Tesla South Australia battery partnership

A massive boon for South Australian solar today as Tesla’s Elon Musk and the South Australian government have paired with Neoen to create the world’s largest lithium-ion battery. The Tesla South Australia partnership will be a world first and comes off the back of a bunch of Twitter banter in March 2017 between Musk and various Twitter users (initially spearheaded by Atlassian co-founder Mike Cannon-Brookes), where he mentioned he is in discussions with the Premier about installing large scale solar in South Australia.

Tesla South Australia to create world’s biggest battery

The project will be 100MW (or 129MWh) and according to Musk on Twitter earlier in the year, it’ll be installed ‘within 100 days from contract signature or it is free’ – so we’ll be seeing the battery live and working this year! Jay Weatherill, the Premier of South Australia, was quoted as saying  “Battery storage is the future of our national energy market, and the eyes of the world will be following our leadership in this space”.

According to Nick Harmsen on Twitter, the battery will be built alongside Neoen‘s Hornsdale wind farm (currently 315MW), which is in Jamestown (mid-north South Australia). More details of the partnership coming straight from Heatherill’s office are embedded in the Tweet below:

The deputy CEO of Neoen, Romain Desrousseaux, said the project will highlight how large scale storage is now “commercially viable” and will also be able to provide “dependable, distributable power” – which was one of the main problems last year when South Australia suffered numerous lengthy blackouts, including last September when a freak storm damaged transmission lines. According to Weatherill and the ABC, the government had about 91 international bidders for the battery project, which could be used in the future to avoid load-shedding summer blackouts when electricity demand outstrips supply. Solar power (albeit as ‘energy storage’) being used to provide stability for the power grid is a new concept – and we’re very excited to see how it helps the festival state.

Tesla’s Musk was quoted today at a press conference at the Adelaide Oval as saying “It’s a fundamental efficiency improvement to the power grid, and it’s really quite necessary and quite obvious considering a renewable energy future”.

Tesla / South Australia Battery Partnership Reception

In an opinion piece for The Advertiser, Redflow CEO Simon Hackett has said South Australia’s 129 MWh Tesla project sets up the state as a world leader in battery storage. He also noted that it ‘confirms the integral role that batteries will play in the successful exploitation of renewable energy sources’.

The Rules at SA Power Networks have changed. SA Power Networks no longer allows *any* residential system (except for 3-phase) to produce over 5Kw REGARDLESS of any “limiting” tech in place. Unless you have 3 phase power or are off-grid, you can no longer go above 5Kw in SA. This means that SA is now a very BAD place to live if you want solar power. The rules are far worse than those in Queensland. This is not a rumor. The new Power SA rules state flatly that you cannot generate more than 5Kw on any “single phase” or SWER… Read more »
