Construction Of A Power Plant

Abstract
A pilot seawater pumped-storage power plant (maximum output 30 MW) was
recently completed in Okinawa Prefecture, Japan. The plant site is located in the
northern part of the main island of Okinawa, and many natural areas remain.
Numerous precious organisms, on the verge of extinction, inhabit the area of the
plant and its environs. The current study describes environmental conservation
measures undertaken before construction, under construction and after
construction of a power plant in a natural green space.
The environmental conservation measures implemented during the
construction of the power plant focused on noise, vibration, and sanitary
wastewater. However, during construction, measures for controlling the red-soil
sediment yield and protecting precious animals were more difficult to realize.
The sediment yield was measured by a catch drain, minimized using a weir,
sedimentation ponds, and slope protection. Provisions for the protection of
nature included fences, the transplantation of vegetation, and the preservation of
wild animals.
Keywords: power plant, environmental conservation, red-soil, precious animals.
1 Introduction
The geographical features of Japan, which is surrounded by the sea, are well
suited to seawater pumped-storage power plants. However, previously, seawater
pumped-storage power plants could not be developed because of difficulties in
resolving a number of technical and environmental problems associated with the
