800kW of power and a greenhouse

[menoiazei]

 Got Co-generator* greenhouse operation powered by a 800kW caterpillar generator
Producing 6400MWH a year of electricity, heating and CO2 for a 8000square meter greenhouse.

 Exploring options and potentials for coin mining and hardware.

initial idea is to go for litecoin

Would like to hear opinions here.

Many thanks!


*Cogeneration—also known as combined heat and power, distributed generation, or recycled energy—is the simultaneous production of two or more forms of energy from a single fuel source. Cogeneration power plants often operate at 50 to 70 percent higher efficiency rates than single-generation facilities.

so 6,400,000 kwatts in a year is  17534 kwatts a day or 730 kwatts an hour which makes sense with a 800kwatt generator.


Simplest question what is daily power cost for it?
How many spare kwatts of the 730 an hour can you spare?

if you found old ant miner l3+. and budget 1 kwatt an hour for them running 200 units seems easy.  200 x .5 = 100gh of hash which pays $120 a day

You could run 220 x S19 Pro's for $1900 a day on 730 kwatt!

The co-generation of heat, in this instance, would be a negative though for obvious reasons...

 i will look into the S19 i was looking for l3 + or l3++

because of co generation contract price for the MWh is cheap(basically the LNG cost for it) since set-up investment buildings and everything already there trying to figure out if is a profitable idea that makes sense,

Co-generation generates heating and cooling 

thanks for replying

Calculation is correct,
i can use all the power to generate coins Vs sell it to the grid, or do both for x amount of power
cost of electricity to me basically is the LNG cost to feed the generator

trying to dig more into this and figure out if is a good idea that makes sense!

thanks for replying

If your only paying lng cost then your probably in the 2c per kwh range with a reasonably efficient generator of that size. This gives you options to be profitable with miners that you can get for pretty cheap. With power that cheap I would not advise paying the premium for the latest miners. Maybe look for T17s for less than $10/th. Or Canaan 1047s, or any other in the 50 to 60 w/th range.

Also would not advise anything other than btc, it's much more risky to put that much investment into altcoin mining.

Thank you for the reply,
Why do you think btc only?? dont you think ltc or other established altcoin maybe more profitable in the long run?

Thank you for the reply,

Maybe start slowly with some ASIC miners for BTC. Later when you gained some experience you can mine ETH or LTC, too.
Go for the biggest coins because they have the most pools, wallets, exchanges...

In which country is your greenhouse located?

[safar1980]

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.

BTC will be more stable, both in price and in mining hardware. Profitability can change very quickly on altcoins.

If he is at 2 cents he should get t17's and l3+ a mix of both

maybe 25 t17's and 100 l3+

that is about  25 x 2.2 = 55-60kwatts

and 100 x .8 =  80 kwatts  he can work from there.

he can get t17's pretty cheap maybe 400 each.

  Was thinking solo mining not pools since we have the power available, greenhouse located in remote area of Greece!

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!

Any advice on the potential set-up and hardware would be most welcomed!

That sound like a good plan!!

very profitable now etc

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.

About Co-generator Greenhouses in general*

Greenhouses can use combined heat and power (CHP) or cogeneration in order to provide heat, carbon dioxide and electricity. Surplus electricity can often be sold into the local electricity grid. Gas engines are highly efficient at providing the stimulus for the growth of plants, whilst in parallel providing a flexible supply of electrical power. Heat, light and carbon dioxide (CO2) all promote plant growth. Gas engines provide electrical power at the alternator and when in a cogeneration configuration can also recover useful heat. Carbon dioxide is released in the exhaust gases of the engine as a by-product of the combustion of the fuel gas. Electrical power can be used to provide energy for lighting or can be exported to the grid, heat can be stored as hot water for use when needed and finally the CO2 can be scrubbed and used to promote plant growth.

Benefits of CHP for Glasshouses
Efficiency levels up to 95%, therefore high contribution to resource conservation and maximisation of profits
Provides power to grid at times of maximum demand hence receiving highest power sale prices
Time-independent supply of CO2 and heat through heat storage
High quality CO2
Carbon Dioxide from CHP Engines and Plant Growth
Plants grow by converting CO2 to carbon through photosynthesis. Air generally contains approximately 350 ppm CO2. Optimal CO2 levels depend on the type of plant and generally lie above 700 ppm. With increased artificial lighting, as present in greenhouses, plants absorb even more CO2. If the greenhouse atmosphere is enriched with CO2, the temperature kept on a constant level and enough lighting, provided plant growth and consequently the harvest yield can be increased significantly. When burning natural gas in gas engines, approximately 0.2kg CO2 is produced be kWh of energy input. This CO2 is present in the exhaust of gas engines in a concentration approximately 5-6% by volume.


The energy created by gas engine combined heat and power systems in glasshouses can be used in various ways. The electricity can provide the power for the artificial lighting and/or be fed into the electricity grid
or maybe to generate coins**
. The heat efficiently meets the glasshouse’s requirements. In addition, the climate relevant CO2 of the engine exhaust gas serves as a fertiliser for the plants.
