Net Metering

Solar panels on home

With net metering technology, you can offset all or part of your electricity requirements.

Net metering measures the difference between the electricity you buy from us and the energy you generate using your own solar or wind equipment.

Typical project steps

In order to participate, you will have to meet all applicable codes and standards, obtain a government approved electric inspection and sign a net metering agreement before we install the new meter. The typical steps are outlined below:

  1. Ensure installer is able to conform to IEEE 1547, UL 1741 and other national, state and local jurisdiction rules.
  2. Complete a Net Metering Application/Agreement for your state (see state icons below).
  3. Submit your application and application fee, if required for your state. We will review it and ask any questions within 30 business days.
  4. Receive Confirmation of Receipt from Rocky Mountain Power. Seek necessary permits.
  5. Receive approval via email from Rocky Mountain Power.
  6. Install the project and have it inspected by local authorities.
  7. Submit approved electrical inspection form to Rocky Mountain Power.
  8. Rocky Mountain Power will install a net meter within 10 days of receipt of the approved inspection.
  9. Start generating electricity.

Technical requirements for safety and reliability

Some of the technical requirements for interconnection to the electrical grid are:

  • Effective grounding – Your generation system must be effectively grounded. Most utility distribution systems in North America, including most of our utility distribution lines, are multi-grounded systems. This means there is a separation of your grounding system and our grounding system in the event of faults on either utility or customer generation equipment. Effectively grounded generation sources are required on multi-grounded systems in order to prevent dangerous over voltages during short circuit events, which serves to protect both customer and utility equipment.
  • Protection against islanding – You will be required to provide an “anti-islanding” scheme. Islanding is a condition in which a portion of Rocky Mountain Power’s system can stay energized and operate by itself even when our sources are de-energized. If warranted, you will be required to pay for protection against islanding.
  • Disconnect switch with visible break –Your distributed energy resource facility must include a UL listed AC disconnect switch that provides a visible break, is lockable in the open position, and is located between the production meter and the sub-panel or other connection to the generating facility. Your disconnect switch must be accessible to Rocky Mountain Power personnel at any time of the day. Specific requirements may vary by state and system size.
  • Protection system meets the latest IEEE 1547 standard – For non-net-metered generation, it must also meet Rocky Mountain Power’s Policy 138 (PDF). If your protection, if the system does not meet the necessary standards, you will be responsible for purchasing and installing additional protection equipment.

A full scope of the interconnection requirements for your installation will be sent to you after your interconnection request is received. Please provide your application to Rocky Mountain Power prior to any installation activity to ensure inclusion of the full scope of requirements in your detailed designs.
