Public utilities provide electric, gas, water or telephone service to customers in a specified area. Utilities have a duty to provide safe and adequate service on reasonable terms to anyone who lives within the service area on without discriminating between customers. Because most utilities operate in near monopolistic conditions, they can be heavily regulated by local, state, and federal authorities. Generally, the local and state agencies are called Public Service Commissions (PSC) or Public Utility Commissions (PUC). Municipal Utilities and Rural Electric Cooperatives may be unregulated though.
Exchange is an unincorporated community in Braxton County, West Virginia, United States that has the ZIP code of 26619. It was originally named Millburn by the owner of the mill there. When the post office was established in 1906 the first postmaster, Mrs. Samantha Duffield, suggested the current name because the stores, the mill, and the blacksmith shop changed owners so often.
