Google to purchase 100% of output from the US’s largest under-construction BESS

Google has announced it will purchase all the power generated from the first two phases of Cypress Creek's Steel River Energy Center in Arkansas. The project comprises 1.6GW of solar paired with 1.9GWh of battery storage, with a potential third phase raising storage to 2.9GWh by 2029. Power will flow to the grid via the utility Entergy Arkansas rather than directly to Google's facilities, offsetting load from existing and planned data centres nearby whilst serving Google’s clean power procurement needs via the power purchase agreement (PPA).

US solar firm Nextpower enters energy storage market through acquisition of BESS maker Prevalon

Prevalon Energy, a US-headquartered battery energy stationary storage (BESS) manufacturer, has been acquired by solar and energy project software integration company Nextpower for US$365 million. Nextpower offers energy management systems as well as hardware for solar energy projects, and with this acquisition is looking to gain market share in the solar-plus-storage co-location market. Prevalon was formed in 2024 as part of a joint venture between Mitsubishi Power and EES, although Mitsubishi has been in the energy storage market since the early 2010s. It currently has 6.4GWh of energy storage deployed, predominantly in the US, Chile, the UK and Japan.
