810 MW (2 x 405 MW, ISO) combined cycle power plant, 50 Hz, natural gas fuel.
Consists of two 405.5 MW (ISO) combined cycle power modules in a 1x1x1 arrangement.
Each module includes one General Electric GT-9FA.03 gas turbine, one Alstom steam turbine, and a CMI-designed heat recovery boiler system with supplemental firing.
Electricity generated at 15.75 kV and stepped up to 400 kV via Areva step-up transformers.
Commissioned at the end of 2015; placed in preservation mode shortly after due to lack of natural gas.
Actual operating hours: 2,790 and 1,547 hours since new.
Documented efficiency of 56.85% (at site); theoretical efficiency close to 60%.
Supplemental firing allows each module to generate about 14 MW of additional power.
Service and supply contract with GE in place until 2028.
All original design and construction documentation (civil, mechanical, electrical) included.
Plant control room features Yokogawa complete operations systems integration, 170 kV of UPS backup power, and remote monitoring with GE.
Emergency power provided by two 1 MW emergency generators.
Black start capability requires a 15 MW generator (optional).
Preservation And Maintenance
Maintained under the manufacturer’s (GE) preservation program by qualified professionals.
Program includes annual borescope inspections, scheduled rotation of turbines and generators, scheduled maintenance, recirculating heat for steam and gas turbines, generator heat, and nitrogen blankets for all fluid lines and equipment sections requiring preservation.
Long-term service and parts supply agreement with GE available, as well as maintenance and spare parts supply for the steam turbines.
All plant and equipment will get warranties and performance assurances from the OEM.
