EU Pledges 35GW Energy Storage by 2028: 22 Nations Sign Historic Pact
The European Commission unveiled its first-ever EU energy storage target on June 26, announcing a tripartite agreement signed by 22 member states that commits the bloc to deploying 30-35GW of new storage capacity within the next two years. The agreement brings together governments, energy storage developers, and energy-intensive industries in a coordinated push to accelerate renewable integration, curb curtailment losses, and reduce electricity price volatility across the continent.
Breaking Down the 30-35GW Target
The headline figure — 30-35GW of new storage by 2028 — masks an even more ambitious internal target of 45GW embedded in the agreement's full text. To put this in perspective, Europe's total installed storage capacity stood at approximately 35GW at the end of 2025, meaning the agreement effectively calls for a near-doubling in just two years. Storage developers must provide annual project pipeline capacity estimates, while energy-intensive industries commit to on-site storage deployment at manufacturing facilities. Member states are required to streamline permitting processes and provide targeted financial support.
The EU energy storage target also includes specific sub-goals: storage should meet 10% of peak electricity load by 2028, up from just 5% in 2025. Storage-backed power purchase agreements must grow from 1.5GW to 4.5GW, and commercial and industrial behind-the-meter battery storage must expand from 9GWh to 24GWh.

The European Investment Bank's Manufacturing Push
The European Investment Bank (EIB) will expand its existing €1.5 billion grid manufacturing package to cover energy storage component manufacturing, providing low-interest financing for European battery assembly lines, inverter production facilities, and balance-of-system component factories. This manufacturing support is explicitly designed to reduce dependence on non-European battery cell supplies and build a domestic storage manufacturing ecosystem capable of meeting the 35GW deployment target.
What the EIB Package Covers
The expanded EIB facility will finance battery cell and module assembly plants, power conversion system manufacturing, containerized BESS integration facilities, and recycling and second-life battery processing infrastructure. Qualifying projects must demonstrate at least 60% European content by value and commit to minimum environmental performance standards throughout the manufacturing process. The EIB estimates the expanded facility could mobilize an additional €8 to €12 billion in private co-investment over the next five years.
Industry Response: Cautious Optimism
Energy storage developers have welcomed the agreement's binding targets but flagged several implementation concerns. The 22 signatory states represent most — but not all — of the EU's largest electricity markets. Several Eastern European member states have not yet signed, citing concerns about grid infrastructure readiness and the cost of integrating large-scale storage into aging transmission networks. Industry associations have called for the Commission to release detailed implementation guidelines by September 2026 to ensure the agreement translates into shovel-ready projects before the 2028 deadline approaches.
What This Means for Global Storage Markets
Europe's newly codified EU energy storage target sends an unmistakable signal to global battery manufacturers and project developers: the continent is open for business at a scale that rivals the United States and China. Combined with the EU's existing renewable energy targets and carbon border adjustment mechanism, the storage agreement creates a regulatory environment where storage is no longer optional — it is structurally embedded in the bloc's energy architecture.
For companies across the storage value chain, the next 24 months will determine who captures the European market. The combination of binding deployment targets, EIB manufacturing support, and streamlined permitting creates a window for first-mover advantage that may not reopen for a decade.

The Path to 2028: Execution Risks
The ambitious timeline — 30 to 35GW in two years versus approximately 15GW deployed in the previous two — requires an unprecedented acceleration in permitting, financing, and construction. Grid connection queues across major European markets already stretch 18 to 36 months for large-scale storage projects. Supply chain bottlenecks for transformers, switchgear, and power conversion equipment could delay projects even if financing and permits are secured. The agreement's success will ultimately be measured not by signatures on paper but by megawatt-hours connected to the grid before December 31, 2028.
