Meter Aggregation

Can I use leftover kWh in my Net Metering Bank for another account (i.e., meter aggregation)? 

Meter aggregation applies to a solar customer with multiple electric service meters at the same property. Meter aggregation is the billing process of moving excess banked kWh from a solar net metering account to an eligible non-solar account.

EXAMPLE of an ELIGIBLE meter aggregation: A customer with a non-solar house account and a separate account for their detached garage, where the solar is located. Enrolling in meter aggregation will allow for the net excess kWh to be moved to the house account each bill cycle. Without enrolling in meter aggregation, the net excess kWh will remain on the garage account and be subject to the March 31 reset.

EXAMPLE of NOT ELIGIBLE for meter aggregation: A customer with an account for their house and a separate account for their detached garage where BOTH of those accounts have solar.

• The net meter and aggregated meter must be on the same or a contiguous parcel.
• Both services must be in the same customer’s name.
• The aggregated meter cannot be another solar net meter. In other words, Elmhurst Mutual cannot move banked solar kWh to another solar net metering account.

Net metering aggregation is a software billing function; It is not a physical connection of the meters. Therefore, a credit needs to be deposited into the Net Metering Bank on the current billing statement of the solar account before it can then be moved (aggregated) to another eligible account.

Aggregation requests will be reviewed based on WA state net metering law RCW 80.60.
