North Macedonia is preparing to turn part of its largest coal and power complex into the site of its largest solar development. The 134 MWdc Bitola 3 photovoltaic plant is more than a renewable-energy project: it is a practical test of whether Southeast Europe can convert ageing coal sites into productive clean-energy assets without abandoning the regions that powered its economies for decades.
State-owned electricity producer Elektrani na Severna Makedonija (ESM) will build Bitola 3 on an exhausted section of the lignite mine serving the Bitola thermal power station. The estimated project cost is €87 million. Financing combines a sovereign-guaranteed loan of up to €37 million from the European Bank for Reconstruction and Development (EBRD) with €50 million from Germany’s KfW Development Bank.
The numbers make Bitola 3 nationally significant. EBRD estimates that the plant will generate about 176 GWh of electricity a year and avoid roughly 131,000 tonnes of carbon-dioxide emissions annually. The bank’s later financing announcement put the avoided-emissions figure at about 134,000 tonnes, reflecting updated assumptions. Either estimate represents a material reduction for a small power system that remains heavily exposed to coal and electricity imports.
The project also illustrates why former mines and thermal-power sites are becoming valuable locations for renewables. They can offer existing grid infrastructure, industrial land, road access and an energy-sector workforce. Reusing disturbed land can reduce conflicts over agricultural or environmentally sensitive sites, while investment around an existing energy complex can soften the economic shock associated with coal’s decline.
That makes Bitola 3 a regional model, but not yet a complete transition strategy. Solar output is concentrated in daylight hours and varies seasonally. North Macedonia will still need flexible generation, storage, stronger interconnections and better demand management if it is to replace dispatchable lignite without increasing its dependence on imports during winter evenings. A solar plant can reuse the mine site; it cannot by itself reproduce all the system services of a thermal station.
The social dimension is equally important. Bitola is a centre of employment and economic activity, and the project is recognised under North Macedonia’s Just Energy Transition Investment Platform. Its success should therefore be measured not only in megawatts and avoided emissions, but also in retraining, local procurement and the creation of durable jobs. Solar construction is labour-intensive for a limited period, while long-term operations employ fewer people than a mine and power plant. Unless workforce planning begins early, the physical transition may advance faster than the social one.
For the wider SEE market, Bitola 3 demonstrates the growing role of development banks in making large renewable projects possible in smaller, higher-risk markets. The blended financing reduces the cost of capital and gives ESM the ability to undertake a project that might be difficult to finance on purely commercial terms. It also shows how public money can be directed toward assets with several benefits: lower emissions, improved energy security and reuse of coal-related infrastructure.
Bitola 3 will not settle North Macedonia’s energy future on its own. It will, however, answer a more immediate question: can a coal region begin to build its next economic identity on the same ground as its previous one? The project’s longer-term value will depend on whether 134 MWdc of new solar capacity is accompanied by the grid investment, flexibility and workforce transition required to turn the former coal complex into a durable new energy hub.
