Minnesota Power has ordered 64 units of Siemens' latest 3 MW D3 platform wind turbines for the 205 MW Bison 4 wind project near New Salem, N.D.
The turbines feature a 113-meter rotor and 92.5-meter hub height. The blades will be manufactured at Siemens' facility in Fort Madison, Iowa, and the D3 nacelle component will be assembled in Hutchinson, Kan. Assembly of this specific component was recently moved from the company's nacelle facility in Brande, Denmark, to Hutchinson, Kan., further demonstrating the company's commitment to the U.S. wind industry, according to Siemens.
Installation is scheduled to begin in mid-June, and commercial operation is slated for December. The scope of supply includes transportation, installation and commissioning, as well as a three-year service and maintenance agreement.
The 205 MW Bison 4 addition will increase Minnesota Power's Bison Wind Energy Center's total output to nearly 500 MW. Siemens also supplied all of the wind turbines for the previous three phases of the center, which went into commercial operation in 2010 and 2012.
‘We're pleased to partner with a world leader like Siemens as wind energy production develops and matures,’ says Minnesota Power Chief Operating Officer Brad Oachs. ‘With the help of Siemens, we've integrated new direct drive technology into our Bison project while at the same time staying ahead of Minnesota's aggressive renewable energy standard.’
By 2025, utilities in Minnesota are required to supply 25 % of their power from renewables.
