NKT expands its medium-voltage plant in Denmark
NKT completed the expansion of its medium-voltage cable (MV) plant in Asnaes, Denmark, with a new production hall, additional testing facilities, and improvements to the production flow. The project, started in September 2024, is now operational, and its production ramp-up will continue over the coming months.
The expansion added more than 100 new jobs to the plant, which now employs around 300 people and has been manufacturing MV cables since 1965.
Carlos Fernández, Executive Vice President and Head of Distribution at NKT, described the completion as a “relevant technical milestone” that strengthens the company’s capacity to modernize power grids, integrate renewables, and advance electrification. The inauguration ceremony is scheduled for August 2026.
Asnaes closes a coordinated plan across three countries
What the press release does not highlight is that Asnaes is not an isolated investment: it is the third and final piece of an approximately €100 million plan announced in April 2024, which also included the plants in Falun, Sweden, and Velké Meziříčí, Czech Republic; both completed in January 2025.
The three investments are calibrated to specifically expand the 20 to 110 kV range, the voltage segment that connects medium-scale solar and wind farms to the grid, and not the high voltage of large transmission links.
This calibration responds to capacity constraints: according to the International Energy Agency, meeting national climate goals requires adding or renovating more than 80 million kilometers of power grids by 2040, while the European Union estimates it will need to invest €584 billion this decade just to modernize its grids.
NKT, in parallel, is investing another €50 million in its Esposende plant, acquired together with SolidAl, confirming that the medium-voltage segment—and not generation—has become the limiting link in the European energy transition.
With the four plants already underway or completed, NKT aims to sustain a return on capital employed (RoCE) above 20% in its Applications business line, which generated €842 million in revenue in 2025 and employs 2,300 people across six European countries.
