UL 9540, the Standard for Energy Storage Systems and Equipment, covers electrical, electrochemical, mechanical and other types of energy storage technologies for systems intended to supply electrical energy. . age systems for uninterruptible power supplies and other battery backup systems. First, EES reduces electricity costs by storing electricity obtained at off-peak times when its price is lower, for use at peak times instead of electricity bought then at higher prices. Secondly, in order to improve the reliability of the power. . 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. The Standard covers a comprehensive review of ESS, including charging and discharging. . 1.
