The Expediting Generator Interconnection Procedures Act of 2025 directs the Federal Energy Regulatory Commission to initiate a rulemaking within 180 days to overhaul how generation and energy storage projects interconnect to the transmission system. The rulemaking would revise the pro forma Large Generator Interconnection Procedures and, where appropriate, the Large Generator Interconnection Agreement, with a focus on modeling assumptions by resource type, risk-based study approaches, and the identification of cost-effective upgrade options.
It also calls for improved transparency, better queue-management practices, and performance-enhancing measures to ensure upgrades are constructed in a timely and cost-conscious manner once an interconnection agreement is reached. A final rule must be issued within 18 months of enactment, and the bill preserves existing cost-allocation rules under the Federal Power Act.
In short, the bill sets a fast-track rulemaking to modernize interconnection studies, standardize study criteria, and accelerate the delivery of transmission upgrades tied to generation and storage, while keeping current cost-allocation authorities intact.
At a Glance
What It Does
The Commission must initiate a rulemaking within 180 days to streamline interconnection processing and revise LGIP/LGIA. The revisions require resource-specific modeling, risk-based study methods, flexible upgrade options, enhanced transparency, queue-management best practices, and performance-oriented construction for network upgrades after an interconnection agreement.
Who It Affects
Public utilities that own or control transmission facilities, transmission providers, and interconnection customers (developers of generation and energy storage projects). Utilities and grid operators will need to adapt processes and systems to the new modeling, transparency, and queue-management standards.
Why It Matters
By standardizing modeling assumptions and speeding study results, the bill aims to de-risk project timelines, improve cost certainty, and accelerate deployment of renewables and storage essential for a reliable, lower-emission grid.

What This Bill Actually Does
The bill focuses on making it faster and more predictable to connect new electricity generation and energy storage projects to the interstate transmission system. It requires FERC to start a rulemaking within 180 days that would overhaul the process engineers and developers use when seeking interconnection.
The proposed changes include updating the pro forma interconnection procedures and agreements to incorporate resource-type specific modeling, study methods aligned with risk tolerance, and a menu of cost-effective upgrade options. In addition, the rulemaking would push for greater transparency about study assumptions and results, encourage standardized queue practices, and promote the use of advanced computing and automation to speed up the evaluation of interconnection requests.
The goal is to shorten timelines and deliver necessary network upgrades more quickly after a project signs an interconnection agreement. A final rule must be issued within 18 months, and the bill preserves current cost-allocation authorities under the Federal Power Act, so the changes do not shift who pays for upgrades.
The definitions section sets the terms used in the bill, including what counts as an interconnection request, a generation project, an energy storage project, and who is a transmission provider. The package centers on accelerating interconnection studies while ensuring reliability and cost-effectiveness, rather than simply broadening authority.
The result should be a more predictable and efficient path from project development to integration into the grid, benefiting developers, utilities, and ratepayers over time.
The Five Things You Need to Know
The bill requires FERC to initiate rulemaking within 180 days to streamline interconnection procedures.
It directs revisions to the LGIP and LGIA to use resource-type modeling and risk-based study methods.
The rulemaking must identify and require cost-effective solutions to address network reliability needs identified during studies.
Queue management best practices, transparency, and standardized study criteria must be adopted to speed results.
A final rule must be promulgated within 18 months, and existing cost-allocation authorities remain unchanged.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definitions
This section defines key terms the bill uses: the Commission (FERC), energy storage projects, generation projects, interconnection customers and requests, public utilities, transmission facilities, transmission providers, and the transmission system. These definitions align the scope of the rulemaking with interconnection activities that cross state and federal jurisdictions, and they ensure clarity in how rules will apply to both traditional generation and storage devices.
Rulemaking to Expedite Interconnection Procedures
Not later than 180 days after enactment, the Commission must begin a rulemaking to fix inefficiencies in current interconnection processing and to revise the pro forma LGIP and LGIA. The revisions require resource-type modeling assumptions, study approaches aligned with the interconnection customer’s risk tolerance, and the identification of cost-effective upgrade solutions. The rulemaking also mandates better information-sharing with interconnection customers about assumptions and solutions, the adoption of queue-management best practices (including automation and standardized criteria), and the implementation of transparency and performance-enhancing measures to ensure timely and cost-conscious construction of upgrades after an interconnection agreement is executed. A final rule must be issued within 18 months of enactment.
Savings Clause
Nothing in this section alters the allocation of costs of the transmission system under the Commission’s authority to set rates under section 205 of the Federal Power Act. This preserves existing cost-allocation rules while implementing the expedited interconnection procedures.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Interconnection customers (generation and energy storage developers) gain faster, more predictable timelines and clearer understanding of study assumptions and upgrade options.
- Public utilities and transmission providers benefit from standardized processes, reduced ambiguity, and improved transparency that can streamline planning and reduce backlogs.
- Grid operators and financiers gain greater visibility into project timelines and upgrade requirements, improving project bankability and system reliability.
Who Bears the Cost
- Utilities may incur upfront IT and process modernization costs to implement modeling, transparency, and queue-management requirements.
- Transmission providers could face short-term administrative costs to adopt standardized criteria and new information-sharing practices.
- Ratepayers may ultimately bear some costs if accelerated upgrades are funded through rates, though the bill preserves existing cost-allocation authority to determine such impacts.
Key Issues
The Core Tension
Speed vs. reliability and cost certainty: speeding interconnection studies and upgrade construction must not compromise grid reliability or shift costs unfairly.
The Act seeks to balance speed with reliability and cost control. While it accelerates studies and upgrades, it relies on resource-type modeling and risk-based approaches that require accurate input data and careful implementation.
There is a risk that aggressive timelines could compress the evaluation of network reliability needs or lead to underinvestment without strong guardrails. The bill’s emphasis on transparency and standardized criteria aims to mitigate these risks by making study assumptions explicit and by enabling consistent comparison of upgrade options across providers.
