A New Surplus GE Frame 6-FA Combined Cycle power plant, 225 MW, 50 Hz, nat gas, 0 hours, manufactured in 2011.
INTRODUCTION
The powerplant was designed for local site conditions as a base load combined cycle with 225 MW nominal capacity constructed in a 1 st phase and with intention to add an additional 133 MW as a 2 nd phase expansion.
The 1 st phase natural gas-fired plant has its equipment already 95% (by value) constructed. However, it has never been commissioned due to lack of availability of natural gas. Construction stopped in 2017. All installed equipment is still 100% unused and uncommissioned . The power plant remained uncompleted to this day due to inability of the state to provide the site with natural gas.
It is proposed that the plant be sold for dismantling and re-location.

The 225 MW GE Frame 6FA Combined Cycle Turbine Power Plant is a natural gas-fired power plant that uses a combination of gas and steam turbines to generate electricity. It was designed as a base load combined cycle power plant with a nominal capacity of 225 MW, constructed in a first phase, with the intention of adding an additional 133 MW in a second phase expansion.
The main equipment of the first phase construction includes two 77 MWe GE F6FA+e gas turbine generators (Mark VI control), two generators of 95 MVA, a 74 MW GE steam turbine, two dual pressure heat recovery steam generators (HRSG) with deaerators and feed pumps, an air-cooled steam condenser (ACC) by GEA, a water purification/demineralizing plant, an incoming fuel gas conditioning and metering skid, and two gas turbine fuel gas conditioning and metering skids.
The balance of plant (BoP) includes switch yard with step-up transformers MV, HV for grid connection, station transformers, MV, LV switchgear, effluent treatment plant, fin-fan coolers (for lube-oil and alternator cooling), HV, MV and distributed control system and UPS (uninterrupted power supply), fire water and CO2 fire-protection system (Agnice), 500 kW black-start diesel generator, fuel gas conditioning skid, one per gas turbine, compressed air system (Atlas Copco), cooling water system, hot stacks with diverters, main cabling, generator circuit breakers (GCB) ABB, laboratory equipment, steam piping and instrumentation (not fully connected), boiler feed-water pumps, condensate pumps, two HRSG stacks, two hot-stacks (by-pass stacks) with diverters, and one ACC air-cooled condenser and steam ejector vacuum system.
However, the power plant was never commissioned due to lack of availability of natural gas and construction stopped in 2017. All installed equipment remains unused and uncommissioned. It is now proposed to sell the plant for dismantling and re-location.
The efficiency of the GE Frame 6FA Combined Cycle Turbine Power Plant can vary depending on several factors, such as the operating conditions and the specific configuration of the plant. However, generally speaking, combined cycle power plants like the GE Frame 6FA are known for their high efficiency levels.
In a combined cycle power plant, the exhaust gases from the gas turbine are used to produce steam in a heat recovery steam generator (HRSG). The steam is then used to power a steam turbine generator (STG) to produce additional electricity. This allows the plant to extract more energy from the fuel and increase overall efficiency.
According to GE's specifications, the 6FA gas turbine has a simple cycle efficiency of around 40%, while the combined cycle efficiency can reach up to 57%. However, the actual efficiency achieved in operation can vary depending on factors such as site conditions, maintenance practices, and other operational factors.
