Serbia’s state-owned power utility EPS said that the Kostolac wind farm is not currently generating electricity because the project has not yet been formally handed over by the contractor, rejecting claims that the outage is related to weather conditions.
According to the company, the facility has not been officially accepted as completed due to outstanding contractual obligations that remain unresolved. EPS stated that the original completion deadline was 30 October 2024, but more than a year later the contractor has still not fulfilled all agreed requirements. Until these conditions are met, the utility will not issue the final takeover certificate.
EPS also confirmed that it is continuing discussions with the contractors and turbine supplier Siemens Gamesa in an effort to resolve the remaining issues. The company emphasized that completing the project is in the interest of all stakeholders, including contractors, equipment suppliers, financial institutions, and project donors such as the European Union and Germany’s development bank KfW.
The 66 MW Kostolac wind farm began trial operations in late November 2025, when it delivered its first electricity to the grid. The project consists of 20 wind turbines installed on former lignite mining land within the Kostolac complex, making it EPS’s first wind energy project and an important step in diversifying its generation mix.
Once fully operational, the wind farm is expected to produce around 187 million kWh annually, enough to supply approximately 30,000 households. The project cost a total of €144 million, financed through a €110 million KfW loan, a €30 million EU grant, and additional funding from EPS itself.
