Located on the banks of the Elbe River,
the Stade nuclear power station was commissioned
in 1972. It has been cogenerating
process heat for a neighboring salt
works since 1984.
The Stade plant is two-thirds owned
by E.ON Kernkraft GmbH. The remaining
one-third stake is owned by Vattenfall
Europe AG.
