Last month, installation of a 30 MW/30 MWh battery at the Ballarat power station in Victoria was completed. That battery is expected to begin operations before next summer.The battery is owned by Australia’s renewables developer Edify Energy and Germany’s Wirsol and operated by EnergyAustralia under a long-term power purchase agreement, according to PV Magazine. Both batteries were paid for by a $50 million grant from the Australian Renewable Energy Agency and the government of Victoria, with each contributing $25 million.Although it was completed ahead of schedule, Edify Energy and Wirsol say that they had to overcome some unique regulatory and technical challenges to deliver the first battery storage system retrofitted to an existing solar farm. While the Australian government dithers and diddles about moving away from coal and toward renewables, the Australian states are filling the policy void and creating new commercial models for renewable energy and storage facilities in Australia.Asking people to change their behavior for a good social purpose seldom gets very far. Asking people to change their behavior to save money works a whole lot better. That’s what’s happening in Victoria today as well as in South Australia, Queensland, New South Wales, the Northern Territories, and Western Australia. The toothless, muddle-headed national government has made itself irrelevant to energy policy in Australia, proving once again that money is more important than ideology every time.More: 50 MWh Tesla battery commissioned at Australian solar power plant Australian solar facility gets Tesla battery retrofitlast_img read more
