OKG's three reactors
OKG owns and operates three boiling water reactors (BWR), Oskarhamns 1, 2 and 3, which are often referred to as O1, O2 and O3. The reactors began commercial operation in 1972, 1974 and 1985, respectively.
At an extraordinary shareholders' meeting held in October 2015, OKG's majority owner upheld their policy decision on the premature shutdown of units O1 and O2. The decision entails that there will be no future investments at unit O2 and the reactor will not be restarted. On 17 June 2017, unit O1 delivered its final kilowatt hours of electricity.
Unit O3 is one of the largest nuclear power plants of its kind with a gross capacity of 1,450 megawatt. Unit O3 annually deliver energy to such an extent that it equals the annual consumption of approximately half a million homes.
