Storfinnforsen – Midskog
The world’s oldest 400 kV line is being rebuilt
We plan to rebuild the line between Storfinnforsen and Midskog. It entered service in 1952 and now needs to be replaced with a modern line to be able to receive new wind power planned in the area.

About Storfinnforsen — Midskog
Svenska kraftnät is rebuilding the world's oldest 400-kilovolt line between Storfinnforsen and Midskog. This is because several wind power plants are to be built in the area around Sollefteå which requires a stronger national grid. With a modern line, we can take better care of the electricity produced.
The world's oldest line needs to be modernized
The line between Storfinnforsen and Midskog is the world's oldest 400 kV line. It entered service in 1952 and is one of many old national grid lines that need to be reviewed and rebuilt to meet society's electricity needs. By modernizing the line, we will achieve higher capacity, much better transmission capacity and less energy loss.
A modern line takes better advantage of the area's wind power
Several new wind power plants will be built in the area around Sollefteå. When wind power capacity increases more electricity will be produced and this will expose the area's electricity grid to larger loads. To manage this, the line between Storfinnforsen and Midskog is to be replaced by a new one with higher capacity. With a new line, we take better advantage of electricity from wind power. The electricity supply in the area becomes more reliable, efficient and environmentally friendly.
A new line will replace the old one between Storfinnforsen and Midskog
We plan to rebuild the line of about 62 km that currently runs between Storfinnforsen in Sollefteå municipality and Midskog in Ragunda municipality. The old line will be demolished and replaced by a new overhead AC line - the same technology used for practically the entire Swedish national grid. Apart from minor adjustments, we will build the new line along the same route as the old one.
The new line is estimated to be ready in 2021
Our work to rebuild the line is expected to begin in 2016 and be completed by 2021.
Facts
The line which today runs between Storfinnorsen in Sollefteå municipality and Midskog in Ragunda municipality is to be demolished and replaced by a new line on the route. Apart from minor exceptions, the new line is to be built in the same line corridor. Pylons on the line will mainly be placed in the same locations but with some adjustments.
Length: 62 km
Number of pylons: 217
Technology: 400 kV overhead AC line
