In 2005, the largest photovoltaic (PV) plant in the metropolitan region of Hamburg was put into operation on a former waste disposal site in Neu Wulmstorf. The plant, with an output of 500 kWp, sufficient to meet the electricity requirements of 120 households, was realised in only three months. A total of 3,132 polycrystalline solar modules lean towards the sun, with the long rows of modules designed to blend aesthetically into the hilly landscape. Attached to concrete foundations are steel mountings which position the modules at an angle of 30° to the sun. In addition to the solar power plant, three wind turbines and a combined heat and power plant, run on landfill gas, generate enough power for 1,600 households.
