Net metering measures the difference between the electricity delivered to the customer and the electricity exported by customers’ distributed energy resource (DER) systems, which include rooftop solar panels. If a customer exports more energy to the grid than what PPL Electric delivers to that customer, the difference is reflected in the customer’s kilowatt-hour (kWh) bank on their bill. This kWh bank can be used to compensate customers monthly through virtual metering aggregation.

 

What is virtual meter aggregation?

Virtual metering aggregation is the aggregation of meter readings and billing for multiple meters for a host and dependent account.

Below is the list of eligibility criteria:

• The host accounts and dependent accounts must be held by the same individual or legal entity (including parent company) receiving retail electric service from the same company.

• The virtual meter aggregation (VMA) shall be limited to meters located on properties owned/leased by the same customer-generator within two (2) miles of the boundaries of the customer-generator’s property. Additionally, the host and dependent sites must be operated by the same customer-generator.

• The virtual meter aggregation shall only be available for properties located within the company’s service territory.

• Both the host account and dependent accounts must use provider of last resort (POLR) to receive the full benefit of virtual metering. If either account uses an alternate supplier, you will not receive credit for transmission/generation portion of your bill.

Virtual Metering Example

Host Account generates 1,200 kWh in excess of usage. This would be evenly divided between the three accounts, 400 kWh for each account. Please note: we can only transfer the total amount of the credit if the satellite accounts used this amount or more. If one of those satellite accounts uses less than this amount, we can only transfer the credit for the amount used for that month and the excess balance would be transferred back to the banked balance on the host account to be used the following month. 

 

Host Account generates 1200 kWh (Up to 400 kWh monetary credit for each account)
Satellite 1 Account uses 500 kWh	400 kWh would be transferred as a monetary credit leaving a 100 kWh balance to be paid
Satellite 2 Account uses 300 kWh	300 kWh would be transferred as a monetary credit
Satellite 3 Account uses 400 kWh	400 kWh would be transferred as a monetary credit
