Alpine solar projects in Switzerland, such as the one in Klosters, face significantly higher costs than anticipated, which may hinder the Solarexpress initiative aimed at providing additional winter electricity. With the Klosters facility projected to cost nearly 70 million francs, concerns are rising about the economic viability of these projects. Despite generous government subsidies covering up to 60% of costs, energy companies report that securing buyers for this expensive solar power is critical for construction to proceed. Experts call for sustainable long-term funding solutions for these renewable energy ventures.
