Since 2019, the Águas do Brasil Group has
been investing in actions to increase the
share of energy generated by renewable
sources to operationalize its activities.
Environmentally responsible for saving
resources and emissions, these projects
strengthen business efficiency since
electricity is one of the main operating
costs in companies in the sanitation sector.
Energy generated by clean sources has
already avoided the emission of 22,000
tons of CO₂ into the atmosphere (or 735,000
trees planted), and distributed generation
has reduced 856 tons of CO, equivalent
emitted into the atmosphere (or 28,494
trees planted). This energy is enough
to supply 4,665 homes with an average
consumption of 300 kWh/month for a year.
In addition to the energy supplied by
regional operators, predominantly
produced by hydroelectric plants, the
Group entered into a 10-year contract to
purchase clean energy on the free market
in some regions. Also, within a distributed
generation model, the Group has been
leasing power plants through distributed
generation contracts in partnerships with
investors since 2019. Currently, it has a
production capacity of 20,000 MWh/year,
generated by various sources such as
biogas (from landfills), photovoltaic, and
hydropower, supplying clean energy for

the operations of the low voltage units
in the states of Rio de Janeiro and Minas
Gerais. In 2021, the Group extended this
initiative to operations in São Paulo, and
as a result, there will be an increase in
generation capacity to 23,500 MWh/year
by the end of 2022, which will represent
approximately 61% of the energy needed
to meet the demands of the low voltage
units of the entire Group.
Other projects that have a significant
impact are the studies of the largest
energy-consuming units responsible
for a considerable portion of electrical
energy consumption.
