Australian utility Origin Energy has released plans to build a 700 MW battery at the site of a former coal-fired power plant in the Hunter Valley region north-west of Sydney. Origin has a target of ending its use of coal by 2032, and the proposed battery, which would become the largest in the world, would form an important part of its transition strategy, and the site has been chosen such that existing transmission infrastructure would be able to be reused. The announcement comes after French utility Neoen submitted plans for a 500 MW battery in western New South Wales (the same state as the Origin battery) in December last year, and the Australian Energy Market Operator has said that there are now plans for a total of 7,000 MW of battery storage across the country. (Australia’s main grid has a little over 50,000 MW of installed power generation capacity.)
