30MW battery to create renewables-based mini grid in South Australia

The Australian Renewable Energy Agency says it is providing $12 million towards the $30 million cost of a major battery storage installation to be located on the Yorke Peninsula in South Australia and create a renewables-based mini-grid with the nearby Wattle Point wind farm.

The 30MW/8MWh large scale battery will deliver both network services and market services, and is the result of a lengthy study begun in 2014 called ESCRI (Energy Storage for Commercial Renewable Integration) by local grid operator ElectraNet, Worley Parsons and AGL.

It is designed principally to provide fast frequency response and help balance the local network, but it will also help reduce congestion on the Heywood interconnector with Victoria, because its placement means more power can be transported over the line. This should relieve constraints imposed by the market operator.

It will also have the ability to “island” the local network – pairing with the local 90MW Wattle Point wind farm and local rooftop solar PV as a local micro-grid to ensure grid security and so keep the lights on in case the network failures elsewhere in the state.
