Romanian hydropower producer Hidroelectrica has signed a refurbishment agreement for the Raul Mare Retezat hydropower plant. The project is described as a large-scale modernization programme intended to restore generation capacity and improve operational performance at the facility. The contract was signed to support changes at one of Romania’s key energy assets.
Contract value and winning consortium
The refurbishment agreement is valued at €188.5 million excluding VAT. The contract was awarded to a consortium led by COBRA Instalaciones y Servicios, working in partnership with Andritz Hydro. Several Romanian subcontractors are also participating in implementation.
Procurement timeline and revised project economics
The procurement process started in September 2025 through Romania’s public procurement system. Bids were submitted by December 2025. The initial estimated value of the project was €193.3 million, with the final contract awarded after the evaluation phase.
Capacity restoration and grid service focus
The Raul Mare Retezat plant was originally designed with an installed capacity of 335 MW. Technical limitations have reduced effective output to around 200 MW for several years. Hidroelectrica said the modernization programme will recover approximately 135 MW of additional usable capacity.
The company stated that the refurbishment is intended to increase electricity generation and also enhance ancillary services provided to the national grid. It added that the work supports strengthening Romania’s overall energy security.
Equipment scope and operational targets
The refurbishment programme includes replacement and modernization of key equipment. Hidroelectrica said the upgrades are aimed at improving efficiency, reliability, and operational flexibility. The company also expects long-term maintenance and operating costs to be reduced.
According to Hidroelectrica, the upgraded systems will allow the plant to operate according to modern technological standards. The company said this will help the facility respond better to evolving electricity market conditions.
