4 sats \ 3 replies \ @BTCMiner 26 May 2022 \ on: Tesla delivers Megapacks to new Bitcoin mining facility bitcoin
The idea is to build a new 30 Petahashes per second open-source Bitcoin mining facility powered by a 3.8 MW solar farm and 12 MWh Megapack system provided by Tesla.
Blockstream raised ~$40 million for the project through a token, which enables people to technically invest in the Bitcoin mining operation powered by Tesla Megapacks and solar by trading the token on Bitfinex.

This doesn’t make sense. $40mm / 30 PH is $1,333 per TH. At most the machines cost $100 per TH, likely closer to $80 per TH. So if the energy infrastructure cost $1,250 per TH then at current machine efficiency it takes about 78 years of free operations to get to $0.06/kWh.
I think the $40mm refers to all of what Blockstream has raised using BMN. I don’t think all of it has been invested into this project.

Is the only purpose to mine Bitcoin? Or will the solar farm also be able to sell power to the grid?

Your rigs are profitable up to $0.15 per kWh, and the grid is willing to pay $0.25 per kWh.
Would it be a rational economic decision to turn off the rigs and redirect that power to supply the grid?
Yes, yes it would!!
However, this installation is a "pilot" and is also "off-grid", so there's no ability to supply the grid, as far as I could tell. But if this proves that bitcoin mining using solar + battery works well enough to be viable, future expansion could be built where supplying the grid when it is profitable becomes a capability as well.
