Siemens Energy wins expansion agreement to future-proof Denmark’s electricity grid

Siemens Energy and Danish state-owned Energinet have announced a 1.4 billion framework agreement to renew Denmark’s energy infrastructure in order to help accelerate the green transition.

Siemens Energy has been chosen by Energinet to deliver transformers and switchgears for high-voltage substations to expand the electricity grid in the country.

The agreement focuses on the Western part of Denmark, where approximately 50 new or reinforced 150 kV high-voltage substations are planned to be built or expanded over the next 8 years. The first four years of the agreement is estimated to be worth up to 800 million euros (DKK 6 billion) to accelerate the energy transition. The new substations will be automated and include state-of-the-art grid technologies from Siemens Energy.

With Denmark aiming to reach a target of net zero emissions by 2045 through renewable energy, the race is on to decarbonise the Danish grid. By 2030, the country must quadruple its electricity generation from wind and solar power as electricity consumption is multiplied by the switch to electrical vehicles, heat pumps, and converting solar and wind power to hydrogen and green fuels for industries. These shifts require massive investment and expanding electricity grids to ensure the future electrification of Danish society.

“There is no energy transition without transmission, and that can only happen with the availability of switchgears and transformers” said Tim Holt, Member of the Executive Board for Siemens Energy. “Grid investments are accelerating dramatically in Europe and worldwide, and customers are competing for manufacturing slots. This agreement enables Siemens Energy to plan its capacities, which will benefit both Danish and European energy infrastructure. We are excited to be trusted to deliver on the grid acceleration in Denmark.”

As renewable energy becomes a bigger part of the electricity mix, grids need to adjust how to transport that electricity. Unlike with conventional generation, wind and solar are often not available where they are consumed, which means the electricity needs to be transported over longer distances, usually at high voltages to minimise loss. Power transformers are a crucial link in this chain, as they enable both that long-distance transport, as well as the conversion between high-voltage for transporting and lower-voltage for consumers.

“We need external suppliers to ensure rapid and significant expansion of the electricity transmission grid” added Henrik Riis, CEO of Energinet Electricity Transmission. “The task is enormous. In the coming years, several high-voltage substations on the ‘high-ways’ of the Danish electricity grid are needed to secure that renewable electricity can be connected to the grid and transported around the country. We are incredibly pleased that with Siemens Energy we get a long-term, strategic partnership, thus ensuring that we can keep up with the dramatic development in Denmark.”

The new agreement is the continuation of a long-standing partnership between Siemens Energy and Danish Energinet, the independent public enterprise owned by the Danish Ministry of Climate, Energy and Utilities which owns, operates, and develops the transmission systems for electricity and gas in Denmark. This includes the recently inaugurated Viking Link, the world’s longest interconnector between Denmark and the UK.
