EU storage targets established: Now the grid has to catch up How the EU’s Tripartite Agreement for Energy Storage will drive deployment with behind-the-meter and co-located battery solutions for faster connections

E arlier this year, parties from the public sector, energy-consuming industries, and clean energy developers signed a shared pledge on energy storage brokered by the European Commission. Signatories to the Tripartite Agreement for Energy Storage (European Commission, 2026) committed to lifting the EU’s annual pace of storage deployment from around 12GW per year to roughly 45GW annually between 2026 and 2028. The target is to hit the 200GW of capacity that the bloc’s own analysis says it will need by 2030 – more than three times the approximately 55GW installed at the start of this year. It is perhaps easier to understand the scale of the ambition in another way. Storage is expected to supply around 10% of peak electricity demand by 2028, up from roughly 5% in 2025 (pv magazine, 2026) . However, analysis of the agreement shows that the commitment does not yet fully live up to that ambition. Formal pledges submitted by member states so far add up to 30-35GW, some way short of the 45GW figure in the agreement text itself (Energy-Storage.News, 2026) . Bringing government, finance, and industry behind a shared commitment is exactly the kind of alignment needed to deliver large-scale battery rollout, so the agreement is a welcome signal. It points towards a more secure, flexible, and decarbonised electricity system that should ultimately become cheaper for the businesses and households who pay for it. However, as we often see with policy, this might not result in the solution we actually need. The agreement is explicitly non-binding,

yet its targets are aggressive. Turning pledges into energised assets will take considerable political will. Member states will need to move their regulatory frameworks quickly, as will the developers and financiers of pledged projects – a 2028 milestone is already looking uncomfortably close. To support the agreement, the European Investment Bank (EIB) is extending its existing €1.5 billion grids manufacturing package to cover storage-component manufacturers. However, while meaningful, it is modest when set against the scale of what a continent-wide storage build-out will actually cost. The scale and ambition of this agreement is exactly what Europe needs to help galvanise its deployment of storage and, in turn, support the deployment of more renewable power to its grids. There is no doubt that signing this agreement will attract private and member- state investment to get the required capacity built. What remains in question is just how fast this massive extra storage capacity can be connected to the grid it is meant to serve. Grid connections are now the main constraint For any battery project, the biggest constraint on how quickly it reaches the network is the availability of a suitable connection. Grid connections are highly contested across the continent. New transmission lines take years to plan, consent, and construct – years that are added to the energisation date of the storage projects waiting for them. The EU’s Grids Package and its accompanying Action Plan (distinct from the EIB’s finance mentioned above) aim to tackle this
