Correction to: Nature Energy https://doi.org/10.1038/s41560-018-0281-2, published online 26 November 2018.

In the version of this Article originally published, the labels for the colour scales in Fig. 4 were mistakenly swapped. The label in panel a should have read ‘Power deficit (MW)’ and the label in panel b should have read ‘Wind speed deficit (m s–1)’. This has now been corrected.
