This bill, the Ratepayer and Technological Innovation Protection Act, would require the commission, on or before July 1, 2026, to establish or modify a special electrical corporation tariff or program, or modify an existing tariff or program, for transmission and distribution service to data centers, eligible customers, as defined, that, among other things, avoids nonparticipating customers, such as existing residential, small business, and agricultural ratepayers, bearing cost shifts, such as the costs of interconnecting facilities or loads that fall short of initial projections and ensures electrical grid investments to serve a data center are fully recovered from the data center in the event that the data center ceases operations or uses less electricity than initially projected. The bill would require the commission, on or before January 1, 2030, to require all retail sellers subject to its jurisdiction to serve any data center subject to the tariff or program with electricity from 100% zero-carbon resources in a manner that does not result in resource shuffling and does not increase carbon emissions elsewhere in the western grid. ensures just and reasonable rates for customers of electrical corporations and does not result in cost shifts to customers who do not receive the tariff. The bill would authorize the commission to require an eligible customer to site distributed energy storage systems and backup power systems that better enable the state to meet its emission reduction goals. The bill would authorize the commission to establish minimum requirements for zero-carbon procurement on behalf of retail sellers for eligible customers receiving the tariff.
