General Information
Ankara Natural Gas Combined Cycle Power Plant was constructed in 27 months between September 2001 and December 2003 and started commercial operation on February 05, 2004.
The Plant has two General Electric 9FA++ model gas turbines-generators, two CMI heat recovery steam boilers and one ALSTOM steam turbine-generator. The net nominal output of the Plant is 770 MW at reference site conditions. At full capacity the Plant can deliver about 6.3 billion kWhs of electrical energy annually to the Turkish Electrical Grid. The Plant consumes about 1 billion m³ of natural gas fuel annually.
The cooling water for the Plant is taken from Ankara Brook, 10 km downstream of Ankara Sewage Treatment Plant. Since the Brook's water at the intake location is highly contaminated a water pre-treatment plant is built on the river bank, 2.5 km away from the main plant site. The water abstracted from the Brook is clarified and filtered. The treated water thus obtained is pumped to the main plant as make up for the cooling water largely and a small portion of it as raw water for the demineralization plant that produces "pure water" for the steam cycle.
The sludge removed from the reactors at the pretreatment plant is collected in a storage shed and disposed at a special location. Ankara CCPP is in effect cleaning Ankara Brook by taking some contaminants away from the Brook's water in the dry sludge at the water pre-treatment plant.
