The growing volume of wind energy capacity in northern Germany is influencing decisions on construction of new conventional power stations. Municipal utility Stadtwerke Hanover has announced plans to participate in a 1100 MW coal power station project in partnership with energy giant E.ON Kraftwerke. Initially, Stadtwerke had favoured the site of its existing coal station at Mehrum near Hanover as the location for the new plant, due for commissioning in 2015. "But a closer analysis revealed several disadvantages such as restrictions on load due to the planned expansion of wind energy in northern Germany." The existing 690 MW Mehrum station is already used to supply reserve capacity, predominantly for wind energy.
