The bill directs the Secretary of Energy to publish guidelines and best practices for integrated resource planning (IRP) of the electricity system and to provide technical assistance for their implementation. It also establishes an Integrated Resource Planning Modernization Grants Program to help states align their IRP processes with the new guidelines.
The goal is to improve how utilities plan for capacity, reliability, and cost by incorporating new modeling techniques, technologies, and cross-border planning.
At a Glance
What It Does
The Secretary develops IRP guidelines and best practices in consultation with state agencies and industry stakeholders, covering modeling approaches, technology options, interregional planning, data sharing, and metrics. The government also provides technical assistance to help implement these guidelines and, within two years of enactment, to publish them publicly.
Who It Affects
State public utility commissions, state energy offices, investor-owned utilities, municipal utilities, electric cooperatives, balancing area authorities, Transmission Organizations, and other IRP participants across regulated and partially deregulated markets.
Why It Matters
Standardized, comprehensive IRP guidance aims to improve resource adequacy analyses, incorporate storage, DERs, and grid-enhancing technologies, and foster cross-state cooperation, potentially improving reliability and informing regulatory and procurement decisions.

What This Bill Actually Does
The Integrated Resource Planning Modernization Act directs the Department of Energy to build a formal, public set of guidelines and best practices for how the electricity system should be planned over time. In developing these guidelines, the Secretary must consult with state public utility commissions, state energy offices, and a broad set of stakeholders, including various types of electric utilities, balancing authorities, Transmission Organizations, and, importantly, other relevant actors.
The guidelines are tasked with addressing a broad menu of issues, notably capacity expansion modeling, resource adequacy analysis, and the integration of a wide range of generation and demand-side options. This includes traditional generation plus grid-enhancing technologies, storage at multiple scales, behind-the-meter interventions, and demand-side measures.
It also requires planners to consider interregional resource sharing, the role of gas networks, scenario analysis, and probabilistic methods to manage uncertainty, weather variability, fuel prices, and extreme events. The guidelines should also provide a framework for public engagement and the link between planning outcomes and regulatory actions, such as procurement or rate cases.
Within two years of enactment, the Secretary must publish these guidelines on a public DOE website, and they must be evaluated and revised at least every five years to stay current with technology and market changes. The Act also authorizes a Technical Assistance program to help states understand and apply the guidelines through training and workshops.
Separately, a new Integrated Resource Planning Modernization Grants Program would offer grants to states to implement modernized IRP requirements, with different uses and expectations for vertically integrated and restructured states, including funding for consultants, software, modeling, and stakeholder engagement. States would need to submit implementation plans and progress reports, and grants would be subject to a defined formula that considers existing state structure, coverage, consumer base, and infrastructure.
The bill calls for coordination with other federal resilience and modernization efforts and requires periodic congressional reporting on grant use and effectiveness. Finally, the Act defines key terms (such as resource adequacy, capacity value, and grid-enhancing technologies) to ensure consistent understanding across implementation efforts.
The Five Things You Need to Know
The Secretary must publish guidelines and best practices for integrated resource planning within two years of enactment.
Guidelines must address capacity expansion modeling, resource adequacy, storage, DERs, behind-the-meter interventions, and grid-enhancing technologies.
A grants program will fund state implementation of modernized IRP requirements, with formulas considering state structure and size of electricity consumer base.
Grants may be used for consultants, software, modeling, and stakeholder engagement, and must be expended within five years.
DOE will periodically report to Congress on grant use, effectiveness, and best practices, with evaluations every five years.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short Title
This Act may be cited as the Integrated Resource Planning Modernization Act.
Development of Guidelines and Best Practices for IRP
The Secretary will develop comprehensive guidelines and best practices for electric utility integrated resource planning in consultation with state commissions, state energy offices, various classes of electric utilities, balancing authorities, Transmission Organizations, and other stakeholders. The guidelines will cover key issues such as capacity expansion modeling, resource adequacy analysis, interregional planning, the integration of gas and other fuels, demand-side interventions, and new grid technologies, using both traditional and probabilistic methods to address uncertainty and extreme weather.
Publication and Review of Guidelines
Not later than two years after enactment, the Secretary must publish the guidelines and best practices on a publicly accessible DOE website. The guidelines will be periodically evaluated and revised at least every five years to reflect evolving technology, market structures, and planning methods.
