Herrenwyk power station was a coal-fired power station in Lübeck-Herrenwyk, Germany. It was the first regional power station in Schleswig-Holstein. The power station was owned and operated by Nordwestdeutsche Kraftwerke Aktiengesellschaft (now part of E.ON). Construction of the power station started in 1910 and the power station was commissioned on 11 June 1911. In 1955, a new 25 megawatt (MW) unit was commissioned. In 1992, the Lübeck-Herrenwyk power station was demolished after the bankruptcy and demolition of a local metallurgical plant.
