American Superconductor Books Additional Order For Wind Farm Voltage Regulation System

WESTBOROUGH, Mass., -- American Superconductor Corporation (Nasdaq: AMSC), a leading electricity solutions company, today announced the sale of its D-VAR(R) voltage regulation system to the prime contractor for a Nebraska-based wind farm -- the seventh time customers have chosen AMSC's products to reliably and safely interconnect major wind-generated power facilities to the electrical transmission grid.

The Ainsworth Wind Turbine Project will be located south of Ainsworth, Nebraska, and is owned by Nebraska Public Power District (NPPD). The project will comprise 36 Vestas V82 wind turbines with an installed capacity of 60-megawatt (MW), and will be constructed on behalf of NPPD by RES America Construction Inc. of Austin, Texas.

The D-VAR system, slated to be commissioned this summer, constantly monitors voltage where the wind turbines connect to the transmission grid. Instead of allowing voltage to vary as the wind fluctuates, the D-VAR system and its ancillary equipment dynamically regulate the voltage at the point of connection to the transmission grid to a desired level.

Overall, this is the sixth wind farm in North America and the seventh worldwide to incorporate AMSC's advanced voltage control technologies. These projects bring the total wind-generated electric power served by AMSC's D-VAR systems to more than 550 MW (or enough clean, zero-emission energy to meet the needs of more than a quarter million homes). It is also the third North American wind farm to pair AMSC's D-VAR systems with Vestas wind turbines.
