The water used in the hydroelectric power plants to generate electricity is not consumed, but only diverted to move the turbines, therefore is not considered in the total volume of water consumed. Likewise, the seawater used by Eletrobras Eletronuclear to cool the secondary system of the Angra 1 and 2 nuclear power plants is fully returned to the sea with a slight rise in temperature, which is constantly monitored to comply with the standards established by environmental laws and to prevent any impact on the aquatic wildlife.

We also promote the reuse and recycling of water, mainly through wastewater treatment, capturing rainwater and intelligent use in cycles, adding about 3 million m³ in reused water in 2015, in our companies Eletrobras Eletronorte, Eletrobras Eletronuclear, Eletrobras Eletrosul, Eletrobras Furnas and Eletrobras CGTEE, in addition to Itaipu.

Electricity consumption

Activity 2015 (in Gj)
Administrative activities 380,550
Thermal power generation 500,814
Hydroelectric power generation 615
Transmission 395,604
Distribution​ 24,125
Total 1,301,707

Waste generation​​

In 2015, we disposed of 1,430,168.34 tons of waste, mostly to industrial landfills and to reuse. At our companies, treatment of solid waste complies with the laws in effect.
