Large-scale battery stations — mostly lithium-ion systems with up to four hours of energy storage capacity — are growing by the gigawatts on an annual basis.
After adding 1,665 MW of resources in the first three quarters of 2021, energy storage developers plan to install more than 3,600 MW in the final quarter of the year, according to S&P Global Market Intelligence data. That would result in roughly 5.3 GW of power storage capacity, marking by far the biggest year yet in the scale-up of alternatives to pumped hydroelectric storage. It is estimated that developers plan to deliver nearly 9 GW in 2022 and over 10 GW in 2023
