Texas SB 6 (Data Center Grid Law)
Texas SB 6 (2025): Large Load Interconnection and Curtailment in ERCOT (data centers)
Texas · Tex. SB 6 (2025), amending Tex. Util. Code
- Status
- In effect
- Took effect
- June 21, 2025
- Applies to
- Large-load customers (>75 MW) including data centers and crypto miners; transmission providers and utilities
- Enforced by
- Public Utility Commission of Texas; ERCOT
Texas now regulates how very large electricity users such as data centers connect to the ERCOT grid. Loads over 75 MW face a minimum $100,000 transmission study fee and financial commitments, and new large loads must install remote-disconnect capability so ERCOT can curtail them during grid emergencies.
Who is protected: ERCOT ratepayers and grid reliability generally
Legal detail
SB 6 (89th Leg.) amends the Utilities Code to require PUCT interconnection standards for large loads (default 75 MW threshold), mandatory curtailment protocols for post-2025 interconnections during firm load shed, and uniform cost-allocation/transmission screening fees.
