Welcome

John Grimes Chief Executive, Australian Solar Council and Energy Storage Council

IN EARLY 2017 we sit at the cusp of a massive transformation of the energy sector. Solar PV has already made stunning advances, and prices continue to fall.

Actually solar PV projects continue to win contracts across the world at prices lower than any other form of energy (including wind). At the same time battery storage prices are tumbling as electric vehicle numbers ramp up.

And policy makers are waking up to the fantastic potential of large scale pumped hydro storage. Cheaper solar PV and energy storage are happening at a very exciting time. A time when information technology and energy are coming together like never before.

Smart energy systems that optimise energy use, aggregate customers into ‘virtual power plants’, and provide the trusted billing platform for peer-to-peer trading.

The next 10 years are going to be absolutely transformative, and by 2027 smart energy will be widespread.

Clean, abundant, dispatchable energy will become a reality. Economics, and the power of the market are going to shift. The first half of 2017 marks the turning point. So strap in for the ride.

As an aside – markets are built on confidence. The carbon market maintains confidence by telling people it is here to stay for decades to come.

Actually, not true. I reckon it’s time to drop your carbon stock before the bubble bursts. I have.

Local and global NEWS Cheap, stable, zero-emissions network, Yes we can: ANU research shows an affordable and secure electricity network can be developed in Australia using 100 per cent renewable energy. The zero emissions grid would run on readily available solar and wind technology along with pumped hydro storage, removing the need for coal and gas fired power. Lead report author Professor Andrew Blakers said energy costs would decline from $93 per MWh in 2016 to $75 MWh from 2020 and New storage technologies and calculations reveal that with even a “modest amount pumped hydro use renewable energy of storage” and increased interconnectors, “energy generated during daytime to pump water to a dam which is channelled stability can match anything coal and gas can deliver”. into turbines at night.

Blakers however concedes bipartisan support for energy policy is necessary for the highly feasible vision to materialise. ARENA pumped $450,000 into the ANU study.

PV installations soar: During February 1.52 million small-scale technology certificates were created representing 12,405 solar PV systems, 4,616 SWH systems and 72.8 MW of capacity. The 2.98 million STCs created in the first two months of 2017 contrast well with the 2.25 million generated in early 2016. Year-to-date average STC creation now stands at 347,000, substantially above 2016 levels. The Green Energy Markets report also revealed commercial-scale capacity represented 26.7 per cent of February’s total. February PV installations are believed to be the second best since 2013 (after December 2016).

fallen 58 per cent in the five years to 2015 and are expected to continue to fall by a further 40-70 per cent by 2040. The levelised cost of electricity from renewable energy has reached grid competitiveness and in many countries undercuts all other sources of new generating capacity.

A record $US29.10 per MWh for a solar plant was recently set in Chile and record low bids for power from large-scale solar plants include: Dubai $US58.5/MWh; Peru $US 48/MWh; Mexico $US 45/MWh and in the US $US36-60/ MWh. Falling costs for large-scale solar PV means solar power is cheaper than new coal plants, and is increasingly competitive with wind.

Latest data from Australia’s National Greenhouse & Energy Reporting Scheme reveals pollution is up by 3.4 per cent since 2015 and has soared 7.5 per cent since the carbon price was ditched. As noted by the Australian Conservation Foundation “there is little incentive for big polluters to clean up their acts when they have a free ride to pollute”.

Indeed: pollution levels in Australia’s electricity sector, which generates about 35 per cent of emissions, rose 2.6 per cent on 2015 levels.

Good news: Solar costs have

Solar on a roll:

In 2015, Australia just made it onto the list of top ten countries for total solar capacity (in tenth place behind India and the UK). Australia’s total solar PV capacity is 5.44 GW across 1.58 million installations, the equivalent of more than one solar panel per person. In 2014-2015 there were >8,000 jobs in solar in Australia, with solar PV making up 53 per cent of renewable energy jobs. Large-scale solar PV takes off this year with more than 20 projects totaling >1 GW of capacity likely to reach financial close. All up 3.7 GW of large-scale solar is in the pipeline.

installed by homeowners across Hawaii’s idyllic islands enabling solar households to self-consume and to smooth large amounts of solar generation on the grid. The islands are tracking toward 100 per cent renewable energy by 2045 and a big part of the plan entails a scheme to manage the influx of solar generation at midday through commercial storage with minimal cost to utilities and ratepayers. Someone recently commented “Commercial storage is an industry that is just squeaking into existence”; however we say all signs show storage is roaring into action …

Yes to renewables:

A recent Essential Research poll found that almost two out of three people agree that more renewable energy is the solution to future energy needs, and a similar amount approve of Labor’s 50 per cent renewable energy target; just 18 per cent disapprove. Six in ten surveyed agree that climate change is happening and is caused by human activity; and 45 per cent believe that blackouts are due mainly to failures of the energy market in responding to extreme weather events (but 16 per cent still think they are a result of too much reliance on renewable energy). Although 45 per cent oppose building new coal fired power stations in Australia, a worrying 31 per cent actually support this.

GCL partnership in Vietnam:

Chinese solar giant GCL Poly, which last year successfully launched its lightweight home storage battery on the Australian market, recently invested in 600 MW of cell capacity in Vietnam through a partnership with Vietnamese maker Vina Solar. Up to 330 MW of the capacity will be for passivated emitter rear contact (PERC) high-efficiency PV cells. GCL says the move was important for growing its presence in the US and Europe and helps contain costs of cell manufacturing. In recent years JinkoSolar, Trina and others have set up production in Vietnam or Thailand.

Coal to go:

The Climate Council factsheet on Clean Coal states new coal fired plants would ultimately be more expensive than renewables and carry a huge liability through the carbon emissions they produce. Coal plants are largely considered uninvestable and are shutting down across the world, yet the Prime Minister continues to promote "reliable base load power with state-of-the-art, clean coal-fired technology". As the Greens say: taking money out of renewables and giving it to the coal industry is like trying to deal with the rise of the internet by subsidising the fax machine industry.

Renewables are fast laying the foundation for reliable, secure, emissions free energy that will be generated more cheaply than any other type of energy.

Here we look at some of the major advances and expectations.

and promote ‘clean coal’. But all signs are that their voices are fading against the ever-growing groundswell of support for clean energy across the community and business groups, investors, energy retailers and more. At the same time the renewables industry continues to strengthen and the reality is this promises to be a stellar year for solar and storage.

Solar and Energy Storage Council chief executive John Grimes believes the first half of 2017 marks the turning point, with cheaper PV and energy storage systems appealing to more consumers than ever before. He also says the next ten years will be “transformative” and that by 2027 smart energy will be widespread.

His views are supported by the numbers: as costs decline, battery storage installations will rise with more than 21,000 installations projected this year and according to the Climate Council around 1.1 million homes will have battery storage connected to their solar PV systems by 2035. The sophistication of energy storage systems connected to smart meters

John Grimes also observes that policy makers are now “waking up to” the massive potential of large scale pumped hydro storage.

The Prime Minister – who otherwise continues to demonise clean energy and state renewable targets – recently declared “Energy storage, long neglected in Australia, will be a priority this year [and] large-scale storage will support variable renewables like wind and solar. It will get more value out of existing baseload generation and it will enhance grid stability. We’re going to get on with it.”

New ARENA and CEFC funding rounds have been announced for large-scale energy storage demonstration projects, including pumped hydro, and Chief Scientist Alan Finkel’s review of the energy market (to be delivered later this year) has been asked to advise on the role of storage and pumped hydro in stabilising the grid.

Large-scale developments The potential for solar combined with large-scale storage is now being recognised with the Victorian Government seeking expressions of interest for a large-scale 20 MW battery storage facility in western Victoria to improve grid stability, and ARENA is funding the Lakeland solar farm and Kennedy energy park that combine wind or solar energy with battery storage.

Large scale solar comes into its own this year with enough solar to power 22 large renewable energy projects in the pipeline, adding 3700 MW and worth about $5 billion. Of these, 12 are part funded by ARENA.

The myth of ‘clean coal’ Which brings us to the oxymoron of ‘clean coal’ or more specifically “state-of-the-art clean coal-fired technology” baseload power spruiked by the Coalition.

The harsh reality is new (‘clean’) black coal plants generate in the region of 0.7 tonnes of carbon dioxide per MWh which is just 10 to 25 per cent less than existing plants. New brown-coal plants in Victoria and South Australia would produce an emissions rate of 0.93 which is greater than some of today’s black coal plants. Then there is the matter of carbon capture which costs from $5 to as much as $70 a tonne and comes with damaging long-term consequences.

Bloomberg New Energy Finance analysis finds this type of plant is the priciest and dirtiest source of mainstream electricity supply available, costing over their lifetime a minimum $134 MWh and possibly as much as $203 MWh. A rather unfavourable comparison to large-scale solar priced at between $78-$140 MWh or much less as now being seen across the globe.

“New coal is not cheap, it’s inflexible and unnecessary and it’s certainly not clean,” BNEF Australia chief Kobad Bhavnagri said. “It’s impossible to imagine a private market participant investing in such a project.”

plants and diversion of CEFC funds into the industry despite Section 62

Developers of large-scale solar plants say today’s economics already stack up nicely: the price of PV is falling, other input prices are falling, interest rates are low, and future energy and LGC prices remain high.

