The construction of 513 MW hydroelectric power plant (located in Sinop Province in the Black Sea region of Turkey) was completed on scheduled target in 2012 and became fully operational in December 2012. Boayabt is the largest hydroelectric power plant owned by private sector. The plant has an annual power generation capacity of around 1,350 GWh. With its massive dam storage and high installed capacity, the plant is recognized as one of the few real peak hour power plants in the Turkish electricity system with no royalty payable to General Directorate of State Hydraulic Works for water usage rights.
