Brief project description
-
KOSTT (Kosovo*)
The project consists of the extension of SS Prizreni 2 (actual voltage 220/110 kV) to the new Prizreni-4 at the 400 kV voltage level and the construction of the new 400 kV interconnection between Albania and Kosovo. The Project includes the following actions on the Kosovar side:
- Construction of SS Prizreni 4 (Nashec), 400/110 kV with one 300 MVA autotransformer, which contains two 400 kV line bays, one 400 kV bus-coupler bay, one 400 kV and one 110 kV transformer bay;
- Expansion of the 110 kV busbar system;
- Construction of the switchyard Gjakova, 400 kV with four 400 kV line bays and 400 kV bus coupler bay;
- Construction of the 400 kV single circuit line, 31.5 km SS Gjakova - SS Prizren 4 (Nashec);
- Construction of the single circuit line SS Gjakova - SS Peja 3 with a length of 35.5 km;
- Construction of the second interconnection line 400 kV SS Nashec - SS Fierza with a length of 70 km (45km in Kosovo and 25km in Albania);
Based on the Energy Strategy 2022-2031, the transmission system of Kosovo should support the integration of more than 1.4 GW in the RES capacity, mainly solar and wind power plants. To achieve the objectives of the Energy Strategy and the National Energy and Climate Plan regarding the electricity sector decarbonisation, reinforcement and reconfiguration of the 400 kV network, new 400 kV interconnectors are needed to accommodate the increased level of additional generation sources, thus creating also further electricity exchange opportunities. In this aspect, the current 220 kV interconnection Fierza – Prizren 2 is often subject to congestions and represents a bottleneck in the network. The new project will reduce the loading of 220 kV line Fierza – Prizren 2, enhance the role of the existing 400 kV interconnection Koman – Kosova B, and together with the new 400 kV interconnection enable the grid integration of large amounts of RES capacities in the power system. The same intense integration of new RES is also foreseen in the Albanian power system. Furthermore, the new submarine 400 kV cable between Albania and Italy which is in the OST plans will enable a new 400 kV corridor which will be used for power exchanges between the regions and will give a positive signal on new investments in RES, market integration, and exchange of power regulation/control reserves so much needed for RES successful integration.Main benefits of this project include:
- Enables the support of new generation capacities from RES;
- Improving the reliability of the regional network, the general security of supply and flexibility in the operation of the power system;
- Increasing the value of the Net Transfer Capacity (NTC) between OST and KOSTT, allowing the increase of energy exchange between neighboring countries;
- Increasing commercial exchanges with Albania and other regional countries and the potential to develop a competitive regional energy market, and integration in pan-European electricity market;
- Helping in the gradual decrease of the role of the internal 220 kV network of the country;
- Enables the reconfiguration of the 110 kV network with the aim of optimizing power flows as well as optimizing the operational conditions of the transmission system.

OST (Albania)
On the Albanian side, the project consists of the extension of SS Fierza to 400 kV level and the construction of the new 400 kV interconnection between Albania and Kosova. The Project will include the following actions:
- construction of a new 400/220/110 kV substation near the existing Fierza substation;
- installation of a 400/220kV, 600 MVA phase shift transformer - PST;
- reconfiguration of the 220 kV and 400 kV lines that will be connected to this substation;
- connection to existing interconnections 400 kV Koman – Kosova B and 220 kV Fierza – Prizren2;
- connection to the 110 kV transmission grid in the area;
- construction of the new 400 kV interconnection line between the new 400/220 kV SS Fierza and the new 400 kV SS Prizren4 in Kosova;
There are currently more than 1.3 GW of wind power plant applications in the northeastern region of Albania, and there is a need to accommodate this increased level of additional generation and create further energy exchange opportunities. In this aspect, the current 220 kV interconnection Fierza – Prizren 2 is often subject to congestion and represents a bottleneck element. This project will reduce the loading of 220 kV line Fierza-Prizren 2, enhance the role of the existing 400 kV interconnection Koman-Kosova B and, together with the new 400 kV interconnection with Kosovo, enable the grid integration of large amounts of wind power plant generating capacity.
The main benefits of this project include:
- Improving the reliability of the regional network, the general security of supply and flexibility in the operation of the energy system;
- Increasing the value of the Net Transfer Capacity (NTC) of the Albanian network, allowing the increase of energy exchange between neighbouring countries;
- A better distribution of the electricity produced by HPP Fierze and other HPPS on the Drin river cascade in the 400 kV network;
- Increasing commercial exchanges with Kosova and the potential to develop the regional energy market;
- Improvement of quality indicators and further utilization of the 400 kV interconnection network through redirection of energy flows;
- Helping in the gradual decrease of the role of the internal 220 kV network of the country;
- Supplying the increasing electricity demand of the Prizren area.

Other data Does the project have a significant environmental impact: NO A brief description of the nature of the impact: A full ESIA/EIA study report is predicted to be carried out for this purpose. It will identify all the potential impacts and risks and will recommend appropriate mitigation measures. If the project was included in previous PECI lists, description of the actions taken since inclusion in the list: Detailed design study, Environmental impact assessment, Technical feasibility study, CBA
The major risk/barriers affecting the project implementation: - Economic risks related to the post-Covid economic situation.
- Financial risks: Transmission fee approval below the tariff needed.
- Financial risks: Delay payments on energy-transmitted bills from connected parties.
- Possible social impact from the expropriation process.
- Environmental risks: delay on receiving necessary permissions and environmental impact in the area where the line corridor will pass.
- Implementation risks: delay on possible expropriation process and project costs increase due to the energy crisis as well as high prices on raw material markets, such as steel.
Risk/barriers mitigation measures: - Economic risk severity is low as KOSTT and OST financial incomes are not affected by this situation.
- The cost-reflective (Kosovo) or correct (Albania) tariff methodology to be interpreted and applied by regulatory institution.
- Development of economic and financial analysis, which will include transmission tariff study and risks/sensitivity analyses and possible mitigation measures for it.
- Early intervention on environmental procedures.
- Cautionary measures are taken to avoid protected areas in the way of the line corridor and every possible deforestation is properly refinanced through a dedicated fund.
- Early intervention on expropriation procedures.
Is the investment project already applied for financing? YES (WBIF in 2024) If financial support has been already granted, the amount of support (in real 2022 million EUR): WBIG Operational Board decision still pending (February 2025)
