EU energy storage policy, regulation analysis, and market dynamics
GIGA Storage has reached financial close on the 350 MW / 1.4 GWh Albatross BESS in Lower Saxony, while ADS-TEC Energy says its application for a 1 GW / 4 GWh project in Baden-Württemberg is complete and awaiting a building permit.
BW ESS has acquired two 100 MW / 400 MWh standalone battery storage projects in France from Recurrent Energy, marking its entry into a seventh market with a combined 200 MW / 800 MWh four-hour portfolio.
Battery storage is expanding across Europe, but the route to bankability differs sharply between Spain, Italy and Germany, where capacity mechanisms, auction design and merchant price exposure shape project economics.
Since 28 July 2026, EU customs authorities and member-state market surveillance bodies have enforced implementing rules under the Battery Regulation requiring imported BESS to come with a UL 9540A thermal runaway propagation test report from an accredited laboratory.
Implementing Regulation (EU) 2026/1428 requires every battery energy storage system placed on the EU market from 1 October 2026 to carry a Digital Product Passport and a full life-cycle carbon footprint declaration.
Giga Storage secured €260 million in debt for its 350 MW/1.4 GWh Albatross project and signed a first-of-its-kind grid connection deal with Amprion, while ADS-TEC submitted final permitting documents for a 1 GW/4 GWh project and Kyon Energy commissioned its 137.5 MW/282 MWh Alfeld BESS.
Terna confirmed its main capacity market auction for the 2028 delivery period will be held on 21 December 2026, with cuts of up to 47.5% in the capacity recognised for new BESS, while Spain's Order TED/966/2026 still awaits its first auction calls.
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.
