Expediting Generator Interconnection Procedures Act of 2025
Sponsored By: Representative Castor, Kathy [D-FL-14]
Introduced
Summary
Speed up interconnection of new generation and energy storage to the transmission grid. This bill would direct the Federal Energy Regulatory Commission (FERC) to reform interconnection procedures so projects connect faster, more cheaply, and with clearer study rules.
Show full summary
- Interconnection customers (project developers) would get clearer modeling assumptions and study practices that reflect real operating behavior and the customer’s risk tolerance, helping them understand potential costs and timelines.
- Transmission providers would be required to use queue-management best practices, automation, and standardized study criteria, and to share how they picked cost-effective solutions to identified network needs.
- The Federal Energy Regulatory Commission would have to start a rulemaking within 180 days and issue a final rule within 18 months to update the pro forma Large Generator Interconnection Procedures and related agreements.

Bill Overview
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Faster grid connections for new power
FERC would have to start a rulemaking within 180 days of enactment and finish a final rule within 18 months. The rule would push transmission providers to use realistic resource models, study requests to match customer risk, and pick cost-effective reliability fixes. Providers would need to share clear study info, use automation and best practices to cut queue backlogs, and keep network upgrades on time and on budget. This would mainly help power and storage developers by reducing delays and uncertainty.
Clearer definitions for storage and generators
This bill would set clear definitions for who and what is covered in interconnection. It would spell out what counts as an energy storage project (like batteries, pumped hydro, hydrogen, and other tech), a generation project, an interconnection customer, and more. If enacted, these definitions would guide FERC’s rulemaking and related cases right away.
Keeps current grid upgrade cost rules
This bill would state that the rulemaking cannot change how grid upgrade costs are allocated under existing FERC ratemaking rules. It would keep current cost-allocation authority in place for who pays for network upgrades. That offers certainty for utilities and developers, but it could also limit cost changes some projects might want.
