Regulators and utilities across the country are adopting new rules aimed at curbing speculative data center power requests, as grid operators face a surge of proposed projects that may never materialize. New mechanisms include large-load tariffs with minimum contract durations, billing demand thresholds, collateral requirements, upfront impact-study payments, exit fees, and specific power ramp-up schedules. Some utilities are also offering incentives to developers who bring their own generation capacity or commit to clean energy targets.
In Texas, grid operator ERCOT paused new data center interconnection requests while it audits a backlog exceeding 474 gigawatts of proposed load. The state's Public Utility Commission has adopted a cluster study framework for projects exceeding 75 megawatts, and a 2025 state law requires large loads to demonstrate site control, share in grid upgrade costs, and accept curtailment during peak demand periods.
Other states are taking their own approaches. Florida has advanced legislation requiring data centers over 50 megawatts to cover the full cost of their grid connections, while Virginia Governor Spanberger signed an executive order focused on data center accountability. In Montana, a utility has proposed exempting smaller loads under 50 megawatts from added regulatory oversight.
The moves come as more than $170 billion in AI-related data center capacity has been blocked, withdrawn, or stalled nationally since January 2024, largely due to community opposition and grid capacity concerns.
