The largest electricity customers in the Copenhagen area, North Zealand and parts of Central Zealand used 21.1 percent more electricity last year than in 2024. This is shown by new figures from the grid company Radius, which owns the electricity grid in the area.
According to the company, the increase is due to more production companies and heating supplies switching to electricity, while new charging stations and electrification for both new and existing customers are also driving the development. In total, Radius' largest customers used 1,514 GWh in 2025.
- For some years, we have had a dialogue with various sectors that have had a desire to connect to the electricity grid for the benefit and benefit of companies, society and the climate. It is a process that may take time, but now many of these customers are starting to be electrified, and this is helping to raise consumption among our largest customers, says Cäthe Bay-Smidt, Head of Function at Cerius-Radius, in a press release.
As a result of the increasing demands on the electricity grid, the two eastern Danish grid companies, Radius and Cerius, invested a total of more than three billion DKK in the electricity grid in 2025. The investments in new cables and transformer stations are to ensure that the electricity grid can handle the development and support the green transition.
- It is a huge task to ensure that the electricity grid can handle the development among the largest customers. We are dealing with individual customers who alone can make the same demands on the electricity grid as an entire provincial town, says Cäthe Bay-Smidt.
