Unprecedented results for Offshore Wind generation in Denmark, as unusually high winds allowed Denmark to meet all of its electricity needs – with plenty to spare for Germany, Norway and Sweden too!
Danish transmission systems operator, energinet.dk provides minute-by-minute information on the output of renewable power to the national grid, and on Thursday 9th July they recorded Denmark's wind turbines producing 116% of its national electricity needs. By 3am on Friday, when electricity demand dropped, that figure had risen to 140%.
This was enough to export 80% of the power surplus to be shared equally between Germany and Norway, which can store it in hydropower systems for use later. With Sweden taking 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 EWEA (European Wind Energy Association). “Wind energy and renewables can be a solution to decarbonisation – and also security of supply at times of high demand.”
This comes after the announcement by David Cameron in the UK that his government are looking to withdrawal support for onshore windfarms from next year, and planning obstacles for onshore wind builds.
For the UK to build a robust and sustainable energy industry for the future, one in which it can both manufacture and construct developments on it's own shores and waters, it requires more not less government investment?
A surge in windfarm installations means Denmark could be producing half of its electricity from renewable sources well before a target date of 2020, according to Kees van der Leun, the chief commercial officer of the Ecofys energy consultancy.
Joy said: “If we want to see this happening on a European scale, it is essential that we upgrade the continent’s ageing grid infrastructure, ensure that countries open up borders, increase interconnection and trade electricity on a single market.”
Around three-quarters of Denmark’s wind capacity comes from onshore windfarms, which have strong government backing.
