The State of Hawaii Public Utilities Commission was established in 1913. The Commission’s primary duty is to protect the public interest by overseeing and regulating public utilities to ensure that they provide reliable service at just and reasonable rates.

As of fiscal year 2019, the Commission regulates 1,806 entities, which includes all chartered, franchised, certificated, and registered public utility companies that provide electricity, gas, telecommunications, private water and sewage, and motor and water carrier transportation services in the State.  It also oversees the administration of a One Call Center that provides advance warning to excavators of the location of subsurface installations in the area of an excavation in order to protect those installations from damage; and the Public Benefits Fee surcharge which is used to fund and support energy efficiency programs and services implemented by an independent third party administrator on the islands of Oahu, Maui, Molokai, Lanai and Hawaii.
