H.R. 6633House119th Congress (2025-2027)Passed House

High-Capacity Grid Act

Introduced December 11, 2025

AI-Generated Summary

Updated September 17, 2026 at 4:44 AM UTC

The High‑Capacity Grid Act amends the Federal Power Act to require the Federal Energy Regulatory Commission (FERC) to mandate that public utilities use the "best‑available" transmission conductors on new or major transmission projects. The rule aims to improve the amount of power a line can carry, its efficiency, and its mechanical performance, affecting utilities that build or upgrade transmission lines under FERC’s jurisdiction.

Key Provisions

  • FERC must issue regulations within one year that set a method—developed with the Energy Secretary—to identify conductors with the highest feasible capacity, efficiency, and mechanical performance at each voltage level.
  • Public utilities must file required information to show they are using conductors designated as best‑available for any new construction or major upgrade/replacement of transmission lines.
  • Exemptions apply if a utility had already filed for permits or bought conductors before the law took effect, for emergency repairs after disasters or terrorism, if safety or reliability would be compromised, or if the higher‑cost conductors would not provide a material benefit relative to the increase in electricity cost.
  • FERC may periodically review and update both the designation methodology and the list of best‑available conductors as technology improves.

2d Session

H. R. 6633

IN THE SENATE OF THE UNITED STATES

September 16, 2026

Received; read twice and referred to the Committee on Energy and Natural Resources

AN ACT

To establish a best-available transmission conductor standard for certain transmission projects under the Federal Power Act and to provide for presumptions regarding cost recovery for such conductors.

1.

Short title

This Act may be cited as the High-Capacity Grid Act.

2.

Best-available transmission conductor class

The Federal Power Act is amended by inserting after section 223 (16 U.S.C. 824w) the following:

224.

Use of best-available transmission conductors

(a)

Use of best-available transmission conductors

In exercising its authority under sections 205 and 206, the Commission shall require that public utilities use transmission conductors that are designated as part of the best-available transmission conductor class when carrying out covered projects.

(b)

Regulations

(1)

In general

Not later than 1 year after the date of enactment of this section, the Commission shall issue regulations to carry out this section.

(2)

Inclusions

In issuing regulations under paragraph (1), the Commission shall—

(A)

establish, in consultation with the Secretary of Energy, a methodology to designate, as part of the best-available transmission conductors class, transmission conductors that—

(i)

provide the greatest feasible and commercially available energy-carrying capacity at a given voltage level;

(ii)

provide the highest feasible and commercially available electrical efficiency at that voltage level; and

(iii)

provide the greatest feasible and commercially available level of mechanical performance, taking into account relevant factors, including reliability, safety, and affordability;

(B)

using such methodology, designate transmission conductors as part of the best-available transmission conductor class;

(C)

establish filing requirements for public utilities to demonstrate compliance with the regulations, including (as applicable) such information and data the Commission determines necessary to demonstrate project-specific impacts described in subparagraph (D); and

(D)

provide that the requirement to use transmission conductors that are designated as part of the best-available transmission conductor class not apply—

(i)

to carrying out any covered project for which a public utility, prior to the date of enactment of this section, has—

(I)

filed for any State or Federal permit required to carry out the covered project; or

(II)

procured any transmission conductors;

(ii)

to the emergency replacement or repair of transmission facilities necessary to restore service following a natural disaster, act of terrorism, or other event designated as an emergency by a relevant Federal or State authority;

(iii)

if such use would negatively impact safety or violate a reliability standard; or

(iv)

if the public utility carrying out the covered project demonstrates such use would significantly increase the cost per kilowatt-hour of electricity without providing a material and commensurate increase to capacity, efficiency, or mechanical performance.

(c)

Periodic review and updates

The Commission may, to reflect improvements in technology, periodically review and update—

(1)

the methodology for designating transmission conductors as part of the best-available transmission conductor class; and

(2)

the designation of transmission conductors as part of the best-available transmission conductor class.

(d)

Definitions

In this section:

(1)

Best-available transmission conductor class

The term best-available transmission conductor class means a class of transmission conductors that are designated as part of the class pursuant to this section.

(2)

Commission

The term Commission means the Federal Energy Regulatory Commission.

(3)

Covered project

The term covered project means—

(A)

the construction of a new transmission facility subject to the jurisdiction of the Commission under section 201(b) that includes a transmission conductor; or

(B)

any major (as determined by the Commission) modification, upgrade, replacement, or reconductoring of an existing transmission conductor subject to such jurisdiction.

(4)

Reliability standard

The term reliability standard has the meaning given such term in section 215.
