In 2021, the transmission system operator TenneT transmitted round 20.3 terawatt hours (TWh)*) of offshore wind power from the German North Sea to land. In purely arithmetical phrases, this may cowl the annual demand of greater than six million households with inexperienced power. The annual outcome for 2021 is under a earlier yr’s worth for the primary time: in 2020 it was nonetheless 22.76 TWh. The decline is primarily because of climate circumstances, as 2021 was a low-wind yr general. In Germany, complete onshore and offshore wind energy era reached 114.37 TWh in 2021 (earlier yr 129.63 TWh). The share of North Sea electrical energy rose to 17.8 p.c (earlier yr 17.6 p.c).
TenneT COO Tim Meyerjürgens mentioned: “In Germany, the share of North Sea electrical energy in complete wind energy era now accounts for nearly one fifth and is proving to be a stabilising consider years with weak winds. On common, we generate round twice as many full-load hours offshore as onshore and might thus partially compensate for lulls on land. Lately, nonetheless, there was no enhance in offshore wind energy. We subsequently welcome the plans of Federal Minister of Economics Robert Habeck to provide precedence to offshore growth sooner or later and to strengthen co-utilisation and cross-border initiatives within the course of.”
The emergency programme introduced by the Federal Minister of Economics might give the power transition the urgently wanted momentum it must get again on monitor and obtain the formidable local weather safety targets, mentioned Tim Meyerjürgens. “The strategy of built-in, forward-looking planning of the varied grid infrastructures can also be right – as a result of that is the prerequisite for reaching local weather neutrality in 2045. For this, we urgently want fashionable, environment friendly planning and approval procedures. The purpose should be to make planning as quick as building. There are sufficient levers to be tightened, for instance, standardisation of species safety and nearer dovetailing of regional planning and planning approval procedures. On the identical time, it will be important that the federal government ensures that we now have the required political assist for implementation on the bottom and that we collectively marketing campaign for acceptance,” Tim Meyerjürgens harassed.
Within the Netherlands, the transmission capability of TenneT’s offshore grid connections quantities to 1,503 MW **). These transmitted 4.71 TWh in 2021 (earlier yr 1.82 TWh). The sturdy enhance in comparison with the earlier yr is principally because of the truth that the commissioning of the Borssele Beta offshore grid connection system solely occurred within the second half of 2020. An additional 3.53 TWh was fed straight into the Dutch TenneT grid onshore by Dutch offshore wind farms in 2021. In complete, virtually twice as a lot wind power was thus produced offshore within the Netherlands as onshore. The entire onshore wind power capability within the Netherlands is 4,500 MW, which generated 4.41 TWh in 2021.
The most recent will increase in local weather targets and electrical energy demand expectations are resulting in ever larger technical challenges for TenneT as a transmission system operator. TenneT is going through as much as this and is working efficiently and at full velocity on additional grid growth on land and at sea. TenneT already operates greater than half of all offshore grid connections within the EU. By 2030, TenneT will realise 16 extra after which present virtually 29 gigawatts of wind energy transmission capability within the North Sea. In the identical interval, TenneT will make investments round 20 billion euros within the Netherlands and Germany for this function.
Additional offshore stability information
Within the German North Sea, the utmost worth of the feed-in capability of offshore wind farms in 2021 was measured on 29 January at 6,357 megawatts (MW).
The capability growth of offshore wind farms within the German North Sea was 6,679 MW on the reporting date of 31 December 2021, with no change from the earlier yr. TenneT’s offshore transmission capability is 7,132 MW within the German North Sea.
Wind generators within the German Baltic Sea (50Hertz grid space) generated 3.7 terawatt hours in 2021 (earlier yr 4.13 TWh), in order that Germany’s complete offshore era on this interval was 24 terawatt hours (of which North Sea 20.3 TWh). Including 90.37 terawatt hours*) of onshore wind power generated, the entire yield in Germany involves 114.37 terawatt hours*) (earlier yr 129.63 TWh).

The onshore electrical energy portions for the months October to December 2021 partly embrace preliminary estimated values.
