Total value:
€344 million, share €241 million

Construction period:
December 2010 – July 2015

The El Quimbo powerhouse, located in the District of Huila on the Magdalena River, will have an installed capacity of 400 megawatts with average energy production estimated at 2,216 GWh per year, using two vertical axis turbines and a tank with a storage volume of 1,824 hm³.

The project involves the construction of a main dam in loose materials with a concrete surface (CFRD) 150 m high and 635 m long, with the spillway located on the left side of the dam body, controlled by four sluices and with a “trampoline” drainage channel for energy dissipation.

There are also plans for a secondary dam 66 m high and 410 m long.
