World Energy Storage Day is commemorated on 22nd September every year by various global industry stakeholders, policy makers, think tanks and associations to acknowledge its importance across the globe.
The Autumnal equinox occurs on 22rd September and the day and night are of approximately equal duration i.e. the day is balanced.
With a rising focus on the effective integration of renewable energy, the importance of electric vehicle and reliable, resilient energy supply, energy storage is becoming an increasingly important tool in the electricity ecosystem.
Energy storage has played a huge role in grid balancing, power supply-demand management and frequency regulation and to acknowledge the balancing effects of Energy Storage, 22nd September was chosen as an apt date for the World Energy Storage Day.
