Swiss Region Rejects Plan for Solar Parks on Alpine Mountainsides

Geneva, Switzerland (Natural energy News): In a pivotal referendum, voters in the Valais canton of southern Switzerland have voiced their opposition to a proposal that would have allowed the construction of large solar parks on the picturesque Alpine mountainsides. The rejection is a significant setback for the federal government's ambitious agenda to expand renewable energy sources in the country.

The referendum, which took place against the backdrop of growing concerns about climate change and its environmental impact, saw 53.94% of voters rejecting the proposal, with a voter turnout of 35.72%. This decision underscores the intricate balance between economic interests and environmental conservation in the region.

The opposition to the plan transcended typical political boundaries and brought together diverse groups, including environmentalists and conservative populist parties, in an unusual coalition. Critics of the proposal argued that installing solar parks on pristine Swiss mountains would mar the natural beauty of the landscape and preferred a more localized approach, such as outfitting buildings and homes in towns and cities with solar panels.


Valais, known for its abundant sunshine, had been considered a prime location for solar park development in Switzerland, particularly during the winter months when the country requires electricity imports due to reduced hydropower generation. Proponents of the plan contended that high-altitude solar parks, above the typical cloud cover, could provide a reliable and renewable energy source during this period. Moreover, federal funding for such projects, up to 60% of financing, could have accelerated solar power development.

The rejection of the proposal does not entirely rule out the possibility of solar parks in the region if the private sector decides to pursue them. However, it does hinder Valais in its competition with other regions like central Bern Oberland and eastern Graub√ľnden, which are vying for federal funding to support similar projects.


Switzerland has set ambitious targets for solar energy development, aiming for 2 billion GWh of new solar energy under legislation passed in September 2022. Notably, some areas, such as nature reserves, are exempt from potential solar development. In line with its commitment to combat climate change, Swiss lawmakers have also approved a plan to achieve "net-zero" emissions by 2050 and have allocated significant funds to transition companies and homeowners away from fossil fuels.

The referendum's outcome reflects the delicate balance that many regions around the world face as they seek to expand renewable energy sources while preserving the natural beauty of their landscapes. It also highlights the importance of considering local concerns and environmental impact when pursuing large-scale energy projects.
