Title: How many kWh are you using a month?
Post by: mike85123 on July 25, 2011, 05:57:32 PM
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" ;) 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 ;)

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 ;) 26.3 megawatthours

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

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

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.

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.

Post by: cicada on August 09, 2011, 02:53:49 PM
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

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...

Had 5Gh at the house running for a month and used 5998 kwh with the ac running 24/7. That bill was $600.

Recently moved everything for expansion and plan on using 17.75 kw per hour, 15,500 hwh / month not including ac. Just finished having 208v wired up. Looks like i'll be able to do upwards of 50 kw per hour soon at $0.07585 kw.     :o

Very nice.  $0.07585/Kw is very cheap.  I can't wait for winter rates.  I'll be at $0.104377/Kw during peak hours, but only $0.038162/Kw during off-peak.

I am using commercial "on demand" power which is meant for high Kw usage businesses. There are three charges:

Customer charge: $30
On Demand Charge: (highest Kw used in a 15 minute window within the month) x $8
Price per Kw: $0.07585

Since I won't have big spikes in usage, the demand charge is nominal. Also with this plan, the more power I use, the more I save.

My residential power is $0.11 for the first 1000Kw and $0.13 for every kilowatt after that.

I can also choose to go on the on peak, should and off peak rates which can vary from $0.03 to $0.11 but after looking at the numbers, there would not be significant savings unless i shut everything down during peak hours or setup some kind of backup system to run during those hours.

Btw, i'm in FL.

I'm boggling at the electric usage and the fact the police haven't kicked your doors in yet.
They seem to like spying on electric use and using it as probably cause. That is unless you don't live in a police state.

I'm surprised also.  I called the police and my power company when I started this.  Both were confused.  The police said that they have no way of knowing unless the power company turns me in.  The power company said that they aren't allowed to turn anyone in.  *shrug*.  Apparently I should have just started a pot farm a long time ago (joke).   ;D

so they bust down your door... then what? they'll see a bunch of video cards, and will have to pay for the door  :D. not like you're doing anything illegal with these

why would you call the police for "permission", and why would the electric company care about it (as long as they get your money)?

I didn't call for permission.  I called to find out whether or not someone was going to be kicking my door down at 2 in the morning.  I would like to avoid it.  I obviously wouldn't be guilty, but it would certainly be inconvenient.

bust down your door is the best you can hope for. Plenty of news articles about people being shot/killed family pets being killed over the wrong house.
A vet was recently gunned down in Arizona because one of the cops tripped going in the door and misfired. 57 bullets into the guy later..

Why in the hell in this day and age do they need 'meters' and a meter man anyway?  Can't the meter have a digital thing it it that sends the number to the power company and you can check to make sure THEY are not ripping YOU off?

I still don't get why some strange man has to come into your house to read the meter. Insanity.

Normally $250 last bill $550 so roughly $300 for seven rigs with sixteen video cards or ~$20 a card every two months the billing cycle around here paying 12.? cents kwh at the highest rate and like 8.? on the lowest.
Off topic.... How many coins a month does that generate?

19.5 Ghash/sec.

Very impressive. I had peak ~22ghash online in June, and had to pay way more ($2,400) during that time. Was forced to scale down a bit after the price drop.

Seems like electricity is a bargain where you live.

Yeah it is...

People talk about how cheap electricity is in Iceland.  Some parts of Idaho have electricity that is the same rate or cheaper (depending on the exchange rate).  Summers are hot, but we have pretty brutal winters too...  I'm certain that I can cool my cards with just a couple box fans when the temperature drops in a couple months.  I already do this at night.

With 5x 5850s in 3 rigs, I had my highest bill this month $271.16 @ 968kWh. It seems it's not anymore profitable for me to mine @ current exchange rate. Oh well, I can just pause mining a bit and wait for the prices to soar! :). But oh wait, is that even wise? Sheesh! Keep on mining! :)

I called my power company today after reading this thread and reading their published tariffs and rates (long document).  I will probably save money this way by switching from residential to commercial service.  I'm concerned about being in a residential area and asking for commercial service, but now awaiting a call from higher-up the customer service ladder about all my special power needs. 

