Own consumption
Our Sustainability Policy sets out the commitment to
use water resources consciously, mostly focused on
the solar power complexes, whose energy generation
efficiency depends on the regular cleaning of the
photovoltaic panels. We added some innovations to
further reduce our consumption. For example, since
2021 we have used robots to clean the solar panels
using less water.
Our water comes from the municipal water supply,
surface water, and artesian wells, depending on the
location and availability of each region. Consumption is
monitored monthly and, whenever there is a deviation,
actions are initiated to investigate and correct the
causes. We assess the exposure of our activities
to local risks, such as conflicts related to the use
of reservoirs; operational risks, e.g., leaks, outages
and dam bursts; climatic risks like microclimate; and
hydrological risks, such as low inflow and sources of
water in water-stressed areas.

Water quality
Focused on water quality at our reservoirs and on increasing water
security, we develop the Water Quality Monitoring Program, which is
responsible for overseeing the conditions and transformations of the
aquatic environment in the areas of influence of the projects, when
they are operation, and the dynamics of our reservoirs.
The program, which is based on the quality standards set forth by
Conama Resolutions 396/2008 and 357/2005, makes it possible
to generate concrete data that helps the competent bodies to carry
out water management, and assesses water quality in the monitored
springs, according to criteria defined for
use in subsistence irrigation projects in
the communities surrounding
the projects.
Our operations do not impact water
availability in the regions where
we operate. Energy generation in
hydroelectric power plants only
influences the flow of rivers, since the
water resources are dammed to drive
the energy-generating turbines. The
entire volume that passes through the
turbines is returned to the system with
quality equal to or higher than that
recorded at the entrance.
We have adopted actions for the
protection of springs and, by means
of reforestation incentives, we
encourage rural landowners to develop
conservation initiatives.
