Reinforcing the Grid Against Extreme Weather Act of 2025

Sponsored By: Representative Casten, Sean [D-IL-6]

Introduced

Summary

Expand and coordinate interregional transmission capacity to make the grid more reliable against extreme weather, physical attacks, and cyber threats. The bill would require the Federal Energy Regulatory Commission to set uniform measurement rules, a minimum transferable capability between adjacent planning regions, and a process for selecting and paying for interregional projects.

Show full summary
  • Families and households would see stronger electric reliability and better access to lower-cost generation when regions share capacity, which can reduce outages and congestion risks.
  • Regional transmission planners and grid operators would have to file coordinated plans every 3 years, use uniform methods to measure transfer capability, and meet a minimum transferable capacity to address resilience.
  • Utilities and developers would face a new project selection and cost-allocation regime that identifies interregional transmission projects and assigns costs based on quantified transmission benefits.

Bill Overview

Analyzed Economic Effects

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

New rules to move power between regions

If enacted, the Federal Energy Regulatory Commission (FERC) would issue rules within 24 months. The rules would require one shared method to measure how much power can flow between neighboring regions. They would set a minimum transfer level to keep the grid reliable during extreme weather, physical problems, or cyberattacks. The rules would also set how to pick interregional projects and who pays for them. Sensitive cyberattack information would be protected from disclosure. Utilities, grid owners, and planners would need to follow these rules.

Regular regional grid plans and oversight

Adjacent regional planners would file an interregional plan with FERC within 3 years of enactment. They would update plans at least every 5 years. Plans must meet the minimum transfer levels and select projects based on defined transmission benefits. FERC would approve or deny plans using those factors, including reliability during extreme events. If projects result, costs would be allocated under the new rules.

Public reports and clear planning definitions

FERC would publish a report in the Federal Register within 48 months after issuing the rules. It would publish a new report every year after. Reports would show progress toward meeting minimum transfer levels and selecting projects. The bill would also add definitions, effective on enactment. It defines greenhouse gases, transmission benefits, transmission planning entities, and transmission planning regions. These definitions would guide the rulemaking and plan reviews.
