Regulation (EU) 2022/869 (revised TEN-E) requires the adoption of a PECI list every two years, with the next list due in December 2026.
By the 19 January 2026 nomination deadline, 27 projects were submitted (16 electricity and 11 gas), of which eight electricity projects were found eligible and will proceed to further assessment.
Although not required under the TEN-E Regulation, the two evaluation Groups held a public consultation on these pre-eligible projects from 16 March to 17 April 2026. The Secretariat compiled the comments received, which the PECI Groups will consider when preparing the preliminary list of projects for submission to the Ministerial Council for final approval.
An overview of the pre-eligible 2026 PECI projects is provided below.

Expected year of commissioning: 2030 Infrastructure Category: High and extra-high voltage overhead transmission lines Current phase of the project: Detail design study Environmental permit: Yes Project Description: 220kV OHL Trebinje - Perućica - Podgorica - Koplik corresponds to long-term exploitation and the fact that it passes through region with demanding-difficult climatic parameters. Transmission power (720A) has been exceeded through the increase in requirements for the construction of new capacities (from renewable sources, primarily solar, but also hydro potential). Taking into account the requirements for the connection of renewable sources in Montenegro, B&H and Albania, the capacity of the existing conductor of the transmission line in question, as well as its age and operating condition, it is necessary to carry out its reconstruction. The rehabilitation, primarily due to insufficient capacity, would have to include the complete replacement of conductors, OPGW, insulation, suspension and connecting equipment. Since it is not possible to install classic conductors of higher capacity on the existing poles, due to their construction characteristics, this implies the replacement of the existing ones and the installation of conductors of a special construction, which in terms of transmission power correspond to a conductor that can carry 1500 A, and in terms of mechanical characteristics will not increase the load on the poles in relation to to the load for which the columns are designed.
