Australia adds 1.2 GWh of behind-the-meter battery storage in December
More than 1.2 GWh of new behind-the-meter energy storage capacity was installed across Australia in December 2025 as households and businesses sought to take advantage of the federal government’s revised AUD 7.2 billion ($4.9 billion) Cheaper Home Batteries Program.
China connects world’s largest vanadium flow battery project
The GWh-scale long-duration energy storage project is expected to reduce curtailment in Xinjiang, a region of China with high solar and wind generation, and transmission bottlenecks. The flow battery installation is co-located with a PV plant.
Regulatory changes could shape Brazil’s 2026 battery storage auction
Brazil’s long-awaited capacity reserve auction for battery energy storage is scheduled for April 2026, following a year of rulemaking that expanded the expected supply volume and introduced new legal and regulatory constraints.
India’s energy storage market set for breakout year in 2026
After a record year for energy storage tenders in 2025, projects awarded since mid-2023 are expected to begin commissioning in 2026, reflecting typical development timelines of 18 to 24 months.
Corrosion-free bromine flow battery promises longer life and higher energy density
A new two-electron bromine chemistry sharply cuts corrosion while boosting performance, opening a clearer path for zinc–bromine flow batteries at grid scale.
Spain opens €90 million funding round for 7 GWh of pumped hydro storage
Spain will provide €90 million ($105.3 million) in funding for nearly 1 GW of pumped hydro projects, adding 7 GWh of long-duration energy storage (LDES) by 2035. Each project will be eligible for a maximum €50 million grant and all work must be completed by June 30, 2035.
Fox ESS rolls out stackable battery system
