Seattle City Light to Undertake Deployment Study of AMSC's Resilient Electric Grid System
May 15, 2017

SEATTLE, May 15, 2017 (GLOBE NEWSWIRE) -- AMSC (NASDAQ:AMSC), a global energy solutions provider serving wind and power grid industry leaders, today announced that Seattle City Light has agreed to undertake a deployment study of AMSC's Resilient Electric Grid (REG) system. The study will focus on evaluating REG as a solution for a power distribution application within the utility's service area. Seattle City Light's deployment study is a REG application study resulting from AMSC and Nexans' recent Joint Marketing Agreement targeting the North American market for power distribution applications.

"Seattle City Light continuously evaluates new technologies that can increase the capacity and reliability of our system in ways that reduce costs, as well as minimize the impact of the electric grid infrastructure on our customers and our environment," said Tuan Tran, Director of Energy Delivery Engineering at Seattle City Light. "Technologies that offer us compact, efficient, low environmental impact, and cost effective solutions, such as the Resilient Electric Grid system, are of great interest to Seattle City Light."  

AMSC's Resilient Electric Grid system is an innovative approach to the power distribution system that is designed to increases reliability and capacity of the electric grid. By enabling the use of transmission and distribution assets in a way that is not feasible with traditional technologies, the REG system is designed to significantly increase grid reliability and increases load-serving capacity, while limiting the need for additional grid infrastructure, which mitigates environmental impact.

"The Seattle Washington, area is one of the nation's fastest growing and environmentally conscious regions.  Safe, reliable and low impact electrical infrastructure is of particular importance to the citizens of Seattle," said Daniel P. McGahn, AMSC President and CEO. "We believe that the REG system meets these criteria. We are pleased that Seattle City Light is exploring the use of the REG system in its grid, and we look forward to understanding the needs of the utility."

Seattle City Light serves more than 440,000 customers in Seattle, Washington, and parts of its metropolitan area.
