To ensure safety, performance, and interoperability, the International Electrotechnical Commission (IEC) developed the IEC 62933 series, a set of globally recognized standards. As renewable energy adoption grows, energy storage systems (ESS) have become critical for balancing supply and demand, improving reliability, and supporting grid resilience. Department of Energy's National Nuclear Security Administration under contract. NFPA is keeping pace with the surge in energy storage and solar technology by undertaking initiatives including training, standards development, and research so that various stakeholders can safely embrace renewable energy sources and respond if potential new hazards arise. It is critical to plan for the future, today.
