The commitment agreed with Eletrobras and the Sustainability Management System of Itaipu, which provides for the use of more economical fuels that do not harm the environment, made possible the significant reduction in consumption of fossil fuels in relation to 2014. Among the various actions undertaken there was the renewal of our fleet with more efficient vehicles and increased use of electric vehicles and powered by biomethane or ethanol, to the detriment of diesel and gasoline.

There was also a significant reduction in gas consumption in the pantries serving the company by using electric coffee makers and implementing solar water heating system in some pantries located in Foz do Iguaçu. Furthermore, in 2014 two types of coffee were prepared: sweetened and sugarless. In 2015, only coffee without sugar was done, which reduced the coffee waste and also the preparation time.

The energy consumption is directly related to maintenance activities and installation of new equipment and although it happens all the years, it may cause significant variation, because some activities require more electricity than others. Still, in 2015 there was a decrease in electricity consumption as a result of joint work with Eletrobras for implementing the ISO 50001 standard in Itaipu, whose first internal audit is scheduled for November 2016.

Energy savings in the period was 45.06%, resulting in reduced consumption of 610,649.80 kWh, due to actions of modernization of access roads’ lighting system on the Brazilian side of the plant; optimization of internal lighting, electrical infrastructure and air conditioning units; and updating of the pumping system of the plant’s water treatment plants. After the certification process, the buildings will be able to apply the seal Procel Edifica of the National Energy Conservation Program.
