Wind energy planning and operator company Neue Energie Verbund AG (Nevag) is one of three companies to be chosen by Greenpeace Germany to supply power to its Hamburg headquarters in a trial project which could later be extended to 60,000 households. Starting this month, Greenpeace will stop receiving power from utility HEW, which generates 80% of its electricity from nuclear sources, and switch to green power trader Ökostrom Handel, based in Hamburg. Other supply will come from municipal utility Stadtwerke Schwabisch Hall, which generates power in gas fired combined heat and power plant, and Nevag, which operates about 80 MW of wind power stations. Greenpeace has searched for power suppliers which pledge that none of their electricity is generated from coal or nuclear power stations. The winning companies have promised to build new renewables plant over the next two years. If all goes as planned, then the 60,000 households who responded to Greenpeace's "Change your supplier" program earlier this year will be sent an offer to switch their electricity source from start 2000.
