Fergus Falls, Minnesota, January 4, 2023: Yesterday Otter Tail Power Company closed on the purchase of Ashtabula III Wind Energy Center. The 39-turbine site in Barnes County, North Dakota, delivers a total combined capacity of 62 megawatts, harnessing some of the nation’s best wind resources to generate clean, cost-effective energy.

Ashtabula III began commercial operation in 2010. In 2013 Otter Tail Power began purchasing electricity from the wind farm through a purchase power agreement. “Our customers have benefited from wind resources since 2002,” said Otter Tail Power President Tim Rogelstad. “Purchasing Ashtabula III is part of our least-cost plan to meet our customers’ energy needs, both now and in the future.”

The company projects that by 2025 its owned and contracted energy generation will be more than 50 percent renewable.
