  • Solar power plant above Klosters commences partial operation

    Solar power plant above Klosters commences partial operation

    The first 15 per cent of Madrisa Solar feeds electricity into the grid. According to a press release, the first 500 solar tables are fitted with 3,000 bifacial solar modules. The electricity will be used to power the neighbouring Klosters-Madrisa mountain railways.

    The solar power plant at 2,000 metres above Klosters Dorf is set to achieve an output of 11 megawatt peak when fully built on an area of 150,000 square metres with around 20,000 solar modules. Of the 17 gigawatt hours of electricity, 40 per cent will be generated in the winter months between October and March. Commissioning of the entire plant is scheduled for autumn 2027. By autumn 2026, 50 to 60 percent of the output should already be available.

    Madrisa Solar AG is a joint venture between Repower, EKZ and the municipality of Klosters, each of which holds a one-third stake. Madrisa Solar is the first solar power plant of the national solar express to feed electricity into the grid.

  • High-temperature solar power plants for continuous energy supply

    High-temperature solar power plants for continuous energy supply

    The centrepiece of 247Solar’s technology is a high-temperature heat exchanger developed by David Gordon Wilson, Professor Emeritus at MIT. By integrating this heat exchanger into a conventional turbine similar to a jet engine, efficient and emission-free energy generation becomes possible. The turbine utilises hot air, which is heated to around 1,000 degrees Celsius by solar energy, to produce both electricity and heat.

    Solar power plant with integrated energy storage
    An innovative component of this system is combined heat and power generation, supplemented by thermal energy storage. These store heat in solid materials, which can then drive the turbine when solar radiation is not available. This enables a continuous energy supply, regardless of the time of day and weather conditions. The generation capacity of the model presented is 400 kilowatts of electricity and 600 kilowatts of heat.

    The modular design of the system offers a wide range of possible applications, especially for remote or self-sufficient communities. This technology is ideal for combining with other renewable energy sources such as wind power to provide a holistic and sustainable energy supply.

    Bruce Anderson, Managing Director of 247Solar, emphasises that the main aim of developing this system was to overcome the intermittency issues of conventional renewables. The ability to provide uninterrupted energy represents a significant advance in the utilisation of renewable energy sources and could play a key role in the global energy future.
