6 FAQs about [National wind power curtailment rate]

How much does wind curtailment cost UK?

How do wind curtailment rates relate to total VRE?

Analyzing wind curtailment rates in relation to total VRE gives a better picture of the integration challenge – both wind and solar may give rise to curtailment needs through congestion of transmission, for example. Wind power plants are usually larger and thus easier to control by the system operator if a period of curtailment is required. Fig. 8.

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).

Are curtailment rates a share of VRE and power system demand?

This paper gives a comparison overview of the curtailment rates, presented as C-E maps (curtailment as a share of VRE and power system demand). As previous statistical data was as until 2020, some data has been updated.

The amount of wind power “curtailed” in the first 11 months of 2024 stood at about 6.6 gigawatt hours (GWh), according to official figures, up from 3.8 GWh in the whole of last year. Curtailment is where wind turbines are paid to switch off at times of high winds to stop a surge in power overwhelming the grid.

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 .
