Introduction
Across October and November, fourteen new battery energy storage systems received full approval from ERCOT to begin commercial operations.
In all four load zones in ERCOT, at least two batteries were able to begin commercial operations.
However, installed capacity increased the most in the West and North Load Zones, shown on the map below in red and yellow, respectively. Between October and November, more than of new battery energy storage capacity was completed in both the West and the North.
