As of December 9, 2025, a report by the Electric Reliability Council of Texas (ERCOT) found that data centers are driving a rapid increase in the number and capacity of large load interconnection requests in the ERCOT region. [1] Grid planners in Texas are assessing more than 233 GW of large load interconnection requests, with over 70% originating from data centers. [2] The total capacity exploring grid interconnection near the end of 2025 increased almost 300% over the 2024 year-end total. [3] The Public Utility Commission of Texas (PUCT), which regulates ERCOT, is implementing a new state law, known as SB 6, that requires standardized interconnection rules and improvements to load forecasting. The PUCT published an implementation road map for SB 6 that sets requirements around data center load curtailment alongside standardizing load forecasting.
