release it when production levels do not meet the requirements. Only then can we rely on‚ say‚ wind or solar power as our primary sources of energy . There are other reasons why it is necessary to store large amounts of energy. Depending on how storage is distributed‚ it may also help the network withstand peaks in demand. Storing energy allows transmission and distribution to operate at full capacity‚ decreasing the demand for newer or upgraded lines. Storing energy for shorter periods may be useful
