Energinet’s board has approved a plan to construct two completely new North Jutland high-voltage stations, which will make it possible to connect much more electricity production from, among other things, solar cells. The stations will together cost more than DKK 1.1 billion. DKK and an application have now been sent to the Ministry of Climate, Energy and Supply.

Energinet is now applying to the Ministry of Climate, Energy and Supply for permission to expand the electricity grid in North Jutland with two brand new high-voltage stations for a total value of over 1.1 billion kroner.

Energinet’s board has approved a plan for the two projects. Due to the size of the amount, the ministry must process and finally decide on the expansion plans.

The electricity grid must be expanded

There are plans for new, green electricity production all over the country. Solar parks, in particular, are booming. The electricity is produced to a far lesser extent than previously at power plants near the big cities and consumption centres, but instead in parts of the country where there is neither local consumption nor the electricity grid enough for the enormous production. Therefore, the electricity transmission network must be expanded in many places. And since in the future, we will also need more power for many more things – e.g. for electric cars, heat pumps and the production of green hydrogen – and electricity production will come “as the wind blows” and “the sun shines” – the power grid must be able to transport much more power over much longer distances.

Brønderslev and Aalborg

Therefore, the plan is to build a brand new high-voltage station in the area south of Brønderslev and a brand new high-voltage station in the area northeast of Aalborg. The stations will each have a capacity of 1,100 MW. 2,200 MW corresponds to the two stations being able to receive electricity which corresponds to approximately one-third of all of Denmark’s current maximum electricity consumption.

“Right now, we know of concrete plans for solar parks that will be able to deliver approx. 700 MW in the Brønderslev area and approx. 850 MW in the Aalborg area, but we also know that more green electricity production is on the way. Denmark must become independent of fossil energy and imports of energy from Russia at record speed. That is why the solar area, in particular, is developing very quickly. It is important that we get ahead of the development and, to a much greater extent, have the courage to build ahead – the need will probably come, and it is far too expensive to arrive too late – even if there can be uncertainty about the exact final need”, says Stine Grenaa Jensen, deputy director of Energinet.

In June, the Norwegian Parliament adopted the “Climate Agreement on Green Power and Heat 2022”, which implies that power from solar cells and wind turbines on land must be quadrupled by 2030.

The entire network is examined

Energinet has discussed the expansion of the electricity transmission network with municipalities and business organizations in North Jutland on several occasions over the past year. There is a great desire in North Jutland for a green conversion of, e.g. business, and therefore a desire to expand the electricity grid. Therefore, Energinet is working in parallel with the two new, large high-voltage stations, for which permission has now been applied for to build, to investigate the needs for expansion of the rest of the electricity transmission network in North Jutland.

“There are many thoughts and plans about both green electricity production and new large electricity consumption – for example, companies that need a lot of power – in North Jutland. Therefore, we are examining the entire electricity grid structure in North Jutland so that, on the one hand, we ensure that the electricity grid is expanded in the places where it is needed, but on the other hand, we do not build more electricity grid than is needed in the future,” says Stine Grenaa Jensen.

“Aalborg East” will also be expanded

Energinet has also recently expanded an existing 150 kV high-voltage station, “Aalborg East”. It is from the early 1970s and is reaching the end of its lifespan and must therefore be replaced by a new one. In this connection, it has been decided to double the capacity in connection with the current station’s reinvestment to accommodate more electricity consumption and production and ensure electricity supply in the future.
