ALLETE Plans Expansion of North Dakota Wind Facility

By Editors of Power Engineering

ALLETE Clean Energy announced it will expand the Thunder Spirit wind facility in North Dakota to 150 MW.

The expansion was sparked by a 25-year power purchase agreement with Montana-Dakota Utilities. MDU also has the option to purchase the expansion when it is complete as it did with the first phase of Thunder Spirit.

The new phase will include 13 to 16 turbines, and is estimated to begin construction in May 2018. Thunder Spirit currently has a capacity of 107.5 MW.

“We are pleased MDU has selected us to expand the Thunder Spirit Wind project and look forward to partnering with them, area landowners and Adams County officials as well as North Dakota regulators on this exciting project that will deliver additional carbon-free energy to serve its customers,” said Allan S. Rudeck Jr., president of ALLETE Clean Energy. “This transaction strengthens ALLETE Clean Energy’s renewable energy repertoire and is consistent with ACE’s multipronged growth strategy to expand its clean energy project portfolio by pursuing acquisitions and new builds with long-term power sales agreements, build-transfers and renewal investments of existing facilities.”

ALLETE, established in 2011, also owns and operates wind facilities in Minnesota, Iowa, Oregon and Pennsylvania.
