Montenegro’s Pljevlja thermal power complex was responsible for generating approximately 442,000 MWh of electricity from June to August, which constituted around 65% of the total output by state utility EPCG during this period. This reliance on coal highlights the country’s ongoing dependence on fossil fuels, despite advancements in renewable energy initiatives.
The facility operated at an average capacity of about 200 MW, yielding roughly 4,800 MWh daily, according to data from EPCG. The total output for these three months was valued at over €51 million.
If Montenegro had opted to purchase the same amount of electricity from Hungary’s HUPX market, it would have incurred costs of approximately €57.4 million, a figure that does not include additional expenses related to cross-border transmission and other import fees. This comparison underscores the economic significance of the Pljevlja plant within Montenegro’s energy framework, especially during times when hydropower generation is low.
While Montenegro possesses considerable hydroelectric capacity, its generation fluctuates significantly based on rainfall and reservoir levels. During dry spells, the nation risks increased reliance on electricity imports unless the Pljevlja plant is operational.
This dependency positions the thermal power station as both a critical asset for energy security and a long-term challenge for energy policy in Montenegro. The coal sector will likely face heightened scrutiny as the country aligns itself with European Union climate regulations and carbon market standards.
Montenegro is moving towards deeper integration with the European electricity market while simultaneously working on wind, solar, and energy storage projects aimed at reducing reliance on coal and imported electricity. EPCG is expanding its renewable energy portfolio, which includes the Gvozd wind complex.
The ongoing construction of the 21-MW Gvozd 2 extension is expected to generate around 63 GWh annually, contrasting sharply with the 442 GWh produced by Pljevlja in just three summer months. This discrepancy illustrates the substantial challenge ahead in replacing coal-fired power generation.
To effectively transition away from coal, Montenegro will need not only additional renewable capacity but also improved energy storage solutions, grid enhancements, and flexible generation capabilities to manage periods of low wind, solar, or hydro output. The economic implications will become increasingly pertinent as carbon pricing escalates.
Although Montenegro is not yet fully integrated into the EU Emissions Trading System, its ongoing accession process and regional reforms indicate that costs associated with carbon-intensive generation will rise over time. The Carbon Border Adjustment Mechanism further enhances the value of low-carbon electricity for companies exporting energy-intensive products to the EU.
This situation creates a strategic dilemma for EPCG. While Pljevlja currently shields the company and national grid from high wholesale prices and hydrological uncertainties, continued dependence on this facility may lead to escalating costs due to tightening carbon pricing and environmental regulations.
EPCG’s analysis reveals that importing equivalent electricity volumes would have cost at least €6 million more, excluding transmission and congestion charges. However, this assessment does not factor in future environmental liabilities linked to coal operations.
The pressing policy issue revolves around timing. Reducing output or closing Pljevlja prematurely could heighten import dependencies and exposure to volatile wholesale prices. Conversely, prolonged operation may lead to increased compliance costs related to environmental standards and carbon emissions.
The summer production figures indicate that Montenegro has yet to establish a framework capable of phasing out coal without a robust replacement strategy in place. For EPCG, future investments in renewable energy must be evaluated not solely by their installed capacity but also by how swiftly they can provide reliable generation, storage solutions, and grid flexibility to compensate for the firm energy currently supplied by Pljevlja.
