Madrisa Makes History as First Alpine Solar Plant

Switzerland has achieved a significant milestone in its renewable energy transition with the Madrisa Solar plant becoming the country's first high-altitude solar power facility to feed electricity into the grid. Located in the picturesque canton of Graubünden above Klosters, this groundbreaking project represents a new chapter in Swiss alpine energy production. The project is a collaborative venture between Repower, Elektrizitätswerke des Kantons Zürich (EKZ), and the municipality of Klosters, with each entity holding an equal stake in the initiative.

Situated at an impressive altitude of 2,000 meters above sea level, the Madrisa Solar plant is specifically designed for optimal winter power generation. The facility currently features 500 ground-anchored solar panels and 3,000 solar modules. Upon completion, the plant is projected to generate 17 GWh of electricity annually, with over 40% of this production occurring during the crucial winter months. This seasonal output capability addresses one of Switzerland's key energy challenges - maintaining stable power supply during winter periods.

The implementation of the Madrisa Solar project represents a significant investment of CHF70 million. Currently operating at 15% of its planned capacity, the facility is already contributing to the local power grid. The project is being executed under the federal government's Solarexpress programme, with full commissioning scheduled for completion by the end of 2027. The electricity generated is being utilized both by EKZ and locally for powering the Klosters-Madrisa mountain railway, demonstrating effective integration with existing infrastructure.

The Madrisa Solar project represents a significant step forward in Switzerland's renewable energy strategy. The substantial investment of CHF70 million demonstrates the country's commitment to sustainable energy solutions. The plant's ability to generate 40% of its annual output during winter months addresses crucial seasonal energy demands, potentially reducing dependence on imported electricity during critical periods. The project also serves as a model for sustainable alpine development, showing how renewable energy infrastructure can be integrated into mountain environments.

The success of Madrisa Solar is paving the way for similar projects in the Swiss Alps. Two other major alpine solar plants are currently under construction in Graubünden: NalpSolar by Axpo and SedrunSolar by Energia Alpina, both located in the municipality of Tujetsch in the Surselva region. This expansion of high-altitude solar power generation could significantly reshape Switzerland's renewable energy landscape, potentially establishing a new standard for alpine nations seeking to diversify their energy sources while maintaining environmental responsibility.
