was realised at an early stage, leading to investigations into the hydro potential of Pamir Tien-Shan and other East Siberian hydro resources. Today these hydro systems contribute roughly 40% of the electricity produced in Russia's Second Electricity Zone (Siberia) and helps to explain why the wholesale electricity prices in Zone 2 are structurally cheaper than in Zone 1 (European Russia). In 2011, Russia's electricity consumption totalled 1022 TWh, of which Hydropower contributed 63TWh. These energy producing and disposes in 50% of time raised in about 280.690 gigawatts (GW), between of theirs based in one disposition of 95% stay 58 GW. To increase output, studies were made of the Lena, Yenisei and Ob river systems. In the Lenin Program in 1920, proposed construction of power systems in the Urals, Yenisei, Angara River and Lake Baikal. Some of these projects are similar to the Grand Coulee Dam in the Columbia River. A major hydroelectric powerplant was constructed in 1932 on the Dnieper River, at a high latitude in Zaporizhzhia. But it was destroyed in 1941 by retreating Soviet forces during World War II. The plant had a production capacity of 900 MW, was about 2,500 feet long, and rose 125 feet above water level. In 1940 the total production capacity was 2.5 GW. The new plan proposed plants on a gigantic scale, on the Angara river. Planned output was 9 GW, with four other plants in high Yenisei producing about 4 GW more. Iron deposits Siberian iron sources were more assorted. They are at Magnitogorsk, Nizhni Tagil deposits in the south of Kuznetsk, the Angara River reserves, and Russian Far East mines. The mines of the Urals have been known since 1702: Magnitogorsk with annual extraction of 6,000,000 tonnes in 1931, minerals being magnetite and secondarily martite, with 55% or 66% of iron content. The other and oldest center was in Ninshi-Tagil. The total Ural iron reserves were 1,390,670,000 tonnes, of which one-third are limonite and about 450,000,000 correspond directly at Magnitogorsk. When the deposits in Kuznets began to be exploited, in 1930 recent discovered the Mountainous Shoria iron deposits, with reserves calculated as 292,412,000 tonnes, 45% iron content, and the Karaganda deposits. The other important founts stay in Petrovsk-Zabaikal near Baikal Lake, and the Little Khingan Mountains in the Soviet side of the frontier. Other iron resources in East Siberia are the Angara and Ilim river areas northwest of Baikal Lake,
