The “Duck Curve” The “Duck Cur e” Duck‘ Duck‘s N Neck • In the late afternoon / early evening hours, the net load curves quickly ramps up to produce an “arch” similar to the neck of a duck • Ramp (aka flexible generation capacity) is attributed to demand peaks when the sun goes down and solar generation tapers off • As more renewable resources come online, the ramp gets steeper Duck‘ Duck‘s Be Belly • In Spring, the net load curves produce a “belly” appearance in the mid-afternoon • Due to low demand and the influx of renewables, oversupply results which can lead to overgeneration • During oversupply times, wholesale energy prices can be very low and even go negative 23
