in the Netherlands, and is available for 50- and 60-Hz applications.

SunEdison signed an agreement with the Chilean mining and steel group CAP to build what is expected to be the largest solar PV power plant in Latin America and one of the largest in the world. The plant is designed to have an installed capacity of 100 MW (DC) and will be located in the Atacama Desert. The plant will be built using SunEdison technology, with more than 300,000 Silvantis monocrystalline silicon modules. Once completed, the project will be managed by the SunEdison renewable operations center.

EVs & Storage

Duke Energy Renewables installed a 36-MW energy storage and power management system at its Notrees Windpower Project in West Texas. Xtreme Power designed, installed, and will operate the system. In addition to increasing the supply of renewable energy during periods of peak demand, Duke expects the system will help stabilize grid frequency. Duke is working with the Energy Reliability Council of Texas (ERCOT) to help manage frequency.

CALMAC is now a member of the Texas Energy Storage Alliance , a technology-neutral coalition of energy storage technology product and service companies. By joining the Alliance, CALMAC will address summer peak energy demands and provide knowledge of thermal energy storage for reducing a building’s peak energy load.

Tennessee Valley Authority (TVA) plans to install revenue-grade electric vehicle (EV) charging stations in collaboration with selected distributors in its territory. Installation is scheduled to begin in mid-2013. The system includes ClipperCreek charging stations with Itron sensor technologies and a ZigBee communication module. With these stations, TVA can charge utility service vehicles while measuring energy used and retrieving interval data through a ZigBee smart meter interface.

Georgia Power is making 10 smart chargers available to employees at its headquarters in Atlanta to enable EV charging while at work. The program is part of ECOtality’s EVproject—a public-private partnership with the Department of Energy that evaluates the effectiveness of EV charger infrastructure. The company also will add additional chargers at other business locations around the state.


LaGrange County REMC began deploying a Sensus FlexNet utility network and iCon A electric meters for more than 7,000 residential, commercial and industrial customers across parts of four counties in northern Indiana. The utility recently concluded construction and installation of its five base stations. The project is expected to be complete within five to six years as legacy meters are replaced with Sensus digital meters.

Echelon and ELO Sistemas Eletronicos , a large meter manufacturer in Brazil, announced plans to deploy a 3,400 unit pilot—the Parintins City Project—with Eletrobras. ELO’s system consists of a dual mode smart meter that communicates over power line or by radio frequency through Echelon’s multipurpose expansion port (MEP) feature. Echelon is providing smart sensor and metering sub-systems to ELO, using its energy control networking platform. By the end of 2013, ELO will deploy another 12,000 smart meters as part of this project.

Itron signed a contract with Pomerania Gas to supply nearly 200,000 residential and commercial gas meters. The meters will be deployed over the next three
