The Solar Power Duck Curve Explained

But the introduction of solar power has brought about problems in these demand curve models. Since solar power relies on the Sun, peak solar production occurs around midday, when electricity demand is often on the lower end. As a result, energy production is higher than it needs to be, and net demand—total demand minus wind and …

The duck curve and how energy storage can beat it

If California is to reach its goal of carbon-free electricity generation by 2045, increased use of battery energy storage is sure to play a major part. According to one analysis, California will need to install almost 49 GW of energy storage—five times the output of all utility-scale batteries currently operating worldwide—to meet that target.

Load Curve

Daily Load Curve. A daily load curve has the load variations that are plotted during the whole day (24 hours) on a half-hourly or hourly basis and are plotted against time on the graph. The figure below displays a daily load curve. On the X axis hours in a day are presented, while on the Y axis load units in MW are presented.
