$AMSC Announces $8 Million in D-VAR® System Orders

D-VAR Systems to Support Renewable Connectivity Applications in the U.K. and Industrial Power Quality in the U.S.

DEVENS, Mass., Nov. 29, 2017 — AMSC (NASDAQ:AMSC), a global energy solutions provider serving wind and power grid industry leaders, today announced four new D-VAR® STATCOM system orders valued at over $8 million. Two of the orders serve the renewable energy sector and are expected to be used for connection of wind power plants to the electric grid in the United Kingdom, as well as to provide voltage regulation by responding dynamically to varying load conditions. Two of the orders serve the industrial power quality sector in the United States. Revenue from these four D-VAR® orders is expected to be recognized in fiscal year 2017.

AMSC’s D-VAR interconnection and reactive power compensation solutions are designed to ensure high network performance and stability. The system is a powerful, cost-effective way to provide continuous voltage regulation, improve voltage stability, meet interconnection requirements, and dynamically provide grid support where it is needed.

“We believe that these D-VAR orders represent continued progress toward our objective to grow our Grid revenues year over year,” said Daniel P. McGahn, President and CEO, AMSC. “I am pleased that these orders for industrial applications in the U.S. include two repeat customers in the power quality market.”

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 D-VAR system is designed to be able to detect and instantaneously compensate for voltage disturbances by dynamically injecting leading or lagging reactive power into the power grid. These solutions are also designed to augment the overall performance of wind farms and to enable developers to meet grid interconnection requirements.

D-VAR reactive compensation systems are classified as Static Compensators, or “STATCOMs,” a member of the FACTS (Flexible AC-Transmission System) family of power electronic solutions for alternating current (AC) power grids.
