Montenegro is preparing an approximately €50 million energy-transition programme for Pljevlja, combining cleaner household heating, district-heating expansion and building-efficiency measures in the coal-dependent municipality. The proposed Montenegro Just Energy Transition project (M-JET) is being developed with support from the World Bank. It would combine investment in a new renewable heat source with expansion of the municipal heating network, household conversion measures and energy-efficiency improvements. The Energy Ministry said the programme remains under preparation and that its final financing structure has not yet been agreed.
Project preparation and financing
Montenegro initially plans to seek $2 million-$2.5 million in grants for feasibility studies, environmental work, technical preparation and financial analysis. The larger investment phase is expected to receive support from the World Bank, while grants through the Western Balkans Investment Framework (WBIF) could potentially finance up to 30% of the project value.
Neither the potential WBIF contribution nor the approximately €50 million overall project envelope has been committed. The initial preparation funding will establish the project’s technical and financial viability. Studies will need to determine the preferred heat source, network route, customer base, construction costs, tariff structure and environmental impact.
Pljevlja’s heating and coal dependence
Pljevlja is home to Montenegro’s only coal-fired power plant and associated lignite mine, making the local economy dependent on activities facing increasingly stringent European climate and emissions requirements. The municipality has also experienced persistent air-quality problems associated with coal combustion, household heating and industrial emissions. M-JET would address part of those issues by changing the way homes and public buildings are heated. A new renewable heat source would form the centre of the proposed system, supported by an expanded district-heating network. The final technology, capacity and detailed construction timetable have not yet been disclosed.
Households outside the district-heating network could receive assistance to replace coal, wood and other higher-emission heating sources with cleaner alternatives. The programme would also finance energy-efficiency measures to reduce the amount of heat buildings require. Such measures are intended to address heat losses through inefficient walls, roofs and windows, while potentially reducing the capacity needed from future heating infrastructure.
Just-transition framework
The programme is being developed as part of Montenegro’s broader just-transition strategy, aimed at reducing the social and economic effects of moving away from coal. Pljevlja has for decades benefited from employment, tax revenues and economic activity associated with the thermal power plant and coal mine. The municipality’s transition therefore involves not only reducing coal-related activity but also addressing the potential economic effects of that change through alternative infrastructure and investment. The European just-transition approach combines decarbonisation with investment in alternative infrastructure, employment and economic activity.
Energy policy and EU alignment
The transition is becoming increasingly relevant as Montenegro advances toward EU membership. Coal-fired generation faces tighter environmental and carbon constraints across Europe, while Montenegro is gradually aligning its energy and environmental policies with EU requirements through the Energy Community framework.
Progress toward closing EU accession Chapter 15 on Energy reinforces this policy direction. The Pljevlja thermal power plant remains strategically important because it provides dependable domestic electricity when hydropower production is weak. An abrupt closure would therefore be economically difficult. At the same time, continued coal generation is expected to face rising costs as emissions requirements tighten and carbon pricing becomes more significant. The proposed heating transition would allow Montenegro to begin reducing direct fossil-fuel combustion in households while the wider electricity-generation transition continues.
Economics of district heating
The financing and design studies will be important because the economics of district heating depend significantly on customer density. Networks are more viable when many customers can be connected within a relatively compact area, while extending pipelines across dispersed neighbourhoods can substantially increase capital requirements. Tariff design will also be important. If district heating costs significantly more than existing household heating options, customers may have limited incentives to connect.
Conversely, artificially low tariffs could leave the system dependent on continuing subsidies. The project therefore needs to balance affordability and financial sustainability. Energy-efficiency investments can support that balance because better-insulated buildings require less heat, potentially reducing both household bills and system operating costs. International financiers increasingly treat heating networks and building renovation as connected investment areas rather than separate sectors.
Infrastructure and investment potential
The proposed financing structure reflects Montenegro’s wider use of blended infrastructure financing, combining sovereign or international financial institution loans with European grants. For a small economy with substantial infrastructure requirements, grant financing can materially improve project economics. If WBIF support eventually reaches 30% of the €50 million programme, the grant element could be significant and reduce the borrowing requirement for the government or participating public utilities.
That remains a potential financing structure rather than an approved allocation. If the project proceeds, its investment programme could include heat-generation equipment, pipelines, substations, building renovation, metering and control systems. It could also generate work for local construction and engineering companies, as well as environmental consultants, designers and project-management providers during preparation and implementation.
Preparation before investment commitments
The immediate priority is the $2 million-$2.5 million preparation package, which is intended to provide the evidence required by potential lenders and grant providers. The distinction between project preparation and execution remains important because the approximate investment scale and possible financing sources have been identified, but capital commitments have not yet been finalised. A successful preparation phase would establish the technical and financial basis for the proposed heating network, renewable heat source, household conversion measures and building-efficiency investments.
