It will cost about $13.7 million to build a power plant and distribution system on the reservation, which borders the U.S.-Canadian border in northern New York. The tribe would also have to pay National Grid a $4.3 million exit fee.
Mohawk leaders say running their own power plant will result in lower delivery rates immediately and protect the tribe from future rate increases while enhancing its sovereignty. About 11,000 residents live on the New York side of the reservation.
The Mohawks are joining at least nine other tribes who operate their own public utilities.
