Duck Curve Solar Energy

The difference in the duck curve and a regular load chart is that the duck curve shows two high points of demand and one very low point of demand with the ramp up in between being extremely sharp.

Duck curve solar energy. When the sun is shining solar floods the market and then drops off as electricity demand peaks in the evening. 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. Solar energy s duck curve intermittent renewable generating technologies i e. It looks like a duck.

Everyone who cares about solar energy should know about the duck curve. The moniker quickly gained traction in the industry especially with emerging energy and environmental policy initiatives pushing for higher levels of solar pv deployment. The long story is below but the short story is. Solar energy production peaks at mid day and this causes demand for other energy to drop off.

The increasing issue of duck shaped net demand curve and its associated challenges is already visible and the challenge of effectively managing it without resorting to re curtailment will magnify as we continue adding infirm re capacity. Intermittent renewable generating technologies i e. Wind and solar are causing havoc with electric grid operations because these technologies cannot be controlled by the operators of the electricity grid due to the fact that their generation depends on the wind blowing and the sun shining. The term was coined in 2012 by the california independent system operator.

Solar energy s duck curve. Since renewable energy has become more common over the years the duck curve is appearing more often and is getting worse. August 23 2020 12 07 ist. Researchers in california call this seeming drop in demand the duck curve.

In utility scale electricity generation the duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and renewable energy production. Plus it s fun to say. Wind and solar are causing havoc with electric grid operations because these technologies cannot be controlled by the operators of the electricity grid due to the fact that their generation depends on the wind blowing and the sun shining. The official duck chart first published by caiso in 2013 what the duck curve tells us about managing a green grid.
