Net metering for electricity generation.

(4) Requires an electricity supplier to petition, before July 1, 2025, the IURC for approval of a new or amended net metering tariff that is subject to the following: (A) If the electricity supplier establishes a limit on the aggregate amount of net metering facility nameplate capacity made available for participation by customers under the net metering tariff, that minimum aggregate amount must be at least 5% of the most recent summer peak load of the electricity supplier. (B) Any limit on the aggregate amount of net metering facility nameplate capacity made available for participation by customers is subject to the reservation of: (i) at least 30% (versus 40% under current law) for participation by residential customers; and (ii) not more than 5% (versus 15% under current law) for participation by customers that install a net metering facility that uses organic waste biomass. (5) Provides that before July 1, 2025, the IURC shall make similar amendments to its net metering rules. (6) Provides that a customer that installs a net metering facility on the customer's premises before the net metering tariff of the customer's electricity supplier terminates under the bill's provisions shall continue to be served under the net metering tariff until the customer removes from the customer's premises or replaces the net metering facility. (Current law requires the customer to continue to be served under the net metering tariff until: (A) the customer removes or replaces the net metering facility; or (B) either July 1, 2032, or July 1, 2047, depending on the date of installation; whichever is earlier.) Specifies that any repairs, updates, or upgrades to portions of a net metering facility that do not increase the nameplate capacity of the net metering facility are not considered a replacement of the net metering facility for purposes of these provisions. (7) Makes conforming changes in other provisions of the statute. Adds a noncode provision that: (1) requires an electricity supplier to file, not later than July 1, 2025, a petition with the IURC for approval of a new or amended net metering tariff, as required under the bill; and (2) provides that upon the IURC's approval of the electricity supplier's new or amended net metering tariff: (A) the electricity supplier's excess distributed generation rate and tariff are no longer in effect; and (B) the electricity supplier's new or amended net metering tariff, as approved by the IURC, is in effect and available to the electricity supplier's customers.
