These savings are the result of energy efficiency projects  


Comerc ESCO customers have been able to reduce the amount of energy used for lighting by more than 70%. Comerc ESCO is the energy efficiency unit of Comerc Energia. These savings are the result of energy efficiency projects implemented in 2016 and 2017, at no investment on the part of our clients.

Comerc ESCO Director Marcel Haratz explained that the first step in the process is a study to find opportunities to reduce energy use by replacing equipment with more efficient versions. “This diagnostic includes any investment required, and the customer pays us back on a monthly basis as a percent of their energy savings. In other words, customers get an immediate reduction in their power bill and new, more efficient equipment,” he added.

Energy efficiency projects apply not only to lighting, but also to refrigeration, engines, water pumps and capacitor banks, among others.

Brazil is one of the most energy wasteful countries

Brazil is ranked next-to-last in the American Council for Efficient Economy (ACEEE) list of 23 counties ranked by energy efficiency. In 2016 alone, Brazil wasted 47,500 GWh, more than 13% of the energy used, or 46% of the output of the Itaipu power plant in that same year.

Energy Service Companies (ESCOs) have been around for many years, and in Brazil have been capturing more and more market, especially after the country signed the Paris Agreement (COP 21), which set a 10% increase in energy efficiency as the nation’s target for 2030.

According to the Comerc ESCO Director, “while there is an awareness of the importance of using energy from clean sources, we must also pay attention to how we use energy. There are huge opportunities to reduce the amount of energy we use and waste.”

Waste is expensive

Waste can also result in fines. For example, incandescent light bulbs have been banned in Brazil since 2015.  These lamps use up to eight times as much energy as LED (light-emitting diode) bulbs. Any business using incandescent lamps between 41 and 60 watts can be fined up to R$ 1.5 million.
