You have the choice of selling your excess power to the grid so your co-gen is not a factor in your mining decision. You're already in a profit position by selling to the grid. You would lose that if you start mining so you'd be effectively using grid power and paying grid price to mine.
The're no environmentally friendly angle to this. The best thing to do is sell as much as you can to the grid. Mining has an environmental cost, there's no way around it.

I'd guess that an operation that size would only get wholesale rates for the power they sell back to the grid, so they may not even make enough to cover their cost. menoiazei, do you know what rate you can get when selling back to the grid? Also, if they haven't already built the facility, attaching to the grid in a manner to supply 800KW is likely a significant cost and headache. At current diff and price (20T and $13100), 55w/th (stock firmware t17) will make 6.4c/kwh, 45w/th (s17) makes 8.4c/kwh/th, and 37.5w/th (s17 pro) makes 9.4c/kwh.

Have some dead Bitmain 17 series hashboards or full miners? I'll buy them ... send me a PM with what you have and I'll make you an offer!

Thats true, i buy at 5 and sell at 135 for power, regarding the eco aspect of we are growing some trees in the meanwhile and filtering some CO2 from them so thats something! Selling to grid or putting power to coins is what i try to decide and will go for the option that gives me the best return on investment because all this operation as you understand cost a lot.

I am based in Europe, at this operation i buy at 5euro and sell at 135 because of the cogeneration for the MWh

At a price of 2 cents, you can buy any equipment that mines cryptocurrency. Even asik S9 will pay off in 2-3 months. It is possible that old ASICs will cause more problems due to breakdowns, but I think that their cheap price and the ability to collect 1 worker from several broken ASICs will compensate for all the inconveniences.
Looking for cost efficient options for equipment so would like to hear any input on sourcing equipment for the job, also might be open to potential synergies for this project, if it makes sense of course! many thanks! Thank you, in Russia so inexpensive electricity is 3-4 cents and I only use video cards. And there are regions where the cost of a kilowatt is about 1.5 cents (Irkutsk region). I have a question, are additional voltage regulators required for your Co-generator? Hello, Not sure that i understand the question regarding extra voltage regulators, generator as a unit uses voltage regulators, by co-generation what we do is use the generator operation to heat and cool the greenhouse also the exhaust to provide CO2 to the plants in the greenhouse, by doing this you save a lot from the greenhouse operation and is an eco friendly way to this in a way. I confused it with a gas generator. On the manufacturers' websites it is written that after the gas generators it is necessary to install voltage stabilizers if it is planned to use electronics. And for lighting purposes and where stable 220 volts are not required, the stabilizer can be omitted.

Thats true, i buy at 5 and sell at 135 for power,
I presume that's 5.00 vs 1.35? You just need your generation cost to determine your marginal power cost (the cost of the last watt) if you begin mining. If you already had mining equipment it would be a no brainer but trying to ROI with all new equipment plus power is challenge in the current environment. Keep in mind there is a downward bias to mining do to block halving and increased hashrates pushing difficulty higher. Prices must increase to counteract.

No is 135, reason being the Cogeneration raises the price grid buys from you by 30% of the normal price with a 20 year contract then 5 is discounted electricity that we buy from the grid to operate everything Cogeneration here is pretty good ROI selling to grid about 20% of investment annually as far as coins, have the building infrastructure and power to house a pretty decent mining operation, question to me is what coins and equipment and what would be the ROI and best way to orchestrate this operation...

That's a pretty sweet deal. Mining is tough. I don't think you can beat what your getting selling to the grid.

ROI from the grid and greenhouse production is all good looking at it as another potential flow of income for my operation and a potentially interesting business venture if i decide to do so, also love the bitcoin/crypto idea too from the economic and idealistic viewpoint of it!! just curious JD if you had dirt cheap electric power and some capital to invest for it what would you go for??

And a greenhouse? I'd grow cannabis, it's legal where I live. I would not invest capital in a mining operation at this time.

with 800kw you can build 320 rigs : asus b250 18 pcie + 2k psu + 8 gb + 120 gb ssd + 16 rx5700 eth hashrate 900mhs/2500watt 800kw/2.5kw =320 rigs x 900mhs = 288ghs in curent day you will be made 7750$/day nice profit but not easy to get the hardware and need times to build

What would be the cost of something like that?? any information about sourcing parts and setting it up would be most welcomed!! Many thanks for the input

Right now looking at the option of buying some L3+ units from Sz i wonder if anyone had ever set-up something similar in the past and can give some insights on what to do and what Not to do... Again many thanks for any usefull information!!!

What units are you using for the power price? Is that 1.35 Euro/kWh vs 0.05 Euro/kWh?!

First I am smaller then you. but I burn 100 to 150 kwatts 24/7/365 l3+ are very reliable gear. buy some say 50 to 100 use good psu use good switches 48 ports are good choice. set them on static. pretend your internet router is . 192.168.1.1 to 192.168.1.256 you have 250 spots number 💯 with a sharpie pen say 100 then 101 then 102 all the way to 199 set them in rows with number order. mine at a site like viabtc.com it will show every miner right in a row. as you match worker name to static setting ie greenhouse100 is static address 192.168.1.100 greenhouse101 is static address 192.168.1.101 greenhouse102 is static address 192.168.1.102 this way you can find dead ones easy peasy. dont go crazy with a shit ton of gear. 50 to 100 l3+ are more then enough for a start.

Thank you very much for the information Phil!!! As soon as i receive the hardware and start setting everything up will start posting pictures too and sure will have many more questions...

Also what about solo vs pool mining for an operation of say 50-100 units l3+? would solo mining make sense there or pool would be the way to go??

let me check math. 100 l3+ = about 50gh about 1.32 coins a day on vabtc.com guaranteed daily payout if you go solo and do it correctly you could hit a block every 9-10 days with standard luck bad luck you can go as much as 90-100 days. I personally would say do viabtc for a month collect the guaranteed coins . The consider a solo shot. 30 days on viabtc.com should earn close to 40 ltc If you want to try solo for 10 days and hope for 2 blocks vs 0 or 1 you will have coins in the bank.
