Program: Lake Dorothy, Alaska, Hydroelectric Project
The Lake Dorothy Hydroelectric Project is being developed by the oldest utility company in the state of Alaska at a site located 17 air miles southeast of Juneau. The site is accessible only by helicopter, requiring all materials and equipment to be “slung” in, and the work crews to “commute” to work via helicopter. When the project is at complete power, the Lake Dorothy Hydroelectric Project will be the highest head hydro project in North America, with a lake elevation of 2440 ft and a powerhouse located at sea level. The project will generate 34.4 MW of electrical power to provide for the growing residential, business, and industrial needs of Alaska’s capital.
This presentation by
Mark Rohrbach will focus on the lake tap tunnel including access, rock quality and properties, advance rates, equipment, and logistics. Other aspects of the project, including the power station (and its excavation), the dam, the steel penstock, and the access road, will also be briefly covered.
