[Equest-users] Real Time Pricing / 8760 Utility Rate

[Shea, Rebecca]

You know what, I was thinking that the ENERGY-CHG-SCH was just for demand for some reason, and that I didn't need it since I'm only tracking consumption right now.  I put my schedule in there and it seems to be acting correctly, (more reports will tell).  The EMIT (link below) made exporting an hourly schedule pretty easy since I had the RTP for 2010 in excel already.  For those of you creating 8760 schedules, definitely check it out.

 

I'm having an issue of getting it to switch rates in a parametric run.  I tried setting up both rates, assigning EM1 to the TOU rate in the baseline and RTP rate to EM1 in the parametric run , but in both cases it calculated the $$ using a sum of both rates.  I ended up creating 2 separate models to compare them, but if someone knows how to switch utility rates I'd love to hear.

There is a "Energy Charge Schedule" keyword (ENERGY-CHG -SCH) on the "Utility Rate Properties" dialog that accepts a schedule for hourly-use schedules, but as David notes that is a rather complex utility rate to model.  The help file says this about the keyword:

 

U-name of a SCHEDULE which specifies an ENERGY-CHG that varies by time of day, week and/or season. The units in the schedule should be $/UNIT. This schedule is used for all time-of-use energy billing (demand time-of-use billing is more complex, and requires the use of multiple BLOCK-CHARGEs). If both an ENERGY-CHG and ENERGY-CHG-SCH are defined, the values will add.

That's all it says on this keyword, too...so if your consumption and demand charges both are real-time pricing, there's quite a bit of work ahead of you.

Make an output report of the hourly building electricity consumption/demand values that you need and do it in excel.  Probably will be faster than making that complex of a schedule.

I know that the joy of eQuest is that if you can schedule it, you can do it.  However - can anyone give me a quick tutorial on how to assign an 8760 schedule as a utility rate?  I used the handy dandy "Energy Model Input Translator" put out by RMI to generate my schedule (http://www.rmi.org/rmi/ModelingTools) and then I imported the .inp file into eQuest very nicely... now what? J (I made it a "multiplier" schedule, not sure if that is correct, but I'm attaching it here.  I can easily change the schedule type if necessary)

 

As always, any help appreciated.  Thanks for your valuable time,

Beka Shea
