Who sets Palmetto Electric Coop's rates
Palmetto Electric Coop is a member-owned electric cooperative. A board elected by its members sets its rates. In some states the Public Service Commission of South Carolina 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.
