in the state of Mato Grosso, Brazil. The dam's hydroelectric power stations have 3 turbines each 102.3 MW, resulting in a total installed capacity of 306.9 MW. Construction on the run-of-the-river type station was initiated in May 2011, and the last unit started operating in December 2019. The dam is part of a planned six power plant "Hidrovia Tapajos/Teles Pires" project to create a navigable waterway connecting the interior of Brazil to the Atlantic Ocean. The waterway will consist of five dams on the Teles Pires river: Magessi Dam, Sinop Dam, Colíder Dam,

are built, while the smaller upstream dams are still in the planning stages by 2019.

Design

The Colíder Dam will be a combination embankment dam with concrete sections for the power stations and spillway. The length of the entire dam will be . The dam will utilize 4.7 million cubic meters of earth and 260 thousand cubic meters of concrete, and will impound a reservoir with a surface area of 182.8 square kilometers. The power plant is being constructed by the Brazilian utility Companhia Paranaense de Energia ( Copel).

Environmental Impacts

To reduce emissions of methane, a powerful greenhouse gas, 82 square kilometers of vegetation were cleared before the reservoir was filled.