Developers can also tap into readily available products and technology.

Across the globe the cost of solar is reaching new lows; a record $US29.10/MWh for a solar plant was recently set in Chile and other low bids include Dubai $US58.5/MWh; Peru $US48/MWh; Mexico $US45/ MWh and in the US $US36-60/MWh. Falling costs for large-scale solar PV means solar power is cheaper than new coal plants.

of the Clean Energy Finance Corporation Act prohibiting investment of its funds in carbon capture and storage.

The move would also contradict the 2015 Paris climate deal that requires developed countries to have phased out coal generation by 2035, and a similarly worded OECD agreement.

The Climate Council factsheet on Clean Coal notes “New coal plants would ultimately be more expensive than renewables and carry a huge liability through the carbon emissions they produce,” and points out that even the Australian Energy Council regards coal plants as uninvestable.

Banks and investment funds are not interested.

the Climate Institute, the St Vincent de Paul Society, Business Council of Australia, Australian Aluminium Council, Australian Conservation Foundation, the Australian Council of Social Services and the Australian Council of Trade Unions joined forces to deliver the powerful message.

Australian Industry Group chief Innes Willox summed up by stating “We need both long-term reform for a market that delivers affordable, reliable and clean energy, and urgent shorter term measures.”

Metamorphosis The tide is turning; supporters of old polluting technologies are few and far between. Australia’s major energy companies are not interested in investing in new coal plants; nine ‘old’ coal plants have closed in recent years and doors soon shut on Hazelwood, Australia’s dirtiest plant.

CEFC’s report to the Finkel review stated policies to drive the longterm transition must be bankable and that new fossil-fuel generation in Australia would be unlikely to find private sector finance at an acceptable cost.

“The whole world is moving away from coal” the Climate Council factsheet states. “They are shutting down existing coal-fired power stations, and embracing renewable energy.”

CLIMATE COUNCIL STATE OF SOLAR

The Sunny state of Solar THE CLIMATE COUNCIL’S State of Solar 2016 presented an array of good news: solar power is booming in Australia and around the world; costs have reduced by as much as 60 per cent in just five years and large scale solar now costs less than new coal or nuclear power.

State of Solar 2016 finds this year will be significant for solar with the development of 20 large-scale plants with an additional 3700 MW in the pipeline; enough to power 600,000 homes.

Key findings: ONE Globally, solar PV power is surging on the back of scaled-up production and continually falling costs. Breaking 2015’s record of 50 GW added capacity, in 2016 across the globe more than 70 GW of new solar power capacity was added in 2016, led by China (34.2 GW), the United States

(13 GW) and Japan (10.5 GW). The solar sector employs 2.8 million people globally, outnumbering coal jobs. In the US, solar now provides twice as many jobs as coal.

TWO Solar costs are now so low that largescale solar plants are providing cheaper power than new fossil and nuclear power in many countries. Solar costs have dropped 58 per cent in five years and are expected to continue to fall by a further 40–70 per cent by 2040.

Electricity prices from new coal fired power stations could rise to A$160 per megawatt hour, while solar parks are around $110 MWh and are expected to reduce significantly in price over time.

THREE Australia remains a world leader in household solar. The cost of solar power is now well below the retail power prices in Australian capital cities, and continues to fall.

(The exception is the ACT which has the lowest

Australia adds more solar power every year than the combined capacity of South Australia’s recently closed Northern and Playford coal-fired power stations. More than 8,000 Australians are now employed in solar with solar PV making up 53 per cent of renewable energy jobs.

FOUR 2017 will be a huge year for largescale solar in Australia. Large-scale solar PV installations are already taking off in Australia in airports, mines, healthcare facilities and businesses. In 2017 more than 20 new large-scale solar projects will come online. A further 3700 MW of large-scale solar is in the development pipeline (roughly equivalent to three coal-fired power stations). Australia is expected to reach more than 20 GW of solar PV in the next 20 years, equivalent to about a third of Australia’s current total power generation capacity of 63 GW. FIVE A range of energy storage technologies will complement the growth of solar power providing secure, flexible power. Solar and battery storage for households and businesses is already gaining traction in Australia, with >6500 households installing the technology. Uptake is expected to triple in 2017. Large-scale developments such as the Lakeland solar and battery storage project and the Kidston solar and pumped hydro project demonstrate the potential of combining large-scale solar and energy storage technologies. Meantime the Victorian Government is seeking expressions of interest to build a large-scale battery storage facility in western Victoria to improve grid stability.

Storage growth spurt The home energy storage industry is relatively embryonic but set for fast growth this year and in the coming years. It is estimated that by 2035, around 1.1 million homes in Australia will have battery storage systems and numbers leapfrog to 10 million by 2050.

Back to today: we talked to a Canberra resident who recently installed storage and is finding it ticks all the boxes for performance and expectations, and is generating lots of energy as well as lots of local interest.

He said the house did not feel like a home unless it had a solar system!”

Because the battery generates a low hum they opted to install it on an external garage wall and find that friends and family are extremely interested in seeing and hearing about the battery’s performance and the impact on energy use.

The Jensens are succeeding in their bid to fill and discharge the battery each day to avoid importing power from the grid; with household use coming in at around 10 kWh per day on the system generating 18 kWh, about 8 kWh is exported to the grid earning credits of 7.5 cents per kWh as illustrated by Reposit’s smart system.

Serious storage progress Battery storage installations across Australia will increase rapidly on the back of high power prices, changing retail tariffs and falling battery costs.

Elsewhere in this magazine we report on the trebling of battery market in 2017 to more than 21,000, with 15 in 100 new solar installations opting for energy storage, and (another) seven in ten with solar wanting to add a battery to their existing solar system.

By 2035, around 1.1 million homes will have battery storage connected to their solar PV systems. The Energy Network Australia’s Network Transformation Roadmap recently found that by 2050, more than 10 million Australian customers could also own solar and storage and sell services to the grid.

International Renewable Energy Agency (IRENA) REthinking Energy states “new ways to store electricity will be a game changer for growing variable renewable energy generation”. Battery storage for electricity could increase from less than 1 GW today to 250 GW by 2030.

BNEF likewise forecasts a growth spurt for batteries and smart meters with year-on-year global commissioned capacity addition likely to double from 700 MW (in 2016) to 1.5 GW, almost all of it lithium-ion batteries. Battery prices have plummeted 70 per cent in five years and will drop at least 15 per cent this year. Last year a record $14.4 billion was invested worldwide in smart meters, well up on the $8.8 billion of 2015. But wait, there’s more: the market for smart meters could hit $19 billion in 2017.

18 AUTUMN 2017

Positive results Monitoring by Canberra based Installer SolarHub revealed 287.82 kWh was generated from February 1 to 17 and all up the system which fired up on 4 September 2016 had produced 3.73 MWh to February 17.

SolarHub Director Florian Geier added that ACT’s feed in tariff prior to 2013 was 50.5 c/kWh before being reduced twice and today it stands at 7.5 c/kWh, just enough to put the Jensens in credit.

They have been through just two power billing cycles, both positive but Sophie concedes that could change during Canberra’s short cold winter days when they switch on the electric heating system.

“My ideal is to be completely independent and off the grid,” Sophie said. “That would only be possible if the battery storage options improve, that is they held more charge.“

Environmental imperatives Sophie believes there is a subtle but serious shift underway saying those with a greater environmental awareness and in a higher socio-economic demographic, which takes in many in her area, can afford to and do invest in solar.

Also “Government support especially for small-scale solar producers is really diminishing and so now in the absence of incentives people with solar systems are much more focused on their own consumption.

“But as a family we are ethically and environmentally driven, that was the primary reason we installed solar with storage. It is all about sustainability not finance. I want the kids and the next generations to have a decent future, one that is less impacted by [the ravages] of climate change caused by the burning of fossil fuels.

“The biggest environmental contribution we can make is by adapting our own behaviours and I like to think I’m raising thoughtful and responsible consumers. I also believe that those who can afford a solar and storage system are all but obliged to install one.”

What about an electric vehicle down the track? “Definitely on the agenda, we will look at that in about five years.”

Let’s think … Huxley will be 16 years old by then, and quite likely busy checking EV performance ratings and specifications to determine which suits best for his L plates.

Catherine Tanna, EnergyAustralia

Lighting the way to a clean energy future In recent months EnergyAustralia has forged ahead with its $1.5 billion program to buy around 500 MW of power from renewable projects across eastern Australia, and has signed what is believed the largest deal of its type to date in Australia: a 13-year power purchase agreement for the 142 MW Ross River solar farm.

EnergyAustralia also put out the call for customers to join its new Brighter Council, a community in which members get to trial new and innovative energy products in their own home. The idea is to gather feedback to help create and shape new energy ideas and solutions before they’re launched to the rest of Australia.

“We’re providing customers opportunities to keep energy costs down, and at a personal level, the ability for families and businesses to be part of the transition to a cleaner energy future,” Tanna said.

