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 generalThe 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 PlatformThe Secretary shall make available the Platform not later than 2 years after the date of the enactment of this section.(3)Contents of PlatformThe 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 inputThe Secretary shall include input from stakeholders determined appropriate by the Secretary, including utility companies, municipalities, independent system operators, regional transmission

data strategyThe 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 generalThe 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

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 generalThe Secretary shall provide training resources and technical assistance to utility companies, grid operators, municipalities, State regulators, and other interested stakeholders.(2)GoalsIn 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 CongressNot 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

committeesThe term appropriate congressional committees means the following:(A)The Committee on Energy and Commerce of the House of Representatives.(B)The Committee on Energy and Natural Resources of the Senate.(2)Ensemble modelThe term ensemble model means a collection of multiple simulations used to estimate uncertainty in projections of meteorological phenomena, including extreme weather events, that provides a range of possible outcomes with respect to such phenomena.(3)Extreme weather eventThe term extreme weather event means severe and abnormal earth system phenomena that can significantly affect the operations of electricity systems, including hurricanes, coastal or inland flooding, wildfires, snowpack or permafrost thaw, and extreme droughts.(4)Institution of higher educationThe term institution of higher education has the meaning given that term in section 101 of the Higher Education Act of 1965 ( 20 U.S.C. 1001 ).(5)Meteorological and hydrological variablesThe term meteorological and hydrological variables includes temperature, humidity, wind speed, solar radiation, precipitation, streamflow, and other atmospheric and water-related measurements.(6)Open-access digital toolThe term open-access digital tool means a computational resource, including software, datasets, and modeling frameworks, that is designed to support energy system resilience planning and operational decision-making that is publicly available without restrictions to access, use, or distribution.(7)SecretaryThe term Secretary means the Secretary of Energy.(8)Spatiotemporal correlationThe term spatiotemporal correlation means the statistical relationship between variables across both space and time that ensures consistency in modeling the effect of extreme weather events on energy systems.(9)Spatiotemporal resolutionThe term spatiotemporal resolution means the level of detail in which data elements are represented across space and time that is appropriate for energy system modeling and analysis.(10)State-of-the-scienceThe term state-of-the-science means the most advanced and validated knowledge, methods, or technologies available in
