Abstract: A large-scale energy storage facility that includes autonomous energy storage towers for housing cells in a manufacturing stage. Electrical energy is selectively stored in the cells from an energy source or grid as reserve energy by providing. This is performed during an inventorying stage of a manufacturing process of the cells. The energy storage includes a charge cycle that is exploited in a quality assessment process of the cells. The energy is selectively retrieved for provision back to the grid or energy source in a discharge cycle which is also exploited for quality assessment of the cells. A highly energy efficient and cost-effective framework is thus obtained from the architecture.
