Best Practices: Net Metering
- Offer annualized net metering with monthly carry forward that is reset following a March/April billing cycle.
- Provide customers easy access to their own historical annual and monthly electricity consumption data. Click here for an example.
- Net metered billing statements should clearly show the net energy consumed from the utility and any credits carried forward from previous billing periods.
- 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.
- 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
