One of the reactors at Ringhals nuclear power plant is operating at half capacity and the stoppage is now being extended by a week. The stoppage, which was first announced on Tuesday, was unplanned and is due to maintenance of a generator, according to a statement from the electricity exchange Nord Pool.
The loss of half the capacity at Ringhals 4 is expected to continue until 28 June.
The other reactor at Ringhals has also been shut down for its annual revision.
