The system is able to balance the use of energy as it is in high demand in the daytime and at low usage at night. It compresses the air for storage at night when the energy load is low then releases the high-pressure air to generate energy for the peak-time use.
The system generates a maximum of 40,000 kWh electricity each day, equivalent to the electricity consumption of 3,000 household for a day.
