Varmahlíð substation

Due to plans for increased energy consumption in Sauðárkrókur, it’s intended to strengthen the site’s connection to the transmission system and increase energy delivery and security of supply by laying a 66 kV underground cable, Sauðárkrókslína 2, from Varmahlíð to Sauðárkrókur in Skagafjörður.

Two new substations will be built, in Sauðárkrókur and Varmahlíð. The substation in Sauðárkókur houses four 66 kV switch gear bays. The existing substation will be closed. The substation in Varmahlíð houses five 66kV switch gear bays. Sauðárkrók’s only connection to the transmission system is 66 kV line from Varmahlíð, which is over 40 years old.

The only connection Saudarkrokur to the transmission system is 66 kV air line from Varmahlíð, which has just over 40 years old. The underground cable will increase energy security and more than double the area’s capacity, and it’s intended to be 24 kilometers long. The existing overhead line, Sauðárkrókslína, will be connected by a underground cable to the substation in Sauðárkrókur.

Verkís is responsible for the design, project management, making of tender documents and quantity calculation, assistance in contracting, design supervision and assistance during construction time.

The Challenge

Growing electricity demand in Sauðárkrókur highlighted the need to strengthen the region’s ageing transmission infrastructure and improve security of supply. The project required new substations and a modern underground transmission connection to increase network capacity and provide a more resilient electricity supply for future development.

Our Solution

Verkís provided comprehensive engineering services, including design, project management, tender documentation, quantity surveying, procurement support, design supervision and construction assistance. The project includes the design of new 66 kV substations in Varmahlíð and Sauðárkrókur, together with a 24 km underground transmission cable to replace the area’s sole ageing overhead connection.

The new transmission infrastructure will more than double the electricity transfer capacity to Sauðárkrókur while significantly improving reliability and security of supply. Through integrated engineering and project management, Verkís is helping modernise the regional transmission network and create a robust electrical infrastructure capable of supporting future growth.
