Vikram and Jason,

I had a similar electric rate structure on a past project.  I used a rate
schedule with each block having a flag value.  For example, in the schedule
below, first 200 hours would be block 1 (flag value = 1), next 200 hours
would be block 2 (flag value = 2), next 200 hours would be block 3 (flag
value = 3), over 600 hours would be block 4 (flag value = 4).  A 24/7 day =
"flag value" is needed for each block with a corresponding Week schedule.
The annual schedule would then break down each month as follows :

for any given month:
day 1 to day 8 Week 1 (200 hours/24 hours/day = 8.3 days, rounded to 8)
day 9 to day 17 Week 2 (400 hours/24 hours/day = 16.7 days, rounded to 17)
day 18 to day 25 Week 3 (600 hours/24 hours/day = 25 days)
day 26 to end of month Week 4

Setting up the annual schedule can get tedious but seemed to work when
checking by hand in the ES-E DOE2 report file.  The DOE2 help files
concerning utility rates have an example of how to use the flagged rate
schedule.

Be careful of the KWH/KW-LIMITSUM blocks - I have only had luck getting the
limitsum to work when the schedule reads "first 200 kwh/ billing kW" not
when limit is based on hours.

Good Luck,

Vikram, personally I'd just get the hourly data and
dump it into a spreadsheet.  Keith Emerson
