It’s not even a ban on mining,” Kellessaid. “It is a two-year moratorium specifically on cryptocurrency mining operations that are housed at fossil fuel-burning power plants.”•Lake Mariner has a contract with NYPA, a State Agency, for 90 MW of power –NYPA is also partnering with Lake Mariner on a unique program to provide the State’s grid with a significant demand energy response capability NY Senate Passes Bitcoin Mining Moratorium​ 19
