Instream Flow Methodologies and Requirements
Instream flow is a term applied to the discharge occurring downstream from and at least partly controlled by a dam or diversion structure. The volume and timing of instream flows most...
Bio-Economic Models for Measuring the Economic Effects of Hydropower on Anadromous Fish Populations in the Pacific Northwest
An empirical model is presented for predicting the net economic value of changes in recreational catch of salmon and steelhead in Oregon, Washington and Idaho associated with construction...
Feasibility of Cold Water Releases from Lake Britton
The Pit River in Shasta County, California, is the site of the Pit 3, 4 and 5 Project, a major hydroelectric facility operated by the Pacific Gas and Electric Company (PGandE) under Federal...
The Council's Strategy for Improving Fish Passage
The Columbia River Basin Fish and Wildlife Program was developed by the Northwest Power Planning Council in 1982 and amended in 1984 and 1987. The program is likely the largest ongoing...
Water Management for Juvenile Fish Passage
The regional goal of restoring upriver runs of adult salmon and steelhead requires increased survival of the juvenile fish migrating to the ocean. Juvenile fish survival requires: (1)...
A Juvenile Fish Bypass Program at Columbia River Basin Projects
Hydroelectric development in the Pacific Northwest region has altered the natural flow of the Columbia River and its major tributary, the Snake River. This has proven to be detrimental...
Hydropower Simulation: An Overview
Numerous models have been developed for production costing and generation system expansion which include operation of hydropower in the system. These models rely on energy production and...
Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...
Reliable Operation of Hydro-Thermal Power Systems
The demonstrated model allows planners to account for both operating and shortage costs, subject to a constraint on the system failure rate. In addition, the optimal long-term operation...
Pumped Storage and Power System Operations
The 2100 megawatt Bath County pumped storage power station began commercial operation in December 1985 as a jointly-owned project of Virginia Electric and Power Company (Virginia Power)...
Operational Flexibility?A Precious Commodity
This discussion is about Operational Flexibility, as it applies to the generating resources of a large electricity system. The author discusses the situation at Ontario Hydro, operationally...
A Short-Term Hydro Scheduler for Hydro-Thermal Power Systems
This paper presents HYDSIM (Hydro-electric Simulation), a new versatile computer model developed to simulate the hourly or daily operation of a large network of multi-purpose reservoirs...
Real Time Hydropower Scheduling for Niagara Mohawk Power Corporation
Niagara Mohawk Power Corporation (NMPC) presently manually schedules their hydro system of 660 MW (80 stations in ten river basins). The scheduling procedures are labor intensive and relatively...
Determination of Values of Project Storage for Hydropower Scheduling
The Columbia River is characterized by multiple and sometimes conflicting uses, and its basin extends over many political jurisdictions. To balance pluralistic needs and authorities with...
Marketing Power in the Pacific Northwest
The marketing of power in the Pacific Northwest is a process intimately tied to the management of the Columbia River system. This paper describes the characteristics of the river and transmission...
Columbia River Treaty Perspectives
The Columbia River Treaty was signed in 1961 and ratified by the governments of Canada and the United States in 1964. The Treaty required British Columbia to construct three large storage...
Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...
Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...
Hydropower Development of China's Yangtze River
The Yangtze has eight times the hydro potential of the Columbia River basin, currently the largest developed hydro system in the world. In order to pursue economic development through...
Rain Data Telemetry for Operation of a Hydro-Reservoir
The Collywobbles hydro-electric station operates 42MW with very little river storage. Raindata is collected from 11 gauges distributed in the 5000 km**2 catchment and telemetered to a...