Setting foundations

Large-scale solar

Meanwhile, 2017 looms as a pivotal year for Australia’s energy and climate change policy development.

EnergyAustralia maintains future energy policy requires a stable, national approach that clearly integrates the challenges of affordability, emissions reductions and reliability, and Catherine Tanna says any approach needs to start by considering impacts on the customer.

“We support action that addresses climate change at the lowest cost to customers while maintaining reliability of supply. We believe that the best policy framework is one that is national, integrated across carbon and energy policy, technology neutral and durable.”

As one of the country’s biggest generators of power from fossil fuels – EnergyAustralia operates the Mount Piper power coal power plant in NSW and the Yallourn brown coal plant which supplies about a fifth of Victoria's power – EnergyAustralia has made itself responsible for providing affordable, clean energy for all.

The company has moved swiftly on its $1.5 billion program to buy around 500 MW of power from new wind and solar energy projects across eastern Australia. In December EnergyAustralia secured a power purchase agreement for all the electricity produced by a 48.5 MW solar farm at Manildra in regional New South Wales.

A second announcement followed in February 2017: an agreement over one of Australia’s largest solar projects, the proposed 142 MW capacity Ross River Solar Farm in Queensland.

That same month, EnergyAustralia announced it had signed a long-term agreement to buy all the electricity generated by what will become Victoria’s first large scale solar project. Upon completion, the Gannawarra Solar Farm will have nameplate generation capacity of around 60 MW and will produce enough emissions-free, renewable energy to meet the electricity needs of over 25,000 Victorian homes.

EnergyAustralia has since signed a long-term

Well known solar inverter system developer Redback Technologies has been busy developing enabling technology that allows the grid of the future to take form through integrated hardware and software technologies that capture, store and manage solar energy.

In October last year, EnergyAustralia announced a $9.3 million partnership with Redback, which is an example of how EnergyAustralia is investing in the development of reliable, affordable and cleaner technology which puts the customer in control of their energy consumption.

The Redback Smart Hybrid Solar Inverter System combines a smart solar inverter, battery enclosure and intelligent energy management software into a seamless package, enabling customers to manage their energy consumption, save money, and reduce their carbon footprint.

Andrew Perry, EnergyAustralia Executive – NextGen, said EnergyAustralia is proud to be partnering with a company that’s driving Australian innovation in a way that’s good for customers and good for the environment.

“We know electricity costs are a concern for many local households. With the Redback Smart Hybrid customers can use their smart

All of these actions complement the company’s existing renewable energy program, with the rights to more than 460 MW of electricity from wind farms in New South Wales, Victoria and South Australia.

phones to monitor their solar energy, they can schedule major appliances including electric hot-water systems, air-conditioners or even pool pumps to run when there is excess solar power available. It means households don’t have to draw more expensive energy from the grid during peak times.

“Our partnership with Redback Technologies is about helping great Australian ideas and innovation get to market,” Andrew Perry said.

EnergyAustralia in partnership with Redback Technologies plan to make the second generation Redback Smart Hybrid available for customers in the first half of 2017.

Then there’s the feasibility study of pumped Australia with partners Arup Group and Melbourne Energy Institute. As an example of the project’s potential, a development with 100 MW of capacity and six-to-eight hours of storage would be like installing 60,000 home battery storage systems, but at one-third of the cost.

While talking about what’s to come is taking EnergyAustralia out of its comfort zone, the company is wasting little time making its aspiration a reality.

“We’re backing up our clean energy ambition with action. The sector is changing and energy companies need to do more than just adapt; it’s our responsibility to lead the way,” Tanna said.

BY 2030 WORLDWIDE BATTERY STORAGE for electricity could increase from less than 1 GW today to 250 GW. Here in Australia the outlook for storage appears stronger than ever, with 2017 shaping up to be the year that battery installations soar to more than 21,000 according to a recent survey. Elsewhere we read a mind boggling 50,000 households could install storage systems this year, and the Finkel review of the energy industry suggests, conservatively in our view, that within 18 years around 1.1 million homes will have battery storage connected to their solar PV systems.

Little wonder, given the rise in grid power prices, lower feed in tariffs and lower cost of storage products.

Now the Energy Storage Council is on a mission to find out what industry itself has to say about the rate of uptake and projections, based on real-life experiences of inverter and battery makers and suppliers as well as smart software innovators and suppliers. Members of the ESC covering all products and services will soon receive the comprehensive industry online survey and are urged to participate.

Why? The more information the ESC is armed with, the more realistic the assessment of storage today, tomorrow and the future, enabling industry participants to plan with greater confidence.

Full market dynamics will be presented in this magazine following the Solar and Storage conference in early May at the Melbourne Exhibition Centre where CEO John Grimes will deliver the valuable findings.

But we cannot overlook some ominous developments in the sidelines, namely the proposed new Standards Australia guidelines and recommendations which could effectively prevent battery storage units being installed inside homes or garages. The Energy Storage Council is working within the Standards Australia drafting process on behalf of all Members and is hopeful there will be a sensible outcome following the public consultation process.

The first Choice for Stored Energy Solutions

Storage news and product updates ARENA recently listed projects it has funded that feature largescale storage elements: • The AGL Virtual Power Plant (which will aggregate 1,000 household batteries in Adelaide to provide grid support); • Lakeland Solar Farm and Kennedy Energy Park (which combine battery storage with solar and/or wind generation); • The Kidston Pumped Hydro Storage Feasibility Study; and • The national off-river pumped hydro resource mapping study led by Professor Andrew Blakers at the ANU.

Australia’s first grid scale battery storage facility featuring a massive 20 MW battery will be built In Victoria’s north-west or south-west to enhance the performance and security of the grid. The Victorian Government says storage plays a vital role in integrating renewable energy generation and the facility will ensure reliability of supply and keep power prices in check, especially in peak demand periods, and will help modernise Victoria’s electricity grid.

Dawn of the age of storage: on the following pages we look at the 2017 Battery Market Report by Sunwiz that reveals the market is set to treble in 2017, to a point where 15 per cent of new solar installations will include energy storage.

Of those households that already have solar, the report finds that seven in ten plan to add a battery or two. Last year saw 6750 battery installations, or 52 MWh across 130,000 solar systems. And a reminder that in 2015 just 500 batteries were installed.

BNEF forecasts a growth spurt for batteries

and smart meters with year-on-year global commissioned capacity addition likely to double from 700 MW (in 2016) to 1.5 GW, almost all of it lithium-ion batteries. Battery prices which over the past five years have reduced 70 per cent will this year drop at least 15 per cent, triggered by Tesla’s Gigafactory and several other large manufacturing facilities coming on stream. Smart meters last year saw record worldwide investment of $14.4 billion, up from $8.8 billion in 2015; and the market could hit $19 billion in 2017, with 69 million smart electricity and gas meters installed led by Europe, Middle East and Africa. BNEF also notes Electric vehicles will break the million milestone. EV sales in 2016 came in around 700,000, accelerating 56 per cent on the 450,000 sold during 2015.

EVs greenest cars: The new midsize Hyundai Ioniq Electric tops the American Council for an Energy-Efficient Economy Greenest (car) List with the highest-ever Green Score of 64, followed closely by the BMW i3 (64) and coming in third is Toyota’s Prius Eco lithium-ion (62). Fourth is the Fiat 500E (62), followed by Nissan Leaf (60) and sharing a green score of 59 are Chevrolet Bolt and Kia Soul electric along with the new plug-in Toyota Prius Prime.

Ecoult’s home-grown battery storage technology is moving into international markets after forming a partnership with Exide Industries, India’s largest battery maker, to manufacture and distribute Ecoult’s energy storage system and technologies in India and South Asia. In related news Ecoult has been awarded $4.1 million in ARENA funding to support further development and innovation necessary to transition to a renewables based economy and help the company fully commercialise the UltraBattery and secure export dollars for Australian intellectual property.

Chief executive officer John Wood says Ecoult is well positioned to take its experience out to new markets, improving power quality and electricity access without the fossil fuel overhead. “The investments in projects here and the lessons learned from them pay off globally, taking Australian storage technology out into the planet’s most remote regions,” he said. “Today diesel is a fuel of convenience. Tomorrow it John Wood (left) and ARENA’s Ivor Frischknecht on the could be the fuel of last resort.” right

Storage news and product updates BYD

recently launched its new compact lithium-ion phosphate B-Box battery on the Australian market. 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 smart inverter can power household appliances that draw a larger load of up to 5 kWh such as fridges, freezers, as well as heating and cooling units. The modular design enables the battery to be stacked and connected to provide more power within a smaller footprint and offers a wide range of renewable power capacity to meet light to heavy electrical load usage, off-grid or on-grid, single phase or three phase application, with an off-grid backup function to cope with blackouts.

BYD marketing director Julia Chen said “Starting from this year, we are looking to get 20-25 per cent of the [Australian battery] market. This needs lot of work.” BYD distributor Solar360 is more optimistic, suggesting BYD could secure up to 50 per cent of the local storage market. On greater certainties, B-Box Energy Storage System features the same battery technology seen in London’s recently launched fleet of 51 single-decker electric buses. BYD (build your dreams) is one of China’s biggest private companies and the largest maker of electric vehicles; its electric buses

Canberra based Reposit is another local success story: chief executive Dean Spaccavento says their smart energy storage systems are helping the ACT grid transition toward 100 per cent renewables by offering Canberra residents “the most advanced battery control system in the world”. He was referring to the ACT government led NextGen Project Targeting 5,000 distributed storage systems across the ACT over four years.

