DEVENS, Mass., May 1, 2014 (GLOBE NEWSWIRE) -- AMSC (Nasdaq:AMSC), a global solutions provider serving wind and power grid industry leaders, today announced that it has successfully installed and commissioned three D-VAR® STATCOM systems in Africa and the United States. The new installations are connecting renewable power plants to the grid and ensuring power quality at industrial sites. Additionally, AMSC announced that it has won four new D-VAR contracts in Australia, North America, and South Africa. For all of these new contracts, the D-VAR system will be used to meet grid interconnection standards and safely and efficiently connect wind and solar energy generation plants to the power grid.
Located at the wind or solar plant substation, AMSC's D-VAR STATCOM provides a renewable energy integration solution that allows power plants to stay online and helps prevent the nuisance tripping of solar inverters and wind turbine generators. Customers utilize AMSC's D-VAR solutions to provide dynamic voltage control, power factor correction and post-contingency reactive compensation to stabilize the power grid and prevent undesirable events such as voltage collapse. The new installations include:
Kahuku Wind project in Oahu, Hawaii: First Wind, an independent U.S.-based wind energy company, is using the solution to connect the 30 megawatt (MW) Kahuku Wind project to the Hawaiian Electric Company's (HECO) grid.
Cookhouse Wind Farm near Port Elizabeth, South Africa: Consolidated Power Projects (CONCO), South Africa's largest high voltage construction company, has installed the D-VAR system as part of its efforts to connect the 140 MW project to the Eskom's grid. Eskom is South Africa's primary electric utility.
Every year, billions of dollars in revenue are lost due to momentary power quality problems. The slightest variations in voltage can cause hours of downtime, resulting in lost productivity and the need to recalibrate equipment. When used to enhance power quality, AMSC's D-VAR system can cost effectively provide efficiency, protection, and a secure connection, helping industrial facilities achieve smooth operation and realize their full profit potential. AMSC also installed a D-VAR system for a power quality application at the Yellowstone Valley Electric Co-op in Montana, United States. The Yellowstone Valley Electric Co-op is using a D-VAR system to mitigate the voltage sags and flicker caused by large power draw from a local car shredding facility.
