Presentations online: The prospects of undergrounding power lines - Lessons learned from pionieering cable projects
More than three years ago, we met in Switzerland to discuss the technical, environmental, financial and regulatory aspects of highest-voltage underground cables in Europe. Since then, a lot has happened in this field. At our workshop, which was kindly hosted by Amprion, we looked at the status quo of underground cables in Europe. Where are we, which lessons have we learned?
Cable Workshop - Understanding Underground Cables
The impact of overhead power lines is a key trigger for public opposition against grid extension projects. Often local pressure groups demand that a new line shall be put underground. Expectations into undergrounding are high while actual experience is comparatively low. In Europe, first projects include some kilometres of highest voltage underground cables, but the integration of innovative cable solutions into an aging power grid remains a challenge. As a consequence a lot of questions remain highly debated.
Understanding the Grid
Renewable energies are at the core of the social and political debates on the future of our energy supply system and current system security developments. How many new grid lines are necessary and why? What happens on windy days in the grid? How can system reliability be assured while integrating high shares of renewable energies? Will the new grid system be an extension of the actual or is it necessary to build a completely new one? What electricity transmission data can and should be disclosed to enable an integrative discussion on the future grid system?
