Yes, the Federal Energy Regulatory Commission (FERC) maintains model (also called pro forma or standard) electric interconnection agreements as part of its regulations under the Federal Power Act. These serve as templates that FERC-jurisdictional transmission providers (e.g., utilities owning interstate transmission, RTOs/ISOs like PJM, MISO) must incorporate into their Open Access Transmission Tariffs (OATTs), with limited deviations allowed only if justified.These models primarily apply to generator interconnections (new generation resources connecting to the grid), not directly to large loads like data centers. Interconnection of large loads (e.g., gigawatt-scale data centers) is generally handled at the state level under local utility tariffs, though FERC has jurisdiction over wholesale aspects and is exploring reforms for large loads via recent DOE directives and proceedings.Key FERC Model/Pro Forma Interconnection AgreementsFERC has established standardized agreements through orders over the years (e.g., Order No. 2003 for large generators, Order No. 2006 for small, and major updates in Order No. 2023 and clarifications in 2023-A). The main ones are:

• Large Generator Interconnection Agreement (LGIA) — For generating facilities >20 MW.
  This is the pro forma LGIA (Standard Large Generator Interconnection Agreement), attached as Appendix 6 to the pro forma Large Generator Interconnection Procedures (LGIP). It covers terms for interconnection service, network upgrades, cost allocation, milestones, liability, termination, and more.
  • Current version reflects updates through Order No. 845-A (2019) and subsequent reforms in Order No. 2023 (2023).
  • Available on FERC’s website (e.g., as a PDF with revision history).
• Small Generator Interconnection Agreement (SGIA) — For generating facilities ≤20 MW.
  This is the pro forma SGIA (Standard Small Generator Interconnection Agreement), used under the Small Generator Interconnection Procedures (SGIP). It includes provisions for parallel operation, inspection/testing, cost responsibility, termination, and disconnection.
  • Updated via orders like Order No. 828 (2016).
  • FERC provides the full text as a downloadable PDF.

These pro forma agreements are not one-size-fits-all “model” contracts for every scenario but standardized templates that transmission providers must adopt (or substantially follow) to ensure non-discriminatory, just, and reasonable interconnection processes. Transmission providers file compliance revisions to their tariffs incorporating these, and FERC approves or modifies them. Interconnection customers can negotiate specifics, but core terms remain standardized.Relevance to Large Loads/Data Centers

• FERC’s models focus on generation (e.g., solar, wind, batteries interconnecting as resources).
• For large loads like data centers, no dedicated FERC pro forma interconnection agreement exists yet. Load interconnections are typically state-regulated (e.g., via utility special contracts or tariffs, as in the DTE Saline case under Michigan PSC).
• However, recent developments include:
  • DOE’s October 2025 directive to FERC to initiate rulemaking for accelerating large-load interconnections (e.g., joint load-generation requests, reduced study times).
  • Ongoing discussions in FERC proceedings (e.g., referencing Order No. 2023’s generator reforms as a model for potential load-side changes).
  • No finalized large-load-specific pro forma agreement as of February 2026.

If you’re asking in the context of a data center’s grid connection (e.g., the Saline project), the relevant agreement would likely be a state-level special contract or utility tariff, not a FERC pro forma LGIA/SGIA—unless the data center co-locates generation or involves wholesale market participation triggering FERC jurisdiction.FERC posts the current pro forma documents on its Generator Interconnection page, including PDFs of the LGIA and SGIA. Let me know if you’d like details on specific articles, recent updates, or how these might apply/analogize to large-load scenarios!
