May Production Update

Damn.  I wanted to pass the 10,000,000 kWh mark at the end of May for the 7 months begining Nov 1, 2006.  I like round numbers.  The wind farm missed it by 12,000 kWh.  The wind died in the last day or two of May.Of course we long since blew past 10,000,000, as I am writing this on June 6.  12,000 kWh in 5 days is a breeze.

The wind farm produced 983,221 kWh in May.  This was its second lowest month since November, which was the lowest month since three turbines were in operation.  I expect the summer months will drop off further.  The capacity factor was 26%.

There was considerable maintenance outage in May.  All three turbines had their 6 month service/safety check, which takes about 2 days each.  A new revenue meter was installed to measure the output of the original turbine, as the output of this turbine is to be sold under the Standard Offer Program, and separate metering is a requirement.  The output of the new turbines is going to Bullfrog.  The whole wind farm was down for about 6 hours to install the meter.  And the original turbine had a few minor service outages during high winds.

The wind farm produced power about 75% of the time.  It produced at its maximum rated capacity only about 3% of the time.  So May often had wind, but it rarely had high wind.
The new turbines outperformed the original turbine by a wide margin, producing 347,000 kWh each, compared to 286,000 kWh for the original V80.  The V82’s have outperformed the V80 every month but one, which is what is expected.  They have 5% more swept area, which means they generally produce more energy over the course of a month.  Of course turbine availability can make a difference in production too.

Interestingly, it seems like it was quite windy for May.  The 286,000 kWh output of the original V80, which has been operating since November 2002, was the second highest for the month of May since it started.

I had to go to Toronto early yesterday morning.  When I left Lion’s Head, it was cold – about 12 or 13 degrees, and very windy.  We had rain in the night.  When I was just south of Wiarton, it was raining quite hard.  As I drove through Grey Highlands, the wind was just picking up, it was foggy, and and very sticky and warm.  And by the time I drove through Caledon, it was hot, and smoggy.  Down in the city, it was insufferable, as it often is.

By the end of the day in Toronto, it had cooled down to about 15 degrees in the city, and was very windy.  It was a classic cold front that took most of the day to move down from the Bruce to Toronto.  It cleared the air.  And along the way, it would have activated wind turbines at high output for 15 hours, as it did in Lion’s Head, as the front passed.  But of course it didn’t happen.  After Lion’s Head, there is only one place with turbines – Shelburne.  So instead of generating clean power from the wind, we kept the coal fired plants on, contributing to the bad air in the City.  Wind Power could have eliminated emissions on June 5 from coal fired plants if enough wind capacity was installed in the right place.

Maybe next June 5.  Or the one after that.
