Byesville, OH: 2023 1.875gw Guernsey County Power Station

(Satellite, it was still a farm field when I accessed it)

The Utica and Marcellus shale beds that I knew were in western Pennsylvania are also in this area (eastern Ohio). These are shale beds that fracking technology made productive. The plant was built next to a gas pipeline and a 765kv power line. [GuernseyPowerStation-facts]

Guernsey Power Station now [Feb 2023] up and running in Ohio.
Paul Dildine: They are single shaft 7HA.02, the GT, generator, and steam turbine on the same line shaft. The steam turbine has a 'triple s' clutch so the GT can be run in simple cycle until steam quality is good. This is the same arrangement as Lackawanna energy center and moxie freedom. The former ops manager from Lackawanna is plant manager at Guernsey.
Erich Amberger: Drew Bednarczyk They are 7HA.02 @ 384mw X 3. And it says the plant is 1875 mw. Looks like it says “ STG FOR EACH 7HA.02” so that would be 241 mw STG X 3. But if you look at GE site 1X1 is only 573 each🤷‍♂️

That is an impressive array of coolers. Looking at a satellite map, there is no large lake or river nearby.

The project was projected to cost $1.6b, and it will employ about 30 people with more people during the spring and fall outages to prepare for the next season. "The plant will be the largest natural-gas powered facility in the United States that was built in a single phase, designed to last 30 years."
"Early stages of the construction phase included six months of site preparation work to include approximately 200,000 cubic yards of grouting in mines abandoned in the 1920s. Approximately 10 to 12% of the project budget involved site preparation."
"One megawatt will power 800 modern homes and the plant can supply up to 300 megawatts to the grid in 10 minutes with the push of a button."
[This is a nice article. They briefly explain how a combined-cycle power plant works.]
"The plant will use 160,000 MMBTU (1 million British thermal units) or 1,000 MCF (volume of 1,000 cubic feet) a day."

"The Guernsey Power Plan was able to bring all of the big equipment in on rail lines reducing the impact on local roadways." [daily-jeff] A satellite image shows that tracks go right past the west side of the site. But, the 2005 SPV Map shows that PennCentral abandoned this Pennsylvania route south of Byesville. I wonder how much work was needed to restore the tracks to the plant.

GE's 7HA.02 gas turbines are "the world’s largest and most-efficient heavy-duty gas turbines....The HA turbine has been recognized for powering the world’s most efficient power plants in both the 50hz and 60hz energy segments. GE’s fleet of HA gas turbines has surpassed more than 388,000 operating hours and secured more than 95 orders from 40+ customers in 18+ countries." [GE-press]

"Using state-of-the-art combined cycle technology and a dry (air) cooling system, the 1,875 MW, Guernsey Power Station, will be a cost and fuel-efficient plant. Each power train, in its own turbine building, will consist of one GE 7HA.02 gas turbine equipped with evaporative inlet cooling, one triple pressure reheat steam turbine and one water/hydrogen cooled electric generator arranged on a common single shaft. Each power train will have an outdoor heat recovery steam generator (HRSG) equipped with supplemental duct firing capabilities, selective catalytic reduction technology for NOx, and an oxidation catalyst for CO/VOC reduction." [GemmaPower]

"The Guernsey power station will receive natural gas supply from the Utica and Marcellus shale gas formations in eastern Ohio and western Pennsylvania, through the near-by Rockies Express (REX)-East pipeline. REX-East is a 1,028km-long and 42in-diameter high-pressure natural gas pipeline that originates from the Clarington natural gas hub in Monroe County of Ohio and runs through Ohio, Indiana, and Illinois to Missouri."
