Thank you for your reply.

While putting up a residential sized wind turbine is do-able I would prefer to do this as a money-making business.  100,000 kwh - and I know that means annual production - is what is required to make the "math" work, ROI, income stream, & all that.  

BTW, I need to be concerned about peak wind speed as I'd just as soon not have the tower crashing down on one of the structures 'round here, the turbine ripping off the top of the tower and flying away, etc., etc.  

Being a Designated Cynic isn't merely my job, it's my passion.

H'mm.  Let me try and recast my question.

My requirements, at the money I can afford to throw at the situation, are larger than the normal "residential" market and way too small for the serious players.  Before I put a lot of personal time - of which I have little free - I need to find out if there is a reputable manufacturer with a reliable product in my (admittedly minuscule)  market niche.

1.  Until you have some idea of your wind resource, you have no idea of how much swept area (watts/m2) you need to produce 100,000 kwh/yr.  Once again, you can bet that UNM and the local dealers have a handle on the wind resource, which is your first step.  Click here for larger

As you can see, NM basically has strong ridgelines, and little else.  This is why certain areas already have windparks, as in the Guadalupe Mtns.  Hardly anywhere has over 500 w/m2.  (Compare to Scotland with much over 700w/m2)


This map indicates that New Mexico has wind resources consistent with utility-scale production. The largest contiguous area of good-to-excellent resource is in central New Mexico between Albuquerque and Clovis. Other notable areas of good-to-excellent resource are located near the Guadalupe Mountains in southern New Mexico, near Tucumcari, and in the northeastern part of the state near the Colorado and Oklahoma borders.

They are not talking about residential here.  It's highly likely that you will need to put the turbine at the loneliest ranch high up halfway to Roswell, and pay the owner something, before you can get anywhere close to 100,000 kwh.yr.

No, you don't need to be concerned about peak wind speed, unless you have strong hurricane winds a few hours a day, in which case you don't live where you live.  Certified turbine tower combinations are designed to survive 150 mph winds, and be able to return to power production after 120.

I already gave you two very reputable manufacturers of different scale, and local dealerships, which you didn't acknowledge.  If you need a larger turbine, the strongest turbine in the world comes from Northern Power Systems, and operates well in polar regions or at microwave repeater stations high in the Canadian Rockies with maintenance necessary only when the repeater station is visited. But they are expensive of course.

Being a Designated Cynic doesn't absolve you from doing your own homework.  And how does "getting the math to work" work if you need to keep investing in larger and larger swept area to get your 100,000 kwh per year?

There was a company taking down old DoE turbines and refurbishing them and selling them (apparently the space is now valuable enough that it is worth taking down the old units for newer larger models).
