North Macedonia’s coal industry is concentrated around two power and mining complexes that have supported the national electricity system for decades. REK Bitola is the larger and more important facility, while REK Oslomej has played a smaller role near Kičevo. Both were built around domestic lignite resources and state-owned electricity production.
This structure once gave North Macedonia a measure of energy independence. Locally mined lignite could be converted into electricity without relying entirely on imported natural gas or power from neighboring markets. Over time, however, the advantages of domestic coal have weakened. Mines have become more difficult to operate, generating units have aged, environmental costs have increased and coal imports have sometimes been needed to support production.
North Macedonia is now attempting to replace much of this system with renewable generation, stronger networks and energy storage. Coal nevertheless remains connected to electricity security, regional employment and the finances of the state power company. The transition is therefore not simply a question of closing power plants. It requires the replacement of generating capacity and the economic redevelopment of communities built around mining.
REK Bitola Remains the Center of Coal-Fired Electricity
The REK Bitola mining and power complex is located in the Pelagonia region near the city of Bitola and the municipality of Novaci. Its three generating units have a combined installed capacity of approximately 699 megawatts. This makes Bitola the dominant coal-fired power station in North Macedonia and one of the country’s most important electricity assets.
The plant was designed to burn lignite from nearby open-pit mines. Domestic mining reduced transport distances and allowed the power station and fuel supply to operate as a single industrial complex. For many years, this model supplied a substantial share of national electricity.
Lignite has a lower energy content than higher-grade hard coal. Large quantities must therefore be mined and delivered to maintain generation. Fuel quality, moisture and the mixture of coal entering the boilers can influence plant performance. As local deposits become harder or more expensive to exploit, the economics of the entire complex deteriorate.
Bitola’s importance becomes especially visible during periods of high electricity prices or restricted regional supply. Domestic generation can reduce the amount of power that North Macedonia must purchase on external markets. At the same time, unplanned outages at such a large facility can sharply increase import requirements because the country has limited replacement capacity available at short notice.
This creates a difficult policy balance. Keeping Bitola operational supports energy security, but extending the life of aging units requires maintenance, environmental investment and dependable coal supply. Spending heavily on long-term refurbishment could also compete with investment in the generating assets intended to replace coal.
Oslomej Shows What Happens When Local Lignite Runs Out
REK Oslomej, located near Kičevo, has one generating unit with an installed capacity of about 125 megawatts. It was commissioned in 1980 and was originally supplied by lignite from the surrounding mining area.
The depletion of accessible local reserves gradually reduced the plant’s operating role. Oslomej has experienced long periods of limited or intermittent generation, and imported coal has been considered or used as a way to extend operations. This changes the original economic logic of the facility.
A power station built beside a mine benefits from direct access to fuel and lower transport costs. Once it depends on imported coal, the plant becomes exposed to international prices, border logistics, transport availability and fuel-quality differences. A relatively small and aging generating unit may then struggle to compete with electricity imports or newer forms of generation.
Oslomej has also become one of North Macedonia’s most visible energy-transition sites. Sections of the former mining area are being converted for solar power. Existing roads, grid connections and state-owned land make the location attractive for renewable development.
This does not mean that solar generation can reproduce the operating pattern of a lignite plant without additional infrastructure. Solar output changes with daylight and weather, while coal units can theoretically generate whenever fuel and equipment are available. Storage, transmission development, flexible generation and regional electricity trading are therefore important parts of the replacement strategy.
The transformation of Oslomej is significant because it demonstrates how former mining land can remain economically connected to electricity production after coal extraction declines.
Coal Dependence Extends Beyond the Power Stations
The coal industry has shaped employment and local economic activity in the Bitola and Kičevo areas. Mines and power plants support engineers, equipment operators, maintenance workers, transport services, contractors and administrative staff. Local businesses also depend indirectly on wages and procurement connected to the complexes.
Plant retirement can therefore affect an entire regional economy rather than only the employees working inside a generating station. Some workers may transfer into solar construction, grid projects, mine remediation or other ESM activities, but the skills and employment patterns are not identical.
Solar plants generally require large workforces during construction and much smaller permanent teams during operation. Mine rehabilitation creates employment for a period but does not automatically provide a permanent replacement for decades of coal activity. Economic diversification must therefore extend beyond the energy sector.
North Macedonia’s just-transition planning gives particular attention to Pelagonia and the southwest of the country. The intended measures include worker retraining, support for new businesses, environmental restoration and investment in alternative industries. The effectiveness of these programs will determine whether coal-dependent communities experience an orderly transition or a sudden loss of stable employment.
Mine closure also creates physical obligations. Open pits, waste areas and ash deposits must be secured, restored or adapted for new uses. Water management can remain necessary long after extraction ends. These costs form part of the real price of coal retirement even when they do not appear directly in the operating budget of a power station.
The 2030 Coal Objective Depends on Replacement Capacity
North Macedonia has presented 2030 as the central objective for phasing out coal-fired power under its just energy transition program. The government’s updated National Energy and Climate Plan for 2025–2030 also places renewable growth, storage, energy efficiency and gradual coal withdrawal within the same policy framework.
The target is ambitious because Bitola remains an important source of domestic power. Closing coal units before sufficient replacement capacity is available could increase dependence on imported electricity, particularly during winter demand peaks, dry hydropower periods or regional market disruptions.
The practical timetable will depend on several connected developments. New solar and wind projects must be completed, but installed capacity alone is not enough. North Macedonia must also strengthen transmission networks, add storage, manage variable production and improve its connections with neighboring systems.
Electricity demand will influence the schedule as well. Efficiency improvements can reduce the amount of replacement generation required, while industrial expansion or increased electric heating could produce the opposite result.
Policy continuity is another factor. Coal phaseout dates have changed as governments respond to energy crises, prices and security concerns. A formal target becomes credible only when project construction, financing and plant-retirement decisions begin to follow the same timetable.
Former Coal Sites Are Becoming Renewable-Energy Assets
North Macedonia is increasingly using exhausted or disturbed mining land for solar development. This approach limits competition for agricultural land and allows new projects to use some of the infrastructure already connected to major electricity sites.
At Bitola, plans include several solar installations located on former sections of the mining complex. A 134-megawatt solar project has received international financing support and follows earlier Bitola solar developments. The broader Just Energy Transition Investment Platform is intended to mobilize investment for renewable generation and the replacement of aging coal assets.
Oslomej has already established the same basic model. Solar capacity is being developed on land once used for lignite extraction, turning the site from a fuel source into a location for direct electricity generation.
These projects give ESM a possible route from coal-based production toward a more diverse portfolio. The company already controls the sites, understands the electricity system and possesses technical personnel who may be able to support new energy activities.
However, the transition must move faster than the deterioration of existing coal assets. If new projects are delayed while Bitola and Oslomej become less reliable, North Macedonia could face a gap between the decline of domestic coal generation and the arrival of sufficient replacement power.
North Macedonia’s Coal Exit Will Be an Infrastructure Test
North Macedonia has moved beyond discussing whether coal will eventually decline. The central questions now concern timing, replacement capacity and regional economic protection.
Bitola cannot be removed from the electricity system without a credible combination of renewables, storage, grid investment, interconnection and flexible supply. Oslomej shows both the difficulties created by depleted mines and the potential to reuse coal sites for new generation.
The success of the transition will be measured by more than the date of the final coal closure. It will depend on whether North Macedonia can maintain secure electricity supplies, restore mining land and create durable economic activity in Bitola, Kičevo and surrounding communities. Coal’s role is narrowing, but replacing the system built around it remains one of the country’s largest energy projects.
