A community-based program to encourage the uptake of solar and battery storage in Australian homes and businesses has been so successful that the promoters believe the battery storage sector may be in the early stages of mass-market uptake.
A bulk-buy campaign led by Suncrowd has attracted thousands of people at roadshows in regional towns in New South Wales in the last few months, and translated into what its organisers believe might already be the largest coordinated community energy project Australia.
So far, five community groups working together have attracted 3,500 people to events in Newcastle, Wollongong, the Blue Mountains, Shoalhaven, Goulburn and the Southern Highlands, delivering a projected 700kW of solar and 1.5MWh of battery storage.
Another 500 people turned up at a second meeting in Wollongong on Tuesday night and similar numbers are expected in the Blue Mountains tonight.
Suncrowd’s Chris Cooper says the response has been so strong that it shows that people are clearly ready for the next stage of the energy transition – by adding affordable energy storage and smart energy software to their solar system. It may even signal the start of the early “mass market” uptake of the technology.
Incumbent utilities should be worried. Firstly, they have long assumed that the uptake of battery storage would be a slow burn, and wouldn’t take off – apart from a few early adopters – until the “economics make sense.” When the economics do make sense, the big retailers assume that most consumers will go to a recognised name.
But Suncrowd’s Chris Cooper says many consumers aren’t waiting for the numbers to add up, or for the big names to get their act together. In New South Wales, this is being driven by frustration with renewable energy policy and the fact that the “60 cent-ers”, the 140,000 households on the solar bonus scheme, are about to lose their premium tariffs.
Community energy programs are also gaining traction. The “Repower” program that funds solar installations on local businesses has now raised nearly $500,000 for more than 300kW of rooftop solar, including a $140,000 fund raising that was met in less than 48 hours his week.
In Byron Bay, the community-owned renewable energy retailer Enova is also gaining traction, attracting more than 1,000 customers in its first few months of operation.
Even more worrying for utilities is that the economics of battery storage are close, very close. Bruce Mountain, from advisory firm CME, says the effective halving of costs in the second version of the Tesla Powerwall has made solar and storage cheaper than grid-supplied electricity in places like South Australia.
In fact, Mountain says the combination of solar and storage is now 25 per cent cheaper than the best retail offer in that state.
Cooper says that is not quite the case in NSW. Yet. “We are totally open about that – when you are just looking at bill savings, it is now making pure economic sense in certain household situations but not all.
“But what makes it still a rational decision,” he says, “is that many people are motivated by other “intrinsic” values – including energy independence, their support for clean energy, and their dislike of incumbent utilities.”
Suncrowd’s July campaign in Newcastle in partnership with Climate Action Newcastle was Australia’s first bulk-buy for energy storage, and had almost 200 participants adopting 250kW of solar and 660kWh of storage.
Cooper says the whole program has underlined some key highlights:
Cooper also notes that the release of the Tesla Powerwall 2 has eliminated interest in the LG 10kWh battery, and is neck-and-neck with the LG Chem 6.5kWh as the most popular storage offering.
Suncrowd has also developed some tools of its own, such as an online calculator, which assists households determine energy independence and bill savings. Since June, their programs have generated $50,000 income for community non-profit partners who assist in delivering the programs across NSW.

No mention of Hackett's Australian company Redflow which produces 'flow' batteries. Good to include a local product.
People should compare use cases, charge holding and durability of the storage solutions. How does the battery perform after 5 or 10 years? How long will the charge last? Do I need to use it everyday?
Battery systems perform differently depending on how and where you use them (cold/hot locations). It's not enough to compare price and KW/h.. It's a bit like people buying a speaker based on 'how many watts', there's more to it than that. It's all new so buyers should read up on the alternatives to get the best solution.
