As the electricity grid continues to evolve, energy storage will increasingly become a critical, reliable, and flexible resource for utilities and electricity end users alike.
Energy storage provides safe, clean, and emission-free electrical capacity to help increase grid reliability, prevent forced black- and brown-outs during periods of high system use, and provide better grid integration of an ever-increasing amount of intermittent renewable generation.
Energy storage is able to provide firm, guaranteed energy output during periods of peak usage while often occupying an optimized and smaller footprint compared to potential alternatives.
In short, the unique attributes of energy storage allow it to either completely replace traditional solutions or greatly improve their efficiency and efficacy.
