Natural gas-fired turbine reaches milestone

Mitsubishi Hitachi Power Systems’ natural gas-fired turbine that will be used at a power plant in Oklahoma topped 8,000 hours in service at a power plant in Japan.

The 486.5-MW M501J was the first unit to go into commercial operation at the Himeji No. 2 Power Station, owned by Kansai Electric Power Co. The combined-cycle plant uses six M501J turbines for a total output of 2,919-MW. The first three units began commercial operation to date, while the remaining three will progressively go into service by March 2015. The first unit went into service in August 2013.

Oklahoma’s Grand River Dam Authority (GRDA) in April signed contracts for a 328-MW 501J turbine and a 167-MW steam turbine to replace a coal-fired unit at the Grand River Energy Center in Oklahoma. The new plant is expected to be running by spring 2017.
