Rooftop solar installation & interconnecting with the PUD

All rooftop solar installs need to follow PUD guidelines for interconnection and net metering.  This also includes system expansions (adding more solar and/or a battery), replacing a solar system, or just installing a battery (includes bi-directional EV chargers).

To follow the interconnection process, please see the Solar Interconnection application steps below. This process applies to customers working with solar contractors, as well as customers installing their own systems.

If you have any questions, contact the PUD Energy Hotline at 425-783-1700.

Solar Interconnections <100 kW (Net Metering)

Complete these steps prior to beginning construction so your system can be connected to the PUD grid

1. Submit the Interconnection Application and Net Metering Agreement with all required documents. [Learn more about the application workflow process here.]
2. PUD staff will review your application (allow up to 2 weeks for processing). If approved, you will receive an “Approval to Construct” email. An interconnection processing fee of $85 will be charged to your PUD account.
3. After receiving the “Approval to Construct” email, you can begin installation. You must follow PUD requirements (see Section 6, Generation Interconnection, of our Electrical Service Requirements), local codes, and permits. If one is not in place, the PUD will schedule AMI meter installation.
4. Once your project installation is complete and the electrical permit from your local jurisdiction/L&I has been finalized, submit the Notice of Completion to the PUD.
5. The PUD will review your Notice of Completion and give the OK to turn on your solar system by sending the “Permission to Operate” email.

Tip: If you plan on working with a solar installer, PUD suggests getting bids from at least 3 different installers.
