Montenegro’s state-owned power utility EPCG has submitted an environmental-impact assessment for its planned 37.6 MW Kapino Polje B2 solar power plant near Nikšić, advancing the project through the permitting process. The filing relates to a facility identified as Kapino Polje B2.
Site area and photovoltaic equipment
The proposed solar facility would cover around 45.9 hectares of land previously affected by activities linked to the Slano-Vrtac hydropower system. The design calls for 64,872 photovoltaic modules, each rated at 580 watts. Supporting infrastructure would include internal roads and access arrangements for construction, maintenance and emergency services.
Grid connection via Štedim and Trubjela substations
A preliminary grid design envisages connecting the project through the planned 35/110 kV Štedim substation. Electricity would then be transferred into the high-voltage network through the future 400/220/110 kV Trubjela substation. The arrangement is not final, as transmission system operator CGES will determine definitive connection conditions.
CGES’s final requirements could affect the infrastructure needed to integrate the solar plant into the grid. Planning work began before the latest environmental application. Montenegro issued urban-planning and technical conditions for the development in March 2025, providing a basis for engineering documentation.
Role in EPCG’s generation portfolio diversification
Kapino Polje B2 is part of a wider EPCG strategy to expand domestic solar generation. The strategy also aims to diversify a generation portfolio that remains heavily dependent on hydropower and the Pljevlja thermal plant. Progress through environmental and grid-connection procedures will influence the project’s final construction timetable.
