Pilot Projects in BrazilEnel “model” digital meters in the area of Fortaleza

Enel, with Endesa, is developing a pilot remote management project in Brazil, using the same metering technology that Endesa is installing in Spain. The pilot project will be implemented through Coelce, Endesa's electricity distribution subsidiary operating in the State of Cearà, Brazil.

The pilot project was launched in Fortaleza through the installation of meters of the model developed by Enel Distribuzione. The project also envisages the installation of concentrators for the data collected by meters in transformer stations and training days for the technicians of local Enel Group distribution companies.

Brazil is the first country in Latin America to begin developing a regulatory framework for remote management.
