On Sunday 12 May, in the Netherlands, I estimate that 65% of all onshore wind production had to be curtailed.
Also large curtailments will have taken place for large scale solar and offshore wind.
Note: real time onshore wind data in ENTSO-E are from wind parks connected to the TSO network. These are mainly large wind parks.
Since most other wind parks in the NL are operated, on behalve of the owners, by companies with 24/7 dealing rooms, I expect a similar behavior for those parks.