Late March marks the launch of ARENA funded Project Consort with a focus on Bruny Island in which 40 customers totaling 200 MW of demand reduction participate in a test of consumer owned storage capability in offsetting the need for costly diesel generation on the island during peak holiday periods. The project runs until early 2019.

Reposit has also supplied systems to SAPN in its Adelaide trial in which 100 customers with subsidised storage systems and batteries are testing network support services. It is not dissimilar to the Networks Renewed project underway in Port Macquarie and Melbourne testing the ability of smart storage and PV control to balance voltage on the grid.

Australia's Battery Market set for eye-watering growth To gain a clearer picture on the extent of storage uptake in Australia Warwick Johnston of Sunwiz talked to the majority of battery makers and now estimates as many as one in five new PV installations in 2017 will include batteries.

FOR QUITE SOME TIME I'd dismissed the hype about the attractiveness of installing grid-connected batteries in Australia. Yes, everyone loves the idea of energy independence, and would love to give the middle finger to the electricity retailers who buy excess solar power at a fifth of the price they themselves charge.

But I thought there would be few people willing to spend tens of thousands of dollars to do so. On top of that, though Tesla had created a surge of interest, most PV retailers were struggling to convert that into sales, or had limited product supply options.

When I surveyed the market in April 2016, respondents reported that only although half of solar power enquiries were asking about batteries, barely 2 per cent of people who bought a solar power system actually bought a battery with it.

Back in April 2016, the median respondent forecast 850 installations nationwide in 2016, totalling 28 MWh; 75 per cent of respondents expected fewer than 5500 installations would occur last year.

Powering ahead My what a difference half a year can make! In the second half of 2016, more products came to market, Tesla announced a major price drop, and lo and behold batteries became an affordable option (for some).

Using SunWiz's PVsell software, the dashboard below demonstrates

that an Adelaide household can get a Warwick Johnston of Sunwiz 7-year payback on a 5 kW PV system with 13 kWh of storage, if they have moderately high energy consumption (25 kWh/day). In the process, they can generate 88 per cent of their energy needs, reduce their solar export by three-quarters, and reduce their grid draw by 72 per cent.

It’s no wonder that Australia is about to become one of the top countries in the world for battery installations.

But how do we know what's actually been installed? Whereas the STC incentive means SunWiz can track PV installations with a high degree of accuracy and deep resolution, no such data source exists for batteries.

Although distribution network operators may seem the natural focal point of data collection, our discussions with network operators revealed they are largely unaware of the true volumes of batteries that are being installed on their network.

“We are confident there will be at least a three-fold increase in 2017 [with] one in five new PV installations including batteries.”

In order to provide some transparency into what is otherwise a highly opaque market, SunWiz personally interviewed more than 60 battery market leaders. And by leveraging SunWiz's status as trusted independent solar analyst, we have been given unprecedented amount of information (most of which we must keep confidential), which has been compiled into a report that provides unparalleled insight.

Market insights The report shows: 1. 6750 battery installations occurred in 2016, up from 500 in 2015.

This means that 5 per cent of new PV systems included energy storage in 2016.

2. New South Wales and Queensland led installations in 2016.

3. Because most of the installations occurred in the latter part of the

This would mean one in five new PV installations in 2017 includes batteries.

4. There was a record volume of capacity installed in major projects, rollouts, and distribution network trials.

The full Sunwiz report provides a rich dataset of research, survey, and industry opinion that will inform the strategies of storage manufacturers, wholesalers and retailers for the year ahead. It includes full details of the volumes installed in 2015 and 2016, forecasts for 2017 and beyond, commentary and insights into market trends, details of battery pricing and financials, a listing of the top ranks of manufacturers wholesalers and retailers, and comprehensive coverage of the key news of 2016.

Redback inverter ensures Bundaberg resident can crack open an ice cold ginger beer (even when the power’s out) IN INNES PARK, Bundaberg, Queensland, retired salesman John Watson and his partner, Dianne Southwell, a horticulturist and permaculturist, have managed to minimise their power bills to zero in some instances, with credits on new power bills, and zero power outages.

They have an uninterrupted, solar power supply through daylight hours for their two fridges, a microwave, large hot water system and a bevy of other household items, including power tools.

Their solar supply also operates a pool pump for eight hours each day, with peak back-up battery power for night time usage.

By selling additional power back to the grid, credits are also appearing on their account, and to use John’s own words, “while it may not be a money making enterprise yet” the couple are steadily reducing their energy costs and transforming the way they look at their energy use.

Smart installation In March 2016, John and Dianne engaged AC Electrical to install their grid connect hybrid system with a Redback Smart Hybrid Inverter, 24 x

260w Suntech solar panels, and 2 x 2.4kwh Plyontech battery banks.

The couple had found a reliable solar power system that could be upgraded quickly if required, and which offered high power from backup systems. Their ultimate goal is to run their home with minimal costs, without compromising on their lifestyle or comfort, particularly in the harsh Australian summer.

They settled on the Redback Smart Hybrid Inverter because it met these needs and also came with a lower set up cost.

John explained, “While we considered other systems in the market, including Solarhart with Tesla Powerwall, Redback offered more features in a single package than the other competitors we investigated.”

Result!

After the initial set up, John and Di’s power bills have significantly reduced and other than being freed of soaring electricity prices, they are also benefiting from an independent replenishable energy supply, greater transparency over their energy usage and control over energy budgets.

John continued, “Redback Technologies and our installer worked with us closely to set up the system. After the initial settling in period and changing our storage hot water to a lower wattage element we are very happy customers!”

Offering guidance to other Aussie families looking to install a solar solution, he advises, “Don’t have unrealistic expectations of a return from it immediately, but rather, look at it as a long term way of reducing costs.

“I would also tell people to install the largest system they can afford and are allowed, which is consistent with your requirements, because this investment up front will pay off in spades down the track.”

Placing power back into the hands of consumers, Redback Technologies customers like the Watsons can analyse and control energy generation and consumption in real-time and reduce energy costs without sacrificing their day-to-day comfort and convenience.

It could just be the next generation Great Australian Dream.

32 AUTUMN 2017

Five tips and considerations for solar installers Redback Technologies National Sales Manager Tim Latimer presents his views on what’s important to installers as well as consumers of smart energy systems.

AT REDBACK we’re focused on investing in an upgradable solution that places the power in the hands of the Australians who generate it, to give them control over how it’s used. We create hardware and software solutions that are designed to optimise self-consumption with a lower upfront cost and a much faster return on investment than other systems.

With my background of more than eight years in the solar industry, dealing directly with wholesale distributers and solar installers on a national and international level, I’ve observed big shifts for consumers and installers alike.

Consumers are more educated on what they want and installers need to start listening. Here, I’ve shared five tips for solar installers to ensure they offer tailored solutions for their clients.

ONE: Consumers are looking for an

end-to-end solution In any purchase decision, customer are understandably looking to get the maximum features, specs and aesthetic with minimal effort and at the lowest price point. This is true across product types and is similarly applicable to solar storage and management.

Installers need to be equipped not only with the best products and services but also with the background knowledge to provide the best endto-end solution for their customers.

Many installers have an appetite for smart and integrated systems, wanting to provide all the benefits they can to their consumers. However others only look to provide a basic solution, rigidly sticking to what they’ve always recommended, without expanding their offerings.

Installers who hold their customers’ needs at heart will need to provide a tailored solution, enabling them to easily monitor their power usage through web apps on their smart phone, as well as ensuring a faster return on investment.

TWO: Performance versus integration Installers have two key considerations: how the product will perform and how it will be integrated and installed. When looking at performance, the difficulties lie in installers selling systems without adequately planning what storage solution is required for the particular scenario. How many batteries do they need? What will their peak demands be?

For a lot of installers they’re used to grid-connected solar, which doesn’t require a lot of planning, whereas we’re seeing an emergence in hybrid and battery storage that requires a greater understanding of energy needs prior to installation.

THREE: Smart technology is key Traditionally, installers could mount a system, turn it on and it would be the end of their role. The market is moving to a place where upgradable

systems are becoming the standard and we’re able to use data from a number of points to improve the usage experience. If there is an issue with the system it can be detected instantly, whereas in the past a customer would only become aware of the problem when the bill arrives or the power goes off.

Some systems now take advantage of the Internet of Things, connecting and controlling appliances in the home to optimise performance. The rise in machine learning technology means products are becoming more intuitive.

Installers are now working with IT experts to connect systems to the web and the cloud – their role is extended beyond the initial installation.

FOUR: Looking beyond Return on Investment Solar installers can sometimes hold false pretenses that the main motivation for prospects is return on investment. Although this is a fundamental factor, ROI isn’t all that concerns customers and it is worth taking the time to understand their needs before making any recommendations.

