With the shortage of power generation capacity reserve and a series of severe conditions, from heat wave, drought, wildfire to tropical storm, the United States grid faces a huge power outage risk in the summer and autumn. In response, builders of utility scale battery storage plants are competing to start and operate new projects.

Data shows that, if the plans of developers and utilities are successful, the total installed capacity of U.S. utilities (excluding conventional pumped storage plants) has increased 185% to 5582MW (about 5.6GW) year on year as of August this year.
