Digest

Fortnightly Magazine - May 2013
ChargePoint is installing more than 80 electric vehicle charging stations around New York.

PV arrays on a single-axis tracking system, along with a SCADA system to monitor and control the various plant systems, including trackers, inverters, substations, the well water supply and treatment system, and the interface with the plant meteorological station. ABB’s North American Renewables team began installation in January.

Transmission

Georgia Power chose 3M’s ACCR overhead conductor to double the transmission capacity on a set of lines that cross wetlands near Savannah, Ga. The upgrade is on a 16.7-mile line linking the Kraft generating plant in Savannah with the McIntosh plant north of the city. The project resolves potential capacity issues by approximately doubling the 230-kV circuits’ line capacity, replacing a steel core conductor with a 3M conductor light enough to be accommodated mostly by existing infrastructure. 

ATCO Electric selected Quanta Services subsidiary Valard Construction to install transmission infrastructure for the Eastern Alberta Transmission Line (EATL) project. Valard will install approximately 310 miles of 500-kV high-voltage direct current (HVDC) transmission line between the Edmonton and Calgary regions. Valard is responsible for all construction aspects of the project, with completion expected by the end of 2014. 

American Transmission Co. is seeking approval from state regulators to rebuild 58 miles of existing 138-kV transmission lines in portions of four southeastern Wisconsin counties: Waukesha, Jefferson, Dodge and Washington. Work on the project includes replacing the majority of the structures and adding new conductors and fiber optic wires to 35 miles of the line. ATC anticipates regulatory approval in spring 2013 and the start of construction in fall 2014. The estimated cost of the project is $64 million with completion expected in spring 2017.

Lone Star Transmission , a subsidiary of NextEra Energy, completed energization of approximately 330 miles of new 345-kv transmission lines and associated facilities. The project, which includes four circuits and five substations, stretches from Scurry County, northwest of Abilene to Navarro County, just south of Dallas. The project is part of a transmission grid improvement program that will add approximately 2,300 miles of 345-kv lines to deliver power from the Competitive Renewable Energy Zones (CREZ) in west Texas and the Texas panhandle to the Dallas-Fort Worth area and other population centers in Texas. 

Southwest Power Pool (SPP) approved the Elm Creek to Summit transmission line project in central Kansas. ITC Great Plains will construct approximately half of the 60-mile, 345-kV line connecting the ITC Great Plains Elm Creek substation, northwest of Aurora, to Westar Energy’s Summit substation. ITC Great Plains, in partnership with Mid-Kansas Electric Co. (MKEC), will build the northern portion of the line and will co-own and operate it with MKEC. Westar Energy will build, own, and operate the southern half of the line. 

Smart Grid

Municipal Energy Agency of Nebraska (MEAN) contracted Open Systems International (OSI) to supply a new SCADA and generation management system based on OSI’s Monarch (Multi-platform Open Network ARCHitecture) platform. The system will include OSI’s next-generation, .NET-based graphical user interface; advanced SCADA functionality; advanced alarm management system; real-time and historical trending; automatic generation control and dispatch; energy market control algorithm; and market operations system software products.
