The system makes it possible to use the electric energy produced by the trains when they are braking and return it to the general grid in order to either be consumed by the own operator in other equipment like escalators, stations or offices, or be stored.

With this technology, which will be initially installed for a pilot test on line 2 of the metro network, Río de Janeiro Metro could recover between 10 and 30 percent of the energy consumed and therefore reduce its energy bill and carbon dioxide emissions.
