Public utilities must file a general rate case at least every three years starting July 1, 2029, with utilities that haven't filed since July 1, 2023 required to file by December 31, 2027.

Rate-regulated electric utilities are prohibited from using automatic rate adjustment mechanisms to recover transmission costs; such costs must instead be addressed through general rate cases.

Virtual power plants (collections of customer-owned distributed generation and storage devices under common control) are established as non-public utilities subject to commission approval and oversight within rate-regulated utility service territories.

The commission must promulgate rules for virtual power plant approval, including standards for evaluating participating resources, eligible proposers, and demonstrated customer benefits.

Integrated resource plans must include evaluation of virtual power plants and customer-owned distributed generation as alternatives, with plans filed every five years starting January 1, 2027.
