On 26 June in Luxembourg, the European Commission, 22 member states, storage developers, manufacturers, and financial institutions including the European Investment Bank signed the EU's first Tripartite Agreement for Energy Storage. The goal: triple the bloc's storage capacity from roughly 55 gigawatts today to 200 gigawatts by 2030, with an interim target of 30 to 35 GW by 2028. The share of storage in peak power demand is expected to double from 5 percent to 10 percent.
The Commission has called storage “indispensable” to the EU's energy system. Without it, solar and wind output will increasingly be curtailed due to grid limitations, raising the risk of blackouts and greater reliance on imported fossil fuels. This comes as solar power hit a record 25% of EU electricity in June, led by Germany, Spain, and Poland.
National Targets and Persistent Hurdles
Several countries have already set national storage targets: Poland aims for 11,000 MW, Spain up to 5,000 MW, Austria 5,000 MW, and Bulgaria has a phased plan through 2028. Germany and other member states must submit their targets by the end of the year. Yet the agreement is not legally binding, and significant obstacles remain. Storage operators face double-charging, slow permitting, and grid-connection bottlenecks. The Commission will review progress annually through 2028.
This initiative is part of a broader push to address the growing gap between renewable generation and storage capacity. As Europe's clean energy surplus grows, storage lags behind, wasting potential power. The Tripartite Agreement aims to align industry, finance, and policy to accelerate deployment.
Financial backing from the European Investment Bank and other lenders is crucial. Without adequate financing, storage projects—especially large-scale batteries and pumped hydro—struggle to get off the ground. The pact also encourages member states to streamline permitting and remove regulatory barriers.
Critics note that non-binding agreements have a mixed record in the EU. The Commission's annual reviews will be key to holding countries accountable. If progress stalls, the bloc may need to consider binding legislation or financial penalties.
For now, the agreement signals a collective recognition that storage is no longer optional. As renewable capacity expands, the ability to store excess power will determine whether Europe can meet its climate goals while keeping the lights on.
