AMSC Overview

American Superconductor Corporation (AMSC), along with its affiliated entities, delivers robust, large-scale power infrastructure and resiliency solutions across the globe. Its operations are primarily divided into two distinct segments: Grid and Wind. The Grid segment, marketed under the Gridtec Solutions brand, supplies essential products and services designed to empower electric utilities, industrial operations, and renewable energy developers. These offerings facilitate the seamless connection, transmission, and distribution of electrical power, complemented by expert engineering and planning services. Within this segment, AMSC delivers transmission planning to diagnose issues like grid congestion, suboptimal power quality, and other systemic vulnerabilities. It provides critical grid interconnection solutions for large-scale renewable projects like wind and solar farms, alongside comprehensive power quality and transmission & distribution (T&D) cable systems. Key technologies include its D-VAR® systems for precise control of power flow and voltage within AC transmission networks, the actiVAR™ solution for rapid medium-voltage reactive compensation, and the armorVAR™ system, which enhances power quality, corrects power factor, reduces energy losses, and mitigates concerns from converter-based devices. Furthermore, D-VAR® VVO technology optimizes voltage and reactive power on the distribution network. Additionally, the Grid segment extends its expertise to naval applications, supplying advanced ship protection systems that minimize magnetic signatures, along with integrated power delivery, generation, and propulsion systems, as well as specialized transformers and rectifiers. The Wind segment, operating under the Windtec Solutions brand, focuses on designing cutting-edge wind turbine systems and subsequently licensing these innovative designs to external manufacturers. Beyond the core designs, this segment provides crucial power electronics, sophisticated software control systems, bespoke engineered solutions, and ongoing customer support for wind turbine producers. Its comprehensive design portfolio encompasses various drivetrains and power ratings, starting from 2 megawatts. Established in 1987, AMSC maintains its corporate headquarters in Ayer, Massachusetts.
