Question about power needs for a mining farm

Hey everyone, I’ve got a question about power needs for a mining setup. If I’m looking at a 3MW mining farm, what’s the typical transformer or power setup in the US?

You get the transformer from the power company, at least the places I know. Assuming the location can be serviced with such amount of power.

If you want that kind of power you would in most cases also get a specific contract with your power supplying company. You can't just simply hook up your miners with a standard household contract. In this contract it would also be specified that they deliver up to X amount of MW to your location and at what price. In some cases it could be that it is not getting cheaper the more energy you need. Maybe the infrastructure can only provide a specific amount at low cost.

As far as I know mining operations go where energy is cheap. One of the place in U.S which is Texas has some of the lowest kilowatt hour prices in America. But in terms of transformer they used, I had no idea what it is?

But they also have a rising anger about mining operations, because of the high power draw and also the loud noises that come form mining facilities. So you should also consider that you may be not extremely welcome if you want to build a large operation.

There is nothing to be angry about, its more customers for them and the large miners install their facilities in industrial zones where noise is allowed. This is the same as any other technological industrial activity like a data center. Only fools would ban this wealth creation activity, compared to other industries it is far more clean.

Apart from just getting the transformer from the power company he can also do well to get into an agreement with an electricity company (they could set up every requirement needed) on how much power they could supply to hi. It could be on a cost effective rate based on their MOU.

Finally got to this. 3MW only allows 75-80% so 3mw transformer will do 2.25Megawatts to 2.40Megawatts. Many people would want a pair of 2megawatt transformers. why well if one fries itself only ½ the farm goes down. if you found two 2.0MVA transformers you could do 1.50 to 1.60 on each one. thus a true 3.0megawatt farm. here is one I have heard issues about availability for these. https://www.larsonelectronics.com/product/283593/2000-kva-pad-mount-transformer-13200v-delta-primary-480y-277-wye-secondary-knan-bell-green? this one does do 480y-277 wye secondary which will work with this miner. https://shop.bitmain.com/product/detail?pid=00020230108213609854b369SGwI0654

Wiring up properly is the tricky/important part as up to the transformer it's high voltage and the power company is the one doing it. I mean without burning the building down sooner than later.

You don't need the J+ for 277V, Bitmain in their usual wisdom does not really market that they in fact have PSUs for x19 family for 277V: APW12A and APW121215g. Newer miners require the later but even the original S19 Pro 110 would work with the first all these years the model has been out... Feel free to ask them why they don't bother listing those. I don't know if there is a variant of the APW121417 for 277V, maybe there is...
