Vantage Data Centers campus and Fairfield Energy Center (Millersport)

Also called: Vantage Millersport Campus, Vantage OH2, Fairfield Energy Center

Vantage is building a $2.1 billion campus of four data centers on farmland annexed into Millersport. A separate company wants to build a gas power plant of up to 1,300 megawatts next door to run it. Vantage says the campus will use about 5.5 million gallons of water a year. Neighbors worry about air pollution and secrecy.
