Public consultation opens on Projects of Energy Community Interest 2026 

The projects under consideration have been identified for their potential to deliver clear cross-border benefits, helping the region address infrastructure bottlenecks and adapt its grids to rising renewable energy demand.

The Energy Community has launched a public consultation on projects under consideration for the next list of Projects of Energy Community Interest (PECI). 

Under Regulation (EU) 2022/869 (revised TEN-E), a PECI list must be adopted every two years, with the next list scheduled for December 2026. Of 27 projects submitted, eight electricity projects have now been screened and are open to public consultation. The consultation is open from 16 March to 17 April 2026, and stakeholders are invited to submit comments by email. To do so, follow the link in the sidebar.

1. 400 kV Interconnection Gacko (Bosnia and Herzegovina) – Brezna (Montenegro) 

The project will build a new 400 kV electricity interconnection between the Gacko substation in Bosnia and Herzegovina and the Brezna substation in Montenegro. By strengthening cross-border transmission capacity, it will help integrate new renewable energy in both  Energy Community Contracting Parties, reduce congestion in the regional grid, and improve market integration and security of supply. 

2. Transbalkan Corridor – Double 400 kV OHL Pljevlja (Montenegro) – Bajina Bašta (Serbia) – Višegrad (Bosnia and Herzegovina) 

This project will build a double 400 kV transmission line linking Bajina Bašta in Serbia with Pljevlja in Montenegro and Višegrad in Bosnia and Herzegovina, thus completing the Transbalkan electricity corridor. It will increase cross-border transmission capacity, facilitate larger electricity exchanges with Italy, and support the integration of renewable energy across the regional power system. 

3. 400 kV Interconnection Brezna (Montenegro) – Sarajevo 20 (Bosnia and Herzegovina) 

The project will build a new 400 kV electricity interconnection between Brezna in Montenegro and Sarajevo 20 in Bosnia and Herzegovina, including the construction of a new 400/220 kV Piva’s Mountain substation. It will strengthen cross-border transmission capacity, reduce congestion and losses, support renewable energy integration, and improve security of supply and electricity market integration between the two Contracting Parties. 

4. Rehabilitation of the 220 kV Interconnection Trebinje – Perućica – Podgorica – Vau Dejës 

This project will rehabilitate the existing 220 kV transmission line linking Bosnia and Herzegovina, Montenegro, and Albania by replacing ageing conductors and equipment to increase transmission capacity. The upgrade will relieve congestion between the three Contracting Parties, enable greater integration of renewable energy, and improve cross-border electricity exchange and security of supply in the region. 

5. 400 kV Interconnection Corridor East–West (Kosovo – North Macedonia) 

This project will construct a new 400 kV transmission line between the Prizren substation in Kosovo* and a new substation in Tetovo, North Macedonia, as part of the East–West interconnection corridor. It will strengthen regional grid connectivity with Albania, increase cross-border electricity exchange in the Western Balkans, and support renewable energy integration while improving security and flexibility of supply. 

6. Moglice Extension Pumped-Storage Hydropower Plant (Albania) 

This project will develop a large pumped-storage hydropower facility in Albania by adding an upper reservoir to the existing Moglice reservoir under the Devoll Hydropower Project. With up to 1,620 MW of installed capacity and around 30 GWh of storage, it will provide critical system flexibility and balancing capacity, supporting renewable energy integration and strengthening electricity security across the Western Balkans and neighbouring EU markets. 

7. Reconfiguration of the 400 kV Grid and New Albania–Kosovo* Interconnection 

This project will expand the 400 kV transmission network between Albania and Kosovo* through new substations, upgraded grid infrastructure, and a new 400 kV interconnection between Fierza and the Prizren area. It will relieve congestion on the existing 220 kV line, enable the integration of more than 1 GW of planned wind capacity in northeastern Albania, and strengthen regional electricity exchange, market integration, and security of supply. 

8. 330 kV Interconnection Balti (Moldova) – Dnestrovsk HPP-2 (Ukraine) 

This project will strengthen the electricity interconnection between Moldova and Ukraine through a new 330 kV transmission line linking Balti and the Dnestrovsk hydropower plant. It will increase cross-border transfer capacity, support electricity market development, improve security of supply, and enable greater integration of renewable energy in the region.
