Destruction of VOC's By Thermal Oxidation
The Clean Air Act Amendments of 1990 call for the regulation of 189 air toxics and requires control standard benchmarks of Maximum Achievable Control Technology (MACT). These emissions...
Biological Methods for Air Decontamination: Modeling Hydrocarbon Removal
Bench-scale tests indicate biofilter treatment of gasoline and diesel with activated carbon support media is first order, while removal of ethanol on compost is zero order. Treatment of...
Pumped Storage Promise
With many utilities facing potential shortfalls in generating capacity, pumped storage hydro plants could be a key to meeting peak-period energy demand in the 1990s. Pumped storage plants...
Evaluating Hydro Relicensing Alternatives?Impacts on Power and Non-Power Values
The relicensing of 300 hydroelectric plants in the next decade involves a total capacity of about 4,000 MW - a $10 billion value. A methodology recently developed by Decision Focus Incorporated...
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...
Extensive Civil Penalties Apply?Lessons Learned Since Waterpower '89
Section 12 of ECPA authorized the FERC to assess civil penalties in enforcing Part I of the Federal Power Act and its implementing regulations, as well as the terms and conditions of hydropower...
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...
Private Hydropower Projects: Exporting the American Experience
This paper addresses different aspects of exporting the American knowledge and experience in the private development of small-scale hydropower projects. It details the 'export'...
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...
Pressure-Time Flow Measurements Under Adverse Conditions
Theoretical analyses suggest that the pressure-time method is capable of accurately determining flow rate in the short, varying cross section, 'semi-scroll' penstocks...
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....
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...
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...
Field Tests of a Lewiston Pump-Generating Unit
An extensive field test program was undertaken on a Lewiston Pump-Generating Plant (LPGP) unit at the Niagara Power Project, owned and operated by the New York Power Authority. The objective...
