Utility company Avista has selected projects as part of its request for proposal (RFP) process to identify new resources, including a 100MW battery energy storage system (BESS), for the Pacific Northwest, US.

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.

Ahead of the Energy Storage Summit Australia 2026 in March, we take a look at some of the key debates set to take centre stage at the event.  

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.
