PUMPED STORAGE ENVIRONMENTAL EFFECTS: ASSESSMENT OF RESEARCH NEEDS

PDF Version Also Available for Download.

Description

Pumped storage hydroelectric systems convert large quantities of electrical energy to a form that may be stored and efficiently reconverted to electricity. Water is pumped from a lower reservoir to an upper reservoir during periods of low power demand. The stored water is then used to generate additional power when demand peaks. Since the basic requirements of the system are simple, the design of individual plants and their locations vary widely. These variations make assessment of the generic environmental impact of the pumped storage systems difficult. In addition, most studies have not examined the impacts of an operating plant comprehensively. ... continued below

Description

Pumped storage hydroelectric systems convert large quantities of electrical energy to a form that may be stored and efficiently reconverted to electricity. Water is pumped from a lower reservoir to an upper reservoir during periods of low power demand. The stored water is then used to generate additional power when demand peaks. Since the basic requirements of the system are simple, the design of individual plants and their locations vary widely. These variations make assessment of the generic environmental impact of the pumped storage systems difficult. In addition, most studies have not examined the impacts of an operating plant comprehensively. Assessment of the environmental effects of development and operation of a pumped storage plant requires an extensive set of baseline information, which is deficient in several aspects at the present state of the art. Additional research is needed to: • identify species groups likely to survive and reproduce in pumped storage reservoirs, their relationships and habitat preferences, and the basis for their production; • characterize anticipated reservoir ecosystem community development and relate it to physical characteristics of pumped storage reservoirs; • define effects of plant design and operating parameters on transport of organisms through the pump/turbine facility, accounting for behavior of the organisms potentially impacted; • access the mortality rate of organisms likely to pass through pump-turbines; • identify the relative advantages and disadvantages of screening intake structures to prevent passage of large organisms through the plant; • assess the effects of currents and water withdrawal on migration and movement of aquatic species; • investigate the effects of fluctuating water levels on the littoral zone and riparian communities, effects of stranding on entrapment of fishes, and effects on fish spawning; and • review the applicability of water quality and ecosystem models to pumped storage systems and develop more refined models for predicting effects of changes in water quality on aquatic production.
