"Each electric utility shall make available upon request net metering service to any electric consumer that the electric utility serves."
Net metering is a utility electricity use and payment plan that permits customers generating their own power to be compensated monetarily by allowing the customer's meter to actually run backwards if the electricity the customer generates is more than they consume. At the end of the billing period, the customer only pays for their net consumption: the amount of resources consumed, minus the amount of resources generated.
There are numerous listings and descriptions of net metering programs:
