Early-Stage Progress and Challenges Mark Energy Community’s Priority Infrastructure Projects

Most projects included in the first list of Projects of Energy Community Interest (PECI) remain at an early stage of development, with several challenges likely to affect their implementation timelines, according to an assessment by the Energy Community Regulatory Board.

The Evaluation Report on PECI projects provides a comprehensive overview of progress on initiatives selected in the 2024 PECI list. It covers six priority investments—five in electricity transmission and one in energy storage—identified as critical for strengthening cross-border interconnections, enhancing security of supply, and enabling greater integration of renewable energy across the Energy Community.

The projects under review include:

• Completion of the 400 kV Albanian internal transmission ring;
• Capacity expansion of the existing 220 kV interconnection between Bosnia and Herzegovina and Montenegro (Trebinje–Perućica overhead line);
• The Trans-Balkan Corridor, specifically the 400 kV double overhead line linking Bajina Bašta in Serbia with Višegrad in Bosnia and Herzegovina and Pljevlja in Montenegro (with the latter two sections included in the PECI list);
• Reconfiguration of Albania’s 400 kV grid alongside a new Albania–Kosovo* interconnection;
• The 330 kV overhead line between Balti in Moldova and Dnestrovsk HPP-2 in Ukraine;
• The 225 MW DTEK energy storage project.

To date, only the Bosnia and Herzegovina–Montenegro interconnection has secured direct financing, provided by the European Bank for Reconstruction and Development. Meanwhile, two projects—the Albanian internal ring and the Albania–Kosovo* interconnection—received financial backing in 2025 from the European Commission through the Western Balkans Investment Framework, as highlighted by the Energy Community Secretariat.

The report finds that most projects are still in conceptual, feasibility, or planning phases, with expected implementation timelines extending from 2028 to 2032. Throughout 2025, efforts have largely focused on feasibility assessments, preparatory activities, financing structures, and regulatory alignment, rather than physical construction.

Importantly, the evaluation notes that no systemic delays have been identified when measured against the expected level of project maturity following their designation in the 2024 PECI list.

However, the report underscores several structural challenges that could affect delivery in later stages. These include complex permitting and administrative procedures—particularly for cross-border infrastructure—ongoing financing constraints and rising investment costs, as well as external risks such as geopolitical and security factors, especially in relation to Ukraine.

The assessment emphasizes that early identification and mitigation of such risks will be essential to ensure a smooth transition from planning to construction in the coming years.

The ECRB also stresses the importance of continued regulatory oversight and proactive engagement by national regulatory authorities to maintain project momentum and ensure efficient implementation.

Looking ahead, the Energy Community Secretariat launched a public consultation in March on eight candidate projects for the next PECI list. The updated selection, aligned with the TEN-E Regulation framework, is expected to be adopted in December 2027, following an opinion from the ECRB anticipated by the end of August 2026.
