Resun

Resun AG (an acronym from the French REmplacement SUisse Nucléaire, Swiss nuclear replacement) was a company located in Aarau, Switzerland. Its purpose was to manage the construction of two new nuclear reactors. These are unofficially known as Beznau 3 and Mühleberg 2 from the locations where they should be built. In August 2017 the company was liquidated.

After 2020 the existing plants of Beznau (1969, 730 MW) and Mühleberg (1972, 355 MW) should cease activity. At the same time some import contracts with France for around 2000 MW will expire. With a combined electrical power output of 3200 MW, the new reactors would prevent the resulting energy gap and satisfy the expected domestic demand increase.
