Utility-scale battery storage systems have storage capacity which ranges from few megawatt-hours to hundreds of megawatt-hours. Technologies such as lithium-ion, sodium sulfur, and lead acid batteries are used for grid applications. Among these technologies, the lithium-ion battery market has grown in the last few years.
Utility-scale batteries play an important role in facilitating the next stage of energy transition. The battery storage system provides grid services such as frequency response, regulation reserves, and ramp rate control.
