I'm working on a project where we want to figure out how many hours a
year the building demand (KW) falls within given ranges (0-10KW,
10-20KW, 20-30KW, etc).
Is there an output report that shows this that I'm just not finding?
I set up a natural gas generator, and based on the output of this
generator, I can tell what part load ranges the equipment runs in, and
from this I can get a decent idea. But in order to breakdown the ranges
into small enough increments (10KW), I end up having to set up multiple
generators with load management schemes, but the numbers just aren't
really making sense.
Attached is a jpeg of the current load profile. I understand that there
is a peak near the 200 KW range - this is where the after-hours loads
settle at, and it is understandable for thousands of hours to be in this
range. What I don't understand is why there are two peaks at 420 KW and
620 KW, and almost no hours in between. I think it has something to do
with the generators, and how eQuest calculates the hours within a given
part load range, particularly when the 1st generator is at full load and
the 2nd incremental generator kicks on (I have the loads set to NOT
prorate).
I think it would be much more precise to be able to see the KW demand
for the main EM1 meter. Is that possible?
Thanks!
