The Zeya Dam is a concrete gravity dam on the Zeya River by the town of Zeya, Amur Oblast, Russia, north of the Chinese border. On average the Zeya Hydroelectric Power Station generates 4.91 terawatt-hours (17.7 PJ) of electricity per year. It is equipped with six hydro-turbines, four with capacity of 225 megawatts (0.302×10^6 hp) and two with capacity of 215 MW (0.288×10^6 hp).[1]

Overview

The Zeya Reservoir (Russian: Зейское водохранилище) is located in the upper course of the Zeya, below the southern foothills of the Toko-Stanovik, a subrange of the Stanovoy, to the north of the junction of the Tukuringra and Dzhagdy ranges.[2] The reservoir is kept at a regulated depth of 93 metres (305 ft). A narrow, 40-kilometre-long (25 mi) valley separates the dam water body from the vast surface of the reservoir. The Baikal-Amur Mainline railway runs along the north shore, where a 1,100-metre-long (3,600 ft) bridge has been constructed.

Settlements on the shore of Zeya Dam include Beregovoy, Khvoyny, Gorny, Verknezeysk, Bomnak and Snezhnogorsk.
