There are no good websites. The only way to find out is to find the public utility tariff, put those numbers into a spreadsheet, then call the utility to confirm.

U.S. wholesale energy price is going up by a cent because natural gas is very expensive now. But it depends on the region. PJM & ERCOT are seeing big increases while I would guess Washington/New York aren't as affected because they use hydropower.

$31k coin, 1 cent more for power... we're approaching the production cost of many U.S. farms which currently pay 6-7 cents for their power and 1 cent for rent. They won't make profit anymore.

If the revenue from the equipment can't cover the power bill, I would shut off the equipment. I don't have free electricity, but it is quite cheap for GPU mining at 6-7 cents. I learned my lesson in the past: I should've kept mining at a larger scale during 2019-2020. The real problem is the rent for a small warehouse, which is $2000+/month. That comes out to 2-3¢/kWh. So my cost base would be the same as a home miner. At least I built special software for stratum switching which can boost revenue by 10%+.

I plan to do the same thing since I have witnessed the 2018-2019 bear market in mining. Even if there's never a big GPU coin again, the ROI seems to be 20-40% at 7¢/kWh for a farm with 500-1000 cards, which is still good.

I see crashes as a great opportunity to buy equipment at below-MSRP prices. I will make money no matter what direction the market goes in.

That isn't possible because it takes a few days or a few weeks from when miners buy new rigs to when they are online. Probably just a random fluctuation or coin profit-switching.

A more extreme example of difficulty lagging behind profitability is ASIC mining, where mining farms take weeks or months to build, so hashrate takes a long time to catch up.

I have the MSI Ventus 3x RTX 3060 12GB model. The highest stable memory clock is +2200 MHz on Linux (+1100 Windows). I use MinerstatOS with T-Rex. The memory clock is why I'm limited to 46 Mh. One or two of them can probably get the same hashrate as you, but I need to make sure the entire rig is stable.

What is happening is the memory is now being utilized to the max, so the temperature will be higher. This is also why the overall power usage of the card is 14w higher.

I have a rig of ten RTX 3060's. 50 Mh is unrealistic except for the top 1% of golden samples. Most of my cards are only stable at a +1000 Mhz memory clock, which comes out to 46-47 Mh.

I foresee $0.80-$0.90/day of revenue for an RTX 3080 card in the real bear market. This is how conditions were during 2019. What will probably happen is ETH will be unprofitable and most GPU rigs will be mining FLUX/RVN/FIRO/etc. That's what happened in 2019; GRIN provided double the revenue of ETH.

Even at 7¢/kWh, the power cost will be $0.45/day. That leaves us with $0.40 of profit on average. Even if you bought the RTX 3080 for just $400, it would take > 3 years to pay it off. The only hope would be another GPU gold rush.

It is much more expensive than $10k to mine a Bitcoin. Let's assume a farm buys an Antminer S19 95T for $6000 (includes buildout cost) on 5¢/kWh power. The power cost per day is around $4.00. Let's depreciate this miner over 4 years, which is $4.11/day of capital cost.

Cost to run the S19 = power + capital cost = $8.11/day
Bitcoins earned = 0.000407
Cost to mine a Bitcoin = 8.11 / 0.000407 = $19,926

So it's ~$20k to mine a Bitcoin for the average farm out there. I plugged less efficient and more efficient ASICs into this equation, but the end result is the same.

I really recommend mining FLUX on your GTX 1080 Ti as well as other Pascal GPUs or the RTX 2000/super series. WhatToMine shows the profit is ~10% higher than ETH. The only downside is power usage will be about 200w.

The increase will be very small (3-4%) because LHR video cards are a fraction of the network hashrate, even under worst-case assumptions.

These kinds of comparison websites can be really inaccurate. The worst one is ElectricityLocal.com. Commercial tariffs are structured completely different from residential tariffs. Most of the electric bill for miners will be the energy, not the delivery unlike for houses. Yes, states with cheaper residential rates tend to have cheap commercial rates, but people really need to look at the 100-page tariffs.

