Sweden, Stockholm/Switzerland, Zürich: Hitachi Energy’s power quality solutions will improve transmission capacity and voltage stability in the power grid.
Hitachi Energy and its consortium partner Kanonaden Entreprenad Mälardalen AB have announced another major order from Svenska kraftnät for a power quality solution to enable improved transmission capacity on the existing 400 kV transmission line, CL26. Two new 400 kV series compensation systems will be built to replace the existing obsolete system in Tandö. The new stations will be in Olingan in Härjedalen municipality and Gräsmark in Sunne municipality.
The new series compensation systems should reduce downtime and environmental impact by increasing transmission capacity and improving voltage stability in the network. The companies will provide a complete technical solution, from design and project management to delivery, installation, and commissioning. The new stations are expected to start operation in April 2026.
“We are very grateful and proud to be trusted again by Svenska kraftnät to deliver our expertise in Sweden,” says Tobias Hansson, Country Managing Director of Hitachi Energy in Sweden.
According to Hitachi Energy’s statement, it is possible to increase the transmitted power by up to 50% through new and existing power lines by installing a series of compensation systems at one or more suitable points in a power grid. From an electrical point of view, a series-compensated power line will reduce the length of the line and improve the voltage stability in a power grid.
