A decade ago, large-scale battery storage was considered the mythical Holy Grail to solving renewable energy’s intermittency woes with sunshine and wind. The early pilot projects remained in their infancy—too expensive to rapidly ramp up.
Today, technology advances and dramatic cost decreases combine to set up battery energy storage as the savior for both renewables and the overarching electric grid as power demand soars and Congress rapidly phases out tax credits for wind and solar energy.