My power bill will be about $900 (includes non-mining home electricity use) at my current rate and usage.  Getting about 12 Gh out of that.  So it looks like electricity eats about half my profit in mining even at $11 per coin  :-[

Commercial is definitely the way to go. I am saving upwards of 30% on the power bill now from residential and small business rates.

They want me to call the business solutions dept.  problem is the "small general" service is not to exceed 10 kw of demand, which I do exceed.  "primary general" requires a 12.5 kV or higher supply.  Mine is 240 V = .24 kV at 200 amps, so that is way out of my league.  I think I fit into the Large Municipal and School Service, but I'm just going to have to check with the power company...

Is anyone getting MORE than 240 V x 200 AMP to a single residential meter?

I'm using about 4700kW with my 8GH/s setup.

Has anyone thought about renting some space in a datacenter among a few users where electricity is the lowest cost?

Just a thought, I'm not sure how it could be handled operationally...

Just a thought, I'm not sure how it could be handled operationally...

I have spoken with multiple DCs and their biggest problem is the density of power and heat. At 16Kw an hour, they wanted to make me rent 10x the floor space, otherwise they would want me to pay for upgrades to the AC for the rack.

If you go with a normal host, they charge by the 20 amp drop at rates like $259 and that's at 120v which is uneconomical to say the least.

I would be willing to expand my warehouse cooling to accompany more rigs in the server room i have built. I can hold 30 rigs like the ones i have built. There would be upfront costs to upgrade the HVAC and power, but after than I would be willing to split costs (aka make minimal profit) as this would help me lower my overall costs to run the facility.

If multiple people went in, it could be quite advantageous for all parties.

Just curious what part of the country/world are you located?  I have though of renting some cheap warehouse space to expand my far (10GH/s is the limit of what my garage can handle in the summer) but I don't need a lot of space.  Lots of warehouse space near me but most are 5,000, 8,000, 20,000 sq feet which is just way overkill.

I am in Orlando, FL.

I have:

- 800 sqft warehouse with an office I will be using soon and a room with two big racks.
- Fully insulated server room that is 16ft by 9ft. approx 144sqft of space.
- 208v 200 amp three phase service @ .07585/Kw + customer charge, on demand fee and taxes
- 3 ton AC unit which can be upgraded
- security system with 24/7 monitoring of both unauthorized entry and smoke detection. Alarm utilizes wireless tech, it can't be cut off.
- Insurance on the contents of the building which can have additional riders added.

I will be using 18 of the 30 slots once I get some rma cards back.

Just curious what part of the country/world are you located?  I have though of renting some cheap warehouse space to expand my far (10GH/s is the limit of what my garage can handle in the summer) but I don't need a lot of space.  Lots of warehouse space near me but most are 5,000, 8,000, 20,000 sq feet which is just way overkill.

I am in Orlando, FL.

I have:

- 800 sqft warehouse with an office I will be using soon and a room with two big racks.
- Fully insulated server room that is 16ft by 9ft. approx 144sqft of space.
- 208v 200 amp three phase service @ .07585/Kw + customer charge, on demand fee and taxes
- 3 ton AC unit which can be upgraded
- security system with 24/7 monitoring of both unauthorized entry and smoke detection. Alarm utilizes wireless tech, it can't be cut off.
- Insurance on the contents of the building which can have additional riders added.

I will be using 18 of the 30 slots once I get some rma cards back.

What are your thoughts on the future of bitcoin?

I'm using about 4700kW with my 8GH/s setup.

Has anyone thought about renting some space in a datacenter among a few users where electricity is the lowest cost?

Just a thought, I'm not sure how it could be handled operationally...
You what?

I hope you got your SI units in a tangle there mate... that's going to be rather expensive and require a power station next door.

I've got around 7.5 GH/sec and I'm eating around 4 kW constantly. I'm just about to shut the whole shebang down to flash the BIOS of all the cards to undervolt the GPUs - I've been testing a lower core voltage for weeks now and it seems to work OK, so time to force it on the cards.

4700 kW is 4.7 megawatts. I'm having *real* trouble managing heat, and I'm in the UK and it's nearly November... if your rigs are dissipating megawatts then your house is going to catch fire.

