AMSC and DoE to collaborate on 10 MW wind turbines

American Superconductor Corporation (AMSC) has entered a Cooperative Research and Development Agreement (CRADA) with the US Department of Energy’s (DoE) National Renewable Energy Laboratory (NREL) and its National Wind Technology Center (NWTC) to validate the economics of a full 10 MW class superconductor wind turbines under development by AMSC.

Under the 12-month programme, AMSC Windtec™, a wholly owned, Austria-based AMSC subsidiary, will analyse the cost of the full 10 MW class direct drive turbine. The NWTC will then benchmark and evaluate the wind turbine’s economic impact in terms of initial and overall energy costs.

AMSC estimates its direct drive generator system would weigh approximately 120 tonnes, compared with approximately 300 metric tonnes for conventional direct drive generators with this power rating.

AMSC Senior VP and Superconductors General Manager Dan McGahn, says: “Superconductors are today proving their tremendous power density and efficiency advantages to electric utilities and large power users. This programme brings those same benefits to power generation and the rapidly growing wind power market.”
