General Electric Co. announced that it received a contract from German project developer Energiekontor AG to supply 41 turbines for four wind power projects.

Financial terms were not disclosed.

GE said the turbines use a special 165-foot blade to help capture more energy and improve efficiency.

The new units will generate 250 million kilowatts of electricity a year, which is enough to supply more than 70,000 German households, GE said.

All 41 wind turbines, which will feature a 323-foot tower and a rotor diameter of 338 feet, will be manufactured in Germany and commissioned next year.

Energiekontor also signed a service agreement with GE that covers spare parts, maintenance, routine inspections and remote monitoring, GE said.