Integrated Resource Planning Modernization Grants Program Establishment
The Secretary shall establish a grants program to assist States in modernizing their IRP processes to align with the new guidelines and best practices. The program will fund state implementation plans, support for utilities, and stakeholder engagement, with separate provisions for vertically integrated and restructured states.
State Implementation Plans
States may apply for grants by outlining how they will implement modernized IRP requirements, statutes, and regulations, and how they will coordinate with utilities and other planning entities to develop and apply IRP processes consistent with the guidelines.
Use of Grants in Vertically Integrated States
In vertically integrated states, grants may fund updating IRP requirements, supporting regulated utilities in compliance, and enabling participation by non-regulated utilities that opt in. Grants may also cover consultant services, staffing, software and modeling, and stakeholder engagement necessary to update IRP regulations, as well as reimbursements to utilities for compliance costs.
Use of Grants in Restructured States
In restructed states, grants should coordinate with utilities and planning entities to implement IRP in a manner consistent with the guidelines; grants may cover planning activities, model development, and costs incurred by Transmission Organizations and planning entities in support of implementing the strategy.
First Applications
States may begin applying for grants not later than six months after the initial publication of the guidelines and best practices.
Grant Use Deadline
States that receive grants must use the funds within five years of the grant date.
Grant Formula
The Secretary will determine grant amounts based on existing state requirements, plan comprehensiveness, number of electricity consumers, infrastructure and capacity, distribution of utilities and planning bodies, and other factors the Secretary deems appropriate.
Coordination with Other Federal Programs
The Secretary may coordinate with related federal energy resilience and modernization programs to maximize impact, avoid duplication, and ensure alignment with broader federal initiatives.
Periodic Reports
Not later than five years after enactment and every five years thereafter, the Secretary must report to Congress on grant usage, state progress in adopting modernized IRP, and examples of best practices and innovative approaches.
Definitions
This section provides definitions for key terms used in the Act, including resource adequacy, capacity value, grid-enhancing technologies, distributed energy resources, balancing area authorities, Transmission Organizations, and vertically integrated or restructured states, to ensure consistent interpretation.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State public utility commissions gain structured guidance, data inputs, and modeling outputs to inform regulatory actions and oversight.
- State energy offices receive clear processes and funding pathways to implement modern IRP practices.
- Vertically integrated utilities, municipal utilities, and electric cooperatives that participate in modernized IRP frameworks benefit from consistent standards and potential regulatory relief in implementing new planning methods.
- Balancing Area Authorities and Transmission Organizations gain a standardized planning horizon and validated capacity metrics that improve cross-border reliability.
- Regulated and participating non-regulated utilities experience clearer pathways for compliance and potential avoided costs through more efficient planning.
- Consumers and ratepayers may see more reliable service and better-aligned investment in infrastructure as IRP processes converge on best practices.
Who Bears the Cost
- Electric utilities and Transmission Organizations bear the cost of implementing enhanced modeling, data collection, and regulatory compliance associated with the guidelines.
- State energy offices and regulatory staff may incur upfront costs for staff training, data systems upgrades, and stakeholder engagement activities.
- Vertically integrated and participating municipal utilities may face short-term costs to align with updated IRP requirements and procurement decisions.
- Owners and developers of certain generation resources could experience shifts in anticipated project timelines or financing strategies due to updated planning assumptions.
- Ratepayers could face short-term costs if updated plans necessitate infrastructure investments not fully offset by efficiency gains.
Key Issues
The Core Tension
The central dilemma is balancing uniform federal guidance with diverse state market structures and regulatory regimes. The guidelines aim to standardize IRP while accommodating regional differences; the grant program seeks to accelerate modernization but risks uneven adoption if funding is insufficient or unevenly distributed.
The bill creates a centralized set of planning guidelines and a competitive grant program to modernize IRP processes across states and utility structures. While this fosters consistency and potentially improves reliability, it also raises questions about state sovereignty and the capacity of all states to implement complex analysis and data-driven planning.
The breadth of modeling approaches required may impose substantial upfront costs, and the reliance on probabilistic and scenario-based methods could lead to contested results that regulators must interpret carefully. There is also tension between public engagement requirements and the pace of regulatory action, as well as potential duplication with existing state processes and federal resilience initiatives.
The effectiveness of the grants will depend on state appetite for reform, the adequacy of funding, and the ability of stakeholders to integrate the guidelines into legally binding regulatory and procurement decisions.
