EU signs first tripartite energy storage pact aiming for 35 GW capacity by 2028

The European Union has sealed its inaugural tripartite agreement on energy storage, bringing together 22 member states, storage developers, renewable operators, energy‑intensive industries and financial institutions. The pact commits the participants to add between 30 and 35 GW of new storage capacity from 2026 to 2028, raising the bloc’s total from roughly 55 GW to the 200 GW needed by 2030. Targets include increasing storage’s share of peak demand from 5 % to 10 % and expanding battery‑backed power purchase agreements to 4.5 GW. The agreement also calls for removing regulatory barriers, introducing cost‑reflective network tariffs and mobilising financing through the European Investment Bank, the European Bank for Reconstruction and Development and national schemes.

At the same Intersolar Europe exhibition, Chinese manufacturers announced a wave of orders totalling about 62 GWh. REPT BATTERO secured contracts across Germany, the Netherlands, Belgium, Austria and Eastern Europe; HyperStrong signed cooperation agreements for nearly 10 GWh, including 4.6 GWh for Italy’s Redelfi; Sineng Electric clinched partnerships in Germany, France and Turkey; and SOFAR obtained a 3 GWh order with INSOLAR.

Chinese battery maker EVE Energy also unveiled its new Mr. Big Family series, a 6.9 MWh system based on 702 Ah cells, and signed long‑term contracts for more than 13.5 GWh of storage capacity with partners such as SolarEdge and INFOWARE. Additionally, Tesla announced a $5 billion investment to build a 100 GWh Megapack storage network in Italy and the United Kingdom, beginning with five 25 GWh installations.

These combined policy commitments and commercial deals signal a rapid scaling of European energy‑storage capacity across utility, commercial‑industrial and residential sectors.
