"INSTALLED CAPACITY" IS A JOKE

  The term "installed capacity" refers to the amount of power an industrial wind facility would produce under ideal wind conditions; but such ideal wind conditions rarely (if ever) occur.    

  Wind Farm Proposal and Permits usually refer to the ratio of actual power to be produced compared to this production ideal as "an expected capacity…

UMPI summer months - power actually generated

According to its public website, the UMPI turbine generated 63873 kWh in June, July, and August 2013. Its installed capacity is 600 kilowatts, or 14,400 kWh per day;  it actually  averaged only 701.9 kWh per day, a Capacity Factor .051. This is 1/20 of its installed capacity, or 1 hour and 10 minutes of good wind per day.

   If your mind shuts down in such a blizzard of figures, you are at the mercy of the wind promoters. You…

UMPI turbine in doldrums

  The UMPI turbine had pretty poor wind for the first ten days of June. It generated just 11,621 kWh. If there was a perfect wind, if would generate 14,400 kWh in just one day (600 kW X 24  hrs)!

  But the wind lately has been far from perfect; in fact, the UMPI turbine actually consumed grid power on June 7 (-10 kWh) and June 9  (-8 kWh).     …

Right on, Gov.

The Governor is right, and Brad Blake is right.  Maine does not need wind power, and never did. Kudos to our Governor for recognizing this. The existing wind farms' 2013 power production was a mere 24.72% of capacity. It's not worth it.

UMPI turbine working again

The UMPI turbine is working again (according to its website) after about 2.5 days of non-reporting.  During that time it generated about 800 kWh of power.  At 6:00 pm  2/15 it is in the middle of a snow squall, according to the live webcam.

UMPI turbine real output

Facts about wind turbines' actual power production are difficult to find, but University of Maine at Presque Isle (UMPI) is the exception.

Accompanied by much publicity, in May 2009 UMPI purchased and erected a 600 kW Bergey turbine rignt on the campus. It  came on line in July 2009 with promises to make information available to the public through a website, using a new "first of its kind" reporting program. The program took…

UMPI turbine website is working- again.

While the  UMPI turbine "live wind data" website was down 1/19-1/22 the turbine itself apparently kept working, at a Capacity Factor  .188.

UMPI turbine nowhas a webcam

The UMPI turbine website now has a webcam which shows the actual turbine, with a  new image about 45 times a minute.   So, if you are wondering if it is turning, you can look and see.  It is barely visible at night, but very clear in the day time. Google "UMPI Turbine" and click on the new little box on the home page. Thank you UMPI.  Standard working speed of the blades is 28.5 rpm.

UMPI turbine ten day capacity factor

Capacity Factor (CF) is a standard and meaningful way of measuring a generator's actual power production over a period of time.   The UMPI wind turbine has an installed capacity of 600 kW, which means in a full day with perfect wind it will generate 14,4OO kWh. 

   Northern Maine has just experienced a notably calm 10-day period, November 14-23,  and the UMPI turbine website reports net power…

UMPI turbine website updates frequently if downloaded in Google Chrome

If you use download Google Chrome to look at the UMPI turbine website, you will see the wind speed, rotor rpm, and generator rpm data changing every ten seconds. The wind is very changeable.

UMPI turbine ten-second power finally reported as promised -VERY SKITTERY!

Three years ago  UMPI promised the public a turbine website that would report its output in ten-second intervals.  Today I noticed (for the first time) that the software for that function is ACTUALLY WORKING!

For five minutes, at 10;25 am today (11/12/12)  I watched wind speed and power changing  every ten seconds, and I wrote the changes down as fast as I could: (wind speed in mph/power produced in kW) 12mph/86kW; 14/117; 12/69; 12/72; 11/91; 13/91....... I think that represents one…

UMPI TURBINE IS WORKING !

After a few hours of non-operation, the UMPI turbine is producing power again! In a 14.3 mph wind it is producing 307 kW, a bit more than half of its installed capacity. The next couple of days should be good for wind power, if it keeps working; a hurricane will be passing by.  In the past 32 hours it  generated about 6500 kWh; this is about 203 kwh per hour, or a .33 Capacity Factor. I will try to remember to report the post-hurricane capacity factor in a couple of…

UMPI TURBINE NOT WORKING -again

Not surprisingly, the UMPI turbine site indicates nothing but zeroes this morning, October  30th.  I presume this is superstorm Sandy's doing; high wind events have frequently preceeded this turbine's breakdowns.

UMPI turbine is working again.

After 17 days if non-operation the UMPI turbine site reports it is working again!  At 5;30 PM in an 11 mph wind it is generating 43.9 kW.  During the 17 no-operating days it consumed 41 kWh of grid power, an average of 3 kWh per day.

UMPI turbine seems to be working

The UMPI turbine seems to be working! At 4:00 pm today (9/26/12) the website reports rotor rpm at 18.1; generator rpm 28.6; power 354KW, and a 30-hour net gain of about 4500 KWH.  This is the largest net gain reported in months. The turbine's installed capacity is 600 KW, or 600X24H=14,400 KWH per day.  That's a Capacity Factor of .25 .

UMPI turbine website still working - sort of

The UMPI turbine is continuing its partial data reporting.  The wind speed seems to vary, and the rotor and generator rpm vary also, but the power being produced has been a steady minus figure for five days, usually 

- 0.1 KW. I check this daily. 

  Net power produced has dropped about 38 kwh in that time. "Power" reported was 25,122 KWH Sept. 19;…

UMPI Turbine is working, apparently

9/21/12 - UMPI turbine website reports it is ACTUALLY WORKIN , after 180 days.

As of 1:30 PM today, the "live turbine data" web page reports: wind at 7.6 mph, blade pitch at 2 degrees, rotor at 28.8 rpm, 25,000 kwh produced, generator temperature 21 C, power producrion minus 0.1kw, 412 Volts. The bar chart is unchanged and (not labled) it is about 17 months old. The power produced is a puzzle, since it gives no dates. The cute…

Hannah Pingree on the Maine expedited wind law

Hannah Pingree - Director of Maine's Office of Innovation and the Future

"Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine."

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/
