past few years are any indication of the future advancement of the PV industry, then the inverter can continue to drive the PV industry forward. There are many reasons why the inverter is key to this continued advancement, but the central reason is that the inverter acts as the brain of the system. As the PV system brain, the inverter is responsible for maximising energy production, smart grid interaction, safety functions, monitoring, storage, smart homes, and more. This means that when inverter technology advances, it not only improves the inverter

itself, but it also has the potential to impact all of the other additional functionalities it manages. In comparison, when improvements are made in another component, such as, a panel, the impact of this improvement is typically limited and may not necessarily affect other components in the system. Because inverter progress can help to advance the entire PV system, its improvement is strategic to the PV industry. As the functionality of inverters is expanding, inverters are simultaneously shifting towards digitisation which means that more of the DC to AC conversion processes is happening electronically versus mechanically. By entering the digital age, inverters have a faster trajectory for advancement and can now follow in the footsteps of other technological trends such as, smartphones, computers, and televisions. SolarEdge has made significant progress in digitising inverter functionality with its HD-Wave inverter. Not only has this had the immediate effect of increasing efficiency and power density of the inverter, but it will also allow the pace of inverter advancement to significantly increase compared to what we witnessed over the past 20 years.

and more. Lastly and most importantly, inverter manufacturers, like SolarEdge, are focusing their efforts on providing more innovative solutions to gain a competitive advantage in the market. This healthy competition will allow the inverter to continue to help PV proliferation around the world.

Enhancing performance The responsibility for improving PV systems mainly comes down to the inverter. So, the question remains, what is the industry doing in order to continue advancing the inverter? First of all, the regulatory organisations are placing additional demands on the inverter that manufacturers need to meet. A recent example is the tighter network restrictions particularly around phase balancing that came into effect in Australia on March 31, 2017, in addition to the requirement to include both PV and battery inverters in total phase and site generation capacity. From the demand side, homeowners and installers are requiring that inverters provide more value, such as monitoring, efficiency, reliability, energy automation,

Dunn who has seen the market take an interesting and dramatic shift with the gap between residential and commercial business widening. “Although Enphase is primarily focused on residential installs as a core value proposition we are also watching the market including multi-dwellings and aged care facilities with great interest, and developing smart energy solutions for many large retailers and distribution centres. Key to this is a favourable rate of return, maintenance factors and the levelised cost of energy,” he explained. Enphase is one of several companies that chose to launch its smart storage system in Australia, and for good reason, its work here represents about 70 per cent of Enphase’s storage achievements on a global

“The opportunities are great.” The business model involves 500 to 1000 installers across Australia and New Zealand on a regular basis and helping them configure the optimum sized Enphase system, with between one to three AC batteries sized at 1.2 kWh. Enphase analysis reveals bigger battery storage is not better. It’s a case of matching size with peak hour demand, and Dunn is mindful that work carried out to date reveals the average sized PV system is 3.6 kW.

Federal agenda Dunn is reluctant to endorse development of large battery banks and expansion of the snowy hydro scheme saying instead given the high levels of small scale, residential PV, more thought should be given to adding household storage as a means of smoothing some of the challenges faced by the energy generators. What about incentives? Enphase has found incentive programs overseas that are not managed well tend to backfire however a properly construed stimulus would be ideal “but it should not be outlandish and drive people to focus on price at lowest cost product which would lead to low quality product and poor installations.” Enphase continues to evolve and has launched the new sixth generation micro-inverter, and later this year its new AC battery will hit the market. *Stucco’s application and power purchase agreement is freely available from the Australian Energy Regulator’s website.

COMPANY OVERVIEW

Big plans for big plants Canberra based EPC Solar is fast emerging as a major player in the solar sector. Managing Director Daryn Stocks talks about EPC’s role in a variety of groundbreaking projects and some larger scale solar energy developments on the horizon.

