Seems to be the 100TH IPO that founded MegaBigPower?

https://bitcointalksearch.org/topic/m.4412552

on 9th Jan 45% of cex.io total hashrate was there in Ukraine

hoping you all can extrapolate the needed facts

very true. unfortunately peta has not yet provided any information about power capacity
I know they work with solar power. a data-centre in brussels is certainly not the best choice, maybe siberia or kuwait or similar is better choice. The assumption is majority of units will be based on A1 chip and so there you can extrapolate the capacity from 500TH of A1 based on their power efficiency. Coincraft desk is ~400W afaik at 1TH, supposedly rigs come in at 3000W for 2.8TH

Thanks, good find.

What's that in kW?

30 TerraMiner IV: 60kW
70 Coincraft Desks: kW
165 CoinCraft Rigs: kW
250 TH of custom boards: kW

The power is the only thing that wont change. hashing power will change all the time.
 
Facilities are measured in power, not hashrate.

The HK facility was stated as 500kW several times. Also on the youtube video.
In Friedcat's early updates about the original farm he spoke about 0.5MW approval:

No idea on the satellite clusters though. That's all  old stuff, so to speak.

PETA mine

http://www.peta-mine.co/
Location: Brussels, Belgium

currently at 108TH

(30 Cointerra TerraMiner IV, 70 CoinCraft Desks)

165 CoinCraft Rigs along with 250 TH of custom board forthcoming
each datacentre unit support up to 500TH.

Where did you see that each AM farm is 500KW?

Thanks for the infos, I 've updated the original post. Still all very early, but we are getting there.

Would be great to have more info on these two and the original AM farms. I am going to send a couple of PMs.

Don't forget cloud hashing in Iceland:

200kW for the average miner and/or enthusiast? Absolutely.

200kW for a data center? Heck no.

We're running ~17kW, and we're pushing the limits on what we have available. I would love to be able to pump out 100kW or more.

Gigavps showed 108 Ant Miners recently = 20TH

BioInfoBank 100TH-mine project this might be the same as MegaBigPower. They claim to have power costs of only 0.024 USD per kWh!

I suspect anyone who makes mining hardware probably also owns a farm... er... I mean customer hosting facility, obviously!

It looks like gigavps is running ~116TH.

Do you really think 200kW is a lot? I currently have a 200 Amp breaker in my house, and use 100 Amps just for mining with 240V outlets, which puts my mining capacity at ~19kW (100 Amps * .8 * 240V = 19200 Watts).

I'm debating adding cooling and an additional 200 Amp breaker just for mining. That would increase my mining capacity to ~57kW (300 Amps * .8 * 240V = 57,600 Watts), and this is just in the basement of one residential house.

Granted, this setup will require a lot of expensive cooling in the Summer, and some of the extra power will need to go towards cooling, but I'm comparing those costs versus the cost of data center hosting. Data center hosting is expensive, and my electricity is relatively cheap at 12 cents per kilowatt hour. It's also nice to just be able to go down in the basement and deal with any issues should they arise.

After an electricity and cooling upgrade, I can realistically run ~50TH in my house using equipment that uses 1W/GH. I suspect miners will be available in Q3 of this year that will only use .5W/GH, thus increasing my max capacity to 100TH.

Being able to afford 50-100TH worth of mining equipment is another issue altogether, but it's not that difficult or expensive to upgrade most residential houses from 200 amp service to 400 amp service and use 240V outlets for mining.  

Hmm... Iceland is known to be cheap when it comes to power..?

I got quoted once for a full 1kw power, cooling and i think it was 4u for 75€ a month - including i think it was 1tb of data traffic..

is that expensive?

Power costs for iceland will be high, as its either geothermal or imported gas.

I am a bit puzzled why theres non of the really big farms on Iceland..

Yeah, ONLY 200kW. 

A comment on the above mention of using traditional data centres to host Bitcoin miners.

Putting Bitcoin miners into traditional data centres is not going to be cost effective unless you can get some really unusually deal - for example use of a disaster recovery data centre subject to no disaster occurring.

A traditional data centre is always going to be expensive. It is set up to provide very stable and reliable power and air conditioning.  Bitcoin mining does not require this level of environment. 

The UPS and generators in a traditional data centre are not needed and are just a wasted cost. It does not greatly matter to Bitcoin mining if a power outage takes mining down for a couple of hours each 6 months.

Most of the air conditioning can also go. The tight temperature and humidity requirements of hard disks are not relevant to bitcoin mining.

All bitcoin mining needs is very cheap power and a rough and ready way to remove lots of heat. 

I would suggest the only large scale way to go is to find a secure warehouse area with lots of cheap power.  Its even better if it is a cold location allowing easy air cooling.  That way you can get away with simple air conditioning.   Alternatively large scale mining can use immersion cooling.

In summary the traditional data centre is not the way to go for large scale mining.

That's only 100-200kw isnt it?

Eligius is down now so I forget the exact hashrate, but according to the top miners stats he is running over 100TH.

I wonder how long it will take for the "MegaBigPower" cluster to get ROI
