The contract, which was awarded by Minnesota Power, was originally for 33 SWT 2.3 101 turbines. This number has now been reduced to 16 in order to accommodate the 15 3MW machines.
The 2.3MW turbines are currently being installed at the project while the 3MW turbines are expected to be delivered by August next year.
Siemens launched the SWT-3.0-101, at the European Wind Energy Conference this April.
The new turbine, which has a 3MW capacity, will principally be available for onshore wind farms. Siemens claims it has a lower weight and half the parts of one of its 2.3MW products.
It uses a gearless drive train design with a permanent magnet generator.
