Best Practices: Net Metering

  1. Offer annualized net metering with monthly carry forward that is reset following a March/April billing cycle.
  2. Provide customers easy access to their own historical annual and monthly electricity consumption data. Click here for an example.
  3. Net metered billing statements should clearly show the net energy consumed from the utility and any credits carried forward from previous billing periods.
  4. Allow meter aggregation for customers who have more than one electric meter. Meter aggregation allows the monthly surplus generated from a solar panel to be applied to a separate service meter owned by the same customer. See page 14 of Puget Sound Energy’s Schedule 150 Tariff for more information about meter aggregation.
  5. Combine the application for interconnection with applications for a production meter and/or net metering. For example, Puget Sound Energy’s “EZ” Application and Agreement streamlines the application for interconnection, net metering, and production metering with a single form.

 How do we rate?

Washington earns a “B” and Oregon earns an “A” in Freeing the Grid’s review of net metering policies nationwide. Both state standards include the following exemplary practices:

  • Customer ownership of renewable energy credits
  • Net metering credits that roll over, month to month for an entire year

Both Oregon and Washington could become even more solar-friendly by strengthening opportunities for net metering:

  • Remove system size limitations to allow customers to meet all on-site energy needs
  • Increase enrollment limit to at least 5% of utility’s peak capacity
