Multi-renewables developer Carnegie Clean Energy has won AUD3m ($2.4m) in government funding for a rooftop solar+battery storage project at a former General Motors manufacturing facility in South Australia state.
The grant will finance the design, construction, operation and maintenance of a microgrid featuring a 2 MW/500 kWh battery energy storage system and a 3 MW rooftop solar PV plant, to operate alongside an existing fleet of diesel-fuelled backup gensets.
The microgrid will supply the GM Holden site in Elizabeth, which an unnamed developer plans to redevelop as a business park.à‚
According to Carnegie, the PV system could be expanded to 10-15 MW if deployed across all of the site’s available roof space and the battery storage system can be expanded to tens and even hundreds of megawatts. à‚
Work will begin immediately on the design and microgrid connection, Carnegie said, and is predicted to finish by December.
The installation is planned to “provide a unique demonstration of grid-support services in times of peak demand”, Carnegie said, à‚ and “offers key advantages of traditional diesel-run gas turbines for grid support, offering significant savings in standby fuel consumption, greenhouse gas emissions, low maintenance, low noise pollution and faster response to grid support events.”
South Australian Premier Jay Weatherill said the project “is part of a wave of new investment in South Australia we have leveraged through the AUD150m Renewable Technology Fund announced as part of our energy plan.”
“Renewable energy projects like this also reduce demand on the grid during peak times, which puts downward pressure on power prices for all South Australians.”
Carnegie’s Managing Director Dr Michael Ottaviano added that his company is “fielding an increasing number of opportunities that historically were performed by diesel or gas turbines, for which battery systems are now increasingly competitive.”
Carnegie claims it is the only company in the world to offer “a combination of wave, solar, wind, battery storage and desalination via microgrids which are ideally suited to islands, off-grid communities and fringe-of-grid locations”. à‚
