Berlin – The feed-in of 13,212 megawatts (MW) worth of wind power on Thursday evening signified the first time the line of
13,000 MW was exceeded in the grid of 50Hertz, the transmission system operator responsible for the north-east of Germany. Around 9 PM, its system management registered the new feed-in record caused by hurricane Theresa. The previous record for the 50Hertz grid dated back to 21 December last year, when the feed-in reached a height of 12,832 megawatts.
According to first estimates, a total of over 31,000 MW of wind power was integrated in the German grids yesterday evening and last night. This could only be done securely through considerable interventions in the output of conventional as well as wind power stations. At its peak, almost 6,000 MW of electricity generated by conventional units within the 50Hertz grid had to be redispatched yesterday evening (i.e. reduced in one place and increased accordingly elsewhere). Output from wind turbines in the 50Hertz area was temporarily lowered to about 1,800 MW.
Based on the first analyses, 50Hertz assumes that the supply rate for the north-east of Germany approached 60 to 70 per cent and at certain points even more as a result of the high wind power feed-in yesterday evening and last night. System security was nevertheless guaranteed at all times. The share of renewable energy in the consumption of electricity within the 50Hertz area amounted to 49 per cent in 2015. For this year, the system operator expects it to exceed 50 per cent.
