Will Brazil be the next big market for smart meters? The world’s big smart meter makers seem to think so. Silver Spring Networks announced Wednesday that it would work with Swiss metering giant Landis+Gyr on a Brazilian smart grid solution — and L+G is already testing its smart meters with Brazilian regulators. While those two work on a wireless smart meter solution, powerline carrier systems are also trying the market — Echelon has a deal to supply its technology to Brazilian smart meter maker ELO Systemas Electronicos, and Esco Technologies subsidiary Aclara is targeting Brazil as well as South American countries like Colombia. Stopping power theft and fixing too-frequent power outages are the key concerns for Latin American utilities, which could open the market to system-on-a-chip makers as well.
