In some energy markets, daily peak demand occurs after sunset, whenis no longer available. In locations where a substantial amount of solar electric capacity has been installed, the amount of power that must be generated from sources other than solar or wind displays a rapid increase around sunset and peaks in the mid-evening hours, producing a graphthat re. The duck curve is a graph that shows the imbalance between peak electricity demand and solar power generation12. It resembles a sitting duck, with solar energy flooding the market during the day and dropping off in the evening1. The term was coined in 2012 by the California Independent System Operator2. As more solar energy is exported to the grid, the curves deepen, potentially causing power system instability3.
