While it's a bit outdated, I found a 2004 study online called "Wind Turbine Development: Location of Manufacturing Activity" by REPP. There is a wind energy component supplier in Waitsfield, VT (Northern Power)... that by the looks of it on Google is actually rail-served (active?). The company website indicates they've been in business since the 70s. There were no other significant component mfgrs in northern New England and, interestingly, the report had estimates on job POTENTIAL created by increased wind manufacturing in the future, by state. NH - 1900; VT - 490; ME - 379. They based this on existing businesses that likely COULD make components. I would think that northern NE's best opps in this area would be limited to small sub-components.
