New transmission lines: who pays? FERC gets vague rules to decide.

What it does

This bill amends federal power law to allow companies building large interstate or offshore transmission lines (1,000+ megawatts, or expansions adding 500+ megawatts) to file tariffs with the Federal Energy Regulatory Commission (FERC) that allocate construction costs to customers in the regions that benefit from the line. The bill requires cost allocation to be 'roughly commensurate' with estimated benefits and to account for reliability, economic, public policy, resilience, and environmental factors. It does not change FERC's authority over smaller transmission projects.

Why we flagged it

The bill's core function is to establish a regulatory mechanism for how large transmission projects allocate their costs across regions and customers. It is not a subsidy, mandate, or prohibition—it is a procedural rule for tariff filing and cost apportionment under federal power law.

What the text implies

• The 'roughly commensurate' standard is subjective and may allow utilities to allocate costs to regions with less political power or lower regulatory scrutiny, shifting burden away from wealthier or more organized customer bases.
• The bill does not require public hearings, cost-benefit analysis disclosure, or ratepayer consent before tariffs are filed, potentially enabling cost allocation decisions to proceed without transparent deliberation.
• By allowing cost allocation across 'applicable transmission planning regions,' the bill may enable utilities to spread costs across state lines, complicating state-level regulatory oversight and consumer protection.
• The definition of 'reasonably anticipated benefits' is not constrained by statute, giving FERC and utilities broad discretion to classify intangible benefits (resilience, public policy alignment) as justification for cost allocation, potentially inflating customer bills.

Who it affects

The bill may lower costs for consumers in regions that benefit from new transmission capacity by spreading costs fairly across beneficiaries rather than concentrating them on one utility or region. However, the vague standard ('roughly commensurate,' 'reasonably anticipated benefits') creates discretion for utilities and FERC to shift costs to ratepayers in ways that may not reflect actual benefits, and the bill does not mandate transparency or public participation in cost allocation decisions.

Who stands to gain

• transmission developers and operators
• utilities with transmission assets
• large-scale renewable energy developers (who benefit from transmission expansion)
