Wind Power Generates 140% Of Denmark’s Power Demand

July 13th, 2015 by  


Wind power generated 140% of Denmark’s electricity demand last Thursday, which allowed the country to export some of its power to neighboring Norway, Germany, and Sweden.

News of the record-breaking generating figure has been swimming around news outlets and social media. The Guardian appear to have broken the news, at least in the mainstream, last Friday.

According to figures, Denmark generated 116% of the nation’s electricity needs from wind turbines. By 3am on Friday morning, with the winds still blowing strong, that figure had increased to 140%. As the graph below shows, interconnectors allowed for 80% of the power surplus to be shared between Germany and Norway, while Sweden took about a fifth of the 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, speaking to The Guardian. “Wind energy and renewables can be a solution to decarbonisation – and also security of supply at times of high demand.”

Denmark’s wind energy success was recently highlighted in a report by the European Commission Joint Research Centre, in its annual report on wind energy technology, along with Portugal, Ireland, Spain, Romania, and Germany, as countries generating between 10% and 40% of their electricity from wind energy.

Similarly, in the middle of June Denmark announced a new tender round for 350 MW of near-shore wind farms off the east coast of Jutland.

The Guardian quoted Kees van der Leun, the chief commercial officer of the Ecofys energy consultancy, who believes that a recent surge in wind turbine installations could help Denmark produce half of its electricity demand from renewable energy sources well before 2020.

“They have a strong new builds programme with a net gain of 0.5GW in new onshore windfarms due before the end of the decade,” he said. “Some 1.5GW from new offshore windfarms will also be built, more than doubling the present capacity. We’re seeing a year-on-year 18% growth in wind electricity, so there really is a lot of momentum.”

    Actually, Denmark generates 2,141 megawatts with oil, 1,059 megawatts with natural gas, and 2,401 megawatts with coal for a total of 5,601 megawatts from fossil fuels.

  • Sam C. Syvertsen

    Norway is close to 100% hydropower with storage capacity of 90 TWh in dams. The part exported to Norway is thus stored indirectly stored in the dams as hydropower production in Norway is throttled down.

    • Ulenspiegel

      That is the way to go, in Norway and Sweden there are more than 15 GW dispatchable hydrpower, very likely 10 GW in the alps.

      Providing sufficinet transmission capacity (15 GW to Norway/Sweden) is by far the cheapest solution to store surplus PV production from central Europe.

      • Foersom

        Norway has (from my memory) 31 GW dispatchable hydro capacity.

        • Ulenspiegel

          Even better. It is interesting how different the numbers for Scandinavia are in various studies. 🙂

          What is the pump capacity?

          • Foersom

            Norway has no real pumped storage, less than 100 MW?

            Remember that pumped storage require even more special topology. You need a lake of equal size both below and above.

            Norway may have pumped storage in future.

            By 2020 both Germany and Britain will be conned with HVDC to Norway. Search for ENTSOE 2014 ten year plan for Europe grid.

          • Ulenspiegel

            I know the planned HVDC lines, we Germans need 0.5 MW per year. 🙂

            OTOH Norway increases windpower (with hydropwer already able to provide 110% of demand) which only makes sense when they can export electricity at higher capacity.

            I hope for a win-win situation.

          • Sam C. Syvertsen

            Not exactly, downstream it is enough to have a river. You don’t need to store what is used.

        • Sam C. Syvertsen

          There is difference between dispatchable and total capacity. With a dam behind you have a “battery”. Without you have to more or less produce what comes down the river.

    • jeffhre

      Yep, Denmark is the model for the giant wind power provider, and Norway is the model for the giant hydro battery. Wait, what is the meaning of baseload again?

  • Matt

    YoY growth of 18% ! Looks like Denmark plans to make some euros on electric exports.

    • Jan Veselý

      No, they just have an excellent use for surplus production – they make heat, easy to be stored, easy to be sold and used. But of course, they are able to sell surplus a ruin the economy of inflexible Swedish nuclear power plants.

      • juxx0r

        Hopefully those nuclear power plants can cry me a river and then put in some dams to said river and then create hydropower. Which they can then sell to Poland and then they can shut down the coal power stations.

        • Jan Veselý

          No way, Polish government is afraid of its coal miners. So they build phase shifters on German border and subside their unproductive and technically obsolete coal mining.
