Utah has an excellent net metering policy, which has supported the development of a robust and growing solar market. Utah's rooftop solar market has roughly doubled year-over-year for 15 years and Utah now ranks 6th in the country for solar. Net metering rules have been the subject of several Utah Public Service Commission proceedings in recent years, initiated by a request from Rocky Mountain Power in 2014.
Rocky Mountain Power
Rocky Mountain Power is required to offer a net metering policy in accordance with Utah Code Title 54 Chapter 15, "Net Metering of Electricity." Residential customers may net meter solar installations up to 25 kilowatts and non-residential customers may net meter solar isntallations up to 2 megawatts.
Rural Cooperatives and Municipal Utilities
Utah's Net Metering Policy requires Rocky Mountain Power and all Rural Electric Cooperatives to offer net metering. However, Rural Electric Cooperative Boards of Directors are allowed to rule on certain provisions (including the value of excess generation, customer charges, etc.). Utah's Municipal Utilities are not required to offer net metering, but many offer net metering programs. You should inquire with your utility about their policies before making any solar investments.
