Residential 1,2,39.2

Note: Rate for Schedules 1,2,3 becomes $0.094/kWh if the Utah State Solar Tax Credit (residential) is not extended in the 2018 Utah Legislative Session

Netting Period

As a solar customer, the energy you generate from your panels and the energy you consume in your home or business will be evaluated every 15 minutes.

  • If you use more energy in your home or business in a 15-minute period, you will be charged your regular power rates for that excess energy consumed.
  • If you use less energy in your home or business in a 15-minute period, you will be credited for each kilowatt hour you send back to the grid at the compensation rates in the table above.
Excess Energy Credits

Credits earned from excess, exported energy to the grid can only be applied to offset your power and energy charges- not against your fixed, monthly customer charge.

All excess credits are surrendered each March and donated to the low-income lifeline program.



Grandfathered Net Metering Customers- Original Rate Structure Customers

RMP customers (residential and commercial) that had solar installed or have a completed application submitted by 11/14/2017 will be considered “grandfathered” net metering customers (NEM Customers) and will be given the current 1:1 energy credits for energy they produce and send to the grid.

All NEM Customers will be grandfathered through 12/31/2035. During that time frame, they will:

  • Receive a 1:1 kWh credit for energy produced credited toward what is consumed in their home or business to credit
  • Credits will be netted monthly
  • Remain in their respective rate classes and not have charges applied, including rate changes, new monthly charges and new fees that are not applied to all other customers in the same rate class.

Grandfathering applies to the meter on the home, not the customer. In other words, when you sell your home, the new owner will receive the same treatment as you did.

Important: To be considered a NEM customer you do not have to have your installation completed, simply that a completed interconnection application was filed out by 11/14/2017.
