Energy transition started in the 1970s in Denmark with the oil shocks, and the country has dedicated to include low-carbon energy in its grid to acquire energy independence via national energy planning.
Currently, 40% of Denmark’s electricity comes from wind, and the country’s target is to reach 50% by 2020 and 100% renewables by 2050. A steady policy commitment to clean energy has enabled Denmark’s grid to be more reliable than most European countries despite its high percentage of wind power.
Troels Gregersen, Nordics energy expert at PA Consulting Group said: “The system operator and the whole energy system are constantly being developed to accommodate the fact that we are going away from fossil centralized production capacity to renewables.”
Denmark is now a global wind power leader with 42% of its energy from wind. Energinet.dk is Denmark’s grid operator and it controls and plans the supply and generation of electricity for the country.
Denmark works closely with Norway, Sweden and Germany, to which it can transfer up to 6.4 GW of electricity, and from which it can buy solar or hydropower if it lacks wind power.
Energinet.dk is expanding its capacity and additional interconnections are planned to Germany and the UK with the 1.4-gigawatt capacity Viking Link. This will represent the largest submarine cable in the world at 740 kilometres and it is able to transport annual electricity consumption of 2.7 million households.
The expansion of the grid operator will not only help balance the wind supplies but it is expected to bring billions in profits for the country.
