Impact of demand on a daily load curve

Demand-side response is one of several measures that can help integrate higher shares of variable renewables, including electricity storage, greater interconnection and more flexible power plants.

When the sun is shining and the wind blowing, electricity generation from these sources may exceed demand, leading to the curtailment of otherwise low-cost and carbon-free electricity. Inversely, when the wind doesn’t blow or on cloudy days, power systems may need to rely on flexible yet expensive and carbon-intensive sources of generation.

Demand-side response can significantly reduce such outcomes by shifting and shaping electricity demand to match the availability of renewables-based electricity generation.
