Romania - 10 october 2025,
Hidropower Services Company Hidroserv SA has been awarded a significant €97.48 million works contract by Romania's top state-owned energy producer, SPEEH Hidroelectrica SA, to renovate the Stejaru Hydropower Plant (HPP) in Neamț County. In order to improve efficiency, dependability, and safety at one of the nation's most vital energy resources, the project, which was formally signed on October 10, 2025, intends to modernise four important hydro units (HA1–HA4) and associated power plant installations.
Overview and Scope of the Contract
The Stejaru Hydroelectric Power Plant, a vital component of Romania's Bistrița Hydropower system, will undergo extensive renovations as part of the awarded contract, which was published under Notice 675050-2025 in the Official Journal of the European Union (OJ S 197/2025). The contractor will upgrade the plant's general installations and finish overhauling the Type I hydro-aggregates (HA1-HA4) over the course of the project, which is expected to take 66 months.
In line with Romania's national energy strategy, the goal is to increase the plant's operational lifespan, maximise turbine efficiency, and guarantee safe, sustainable energy generation. In the long run, the renovation will guarantee safe operations and aid in the amortisation of prior investments.
Entities Involved
One of the biggest producers of hydroelectric power in Southeast Europe, SPEEH Hidroelectrica SA, the contracting authority, is a state-owned company with its headquarters located in Bucharest. Hidropower Services Company Hidroserv SA, the successful bidder, is a medium-sized business with headquarters in Bucharest that specialises in the upkeep, modernisation, and repair of hydropower facilities.
The fact that only one bid was received and considered is noteworthy because it demonstrates Hidroserv's specialised knowledge and established technical partnership with Hidroelectrica.
Technical specifications and award criteria
Under Directive 2014/25/EU, the contract was awarded through an open process based on a combined score of technical quality (60%) and price (40%). Among the essential quality standards were:
-
Weighted average turbine efficiency (at least 93.5%) is guaranteed.
-
The turbine coupling's maximum guaranteed power (at design head 126.5 m and flow rate 23.5 m³/s)
-
Minimum power guaranteed while operating steadily
In order to ensure that the plant operates at contemporary European standards, the technical evaluation placed a strong emphasis on optimising turbine performance to achieve higher power output and efficiency.
Importance and Effect
A significant turning point in Romania's hydropower modernisation programme, the Stejaru HPP renovation aids in the nation's shift to cleaner, more effective energy systems. When finished, the improved facility will greatly increase the output of renewable energy and improve grid stability in the Moldavia region.
The project's effects go beyond the energy industry because it will eventually lower maintenance costs, create local job opportunities, and boost the regional economy.
Concerning the Winning Company
With its main office in Bucharest, Hidroserv SA is a major participant in the hydroelectric services market in Romania. For turbines, generators, and control systems, the company provides turnkey engineering, maintenance, and refurbishment services. Having collaborated with Hidroelectrica for many years, Hidroserv has proven to be a reliable partner in prolonging the hydropower infrastructure's operational lifespan in Romania.
To sum up:
The renovation of the Stejaru HPP demonstrates Romania's dedication to environmentally friendly electricity production and infrastructure modernisation. It is anticipated that the €97.5 million project, led by Hidroserv, will result in quantifiable increases in grid reliability and efficiency nationwide. The modernisation is in line with Romania's overarching goal of safeguarding its energy future by boosting its reliance on renewable energy sources and reviving its historic hydropower assets.
