This bill amends the Energy Act of 2020 to significantly bolster the safety of energy storage technologies across various programs. It expands the objectives of the Energy Storage System Research, Development, and Deployment Program to include developing models, tools, and diagnostic data sets aimed at improving safe installation and long-term operation. These new objectives specifically target the abatement of expected failure modes, such as component failure, thermal runaway, and fire and explosion risks, alongside the development of early detection and preventative maintenance techniques. A key provision mandates comprehensive and standardized testing and validation of energy storage systems, including test-bed trials and field tests. This involves developing methodologies for evaluating storage technologies under various operating and failure conditions, performing grid performance testing, and conducting reliability, safety, degradation, and durability testing. Crucially, the bill requires component, module, and integrated system-level stress testing to failure , particularly for operational grid-connected systems installed before the most recent safety codes. The bill also adds the United States Fire Administration and the National Institute of Standards and Technology as key partners for leveraging resources in these efforts. The legislation extends the deadline for energy storage demonstration projects to 2030 and increases the minimum number of required projects from three to five, with at least two new projects specifically dedicated to furthering safety through stress testing. It also expands the selection requirements and objectives of the Energy Storage Pilot Grant Program to prioritize improving the safety of operational systems through advanced testing, data utilization, and the development of safer chemistries. Finally, the bill authorizes an appropriation of $30,000,000 for each of fiscal years 2027 through 2031 to fund these enhanced safety programs and initiatives.
