The maximum national capacity of 12,696 MW can be utilised.

Germany took the axe to the bulk of its nuclear capacity in the summer of 2011, switching off the seven oldest blocks plus Vattenfall's Kruemmel permanently after the Japan nuclear crisis earlier that year raised safety concerns.

German policymakers agreed to leave the 8,821 MW represented by the eight blocks offline when a three-month moratorium expired at the end of June 2011.

Before the Fukushima crisis, German (gross) nuclear capacity had amounted to 21,500 MW.

The policy switch in 2011 reversed longer nuclear life cycles that had been granted to the remaining nuclear power stations in the autumn of 2010. It also sped up the timetable for closure of all remaining capacity by 2022.
