EFFICIENT WATER USES IN COLBUN

HOW DO WE USE WATER IN OUR POWER PLANTS?

Our power plants use water from different sources, depending on their location and

type of technology

Run-of-the-river

Hydroelectric Power

Plants

The surface water of a river is diverted to produce energy, with the commitment to restore the same volume and conditions of waterflow downstream .

Reservoir

Hydroelectric Power

Plants

The surface water utilized for electricity generation comes from reservoirs, and these resources are replenished within the same basin.

Thermal

Power Plants

Our thermal power plants rely on water for their cooling processes

• At Santa María and Fenix facilities, seawater serves as the primary source, which is returned to the sea post-cooling

Photovoltaic

Power Plants

We use water for washing panels at our solar farms

• We prioritize finding cleaning solutions that minimize water use
