Authorizes the Public Utilities Commission to reduce nonbypassable charges for industrial customers with new separately metered electric loads used for industrial process heat, limiting these charges to no more than 25% of total volumetric charges to encourage electrification of industrial energy use

Establishes state policy that transmission and distribution cost allocation should follow cost causation principles, including consideration of whether load occurs during peak or off-peak periods

Requires the commission by January 1, 2028 to develop recommendations for reforming high-voltage transmission access charges and request the Independent System Operator to reopen its transmission access charge structure proceedings

Applies only to new industrial loads added on or after January 1, 2027 that are metered separately from existing loads and used solely for industrial process heat, including thermal energy storage systems

Targets large electrical corporations with more than 100,000 service connections in California
