RUSSIA. Yenisei River. Sajanogorsk. 2018. The hydropower plant Sajano-Shushenskaya GES. It is the largest of Russia and the 9th largest in the world. Here, the water power of the Yenisei is harnessed. The plant was built to power the huge aluminum factories in Krasnoyarsk. With two giant dams they created lakes of almost 400km length.
