Probabilistic Analysis of Modernization Options
Benefit-cost analysis is a standard procedure for reaching planning decisions. Cost overruns and benefit shortfalls are also common occurrences. One reason for the difficulty of predicting...
Renovation and Uprating of Seven Hydropower Plants in Java
The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase...
A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....
Evaluating the Dynamic Operating Benefits of Hydro Power Plants
In 1986, the Electric Power Research Institute asked Decision Focus to develop a new planning model to quantify the dynamic operating benefits of power technologies that offer operating...
A Water Budget Approach to Instream Flow Maintenance
Storage reallocation is a current issue at many Federal water storage facilities that have hydroelectric generation. Allocation of storage to support instream flows is one of the changes...
Pumped Storage, the Environment and Mitigation
The privately financed 1,000 MW Rocky Point Pumped Storage Project located in central Colorado, USA, will be one of the world's highest head, 2,350 feet (716 m), reversible...
Distribution and Grain Sizes of Deposited Reservoir Sediments, Seventy Years after Dam Construction
The Elwha and Glines Canyon Hydroelectric Projects are located on the Elwha River in the northwest portion of the Olympic Peninsula in Washington State. The Elwha Dam was completed in...
Mercury in Fish and Water in New Impoundments?A Review of the Literature
Evidence to date indicates that only one metal, mercury, systematically bioaccumulates to ecologically significant concentrations as a direct result of impoundment. This bioaccumulation...
Reviewing the Role of Hydropower in TVA Reservoir Operations
The Tennessee Valley Authority (TVA) has reviewed the long term operating priorities for its reservoir system to determine the appropriate role of water quality and recreation as compared...
EPRI's Pumped Storage Planning and Evaluation Guide
EPRI's Pumped Storage Planning and Evaluation Guide was published in 1990. The Guide provides step-by-step procedures to: (a) evaluate pumped-storage operation in a utility...
The Mt. Hope Waterpower Project
The Mt. Hope Waterpower Project is a 2000 megawatt, underground pumped-storage hydroelectric power project located on the site of an inactive iron mine in the township of Rockaway, New...
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...
Technology Transfer for Small Hydro
The wide range of different definitions of what constitutes a small hydroelectric power plants is discussed and the conclusion is drawn that this definition should be based more on the...
A New Power Invention
Hydropower is the most natural form of energy generated in the World. It allows us to make use of our natural resources without pollution. It harnesses the basic fundamentals of nature...
Utilizing Wetlands for Stormwater Retention
The design steps an engineer uses to develop natural wetlands to provide flood control while continuing to retain their natural functions will be analyzed. This paper will include a discussion...
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...
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...
Evaluation of Rehabilitation Alternatives for Small Hydropower Plants
This paper describes methods for comparative evaluation of alternative rehabilitation measures for aging small-scale hydroelectric power plants located on storage reservoirs. The evaluation...
