ALLETE Clean Energy, a wholly owned subsidiary of ALLETE announced that it has received the 45th set of new wind turbine blades from international blade manufacturer Tecsis for its refurbishment initiative at its Storm Lake and Lake Benton wind facilities in Iowa and Minnesota, respectively. ALLETE Clean Energy announced an USD 80 million project in August 2017 that includes replacing select blades, gearboxes and generators on turbines at the Lake Benton wind site in Lincoln County, Minnesota, and the Storm Lake I and II wind sites in Buena Vista and Cherokee counties, Iowa. The project will improve turbine performance and reliability, generate federal production tax credits at each site and support the renewal of power sale agreements at the Storm Lake sites.

Tecsis will provide more than 300 blades, utilizing the latest design and manufacturing technology to drive improved wind turbine generator performance.

Mr Bill Sawyer, general manager - operations at ALLETE Clean Energy said that "Tecsis provided a cost-effective, turnkey solution that has exceeded our expectations. Tecsis has demonstrated its ability to design, manufacture and deliver blades and manage the project that will position Storm Lake and Lake Benton to continue safe, reliable and increasingly efficient clean energy production for years to come."

The refurbishment is being staged from 2017 through 2020 to minimize turbine downtime and maximize safe energy production at each site. In total, the sites produce about 700,000 megawatt hours of energy per year, representing about 50 percent of ALLETE Clean Energy's current electricity sales. More than half of the sites' turbines have been refurbished, improving performance and qualifying them for federal production tax credits, supporting continued delivery of clean energy to utility customers across the upper Midwest.