BELOW: The 420 kW solar rooftop solar at Canberra National archives designed by EPC Solar, the company behind solar and storage, domestic sales and installations, micro-grids, solar hot water and solar air conditioning, solar financing, commercial solar and large-scale consulting

44 WINTER 2017

AUSTRALIA’S NEWLY BUILT National Archives Preservation Facilities in Canberra is home to 110 kilometres of shelving for vital documents that preserve the nation’s memory. The building is also home to an EPC-designed 420 kW rooftop PV system that will tap into the power of the sun for decades to come. The project is one of EPC Solar’s largest to date and has paved the way for a range of high profile PV projects that include the upgrade of the ACT Law Courts and the new Uniting Care Centre. EPC has also worked with the Department of Prime Minister and Cabinet to provide critical infrastructure diagnostic and support services to remote communities in Western Australian to support their transition to solar power generation systems. Over the past 18 months, the business has designed and delivered more than 120 renewable energy systems, ranging from household solar and battery systems, to commercial solar and LED lighting, to large-scale projects. At the helm is Daryn Stocks who brings years of design and installation expertise to the business, and has been recognised by the Australian Solar Council with a Master Installer Accreditation. Stocks also credits the technical skills provided by ACT firm Beast Solutions, which provides essential services in engineering, project management, project design, feasibility and optimisation. Together with DC Renewables, the EPC team is helping to deliver the ACT Government’s Next Gen program. The program aims to deliver storage systems to more than 5000 Canberra homes through battery subsidies of up to $3500 per household.

“Next Gen provides great momentum in the ACT and could be used as model for PV storage rollouts in other parts of Australia,” says Stocks.

New projects on the horizon EPC is in the process of closing several large commercial projects as well as a contract for a 28 MW solar farm, and is eyeing the large-scale battery storage with its partners as equipment prices continue to fall. On the back of their early successes, Stocks is progressing the expansion of the business with discussions underway with partners across the country, which will provide a wider footprint and greater resources to service large-scale projects. “Triple certification opens the doors for us and is enabling us to branch into other regions over the next six months, including Cairns, Townsville, Brisbane, the Gold Coast, Melbourne and also locations in Western Australia,” Stocks said. “We also have our sights on some inland projects, for large commercial and utility clients.” Although Stocks is unable to present more details of the projects until contracts are sealed he did explain all necessary resources had been locked in through joint ventures with ITP Renewables and German based R&L Solar who are eager to work with them on projects up to 100 MW. “Along with our business partners we are expanding to a national level during the next 18 months and will develop into a niche national player. We are well equipped to deliver the series of large projects we have in the pipeline,” said Stocks whose plans and aspirations extend beyond the near future. “During my fourteen years in the industry I have seen the solar coaster ride but I’d say the next five years are looking to be promising. That is, if it is managed the right way. People today are proactively looking at the potential of the solar and energy storage industry over the next five to ten years, and there is enormous scope for development. “I also believe the battery storage market will be secure during next ten years, and that’s why we are particularly interested in being involved in the design and deployment of large-scale projects and micro grids. These are the way of the future but we are well-position and geared up to take on the next wave of engineering procurement and construction (EPC) projects.” “I’m hoping that in five years or so we’ll attract international investors as it would provide us with greater financial capacity to develop ever larger solar farms and renewables.” www.epcsolar.com.au

GCL’s market grasp Last year Chinese solar giant GCL branched into energy storage and selected Australia as the location for the launch of its unique and popular battery range. One year on Solar & Storage chatted to Laid Sahraoui during his recent visit from GCL headquarters in Jiangsu, China.

UNTIL RECENTLY GCL was best known as a developer of large-scale solar farms. The world’s largest PV material manufacturer produces almost one third of the market’s silicon and 29 per cent of wafers that supply the world’s largest module makers including Yingli, Trina, Jinko, JA Solar, and Hareon Solar. The company has since carved a presence in the fast evolving storage market and last year introduced its sleek looking E-KwBe battery system sized at 2.5 kWh and 5.6 kWh respectively. The battery came with a touch of interior design: the lightweight stylish wall mounted system is available in five pastel shades that complement any décor. A form of functional wall art, you could say, certainly a talking point for visitors. It’s one year down the track, and according to Global Marketing Director Laid Sahraoui the stylish battery units which are available through GCL’s official distributor OneStopWarehouse have attracted widespread interest and achieved strong sales volumes. “We are also finding that there in an appetite in the market for a larger battery system. Many residential customers were buying two 5.6 kWh systems to cater for household energy demands so GCL Si has designed a larger, 9.3 kWh storage system,” Sahraoui explained.

“It’s a better fit for houses, and this larger system will come with improvements to the embedded technology.” The system (pictured) will come in three metallic shades and at a similar cost per kWh to the competitively priced 5.6 kWh storage unit that last year on release was labeled by installers a “game changer that brings storage to the masses”. The updated larger model is due for launch in the coming months following successful testing.

