Duck curve
Timing imbalance of energy demand and solar power generation
Duck curve
The duck curve is a graph showing the electricity demand remaining after subtracting electricity supplied by variable renewable energy sources (primarily solar) over the course of a day. This highlights the timing imbalance between demand and solar power generation, which must be filled by dispatchable generation. The curve is named for its visual similarity to the outline of a duck. Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator.
