Requires electric public utilities to develop and apply special rules for certain data centers to protect non-data center customers from increased costs.**

The bill's target population was broadened from 'large load data centers' (facilities whose primary service is digital data processing) to 'large load customers' (any commercial retail electric customer with monthly demand over 100 megawatts). This could include industrial, manufacturing, or other high-demand commercial facilities beyond data centers.

The cost-protection provision in section e was narrowed from protecting against 'new transmission, distribution, capacity, or energy rates' to only 'increased transmission and distribution costs,' removing explicit reference to capacity and energy rate increases.

The definition of the covered entity was rewritten. The old definition required a facility to be primarily engaged in digital data storage/processing with specific infrastructure (servers, network equipment, etc.) and have at least 100 MW demand. The new definition simply requires a commercial retail electric customer that is a centralized facility or facilities with monthly demand of more than 100 MW.

The tariff design requirement was strengthened: instead of merely 'protecting' non-data-center ratepayers from increased costs, the board must now ensure that 'all costs attributable to the electric public utility's large load customers are assigned to the large load customers as determined by the board.'

A new tariff design requirement was added: the tariff must contain protections to ensure other customers are not placed at risk for paying stranded costs associated with the utility serving the large load customer.

The financial guarantee requirement was changed from ensuring customers will 'take at least 85 percent of service they request' to 'pay for at least 85 percent of service they request,' shifting the obligation from consumption to payment.
