S.B. No. 6 aims to improve electricity planning and infrastructure costs for large load customers in Texas by introducing new provisions in the Utilities Code. Specifically, it adds Subsections (c-1) and (c-2) to Section 35.004, which require large load customers to contribute to the costs associated with interconnecting to the electric utility's system. The bill sets a demand threshold of 75 megawatts for new or expanded interconnections and mandates that these customers disclose any similar requests for electric service that could impact their interconnection. Additionally, it outlines requirements such as the payment of a flat study fee for initial transmission screening studies and the demonstration of site control for the proposed load location.

The bill also focuses on enhancing the reliability of the electric grid during emergencies by requiring the independent organization certified for the ERCOT power region to develop a reliability service that procures demand reductions from large load customers with a minimum demand of 75 megawatts. It establishes rules for this service, including specific usage periods during extreme weather, a 24-hour notice requirement, and restrictions on participation for those responding to wholesale electricity prices. Furthermore, the Public Utility Commission of Texas is tasked with evaluating the current methodology for charging wholesale transmission costs to ensure it accurately reflects transmission investment costs, with a deadline for rule amendments set for December 31, 2026. The bill will take effect immediately upon a two-thirds vote from both houses or on September 1, 2025, if such a vote is not achieved.
