Mitsubishi Hitachi signs deal for 501J gas turbine


A deal to build what may be the most efficient combined cycle power plant in the U.S. was finalized last week in Tulsa, Okla.


Executives from Mitsubishi Hitachi Power Systems and officers from the Grand River Dam Authority gathered in Tulsa on March 21 to sign contracts for a 328-MW gas turbine known as the 501J and a 167-MW steam turbine. The 495-MW unit will replace an old coal-fired unit at the Grand River Energy Center near Chouteau, Okla.
