Re: Consumption for for GE1.5

Mark Eilers, Fisher and Ratekin:

Mark Ratekin has in his possession an IEC standard power curve for the
Tehachapi 1.5 Turbine. This power curve shows both the power produced and the
power cunsumed below cut in wind speeds. The consumed power can be binned
just like the production curve to produce a "energy consumed" for any given
wind site.

Perhaps Mark Ratekin can forward this curve to Mark Fisher for this type of
analysis.

Mark,

Will they be using some method of separating power going into turbine from
power coming out of the turbine? And would it be done on a turbine by turbine
basis or would they measure at the substation? And do you know what period
they would be using for measurement (10 minutes, hourly, daily, etc.)?
Clarifying these might make it easier to determine what we might be able to
figure out.

The VisuPro data collection has a consumption counter as well as a production
counter (energy, i.e. kWh). However, both counters are net counters, so for a
measurement period either one or the other will increment [or possibly
neither] (VisuPro is currently set to use a 5.5 minute measurement period).
Since the counters are net counters we don't really know the true consumption.

In a discussion between Hollis and Kevin, it was suggested that the way to
know what the parasitic load was would be to put instruments on a turbine and
measure what the load actually is. For further information on this you might
contact Kevin.

Hope this helps.

Is there any way to get an idea what we are seeing for parasitic demand for
our large projects in TX as a more representative number. Let me know.

Gentlemen

I need to know the power consumption level for the GE1.5, non cold weather.
I heard 40kW which seems too high for the non-CWL or CWE. It is also my
understanding that the Eickhoff GB did not need to have the 35kW for
lubercation (backup power issue).

FPL is wanting to know the outcome of this issue so they can determine their
demand charges. Just so you know, the New Mexico project (200 mW) has a
demand charge of $6/kW/mth so; 136 units * 40kW * $6 = $32,640/mth or
$391,680/yr in demand charges.
