Aargau Updates Energy Strategy to Allow New Nuclear Power Plants

Aargau's government has revised its energy strategy to permit new nuclear power plants, following the Ständerat's approval. The aim is to produce more CO₂-low electricity, with a target to double the annual output from such sources by 2035. The Aargau parliament, dominated by a conservative majority, voted in favor of this strategy. The region currently produces around 15 terawatt-hours of electricity, primarily from nuclear sources. New nuclear plants could be necessary as existing facilities are set to shut down by 2032.

Currently, Aargau produces about 15 terawatt-hours of electricity, mainly from existing nuclear plants, Beznau 1, Beznau 2, and Leibstadt. The new strategy will replace the previous goal of increasing renewable energy to 6 terawatt-hours by 2036. The conservative majority in the parliament passed the strategy, recognizing increasing power demands for transportation and data centers, while the construction of new nuclear facilities is projected to remain unlikely before 2050 due to existing laws and financial uncertainties.
