The Zemu Glacier drains the east side of Kanchenjunga, the world's third highest mountain. The glacier is the source of water for numerous rivers, as it feeds them when it melts. One of them is the Teesta River, which has garnered large attention in the past few years because of a proposed 3500 MW hydropower plant. At the moment the Government of Sikkim has only been able to run a 510 MW plant on the river. Owing to the location of the river in an earthquake prone area, the hydropower plants will be a run of the river project.
