Fuel sources

This graph represents the various fuel sources (owned and purchased) that Otter Tail Power Company uses to serve its customers. Purchases from known fuel sources are reflected in their associated categories such as hydro, wind, etc. For example, the 6.06 percent hydro portion of our resource mix reflects approximately 1 percent from owned generation and approximately 5 percent from a purchased-power agreement.  All other purchases are reflected in the “Purchases from unknown fuel sources” category.

The Ashtabula Wind Center became operational in November 2008 and the Langdon Wind Energy Center in January 2008. We added the Luverne Wind Farm in September 2009. With these additions, the amount of wind-generated electricity our company owns or purchases is about 183 megawatts.
