February 2025:

As part of the reconstruction and new construction of the 110 kV switchyard at the Doblar Hydroelectric Power Plant, we signed a contract with the company Kolektor Igin for the supply and execution of all auxiliary power systems within the switchyard. The scope of the auxiliary power system includes:

• AC auxiliary power distribution boards,
• Distributed AC auxiliary power distribution boards,
• 220VDC auxiliary power distribution boards,
• 110VDC auxiliary power distribution boards,
• Rectifier,
• Inverter,
• Battery banks,
• Diesel generator,
• Auxiliary power cable connections.

The works at the site will be carried out in phases, as both Doblar 1 and Doblar 2 HPPs and the 110 kV transmission system will remain in operation. The project is expected to be completed in the first quarter of next year.