After sales service In other developments the company is introducing an after sales service for Australian consumers which will be directly managed by GCL company staff rather than OneStopWarehouse. “The key to ensuring customers are best served is a complete understanding by our after sales staff of all our systems and so we will be fully training technicians” Sahraoui said, “This will ensure they are equipped with the highest and best possible technical knowledge for all after sales service enquiries.” The move also reflects the fact Australia remains GCL’s biggest storage market, and was strategically positioned for GCL’s storage launch last year due to the relatively mature solar market, low installation costs and stable market demand.

Module sales GCL Global Marketing Director Laid Sahraoui with GCL battery kits

GCL’s global growth continues and the company is currently targeting more markets in Europe and also in the US pending the outcome of legislative changes to module imports. To cater for booming demand GCL is teaming up with Vino Solar in Vietnam to produce annual capacity of 600 MW in addition to the 5 GW manufactured by GCL at its factories across China. Module sales in Australia, Japan and India are also a focus of company operations. In just 18 months 500 MW of modules have been shipped to India where GCL has joined forces with energy giant Adani as well as others to develop large-scale solar plants in the nation where solar power is fast evolving. Demands are a little different in Japan, Sahraoui revealed. “Japan has a very specific rooftop solar market which demands customised modules to optimise system performance … due to this the modules which are destined for commercial and utility developments cost a bit more to produce.” In other news, GCL has teamed up with Tigo’s Smart Module performance box to increase performance in winter and on cloudy days.

COMPANY OVERVIEW

Solar circle 360Energy group is well known in the solar sector and continues to evolve along with the industry. In just seven years those associated with the business have been instrumental in installing up to 200,000 systems. In this first of a series, company founder Michael Anthony outlines the group’s activities and market drivers.

“Always be very clear on who the target market is and then develop a message to that target.”

WITH STRONG INTEREST in solar energy and the benefits derived from storage bubbling right across the country, 360Energy is on a roll and well positioned to secure an even greater slice of the action. Toward the end of last year the company experienced significant growth in the commercial sector with the average commercial installation for solar jumping from 20 kW to more than 50 kW. “This year that trend has continued and business are clearly concerned about energy costs so we expect the pace to gather,” said 360 founder Michael Anthony. Moving with the times and from small beginnings in 2010, the company has been well structured to cover all industry demands, from development, installation, management of energy storage and solar projects for itself and its partners. Previously known as Solar360, the enterprise has grown into the 360Energy group comprising My Community Energy, 360Storage, Projects360 and retail brand 360Energy. The suite of 360 businesses operating in the residential, community, commercial and industrial sectors deploy many of Australia’s most recognisable renewable energy products developed through commercial relationships with the big brands such as BYD and Risen. Michael Anthony explained the development as a means of “providing the end to end solutions across our business units to tackle the opportunities of our industries applications and provide a seamless solution to our customers.” Anthony – a savvy marketer – explained part of the successful strategy is “to always be very clear on who the target market is and then develop a message to that target. Working out where to deliver that message takes research and some trial and testing to get it right.” Staff of 360Energy group which has developed in all directions and now covers all aspects of the solar and storage industry

He identified industrial scale solar projects as another big mover this year, saying “We have been fielding inquires to our Projects business from across the country and this year we are expecting to turn soil in larger scale projects of around 100 MW to 150 MW. “Some we are helping with finance, others we are providing the entire EPC service and other part thereof. So in terms of dollars growth this will be the fastest growing market for us this year.” Unsurprisingly, much of today’s focus is also on energy storage, capturing solar energy and the software systems that drive and report on that. Anthony says building and operating embedded networks is not new but combining the latest solar and storage technologies wherever possible is a point of difference. 360 Group CFO Tim Blackmore explained that funding partnerships enable the company to integrate solar and storage solutions into communities at no upfront cost.

