AMSC Triples Its Global Wind Power Market Reach

PowerModule order enhances VRB Power Systems' wind energy storage device.
Published: April 17, 2007

Westborough, Massachusetts [RenewableEnergyAccess.com] American Superconductor Corporation's (AMSC) PowerModule power converter technology has been selected to manage power for a wind energy storage system in Ireland. AMSC also reported a new order for its D-VAR reactive compensation product slated to enable grid connection of a wind farm in Scotland to the local power grid.

"The D-VAR has become the standard for wind farm operators facing strict grid interconnection standards while the PowerModule's flexibility and configurability makes it ideally suited for many industries and applications such as the renewable energy market."

-- Greg Yurek, AMSC, founder and CEO
Designed to increase the uniformity of electricity from wind farms, AMSC's PowerModule power electronic converters have been ordered by VRB Power Systems of Vancouver, British Columbia, for integration into its energy storage systems. VRB Power's energy storage technology has the ability to store excess wind-generated energy when the demand is low, and release it when the demand exceeds the available wind-generated power.

"AMSC's wind energy solutions are the products of choice for today's wind farm developers and contractors seeking to develop and deploy world class, wind-generation systems," said Greg Yurek, founder and CEO of AMSC. "The D-VAR has become the standard for wind farm operators facing strict grid interconnection standards while the PowerModule's flexibility and configurability makes it ideally suited for many industries and applications such as the renewable energy market."

AMSC also reported an order for a six megaVAR (MVAR) D-VAR system from Scottish Hydro Contracting for the Millennium wind farm, which is under construction in Scotland. This system will help regulate voltage so the 40-megawatt (MW) wind farm can meet the United Kingdom's grid interconnection standards. The Millennium wind farm will be the ninth wind farm located in the UK and the 26th wind farm worldwide to utilize AMSC's D-VAR solution. Delivery of the system is expected in the second half of calendar 2007.

With the addition of the Scottish wind farm and the VRB order, AMSC now has an installed base and orders for D-VAR and PowerModule solutions to serve nearly 3,000 megawatts (MW) of wind power worldwide -- triple the amount served by AMSC a year ago. With approximately 15,000 MW of wind power capacity installed worldwide in 2006, the additional 2,000 MW served by AMSC over the past year represents a significant share of the overall wind power market.

"The VRB Energy Storage System (VRB-ESS) is based on the vanadium-based fuel cell that converts chemical energy into electrical energy. Energy is stored chemically in different ionic forms of vanadium in a dilute sulphuric acid electrolyte. The electrolyte is pumped from separate plastic storage tanks into flow cells across a proton exchange membrane (PEM) where one form of electrolyte is electrochemically oxidized and the other is electrochemically reduced. This creates a current that is collected by electrodes and made available to an external circuit. The reaction is reversible allowing the battery to be charged, discharged and recharged."

It is a rechargeable, large energy storage capacity fuel cell system to compensate for low-wind times.
