The city of Miami launched Monday a $200 million smart-grid and renewable energy initiative that city officials said would be one of the most extensive of its kind in the country.

Under the initiative, which “proposes” to use federal economic stimulus funds, the utility Florida Power & Light will deploy more than 1 million smart meters to every home and most businesses in Miami-Dade County. These meters automatically transmit energy usage data to the utility’s back office.

“This begins the transformation of Miami into the first truly smart-grid system in the nation,” said Miami Mayor Manny Diaz at a press conference. “It is a model that supports and embodies the goals of the stimulus bill.”

General Electric will supply the smart meters and may later provide other smart control systems. Redwood City, California-based Silver Spring Networks will provide the wireless network infrastructure that the utility will use to communicate with its meters. Cisco will help design and implement a communications platform within the county’s transmission and distribution grid and provide customers with home energy management information and controls.

As part of the initiative, Florida Power said it would conduct studies around the effectiveness of different energy-saving technologies. These trials will include 1,000 households in Miami-Dade and will look at in-home energy displays to manage electricity loads, smart appliances that can switch to lower-consumption modes during peak demand periods, and demand management and demand response software that will manage consumer appliances.
