MHPS ANNOUNCES FIRST FIRE AT DOMINION ENERGY’S GREENSVILLE COUNTY POWER STATION

Advanced technology from MHPS delivered on schedule for largest single block power plant in the US

Lake Mary, Florida – (August 23, 2018) Mitsubishi Hitachi Power Systems (MHPS) today announced a successful first fire for the  Dominion Energy Greensville County Power Station located in Emporia, Virginia.  Designed to generate 1,558 MW, the plant operates three M501J gas turbines supplied by Mitsubishi.  The three gas turbines are the cornerstone of the largest and cleanest gas-fired power block ever operated inside the US.

MHPS has enjoyed a productive relationship with Dominion Energy, delivering two previous plants that each won “Project of the Year” awards from Power Engineering magazine.  One of the keys to success with the Greensville project included on-time delivery by MHPS for all three M501J gas turbines.  Each unit completed installation to support the project’s projected in-service date, and all units synchronized flawlessly as they connected to the grid throughout the past 6 weeks, hallmarked by Unit 1A synchronizing to the grid earlier this month.

MHPS Project Manager, Matt Herbst said, “With the 3rd successful first fire in a row at Greensville, MHPS has successfully met key milestones to keep the project on target to meet commercial operation by the end of 2018. Each engine start validated our commitment to Dominion Energy to provide reliable units on time and on budget. MHPS Construction and Commissioning Services performed expertly. Units 1A, 1B and 1C are all on the grid and generating power. This is the second M501J GTCC Power Plant online in North America, with three more plants to follow this year.”

The start-up team now turns their attention towards commissioning and performance testing to deliver full plant output before the end of 2018.  The station maintains low-carbon intensity by using clean-burning natural gas and the best available control technology to reduce emissions.  Beyond its environmental benefits, the plant provides exceptional thermal efficiency.

MHPS leads all OEMs globally in the development and delivery of 60Hz Advanced-Class Gas Turbines rated above 250 MW.  With 158 units ordered since their first delivery in 2001, MHPS is the global fleet leader for Advanced-Class Gas Turbines.  The MHPS process of buying serial number 1 of any new technology and generating 8,000 hours of electricity in their own combined cycle power plant in Takasago, Japan has proven decisive in allowing them to achieve industry-leading reliability.
