The Government of Montenegro has approved a significant financing package aimed at modernizing the Perućica Hydropower Plant, the largest hydropower facility in the country. This initiative is part of a broader strategy to enhance energy system flexibility and bolster domestic generation resilience amid an unpredictable energy landscape expected in 2024 and 2025.
Under the new arrangement, Elektroprivreda Crne Gore (EPCG) will receive a €40 million long-term loan from KfW, a German development bank. This funding is designated for the “Perućica Phase III” project, which includes the installation of a new generating unit known as aggregator A8. The loan features a 10.5-year maturity, a five-year grace period, and a floating interest rate set at 2.23 percent margin plus applicable swap rates.
The A8 unit installation is part of a comprehensive rehabilitation program for Perućica, which plays a critical role in Montenegro’s energy generation mix. In addition to the new unit, EPCG is undertaking improvements on hydraulic channels and refurbishing existing units A6 and A7.
This multi-faceted upgrade strategy represents a shift in how Montenegro views its legacy hydropower resources. Rather than merely serving as baseload power sources, these assets are being transformed into flexible balancing infrastructure that can accommodate an increasing share of renewable energy sources.
Officials from the government have characterized the Perućica upgrade as a structural investment rather than just an increase in capacity. The introduction of unit A8 is anticipated to not only boost total electricity output but also to enhance operational flexibility, allowing for quicker ramp-up times and better dispatch coordination.
This enhanced flexibility is vital as Montenegro’s power system integrates more solar and wind energy. Hydropower facilities like Perućica are being redefined as stabilizing entities within the grid, providing essential services such as frequency control and reserve capacity while moving away from reliance on thermal generation.
The project aligns with regional trends in Southeast Europe, where aging hydroelectric facilities are being upgraded to function effectively as quasi-storage assets amidst growing renewable energy penetration.
In conjunction with the financing for the upgrade, the Montenegrin government has approved an additional €30 million credit facility for EPCG intended to refinance short-term liabilities accrued during 2025. These liabilities primarily stemmed from electricity imports necessitated by reduced domestic generation due to outages at the Pljevlja Thermal Power Plant and adverse hydrological conditions.
This refinancing initiative has been structured as a rollover rather than additional borrowing, meaning it does not increase EPCG’s net debt levels but instead extends maturities and enhances liquidity management. This distinction is significant from a credit perspective, marking a transition toward more stable financing aligned with capital investment cycles.
The Phase III project underscores a broader investment philosophy within Montenegro’s energy sector. Instead of pursuing rapid capacity increases through new constructions, policymakers are focusing on incremental upgrades of existing assets, which involve lower capital expenditure and reduced permitting risks.
Hydropower remains integral to Montenegro’s electricity framework, and modernizing these facilities presents one of the quickest ways to increase generation capacity while enhancing system reliability. The addition of unit A8 may seem modest in capacity terms; however, its value lies in its ability to provide flexibility and efficiency improvements while extending the operational lifespan of existing infrastructure.
The development financing from KfW also reflects ongoing alignment with European energy transition frameworks that emphasize environmental standards and operational efficiency.
The timing of this investment is critical as Montenegro’s power system faces increasing volatility due to hydrological variability and aging thermal assets. By enhancing domestic hydropower output and flexibility, the Perućica upgrade aims to lessen dependency on imports during peak demand periods, particularly in winter months when vulnerabilities are heightened.
Moreover, improved balancing capabilities will facilitate the integration of new renewable projects without destabilizing the grid—a crucial factor as Montenegro progresses with its decarbonization initiatives and aligns more closely with EU energy market regulations.
The combination of development-bank financing, asset modernization, and balance-sheet restructuring indicates that EPCG is adopting a more disciplined investment approach focused on long-term system optimization rather than reactive measures.
In a regional context, Montenegro is following trends observed in parts of Central and Eastern Europe by leveraging existing hydro infrastructure as an effective means to support renewable energy expansion instead of relying solely on large-scale new projects.
The advancement of Phase III at Perućica will serve as an important case study for how legacy hydropower facilities can be reconfigured within modern electricity systems driven by flexibility—an increasingly relevant theme throughout Southeast Europe’s energy transition.
