The U.S. electricity grid needs grid energy storage. U.S. adoption of grid-energy storage can be accelerated through enhanced grid-energy storage facility (facility) communication, and decision-making technologies. Enhanced communication and decision-making technologies results in enhanced facility control. Enhanced facility control can be used to optimize facility function for battery life and demand-curve smoothing. Optimizing facility operations for battery life is vital for ensuring the safety and reliability of grid energy storage facilities. Lithium-ion batteries are less likely to experience catastrophic failure when operated in a manner that maximizes their useful life. It is important to understand how batteries deteriorate with use and under different operating conditions to operate the facility in a way that optimizes safety and battery life. Demonstrating facility reliability can further accelerate the deployment of grid energy storage, leading to smoother energy demand curves and increased utilization of renewable energy. Optimizing facility reliability through enhanced facility control systems will reduce the strain on the electrical grid. Ultimately, realizing these benefits requires a thorough understanding of how operating conditions impact battery deterioration and a robust facility control system capable of optimizing facility operation for battery life. Therefore, the key to accelerating the adoption of grid-energy storage is developing communication and decision-making technologies that optimize facility function. Optimizing facility function not only benefits battery life and demand-curve smoothing, but also enhances safety and reliability. The deterioration of Li-ion batteries over time is influenced by their operation, making it crucial to understand how operating conditions affect battery deterioration. To optimize facility operation for battery life, a system of facility control is necessary. Therefore, the key to accelerating the adoption of grid-energy storage is the development of communication and decision-making technologies that optimize facility function. Optimizing facility function not only benefits battery life and demand-curve smoothing, but also enhances safety and reliability. To achieve this, a deep understanding of how operating conditions affect battery deterioration is necessary. In order to optimize facility operation for battery life, a robust and sophisticated system of facility control is required.
