The UMPI wind turbine has a capacity of 600 kw, or 14,400 kwH per day in perfect wind.  Today the website reports 345,400 kwH "since mid-November".  That's 190 days, and the power that was produced averaged 1818 kwH per day. Divide 1818 by 14,400 and you get a 12.6 %  Capacity Factor. For this turbine in this location, 12.6%  Capacity Factor is about average.  On the 14th of this month, the turbine's third anniversary, I calculated a Capacity Factor of 8.9%, including a 210-day period of…

Today my wife and I were at our camp, which is on the hill across Upper Hot Brook Lake from the dozens of Stetson I and II turbines. There was a good wind all afternoon, with some whitecaps on the lake. When we  arrived at about 12:30 pm, ten of the eleven visible Stetson II turbines were turning, at about 23 rpm.  Later in the afternoon (down at the lake) we saw only Stetson II turning, and at 3:00 to 4:30 none of the 30 visible turbines, including all of Stetson II and about 17 of Stetson…

The quarterly summary and spreadsheet pages of the FERC website are shut down as of 11:00 this morning (5/14).  I am hoping this means they are being updated with 1st quarter 2012 data. (The quarter ended March 31, 44 days ago.) 

  Also, the UMPI turbine was erected exactly 3 years ago.  I plan to do a summary of its power production , capacity factor, and reliability record and I will post it soon.

  One sentence was changed on the website: a re-wording of the explanation of…

The UMPI website has posted the turbine's power output for the past week, Friday May 4 - Friday May 11:  12,324 KWh was generated by its 600 kw turbine in tha past week.  12,324 KWh divided by the 100,800 KWh per week installed capacity (600 KW X 7 days X 24 hours ) gives a Capacity Factor of 12.2 %,  slightly less than than the average 12.7 CF for the previous 164 days. Before mid-November, it was non-operative for 164 continuous days. 

I am hoping UMPI will continue posting a weekly…

  The Mark Richey Woodworking Co in Newburyport, MA put up a 600 KW turbine at its plant in March  of 2009, accompanied by much publicity, etc.   It is the same size (600 KW) and manufacturer as UMPI's turbine, which went up two months later in the same year.  There is a website that reports steadily on the Mark Richey Co. turbine's output;  UMPI's website reports sporatically, at best.

Google:  Mark Richey Woodworking.

   As far as I know the Mark Richey's Co's turbine has not…

I figure a 3-year13.4% Capacity Factor for the Mark Richey Woodworking Co's turbine, which is identical to UMPI's. They both went into use three years ago.  The M. Richey Co.'s turbine and website are much more reliable than UMPI's, and Newburyport is on the MA coast, not inland. Nevertheless.....

The UMPI turbine site has just posted a new power production figure::

Since mid-November of 2011, the turbine produced 302,150 kWh for UMPI.  

That's 164 days, an average of 1,842 kWh per day.

302,150 kWh divided by 164 gives an average of 1,842 kwh per day produced since it was fixed.  

It is a 600 kw turbine; 600 kw X 24 hours is 14,400 kWh per day "installed capacity".  

1,842 kWh (recorded average daily power production) divided by 14,400 kWh (installed…
