Wind power maximums
During the month of November wind power energy exceeded the historical maximums for instantaneous power, hourly energy and daily energy. On 9 November the instantaneous production of wind power energy reached 14,962 MW at 2.46 pm, 13.5% more than the previous record, registered on 8 November. That same day the hourly and daily energy maximums were also exceeded, with 14,752 MW and 315,258 MWh, respectively.
