The Public Utilities Commission of Ohio (PUCO) is a state regulatory agency established in 1911 that oversees and regulates Ohio’s public utilities, including electric, natural gas, telecommunications, water, and commercial transportation. The commission consists of five commissioners appointed by the governor to five-year terms, with one commissioner serving as chairman. PUCO’s primary responsibilities include setting utility rates, ensuring safe and reliable utility services, monitoring service quality, and protecting consumer interests. The commission regulates more than 1,800 public utilities operating in Ohio and oversees the registration and certification of various transportation companies, including commercial motor carriers, railroad crossings, and hazardous material transporters. The agency conducts investigations, holds public hearings, and makes decisions on utility-related matters such as rate cases, service complaints, and infrastructure improvements. PUCO also implements state and federal regulations concerning utility operations and safety standards. Through its consumer services division, the commission handles customer complaints and provides educational resources about utility services and regulations. PUCO works closely with other state agencies and participates in regional and national utility regulatory organizations. The commission’s decisions can be appealed to the Supreme Court of Ohio, which has exclusive jurisdiction over PUCO cases.
