The cost of a flywheel energy storage system varies based on several factors, including size, design, and installation requirements. On average, the price range for such systems falls between $400 to $900 per kilowatt-hour of energy storage capacity. Reducing greenhouse gas emission in the electricity sector at the lowest possible cost. Supporting California's loading order to meet energy needs first with energy efficiency and demand response, next with renewable energy (distributed generation and utility scale), and finally with clean. FESS is used for short-time storage and typically offered with a charging/discharging duration between 20 seconds and 20 minutes. Key drivers include technological advancements, high efficiency, low maintenance costs, and environmental benefits. The purpose of this study is to determine the capabilities and cost-effectiveness of a lower-cost-of-manufacture Flywheel Energy Storage (FES) System. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the.
