ABB has won an order worth around $11 million from the Swedish utility Svenska kraftnät to design, manufacture, and supply a submarine cable system under the bay of Edsviken in northern Stockholm.
The link is part of the larger grid project Stockholms Ström, which will provide an entirely new structure for the electrical grid in the growing Stockholm region. The project is scheduled to be commissioned by end 2016.
The HVAC 220 kV cable system contains five circuits with single-core cables with a total length of 21 km, which will have the capacity to transmit power across the bay between the areas of Kevinge and Bergshamra, a distance of 1.25 km. By connecting the submarine cable to existing underground cables, energy will be transmitted below ground and under water, replacing overhead lines in the region and reclaiming valuable land.
"As the Stockholm region grows, the demand for more efficient power transmission and utilization of land increases. This submarine cable system will support the new electrical grid structure being established enhance reliability of power supplies" said Patrick Fragman, head of ABB's Grid Systems business, a part of the company's Power Systems division. The Edsviken project is the sixth high-voltage cable system that Svenska kraftnät has awarded to ABB during the past six years.
