Unusually high winds allowed Denmark to meet all of its electricity needs – with plenty to spare for Germany, Norway and Sweden too
On July 9, Denmark’s wind farms generated more than enough power to meet nationwide electricity demands — with a whopping 40% surplus overnight.
Due to an unusually windy day, wind farms in Denmark managed to produce 140 per cent of the country’s electricity needs.
By Thursday evening, the Nordic nation’s wind turbines were producing 116 per cent of Denmark’s electricity needs, a figure that rose to 140 per cent in the early hours of the morning.
80 per cent of the surplus power was shared between Germany and Norway, with Sweden taking the 20 per cent left over according to a report by The Guardian.
Interconnectors allowed 80% of the power surplus to be shared equally between Germany and Norway, which can store it in hydropower systems for use later. Sweden took the remaining fifth of excess power.
“It shows that a world powered 100% by renewable energy is no fantasy,” said Oliver Joy, a spokesman for trade body the European Wind Energy Association. “Wind energy and renewables can be a solution to decarbonisation – and also security of supply at times of high demand.”
The figures emerged on the website of the Danish transmission systems operator, energinet.dk, which provides a minute-by-minute account of renewable power in the national grid. The site shows that Denmark’s windfarms were not even operating at their full 4.8GW capacity at the time of yesterday’s peaks.
