How Energy Storage Works in Peak Shaving. Energy storage systems, such as lithium-ion batteries, work by storing excess energy produced during low-demand hours, typically overnight or during the day when electricity prices are lower. This stored energy can then be used later during peak hours, when the price of electricity is higher.
