In May 1969 the company RWE entrusted the firms KWU and Hochtief with building the first 1200 MWe stage of an electronuclear power station at Biblis. A second stage, almost identical to the first (1300 MWe) was ordered by RWE from the same firms in April 1971. Both stages are to be equipped with pressure-water reactors built to the Siemens formula. The installations are expected to come into operation in spring 1974 and autumn 1976.
