Customer generation
To help meet our customers' electricity needs, we're committed to using cost-effective renewable energy sources.
We partner with our customers to ensure safe and reliable interconnection of customer-owned private generation systems with the electric grid.
Application process for rooftop solar and other smaller systems
Steps and application
QUOTES: Obtain quotes and choose a reputable installer. Review this checklist.
APPLICATION STATUS: Check the status of your application.
APPLY: Submit an online application with the proposed system, including a picture of the meter.
- Wait for review and confirmation authorizing the interconnection.
- Get permits and install your system, but don’t turn it on yet.
- Have your system inspected, take a picture and let us know. Upload the inspection and a picture of the safety signs, then sign the electronic signature request.
- Give us 7-10 days to install the meter. We’ll let you know when you can turn your system on.
- Generate your own renewable energy!
Typical timeline
Please note: Some projects may take longer than 70 business days depending on the design of your system and/or if any upgrades to our equipment are needed to safely interconnect your system.

Keeping you informed: A meter-mounted device (MMD) is a customer-owned extension of the meter socket installed between the meter socket and the company’s meter and allows for the connection of emergency generation, solar generation, whole-house surge suppression, etc. The MMD form is included in the Customer Generation application and will need to be uploaded to be considered.
Keeping you informed: Effective June 1, 2024, all new inverter-based Customer Generation applications will be required to use UL 1741 SB certified inverters along with provided settings. These inverters will meet the IEEE 1547-2018 standard that updated the specifications and testing for the interconnection of distributed energy resources (DER).
Keeping you informed: To remain eligible for service under Schedule 135 or Schedule 136, a customer may increase the capacity of a grandfathered Eligible Generating Plant by no more than 15% of the originally installed nameplate capacity. This policy is applicable to systems > 10 kW. For systems below 10 kW, customers may increase their system size up to 10 kW.

Keeping you informed: After testimony and public comment since June 2019, the Idaho Public Utilities Commission approved the company’s proposal to close the current net metering program (Schedule 135) to new applicants effective Oct. 2, 2020, and open a new net billing program (Schedule 136) for Idaho customers who choose to generate their own electricity while continuing to rely on Rocky Mountain Power’s network. The change became effective Nov. 1, 2020.
Please take note of these changes before purchasing any equipment. This program and export credit are subject to change, and the export credit will be updated routinely to more accurately reflect the value of the energy exported. The value of the export credit and how often it is updated will be determined by the commission.
