Renewable energies remain on course for growth despite difficult market conditions
The electricity producer aventron produced around 15 per cent less renewable electricity in the 2025 financial year than in the previous year. Nevertheless, the company reported solid financial figures with net revenue of CHF 120.5 million and a net profit for the year of CHF 10.3 million.
Aventron has announced its key financial figures for the 2025 financial year. In total, the producer of electricity from renewable energies generated around 1.3 billion kilowatt hours of electricity – around 15 per cent less than in the previous year (2024: 1.498 billion kilowatt hours). Aventron cites historically weak weather conditions and high price volatility, including negative electricity prices, as the reasons for this.
Despite the decline in production, the result remains “solid” according to a statement. Net revenue amounted to 120.5 million Swiss francs (2024: 134.9 million Swiss francs), while the EBIT margin (earnings before interest and taxes) was around 21 per cent. Net profit after taxes reached CHF 10.3 million.
In 2025, aventron continued its diversification strategy with solar, wind and hydro technologies and further developed its portfolio. In Switzerland, construction began on the Sedrun Solar (Grisons) and APV Sidenplangg (Uri) alpine photovoltaic projects. In Italy, realisation of the 25-megawatt Lazio 01 solar power plant began, while two wind farms are under construction in France and Germany. The company invested a total of CHF 67 million. At the end of the year, the portfolio comprised a consolidated total output of 819 megawatts (previous year: 797 MW) in operation or under construction.
In the medium term, aventron intends to focus increasingly on successful electricity marketing and the expansion of data management and monitoring systems. The aim remains to build up a portfolio with a total output of 1000 megawatts. The Münchenstein-based company operates and develops power plants in the areas of hydro, solar and wind energy in Switzerland and selected European countries.
