Battery storage is having its moment in the sun.
In its most recent Electricity Monthly Update, the U.S. Energy Information Administration said that when it totals up the numbers for 2021, it expects they will show that battery storage capacity grew by 4.5 GW, or 300%, in the year just ended.
“Declining cost for battery storage applications, favorable economics when deployed with renewable energy (predominantly wind and solar PV), and value-added additions in regional transmission organization (RTO) markets have helped drive the expansion of battery storage,” the EIA said.
