The National Electricity Company (NEK) has initiated a tender for the supply and replacement of generators, turbines, and auxiliary systems at the Chaira pump-storage hydropower plant. This decision follows extensive analyses that revealed the current hydro aggregates have been overused, prompting the need for complete replacements with new, high-tech solutions.
Caretaker Minister of Energy Vladimir Malinov emphasized that this upgrade will ensure the long-term sustainable operation of the power plant, enhancing the security and efficiency of the electricity system. Restoring HPP Chaira’s functionality is a top priority for the caretaker government.
Located in southwestern Bulgaria, HPP Chaira is the largest pump-storage hydropower facility in the region and plays a crucial role in maintaining the security and balance of the electricity grid.
The public procurement process encompasses the design, manufacturing, and supply of the new installations, as well as the removal of old equipment, supervision, tuning, testing, and training personnel. The contract, valued at approximately 110 million euros, is expected to be completed within 42 months. The deadline for bid submissions is November 15.
