The new extra-high-voltage line will be built on the shaded southern slope further away from the settlement areas. The western part will be constructed at a height of 600 metres to 1,400 metres above sea level, while the eastern part will be up to 1,200 metres above sea level. The line avoids higher, exposed areas. It crosses numerous valleys and trenches, such as the Illgraben, the Nanztal and Vispertal valleys as well as the Saltinaschlucht gorge. Additional visual impact arises in the municipality of Turtmann as well as at the Visp/Stalden valley crossing.
The dismantling of the existing line will relieve the burden significantly on settled areas and leisure facilities. This line runs through the centre of the villages in the Niedergampel, Gampel, Raron and Baltschieder region and hinders their settlement development. In Visp, the settlement area on the western slope is bypassed, as well as in the south and on the eastern slope. The steep slope means that the new line will pass above the town and will be more visible from the surrounding hiking paths than from the town centre. South of Visp, the new line crosses the Vispertal valley near the new motorway bridge. This is particularly visible from Visperterminen.
The bundling of the new line with the existing 220-kilovolt Stalden – Visp – Mörel line provides additional relief for the area around Visp up to Bitsch. In Visp, the existing Stalden – Lalden line will be dismantled from the branch pylon in Lalden, via Lonza-Werke up to the intersection with the new 380-kilovolt line.
The line crosses the protected Pfyn forest nature park shortly after the Chippis substation. The line route therefore leads along the base of the slope to ensure that it has as little impact as possible. In the Pfyn forest, the two Chippis – Mörel and Chippis – Stalden lines will be bundled along the same route. In addition, lines with lower voltage levels will be laid underground or bundled. The burden on this unique pine forest will be massively reduced compared to the current situation.
The burden on the population will be reduced by the greater distance of the line to the settlements. The limit of 1 μT for electromagnetic radiation will be complied with across the board, with some areas reporting values well below this limit. The noise burden will be significantly reduced thanks to the use of the latest technologies and triple conductors.
