01 · The brief
Plain-English summaryWhat this bill actually does

This bill amends Section 40101 of the Infrastructure Investment and Jobs Act to (1) define and require use of reliability metrics (SAIDI, SAIFI, CAIDI) including outages over five minutes and Major Event Days in calculations; (2) require grant-making (by DOE, States, and Tribes) to give additional weight to applicants with worse reliability (higher SAIDI/SAIFI/CAIDI) over the prior five years; (3) prohibit conditioning grants on addressing more than one category of eligible activities or preferring applications solely for addressing multiple categories; and (4) extend the program’s availability period from 2022–2026 to 2027–2031, funds to remain available until expended.

Why people may split

Watch point

Relative to its intended legislative type, this bill is a narrowly focused substantive amendment that (1) extends the authorization period for the IIJA program, (2) adds specific reliability metrics (CAIDI, SAIDI, SAIFI) and a standard reference for their calculation, and (3) requires grantmakers to give additional weight to entities with poorer historical reliability while prohibiting conditioning applications on addressing multiple activity types.

Content is narrowly technical and broadly noncontroversial, but enactment depends on appropriations and packaging into larger legislation.

Who stands to gain, and who may push back.

Likely benefits vs burdens50% / 50%
Federal agenciesLikely burdened

These are examples from the analysis, not a ranked list of the most-affected groups.

Likely helped
  • Federal agenciesTargets federal grants to utilities and areas with poorer reliability based on standardized indices.
  • Potential benefitAdopting IEEE 1366 metrics improves comparability and transparency of outage reliability reporting.
  • Potential benefitExtending program availability through 2031 provides multi-year funding continuity for resilience projects.
Likely burdened
  • Potential burdenIncluding Major Event Days and outages over five minutes may inflate indices and alter funding priorities.
  • Potential burdenEntities that improved reliability previously could receive lower priority for future grants.
  • Potential burdenCalculating and reporting standardized indices imposes administrative and data burdens on utilities and agencies.
03 · Why people split

Why the argument around this bill splits.

Progressives emphasize targeting worst-off grids and counting Major Event Days
Progressive90%

Likely supportive because the bill targets resilience funding to communities and systems with worse reliability and requires counting major-event outages.

It narrows gatekeeping that could exclude smaller or single-focus projects.

The extension keeps federal resilience support active.

Leans supportive
Centrist65%

Cautiously favorable if the metrics are implemented with clear standards and strong data verification.

The bill pragmatically focuses resources where interruptions are worse and reduces unnecessary application complexity, but details on budget and oversight matter.

Split reaction
Conservative30%

Skeptical of continued federal grant programs and of prioritizing applicants for poor past performance.

Concerns focus on federal micromanagement, potential perverse incentives, and ongoing federal spending without explicit appropriation increases.
