[Equest-users] Electric Block Rate based on monthly demand

Attached is a sample rate based on PECO in Philadelphia.

It's slightly different in there are no sub-tranches within each kW/kWh block.
Thus, the first 150 hours of billed demand are all billed at one constant $/kWh, the second are at a different constant $/kWh, etc.

I also used to use spreadsheets. If you decide you have to, I'm pretty sure there is an automated procedure for extracting monthly demand and usage it out of the *.csv files generated automatically after a model run. Let me know if you want me to dig that up.

Sounds like a Sothern Company or TVA rate plan. You can do this in eQUEST  - I think you need to do this in the detailed interface using the kWh/kW limitsum option. If I am not mistaken - in the kWk/kW limitsum option you set the limit for each block as the ratio of kWh/kW (i.e your limit for the first block is 125, 275 for the next, and 999999 for the third). You need to set your block up as incremental (not cumulative). In each block you will set up your rate tiers with the same limit (125 for all the first block tiers, 275 for all the second block tiers, and 999999 for all the third block tiers.)

Let me know if this works for you

I have a utility rate that has blocks based on the kWh/kW for each month rather than strictly kWh usage (see below).  I did not see a way in eQuest to input this type of rate in the detailed edit mode.  Has anyone ever dealt with a rate like this in eQuest or have any suggestions?  I have a spreadsheet set up to calculate the costs but I hate having to figure out the monthly peak kW and input to the spreadsheet for every model iteration.
