How does curtailment affect wind and solar energy projects?

Curtailment of variable renewable generation, particularly wind and solar energy, is becoming more widespread as wind and solar energy development expands across the country and penetrations increase. Curtailment can affect the revenue of wind and solar energy projects.

Will wind and solar power curtailment become a necessity?

With increasing shares of wind and solar power, curtailment might also become a necessity at some point, but this is not foreseen for the near future. A study on future curtailment in the Nordic power system has found that curtailment will gain significance in Sweden and Denmark before eventually reaching Norway .

Does wind power curtailment affect energy system composition and operation?

With an increasing share of variable renewable energies in the power production, curtailment may become relevant to better manage the power system. Here, we explore the effects of wind power curtailment on the energy system composition and operation on two levels: national (Finland) and city level (Helsinki).

What are Wind Energy Curtailment levels?

Curtailment levels have generally been 4% or less of wind energy generation in regions where curtailment has occurred. A notable exception is ERCOT, where curtailment levels reached 17% in one year, primarily because wind generation came online ahead of transmission capacity. These levels have since receded to less than 2%.
