Main Body
On 9 April 2026, the European Commission published its second list of 235 priority cross-border energy projects, classed as Projects of Common Interest and Projects of Mutual Interest, to help complete the Energy Union, improve interconnectivity and support the integration of renewable energy sources, according to a European Commission announcement. The Commission said these projects would receive regulatory support and be eligible for EU financing, framing the package as a core instrument to modernise Europe’s energy networks and strengthen supply security. On the same day, the Commission also issued new rules to enhance energy market integrity and transparency by tightening the authorization and supervision of entities that report energy market data and by improving data reporting to monitor wholesale markets and prevent abuses, as outlined by the European Commission.
Detailing the scope of the infrastructure push, the Commission reported that the list comprised 113 electricity projects, 100 hydrogen projects and 17 CO2 network projects, according to the European Commission. The Commission stated that the projects would benefit from regulatory facilitation and access to EU funding instruments where eligible, and it linked the list directly to the goals of completing the Energy Union and enabling greater penetration of renewables, as set out in the European Commission communication. The complementary market rules were described by the Commission as measures to improve oversight of data reporting entities and to strengthen mechanisms that deter and detect market manipulation, according to the European Commission.
The announcement followed weeks of political scrutiny on energy affordability and security. On 1 April 2026, Members of the European Parliament asked the Commission about swift measures to reduce energy prices, the revision of the Emissions Trading System and steps to build a genuine energy union amid inflationary pressures linked to conflict in the Middle East, in a written question published by the European Parliament. Also on 1 April 2026, MEPs queried how rising gas and electricity costs were affecting the competitiveness of EU industry compared with the United States and Asia, and questioned the effectiveness of current energy and climate policies, according to a written question from the European Parliament. On 9 April 2026, an additional written question asked how cooperation with Azerbaijan could advance EU energy security while mitigating the risks of over reliance on a limited number of suppliers, as recorded by the European Parliament.
Taken together, the updated priority project list and the new transparency rules signalled a dual-track approach that combined investment facilitation with tighter market oversight to support resilience, according to the European Commission and the European Commission. The infrastructure categories highlighted by the Commission, including electricity grids, hydrogen networks and CO2 transport, pointed to an energy system design that aimed to integrate more variable renewables and to enable decarbonisation in hard-to-abate sectors, as described by the European Commission. The policy steps also unfolded amid broader debate on Europe’s long term energy security, as noted in ECFR commentary on safeguarding Europe’s energy future. In parallel, the EU’s wider investment posture, including connectivity initiatives referenced by the European Parliament, provided context for how cross border infrastructure and market governance reforms could underpin supply diversification, grid stability and the clean energy transition across member states and neighbouring partners.
