Companies with large power requirements may still struggle to secure sufficient grid capacity in Lolland-Falster and South Zealand, even though Energinet is planning a major expansion.
The so-called Green Grid is scheduled to be expanded in two stages towards 2029 and 2033 and is expected overall to roughly triple transmission capacity between Lolland-Falster and Zealand.
Energinet has not disclosed how much of the total increase in capacity will come from each stage.
- There are capacity challenges both when electricity needs to be imported into the area and when power needs to be transported out of the area, says Kim Willerslev Jakobsen, CEO of Energinet System Operator.
Energinet’s assessment comes after the company stated that regional grid constraints will persist for several years, while a number of projects in the area are planning significant electricity consumption. Milence is developing a public charging hub for lorries near Nørre Alslev, while the proposed data centre near Rødbyhavn could, according to project documents, require more than one gigawatt at full build-out.
Lolland-Falster’s large production of green electricity does not in itself mean there is room for new companies with high consumption. They must also be supplied when the sun is not shining and the wind is not blowing.
- In these operating situations, energy may, for example, have to be transported from international interconnectors and onwards through the electricity grid in South Zealand and Lolland-Falster, where there are currently capacity constraints, says Kim Willerslev Jakobsen.
While the grid remains under pressure, the way companies use electricity could affect their access to capacity. A proposal still under consultation would make it possible to prioritise projects based, among other things, on the strain they place on the grid. Publicly accessible charging facilities are among those given high priority.
Companies may also be considered more grid-friendly if they accept restricted grid access and are able to reduce consumption when the network is heavily loaded. The rules have not yet been adopted.
