About Us

CUC is a state government corporation. The Commonwealth Utilities Corporation (CUC) operates the electric power, water and wastewater services on the three main islands of the Commonwealth of the Northern Mariana Islands (CNMI) — Saipan, Tinian, and Rota. The CNMI is one of the five U.S. territories (which include Puerto Rico, U.S. Virgin Islands, Guam, and American Samoa). CUC is a semi-autonomous agency of the CNMI government. As a semiautonomous agency, the CUC should have an independent Board of Directors, appointed by the Governor, whose members serve a concurrent four-year term.

Through a transition period between U.S. Trust Territory management and after the ratification of the CNMI Covenant, in 1975, the CNMI enacted legislation creating CUC. Due to a number of delays in actual implementation, the CUC did not take over operations until October 1987, which up to that time operated under the Department of Public Works (DPW). In the Special Representatives Agreement negotiated between the governments of the CNMI and the United States in July 1985, the CNMI government agreed that utility systems would operate on a full cost recovery basis within three years after passage of the enabling legislation. To date, CUC has yet to achieve full cost recovery.

Locales of Responsibility

There are 14 islands within the Commonwealth of the Northern Mariana Islands (CNMI). CUC is responsible for providing power, water and swer services to the three main islands of Saipan, Tinian, and Rota. Presently, Saipan is the only island where CUC provides wastewater treatment services.
