01 — The Text
What.
- Requires FERC to presume best-available transmission conductors are prudent and cost-recoverable for new, modified, or replaced interstate transmission lines
- Presumes non-best-available conductors are not prudent and costs are not reasonable
- Defines best-available conductor by three criteria: greatest energy-carrying capacity, highest electrical efficiency, and maximum thermal sag mitigation at rated capacity
- Applies to utilities' filings seeking cost recovery through electric rates
02 — The Stakes
So what?
- The bill shifts the evidentiary burden in FERC rate proceedings by establishing presumptions rather than requiring utilities to prove prudence and reasonableness
- Utilities using best-available conductors would face a reduced burden to recover those costs through consumer rates
- Utilities using other conductors would face a presumption their costs are unreasonable, requiring rebuttal evidence
- Effect on consumer rates and electricity costs depends on how utilities respond to these presumptions and FERC's application of them—not established by the bill
03 — The Path
Now what?
- House passed bill by voice vote under suspension of rules on September 15, 2026
- Received in Senate and referred to Committee on Energy and Natural Resources on September 16, 2026
