In fact, Danish wind turbines generated what corresponds to 42% of country’s electricity consumption, making Denmark the leading country in wind power generation. It also held the world record in 2014 with 39% of country’s total electricity consumption coming from wind.
The percentage is even higher is western Denmark, where the majority of wind turbines are located. They generated electricity corresponding to 55% of the consumption in this part of the country. In eastern Denmark, the respective figure was 23%.
According to the statistics, Denmark also had the highest wind power share in any hour in 2015 (138.7%), whereas in 2014 the figure was 132.1%.
One of the main reasons for 2015 being a record year was the fact that it was very windy. This record was achieved even though two offshore wind farms were offline for a total of three months during the year due to cable faults!
As shown in the diagram below, the wind power share in the country’s power system has been constantly increasing since 2008. It is worth mentioning that the target for 2020 has been set to 50%.
Wind power share of power consumption over the last decade
For 409 hours during last year, the Danish electricity system produced more wind power than the total consumption. This allowed greater imports and exports of electricity across its borders. Surplus wind energy is sold to consumers in Norway, Sweden and Germany. Conversely, Denmark buys hydroelectric power from Norway, solar energy from Germany and power station electricity from Sweden, when necessary.
One whole day based only on renewables and CHP plants
For the first time ever, on September 2nd, 2015 the western Danish power grid operated without energy supply from central power stations, relying solely on wind turbines, solar cells, local CHP plants and imports!
All the above show that renewable energy can be really efficient and will play an even more significant role in the future. Well done Denmark!
