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.
Kahuku is a census-designated place (CDP) in the Koʻolauloa District on the island of Oahu, City & County of Honolulu, Hawaii, United States. In Hawaiian, ka huku means "the projection", presumably a reference to Kahuku Point nearby, the northernmost point of land on the island of Oahu. As of the 2000 Census, Kahuku had a total population of 2,097. The ZIP Code for Kahuku is 96731—a fact that became well-known in the mid-1970s when a popular television game show, The Diamond Head Game, was contested on the grounds of Del Webb's Kuilima Hotel (today known as the Turtle Bay Resort), located there. At the end of each show the announcer would say, "If you plan to be in Hawaii, send a self-addressed, stamped envelope to the Diamond Head Game, Kahuku, Oahu 96731. " The Fox TV Series, North Shore, was filmed there recently.
