Who sets GreyStone Power Corporation's rates
GreyStone Power Corporation is a member-owned electric cooperative. A board elected by its members sets its rates. In some states the Georgia Public Service Commission also reviews co-op rates, but most co-op rate changes do not go through a commission rate case, so watch the co-op's own member notices and board meetings.
Commission contact: Georgia Public Service Commission. How we calculate every figure on this page: methodology.
