Evaluating Hydro Project Benefits with the POWRSYM Production Cost Model
The contribution that a hydro peaking project or pumped-storage project makes to reducing system operating costs can be determined only by modeling the project's operation...

Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...

Columbia River System Operation Review
For many years hydroelectric power has been a surplus commodity in the Pacific Northwest. However, this picture has been changing rapidly in recent years. Increasing pressures for use...

An Improved Incremental Economic Dispatch Method for Hydroelectric Generators with Nonconvex Energy Production Cost Curves
The Bureau of Reclamation (Reclamation) has undertaken a program to improve water resource management at its hydroelectric powerplants. One feature of the resource optimization program...

Development of the Collett Reservoir Addition to the Muck Valley Hydroelectric Project
The existing 26 MW Muck Valley Hydroelectric Project is located on the Pit River, 90 miles east of Redding in Northastern California. The Project was licensed by the Federal Energy Regulatory...

Engineering Risk Assessment for Hydro Facilities
Faced with escalating property insurance premiums, the Alaska Energy Authority decided to evaluate what losses may realistically be expected due to catastrophic events at their hydroelectric...

The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...

Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...

Dam Stabilization/Modification at Lighthouse Hill and Schuylerville Hydropower Developments
Remedial measures including posttensioning of concrete structures, earth dike armoring, tainter gate modification and replacement of deteriorated concrete to meet federal and state hydraulic...

Dam Safety Rehabilitation of the T.V.A. Nickajack Hydroelectric Project
Safety of its dams has always been of great concern to the Tennessee Valley Authority (TVA). The agency has throughout its history enforced conservative designs, good construction practices,...

The Replacement of Penstocks at TVA Ocoee II Power Plant
The Tennessee Valley Authority (TVA) replaced the steel penstocks at its Ocoee II power plant near Ocoee, Tennessee. A total replacement was necessary because of severe corrosion on the...

Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...

Civil Design of the Sidney A. Murray Jr. Hydroelectric Station
This paper addresses the general civil design of the Sidney A Murry Jr Hydroelectric Station with special emphasis on the design requirements of the project's unconventional...

Superplasticized Concrete for a Prefabricated Powerplant Structure
This paper describes the use of superplasticized concrete in extremely difficult placements inside a restricted access preassembled powerplant structure (PPS) of a 192 MW Sidney A Murray...

Evaluating History?The Edison Sault Powerhouse
The hydroelectric facility owned by the Edison Sault Electric Company at Sault Ste Marie, Michigan was an engineering marvel when it was designed and constructed. This paper explores the...

Design of Penstocks in Severe Earth Slide Locations
This paper deals with the problems of locating a penstock for a small hydroelectric plant at a site in Northern California that experiences considerable land movement during the rainy...

Penstock Rehabilitation
The deterioration of aging penstocks is a common problem at many existing hydroelectric plants. A comprehensive understanding of the physical condition and functional limitations of an...

Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...

Rocky Mountain Project?Overview
The Rocky Mountain Project, in Northwest Georgia, will be a three unit hydroelectric pumped-storage project with 850,000 kW installed in an above ground powerhouse. The gross water volumes...

A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....
