Just got my first substantial electricity bill as a result of BTC mining... Just curious what kind of electricity bills other miners are getting.

This is for about 3 weeks of mining at around 5/8 of what I am mining now. Before BTC mining, in the summer months I was getting bills for 900-1000 kWh.

Total kWh used 3,233 at a total cost of $400.

Will have my first FULL bill in 2 weeks and will report back then.

What's your $ per kWh?
My property uses over 11,000 or more in the summer so you can imagine. Mind you we have 4 A/C units and multiple refrigerators.

Well, some basic maths that I had to run - in the middle of setting up a "small mining operation" Wink Had a talk today with the power company about my requirements in the not too low 2 digit megawatt per month area.

Every month has on average 730.5 hours. This is based on 12 months per year, 365.25 days per year. Yes, there is a leap yearevery 4 - lets just keep it like that.

Thus, every kilowatt you draw are 730.5 kilowatt hours per month Wink

Test rig here uses around 1.5 kilowatt for 6 x 6970. This means 1.09575 megawatt (1 point - decimal there). I round that up to 1.1 megawatt to account for side power.

A halfrack has 8 computers, we go for 3 half racks at the start Wink 26.3 megawatthours

Sounds like a lot, but at the end there is this hugh multiplicator from hours to month.

Wink Btw, I got contractually the ok to draw 365.25 megawatthours (500kw) from that location, more 6 months after reaching 300kw Wink

The power co says generation is like 7.65 cents but that doesn't cover transmission. Based on my last few months bills, after all of the transmission, generation, fees I am paying 12.2ish cents per kWh.

A 750W running 100% 24 hours is 12 cents is about $2.16 a day just to give you an idea. The idea there is the 24 hours , you'll probably be up 90-95% due to different variables.

How much of your 11,000 kWh is attributable to BTC Mining?

Not much at all but I do live in the South and with the current temperatures the A/C units alone eat I think 10,000 watts while my rig is running with 1000 watts. So yea it is this miserable weather we are having.  I actually prefer the rain since the weather is cooler outside and the a/c has to work less.

A 18,500 BTU Window AC draws 1800Watts from the plug. What kind of AC unit do you have which draws 10,000W?

Looking to review Bitcoin / Crypto mining Hardware.

You shouldn't interchange megawatt and 1000 KwH.  Megawatt is a measure of power, kilowatt hours are measures of energy.

They are not window units, it is central air and with more than one unit.

I di not. I said MegaWattHours - which obviously is 1000 kwh.

Just got my 2nd power bill...  this one is for a full months worth of mining.

5,992 kWh for a total cost of $741.14.

I'd like to see what everyone else's electricity bills are looking like. Post your latest.

Don't have an exact bill to read, but back-of-the-napkin estimates:

1,692kWh for ~ $292 / mo @ $0.174/kWh

Most of the hot air from my rigs is vented outside so the AC cost isn't huge.

[edit] that's just my rigs, I usually have ~$100 on top of that for normal household use.

The bill I have due next week was right under 5,000 KWH for 4 dedicated miners and 2 other desktops w\ a single card in each. 

I'm guessing my normal usage outside of miners is probably 1200kwh.  Total bill is $600

I told her, 'i really want to see what happens when the meter rolls past 99999'

34752 and counting..

Last month was $1,023.43 for 7,408kwh.  This month was $1585.67 for 11,140kwh.  I'm having a "time of day" meter installed so that the electricity used at night is half of the cost...
