North Macedonia is preparing to transform part of its largest coal and power complex into the site of its largest solar development. The 134 MWdc Bitola 3 photovoltaic plant represents more than a renewable energy project; it is a practical test of whether Southeast Europe can turn ageing coal sites into productive clean-energy assets while supporting the regions that powered their economies for decades.
State-owned electricity producer Elektrani na Severna Makedonija (ESM) will develop Bitola 3 on an exhausted section of the lignite mine supplying the Bitola thermal power station. The project is estimated to cost €87 million, with financing combining a sovereign-guaranteed loan of up to €37 million from the EBRD and €50 million from Germany’s KfW Development Bank.
Bitola 3 is expected to have a significant impact on North Macedonia’s electricity sector. According to the EBRD, the plant will generate approximately 176 GWh of electricity annually and avoid around 131,000 tonnes of CO₂ emissions each year. A later financing announcement put the avoided-emissions figure at approximately 134,000 tonnes, reflecting updated assumptions. Either estimate represents a substantial reduction for a relatively small power system that remains heavily dependent on coal and electricity imports.
The project also highlights the growing value of former mines and thermal power sites for renewable energy development. Such locations can provide existing grid infrastructure, industrial land, road connections and an experienced energy-sector workforce. Reusing already disturbed land can also reduce pressure on agricultural and environmentally sensitive areas, while continued investment around established energy complexes can help cushion the economic impact of the coal phase-out.
This makes Bitola 3 a potentially important regional model, although it is not a complete energy-transition strategy. Solar generation is concentrated during daylight hours and varies seasonally. North Macedonia will therefore still require flexible generation, energy storage, stronger interconnections and improved demand management if it is to replace dispatchable lignite without increasing its dependence on electricity imports during winter evenings. A solar plant can reuse a former mine site, but it cannot independently provide all the system services delivered by a thermal power plant.
The social dimension will be equally important. Bitola is a major centre of employment and economic activity, and the project forms part of North Macedonia’s Just Energy Transition Investment Platform. Its success should therefore be measured not only by installed capacity and emissions reductions, but also by retraining opportunities, local procurement and the creation of sustainable jobs. Solar construction can generate significant employment during the development phase, but long-term operations require far fewer workers than a mine and thermal power plant. Without early workforce planning, the physical transition could move faster than the social transition.
For the wider Southeast European energy market, Bitola 3 demonstrates the growing role of development banks in enabling large renewable projects in smaller and higher-risk markets. Blended financing can reduce the cost of capital and allow state-owned utilities to undertake projects that may otherwise be difficult to finance on purely commercial terms. It also shows how public financing can support assets delivering several benefits at once, including lower emissions, greater energy security and the productive reuse of coal-related infrastructure.
Bitola 3 will not determine North Macedonia’s energy future on its own. It can, however, provide an important answer to a broader question: can a coal region build its next economic identity on the same ground as its previous one? The project’s long-term value will depend on whether the 134 MWdc of new solar capacity is accompanied by the grid investment, flexibility measures and workforce transition needed to transform the former coal complex into a durable new energy hub.
