The scope of supply for the Bison 1B wind power plant includes the transportation, erection and commissioning of the 15 direct drive wind turbines. The 16 SWT-2.3-101 wind turbines at Bison 1A are presently being installed and the 15 SWT-3.0-101 direct drive wind turbines for Bison 1B will be delivered in August 2011.
