Under Utah’s net-metering law, all electric generating investor-owned utilities and cooperative utilities must offer their customers net-metering for renewable energy systems. Municipal utilities are not required to offer net metering under the law. Investor-owned utilities, like Rocky Mountain Power—currently the only such utility—must net meter up to 20 percent of its 2007 peak demand, while cooperatives must net meter up to 0.1 percent of their 2007 peak demand.

Rocky Mountain Power credits customers at retail rate. Electric cooperatives reimburse customers at their avoided cost rate for generating additional electric.

Net excess generation produced by customers is credited forward on a monthly basis for up to 12 months. At that time any overall net excess generation is credited back to the utility without additional compensation to the customer. Credits revert back to the utility on March 31 of each year.

Under the net-metering law, residential customers may net meter systems up to 25 kW in size, and commercial customers may net meter systems up to 2 megawatts in size. Customer-generated electricity may be from solar, wind, small hydropower, co-generation, or fuel cell systems of up to 25 kW in size for residential systems and 2 megawatts for commercial systems.

Some cities or municipalities have also established net-metering rules for their customers; check the program site for details about net metering in individual cities.

Under the state’s interconnection requirements, a disconnect switch is not required for systems under 10 kW and may be required for a net-metered system up to 2 megawatts, depending on how the system is set up.
