Xcel Energy plan for Clovis-area transmission upgrades to improve reliability in the region—which is also the site for the planned $1.5 billion landmark Tres Amigas project. If completed, Tres Amigas would tie together the Eastern, Western, and ERCOT grids for the first time. The Xcel plan involves the construction of the new Pleasant Hill substation northeast of Clovis and two new 230-kV transmission lines that will connect Pleasant Hill with the existing Roosevelt County and Oasis substations, which also are targeted for capacity upgrades. The improvements were among a group of capacity projects identified by the Southwest Power Pool in a 2009 reliability study.
CoServ Electric , an electric cooperative in Texas, selected the Ecologic Analytics meter data management (MDM) system for its advanced metering and distribution technology initiative. CoServ chose Ecologic Analytics MDM to integrate with its Landis+Gyr metering systems and back-office systems.
Prairie Land Electric Cooperative engaged KamTech Systems and Clevest Solutions to support its project to replace 16,000 mechanical meters and upgrade 9,000 electronic meters in northern Kansas with new Landis+Gyr units. Meter technicians use handheld devices throughout the day to complete orders, and at the end of the day information is synchronized with the Clevest system and then updated in Prairie Land’s customer information system.
Cedar Falls Utilities selected Tantalus as the technology platform to support the utility’s existing fiber-to-the-home and wireless broadband networks. Cedar Falls chose Tantalus to implement an initial deployment of advanced metering infrastructure using Itron meters. The Iowa Association of Municipal Utilities contributed to the project with funds from a U.S. DOE grant.
Concho Valley Electric Cooperative installed the FlexNet utility communications network from Sensus as part of a distribution system upgrade in a 10-county territory surrounding San Angelo, Texas. The FlexNet long-range radio system communicates via dedicated, primary-use, FCC-protected spectrum. Full deployment started in August and will be completed by late fall 2012. The project calls for installation of 13,000 Sensus iCON electric meters, mostly in residential applications. Fourteen base stations and antennas will create a network canopy covering more than 4,000 square miles of mainly rural terrain.
Nebraska City Utilities selected Elster’s Q Sonic Plus meters for its natural gas transmission main extension to areas south and west of Nebraska City and a service line to an Omaha Public Power District power plant. The Q Sonic Plus meters provide comprehensive measurement of gas flow, with the capability to operate in both upstream and downstream environments.
EVs & Storage
Evatran completed the first three installations of its Plugless Power wireless electric vehicle (EV) charging technology with Apollo Launch partners—including the Hertz Corp., Duke Energy, and the Clemson University International Center for Automotive Research. Evatran says the installations on Nissan LEAF vehicles are the first passenger EVs in the world with full wireless charging capability. The Plugless Power partners are testing wireless charging technology on their Chevy Volt and Nissan LEAF vehicles, in a variety of applications. The Plugless Power technology is based on electromagnetic induction with Evatran control software and coil designs to extend efficient power transfer over an air gap of
