Utah Net-Metering Rules

Date Last Updated8/13/2014
Policy TypeNet-Metering Policy
State/FederalUT
Policy Administrator/Contact OfficeUtah State Energy Program
Policy Initiation Date3/15/2002
Policy SummaryUtah's original net-metering rules were enacted in 2002, and subsequently revised in 2009 and 2013. Utah requires the State's only investor-owned utility, Rocky Mountain Power (RMP), and most electric cooperatives to offer net-metering to customers that generate electricity using renewable energy systems (solar energy, wind energy, hydropower, hydrogen, biomass, landfill gas or geothermal energy). RMP allows net-metering of customer-generated electricity from residential systems <25 kW, and nonresidential systems up to 2 MW. The customer-generated electricity may come from CHP or fuel cell system. A kWh credit is issued for monthly net excess generation (NEG) produced by the net-metering facility and credit is applied to the next billing period. For RMP residential and small commercial customers, excess kWh credits are applied at the retail rate. For RMP large commercial and industrial customers with demand charges, NEG is valued at either an avoided-cost-based rate or at an alternative rate based on utillity revenue and sales in FERC From No. 1. Any NEG at the end of a 12-month period, however, is granted to the utility. For co-op customers, NEG is credited at avoided-cost rate. Legislation passed in 2013 now allows utilities to establish one additional annualized billing period before NEG expires. As determined by the Public Service Commission, RMP net-metering customers are not exempt from the minimum bill charge that all customers must pay.

All renewable energy credits associated with the electricity produced by the system remain with the customer. The aggregate capacity limit for all net-metered systems is 20% of 2007 peak demand for Rocky Mountain Power and 0.1 % of utility's 2007 peak demand for co-ops.
