Old Coal Plant Is Now Mining Bitcoin For a Utility Company (arstechnica.com) 59

An anonymous reader quotes a report from Ars Technica: Bitcoin's massive power consumption is the cryptocurrency's dirty secret. To mine bitcoin, computers across the globe chew through enough electricity to power a medium size country, somewhere on the order of the Netherlands or Poland depending on the estimate. In fact, electricity has become such a significant factor that one private equity firm owns a power plant to mine bitcoin. The company, Greenidge Generation, said at one point that they could mine one bitcoin for less than $3,000. Even today -- at $40,000 per bitcoin, some 30 percent off its peak -- the potential for profit is real. Which is why an investor-owned utility has dropped a containerized data center outside a coal-fired power plant 10 miles north of St. Louis. Ameren, the utility, was struggling to keep the 1,099 MW power plant running profitably when wholesale electricity prices dropped. But it wasn't well suited to running only when demand was high, so-called peaker duty. Instead, they're experimenting with running it full-time and using the excess electricity to mine bitcoin.

Ameren executives reportedly blame wind and solar power for the load variability that taxes the 55-year-old power plant. The utility claims that mining bitcoin could reduce its carbon footprint by allowing it to run its plants more consistently rather than ramping them up and down, which they say can increase emissions. "We have pretty dramatic changes in load minute by minute, second by second at times," Warren Wood, the utility's vice president of regulatory and legislative affairs, told E&E News. But when it's running full-time, they only have to take power away from the mining operations. Wood said it takes about 20 seconds to divert power back to the grid.

Ameren attempted to get rate payers to foot a portion of the bill for its experiment, but Missouri's consumer advocate pushed back. "If Ameren Missouri wants to enter into speculative commodities, like virtual currencies, then it should do so as a non-regulated service where ratepayers are unexposed to the economics of them," Geoff Marke, chief economist for the Missouri Office of the Public Counsel, wrote in a filing. "This endeavor is beyond the scope of intended electric utility regulation, and, if allowed, creates a slippery slope where ratepayers could be asked to put up capital for virtually anything." The utility says that if its bitcoin experiment pans out, it could attach similar containerized data centers to wind and solar farms to soak up excess electricity profitably in times of high supply or low demand. The coal-fired power plant that's being used in the experiment is scheduled to be shut down in 2028. Ameren says that so far it's pleased with the project, which has mined 20 coins and mints a new one at a rate of one every 15 days or so. Whether the math continues to work depends largely on the cost of running the plant and the price of bitcoin, which is highly volatile. Based on today's prices, the company has made about $800,000 since it switched on the miners in April.

      If so, with the coin they generate they could purchase carbon credits to offset the emissions.

          That doesn't justify min-maxing the coal burning. We should be shutting down coal plants. Period.

          As mentioned in other parts of the internet. The only way you get away with "wasting electricity" on mining PoW cryptocoins is by operating a green plant (solar/wind/geothermal/tidal) and then instead of ramping up/down the energy, with heating/air conditioning cycles used by the population, is you just redirect the energy not being used to the PoW mining, and reduce wear on mechanical systems involved in stopping and starting things.

          But here's the thing, dirty energy, like coal, oil and gas, are cheap, and converting it into bitcoin is absolutely the stupidest thing we could be doing when we are trying to combat climate change. Carbon taxes have to go up to a point where operating coal, oil and gas can't be used for cryptomining, which means most electricity prices have to go up 10-20x.

          • Yeah, I don't believe in lizard people or anything, but one could hardly imagine a more effective way of getting humans to destroy their planet than bitcoin.

          • It doesn't matter how green your energy source is: using it to mine bitcoin displaces some other use for that power. All other uses are higher priority than bitcoin.

            • The confusing thing to me is how anyone can justify mining bitcoin. You could use excess energy for actual carbon capture. Turn the carbon into synthetic fuel, plastics, mineral, anything.

