Australia’s Victoria mandates new data centres match demand with own renewable energy and battery storage under new rules.

Nearly 21GWh of grid-scale BESS came online globally last month, of which around a fifth was in Saudi Arabia while the majority was in China. 

Residential battery energy storage systems (BESS) across California discharged more than 580MW of peak power to the state’s grid on the evening of 9 September 2026 via a Tesla-Sunrun VPP.

Utility PG&E has selected six new California microgrid projects for a US$30 million investment, while Massachusetts’ Department of Energy Resources is awarding US$40 million across 36 BESS projects.

RWE has taken a final investment decision (FID) on 400MW/1.1GWh BESS in the Netherlands with construction to start in due course, while Giga Storage has started building its 2.8GWh Green Turtle project in Belgium.

Nova Scotia Power has inaugurated three 50MW/200MWh battery energy storage systems (BESS) in Bridgewater, Waverley and White Rock, now Atlantic Canada’s largest battery storage facilities.
