Wind and solar power ensure a stable electricity supply in the regional energy system
In 2025, the Swiss Energypark generated a total of 134 gigawatt hours of electricity. This represents 81 per cent of regional demand. While wind and hydroelectric power generation fell sharply, solar power generation rose significantly.
According to a statement from the operator BKW, the Swiss Energypark in the supply area of the Société des Forces électriques de La Goule generated a total of 134.45 gigawatt-hours of electricity in 2025. This represents 81 per cent of the region’s total consumption of 166.96 gigawatt-hours. In the previous year, the Energypark had generated 139.6 gigawatt hours.
Wind energy once again contributed the largest share to electricity production, with a total of 86.50 gigawatt hours. The Juvent wind farm alone generated 72.6 gigawatt hours. Although this is less than the 91.1 gigawatt hours of the strong previous year due to low wind speeds, wind energy remains a reliable source of electricity, particularly during the winter months.
The La Goule hydroelectric power station supplied 16.29 gigawatt hours, its worst result in decades. In the previous year, the figure had been 17.6 gigawatt hours.
Solar energy, by contrast, grew significantly. In 2025, it supplied a total of 31.66 gigawatt hours, accounting for 24 per cent of total production. In the poor year of 2024, the figure had been just 13.6 gigawatt hours.
The Swiss Energypark covers an area of 251 square kilometres between the cantons of Bern and Jura. 21,000 people live here.
