WATER POWER INDICES OF HYDROELECTRIC POWER PLANTS OF THE NARYN-SYR DARYA CASCADE

摘要

Priorities for the utilization of water resources in Central Asia changed after the collapse of the Soviet Union and the formation of independent states. The demand for cotton production in the Syr Darya River Basin declined. Accordingly, the requirements for irrigation releases and diversions from reservoirs of the cascade, most of all from the Toktogul reservoir, decreased significantly as a result of the substantially smaller water consumption norms for other irrigable crops now cultivated on the land formerly given over to cotton. The conditions of cascade power usage in the electric power system also changed, as did the economic relationships between individual power systems of countries in Central Asia. The fuel supply conditions for thermal power plants of the power system changed considerably. Nonuniform tariff policies and other disparities exist in the power administrations of different countries.
