Japanese energy firm JERA says it will work with Fluence Energy and Lyon Group to develop large-scale energy storage projects in the Asia-Pacific region.

JERA, which operates around 66 GW of power generating capacity in Japan and 8 GW overseas, says it will work with Lyon and Fluence to explore opportunities for implementing storage solutions, focusing initially on Australia.

The three companies are planning to develop a portfolio of solar plus four-hour duration energy storage projects in Australia’s National Electricity Market. It has named Cape York in Queensland and Riverland in South Australia as sites for its first two projects.

Lyon, a developer of integrated utility-scale battery storage and renewables projects, built Australia’s first grid-connected solar PV and battery project. Fluence is developing a 30 MW energy storage project in Ballarat, Victoria.

“Australia is working to solve difficult ‘grid-in-transition’ issues at scale as they usher in the next generation electricity network that is cleaner, lower cost, and more reliable,” said Jan Teichmann, VP of Global Markets for Fluence. “More efficient electricity networks, more low-cost clean energy, and the highest reliability for consumers — these are the benefits we will be working to deliver with JERA across its operating fleet and through its and Lyon’s projects in Australia.”