Software advances 360Energy has also been busy creating its own software systems that improve the efficiency and output of their energy storage systems by as much as 15 per cent. The software 360View delivers detailed analysis that enables demand management and trading of energy amongst their own systems, others, and the energy grid. Group Executive Chairman Chris Young said “Our software solutions also enable some of our more creative business models when combined with innovative finance and supply chain structures. We can use these structures ourselves or package up for others in the industry. “We offer the market an umbrella approach to a range of products and services, from EPC to Finance, supply chain to installation services … the implementation of community energy infrastructure and integrating storage systems and solar into embedded networks and building micro grids for regional or remote communities. We are able to deploy our own retail billing systems when required in these networks. Michael Anthony added “Understanding how the application of our technologies can release independence and economic development for families and communities is the core motivation for me, we want to share this knowledge.” In upcoming issues of Solar & Storage Michael Anthony will present his views on large-scale solar, storage sales, integrated networks, microgrids and more.

PD10 Laser-Guided Solar Pile Driver for the project. The project is designed using single axis tracking technology for maximum solar collection at the farm expected to generate 53,500 MWh annually and reduce greenhouse gas emissions by around 50,000 tonnes per annum. It will cover 93 hectares of land. Construction of the project includes 11,000 4m and 4.8m piles, and 79,000 solar modules. Each solar module is 3m wide and sits 2m above the ground. The project brief outlined that the 11,000 piles had to be driven approximately 2m into the ground with less than 5mm variance in spacing, vertically plum, and within height variances of 4mm. This had to be done at a rate of at least 120 piles a day.

CATON had experienced challenges with previous pile drivers, so a back-hoe and auger were brought in as backup in the event they were needed. However, when the trial began, the PD10 had put in all six piles, plum, within 2mm of spacing and within 1-2mm of height in the same amount of time that the auger bore had drilled one foot of its first hole. Precise pile placement is very important, as panel motors are later mounted on them. “CATCON was very happy with the results, they couldn’t believe the speed and accuracy,” O’Grady said. The PD10 has run smoothly since its trial and due to its speed, accuracy and reduction in pile damage, CATCON has purchased two PD10 Pile Drivers. O’Grady and Vermeer project support team

SOLAR PHILANTHROPY

Good things come to good people Solar philanthropy Rob Edwards of It’s Time Foundation is a serial solar philanthropist who was in full flight at this year’s Solar and Storage Expo. In a show of corporate social responsibility the Solar and Energy Storage Councils sponsored the It’s Time stand on behalf of Rob’s ongoing quest to fund rooftop PV at schools in Fiji that are installed by teams of able volunteers. The stand attracted enormous interest not just for the work of the foundation but also for the rather tricky but fun challenge whereby passers by were invited to float and land dollar notes in a shoe-box – quite a bit harder than it looked. Rob Edwards expressed his gratitude to the Solar Council saying “Of course, as a charity we cannot independently play that [expo] game. The solar conference was a great success for us with one of the important outcomes being follow-up meetings with a large organisation considering Its Time as the target for staff fund raising that they will match. “There were also many installers considering contributing each time they deliver a residential solar unit; some rotary clubs taking the concept back to their meetings; and offers of equipment support so lots of great and different ideas that should help us take things further.”

Rob also handed out “Heaps of business cards … and there are sure to be many more conversations in the future. We also had the opportunity to reacquaint with some of the people who have been generously supporting us for many years. “And you know what, I felt that many people enjoyed the conversations about solar making a difference purely for the greater good,” Rob said. Fellow It’s Time volunteer (and contributor to this magazine) Maja Gajic who recently gained her PhD also secured a few months worth of work following a discussion with Envirogroup. http://iitime.org/

Teddies to soothe the spirits Delegates at the Solar and Storage conference got to meet “little hero” Campbell Remess, the 12-year-old Tasmanian brainchild of Project 365. Each and every day Campbell stitches together one cute-faced, bright-coloured, furry teddy bear – 1000 to date – to give away at children’s hospitals and to comfort individuals going through tough times in their lives such as bullying. The story of selfless and kindness did not go unnoticed by Universe Solar who helped coordinate the installation of a 5 kW solar PV system at the Remess family home in Hobart. The system features 20 Enphase S270 microinverters and 20 Suntech Power 260 W PV modules provided by Enphase Energy and Suntech, Home Efficiency Group and Platinum Edge Electricals who contributed toward the installation and certification of the system. This project was managed on a pro-bono basis by Leeson Group and Universe Solar, with further donations received from the solar industry going toward funding Project 365 by Campbell who is now introduced as “Australia’s most internationally renowned teddy bear maker”. Campbell is pictured with (L to R) Nathan Dunn (Enphase), Peter Leeson (Leeson Group) and Peter Novak (Suntech)
