Presentation Description

100 Years and Counting, Two Mining-Related Hydroelectric Projects That Continue to Generate Power Long After Mining Is Over

In 1915, engineers charged with generating 10,000 horsepower to run the large mining and milling facilities in Southeast Alaska designed and built two hydroelectric projects in the Juneau-Douglas area. The Salmon Creek Dam Project required state-of-the-art engineering in terms of innovative concrete dam design and the Annex Lake Project relied on precision underground engineering to install a lake tap that did not drain the natural lake. Both projects delivered reliable power throughout the planned operating period between 1915 and 1941. When mining stopped, the hydroelectric projects remained operational and delivered power to the local community. Today, the Salmon Creek and Annex Lake projects provide up to 15% of the electrical power demand for the same community. The story of how this mining infrastructure transitioned from the mining period to an electrical utility in the 21st century offers insight into the design criteria for the operating life of a facility and the unique role of utility-related regulations.
