Bosnia and Herzegovina’s ERS Seeks Partner for Trebinje 3 Solar Project
Bosnia and Herzegovina is taking another significant step toward diversifying its energy portfolio. State-owned power utility Elektroprivreda Republike Srpske (ERS) has officially launched a public call to find a strategic partner for the development of its new solar power project, Trebinje 3. This move signals a clear intent to accelerate the adoption of renewable energy in the region.
The Search for a Strategic Partner for Trebinje 3 Solar Project
In early March 2026, ERS initiated a tender valued at approximately €32 million, seeking a partner to both finance and construct the planned 53.6 MW solar facility. According to reports from regional outlets like Balkan Green Energy News and SeeNews, the tender outlines a collaborative approach. Rather than pursuing a traditional procurement model, ERS is looking for a partner to share the investment and oversee the installation and construction phases of the project.
This partnership model is becoming increasingly common for large-scale energy projects, as it helps mitigate financial risk for the state utility while leveraging the technical expertise and efficiency of private sector developers.
Project Details and Impact of Trebinje 3 Solar Project
The Trebinje 3 solar power plant is a key component of the renewable energy development strategy for the Republika Srpska entity within Bosnia and Herzegovina. The key details of the tender are:
- Project: Trebinje 3 Solar Power Plant
- Capacity: 53.6 MW
- Estimated Value: €32 million
- Objective: To secure a partner for joint financing and construction.
The successful development of Trebinje 3 will contribute significantly to the country’s clean energy goals, reducing its carbon footprint and enhancing its energy security. The project is situated in a region with high solar irradiation potential, making it an economically viable and environmentally sound investment.
A Growing Trend in the Balkans: The Trebinje 3 Solar Project
The announcement from ERS is part of a broader trend across the Balkan region, where governments and state utilities are increasingly turning to solar and wind power to modernize their energy systems. As reported by Serbia SEE Energy News, such tenders are attracting international attention from investors and energy firms looking to expand their footprint in Southeast Europe.
The call for a partner for the Trebinje 3 project represents a prime opportunity for experienced developers in the renewable energy sector. The outcome of this tender will be closely watched as an indicator of the investment climate and the progress of the green transition in Bosnia and Herzegovina.
