Frustration with demand billing in eQuest

I'm having an issue that I can't seem to figure out. Although the easy
solution would be to explain the discrepancy and subtract out, I would
really like eQuest to model this properly.

We have a utility that bills based on demand, and I've set up two
schedules for the two seasonal rates. See below. Last time I
checked, May has 31 days and September has 30. However, what's
happening is that I'm getting double billed for demand in the two months
(May and Sept) where the switch occurs.

See the screenshots further down.

Has anyone ever seen this, and do you know how to fix it?

The issue is exacerbated by the fact that the rate schedule has a
minimum demand per month of 75% of the maximum from the previous 11
months, so I have a min charge set up of 1049 KW.

Why is some of the energy as shown in the ES-F report allowed to creep
over into the next billing season?

I've tried messing with the demand billing windows (15 mins up to 120
mins), the fixed vs sliding scale, etc, but nothing changes the fact
that SOME energy creeps into the next season. Help!!

(PS - changing the month/day of the schedule from 5/31 to 6/1 does
nothing).

Hi James,

Other than hearing your frustration, I can do little else with this level of
information. I would guess, and I might be wrong, that this is not a bug. I
would guess that you entered some conflicting information somehow,
somewhere. Do you read BDL? If you do, I would start looking about in your
.inp file. Look at schedules, first. Then look at the economics inputs. If
you want to send us a Window's XP compatible copy of your .inp file some of
us might take the time to look around in it for you, too.

Keep the faith,

Carol
