US-based iron-sodium battery manufacturer Inlyte Energy has successfully completed a factory acceptance test of its first field-ready battery at its facility near Derby, UK, witnessed by representatives from US utility Southern Company.
A staggering total of 18GW/65GWh of large-scale BESS came online in China last month, accounting for a quarter of the total capacity deployed across the globe in 2025.
IPP Zelestra and utility EDP’s recent PPA deal for a solar-plus-storage project in Spain was the first of its kind in Europe and ‘moves the market forward’, a Zelestra executive told Energy-Storage.news.
A total of around 4.9GW/14GWh of grid-scale BESS entered commercial operations around the world last month, a 29% fall year-on-year owing to an unusually slow month in China.
Last month was the first time since June that both pre-application submissions and full planning consent submissions for grid-scale UK BESS surpassed 1GWh – just before NESO announced the results of its grid connection queue reshuffle.
We caught up with developer and IPP Greenvolt Power’s head of storage Antonio Montoto Rojo about the recent MACSE auction in Italy, where it won a contract for a 75MW BESS.
The US market is expected to be the largest source of revenue and driver of activity for Fluence in 2026, and a second battery cell deal with a domestic supplier is imminent.
The low prices and strict operational requirements in Italy’s recent MACSE auction for BESS have brought asset management and operational execution into the spotlight.
The battery storage industry’s race for higher energy density should be put into a site-level perspective, rather than focusing solely on larger cells.
