Nuclear power plants have been in operation in Switzerland for over 50 years and currently generate one third of the country's electricity - reliably, resource-efficiently and with low emissions. The two reactor units (KKB1, KKB2) of the Beznau nuclear power plant (KKB) have been in operation since 1969 and 1971 respectively. In 1979, the Gösgen nuclear power plant (KKG) in Niederamt district of Solothurn was connected to the grid, followed in 1984 by the Leibstadt nuclear power plant (KKL). The Mühleberg nuclear power plant, which had been in operation since 1972, was shut down in 2019 and has been undergoing dismantling since then.

Production, availability and trends of nuclear power plants

Net production and heat extraction

KKB provides heat for the Lower Aare Valley Regional District Heating scheme (Refuna). KKG supplies process heat to two industrial plants located in the vicinity of the facility.

Annual availability

The nuclear power plants carry out an annual main inspection each year, coordinating with one another in this regard. Maintenance work usually takes four weeks per plant and is conducted during the summer months.

Q&A

KKB supplies heat to more than 2,600 connections in the industrial, commercial, public and domestic sectors via the "Refuna" district heating network. Around 4,000 households, with just under 15,000 residents, benefit from the heat extracted by KKB.
