Engineering consultant Aurecon Group said in a statement last week the Hornsdale battery installed two years ago in South Austrialia has exceeded expectations for the way it has stabilized the grid and lowered grid related costs. So far, the Hornsdale facility has successfully met the challenge of three major system outages and reduced network costs by about $76 million in 2019, according to a report by Bloomberg. The battery has slashed the cost of regulating the South Australia electrical grid by 91%, bringing it in line with other regions in the nation, Aurecon said. Those savings are passed on to utility customers in South Australia.
Garth Heron is the head of development for French energy company Neoen, which owns and operates the Hornsdale installation. He says batteries smooth out fluctuations in the flow of electricity that can destabilize the grid. The Tesla battery is capable of responding to such frequency events more quickly than coal or gas fired generators and at much lower cost. “The grid has a heartbeat that needs to be regulated,” Heron tells Bloomberg. “I think there will be a faster battery roll-out than most people expect. They really are able to solve a multitude of problems.”
