Bosnia and Herzegovina’s state-owned power utility Elektroprivreda Republike Srpske (ERS) has launched a new procurement procedure to assess the possible expansion of the Visegrad hydropower plant, focusing on the installation of an additional generating unit. The tender was published through its subsidiary Hidroelektrane na Drini and includes the preparation of a conceptual design and a preliminary feasibility study.
According to the tender documentation, the task is part of a broader effort to modernise the ageing facility by carrying out detailed technical and economic analyses. The aim is to define key performance indicators that will allow ERS to decide whether the project should proceed to the next development stage. The estimated value of the contract is around €460,000 excluding VAT, and bids must be submitted by 20 February 2026.
The assignment is divided into two consecutive phases. The first phase covers the drafting of the main design for the new turbine-generator unit, which must be completed within five months from the contract’s entry into force, followed by a 30-day period for technical coordination and formal approval by the contracting authority.
In the second phase, the selected contractor will prepare a preliminary feasibility study within two months after the approval of the main design documentation. The contract will be awarded to the bidder offering the lowest compliant price that fully satisfies the technical requirements specified in the tender.
Located on the Drina River upstream from the town of Visegrad, HPP Visegrad has been in operation since 1989. The run-of-river plant, built around a gravity concrete dam with a powerhouse on the left bank, has been producing electricity for more than three decades, a long operating history that now underpins ERS’s plans to upgrade and extend the facility’s capacity.
