Electric utility affordability.

Electric utility affordability. Requires an electricity supplier, other than a municipally owned utility, that is under the jurisdiction of the Indiana utility regulatory commission (IURC) to do the following: (1) Beginning with the first monthly billing cycle that begins after June 30, 2026, apply a levelized billing plan (plan) to all active residential customer accounts: (A) for service provided under the electricity supplier's standard residential tariff to a household that is eligible for and has applied for assistance from the state's home energy assistance program; and (B) to which a plan does not already apply. (2) Not later than April 1, 2026, offer each customer a mechanism by which the customer may opt out of a plan at any time without penalty. (3) Not later than July 1, 2026, for any plan offered by the electricity supplier and applied to an active customer account, amend or design the plan so that plan's account reconciliation mechanism is applied at such times during a calendar year to reflect typical seasonal patterns of electricity usage by residential customers, but not more than two times during a calendar year. Prohibits an electricity supplier from referring to or promoting a levelized billing plan as a "budget billing plan" unless the levelized billing plan also provides other specified forms of relief for customers. Authorizes the IURC to adopt rules to implement these provisions. Amends existing law granting the IURC the authority to take certain actions with respect to the rates and services of public utilities during emergency circumstances, as judged by the IURC, to provide instead that the IURC may recommend that the governor declare a disaster emergency or proclaim a state of energy emergency during which the IURC may take such actions. Specifies that the emergency must result from: (1) a national economic depression; (2) an act of war; or (3) a disaster of unprecedented size and destructiveness. Provides that an electric utility, other than a municipally owned utility, may not terminate residential electric service to a customer on any day with respect to which the National Weather Service has forecast, not earlier than 48 hours in advance, a heat index of at least 95 degrees for the location where the customer receives service. Requires an electricity supplier, other than a municipally owned utility, that is under the jurisdiction of the IURC for the approval of rates and charges to report to the office of utility consumer counselor (OUCC) on a quarterly basis certain data concerning residential customer accounts. Requires the OUCC to annually compile and summarize the information contained in the reports and include the summary in the OUCC's annual report to the interim study committee on energy, utilities, and telecommunications. Provides that an investor owned electricity supplier that is under the jurisdiction of the IURC for the approval of rates and charges must petition the IURC for approval of any change in its basic rates and charges through the submission of a three-year multi-year rate plan (MYRP). Beginning in 2026, requires each electricity supplier to file its first petition with the IURC for approval of an MYRP according to a prescribed schedule. Provides that the base rates for the first rate year of an MYRP shall be established by the IURC in the same manner that base rates would be established in a proceeding for a change in basic rates and charges that occurs outside an MYRP. Specifies that in a petition to the IURC for a multi-year plan, an electricity supplier must include certain information in its case in chief. Provides that for each rate year in an electricity supplier's MYRP, the following apply: (1) A customer affordability performance metric and an associated performance incentive mechanism (PIM) that: (A) is based on the electricity supplier's performance in meeting the customer affordability performance metric; and (B) provides financial rewards or penalties to the electricity supplier based on that performance. (2) A service restoration performance metric and an associated PIM that: (A) is based on the electricity supplier's performance in meeting the service restoration performance metric; and (B) provides financial rewards or penalties to the electricity supplier based on that performance. Sets forth the methods by which the IURC must calculate the prescribed performance metrics and determine the associated PIMs. Sets forth specified findings the IURC must make in approving an electricity supplier's MYRP. Provides that at any time before the expiration of an electricity supplier's approved MYRP, the IURC may, upon its own motion, or at the request of the OUCC or the electricity supplier: (1) examine the electricity supplier's rates under the MYRP; (2) conduct periodic reviews with opportunities for public hearings and comments; and (3) adjust the base rates or PIMs under the MYRP. Beginning in 2029, requires the IURC to include in its annual report certain information about: (1) the status of electricity suppliers' MYRP filings and current MYRPs; (2) electricity suppliers' calculated performance metrics for the current rate year; and (3) the impact of all applicable PIMs on customer rates. Requires the IURC to adopt rules to implement these provisions. Requires an electricity supplier, other than a municipally owned utility, that is under the jurisdiction of the IURC to offer, not later than July 1, 2026, a low income customer assistance program (program) that provides financial assistance to low income residential customers for the payment of monthly bills for utility service. Requires an electricity supplier to annually fund its program in an amount equal to: (1) at least 0.2% of the electricity supplier's jurisdictional revenues for residential customers; plus (2) any contributions from governmental agencies or programs or from other third parties. Provides that if a customer who applies for assistance is eligible for assistance under the program, the electricity supplier shall enroll the customer in the program. Provides that an electricity supplier may, but is not required to, petition the IURC for approval to recover eligible program costs. Provides that "eligible program costs" do not include costs recovered by the electricity supplier through contributions that are provided at no cost to the electricity supplier. Beginning in 2027, requires the IURC to include each year in its annual report specified information concerning each electricity supplier's program with respect to the most recently concluded state fiscal year. Requires the IURC to adopt rules to implement these provisions.
