Copenhagen Infrastructure Partners (CIP) has commenced construction on the Summerfield battery, Australia's first giga-scale battery project, marking a major milestone in South Australia's renewable energy transition.

The 240 MW / 960 MWh battery, located near Mannum, approximately 55 km east of Adelaide, will provide critical storage to improve energy reliability as the state advances towards its net 100% renewable target by 2027.

The project will feature Canadian Solar's e-Storage battery technology, with the company responsible for construction and operation under a 20-year agreement. Additionally, a 10-year off-take deal has been secured with Origin Energy, Australia's largest energy retailer, as part of its growing battery storage portfolio.

CIP's Jørn Hammer highlighted the importance of large-scale energy storage in ensuring grid stability and affordability. State Energy Minister Tom Koutsantonis emphasized the project's benefits, including improved reliability, economic stimulation, and the creation of over 100 jobs during construction.

With South Australia already sourcing 72% of its energy from wind and solar, the Summerfield battery will enhance grid resilience and support the 600 MW expansion of the region's renewable energy zone.
