Electricity is always flowing and the energy sector is always active – 24/7, 365 days a year. New grid projects, exciting facts about electricity, digitalisation, innovations, the environment – we regularly publish informative articles on a wide range of topics. Always up-to-date, always with our finger on the pulse. Welcome to our blog!
The old extra-high-voltage grid in Goms is being dismantled; a move that will significantly improve the natural scenery on the valley floor. An interview with Gerhard Kiechler, the Mayor of Goms (VS) about the power line and energy-rich Goms.
Powerline construction: Various factors influence de costs
Electricity is an omnipresent part of our life that we often take for granted. Without it, our social and economic life would cease to function. As the backbone of the Swiss electricity supply, the transmission grid plays a critical role in ensuring the security of supply.
Renewable energies play an important role in establishing a climate-neutral supply of energy. However, integrating these power sources into the supply of electricity presents a number of challenges.
The renovation of the Mühleberg substation included replacing outdoor switching substations with an indoor switching substation. This made it possible to renaturalise an area the size of four football fields, which is to say, convert it back to a habitat for plants and animals.
Although the water supply is of national importance, it is usually the responsibility of the municipalities. Greater integration would allow better security of supply and quality assurance.
To ensure the security of supply in the canton of Grisons and the transportation of Engadine hydropower, Swissgrid is adding another «system» to the line.
The commissioning of a new extra-high-voltage line does not happen every day. And the commissioning of the new 380 kV line between Beznau and Mettlen on 19 May was even more exceptional.
The construction of the new 30-km-long extra-high voltage line in Goms is making great progress. On the section between Ernen and Ulrichen, electricity has been flowing at 380 kilovolts since October 2019. However, the work is not quite finished yet.
On 20 December, BKW will shut down the Mühleberg nuclear power plant. Forever. The power plant will be switched off and dismantled. This will result in the loss of around 370 megawatts in electricity production in the Bern region.
