The Weather-Safe Energy Act of 2025 aims to enhance the resilience of electricity systems against extreme weather by establishing a comprehensive framework for data, research, and technical assistance. It mandates the creation of an open-access digital tool , the "Weather-Safe Energy Platform," within two years of enactment, providing high-resolution meteorological and hydrological variables, historical data, and future projections suitable for electricity system planning and operational models. The Platform will incorporate state-of-the-science atmospheric models and reanalysis data, maintaining spatiotemporal correlation to represent conditions that could lead to cascading failures. The Secretary of Energy will gather input from diverse stakeholders, including utility companies and regulators, to ensure the data meets their specific needs, and will develop a strategy for data evaluation and metadata standardization. The bill further directs the Secretary to support research projects focused on understanding and modeling changes in extreme weather events affecting electricity systems, making funds available through competitive grants. Findings from this research will be integrated into the Platform to aid utility companies and regulators in planning and response. Additionally, technical assistance, including workshops and training, will be provided to stakeholders to facilitate the Platform's use and integrate scenario data into their models. Periodic reports to Congress will detail funds used, outcomes achieved, Platform development, research advancements, stakeholder utilization, and the effects of technical assistance, with implementation primarily through the Department of Energy.
