Requires investor-owned transmission and distribution utilities to implement new rate designs for recovering post-restructuring stranded costs by October 1, 2025, with rates applicable through June 30, 2028

Allocates stranded costs across customer classes statewide based on each group's pro rata share of total retail kilowatt-hour energy sales, with a 10% cost increase for residential, small, and medium commercial customers offset by an equal reduction for large commercial customers

Establishes specific rate recovery structures: 100% fixed monthly charges for residential and small commercial customers; 50% fixed/50% volumetric for medium commercial; 85% fixed/15% volumetric for intermediate and large commercial; and 100% volumetric for lighting customers

Directs the Public Utilities Commission to establish new 3-year cost allocation and rate design cycles beginning July 1, 2028, with requirements to promote beneficial electrification across all customer classes

Enacted as emergency legislation, effective immediately upon gubernatorial approval on June 20, 2025, to address disproportionate electricity cost impacts on businesses from net energy billing programs
