Hawaii Public Utilities Commission: Primary Regulatory Oversight
The Hawaii Public Utilities Commission (PUC) serves as the primary regulatory body for Hawaii's utilities. The PUC regulates electric, telecommunications, gas, and private water and sewage companies.
The Hawaii PUC consists of three commissioners appointed by the Governor with Senate confirmation. Commissioners serve six-year staggered terms. The PUC sets rates, oversees utility operations, and implements Hawaii's ambitious renewable energy goals.
