Acquisition of Switzerland’s largest photovoltaic plant

aventron, UBS Clean Energy Infrastructure Switzerland and Swiss Solar City have together acquired the largest photovoltaic plant in Switzerland. The solar power plant with installed capacity of 8.3 megawatts located along Lake Neuchâtel has proved its potential this summer

The warehouses of Philipp Morris in the municipality of Onnens by Lake Neuchâtel are vast. The main building alone has a roof 450 metres in length, on which 35,000 state-of-the-art solar panels are installed. The photovoltaic plant has an area of 49,000 m2 – the equivalent of seven football pitches. The installed capacity is 8.3 megawatts. This makes it Switzerland’s largest solar power plant to date. Annual production is around 8 million kilowatt hours of solar power, which – in terms of figures alone – is enough to power around 2,000 households.

The solar power plant was developed and built by solar specialists Soleol SA from Estavayer-le-Lac. Now, the plant, in operation since December 2016, was jointly acquired by aventron and UBS Clean Energy Infrastructure Switzerland, through their joint subsidiary Birseck Solar, and by Swiss Solar City. In a process spanning many months, the three partners checked and evaluated the high-performance photovoltaic plant and structured the joint acquisition under the guidance of aventron. Through this acquisition, aventron is expanding its portfolio of Swiss photovoltaic plants, bringing it up to 28 megawatt peaks (MWp), and cementing its position as one of the largest solar power plant operators in Switzerland.
