The duck curve—named after its resemblance to a duck—shows the difference in electricity demand and the amount of available solar energy throughout the day. When the sun is shining, solar floods the market and then drops off as electricity demand peaks in the evening. The duck curve is a snapshot of a 24-hour period in

energy storage, the remaining energy storage amounts receive diminishing incremental capacity values. For example, energy storage added between 13,034 MWs and 15,795 MWs receives an average of only 59.7% capacity value. At precisely 15,795 MW, marginal battery capacity provides capacity value of 54.2%.

Renewable energy technologies are expected to take the leading role in the forthcoming energy generation portfolio in order to achieve sustainable energy generation. The major constraints for increasing penetration of renewable energy sources is their availability and intermittency, which can be addressed through energy storage when
