Note: The Public Service Commission approved Rocky Mountain Power's transition program for customer generators in September 2017. Rocky Mountain Power ceased accepting net metering applications in November 2017. Existing net metering customers can be grandfathered under the previous net metering rules until 12/31/35. Any customer that owns or leases a renewable energy system, or purchases electricity from an independent energy producer operating a renewable energy system that was installed after November 2017 must take service under Schedule 136, the Transition Program. The summary below describes the rules for Schedule 136.  

Eligibility and Availability

Utah law required the state's only investor-owned utility, Rocky Mountain Power (RMP), to conduct a study of the costs and benefits of net metering; and, working with the Public Service Commission (PSC), to determine a just and reasonable charge, credit, or ratemaking structure, including new or existing tariffs, in light of the costs and benefits. In September 2017, the PSC approved Rocky Mountain Power's Transition Program, Schedule 136, which functions as net billing. Schedule 136 is available to customers who generate electricity using solar energy, wind energy, hydropower, hydrogen, biomass, landfill gas, or geothermal energy. The system capacity limit is 25 kilowatts (kW) for residential systems 2 megawatts (MW) for non-residential systems, whether owned by the utility customer or a third party.

Aggregate Capacity Limit

Schedule 136 is available on a first-come, first-served basis up to a cumulative cap of 170 MW for residential and small non-residential customers, and up to a cumulative cap of 70 MW for large non-residential customers. 

Net Excess Generation

Energy usage is netted in 15-minute intervals. Any excess electricity exported during a 15-minute interval will be credited to the customer at a rate established for each standard service tariff: 

  • Schedule 1, 2 & 3: 9.2¢ per kWh
  • Schedule 6: 3.4¢ per kWh
  • Schedule 6A: 6.6¢ per kWh
  • Schedule 6B: 3.4¢ per kWh
  • Schedule 8: 3.5¢ per kWh
  • Schedule 10: 5.6¢ per kWh
  • Schedule 15.1 (Outdoor Lighting): 4.9¢ per kWh
  • Schedule 15.2 (Traffic Signals): 7.8¢ per kWh
  • Schedule 23: 8.2¢ per kWh

Any net excess generation at the end of an annualized billing period will expire with no compensation to the customer. The annualized billing period is a 12-month billing cycle coinciding with the March billing period for most customers.  

Meter Aggregation

If a customer generator has multiple meters at one location or an adjacent location, the meters may be aggregated for billing purposes. The customer must notify the utility of the order in which they want the kWh credits to be applied to the meters. 

REC Ownership

All renewable energy credits associated with the electricity produced by the system remain with the customer, unless otherwise agreed to or designated by the customer.
