Gotcha - looks like you guys have stepped rates at a threshhold of 1350 kWh/2 months. I'll put something together...

Okay, open up a blank Excel spreadsheet. Leave A1 blank.

Paste this into B1:
Code:
=IF(A1*730.5/1000>675,(45.9+((A1*730.5/1000-675)*0.1019)),A1*730.5/1000*0.068)
Then, just enter whatever your AC wattage is into A1, and B1 will show you the average hydro cost per month for running the dedicated equipment. This formula takes leap years into account.

Wow I didn't see any of these posts when I clicked on the new posts tab I just checked and seen all the replys after my last post lol.
ok I am a total noob with excel I actually loaded this up in libre office which should the the same thing.
as for this energy monitor the only one I could find was at Canadian tire and it is a hampton energy monitor and I have no real idea on how to use this thing lol

What's it called? Is it online?

Oh my. Quite interesting and nicely done. And for (Hydro-)Quebec, that formula would be?

Blue Planet Electronic Energy Meter. I don't know if it's online.

I'm pretty sure that HomeDepot and Rona will have energy meters as well.

Here you go. Leave A1 blank, paste this into B1:

Code:
=IF(A1*24/1000>30,(48.57825+((A1*730.5/1000-913.125)*0.0751)),A1*730.5/1000*0.0532)
I should probably note a key assumption I am making with my stepped rate formulas: that a dedicated rig gets to enjoy 100% of the lower pre-threshold rate. So take the Hydro BC and Quebec rates for example... the higher BC rates kick in after 1250 kWh over a two month period, while the higher Quebec rates kick in after 30 kWh per day. Since there is no way to control for the non-folding power consumption of each household and likewise no way to estimate whether the non-folding power consumption exceeds the stepped rate threshold on a household-by-household basis, I have no choice but to assume that folding dedicated rigs have first priority on power consumption.

Hypothetical example: 3.0's dedicated folding hardware runs at a daily average of 1000w AC while his entire household as a whole runs at an average of 1875w AC. These translate into 24 kWh and 45 kWh, respectively so he pays the lower rate on 30 kWh and the higher rate on 15 kWh. But because his folding dedicated consumption does not exceed 30 kWh on its own, my formula will estimate all of his folding power consumption at the lowest rate. This is obviously a questionable assumption since it's the non-folding consumption that should likely be considered the baseline, with dedicated folding consumption being an optional add-on amount that really ought to be taken into consideration afterwards. But like I said, it is impossible to control for the amount of non-folding power consumption on a household-by-household basis, so the only way to deal with it is to remove it from the equation completely.

crap I never thought of it that way.
hmm I wonder if I were to see if there is a bill from back in dec or jan when I was folding then could figure out a base from that because this place the only things on in this small place is the standard fridge stove sometimes elect heat ( which i never turn on ) older tv maybe 5 hrs max a day my folding box and main OC .

I actually never calculated (even roughly) the cost of folding. Quite interesting. Thanks a bunch Mr. Dead Things, very much appreciated.

And I've never really looked at the rates in other jurisdictions before. Toronto Hydro rates are pretty good compared to most, but I could save $160 a year if I lived in Quebec. That's about enough for a new OCZ Vertex 3 Max IOPS 240GB SSD!
