European Battery Energy Storage intelligence — updated daily.
Portugal launched two competitive procedures on 22 October 2026 for up to 1,050 MVA of grid injection capacity reservation titles for storage, split between 750 MVA of standalone batteries and 300 MVA of hybridised renewable-plus-storage projects.
Under implementing rules published on 26 June 2026, every BESS placed on the EU market must carry an IEC 63397-compliant battery digital passport from 18 February 2027, alongside full-lifecycle carbon footprint declarations and recyclability grade labels introduced on 1 August 2026.
Implementing Regulation (EU) 2026/1423, issued on 7 August 2026, adds updated CE-EMC testing, a new UL 9540A thermal runaway report and authorised-representative battery passport filing for BESS entering the EU market from 1 October 2026.
GIGA Storage reached financial close on the 350 MW/1.4 GWh Albatross BESS in Germany, while residential manufacturer sonnen filed for insolvency amid restructuring.
The European Commission has opened an anti-subsidy investigation into Chinese BESS, covering lithium-ion and sodium-ion systems, PCS, BMS and turnkey projects, with potential provisional duties ahead.
The EU has made EN 50703:2026 mandatory for BESS EMC, introduced a Battery Passport from September 2026 and drafted carbon-footprint reporting for 2027, raising the compliance bar for importers.
Italy will hold its 2028 capacity auction in December 2026 but has cut BESS derating factors by up to 47.5%, while Spain has created a capacity market framework but not yet launched auctions.
Portugal has launched two electronic auctions for up to 1,050 MVA of grid injection capacity for storage, split between standalone batteries and co-located renewable-plus-storage projects.
A seven-bank consortium is providing EUR 260 million in debt for Giga Storage's 350 MW/1.4 GWh Albatross project in Lower Saxony with commissioning planned for early 2029, while RWE and Borussia Dortmund commissioned a 3.7 MW battery at Signal Iduna Park.
Portugal's Greenvolt agreed to sell two completed 200 MW/800 MWh battery storage plants in north-eastern Poland to Malta-based A&R Investments, totalling 400 MW/1.6 GWh, with closing expected before the end of 2026.
Bulgaria doubled its battery storage capacity to roughly 6 GW in a year, supported by EUR 700 million in EU grants, and lifted power exports 62% to 3.5 TWh — turning the country into an unexpected storage leader while Greece lags.
The updated BESS safety standard EN IEC 62933-5-2:2026 was published in the Official Journal on 23 July 2026 and became mandatory on 15 August, adding thermal runaway propagation testing, liquid-cooling leakage tolerance and encrypted BMS communication to the CE marking path.
