Integrated Resource Planning Modernization Act

Sponsored By: Representative Leger Fernandez, Teresa [D-NM-3]

Introduced

Summary

Modernize integrated resource planning for the U.S. power system by directing the Department of Energy to publish national IRP guidelines and to help states update planning, modeling, and coordination. The bill would pair those guidelines with grants and training to bring state plans in line with modern reliability and clean-energy tools.

Show full summary
  • States would be eligible for DOE grants to implement IRP modernization. First grant applications could be submitted not later than six months after the guidelines are published and grants must be used within five years.
  • Utilities, transmission organizations, and grid operators would get technical assistance and training and could receive grant funding for modeling, staffing, software, stakeholder engagement, and to help recover compliance costs.
  • Planners would be asked to use iterative capacity expansion, transmission-inclusive modeling, probabilistic resource adequacy, interregional collaboration, extreme weather scenarios, and scorecards that compare costs, reliability, and sustainability across scenarios.

Bill Overview

Analyzed Economic Effects

3 provisions identified: 3 benefits, 0 costs, 0 mixed.

Grants to states for grid planning

If enacted, DOE would run a grants program to help states modernize integrated resource planning, if Congress provides funding. The Secretary would set grant amounts using factors like a state’s plan quality, number of customers, and utility and grid mix. Restructured states would need to work with utilities and grid operators on a strategy that follows DOE guidelines. Vertically integrated states would need to update rules to follow the guidelines and help utilities comply. States could use funds for staff, consultants, modeling software, public input, and to reimburse utilities and grid entities for implementation costs. States could apply starting within 6 months after DOE posts the guidelines, must report progress within 2 years after receiving funds, and must use the money within 5 years.

National guidelines for power grid planning

If enacted, the Department of Energy would publish power‑grid planning guidelines within 2 years after enactment. The guidelines would cover modeling, transmission, storage, distributed and behind‑the‑meter resources, demand‑side steps, interregional sharing, and extreme‑weather risks. They would use scenarios, probabilistic methods, and scorecards to compare costs, reliability, and other impacts. DOE would offer training and technical help and coordinate with other federal programs. DOE would review and update the guidelines at least every 5 years and report to Congress within 5 years and every 5 years after.

Who is covered by grid planning rules

If enacted, the bill would define key terms for the program. It would spell out what counts as behind‑the‑meter steps (like home efficiency, rooftop solar, batteries, and demand response) and distributed energy resources. It would define transmission organizations, balancing authorities, restructured states, and vertically integrated states. It would also define how to measure capacity value for power plants, demand‑side steps, and transmission or grid‑enhancing technologies.
