Wednesday, June 27, 2012 -The UMPI turbine website just posted a new production figure: 374,690 kWh since "mid-November".

That's 217 days, or an average of 1727 kWh per day.  The "installed capacity" is 14,400 kWh per day, so that's a Capacity Factor of  11.99%.  No other new information is posted - the "full turbine informaiton" software is still not working.

Today (July 20, 2012) the UMPI wind turbine site reported  actual power produced since mid-November of  2011 at 364,689 KWH. That's 210 days, and an average 1736 KWH per day. Divide that average by the "installed capacity" of 14,000 KWH per day and you get .124. This is called the "capacity factor"; capacity factor is seldom mentioned by wind promoters. It means the turbine has been working at one eighth  (12.6%) of its potential since it was repaired in mid-November of 2011.  This, for an…

Today the UMPI turbine website reports an update of its ouptut; it generated 355.286 KWH since mid November. That's about six months, or about 183 days. The turbine's "installed capacity" for that period is 600 KW times 24 hours times 183 days equals 2,635,200 KWH. Divide the installed capacity into the actual power produced yields a paltry Capacity Factor of .134 . The previous Capacity  Factor, on May 29 was .126. An optomist would say things are improving. I think a realist would say…

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…

  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…

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…

  The UMPI turbine website is reporting power production the past 140 days:  290,516 kWh "since mid-November" until April 6.  I calculate: 140 days at 600 Kw capacity and 24 hours per day comes to "installed capacity" of 20,160,000 kWh for that period; 290,516 kWh actual power production divided by the installed capacity gives a MINISCULE .014 Capacity Factor.  This compares very poorly to most Maine wind farms' CF, which range from .24 to .41 CF for the same period.

The site…

As of March 15 the UMPI turbine website reported the turbine, after a "down" period of months for repair,  had been generating power for 126 days;  "180,240 kWh since 2nd week of November".  There is no other information - the software needs "fine tuning",  

Operating perfectly in ideal wind  the UMPI turbine is "rated" to  generate 600 kW, or 14,400 kWh per day

 It has been in operation 126 days since early November. 

14,400 kwh X 126 = 1,814,400 kwh. This woud be 100%…

On a visit to the UMPI campus today (Jan. 22) the turbine was not moving at 1:00 PM.   It was turning at apparant full speed at 4:30 when we left. Whether it was producing power or not is a mystery. The turbine website does not have any recent information on it at all; the latest was the report of 94,620 KWH produced as of December 29.

The UMPI turbine is working! After 200 days of down time in 2011!  In tha past week some 17,000+ mWh were generated and sold to the grid, addording to the website..  Furthur work is ongoing, to get the site reporting all promised data.

Here is the full statement on the turbine's condition from the UMPI wind turbine website, posted about 9/17:

  "The general contractor conducted diagnostic and repair work on the wind turbine in mid-September and determined there is a broken shaft in the nacelle. Most of the shaft has been removed for furthur diagnostic work and the contractor is securing the appropriate replacement parts.  They hope to have the repairs completed in time for the approaching wind season."

UMPI reports that there appears to be a "broken shaft" on their iconic wind turbine. They hope to have a new one installed in time for the "approaching wind season". This is the first time I have seen a "wind season" mentioned. 

  The site has not reported any new data for about five months. First it was a "radius rod"; now the trouble

is a broken shaft. Also, the data reporting software has been down, and no power production figures have been posted since March.  The monthly…

UMPI  has finally posted March power production: 17564 KWH, or 566 KWH per day. The turbine's capacity  is

600 KW, or 600X24=14400 KWH per day.  This figures  as a 3.9%  capacity factor, or less than an hour per day of "good" wind. 

This sort of  "explanation" of the lack of other data has been posted for about 10 weeks::

    "The  Live  Wind Turbine Data is not currently active due to repairs. The general contractor anticipates

this system will be functional this…

 My self-imposed task of monitoring of the UMPI turbine website continues. The latest ten-day net power production for this 600 kW turbine averaged 935.7 kWh per day.  That's 6.6% of "rated capacity"! 

My casual log of rotor windspeeds shows the following  momentary data:  (Rotor-level wind speed in mph)  4.3; 2.5; calm; 7.8; 3.8; calm;14.5; 13.9; 7.4; 9.6; 5.1; calm, calm, calm, 3.1; 5.4; 3.4; 13.2; 10.5; 15.2; (one day I skipped; the next day, 2/08, the site reported all zeroes),…

Today is January 27. According to the website, the UMPI wind turbine produced a total of 22,200 kWh over the past ten days. Those days included a n'or'easter Friday the 21st and  yesterday the wind was essentially calm.  That's the way it goes with wind power. 

That  power output is an average of 2,220 KWh per day. So, with capacity of 600 kW, the turbine averaged less than four hours of good wind each day. 

Ideal wind whould produce 14,200 KWh - but it never happens. Thanks to…

I see Wind as a nursery crop for the next Nuclear renaissance.

DOE recently made public its plans for small nuclear reactors to help pump water for storage at Wind turbine sites, to allow more Wind in the mix.

The science on human contamination from radioactive materials makes it now extremely difficult for…

UMPI's 600 mw turbine reports an average power production of 2324.7 mwh the past ten days.

This is a little over five hours of good wind per day. The period included a 3-day nor'easter. Right now it is calm, agai,with power at munus .3 kw.

UMPI's turbine website reports power produced for the past ten days (10/02 thru 10/11) totaled 20192 kwh, or an average of 2019.2 kwh per day. This is better than usual; there has been some windy weather lately, for a change.

In the ten days 9/11 thru 9/20, the UMPI turbine produced only 688 kwh per day. The turbine's "capacity" (which wind turbines rarely if ever produce) is 600 kw, or more than 14,000 kwh per day (600 kW X 24hrs)

For the past ten days (9-11 to 9/20) the UMPI turbine produced an average of 688.4 KWH per day. This period included some of the hottest days on record - there was essentially no wind most of the time on Sept 11,12, 13, 14, or 15. If Presque Isle residents saw the blades turning, it was either just to look good or perhpas to keep the shaft from warping.
