The Government of Montenegro has sanctioned a financing package to support Elektroprivreda Crne Gore (EPCG) in upgrading the Perućica Hydropower Plant, the largest hydropower facility in the country. This decision is part of a broader strategy aimed at enhancing energy system flexibility and domestic generation resilience in light of anticipated fluctuations in the energy market during 2024 and 2025.
EPCG will secure a €40 million long-term loan from KfW to fund the “Perućica Phase III” initiative, which includes the installation of a new generating unit known as aggregator A8. The loan features a 10.5-year maturity with a five-year grace period and carries a floating interest rate set at 2.23 percent margin plus applicable swap rates.
This upgrade is part of a comprehensive multi-year rehabilitation program for the Perućica plant, which plays a crucial role in Montenegro’s energy generation portfolio. Alongside the new unit installation, EPCG is also focused on improving hydraulic channels and modernizing existing units A6 and A7.
The approach to this upgrade indicates a strategic transition in how Montenegro views its legacy hydropower assets, shifting from traditional baseload generation to more versatile balancing infrastructure that can accommodate an increasing share of renewable energy sources.
Officials from the government have characterized the Perućica upgrade as an essential structural investment rather than merely an addition of capacity. The introduction of unit A8 is expected to boost total electricity output while significantly enhancing operational flexibility, allowing for quicker ramping and better dispatch coordination.
This enhanced flexibility is vital as Montenegro’s power grid integrates larger amounts of solar and wind energy. Facilities like Perućica are being redefined as stabilizers within the system, providing essential services such as frequency control and reserve capacity as the grid transitions away from thermal energy reliance.
The project aligns with regional trends in South-East Europe, where older hydroelectric facilities are being upgraded to serve as quasi-storage solutions amid rising renewable energy penetration.
In conjunction with this project financing, the Montenegrin government has also authorized an additional €30 million credit facility for EPCG to refinance short-term liabilities that arose during 2025. These liabilities were largely associated with electricity imports necessitated by reduced domestic production due to outages at the Pljevlja Thermal Power Plant and unfavorable hydrological conditions.
The refinancing arrangement has been structured as a rollover rather than new borrowing, ensuring that EPCG’s net debt exposure remains unchanged while extending maturities and improving liquidity management. This distinction is significant from a credit perspective, indicating a shift from short-term crisis financing towards more stable funding aligned with long-term capital investment needs.
The Phase III project at Perućica reflects a broader investment strategy within Montenegro’s energy sector. Instead of pursuing rapid expansion through new projects, policymakers are focusing on incremental upgrades of existing assets, which tend to have lower capital intensity and reduced permitting risks.
Hydropower continues to be foundational for Montenegro’s electricity system, and modernization efforts represent one of the quickest ways to enhance generation capacity while bolstering system reliability. Although adding unit A8 may seem modest in terms of capacity, its real value lies in improved flexibility, efficiency gains, and extended operational lifespan.
The development financing from institutions like KfW reinforces Montenegro’s alignment with European energy transition initiatives, which typically incorporate requirements for environmental standards and long-term sustainability considerations.
The timing of this investment is significant given recent volatility in Montenegro’s power system due to hydrological variability and aging thermal infrastructure. By enhancing domestic hydropower production and flexibility through the Perućica upgrade, Montenegro aims to decrease its dependence on electricity 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 compromising grid stability, which will be increasingly crucial as Montenegro progresses with its decarbonization goals and aligns more closely with EU energy market structures.
The combination of development-bank financing, asset modernization, and balance-sheet restructuring suggests that EPCG is adopting a more disciplined investment approach that prioritizes long-term optimization over reactive measures.
In a regional context, Montenegro is following trends seen in parts of Central and Eastern Europe by leveraging existing hydro infrastructure as an economical means to advance renewable energy expansion instead of relying solely on large-scale new developments.
The advancement of Phase III at Perućica will serve as an important case study for how legacy hydropower facilities can be effectively integrated into modern electricity systems that prioritize flexibility—a key aspect of the ongoing energy transition across South-East Europe.
