New gas turbine power station rated at 405.6 MW was commissioned on the site of Kazanskaya TETs-3. The project was realized under the program of complex modernization of the station. It is the first power unit commissioned in Russia on the base of 9HA.01 gas turbine manufactured by GE. In result total electric output of the station was increased from 384 up to 789.6 MW. The main task of the project is to provide electric power for the wholesale market of Tatarstan and generate steam for the technological needs of Kazanorgsintez PJSC. The project of power plant construction was realized by GE in cooperation with Gama Power Systems Engineering and Contracting. 9HA gas turbine has high operational flexibility thanks to advanced digital control system. It gives the opportunity to start the plant very quickly and switch to the operation with part loads with high efficiency.
