Montenegro’s electricity sector is at a pivotal juncture, grappling with significant risks due to its limited asset base and seasonal generation patterns. Unlike larger regional markets, Montenegro’s energy framework is characterized by a reliance on hydropower and a single coal-fired power plant, leading to vulnerabilities in electricity security and pricing stability. The country’s ability to manage these challenges is contingent upon the coordination of its hydrological resources, thermal generation from the Pljevlja power station, and cross-border interconnections amid climate variability and market integration.
The stability of Montenegro’s electricity system has historically depended on its hydropower resources and the Pljevlja coal plant, which provides essential baseload power. However, this reliance on a single thermal unit poses a structural risk. When the Pljevlja plant is offline or constrained, the country faces an abrupt shift towards electricity imports, often at elevated costs. Projections indicate that planned maintenance for ecological reconstruction at Pljevlja could necessitate imports worth approximately €160 million in the affected year, transforming supply security into a fiscal issue.
Climate sensitivity further complicates Montenegro’s energy landscape. The country experiences fluctuations in hydropower generation due to varying weather conditions, which can lead to significant operational stress during periods of low rainfall. Reports have highlighted potential financial losses for Elektroprivreda Crne Gore in 2025 linked to both the shutdown of the Pljevlja plant and adverse hydrological conditions. Current forecasts suggest that Montenegro may produce around 2,900 GWh of electricity in 2025, falling short of projected demand by approximately 343 GWh.
This situation results in what can be termed “binary years” for Montenegro’s energy system. In wet years, the country may achieve a balanced energy state or even export surplus power; conversely, during dry years or outages, it becomes heavily reliant on imports, leading to fiscal implications that are not easily mitigated within a smaller market framework.
Interconnection plays a crucial role in enhancing Montenegro’s energy security. The Italy-Montenegro submarine cable and associated infrastructure improvements provide strategic advantages by integrating Montenegro into a broader regional market. This interconnection enables better access to competitive electricity procurement channels and supports improved integration of renewable energy sources. The capacity of this link is reported at 1,000 MW, which could help mitigate risks associated with domestic generation constraints.
Montenegro’s electricity market has seen progress in organized trading through the Montenegrin Power Exchange (MEPX), although it still exhibits characteristics of partial maturity. As of 2025, there were 29 participants in the day-ahead market, which accounted for about 12% of total electricity traded. However, limited intraday liquidity and incomplete market coupling contribute to heightened balancing costs during periods of supply stress.
Unlike Serbia, Montenegro lacks a substantial domestic gas generation capacity. Its energy balancing strategy relies heavily on hydro resources and imports. Therefore, ensuring competitive access to imported electricity becomes critical for maintaining system reliability. Storage solutions are also vital; even modest storage capabilities can alleviate peak demand pressures and enhance overall balancing performance.
Looking ahead to 2030, Montenegro’s energy trajectory could unfold along three potential pathways: an “Integrated Montenegro,” where enhanced interconnection and market maturity reduce volatility; a “Volatile Montenegro,” characterized by ongoing challenges in market depth leading to increased import costs; or a “Security-first Montenegro,” prioritizing domestic adequacy at potentially higher costs but risking longer-term fiscal pressures.
The unique aspect of Montenegro’s situation lies in its concentrated electricity portfolio dominated by one major thermal unit and hydrological variability. The quality of interconnections significantly influences risk absorption pricing. As such, strategic focus on integration and market depth will be essential for mitigating volatility and ensuring sustainable energy management as climate conditions fluctuate.
