Nuclear power plants generate vast amounts of base-load electricity. Around the clock. They are particularly important for Switzerland in the winter, when domestic hydropower plants do not generate sufficient electricity and the European countries have an increased demand for electricity. In Switzerland alone, 40 percent of the generated electricity comes from nuclear power plants. Alpiq itself does not operate any nuclear power plants, but holds a stake in the two nuclear power plants Gösgen (40 %) and Leibstadt (32.4 %). Alpiq also has a 33 % share in Kernkraftwerk-Beteiligungsgesellschaft AG (KBG), which owns energy drawing rights from the EDF French nuclear fleet.
