A bill to amend the Internal Revenue Code of 1986 to clarify the types of energy conservation subsidies provided by public utilities eligible for income exclusion.

Amends the Internal Revenue Code, with respect to the income tax exclusion for energy conservation subsidies, to define "subsidy" to include amounts received by a customer from a public utility to: (1) pay for electricity generated from an energy conservation measure under a net metering or net billing program; or (2) pay for renewable energy credits attributable to an energy conservation measure. Limits the excludable amount of any subsidy for renewable energy credits to $2,000 times the whole number of years worth of renewable energy credits that are sold by the customer.
