According to The Australian Financial Review, large batteries are successfully helping remote townships and mine sites lift renewable energy use and cut fossil fuel consumption, signalling a likely broader use within the National Electricity Market in future than is currently appreciated.
Warrick Stapleton, LG Chem’s head of grid-scale batteries in Australia, said the performance of a battery installed in Onslow in Western Australia in May made the project "a blueprint for how remote communities and miners can balance traditional generation with very high penetration of renewables in a scalable way".
The Onslow project by WA's regional utility Horizon Power involves a 1 megawatt/500 kilowatt-hour battery system installed alongside a 1 MW solar farm at a substation, working alongside an existing gas and diesel-fired generator. The equipment, partly funded by US energy major Chevron, supports a self-supporting local grid that supplies a 900-person remote coastal township, gas plant workers and a salt mine.
