Energinet and Hitachi Energy have entered into a contract to develop Station Lindehøj, a new 420-kilovolt (kV) substation in Zealand that will be free of SF6.
This initiative is designed to enhance Denmark’s power grid and facilitate the incorporation of renewable energy while minimizing environmental impact.
“Station Lindehøj is set to serve as a pivotal center in the enhancement of the power grid in Zealand, enabling the management of increased volumes of renewable energy. Energinet is committed to minimizing our climate impact, even during the development of new infrastructure. Therefore, we are delighted to partner with Hitachi Energy, which offers a dependable and more sustainable technical solution that supports our objective of facilitating the green transition while being mindful of the climate and the environment,” states Kim Willerslev Jakobsen, CEO of Systemansvar at Energinet.
Sustainable development through EconiQ innovation:
The design of Station Lindehøj will incorporate 420 kV GIS equipment that is free from SF6. The agreement encompasses the design, engineering, construction, and installation of Hitachi Energy’s EconiQ technology, which utilizes an environmentally friendly gas mixture devoid of sulfur hexafluoride (SF6), a detrimental greenhouse gas. The implementation of a single bay of this advanced 420 kV GIS prevents the release of 1,200 kg of SF6 into the electrical grid, thereby significantly enhancing the sustainability of the electrical network at the voltage level where SF6 is predominantly utilized.
“We take pride in assisting Energinet in fostering a more sustainable energy future with our EconiQ 420 kV gas-insulated switchgear,” states Markus Heimbach, Managing Director of High Voltage Products at Hitachi Energy. “This SF6-free solution substantially diminishes the carbon footprint of the power grid while ensuring optimal performance and reliability, all within the same spatial requirements as traditional equipment. Through our partnership with Energinet, we are not merely constructing infrastructure; we are facilitating the transition to clean energy for future generations.”
Upgrading Zealand for a clean energy future:
Station Lindehøj is a key part of Energinet’s plan to expand the 400 kV transmission grid in Zealand and Lolland-Falster (DK2). This expansion aims to transport larger amounts of renewable energy from South Zealand and Lolland/Falster to the more consumption-heavy areas around Copenhagen and North Zealand.
The Danish Ministry of Climate, Energy and Utilities has granted Energinet the necessary authorization (§ 4 permission, the Act on Energinet) to continue the further planning of Station Lindehøj – including obtaining the necessary permits to establish the station.
About Energinet:
Energinet is the Danish national transmission system operator for electricity and natural gas. It is an independent public enterprise owned by the Danish state under the Ministry of Climate and Energy.
Energinet has some 1150 employees, and its headquarters are located in Erritsø near Fredericia in Jutland. The gas division is located in Ballerup near Copenhagen.
The main tasks are to ensure efficient operation and development of the national electricity and gas infrastructure as well as ensuring equal access for all users of the infrastructure.