Some homeowners want to become independent from the utility grid or they might have a very poor connection because they’re remote. Others want a sleek, sophisticated unit or an upgradeable solution to future-proof them as technology innovations develop over time. Customer motivations can be purely environmental or they may want to support technology that is homegrown and developed in Australia. These should all be taken into consideration when helping customers choose a system that works for their needs.

FIVE: Commercial customers have different

needs Unlike residential customers, commercial customers have different drivers.

Financial drivers are stronger in commercial customers, as batteries and smart software can help reduce the cost of pulling energy from the grid at peak demand times. The necessity of energy security also plays a part – a shortage of power can be detrimental to business efficiencies. For example, commercial customers such as pharmacies might have critical supplies kept in fridges. If they lose power and their cooling systems drop off it can have huge consequences.

Home energy, energy independence Home energy management systems (sometimes referred to as EMSs or HEMS) are fast becoming a popular way to get the most out of solar panels and battery storage. What is an EMS, what benefit does it promise, and what features can they be equipped with? Here James Martin of Solar Choice assesses the characteristics.

PHYSICALLY, EMSs can take many forms. Some consist of a small box installed on a home’s electrical board, while others are embedded into a solar inverter or battery storage system. Still others may exist ‘in the cloud’, with no dedicated central hub.

An EMS has two core functions: • Monitoring: An EMS allows the user to see how energy is being consumed or generated in their home; at a minimum, it will display details about the ‘now’, but virtually all EMSs will also display historic data on demand. The granularity of monitoring varies; some systems show data in 15-minute chunks, while others may display it in fractions of a second. Ideally, an EMS will be able to monitor home energy consumption and solar PV system output as well as battery status.

• Control: An EMS should be able to control at least one element of the energy flows within a home. For some systems, this may mean diverting excess solar energy into a battery bank, while for others it could mean near total home automation to maximise overall energy outcomes.

Both monitoring and control are usually accessed through a smart phone app or web portal. Without control, the device is a monitoring system. Meanwhile, the main category of useful energy-related gadgets that have control without monitoring are hot water diverters.

EMS focus: Household, solar or batteries?

The first thing that sets EMSs apart from one another is the aspect of the energy consumption/production equation that the focus on. There are three primary focus areas: • Household energy consumption: An EMS that starts with household energy consumption does not require solar or batteries to operate; it can be installed and be useful in virtually any home. Basic systems allow users to monitor and manually (but remotely) control devices in the home. More advanced systems will also integrate with

34 AUTUMN 2017

solar and batteries if they are added at a later date.

• Solar PV: An EMS whose focus is solar PV will generally aim to maximise selfconsumption of solar energy, usually by switching select non-essential devices on and off.

Solar-focused EMSs are sometimes (but not always) built directly into the PV system’s inverter, and may be able to incorporate batteries at a later date.

• Battery storage: An EMS with a battery focus will work to shift energy around throughout the day to ensure that it is stored in the most cost-effective way as possible, taking into account the home’s tariff rates, anticipated solar energy production and household demand for the day. Several systems can also control devices within the home automatically. Battery-focused EMSs are often (but not always) embedded in the battery bank itself.

Other EMS features The exact features included in an EMS will vary. Some of the key features that EMSs often have are outlined below: • Device control: The EMS can remotely (and often automatically) control devices in the home. Consumers should be aware of which communications protocols are used by the EMS and which types or brands of devices it is compatible with.

• Tariff optimisation: For customers on a time-of-use (TOU) billing setup, an EMS can help to ensure that more energy is consumed during cheaper, off-peak periods and that less energy needs to be purchased from the grid during more expensive peak & shoulder times.

• Solar energy optimisation: Without battery storage or high feedin rates, solar energy should be consumed directly by the home to maximise value; an EMS should help the household to increase the

ratio of solar energy used directly vs the amount exported to the grid.

• Peer-to-peer trading: The ability to sell excess (exported) solar or battery energy to other households. (A ‘moderator’ – usually an electricity retailer – is necessary for peer-to-peer trading to be possible.)

• Spot price trading: The ability to access the wholesale electricity spot price on the National Electricity Market (NEM) in order to take advantage of high price events.

• Virtual plant functionality: Through collaboration with an electricity retailer or network company, EMSs may enable homes with solar and batteries to be integrated into the grid as an aggregated generation plant.

Storage news and product updates US battery maker SimpliPhi Power hopes to boost sales of its modular plug and play lithium ferro phosphate battery systems within Australia’s residential and commercial battery storage market.

California-based chief executive Catherine Von Burg was recently in Australia holding talks with key parties including suppliers, utilities and the Energy Storage Council.

Redflow

is exporting its zinc-bromine flow batteries to Asian countries where telecommunications have “leap-frogged copper lines into wireless telephony and broadband”.

The SA based company is targeting mobile telecommunication towers located in areas without reliable electricity supplies and is mindful of Indonesia’s 85,000 telecom towers, many of which require battery backup due to unreliable electricity supplies.

South Australia based Zen Energy’s One to watch: CWP is the name behind the mighty 260 MW Sapphire wind project near Glen Innes in northern NSW due for completion in 2018, and at a later date may develop a 20 MW solar farm. From what we understand CWP has teamed up with Belgian based IPS which developed Exeron, the hybrid energy controller that is unique in that it can draw energy from the grid or solar power or diesel back-up in a way that’s not been done before. The system was trialed in Saudi Arabia which indicates its suitability for harsh and remote regions, and as company management says, “microgrids are1all about resilience”. allgrid_energy_half-page_add_final.pdf 27/02/2017 4:02 PM

Big Battery Project is assessing the potential for between 50-150 MW of battery storage in Port Augusta. A 150 MWh battery would help stabilise grid frequency and voltage during times of power losses, they say, such as the catastrophic events of September 28 which left people trapped in dark lifts, unable to exit car parks, or stuck for hours in traffic.

The Energy Storage Council is concerned that important industry advocacy and policy activities could be derailed by diffused or unfocused competing messages.

It is fine to run a business, which ESC does to support its NFP goals, but when there is a lack of transparency, and roles are blurred, scrutiny is appropriate.

Well meaning and influential people and companies wishing to support renewables and energy storage should be aware of the facts before supporting a business which, of course, is simply aiming to maximise its

It seems that ESA simply comprises an event salesperson and a volunteer Advisory Board.

By contrast, with every dollar you spend with the not-for-profit ESC you not only get the marketing/sales benefit, but you also help support all our other important industry and advocacy work.

I hope this article provides some clarity to the many people who have expressed confusion about the role of ESA versus the Energy Storage Council.

COMMUNITY ENERGY

Building smart sustainable communities Founder of the innovative Brisbane start-up Our Energy Jim Chisholm promotes the benefits of a customer centric approach toward energy supplies.

Jim Chisholm of Our Energy is a champion of microgrid energy systems that are efficient, affordable and sustainable.

HOW QUICKLY can a normal everyday community become a smart sustainable energy community? Jim Chisholm, founder of Our Energy uses a combination of micro-grid technology and the development of customer centric solutions to enable communities of all sizes the ability to implement sustainable energy solutions and improve their energy efficiency.

Using Our Energy’s services, a community such as Newstead in Victoria could achieve its energy goal of being 100 per cent renewable within three years, removing the need for peak and off-peak demand management while also reducing residents’ electricity bills.

A customer centric community based approach is the key difference for Jim, who has 45 years of experience in the ever-changing electrical industry. When asked about his vision for Our Energy’s “Community energy for all our customers”, Jim explained that “we work with each community to develop a sustainable energy solution and then work individually with each customer in the community to improve their energy efficiency over time, thereby reducing both their energy consumption and cost. Our Energy strives to ensure that energy cost and usage are no longer front of mind issues for Australians.”

Designing a Solar City Jim is no stranger to the challenges of transforming regular communities into smart energy communities, having conceptualised Townsville’s Solar City Project. This pioneering project developed solar energy communities on Magnetic Island.

The goals were relatively simple; introduce a series of solar, battery storage, smart meter and energy efficiency initiatives to reduce greenhouse gas emissions, reduce “peak demand” and in turn save customers money.

The project involved installing 415 kilowatts of photovoltaic panels and engaging the local council and residents, resulting in a 10.5 per cent reduction in peak power usage and saving

residents more than $1.7 million in electricity bills (Townsville Queensland Solar City, 2013).

Through various successes such as this, Jim was eventually engaged by the State Government to form Queensland’s 30 year Electricity Strategy.

“… a clear sign that the international audience sees potential in Australia’s renewable energy sector.”

Team building

Community engagement

Combining his passion for renewable energy and its benefits to society with his experience managing projects that thrived when effectively engaging the community, Jim had developed the foundation upon which Our Energy was built. The first step was to build a team, so Jim called in a select group of executives with a wealth of experience leading Smart City initiatives. Leveraging experience, the team has forged a number of strategic partnerships with local technology companies and multinational corporations to ensure that Our Energy has the infrastructure and scale to transform the Australian Market.

The team was enormously impressed by the number of international organisations clamouring for a meeting, a clear sign that the international audience sees potential in Australia’s renewable energy sector. After a series of meetings in countries such as the US, India and Korea, Our Energy decided to engage partnerships with the likes of KEPCO and Samsung SDI due to their focus on continual innovation and experience in developing micro-grid technologies.

