Montenegro’s Hydro Plant A7 Modernized, Enhancing Energy Reliability

Elektroprivreda Crne Gore AD Nikšić has successfully completed the reconstruction and modernization of unit A7 at the hydroelectric plant HE Perućica, a critical initiative under the project titled “Reconstruction and Modernization of HE Perućica – Phase II.” This redevelopment enhances the reliability, efficiency, and flexibility of Montenegro’s oldest hydroelectric facility, laying the groundwork for long-term, stable operations within the energy system.

The extensive reconstruction of unit A7 included a wide range of upgrades and the replacement of key equipment. This work featured a complete overhaul of the turbine, incorporating new nozzles and servomotors, as well as the installation of advanced pre-turbine ball valves, turbine regulation systems, excitation systems, management systems, electrical protections, and a modern monitoring system. Additionally, the project involved a comprehensive reconstruction of the generator’s 110 kV field, while existing medium-voltage equipment was replaced with new, insulated busbars.

Project Details and Financial Framework

The installation phase was completed by mid-October 2025, and following successful functional and test evaluations, unit A7 was officially commissioned on October 28, 2025. The new unit is integrated into an advanced SCADA system, enabling its participation in primary electricity generation and providing additional system services, such as secondary regulation, to the power grid.

This project has been executed in partnership with the distinguished contractor Voith Hydro Austria, under a financial arrangement with the German Development Bank (KfW). The total investment for Phase II amounts to €33 million.

Bojan Đordan, the acting executive director of EPCG, emphasized the significance of the A7 reconstruction in the modernization process of Montenegro’s oldest hydroelectric plant and the ongoing enhancement of the company’s production capacities.

“This project successfully merges tradition with modern technology. By modernizing unit A7, we have extended its operational lifespan, increased efficiency, and ensured that HE Perućica remains a reliable pillar of Montenegro’s energy system for decades to come,” stated Đordan. He highlighted the dedication of their teams and the collaborative relationship with Voith Hydro, while reaffirming EPCG’s strategic commitment to sustainable development and energy independence for Montenegro.

With the completion of this project, EPCG reinforces its continuity in implementing development plans and investing in domestic hydroelectric capacities. The overarching goal remains to provide a stable, secure, and environmentally friendly supply of electricity for both citizens and the economy of Montenegro.
