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 6.05 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 "Unknown purchases" category.

The new Langdon wind energy center came online January 12, 2008. With this addition, the renewable portion of our energy mix is projected to be approximately 13 percent in 2008.
