The South Australia state government says it has received more than 50 proposals from energy storage developers keen to tap into a new $50 million scheme that will help navigate the local grid as it moves beyond a 50 per cent share of wind and solar and towards 100 per cent.
The state’s Liberal government is offering $50 million in taxpayer funds through its Grid Scale Storage Fund as it looks to expand its energy storage options, which have so far focused on the highly successful Tesla big battery at Hornsdale (owned and operated by Neoen), and the newly completed Dalrymple North battery on the Yorke Peninsula, and some household schemes,
The fund was formally launched in November and applications for projects ranging from big batteries, to pumped hydro, solar thermal, hydrogen and other forms of storage were due last Thursday.
Proposals must be for ready-to-build projects, and there will be no funding for feasibility studies.
Energy and mining minister Dan van Holst Pellekaan says more than 50 applications have been received, including from leading overseas developers. It is believed a lot of the storage proposals are looking to pair with renewable energy projects, indicating a growing confidence in that part of the market.
The storage proposals will be able to meet a range of different needs, including meeting peak demand and providing grid security and stability. The government says storage will make electricity more affordable, and boost reliability and security. Such projects will reduce the reliance on gas generation.
“The number of proposals and calibre of applicants highlights the gilt-edged opportunity to capitalise on SA’s abundant wind, solar and other renewable energy sources,” van Holst Pellekaan said in a statement emailed to RenewEconomy.
“The Marshall Government’s Grid Scale Storage Fund has succeeded in attracting energy pioneers from around the globe to continue the transformation of South Australia’s electricity network to a low cost, high reliability, low emission system.
“Grid scale storage is required so abundant renewable energy when it’s sunny or windy can be retained and then despatched to meet consumers’ needs.”
The grid-scale storage program is separate to the various schemes that are supporting household battery storage in the state. The government’s own Home Battery Scheme aims to install 40,000 batteries across the state and has so far installed more than 200, and received applications from a total of around 900.
That Home Battery Scheme has attracted interest from a variety of battery storage manufacturers who have established manufacturing operations in the state, including Sonnen, and Chinese battery developer Alpha-ESS and Canada’s Eguana Technologies.
Tesla is also working on a giant “virtual power plant” that aims to have 50,000 homes with solar and storage linked. The first two stages aim to install 1,100 while the final stage is still subject to finance and a retail partner. AGL is also completing a separate scheme with 1,000 homes linked with solar and storage.
Applicants to South Australia’s storage fund may also be able to dip into Australian Renewable Energy Agency funds.
ARENA has backed the Dalrymple North battery, and has also provided support for the 25MW/52MWh big battery being built at Infigen Energy’s Lake Bonney wind farm, and a variety of smaller hydrogen and distributed storage projects.
