Paz hydropower plants (Paz cascade) - a cascade of hydroelectric power stations on the Paz river (Patsoyoki) in the Murmansk region of Russia and Norway .
Feature
The Paz River flows from Lake Inari ( Finland ) and, for most of its course, is a border river between Russia and Norway. Both Russian and Norwegian hydroelectric power stations are located on the river. The mode of operation of a hydropower plant is regulated by international treaties (Agreement between the Soviet Union and Norway of December 18, 1957 on the use of hydropower from the Paz River, Agreement of 04.29.59 Regulating the regime of Lake Inari through a hydroelectric power station and Kaitakoski Dam between the USSR, Finland and Norway). About 85% of the electricity produced by the Russian hydroelectric power stations of the cascade is exported. Cascades of hydroelectric stations operate in automatic mode.
The Russian hydropower plants of the Paz cascade are part of TGK-1 , and most of the time they are isolated from the UES of Russia in the NORDEL power system.
The cascade includes hydropower plants Kaitakoski , Yaniskoski , Rayakoski , Khevoskoski , Skugfoss , Melkefoss , Borisoglebskaya .
The capacity of all hydroelectric power stations of the cascade is 275.9 MW, the average annual output is 1475 million kWh . Russian hydropower plants of the cascade, respectively, 187.9 MW and 988 million kWh.
