AMSC Celebrates 100th STATCOM Sale

AMSC's 100th STATCOM sale was recently made to Iberdrola Renewables, LLC, a company that is involved with more than 50 renewable energy projects in the United States

Devens, MA – June 13, 2012 – AMSC (NASDAQ: AMSC), a global solutions provider serving wind and grid leaders, today announced the sale of its 100th static synchronous compensator (STATCOM) solution. AMSC's D-VAR® STATCOM systems provide a powerful and cost effective source of reactive power for a wide range of operational needs. They can be used to correct voltage instability problems on transmission networks; provide dynamic steady-state voltage and power factor control and regulation on transmission and distribution networks; protect industrial facilities requiring premium power quality; and support a stable point of interconnection for distributed generation facilities and large-scale wind and solar farms.


AMSC's 100th STATCOM sale was recently made to Iberdrola Renewables, LLC, a company that is involved with more than 50 renewable energy projects in the United States. Iberdrola Renewables will utilize AMSC's D-VAR system to connect the 48 megawatt Groton Wind Farm to the power grid in central New Hampshire later this year. According to Iberdrola Renewables, the project currently employs more than 150 construction personnel and, when operational, will provide more than half of the annual municipal budget of the town of Groton. The STATCOM will be manufactured in AMSC's Middleton, Wisconsin facility.

"We are continually striving to provide our global customer base with reliable and cost-effective solutions to their power quality and grid connectivity issues," said Daniel P. McGahn, President and CEO, AMSC. "Today's milestone is a tribute to our team's years of commitment – their dedication, determination and innovation. It also demonstrates the quality, reliability and versatility of our products and the enduring value they provide to customers worldwide."

Power grids around the world are dealing with the dual challenge of meeting rising energy demand and integrating new energy sources. The result can be bottlenecks, grid disturbances and stability problems between the transmission systems and the point of generation. When placed at the substation of a renewable generation facility, AMSC's D-VAR STATCOM enables the plant to safely and efficiently connect to the power grid. The device also ensures that the facility will meet utility interconnection requirements. When used on the transmission or distribution system of an electric utility, the D-VAR system constantly monitors the power grid and automatically and instantly stabilizes voltage to enable higher power transfer through existing power lines with increased reliability and efficiency.

AMSC's D-VAR STATCOM reactive compensation solutions can also be used at large industrial facilities to correct voltage instability problems caused by the start-up of a large drives, motors, metal shredders, crushers, sawmills, pump or pipeline stations, shipyards, coal mines, feed plants and other similar energy-intensive processes. When placed at the point of load connection, D-VAR systems will support and stabilize voltage, ensuring premium power quality.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
