Denmark’s high level of wind penetration allowed the Nordic country to meet all of its electricity needs with a significant surplus spared for Germany, Norway and Sweden, too.
On 9th July 2015, Denmark produced so much excess wind power that not only was it able to meet its own electricity needs but also able to export power to Germany, Norway and Sweden.
Thursday was an exceptional windy day when Denmark found itself generating 116% of its national electricity needs from wind turbines. As the demand dropped by 3:00 am on Friday, the figure has risen to 140%.
Thankfully, Germany and Norway equally shared 80% of the power surplus between them and stored it in hydropower systems for use later. The remaining fifth of excess power was taken by Sweden.
Oliver Joy, a spokesman for trade body the European Wind Energy Association was overjoyed at the fact that a world powered by 100% renewable energy is not a distant dream anymore. Wind energy and renewables can be a powerful solution to decarbonization as well as a backup in times of high demand.
An excess of electric power from wind turbines means Denmark will be producing half of its electricity needs from renewables well before the set target of 2020. The country also has plans to build new onshore & offshore wind farms by the end of the decade, which will see a year-on-year 18% growth in wind electricity. If we have to see this success on a European scale, the renewable industry needs to have a strong government backing, upgraded grid infrastructure and increased interconnection to trade electricity on a single market.
