Plant operators are responsible for the operation of up to four generation plants at one time via remote control operations. Glennallen diesel, Valdez diesel, or the cogeneration plant, as well as the hydro project. Hydro plant tours are available. Contact Colleen Granger to arrange a tour . The transmission line provides the link to all four generating plants.
Power can flow from any of the generating facilities to where the power is needed.
Historically, power flows from the Solomon Gulch hydro plant to the Copper Basin district during the summer months, and flows from the Glennallen Diesel plant to the Valdez district during the winter months. The transmission line traverses severe terrain between the two districts and parts of it, in the Thompson Pass area, are in potential avalanche danger. Most recently, the transmission line was hit by an avalanche in January 2000.
