The 2,410 MW combined cycle power plant was completed in 1999. The plant comprises 5 units of 442 MW and is configured for normal and peak load operation. Each of these units consists in 3 gas turbines connected to the 345 kV high-voltage system via a 3-winding transformer and one steam turbine connected via a separate unit transformer.
