"Net energy" is the difference between the kilowatt-hours consumed by a customer or shared ownership customers and the kilowatt-hours generated by the customer's or shared ownership customers' eligible facility over a billing period.
"Net energy billing" is a billing and metering practice under which a customer or shared ownership customers are billed on the basis of net energy over the billing period taking into account accumulated unused kilowatt-hour credits from the previous billing period.

How does Net Energy Billing Work?
A customer may accumulate unused kilowatt-hour credits and apply
them against kilowatt-hour usage on a rolling 12-month basis. At
the end of each 12-month period, any accumulated unused
kilowatt-hour credits shall be eliminated and may not be applied
against any future kilowatt-hour usage. The customer will receive
no compensation for unused kilowatt-hour credits.
Does Net Energy Billing Apply to Generation?
A customer that has elected net energy billing may obtain
generation service from any competitive electricity provider that
agrees to provide service on a net energy basis. If the customer
obtains service from the standard offer, the standard offer
provider shall provide service on a net energy basis.
How Do I Get Started?
A customer must follow the procedures explained in the MPUC Chapter 324, Small Generator Interconnection Procedures and should become familiar the MPUC's Chapter 313, Net Energy Billing. Please see the Interconnection page.
