Heat and electricity supply No electricity shortage in Switzerland thanks to solar power
Due to prolonged drought conditions with minimal rainfall, river levels in Switzerland have dropped significantly, impacting hydroelectric power production. Rivers such as the Aare, Rhine, and Rhône are at historically low levels, leading to reduced electricity generation from run-of-river hydroelectric plants. Energy companies like Repower and Forces Motrices Valaisannes report production drops of up to 25% compared to historical averages due to lower water inflows. Despite these challenges, Switzerland has avoided a power shortage, partly because solar energy has compensated for the shortfall. Additionally, both nuclear power plants at Beznau I and II are currently offline, not due to water shortages but because of high water temperatures affecting cooling processes.
Switzerland has avoided a power shortage despite record-low river levels and the shutdown of two nuclear reactors, thanks largely to a surge in solar energy production. As of August 12, 2026, rivers such as the Aare, Rhine, and Rhône have reached their lowest recorded water levels, significantly reducing hydropower output. However, this decline has been offset by increased solar generation, preventing any electricity shortages. The prolonged dry spell with minimal rainfall has had a major impact on power generation. Run-of-river hydroelectric plants along these rivers are producing far less electricity compared to long-term averages. This situation mirrors other exceptionally dry years, such as 2003 and 2022, but the contrast is especially noticeable when compared to the high precipitation year of 2016. Energy providers have reported substantial declines in production. Repower, a supplier based in the canton of Grisons, stated that its hydropower plants produced approximately 25 percent less electricity between May and July due to low inflows. Similarly, Forces Motrices Valaisannes (FMV), a company in Valais, noted reduced snowmelt due to low winter precipitation, leading to lower power generation from run-of-river plants during the same period. Alpiq, an energy group based in Lausanne, confirmed similar issues at its facilities along the Aare River, reporting a 15 percent drop in water inflow compared to the long-term average. These reductions highlight the challenges faced by hydropower operators amid the current drought conditions. Despite the reduced hydropower output, Switzerland has managed to avoid a power crisis. Both nuclear reactors at Beznau I and II are currently offline, but this is not due to insufficient water supply. Instead, the shutdown is attributed to elevated water temperatures in the Aare River. The reactors require cooling water, which must not exceed certain temperature limits after the cooling process. With the Aare already warm, Axpo, the operator of the reactors, cannot release additional heated water into the river to protect aquatic life. This situation is primarily due to the high number of sunny days, which have boosted solar energy production. Unlike previous summers, solar installations have made a significant contribution to overall electricity generation this year. This increase can be traced back to the massive expansion of photovoltaic systems since the outbreak of the Ukraine war. According to the Federal Electricity Commission (Elcom), solar energy has acted as a crucial buffer against the adverse hydrological conditions in Switzerland. Without the extensive development of photovoltaics over recent years, the country's electricity balance would likely be more strained. Elcom emphasizes that this additional input has prevented potential shortages, allowing for continued stable power supply even under challenging circumstances. The role of solar energy in maintaining grid stability underscores its growing importance in Switzerland’s energy mix. As traditional sources face limitations due to environmental factors, renewable technologies like solar power are proving essential in ensuring reliable electricity provision.

The article discusses the impact of prolonged drought on hydroelectric power production in Switzerland, highlighting reduced water levels in major rivers like the Aare, Rhine, and Rhône. Despite this, there has been no electricity shortage due to increased solar energy generation. Energy companies such as Repower, Forces Motrices Valaisannes (FMV), and Alpiq report significant declines in hydropower output, ranging from 15% to 25% below average levels. The shutdown of nuclear reactors at Beznau I and II is attributed to high river temperatures affecting cooling processes rather than water scarcity. The piece emphasizes the role of solar energy in maintaining grid stability during the heatwave.
