22 EU countries sign first tripartite agreement on energy storage
The European Commission has secured the signature of the EU’s first tripartite energy agreement focused on electricity storage. The deal, signed on the sidelines of the Energy Council meeting in Luxembourg on 26 June, brings together 22 member states, storage system developers and manufacturers, renewable energy operators, energy-intensive industries, and public financial institutions.
The stated goal is to deploy 30–35 GW of new storage capacity in the short term, closing a gap that the Commission sees as a direct threat to the stability of Europe’s electricity system. Current installed storage capacity in the EU stands at around 55 GW, while the estimated need by 2030 is closer to 200 GW.
The agreement addresses a structural problem that has become increasingly urgent with the energy transition. Solar and wind power generate electricity intermittently. Without adequate storage, surplus energy cannot be saved for periods of high demand. The result is greater volatility in market prices, hurting both households and industry. European Commissioner for Energy Dan Jørgensen has described storage as “the missing link in the energy transition,” stressing that pairing renewables with effective storage systems is essential to stabilise prices and reduce structural dependence on fossil fuel markets.
The challenge is not only technical but also financial. Building large-scale storage facilities requires substantial upfront investment with long payback periods, in a market where price signals are not yet clear enough to attract private capital on its own. The tripartite mechanism aims to solve this by bringing all the key players – governments, industry, and finance – around a shared set of commitments.
A model born in Denmark
The idea of tripartite agreements did not appear overnight. It originated during the Danish Presidency of the EU Council in the second half of 2025. Denmark proposed applying to energy a model already tested in agriculture, where trilateral agreements between public authorities, private operators, and the financial sector had successfully unlocked structural investments that individual parties could not have launched alone.
The European Commission later formalised the concept in its Action Plan for Affordable Energy (February 2025), identifying tripartite agreements as a key tool to accelerate the transition without relying solely on direct public subsidies. In September 2025, Commissioner Jørgensen announced the launch of the first two sectoral tripartite agreements. The deal signed on 26 June 2026 is the direct outcome of that roadmap. The European Council of 19 March 2026 further accelerated the process by explicitly calling for faster integration of renewables and storage into the internal energy market.
Four categories, one shared commitment
The agreement organises commitments across four groups of actors:
Developers and producers of storage systems and renewables undertake to provide annual estimates of new projects and expected volumes, enabling the Commission and governments to plan support policies more accurately.
Energy-intensive industries (steel, chemicals, cement, etc.) commit to developing storage facilities on their own sites and to greater transparency on their electricity needs, giving private investors more certainty when assessing project profitability.
Member states pledge to remove regulatory barriers to storage deployment and to enable national regulators to set non-discriminatory grid tariffs that reward system flexibility. Where necessary, governments may provide public financial support under the Clean Industrial State Aid Framework (CISAF).
Financial institutions (national development banks, regional promotional banks, and the EIB Group) commit to pooling expertise and instruments to make storage projects more attractive to capital markets, mitigating risks that deter private investors.
The Commission will coordinate implementation and monitor progress annually until 2028.
Statements from Jørgensen and the EIB
Commissioner Dan Jørgensen described the agreement as a change in method as much as in objectives. “We have brought together governments – 22 member states have signed – developers and producers of storage systems, renewable energy developers, and energy-intensive industries, all of whom have signed a document aimed at promoting the deployment of storage technologies and increasing capacity that is urgently needed in the short and medium term,” he told journalists.
He added: “This is a new way of working: instead of relying on very long and cumbersome procedures – sometimes necessary, but still very long – we seize the moment and bring the actors together when rapid decisions are needed. It is of course voluntary, but it nevertheless indicates a very clear direction and brings together the actors who can really make a difference.”
The European Investment Bank Group has accompanied the agreement with concrete financial commitments: a €500 million pilot fund for long-term power purchase agreements (PPAs) for storage, plus a further €1.5 billion programme for grid infrastructure and storage facilities. The aim is to lower the cost of capital for projects that would otherwise struggle to attract private financing.
22 countries join
The agreement has secured the support of 22 out of 27 member states — a higher number than initially expected and a sign of broader political consensus than the divisions within the Energy Council had suggested. The 22 EU countries are Austria, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Malta, the Netherlands, Poland, Portugal, Romania, Slovakia, and Spain.
Analysts see this strong participation as evidence of the dossier’s growing political maturity. After years in which storage was treated as a secondary technical issue, European governments now recognise it as a top-tier strategic priority — especially in a context of persistently high and volatile energy prices.
Voluntary commitments in an immature market
The agreement is not without weaknesses. The most delicate point is the voluntary nature of the commitments: there are no binding verification mechanisms or formal consequences for non-compliance. The Commission deliberately chose this approach to avoid lengthy legislative procedures and to maximise participation. The risk is that pledges remain on paper if market signals do not improve as quickly as declared intentions.
The scale of the targets is another challenge. The 30–35 GW of new capacity represents significant progress, but still covers only part of the overall need projected for 2030. Moving from 55 GW to 200 GW will require an installation pace Europe has never achieved annually, and presupposes far faster removal of regulatory barriers than national administrations have shown so far.
A launchpad for the Energy Union
Behind the storage agreement lies a broader strategy. The second von der Leyen Commission has chosen the tripartite mechanism as one of its preferred tools for managing the energy transition without having to go through slow ordinary legislative procedures every time. The fact that the storage agreement is explicitly the first in a planned series speaks volumes about Brussels’ intentions: the model is designed to be replicated across different sectors.
This approach also reflects a deliberate political choice regarding the traditional Community method. Rather than imposing top-down targets through regulation, the Commission prefers to create conditions for industry, governments, and finance to converge on shared interests and make public commitments that individual parties would not be willing to assume in isolation.
The Commission has already indicated that the same mechanism will be extended to other energy sectors, including biomethane, energy efficiency, nuclear, and data centres. On the regulatory side, network rules to facilitate storage are due to be updated by early 2027. Additional financial instruments – the Innovation Fund and the new Industrial Decarbonisation Bank foreseen under the Savings and Investments Union – can also be mobilised for qualifying projects. Progress will be reviewed annually until 2028, with the Commission ready to propose corrective measures if results fall short of declared objectives.
