Energy Storage is Different

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.
