Located in the picturesque Vardar River valley, in the south of North Macedonia, Perun wind farm (30 MW) represents one of the most important renewable energy projects in the country. This project symbolizes North Macedonia’s transition toward a sustainable energy future and contributes to the stability of the power system.
Project overview
The wind farm is located in the Municipality of Bogdanci, in the village of Stojakovo, covering an area of 515,736 m². Construction started in mid-2023, with completion planned by the end of 2024.
Technical characteristics
- Total installed capacity: 30 MW
- Number of turbines: 6
- Turbine type: Siemens Gamesa 5.0 MW
- Substation: New 33/110 kV TS Perun
- Length of the connection transmission line: 4 km
- Number of transmission line towers: 19
- Reconstruction of the 110/35 kV transmission line between SS Gevgelija and SS Bogdanci
Implementation challenges
- Work in extreme weather conditions – temperatures ranged from storms and heavy rain to summer heat exceeding 45°C.
- Coordination of a large number of teams working daily on different segments of the project.
- Construction of a new 33/110 kV substation, requiring precise integration with the existing grid.
- Erection of a 2×110 kV connection transmission line, with specific geological challenges related to tower foundations.
- Integration of the SCADA system to enable full automation and remote monitoring of wind farm operations.
Elnos Group’s role - solution provider approach
As a Solution Provider, Elnos Group was not only a contractor, but delivered a complete project concept prior to detailed design, enabling optimized solutions and higher efficiency across all phases. Our role included:
