The Impact of Drought on Hydropower Generation-Case Study of Bureau of Reclamation Hydropower Plant
The paper explores the effects of extended drought on power generation at Shasta hydropower plant, a Bureau of Reclamation facility in Northern California. Statistical measures of water...
Small and Low Head Pumped Storage Projects
With the recent completion of several very large pumped storage projects, the perception of a hydroelectric pumped storage project in some power industry circles may be that of a project...
Benefits and Applications of Modular Hydroelectric Pumped Storage
Hydroelectric pumped storage is the only proven and most efficient technology available for energy storage. It is used by utilities to provide peak and intermediate power and to optimize...
Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...
Lake Siskiyou Power Project
The Lake Siskiyou Power Project was constructed at the foot of the existing Box Canyon Dam on the Sacramento River in Northern California. Major project features included the construction...
Net and Hydroacoustic Monitoring of Fish Passage
In 1986 EPRI published a review of available fish protection technologies for use at hydroelectric facilities. One major conclusion of that study was that fish protection systems were...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
Deflector Synchronizing and Governing
This paper is a survey of deflector control speed govern impulse turbines for synchronization to a grid, and for isolated operation. There are several advantages to deflector control versus...
Optimising Electric Power From a Small Scale Hydro Plant
The paper summarizes new development in electrical power generation from small scale hydro prime movers. It describes various methods of power generation such as CSCF (Constant speed constant...
Standard Safety and Control Concept for Double Regulated Small and Medium Hydro Turbines
The paper proposes a standard control concept for double regulated small and medium hydro turbines. The concept is based on minimum protection requirements for safe and reliable quick...
Measurements of Time Lag in Concrete Gravity Dam Foundations
Uplift measurements from eight large concrete gravity dams show that the time lag between an increase in headwater level and a corresponding increase in uplift pressure is insignificant....
Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...
Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
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...
Estimating Uplift in Cracks in Concrete Dams
Results are presented of a three year research program on the modeling of uplift pressures in cracks in concrete gravity dams, and the effectiveness of drains in reducing those pressures....
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...
Analysis and Stabilization of Ambursen Dams?Two Case Studies
Case studies are presented about the analysis and rehabilitation of two slab-and-buttress (Ambursen) dams. The paper discusses the investigation techniques used, including sampling of...
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...
