ERCOT’s battery storage fleet can play a crucial role during extreme winter conditions, but its own technical performance needs to be carefully managed.

Bigger, longer-duration projects and more sophisticated deal structuring are driving the energy storage industry forward, but a lack of common approaches from transmission system operators (TSOs) remains a challenge.

South Australia’s battery storage fleet entered a 4-hour AU$1,000/MWh (US$700/MWh) price event at around 90% state of charge during the Australia Day heatwave.

Three energy storage projects have reached key milestones, including pumped hydro, thermal storage, and geothermal alternatives to battery energy storage systems (BESS).

Lenders requirements for contracted revenues for BESS projects in the UK appears to have softened, an executive at investment firm Triple Point said.

More BESS news from across Europe, with ContourGlobal and Alpiq striking sizeable deals in Greece and France, Iberdrola putting projects into operation in Spain, and other project news in Germany, Poland, Denmark and Southeast Europe.

Germany’s four transmission system operators (TSOs) have begun procuring inertia services to help stabilise the electric grid as shares of renewable energy grow.

The global energy storage market is poised for continued expansion in 2026, even as supply chain constraints, regulatory evolution, and emerging applications reshape the landscape, according to Wood Mackenzie. 

A subsidiary of Juniper Green Energy has fully brought into commercial operation what the company claimed is India’s first merchant BESS project.

Fortescue’s battery intelligence platform has acquired analytics provider Zitara, and Drax has agreed to acquire optimiser Flexitricity.