The micro-grid technologies allowed Our Energy to develop the basis for their smart grids, however Our Energy also needed flexibility to be able to offer customer-centric solutions.

They engaged with innovative local technology companies such as Elevare and Terrajoule to ensure that their range of products and the systems used are as efficient as possible, and tailored to meet the needs of the many varied communities that make up our Australian energy community. Elevare has developed innovative and leading edge technologies around solar and battery storage that delivers significant efficiency benefits whilst Terrajoule has developed an innovative modular solar thermal solution that can deliver renewable energy at any time of the day or night. These local companies ensure that Our Energy is at the forefront of research and development in the renewable energy sector.

In recent years, Our Energy has worked with a variety of retirement and aged care communities and universities across Queensland and New South Wales, demonstrating that their sustainable energy community model can work across a variety of applications.

They are also engaging with a variety of councils and a university hospital to develop

long term investments into research and development and hopefully the creation of a Centre of Excellence for Sustainable Energy that will attract and foster world leading innovative renewable energy research and development within Australia. If these initiatives come to fruition, Australia’s renewables sector certainly has a bright future ahead. www.ourenergycompany.com.au

PV THROUGH THE AGES

PV then and now, through the eyes of Trina’s Chief Scientist Dr Pierre Verlinden has clocked more than 35 years in the solar industry and in that time steered the efficiency – as well as the evolution – of PV cells. Here the International Technical Director of Trina Solar tells us about the vastly different expectations of the early days, and sheds light on China’s PV boom.

IT’S NOT OFTEN we meet scientists whose involvement in the solar industry dates back 38 years, however we recently caught up with Trina’s Chief Scientist Dr Pierre Verlinden who enlightened us on the early days of solar. Back in the mid ‘80s, he said, the global solar industry community numbered just a thousand or so primarily involved in research or as entrepreneurs, many of whom interacted on a first-name basis.

With worldwide PV capacity standing at just one megawatt the market was all but limited to the US space and satellite industry, however there was a vision to help third world communities without power to electrify.

“The main prospect for solar in the early days was in providing power to those without, climate change had not really entered the debate,” the Belgian-born Australian explained. “There was however some discussion over coal and oil reserves in the context of estimating the number of years supply.”

Another key difference during the 1980s was that solar cells tended to be manufactured in a warehouse style environment on single production lines lacking stringent air quality controls for particles and contamination; a far cry from today’s squeaky clean clinical environment in which factories such as Trina’s churn out in excess of 100,000 wafers every hour.

Solar’s early rise With the early focus on solar in space and the potential for third world off-grid communities, rooftop PV in city environs was barely on the radar.

“We had little idea that we would be installing PV on rooftops and generating energy so cheaply, we did not really contemplate grid Adelaide Airport’s 1.28 MW PV system, powered by Trina

connection,” said the electrical engineer who pinpoints the birth of rooftop PV as 1996, citing anything up till then as simply the gestation.

The first person Verlinden encountered with aspirations for residential rooftop PV installations was a Swiss entrepreneur whose strategy in 1985 was to target homeowners with two Mercedes cars in the garage - people who were slightly older, better cashed up and idealistic. But the PV industry had to wait until 2005 for take off, and is now poised to accelerate and eclipse all other forms of energy generation.

After Pierre Verlinden completed his PhD in Belgium he went on to Stanford University as Visiting Scholar before accepting a role in 1991 at SunPower, the then CPV start-up, working on a series of ground breaking projects for more than a decade. Following that he moved to Adelaide to work for Origin Energy before accepting a position with Solar Systems in Melbourne, while also founding PV technology consulting firm Amrock.

The year 2012 marked the move to Trina Solar.

Boosting efficiencies Fast-forward to today where from his offices in Changzhou, China, Pierre Verlinden is steering Trina’s research work at UNSW and ANU with ARENA on advanced PV technologies in his role as Trina’s chief scientist.

One research contract involves driving efficiencies in interdigitated back contact (IBC) solar cells which have been boosted to 24 per cent and there are aspirations for efficiency levels of 25-26 per cent.

“My original objective was to develop the best PV research centre in the world, and there we have produced the most efficient solar cell and

Background image: PV as far as the eye can see – India’s mighty 151 MW Neemuch PV plant is one of the world’s largest

I’m very proud of that, it cements Trina’s position at the forefront of technological development,” Verlinden told Solar & Storage during his recent visit to Australia.

He emphasises the important role of solar cell efficiency to significantly reduce the end cost of plant development through reduced requirements for cabling, labour, frames and more. “In that context efficiency becomes really important,” he explained, before reflecting that 30 years ago people were content with module efficiency of just 10 per cent.

China’s golden age of renewables Having now lived in China for more than five years Verlinden has witnessed the meteoric rise of large-scale PV in the country, saying “People don’t always comprehend the extent of China’s advances in renewable energy. Yes, two thirds of the power is currently derived from coal plants but they put enormous resources into renewables: In 2016 China installed 34.2 GW of PV and the plan is to install about 50 GW per annum from 2020 then 100 GW per year to keep up with anticipated demand.

“With a fast growing middle class consuming ever more energy, the needs of electricity in China over the years to 2050 is enormous,” he explained. “Electricity Generation capacity in China sits at 1.5 terawatts and the country will need 7.5 terawatts by 2050. If all that energy was generated from coal fired power plants it would represent a huge problem for the planet. New capacity has to be, and will be, renewable energy.

“In turn that [renewable energy mix] has to be absorbed by and worked in with the power grid and with storage, but does that mean pumped hydro or flow batteries at utility level, or compressed air, maybe even fly wheel or something else? And how do we combine PV and wind and hydro and ensure we still have a reliable grid?

“It’s a complex problem but we do know that PV and wind have the capacity to be installed faster than any other industry, especially compared to nuclear energy plants.”

Unstoppable solar Despite the challenges that lay ahead integrating China’s energy mix there is widespread support for solar PV there and across the globe.

“Solar PV is the people’s choice of energy, it is unstoppable,” Verlinden maintains. “People who don’t have PV today state that it is what they want in future. That said, PV is not the energy of the future but it is the energy of today. A home can be 100 per cent solar powered and disconnected from the grid. As the price of grid supplied energy goes up so does the payback on PV systems decline [so] it’s not all bad seeing energy price rises!

“Cost calculations and benefits of solar energy are a no-brainer – why bother with fossil fuel any more?” he posed.

“We need to put the wellbeing of the world before short-term economic or political gain. We need to work with all countries to promote sustainability.”

Dr Pierre Verlinden has successfully led a team of PV researchers and scientists to enhance Trina Solar’s PV technologies and produce several world records in cell and module efficiencies

Shifting market demand Founded in 1997 Trina Solar produces ingots, wafers and cells for module assembly and by late 2014 had shipped 11 GW of product.

Cumulative output had jumped to 15 GW by the end of 2015 and last year the company added another 6.5 GW taking the tally to more than 21 GW. The stellar run has secured Trina Solar’s place among Fortune’s top 100 fastest growing companies where it peaked at No 11 in 2011.

In the years to 2011 Trina Solar’s primary market was Germany along with other parts of Europe and also Australia but, with the monumental shift since then, up to 50 per cent of last year’s production was destined for use in China with the majority of the balance exported to the US, Japan, India (around 13 per cent) and Europe (less than 7 per cent).

Australia which today represents just a small slice of Trina’s market has until recently focused on residential and commercial installations, unlike China whose solar market is to date almost exclusively 100 per cent utility scale. Now residential and commercial applications are taking off in China and Pierre Verlinden says many low-rise dwellings in the country already sport solar hot water systems and that fast growth of rooftop PV is forecast.

In mid 2016 Trina diversified into residential storage systems and energy management through its offshoot TrinaBESS and Verlinden revealed that the parent company is currently reviewing other opportunities in smart energy systems.

Here in Australia Trina Solar is the number one PV panel supplier and is well known as the supplier of the University of Queensland’s iconic 1.22 MW rooftop installation comprising 5000+ polycrystalline Trina Solar panels matched with Power One inverters generating 1.85 GWh of electricity each year.

Trina is also the name behind Adelaide Airport’s 1.28 MW PV system.

“Solar PV is the people’s choice of energy, it is unstoppable. People who don’t have PV today state that is what they want in future … and as the price of grid supplied energy goes up so does the payback on PV systems decline [so] it’s not all bad seeing energy price rises!”

Spirit of Solar Goodwill rises again in Fiji Thanks to Its Time Foundation founder and philanthropist Rob Edwards with key support from volunteer Maja Gajic many schools in Fiji are now powered by solar systems rather than kerosene and diesel. Education standards have been raised along with quality of life for hundreds of islanders. But several solar systems were hard hit by Cyclone Winston last year which unleashed winds of 306 km/h throughout the islands. Here Rob updates us on developments to repair the infrastructure.

AROUND THE TRAPS

Around the traps WELL-REGARDED battery inverter specialist Selectronic which has teamed with lithium-ion battery maker LG Chem will soon be delivering flexible new energy storage solutions with integration between the SP PRO and RESU batteries.

