GE has completed testing of its first 60Hz 7H gas turbines, which are now set to be installed at the Inland Empire Energy Center near Riverside, California for the commercial launch of the technology.

The first of two units planned for the 775 MW station is due to arrive next month.

GE will finance and own the station while Calpine units will manage plant construction and market its output under a long-term marketing arrangement with GE. Following an extended period of GE ownership, Calpine expects to purchase the plant and become its sole owner and operator, with GE continuing to provide long-term maintenance.

The two GE 107 H combined-cycle units, which GE says reach more than 60%, thermal efficiency, are expected to enter commercial service by the summer of 2008.
