Danish power transmission system operator Danish national power data show that in 2017, January-August Germany - Denmark available cross-border power capacity doubled year on year, an average of 496 MW.
However, cross-border power capacity in August fell to less than 500 megawatts from a record high of 730 megawatts in July.
In the fourth quarter of last year, 1780 megawatts of cross-border power capacity averaged less than 100 megawatts.
Due to the stability of the grid, the high density of wind turbines between the two countries has severely limited the cross-border capacity.
In June, the two energy ministers agreed to gradually increase the available cross-border power capacity to 1.1 GW in 2020, from the minimum capacity guaranteed in July to 400 megawatts in November.
In 2018, the minimum available cross-border power capacity negotiated by the two countries was 700 megawatts. While the available capacity in 2016 averaged only 192 megawatts.
With the expansion of the German power grid is expected to be able to successfully remove the bottleneck, in 2020, the two sides agreed to a minimum transaction capacity of 1.1 GW.
The background condition of these measures is the growing regional imbalance within Germany. Due to the prosperity of the northern wind power and the gradual closure of the southern nuclear power plant, leading to Germany's new North-South interconnection project is very slow.
In the next 10 years, Germany plans to invest 50 billion euros for the national grid expansion plan, including the new sea interconnection, but most of the plan will not be completed by 2025, and six nuclear power plants in 2021/22 years is expected to lead to the final Power grid problem deteriorated.
According to the Norwegian national grid, the new 1.4-watt interconnection project to Germany will take five years to transition and is expected to be put into operation in 2020.
On average, the price of Nordic is cheaper than that of Germany and the European continent because of the abundant hydropower resources in Norway and Sweden, the nuclear power plants in Sweden and Finland, and the growing wind power market.
