A first project outside the US has been announced by Form Energy, the developer of a novel battery technology promising ‘multi-day’ duration energy storage.

In this US news roundup, updates on solar-plus-storage projects from Google and DTE Energy, Sunraycer, Invenergy and SRP, Idemitsu Renewables, and Clēnera.

The price of BESS has fallen steadily in the past few years, but recent events look set to slow or event reverse that trend at least in the short term. Video interviewees at last month’s Energy Storage Summit 2026 shared their views on the topic.

UK battery storage projects won a combined 1.8GW of capacity market (CM) obligations across the T-1 and T-4 auctions.

Australia’s New South Wales now requires 56GWh of storage by 2030, amounting to 40% more than projected just six months ago.

LG Energy Solution has entered into a US$4.3 billion supply agreement with Tesla, announced by the US government, while simultaneously upgrading its EV battery plant with GM for ESS cells.

A total of 6.9GW/17.1GWh of grid-scale BESS came online last month, as per the most recent figures from Benchmark Mineral Intelligence.

Terna, the transmission system operator (TSO) of Italy, has approved the grid connection for a 500MW/3GWh BESS project. Meanwhile several smaller projects have progressed across the rest of Europe.

Professor Tim Nelson has urged energy storage developers and market participants to actively engage in implementing sweeping market reforms.

The new edition of the UL9540A fire safety standard for battery energy storage systems (BESS) “establishes a new precedent in the testing and certification ecosystem.”