The Selectronic/LG Chem RESU pairing will provide consumers with a solution to reduce their electricity spend and guarantee a steady flow of power during grid outages. The storage solution can be added to both existing (retrofit) and new solar installations.

UK BASED SOLAR DEVELOPER Island Green Power and Australian outfit Overland Sun Farming are soon commencing construction of three 100 MW utility-scale solar farms near Mildura in Victoria. Each one of the farms will constitute the largest solar farm ever built in Victoria and the total output will be 320 MW. The parties agree economic conditions are right for investment in large-scale plants: the price of PVs is falling, other input prices are falling, and future energy and LGC prices remain high.

46 AUTUMN 2017

The integration of LG Chem’s RESU series with Selectronic’s world-class inverter has gone through significant R&D and field testing by both companies to ensure Australian consumers get the best solution.

Technical Director of Selectronic Ken Scott said “We’ve been in the industry for a long time, and are careful to put out the right solutions and partner with the right companies.

Working with LG Chem was a good opportunity and a good fit for Selectronic.”

Solar customer demographics Jeff Sommerfeld has studied trends in solar consumer demographics over the past seven years and here he shares some of his findings.

UNDERSTANDING AUSTRALIAN CONSUMER UPTAKE of solar technology over the past decade will provide important insights into how they will respond to emerging technology such as batteries.

A study of solar PV uptake in South East Queensland over the past decade by Queensland University of Technology (QUT) academic Dr Jeff Sommerfeld has identified important population characteristics of consumers acquiring solar.

He said there was limited academic research into consumers and solar PV adoption and much of the

information on Australia was undertaken before the surge in solar PV adoption in recent years.

Over the past decade the profile of Queenslanders acquiring solar PV has changed significantly from previous studies which identified solar PV as being mostly acquired by people with higher incomes and tertiary qualifications, Dr Sommerfeld said.

"In fact, the highest uptake of solar PV systems is now coming from families, those on low-incomes and with homes of three bedrooms or more.

lower incomes had higher rates of solar uptake than for inner city university educated people on higher incomes.”

“The other important feature of the research was it identified important linkages between population characteristics that help to identify the profile of persons acquiring solar PV.”

Key findings The key findings were: • Being over 55 years old was a significant explanatory variable in solar PV uptake; • Having a three or more bedroom home was significant; • Families were more likely to adopt solar PV making the family composition of households as an important variable.

“More importantly, the research identified that people in outer suburbs with lower levels of university education and on lower incomes had higher rates of solar uptake than for inner city university educated people on higher incomes,” Dr Sommerfeld revealed.

“What this research found was the profile of people has changed as more people acquired solar PV. Being better educated and wealthier were important characteristics in the past but this has now changed.”

Research processes The first stage of the research was undertaken by mapping solar PV adoption during the period from 2008 to 2014 and comparing it to key population characteristics.

When this was placed on a map and colour coded, Dr Sommerfeld said it showed three key rings: an inner city zone with the lowest solar PV uptake; a middle ring with medium levels of solar uptake; and an outer ring of middle to low income suburbs with the highest levels of solar uptake.

The findings prompted further research which used statistical programs to model the data and examine linkages between the demographic variables and how these changed during this period.

Three different methods were used to examine the same data and the findings were cross examined. Each study provided similar responses.

Dr Sommerfeld said the well-used Diffusion of Innovation theory helped to explain how consumer profiles changed over time when adopting new technology.

“The highest uptake of solar PV systems is now coming from families, those on low-incomes and with homes of three 50 AUTUMN 2017

Table 1 shows each of the categories and the characteristics of people within each category.

Dr Sommerfeld said when the theory was applied to solar PV uptake in South East Queensland since 2008, the change in characteristics of consumers could be better explained.

“People now acquiring solar PV in South East Queensland would be considered in the early majority of uptake of technology and the personality characteristics from the theory could provide insight into their expectations and how to market solar PV products to them,” he said.

“Similarly, the research provides potential insight into the current and future characteristics of people acquiring battery storage technology and other types of energy technology.”

The 50 MW Kidston solar farm is the first of six Queensland solar farms to be funded through ARENA’s competitive large-scale solar round destined to change the face of big solar in Australia. ARENA has committed $8.9 million and the CEFC confirmed $54 million in finance towards Phase One of Genex’s $126 million Kidston Solar Project 270 km north west of Townsville. The solar farm is expected to lead to the Phase Two development of a 250 MW pumped hydro storage project on the same site and creates a potential model for other disused mine sites.

In other significant developments ARENA is ploughing $16 million into three big solar projects in NSW that have secured $150 million in debt financing through the CEFC – its most substantial commitment to large-scale solar to date. With a total value of $230 million – and sporting more than 400,000 panels – the solar farms at Dubbo, Parkes and Griffith will deliver 110 MW (AC) and increase NSW large-scale solar capacity by more than 50 per cent. Project owner and developer Neoen has signed commercial PPAs with energy retailer ENGIE. Construction is expected to be completed by the end of 2017.

ARENA CEO Ivor Frischknecht joined Queensland’s Energy Minister Mark Bailey, project owner and developer Genex and CEFC at a sod-turning event at the Kidston Solar Projects.

Message for investors The CEFC’s first equity stake in a solar farm – and the first in a series of large-scale solar investments in Queensland this year – comes with the investment of $20 million in the $225 million Ross River Solar Farm near Townsville. The move sends “an important signal to institutional investors about the commercial potential of greenfield clean energy developments”.

And on related matters, The CEFC’s Clean Energy Innovation Fund recently staged its first Clean Energy Innovators Demo Day, providing innovative entrepreneurial companies and start-ups with a platform to showcase their technologies and business plans to potential investors. The Fund invests in clean energy businesses that have progressed beyond the research and development stage, but are not yet able to attract sufficient private sector capital.

52 AUTUMN 2017

Green funds for GreenSync To help lower capital costs in the decentralised energy model of the future, the CEFC has committed $5 million to innovative Melbourne-based GreenSync whose technology “acts like the brain and spinal cord of the smart grid, giving industrial and commercial sites, households and businesses access to the appropriate energy source … at the right time, improving reliability and penetration of renewable sources.” GreenSync’s software based decentralised energy exchange (deX) project was developed through ARENA’s ‘A-Lab’ initiative.

ARENA is providing $450,000 funding to support the $930,200 pilot project that involves Reposit Power, Mojo Power, United Energy, ActewAGL, ANU, the ACT and Victorian Governments.

In this section we introduce you to some of the key exhibitors at this year’s Solar and Storage Conference and Exhibition taking place on May 3 and 4 at the MCEC. (For more details about the Show see pages 12 and 13.)

AlphaESS

Technology WITH ITS MODULAR DESIGN, AlphaESS Storion series Energy Storage System includes a smart energy management system, multi-functional hybrid inverter for different application scenarios, and lithium-ion phosphate batteries (LifePO4) which come with high peak power and a long lifespan. Battery cells are housed in robust metal cans and an intelligent battery management system is integrated into every battery module to maximise battery efficiency and performance. All AlphaESS systems feature a plug & play modular design.

Battery capacity can be extended by adding PowerPlug and PowerBank.

All Alpha ESS products are German designed and quality controlled.

Service Innovation Alpha ESS provides cloud based services such as monitoring, remote control, and load shifting through web portal and mobile APPs that enable system owners to maximise their PV consumption or store low cost electricity and use during peak hours, with uninterrupted power supplies during grid outage. With its auto generator start function, Alpha ESS users can also go off-grid.

The company offers pay-as-you-go options spanning 10 to 20 years covering the full package: system supply & install, maintenance, service, and finance.

A calculator on the website facilitates user-friendly estimates of battery storage system capacity and the internal rate of return of installing PV and the energy storage system, along with estimated quarterly energy usage,

targeted self-sufficiency rate and self-consumption rate, estimated day and night time energy usage rate, peak and off-peak energy usage percentage, and the estimated annual energy production. Users can evaluate the rate of return of a future 20-year cashflow based on the solar power system installed, the estimated pay back period of investing such system and the related bill saving percentage.

“We tend to do things properly, and it is all about people,” says Dong Lin. “We are all builders of the company, therefore with the right people joining force, we can do everything.”

On the ground Last year Alpha ESS signed a strategic support sponsorship agreement with Shanghai Jiaotong University for participation in Solar Decathlon 2017 using its advanced household energy storage systems and technical guidance.

AC Solar Warehouse

GRANT BEHRENDORFF can see a future where the majority of solar systems installed in Australia use AC Solar technology that he says provides systems owners with a safer, more reliable and higher performing solution capable of managing energy production, storage and consumption.

The engineering technologist explains that AC Solar systems, which use microinverters operating at extra low DC voltages, were brought into the mainstream by Enphase Energy in 2008 and launched in Australia in 2013.

Today AC Solar Warehouse is the number one distributor of Enphase microinverters in the Asia Pacific region, “and with energy storage in the form of AC Batteries now available, AC Solar Warehouse can offer a complete energy management solution,” said Grant who conducts regular introductory and advanced installer training sessions around the country.

