Butte, Mont. – Dec. 15, 2022 – NorthWestern Energy’s Board of Directors announced that Mystic Lake Dam, about 75 miles southwest of Billings, Montana, is renamed Rowe Dam at Mystic Lake in honor of the dedicated service of CEO Bob Rowe, who is retiring this month.

Rowe joined NorthWestern Energy as president and CEO Aug. 13, 2008.

“Bob has been an extraordinary leader and his valuable contributions to the company, the communities we serve and the energy industry will be remembered always and will provide benefits for years to come,” said NorthWestern Energy President and COO Brian Bird. “Bob led NorthWestern Energy’s successful acquisition of 11 dams in Montana in 2014, with the carbon-free energy generated from these hydroelectric facilities dedicated to serving our Montana customers.

“Today 59% of the energy NorthWestern Energy serves our Montana customers with is from carbon-free - hydro, wind and solar - generation.”

Rowe Dam at Mystic Lake, NorthWestern Energy’s only storage hydro facility, began generating electricity in March 1925. The foot trail near the powerhouse offers a popular path to Mystic Lake and the high country of the Absaroka-Beartooth Wilderness.