          • All energy production ends up being "dirty" if you look at it without bias, the differences are what type of waste byproduct is generated, at what scale, at what point in the process, and by extension how easy it is to deal with.

            In theory a coal or gas fired plant could be built which fully captured emissions, making it "clean," but it would be significantly more expensive.

            • That's kind of impossible. You can clean the non-CO2 biproducts with some reactions that usually turn compounds like CO into CO2 or bind to the small quantities of toxic metals that are also burned. But the long term hazard is the CO2 and you can't store that without adding a lot of energy. CO2 is already in it's most stable state, you either need energy to convert it into another molecule or energy to compress it. Plants use the chemical method with the added energy coming from the Sun and there's no funda

          With coal you simply stop putting as much coal in. If you look at the specifications you will find coal and nuclear are remarkably similar - e.g. for the latest plants a ramp rate of 5-6% per minute and a minimum operational power of 50% (Nuclear) or 40% (Coal). The big difference being that Nuclear plants are often limited to one or two changes per day. That's pretty typical for any thermal (steam driven turbine) plant. Overall coal is probably more flexible than nuclear simply because the consequences

        • Nuclear cannot be ramped up and down the way you think. For the same reason that you can't change coal output so quickly. Once you have coal loaded in the burner its going to keep burning and producing heat. You can stop adding new coal but what is there keeps burning. With nuclear, even after you insert the control rods fully, the fuel in a nuclear reactor is still very hot and you have to convert that heat to steam (which you can then either use to turn a turbine or just vent and waste). But the fuel
          • Nuclear cannot be ramped up and down the way you think.

            Depends on the design of the nuke plant. Yes, it's possible to design one with highly variable output and quick load-following. Nuclear subs and surface ships use them.

            Hell, a civilian plant can do load-following - just vent steam when as needed - wasteful of U-235, but it's not like there's a shortage of the stuff, since we make it.

            • Yeah I think that both the OP and I mentioned that one *can* vent steam. I have no idea what the downsides are to doing that and I don't know anything about military nuclear power. I can only state that civilian nuclear and coal power plants are deployed as base load.

      It's actually just a return to form. Prior to WWII, human civilisations had spent centuries expended huge amounts of economic effort on digging gold out of the ground. People died, their entire lives were shaped by it, empires built and destroyed, the environment destroyed. Almost all that gold just sits in vaults now doing nothing useful. If all that effort had been expended on building real assets - infrastructure, factories, housing etc - everyone would have been better off, but this was not apparent (or at least, was not politically feasible) until the post war period. That lasted until around the 1980s, and we are basically back to employing vast quantities of human effort towards operating a rube goldberg machine for fighting over the assets that are actually still being produced.

      In the same way we can't really understand how so many people could have wasted their lives digging holes in the ground in the middle of nowhere, one day we will also see how stupid our present financial system is. Unfortunately probably not for a very long time though.

        ... Civil forfeiture allows police to seize — and then keep or sell — any property they allege is involved in a crime. Owners need not ever be arrested or convicted of a crime for their cash, cars, or even real estate to be taken away permanently by the government.

        Forfeiture was originally presented as a way to cripple large-scale criminal enterprises by diverting their resources. But today, aided by deeply flawed federal and state laws, many police departments use forfeiture to benefit their bottom lines, making seizures motivated by profit rather than crime-fighting. For people whose property has been seized through civil asset forfeiture, legally regaining such property is notoriously difficult and expensive, with costs sometimes exceeding the value of the property. With the total value of property seized increasing every year, calls for reform are growing louder, and CLRP is at the forefront of organizations seeking to rein in the practice.

  • This is what is wrong with our political leaders. A trivial bill would say either no, you can not re-open a coal plant, OR that it must generate less than 1/2 of the CO2 / kWh OR be below a certain limit, if a plant is re-opened. Regardless, we need to stop the re-opening of coal plants. America WAS headed in the right direction, but not if we allow coal plants to re-open.
