ABSTRACT
It is understood that the ecological purity of a tidal electric plants (TEPs) is relative, since its construction and operation, like any of man’s intrusions in nature, could not remain without repercussions. TEPs are distinguished, however, by the fact that these repercussions are minimal as compared with other types of power plants, and it is possible to denote them as background repercussions. The influence exerted by TEPs on the environment has been investigated in Russia since 1924 on the initiative of their designer – the S. Ya. Zhuk All-Union Scientific Research Institute for Design and Exploration. A reduction in water exchange cannot be appraised on the negative side alone. In those cases when the maximum velocity of the water exceeds 2m/prior to construction of the plant, its reduction will contribute to the possibility of the existence of bottom communities that are more diverse with respect to type of composition and richer with respect to biomass.