Hee hee. Just taking the piss mate :)

But yeah, I've got a 4 figure electricity bill, so have just had EDF Energy turn up to replace my meter and put me on their 20/20 tariff, where half the day and all the weekend is a couple of pence cheaper per kWh. Should save me a hundred quid or so, and another along with the undervolting.

Datacentre rental would be great but my cheap AMD cards crash so damn regularly that I need physical access to reboot them every so often - there's only so much I can do...

 :) Was beginning to think this fella is abit stupid!! haha. What I wrote is ridiculous though - can you imagine if I was using around 5 megawatts and off single phase!!!!

I switched to the day night meter recently, it's going to save me a couple of hundred every billing cycle (two months here).

Well the idea behind locating many machines together would be that it wouldn't be a normal datacentre - it would be one of us - a bitcoiner! As suggested by gigavps if many people got together and we had a warehouse rental it's possible costs could be reduced...at least worthwhile looking into....like a co operative type setup.....mining pools taken a step further.....

Ideally a location could be selected where the cheapest power is available. Decent stable rigs would be a requirement to house but you would probably need a full time admin there never the less.

I'm surprised also.  I called the police and my power company when I started this.  Both were confused.  The police said that they have no way of knowing unless the power company turns me in.  The power company said that they aren't allowed to turn anyone in.  *shrug*.  Apparently I should have just started a pot farm a long time ago (joke).   ;D


I had to shut down some space in my grow op to make room for rigs.  *sighs*  MJ aint what it used to be with all the bath salts going around...

 ;)

I don't know how the 'land of the free' got like that... but whilst I'm not comfortable with the cost of electricity here in England, and do envy some of the commercial rates available in the USA...

...there's no way on Earth I'd swap my high energy costs for a society where using a significantly larger amount of electricity than your immediate neighbours could result in armed thugs breaking into your home, trashing your front door and killing you if you make the slightest 'incorrect' protest. FFS - and if that anecdote about the 'clumsy cop' was true, then thats truly shocking.

Don't want to get this political, but FFS, that's totalitarian, and beyond all credible 'appropriate reaction'. Regardless of my point of view re: legality of recreational psychoactives, breaking into someone's home with an armed troop needs *serious* justification and judicial oversight. This story is just plain Orwellian.

What's the situation in Texas? IIRC, you're allowed to defend your home and family in Texas, and you're allowed to own decent firearms. If this is the case, and I was a Texan who had his front door kicked off its hinges and a bunch of guys breaking in, I'd be shooting before asking to see their police ID. Would that make me a 'cop killer' and up for the death penalty? Or do cops in Texas behave with more common sense?

FFS. Growing pot plants. What a load of bullshit. If it weren't for crap like this then there wouldn't be so many people poisoning themselves with *hypothetically* similarly-acting 'research chemicals' made at below industrial-grade purity by cheapest-bidder chemical engineering shops in China. So many things are so fucked up the most basic level, it's untrue...  >:(

(rant off - sorry)

Hehe, loved that.

Being from Texas I can say that the situation regarding domicile search warrants is the same as in most places in the US. 
Typically, police announce themselves prior to entering, but in drug raids they do not announce and break in with a bang.  Only do they announce themselves immediately after crossing the threshold.

If you started shooting and killed some cops as they entered, and you miraculously did not die in the process, you would be charged with murder.

But you are correct in that you can kill someone in your domicile IF they 1) are trespassing and 2) are carrying a weapon.  IIRC the govt's position derives from the Castle Doctrine.  Technically the property owner should have to prove that he/she was in imminent danger of bodily harm.  If the trespasser is carrying a weapon the courts typically decide in the property owner's favor.  If it's a cop with a warrant you die or go to jail for a long time.

In other trespass circumstances across the US the law on killing trespassers can vary.  If you are unlucky and unable to show imminent danger of bodily harm you would most likely be charged with 3rd degree murder.  If the trespasser survives then assault w/ deadly weapon and attempted murder.  Though jurys have decided in property owner's favor in a number of cases.

Wisconsin is considering a law that would exempt property owner from liability for any injury caused to a trespasser.  This potentially means that harm or death through passive means (trap) or active means would  not result in a charge.
