## 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. - 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.

## Provisions PRIA read

- New rules to move power between regions: benefit, high. 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, physica…

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 fac…

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 de…
