tv_txt: I 119th CONGRESS 1st Session H. R. 4338 IN THE HOUSE OF REPRESENTATIVES July 10, 2025 Ms. Leger Fernandez (for herself, Mr. Casten , Ms. Castor of Florida , and Ms. Ross ) introduced the following bill; which was referred to the Committee on Science, Space, and Technology A BILL To develop weather tools for electricity system planning and operational modeling, expand research on extreme weather event scenarios for energy utility companies and regulators, and for other purposes.

1. Short title This Act may be cited as the Weather-Safe Energy Act of 2025 . 2. Establishment of Weather-Safe Energy Platform and support for electricity system planning and operational modeling (a) Initial report on meteorological and extreme weather event data Not later than 6 months after the date of the enactment of this section, the Secretary shall submit to the appropriate congressional committees a report containing the following: (1) A summary of current efforts in federally funded research and development centers to develop the use of meteorological, hydrological, and extreme weather event data for energy system modeling. (2) A description of the specific actions that the Secretary shall take to carry out subsection (b). (b) Weather-Safe Energy Platform digital tool (1) In general The Secretary shall develop and maintain an open-access digital tool, to be known as the Weather-Safe Energy Platform (in this section, referred to as the Platform ), to provide high-resolution data of meteorological and hydrological variables suitable for electricity system planning and operational models. (2) Availability of Platform The Secretary shall make available the Platform not later than 2 years after the date of the enactment of this section. (3) Contents of Platform The Platform shall include the following, with respect to the United States: (A) Meteorological and hydrological variables derived from state-of-the-science atmospheric models used in international model intercomparison projects, regional forecasting datasets, and reanalysis data, as determined appropriate by the Secretary, at spatiotemporal resolutions suitable for electricity system planning and operational modeling. (B) Information that maintains spatiotemporal correlation of the meteorological and hydrological variables to ensure a realistic and reliable representation of conditions that may contribute to cascading failures of electricity systems. (C) Historical data and projections of meteorological and hydrological variables across short-, medium-, and long-term timelines, developed using methods that ensure consistency with standard practices for evaluating electricity system planning and operational decisions. (D) Sufficient information to provide for ensemble model scenarios that support narrative- or storytelling-based approaches to modeling current and future conditions and effects on electricity systems. (E) Up-to-date information provided by ongoing relevant research projects. (4) Stakeholder input The Secretary shall include input from stakeholders determined appropriate by the Secretary, including utility companies, municipalities, independent system operators, regional transmission operators, Federal and State regulators, and academic experts, to ensure the Platform meets the data needs of such stakeholders in the energy modeling activities of the stakeholders. (5) Fit-for-purpose data strategy The Secretary shall develop and implement a strategy to carry out the following: (A) Evaluate whether the data in the Platform are appropriate for specific electricity system planning and operation applications. (B) Ensure that each dataset in the Platform includes, or is accompanied by, clear and standardized metadata that includes information on best-practice use cases such as trend detection, uncertainty analysis, and the study of extreme event intensification. (C) Establish and implement procedures to regularly review and update datasets and the metadata of the datasets to account for and reflect advances in science and the evolving needs of stakeholders. (c) Research and modeling into extreme weather event scenarios (1) In general The Secretary shall take such actions, as determined appropriate by the Secretary, to support research projects to enhance the understanding and modeling of the changes to extreme weather events that affect the planning and operations of electricity systems. (2) Grants for increased research The Secretary shall make funds available, through grants made on a competitive basis, contracts, and cooperative agreements, to federally funded research and development centers, institutions of higher education, and other eligible independent research institutions (as determined by the Secretary) to carry out the research projects and modeling referred to in paragraph (1). (3) Integration of research findings into the Platform The Secretary shall integrate into the Platform such findings from the research projects and modeling referred to in paragraph (1) to assist energy utility companies and regulators with respect to planning for, and responding to, changes in extreme weather events. (d) Technical assistance (1) In general The Secretary shall provide training resources and technical assistance to utility companies, grid operators, municipalities, State regulators, and other interested stakeholders. (2) Goals In carrying out paragraph (1), the Secretary shall carry out the following: (A) Offer workshops, training sessions, and distribute educational materials to stakeholders to improve understanding of how meteorological and hydrological variables and extreme weather events affect electricity system planning and operations. (B) Provide technical assistance with respect to the following: (i) Utilizing the tools and resources available through the Platform. (ii) Integrating scenario data into electricity system planning and operational models. (C) Facilitate collaboration and the exchange of knowledge among stakeholders to identify best practices for electricity system planning and operations with respect to changes in meteorological and hydrological variables and changes in extreme weather events. (e) Reports to Congress Not later than 5 years after the date of the enactment of this section, and on a periodic basis thereafter not less frequently than every 3 years, the Secretary shall submit to the appropriate congressional committees a report containing descriptions of the following: (1) The funds used to carry out this section, including grants made pursuant to subsection (c). (2) The outcomes achieved through such grants. (3) The development and deployment of the Platform. (4) The advancements in the research carried out pursuant to subsection (b). (5) The extent to which utility companies, grid operators, and Federal and State regulators have utilized the Platform. (6) The activities and effects of the training resources and technical assistance provided under subsection (d). (f) Implementation The Secretary shall carry out— (1) subsections (a) and (c) through the Office of Electricity of the Department of Energy, in consultation with such agency heads as determined appropriate by the Secretary; and (2) subsections (b) and (d) through research and development centers funded by the Secretary.
