Electric companies are increasingly using innovative technologies such as energy storage, hydrogen, and microgrids to develop a smarter energy grid that delivers energy safely and reliably to customers.

Energy storage offers multiple benefits to the energy grid and electricity customers. It facilitates the integration of renewable energy resources, such as wind and solar, into the grid by keeping supply and demand balanced at all times. Energy storage also helps to improve reliability by providing grid stability services, reducing transmission constraints, and meeting peak demand. 

Long-duration energy storage (LDES) can help improve the resilience of the energy grid by providing backup power during natural disasters or other emergencies. LDES can also provide other grid services such as frequency regulation, voltage support, and black start capability, contributing to the overall stability and efficiency of the power system.

Energy storage, including hydrogen as a storage medium, can be integrated into microgrids. This not only gives customers greater control over their energy needs, but also helps electric companies enhance the resilience of the entire energy grid. Furthermore, it provides numerous public benefits that extend beyond microgrid users to the general grid and all customers.

Key Facts

Electric companies are the largest users and operators of the approximately 40 gigawatts (GW) of operational energy storage in the U.S., representing 93 percent of all energy storage capacity in use today.
