so 30eh = too high

thus there is no way that 1000MW is producing 30 Exahash

You neither! Grin

I was looking for the best numbers, a guy has the right to dream a bit, I'm entitled and demand for everyone else to do the same!!!!

One thing, now seriously, the whole cooling thing, I don't cool itself is such a large part of energy consumption, the fans we have for ventilation of the whole building are rated 600W and 3100 m3/h. Semnificative yeah, but large no, also they mentioned "more than 1000MW".

Now for some numbers: 118 blocks in the last 24h, means 81.9 pace, so allow me to still dream about it.
The last block was 37 minutes ago, next block fee 32 sat/b, something is definitely happening.

30eh is too high for texas. but 35eh appears to be happening . Look we have 1.7ph on high but we are set to low about 1.4 ph

a lot of guys have 10kwatt setups with paid off gear some set too low.

so
42th
52th
57th

for an s17 means a lot of 3 or 4 or 5 s17 guys have cut power.

I am eager to see if we keep popping 111 block days from now til July 22

There are also a lot of miners shutting down older less efficient gear in the northern hemisphere now that these hot summer days are fully here. Just in general for the difficulty drop how many S9 and equivalent generation miners are being shut down with electric costs going up and dealing with the heat and....
All of my gear is off, I could probably make a profit on the surface. But every hour I run my air conditioner is one less hour it will work later. Since I would be selling to cover costs and so on it's just not worth it.

I have said it before and I'll say it again. Individually 1 and 2 miner people are not that big a deal. But I really think there are a lot more of them out there then people think.
And from what I see in the data center that we rent space in I can see how many businesses have a few miners running. How many others are there in the back of offices or warehouses or....

Getting a bit OT from the original point but I do think hot weather does matter more then just in TX for the overall hash rate. Is it more then 2% or 3% tough to say. But it is there.

All depends on the 1000 mw number.

some have mentioned 30eh
some have mentioned 20eh
some have said do not forget the cooling

so 30eh = too high

and 20eh = maybe

and 15eh = truly the correct number.

diff has dropped over 4.5%

since we were at the 600 block number

various quotes below

Mikeywith. "...Current Pace: 102.9694% (593 / 575.90 expected, 17.1 ahead)..."

a1 hahrate llc2022 '...Current Pace: 99.3455% (883 / 888.82 expected, 5.82 behind)...'

https://www.bitrawr.com/difficulty-estimator ..."Current Pace:   95.5248% (1085 / 1135.83 expected, 50.83 behind)"

please note all was original from bitrawr.com

so from 593 to 883 we dropped about 23 blocks so 290 should have been 313 a solid drop of 7.34 %

and we do not know at what point gear was shutting down

and from 883 to 1085 we dropped 45 blocks a huge amount say 202 should be 247 so 45/247 = 18.21%

now if that is a true number Texas is kicking ass.

we need to keep clocking the diff

  593 +17
  883 - 6
1085 -51

and 18.21 % is over 30eh i think. So we are likely seeing a big Texas shut down combined with many others that are tapping out due to heat and Low profits.

Bitcoin miners in Texas (Riot Blockchain, Argo Blockchain and Core Scientific) have suspended operations and answered the call to conserve energy and spare the Lone Star State’s fragile power grid as demand has soared during an intense heat wave.
“There are over 1,000 megawatts worth of Bitcoin mining load that responded to ERCOTs conservation request by turning off their machines to conserve energy for the grid.” Lee Bratcher, president of Texas Blockchain Council told Bloomberg.

Some Some Fun Facts based on that; Using the often quoted 3.6 cents per kWh, taking 1GW offline translates to:
$36/hour per MWh or $36,000/hour per GWh
x24hrs @ 1GWh = $864,000 per day
That would be direct 'lost' revenue to the electric provider from mining but of course the power IS being used elsewhere so for ERCOT it's more just a matter of shuffling numbers between inputs in a spreadsheet.

In and of itself $864k per day would also be what the mining companies are spending for power which in-turn tells us that said companies are (were) mining enough coins to pay that AND pay for the infra/miners and still make decent profits....

As pure Speculation I'd think that ERCOT pays the miners perhaps 1/4 to at most maybe 1/2 of their averaged bill for the shutdowns. If so at least that should be good for at least paying off the infra and miner gear debts so the mega-mining companies are certainly not hurting much. Wink

Also keep in mind a good potion of that power is not for mining but for cooling.
And as others have pointed out we don't know if it's all the latest and greatest gear or even from whom.

The other point that I think many of us know too well is some gear has been known to not always power back on after being powered off. Not that I am pointing fingers at any particular manufacturer here.....

1 000 MW?
At 3.3kw per machine that would be 300k asics? 30 exa? 15% of the hashrate?
Where am I making the mistake? And If I don't, $$ eyes!Wow, the diff is down to 95% pace, is this actually real??? Inserting $$ eyes again!

Now, the other part, does this mean Texas has 15% of the hashrate?

Nothing wrong with the math, but we can't go with the assumption that 100% of the 1000mw is S19s and the equivalent, and thus there is no way that 1000MW is producing 30 Exahash, also some or many of them could be overclocked, and thus losing efficiency, also since the 17 series and the same generation of what's miner are almost half as efficient, allow me to throw 20 exahash at the wall.

But hey, let's pray for a pretty damn warm summer in Texas, I mean nothing is wrong about ~~making more money~~ getting more Vitamin D. Cheesy
