Texas PUC's New Proposed Regulatory Changes for Large Load Interconnections

2 min readSources: National Law Review

Texas PUC proposes regulatory changes affecting large load interconnections in the state.

Why it matters: These changes require law firms to re-evaluate strategies as they impact client access to incentives and responsibilities in energy project developments.

  • The Texas PUC targets loads of 75 MW or more with Rule 16 TAC §25.194.
  • Proof of site control is required before entering an ERCOT interconnection study.
  • Developers must provide $50,000 per MW in financial security and $100,000 in fees.
  • Legal strategies might need adjustment due to early site control documentation.

The Texas Public Utility Commission (PUC) has introduced proposed regulatory changes specifically impacting the interconnection of large electrical loads, defined as 75 megawatts or greater. These changes are encapsulated in the proposed Rule 16 TAC §25.194 and are aimed at aligning energy project developments with grid reliability goals.

Key requirements under these changes include the need for developers to furnish proof of site control—such as deeds or lease agreements—before participating in an interconnection study by ERCOT, the Electric Reliability Council of Texas. Additionally, developers have to post a financial security of $50,000 per megawatt and pay a non-refundable fee of $100,000.

An analysis by Foley & Lardner LLP, published in the National Law Review, indicates that these requirements could affect legal strategies. By necessitating early site control, the rules might signal that projects progress independently of incentives, which could impact negotiations and strategic planning for securing governmental benefits.

This proposal follows Texas's Senate Bill 6, effective June 2025, intended to align energy development with economic and grid reliability objectives.

By the numbers:

  • $50,000 — Financial security required per megawatt for developers.
  • $100,000 — Non-refundable fee required for participating in interconnection studies.

What's next: The final decision on these rules will be made before the implementation of Senate Bill 6 in June 2025.
