November 20, 2025
Mr. Casten (for himself, Mr. Mullin, Mr. Huffman, Mr. Subramanyam, Mr. Quigley, Mr. Garamendi, Ms. Castor of Florida, Mr. Moulton, Mr. Foster, Mr. Levin, and Mr. Carson) introduced the following bill; which was referred to the Committee on Energy and Commerce
To require standardized performance reporting for entities engaged in electricity transmission to improve transparency, accountability, and grid outcomes, and for other purposes.
Section 1. Short title
This Act may be cited as the Electricity Transmission Scorecard Act
.
Sec. 2. Findings
Congress finds the following:
(1)
Electricity transmission facilities and services provided by covered transmission owners affect interstate commerce and are essential to the Nation’s economic well-being and national security.
(2)
Transparent, standardized performance data on transmission systems promotes cost-effective investment, prevents unduly discriminatory practices, and protects ratepayers.
(3)
Existing reporting requirements are fragmented, inconsistent, and do not allow for meaningful comparison among transmission providers, RTOs, and ISOs.
(4)
To ensure that all transmitting utilities are subject to uniform, non-discriminatory access obligations, to safeguard the public interest in the reliability, affordability, and efficiency of the interstate transmission system, and to ensure the development of just and reasonable rates, a common performance reporting framework is necessary.
(5)
Systemic transparency across all utilities engaged in transmitting electricity enables ratepayers, investors, generators, regulators, researchers, and other stakeholders and market participants to clearly compare transmission rates, outcomes, and practices across regions and governance structures.
(6)
Market and policy innovation in the electricity sector is enhanced by making grid performance data publicly available, thus empowering independent research, enabling competition, and reducing information asymmetries between utilities and external actors.
(7)
The quality of economic, reliability, and environmental outcomes delivered to customers can improve as a result of performance-based accountability.
(8)
It is in the best interest of the Nation to require standardized data submissions and scorecard reporting from all utilities engaged in transmitting electricity, including those not subject to section 205 or 206 of the Federal Power Act, to evaluate whether service comparability and nondiscrimination obligations are being met and to ensure that ratepayers are not burdened by inefficiencies, lack of investment, or the absence of cost-effective solutions that would increase capacity, reduce congestion, facilitate interconnection, or otherwise reduce unnecessary costs and reliability concerns for ratepayers.
Sec. 3. Performance scorecard elements and verification
(a) Reporting requirements
(1) Transmission Investment, Accountability, and Performance Scorecards
(A) In general
The Commission shall require each covered transmission owner to biannually develop, publish, and submit to the Secretary a report, to be known as a Transmission Investment, Accountability, and Performance Scorecard (or a TIAPS report), that includes metrics evaluating the following:
(i)
Ratepayer affordability, which shall assess the cost of transmission services per unit of energy transmitted or other metrics that can be used to assess affordability of energy provided to ratepayers.
(ii)
Financing costs, which shall assess the financing structure and cost of capital for a covered transmission owner, and may include consideration of capital structure and leverage ratios, reliance on formula rates or other automatic adjustment mechanisms, allowed and earned returns on equity, the cost of debt and preferred stock, the presence and magnitude of incentive rate adders, and other related metrics.
(iii)
Investment prudency and cost recovery, which shall assess the prudency of capital investments and the transparency and structure of associated cost recovery mechanisms, and may include the frequency and magnitude of cost disallowances in rate proceedings, the types of facilities or investments associated with disallowed costs, the degree of cost recovery from ratepayers relative to shareholder contributions, and the transparency and accountability of cost allocation frameworks.
(iv)
Investment effectiveness, which shall assess the value delivered by covered transmission owner investments relative to their costs, including how effectively the covered transmission owner considered and deployed the most economically efficient solutions to reduce cost burden on ratepayers and the accuracy of project cost estimates, and may include metrics related to benefit-cost analyses, investments in advanced technology deployment, non-wires alternatives, reconductoring, grid-enhancing technologies, or other operational upgrades that avoid higher cost capital investment, estimated and actual cost for new or updated assets, and other indicators of prudent capital deployment.
(v)
Capital expenditure bias, which shall assess the covered transmission owner’s balance of spending on capital investment versus operational and maintenance activities.
(vi)
System reliability and availability, which shall assess the operational performance of the transmission facilities of the covered transmission owner over the reporting period, including information related to outages, equipment availability, and resilience to system disturbances, and may be expressed using existing transmission-specific reliability indicators, as described by the North American Electric Reliability Corporation or other entity established to oversee and administer reliability standards and procedures for the bulk-power system, metrics regarding the economic costs of outages or lost reliability, or other related metrics.
(vii)

(BB)
is not an affiliated entity.
(ix)
Non-operational cost recovery, which shall assess the amount of covered transmission owner spending on lobbying, advertising, penalties, and advocacy activities recovered through customer rates, and may be expressed as expenditures on each such activity, a total sum of expenditures on such activities, or related metrics.

the Commission determines are necessary to improve transparency, affordability, reliability, equity, or environmental performance of the facilities owned, operated, or controlled by the covered transmission owner.
(B) Exemptions
(i) Categories
The Commission may, by rule, exempt all covered transmission owners in a category of covered transmission owners from the requirement to include a metric described in subparagraph (A) if the Commission determines that the metric is demonstrably inapplicable to all covered transmission owners in the category.
(ii) Scope
The Commission shall ensure that the scope of any metric from which a category of covered transmission owners is exempted under this subparagraph is as narrow as possible in order to preserve consistency and comparability among scorecards.
(C) Coordination
