Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part A: Failure Investigation and Lessons to be Learned
A lightning strike caused electrical failure at Spokane's two Upriver power plants, resulting in the river overtopping Project embankments, and causing nearly 11. 5 million...
Upriver Dam Hydroelectric Project Rehabilitation After Failure, Part B: Rehabilitation and Enhancement of Project Civil and Mechanical Facilities
A feasibility investigation of rehabilitation alternatives was conducted which identified several alternatives for repairing the damage and placing both powerhouses back on-line. These...
Rehabilitation of TVA's Great Falls Project
After seventy-one years of productive service, this two-unit, 31,860 kV plant is undergoing a major rehabilitation. The deterioration of the project has been of concern since the beginning...
No. 1 Water Wheel Project, Gilman, Vermont
This paper describes the replacement of an old generating unit with a new unit in a turn-of-the-century mill building where three other such units were already operating. The key issues...
Echo Dam Small Hydrodevelopment
In the mid 1970's, Bountiful City Light and Power began investigating alternative energy sources to furnish power to their distribution system. They engaged the firm of Bingham...
Design Improvements on a Small Hydro Project
The Whiskeytown Hydroelectric Project, built for the City of Redding, California, provides an excellent example of the type of improvements in general arrangement which can be achieved...
Hydropower Development at North Hartland Lake, Vermont
The purpose of this paper is to give a short history of the first hydropower development by non-Federal interests at a Corps of Engineers flood control dam and reservoir within the jurisdiction...
Small Hydrodevelopment: An Owners Perspective?El Vado, New Mexico Hydroelectric Project
The construction of the El Vado Hydroelectric Project posed several unique problems. The joint ownership of the dam between a Federal and State agency was unique to the region. The proposal...
Our Municipal Water System Has Power
Hydroelectric potential exists in the Boulder, Colorado municipal water system. Excess pressure is developed in the water system because the water originates in the Rocky Mountains, west...
Hydropower Goes Downtown
Beneath a busy street in Southern California seems an unlikely location for a small hydroelectric generating plant. However, located just below El Segundo Boulevard in the town of El Segundo...
Pyrites Hydroelectric Project, Canton, New York