“Sometimes when we talk to installers about the benefits of microinverters over conventional DC systems or DC optimisers, we hear ‘well of course you would say microinverters are better, because that’s what you sell’ and we have a bit of a chuckle over this. We actually don’t think microinverters are better because we sell them, it’s actually the other way around: we sell them because we believe they are a better solution!”

managerial proficiency during his 25-year career with Ergon Energy in Queensland overseeing the installation of numerous renewable energy systems. He also managed assets in 33 remote communities in Queensland within Ergon’s Isolated Generation group.

For his part Grant has notched up more than 30 years experience in the electricity industry. For six years he led the widely respected Bushlight indigenous renewable energy project and managed a project adapting the Bushlight approach to remote village electrification in India, which collected the prestigious Sir William Hudson award, Engineers Australia’s highest accolade for Engineering Excellence.

Grant was Chair of the Alice Springs Solar Cities Consortium from inception in 2005 to conclusion in 2013, and is a Director of Alice Springs based consultancy CAT Projects. The string of achievements does not end there: Grant was named Engineers Australia National Engineering Technologist of the Year in 2007.

Surpass Sun Electric (SSE)

SSE in action Whyalla Solar Farm: Late last year SSE Australia's team met with key South Australian local and state government officials to officially launch the construction of the $200 million 120 MW Whyalla solar plant planned to be operative by late 2018. The project could potentially reach a capacity of 150 MW, making it one of the largest solar farms in Australia. It will also help the South Australian government meet its progressive renewable energy target of 50 per cent by 2025.

Electric vehicles: SSE which is at the forefront of EV technology has been ranked in the top 10 best Electrical Vehicle (EV) chargers providers and in 2016 was officially recognised as one of the most influential EV charger brands in China. “This recognition is a huge deal for SSE and cements our reputation as one of the most influential EV charger brands in China,” the media release reads.

56 AUTUMN 2017

SSE EV chargers are fast or slow charging, wall-mounted, portable, all-in-one, split or integrated and can be used to charge a range of domestic and commercial vehicles. They can be seen at Shanghai Pudong international Airport, where SSE China has set up 20 EV charging stations enabling 20 cars to charge at the same time; and at Shanghai CaoBao Bus Bay, China’s biggest public transport bus bay. SSE’s new energy vehicle charging and power supply systems will soon be available in Australia.

Glen Eira Sports and Aquatic Centre: SSE’s SPS 20-30 kW (commercial) solar inverter helped the Glen Eira Sports and Aquatic Centre transition to solar energy. The 384 solar panels on the roof of the centre make this one of the largest solar power systems on a local government building, and forms a vital part in the council’s energy efficiency plan.

Meeting Standards: SSE Australia is proud to be one of the manufacturers meeting Standards Australia new standard that came into force in October last year. Its SPS 20-30 kW inverter boasts a conversion efficiency rating of 98 per cent.

New large-scale solar consortium Key issues:

CPD PROMO

• Large-scale solar projects to be targeted • Broadspectrum and MPower to cooperate and collaborate • Binding MOU signed in Sydney in early February 2017 IN A TIMELY MARKET MOVE, Broadspectrum (Australia) and MPower Projects have formed a new consortium to target large-scale solar projects in Australia.

The consortium brings together two well-established organisations to target the expected future growth in large-scale solar projects. The parties executed a binding Memorandum of Understanding and will work together to jointly identify, pursue and construct large-scale solar installations in Australia.

Broadspectrum will lead the construction activities and MPower will lead the engineering and design activities, reflecting the strengths each party brings to the consortium.

MPower MPower provides distributed power solutions and products, with particular expertise in renewable energy, hybrid systems and energy storage solutions.

The company has a track record of designing and delivering innovative power projects in commercial and industrial settings and in challenging remote locations.

MPower’s reputation for reliability in critical applications spans grid connected solar farms; residential and industrial energy storage systems; hybrid energy systems for remote communities; mini-grids and precinct power; grid stability and cloud prediction technologies; and critical power systems for the military and oil and gas environments.

MPower has approximately 100 employees across Australia and New Zealand and is a wholly owned subsidiary of Tag Pacific Limited.

Broadspectrum has the capacity to invest, build, operate and maintain infrastructure underpinned by its strength of services to a diverse range of sectors. These capabilities are reinforced as part of Ferrovial, a global infrastructure services company with €12.9 billion market capitalisation and 96,000 employees across 24 countries.

Chief Executive Urban Infrastructure, Sandra Dodds said: “We have the experience in build-own-operate projects in the energy sector, and we look forward to using that expertise to deliver large-scale renewable energy infrastructure projects together with MPower.

“This new consortium reinforces our strategy to further expand our services in the renewable energy sector.”

MPower has an established track record as a power systems integrator, with a focus on critical power applications. MPower’s experience in the oil and gas and defence industries has in recent years been applied to the renewables sector where MPower has successfully completed many solar and battery storage projects.

Commenting on the MoU, MPower director Nathan Wise said that the collaboration with Broadspectrum aims to accelerate MPower’s growth in the renewables space by targeting larger solar projects than MPower has previously targeted on its own.

“MPower has a leading design and engineering capability that can be used across a greater range of projects,” he said. “With Broadspectrum’s decades of experience providing integrated solutions, the collaboration brings a whole new perspective to the projects we can tackle”.

Vale Dr Bill Parker In 1996 Bill founded Renew Editors and Writers and for three years was a partner in video production business Living In the Comfort Zone specialising in sustainability.

One of his proudest achievements however was his role as longterm director of Proteomics International, providing services to the pharmaceutical industry in drug testing and accreditation.

On the lighter side of life Bill played clarinet and saxophone, featured in TV adverts, was a CFA and also Greens Party volunteer, enthusiast of vintage sports cars, rowing too, and a spot of Morris dancing. Go Bill!

Solar sphere

THE SOLAR COMMUNITY recently lost one of its most colourful characters, Dr Bill Parker. A man of many talents, Bill was possibly best known as the long-term editor of Solar Progress (precursor to Solar & Storage) in both print and digital format. He led the content from 1995 right through until 2014, a remarkable run by a remarkable man.

But then Bill’s life experiences are as varied as they are unique.

The story starts with Bill the apprentice flute maker in 1960 in London.

After spending several years in the broader music industry he turned his attention to science and went to Helsinki University as a lab technician before accepting a position at London University as a senior technician with a microbial genetics group investigating the possible human genetic hazard of ultrasound.

Over the decades Bill picked up a string of qualifications including a Higher National Certificate in Applied Biology, Bachelor of Science in Applied Biology, Doctor of Philosophy (University of Western Australia) and Graduate Diploma in Media Studies.

Many of the activities listed above overlapped, but Bill’s introduction to the then fledgling solar industry came in 1989 when he took up the role of director and manager of Perth’s Solar Energy Information Centre, founded by Garry Baverstock, which provided information and practical examples of renewable energy and there he published the newsletter Helios.

Bill was very much a PV pioneer, being the first to install rooftop PV in WA “Not the best technically but kept up with the demand,” he said. “But then THE TREE grew. Directly to the north on property owned by absentee landlord. Inhabited by squatters. No pruning no felling. “ True to nature he took it in his stride.

Amid Bill’s colourful resume we noticed one of his earliest job titles in the 60s was ‘progress chaser’. Though we are not fully sure what that role with Plessey entailed, there seems to be a nice confluence of sorts in his role with Solar Progress in which he chased developments in the solar sphere, hunting down progressive people, innovators, early adopters and more.

Throughout his life Bill remained a passionate supporter of solar and mentored many young solar enthusiasts, all of whom benefitted from his tremendous breadth of knowledge.

In 2009 Bill became a director of the Australian Solar Council and in 2014 in recognition of his string of achievements he was made a Life Member.

One matter we only recently became aware of was Bill’s involvement with DAGS, co-founded with fellow solar stalwarts Garry Baverstock and John Barker. The ‘Dedicated And Gentlemanly Scholars’ evolved into a network of like-minded renewable energy and environmental specialists who regularly met up over a beer or three for a spirited debate.

Needless to say Bill will be sadly missed by fellow DAGS and his large circle of friends and colleagues, past and present.

Political advisor, shepherd and doctor

In honour of the Good Doc

Bill was enormously versatile, happy to turn his mind to anything and at one stage the microbiologist who often advised prominent WA politicians about technology enjoyed a short stint as a shepherd and ploughman on the outskirts of Perth before returning to academia and completing his post doctoral fellowship at Murdoch university on the feasibility of alkaline bauxite residue (which translates to red mud, we understand).

For the decade from 1987 he was proprietor of Parker & Associates, a private consulting firm in applied microbiology and environmental management related to public health.

The Board of the Solar Council is planning a long-term commemoration in Bill’s name and will be advising members about this at the 55th Solar Conference in Melbourne on May 3 and 4.

The timing is appropriate, for Bill had attended every single annual solar conference in the years from 1991 to 2014. Like we say, a solar stalwart like no other.

Once more, our condolences to Bill’s wife Ingrid, his other family members and his many friends, supporters and colleagues across Australia.

Finally, deepest gratitude from this writer to “lovely Bill” for leading the way.
