American Superconductor Corporation, together with its subsidiaries, provides megawatt-scale power resiliency solutions worldwide. The company operates in two segments, Grid and Wind. The Grid segment offers products and services that enable electric utilities, industrial facilities, and renewable energy project developers to connect, transmit, and distribute power under the Gridtec Solutions brand; and engineering planning services. It provides transmission planning services, which identify power grid congestion, poor power quality, and other risks; grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems; resilient electric grid systems, which provide protection against the adverse effects that follow the loss of critical substation facilities in urban areas; D-VAR systems used for controlling power flow and voltage in the AC transmission system; actiVAR system, a fast-switching medium-voltage reactive compensation solution; armorVAR system installed for reactive compensation, power factor correction, loss reduction, utility bill savings, and mitigation of common power quality concerns related to power converter-based generation and load devices; and D-VAR volt var optimization (VVO) that serves the distribution power grid market. This segment also offers ship protection systems, which reduce a naval ship's magnetic signature; and in board power delivery systems, power generation systems, and propulsion systems. The Wind segment designs wind turbine systems and licenses these designs to third parties under the Windtec Solutions brand. It supplies power electronics and software-based control systems, and provides customer support services to wind turbine manufacturers. This segment's design portfolio comprises a range of drivetrains and power ratings of 2 MW and higher. American Superconductor Corporation was incorporated in 1987 and is headquartered in Ayer, Massachusetts.

The rapid proliferation and increasing capabilities of Battery Energy Storage Systems (BESS) represent a clear emerging threat. As the cost of battery storage continues to decline, BESS are increasingly being deployed by utilities and grid operators not just for energy storage, but also for a wide range of grid stabilization services, including voltage support, frequency regulation, and dynamic reactive power compensation. This multi-functional capability allows BESS to directly compete with and potentially displace dedicated grid stabilization products, such as AMSC's D-VAR® systems, by offering a more comprehensive and flexible solution from a single platform.
