Power Value Determinations
Past and current federal methodology and procedures in power value determinations are presented for consideration by Western Area Power Administration (Western), U. S. Department of Energy...

Economic Analysis of Low Head Hydropower Projects
A typical low head hydropower project is described and used as an example of the effect of tailwater on power generation. The discharge characteristics of upstream facilities, pool regulation...

Impact of Economic Factors on Development of the Lower Euphrates Basin in Turkey
The case of Lower Euphrates in Turkey represents fairly well the dynamic character of multi-purpose projects with respect to technological developments and changes in economic factors....

Economic Evaluation of Alternative Electric Power Developments
A hydroelectric-dominated power system and a thermal-dominated system represent different ways of meeting total electric demand, but with materially different cash flow patterns. This...

Need for Power Analysis: The Technical, Economic, and Financial Interrelationships
The Susitna Hydroelectric Project is one of the largest hydroelectric projects to be brought before the Federal Energy Regulatory Commission (FERC) by an applicant seeking the issuance...

New Concepts for Prelininary Hydropower Design
Hydropower generation on steep mountainous streams where storage is impractical can usually be made economical if: the flow duration curve shows sufficient energy available in the high...

Interchangeable Runners Can Increase Energy Output
Interchangeable turbine runners can be used to increase energy generation at some hydroelectric power sites. Two different turbine runners can be designed for different design heads or...

Rapid Filling of Reservoirs
The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels,...

Analysis of Expanding the Wolf Creek Powerplant
The Nashville District, Corps of Engineers, is examining the feasibility of expanding the Wolf Creek powerplant to increase its peaking capability. The economic analysis of peaking expansions...

Siphon Penstock?An Economic Way to Develop Hydros
As part of the 48 MW Jim Falls Hydro Redevelopment Project by Northern States Power Company, a minimum flow powerhouse was constructed with a siphon penstock. The Minimum Flow Unit (MFU)...

Uprating Hydro Turbines and Generators
Various engineering evaluations of the turbine and generator components are required when considering uprating units. Often, certain turbine and generator components have to be redesigned...

The Lowell Hydroelectric Project: A Case Study
The Lowell Hydroelectric Project, located on the Merrimack River in Lowell, Massachusetts, consists of an existing dam, canals, and turbine generating equipment presently operating at...

Small-Hydro Development and Public Decisionmaking
This paper is based on a larger study (Soden, 1985), and employs concepts distilled from public choice theory - an increasingly well-accepted approach to the study of public policy and...

The Global Outlook for Additional Hydropower Use
The present installed capacity of hydropower, worldwide, is nearly 400,000 megawatts which provides approximately 25 percent of the electricity generated. Extensive studies of the 86-Nation...

Increasing Hydropower Operating Efficiency
A method is described for determining the most efficient use of hydro units in a multiple unit hydro plant. In a multi-unit plant enough flexibility exists to load a chosen set of units...

Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...

The Impact of Proposed Federal Income Tax Changes on the Financing of Hydroelectric Projects
The paper presents an overview of the specific proposed changes that would have the greatest direct impact on the hydroelectric power industry. Next, it presents the major conclusions...

LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...

Wind Loads on Electrical Transmission Structures
Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....

A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
