Nah you're forgetting the capital to build a proper 100kw warehouse. You cant just put AC in a room and call it a day.

Also you assumed avg mining hardware is 0.7w/GH. I would say its 1w/GH due to all the rush happened when 1TH/s miner came out.

Home mining has one advantage, once you setup a mining space ( dedicated room...etc), the mining expense is only the electricity fee. At 15cent/KwH, it would be on par with 100TH mining farm's expense per TH/s

It only make sense for MW mining farms from here. All the small mining farms will close shop b4 avg home miners. Take note noobs, dont jump into any group buy hash share deals.

Capital is capital, its not a running cost. But yeah, setting up a space for 100kW means about $5,000-15,000 in electrical work and cable runs, plus $2,000-20,000 for a cooling soluton (air cooling is the cheapest)

assuming 0.7W is fair i think, since the 1w/GH gear wil very soon be balanced with 0.5w/GH, and most manufacturers are now at 0.7w/gh. 

I would say that at this point in the game a 100TH farm in china (lower costs and wages) could be started up and over the salaries of two people while being profitable. In North America, you might need closer to 200TH due to the extra $15,000 year of a base salary and typically higher $/sqft for industrial space.


some basic math i did looks like 2 people with access to a suitable location costing $1200/month and needing $20,000 for setup  could distribute the cost across 4 years and pay themselves a small (~30k each) salary for a 100kW/100TH farm at a cost around $30/month  (a 2yr period is a cost around $50/month) Thats roughly equal to 0.05-0.08/kwh

@klondike_bar

thx man, then we can say that, $40-$75/TH/per month, is equal 0.0013$/GHS/DAY - 0.0025$/GHS/day , it seems pretty low for me..


and
@seriouscoin, what will be the estimated cost of 100KW and 1MW proper warehouse?


and, what will have to taken the efficiency of this mining farm, 85%, 90%?, i mean downtimes, pool failure, energy failure, hardware failure etc.

Hi, i wonder, what is the average maintenance cost of a mid or large scale of mining farm in the units of Wh/GHS? Can it be calculated?

maintenance cost = electricity usage of mining hardware + power supplies + electricity usage of cooling solutions(air conditioner etc) + rent of land + hosting internet + payments of staff + maintenance of hardware + etc..

could it be lower than 1W/GHS?

cost isnt represented in w/GH...

1000sqft facility with access to 100kW = $800-2000/month
internet = $100/month
2 guys who can spend average of 100hrs/month installs and maintenance = $2000-5000/month
using 0.7w/GH equipment, add 10% for PSU losses and 10% for air-cooling (no large farm would use closed AC) = <1w/GH = ~100TH capacity

so 100TH will cost 100kW + $2900-6000 per month.  ($3-$6/kw/month when distributed)
power in some locations suited for this is about $0.05-0.10/kwh or, or $35-$70/kw/month.

thus, a large location with well-priced power could have operation costs of $40-$75/TH/kW/month. In comparison mining at home with $0.15/kwh will cost about $105/month not including any rent/salary/internet/maintenance


EDIT: same math but for a 25kW capacity only would be about $50-$95/month
