Joint Economic Evaluation of Pumped Storage in Colorado
This paper summarizes a joint planning study completed in December 1988 on the economic potential of pumped-storage development. The study was unusual in water development investigations...
Efficiency and Vibration Testing
To gather the necessary data to assure the most efficient and reliable operation of the system, Idaho Power Company implemented a plant testing program in 1988. The testing program consists...
Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, jointly owned by Virginia Power and Allegheny Power systems and operated by Virginia Power, has three large tunnels linking the upper and lower...
Tunnels and Vertical Shafts for Pumped-Storage
Economic considerations are of primary importance to the planning and designing of pumped-storage in an electrical generation and distribution system. This paper deals with the optimum...
Mitigation of Ice Effects at Hydroelectric Intake Structures
The design and operation of hydroelectric facilities throughout the northeast United States and Canada must contend with winter conditions for a large part of their yearly operation. During...
Relicensing: The New Rules of the Game
The Electric Consumer Protection Act of 1986 is an elaborate array of procedures and decisional standards that guide the Commission's consideration of both initial license and Federal...
Negotiating with State and Federal Fish and Wildlife Agencies
The Federal Power Act of 1920 (Act), as amended by the Electric Consumers Protection Act of 1986, requires that the Federal Energy Regulatory Commission, in order to adequately and equitably...
FERC's Experience in Analyzing Cumulative Impacts
Since the mid-1980's, the Federal Energy Regulatory Commission (Commission) has assessed cumulative impacts associated with developing proposed hydropower projects. A brief...
Extensive Civil Penalities Apply - FERC Takes Aim at Hydro Operators' Heads
On August 23, 1988, the FERC published rules implementing its new civil penalty assessment authority. Those rules raise various issues of concern for hydro operators, and additional issues...
Using IFIM at the Upper Greenwich Project and Other Hydropower Developments
The Instream Flow Incremental Methodology (IFIM) is widely used at numerous hydroelectric projects today for determining flow releases. IFIM is capable of quantifying changes in aquatic...
Computerized Measurement of Turbine Flow and Performance, Including Penstock Protection
The application of computer technology now makes it possible to measure turbine flows accurately, reliably and economically. The measurement is based on the differential pressure produced...
Efficiency Monitoring Yields Large Revenue Gains
This paper presents a Washington Water Power Company program to increase hydroelectric plant operations' efficiency. This increase is due to improved flow, head, and megawatt...
Development of High Specific Speed Pump-Turbines
The operational range of pump-turbines is continually increasing, especially in the direction of high specific speed installation. In this context, high specific speed refers to units...
Design and Installation Concepts for High Capacity Pump/Turbines
This paper discusses the pre-planned field welding and machining operations utilized for six (6) large pump/turbines, each capable of 508 MW at Virginia Power Company's Bath...
Field Efficiency Tests of a Large Pump-Turbine
The New York Power Authority's Blenheim-Gilboa Pumped Storage Project began commercial operation in 1973. In 1987, the Authority initiated a study of the existing pump/turbines...
Acoustic Flowmeter/Efficiency System Installation at the Niagara Power Project
The New York Power Authority's Robert Moses Niagara Power Project (RMNPP) recently installed an acoustic flowmeter/efficiency system on two 150 MW rated generators. This paper...
Turbine Efficiency Measurements by the Pressure-Time and the Current-Meter Method at Paugan
Paugan generating station was built in the 1920s. Although the generators were converted from 25 Hz to 60 Hz in the mid 1950s, the original runners were in place until recently when a...
Design and Efficiency Testing of a Cross-Flow Turbine
An inexpensive American-made cross-flow turbine was designed, manufactured, and installed at a remote run-of-river site in Northern California. The 400 kW unit includes an innovative automatic...
Fluctuating Pressure Measurements on a Large Hydro Turbine
The New York Power Authority is investigating the feasibility of upgrading the thirteen 150,000 kW turbines-generators at the Robert Moses Niagara Power Station to improve efficiency and...
Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
