Duck curve

The Duck Curve
Blue curve: Demand for electrical power
Orange curve: (the duck curve) supply of electrical power from dispatchable sources,
Gray curve: supply of solar electrical power
Data is for the State of California on October 22, 2016 (a Saturday),[1] a day when the wind power output was low and steady throughout the day.
The orange curve rises steeply from 17:00 to 18:00 as the sun sets, requiring about 5 gigawatt of generating capacity from dispatchable sources to come on line within one hour.

The duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and solar power generation. The graph resembles a sitting duck, and thus the term was created.[2] Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator.[3][4]
