GE Power Systems recently introduced the MS7001FB, the newest member of its F technology family of gas turbines. The STAG 107FB will have a combined-cycle thermal efficiency of 57.3 percent, an improvement of more than two percent compared to the current STAG 107FA offering. A 107FB combined-cycle system will produce 280.3 MW of power, an increase of nearly seven percent over the 107FA. Sithe Energies plans to purchase the first nine 7FBs for three merchant power plants in New York and Pennsylvania. The second customer is LG&E Energy Corp., which has purchased six 7FBs for a merchant plant in Texas.
