SolarPeak Power: Managing Solar Energy Production in the AlpsDavid Bodor, Arno Amez-Droz, and Silas Zeller

Solar energy infrastructure has seen the most significant growth among all sustainable energy sources in Switzerland over the past decade. By 2050, Switzerland aims to generate 40% of its energy from solar power. To achieve this goal, numerous new large scale alpine solar projects are underway, with a notable spatial impact.

In the small municipality of Grengiols, with fewer than 500 residents, plans are underway for the largest alpine solar park in Switzerland. Although the project received a favorable vote, there are strong opposing voices, primarily concerned about the environmental and spatial impact on an otherwise pristine natural area.

A close examination of the Grengiols case study revealed three primary discussion points. The first aspect concerns organisation, including ownership percentages. The second aspect pertains to the chosen technology type and its specifications. The third aspect relates to the park’s location and its integration into the surrounding area.

To address the three discussion points of the Grengiols case study, these three distinct scenarios each target a specific issue. Alternative approaches in location, organisation and technology reveal further potential to support the local economy and minimize resistance amongst the people.
