There hasn't been much data reporting or electricity production going on at the UMPI wind turbine for the past few months. So we got a little restless and decided to visit the website of another 600 KW wind turbine - this one in Newburyport, MA.
Since the UMPI wind turbine just turned two years old, we thought it would make sense to look at two years of reported data from Newburyport. So we looked at the two year period, June 2009-May 2011.
As can be seen below, the Newburyport turbine performed at a capacity factor of 14.1% during this two year period. This is somewhat higher than the UMPI turbine's two year observed capacity factor of 10.6%.
On the other hand, one would expect that a turbine in Newburyport would produce more than a turbine in Presque Isle because it's windier in Newburyport.
As can also be seen below, Caribou, ME, which is near Presque Isle has a historical average wind speed that is only 81% of the historical average wind speed of Boston, which is near Newburyport.
It is refreshing to be able to see both the UMPI and Newburyport data as the wind industry obfuscates its production data under the guise of confidentiality. They make huge promises based on nameplate rating and make claims about powering "X" number of homes. But those are all just promises used to sell themselves to a trusting public. The reality is that the wind industry's turbines' capacity factors are very similar to what is observed at UMPI and Newburyport.
We know the turbines create tremendous negative impact. Such impact needs to be evaluated within the context of actual benefit, not industry-falsified grossly overstated electricity production figures.
