Trans-European Networks for Energy (TEN-E)

The Trans-European Networks for Energy (TEN-E)¹ policy is the EU’s instrument for connecting EU MS’s energy networks and supporting the development of intra-regional energy infrastructure necessary to support the functioning of the internal energy market, security of supply, and the achievement of the EU’s climate and energy objectives.

The TEN-E Regulation, revised in 2022, aligns EU energy infrastructure planning with the objectives of the European Green Deal, Fit for 55, and REPowerEU. The revised framework shifts focus away from fossil fuel infrastructure and prioritises investments in electricity grids, offshore renewable energy, hydrogen networks, smart grids, energy storage, and carbon dioxide transport, ensuring alignment with the EU’s long-term climate-neutrality goal.

Under the Regulation, stakeholders cooperate within regional groups to identify and implement Projects of Common and Mutual Interest (PCIs and PMIs)² in priority corridors and thematic areas. The revision introduced updated infrastructure categories and reconfigured priority corridors to reflect evolving energy system needs. While PCIs are reserved for EU Member States, PMIs enable intraregional energy infrastructure cooperation between the EU and third jurisdictions, including the Western Balkans 6.
