Tesla’s energy storage business continued to grow in Q1 2025 even as profits and vehicle sales fell, but faces greater exposure to trade tariff risks than its automotive segment.

Three virtual power plant (VPP) programmes have been announced in California and Colorado. Two of them will use Tesla’s Powerwall battery. Another is attempting to change customer habits to save energy and money.

Netherlands-based startup Moonwatt plans to commercialise an energy storage solution for hybridisation with solar using two big technological deviations from today’s industry standard – we hear more from the firm’s CEO and COO.

IPP Clearway Energy Group has closed financing and started construction on its 1,280MWh Honeycomb battery energy storage system (BESS) portfolio in Utah, US.

Waller County, Texas, officials have approved tax abatements for Tesla to build its newest battery storage factory in the US.

The California Energy Commission (CEC) has published an environmental impact report (EIR) for a huge 4.6GWh co-located BESS and solar project spread across 9,500 acres of land in Western Fresno County under development by US-based independent power producer (IPP) Intersect Power. 

Tesla has inked an MoU with the Western Australian government to develop a battery re-manufacturing facility in Collie.

Tesla and Sumitomo Electric have both been selected to supply energy storage projects in Japan. Tesla will supply Megapacks for a BESS project while Sumitomo will deploy a 12MWh vanadium flow battery.

Tesla has reported record quarterly and full-year deployment figures for its Megapack and Powerwall battery storage products in its latest financial results. 

Project owners BSTOR and Energy Solutions Group have started building separate BESS projects totalling 440MWh of capacity in Belgium, following financial close, both of which will use Tesla Megapacks.
