Any must match electricity production to consumption, both of which vary significantly over time. Energy derived from and varies with the weather on time scales ranging from less than a second to weeks or longer. is less flexible than , meaning it cannot easily match the variations in demand. Thus, without storage presents special challenges to . Projects with a nameplate capacity of 20 MW or less typically experience much faster processing times, with a median processing time of 18 months for projects between 5 MW and 20 MW, decreasing further to 11 months for projects sized five MW or smaller.