Well, now that BTC price has plumetted even further, I think the M30S/M31S or T19 is a better buy at a 6¢ power cost.

It was far more profitable to mine GRIN/RVN since I had GeForce cards. Revenue was $0.60-0.80 while power was $0.25/day. At least the video cards only cost $135 for GTX 1060 6GB's.

That's an excellent rate. It might be a good time to buy more ASICs since BTC price has fallen more. I definitely know a few people who have enough capital to buy a few hundred kilowatts of miners, but are having trouble finding a decent mining site + somebody to maintain it. Send me a PM if you want me to get you in touch with them. Perhaps the three of us can each bring something to the table. I myself have custom software to boost profit and I can do most of the boots-on-the-ground work.

Nope, I tried everything, it is locked to 1328 MHz max. Flashing the BIOS is extremely difficult on all NV cards newer than Maxwell. Power limit is not the problem. Welp, at least they are very efficient cards considering their age...

The price of commercial power at 1 MW of load (300 S19/M30S ASICs) on publicly available tariffs in competitive markets is 5¢-10¢ in 95% of the cities in the U.S. The remaining 5% of the country has power cheaper or more expensive than that. States like Washington, New York or Texas have rates on the lower end of that range, while CA/NJ/FL are on the upper end.

Mega miners usually sign special deals where they can buy bulk power directly from generation stations for as little as 3-4 cents. The cheapest source is probably flared natural gas.

Sadly, most of us are stuck with using grid power. I can speak to North Texas in particular: the rate at 1MW primary on ONCOR was ~5.7¢ over the past 12 months with 96% uptime (other utilities are similar). In eastern Pennsylvania it is 7-8.5¢.

The delivery charge is usually 1-2¢ of the bill for most utilities, and usually goes down as you use more power and/or buy your own transformers. The energy charge is typically 3-6¢ on the open market.

Rates can vary tremendously in different parts of each state. Upstate New York has cheap power (4-6¢), but Long Island is a ridiculous 12-15¢. You also need to watch out for smaller utility companies in non-competitive areas. I visited a warehouse in the Middle of Nowhere, Texas where I thought the rate was 6-7¢, but it was actually 8-9¢. In general, if you're using grid power, don't set up shop in a rural area because they won't have enough power available.

Is the energy price in the U.S. reasonable for ASIC mining? Of course, as long as your farm is in one of the cheap-energy states and you don't use equipment that is too old. Looks like the sweet spot is 40W/TH, while miners less efficient than 60W/TH are risky especially with the falling BTC price. The higher the power price, the newer the miners should be.

The biggest factor you'll need to worry about with a U.S-based farm is the tax law. The coins are considered income the moment they arrive in your wallet. Therefore, you need to re-invest the coins into new equipment before the end of the year to avoid income tax.

Let me know if you need any help estimating your energy cost. I have spoken to a few energy brokers and I have custom software to calculate historical market rates, then find the best hardware based on that rate. It can also lower power usage during peak pricing.

The only workaround to the Pascal TLB bug is to run at a higher clockspeed, but that means more power usage, as you discovered. Unfortunately I can't do this on my P100 16GB cards since all the clockspeeds are locked because it's a 'datacenter product' according to NGreedia.

If you think $1.50 of revenue/day for 100 Mh/s is too little, wait until the true bear market starts after ETH PoS... we'll be lucky to get $0.80/day of revenue for 100 Mh.

Totally agree. It will be a matter of time until the prices of LHR cards rise, while FHR cards decline. But I would wait for another 1-2 weeks so the recent downturn in BTC/ETH price is reflected in video card prices.

That is what I will be doing as well. Now that BTC is cheap, I'll dollar cost average all mining revenue into buying BTC. At the end of the year, I'll decide whether or not to build more rigs. If PoS gets delayed or the PoS merge already happened, I will build a lot more rigs.
