This might help you a bit for now. My colleague is still not here and I am not sure how Alberta is billed with PF like whether they consider any ratio or just unity pf in the grid. I will get the info from him and confirm the ratio.

That sounds like its only applied to commercial use, being billed based on kVA and not kW.

I am still confused about those components. Will get to you with the right stuff.

Electric companies will not be able to determine individual PF of all the devices and hence, even if they use any PF it is going to be an average of the whole house or just unity factor. I will get back to you after 12pm or something regarding this. My prof should be the best person to clear it up

Thanks let me know

I can't tell you how ****ed I'll be if this pump is actually costing me over 200W of power.

Easiest solution: move to DC motors. :P

I talked with a friend of mine from montreal and he said you are going to be billed for 1.85 * 115 * number of operating hours, theoretically. I will keep you updated

Well this is looking awesome, 65 Watt max stamped right on the $700 pump, meanwhile it's using over 200 Watts.

Hold on no need to get excited about it

I haven't confirmed it yet.
