Before anyone jumps the gun and says this is a political move, this is quite likely just economics.

Peak coal was in 2007, and has been falling rapidly since. We are currently generating about 1/3 the electricity from coal in 2023 vs 2007[0].

    Granite Shore Power, the company that owns the coal plant in Bow, New Hampshire, said they ceased commercial operations September 12th, about a year and a half since they announced they would retire their facility by 2028 as part of a settlement agreement with environmental groups.

    Yes, natural gas is now cheaper than coal for power generation, and solar has become much cheaper. Even disregarding environmental concerns, it's just not a good choice any more.

      NE is starved for natural gas. They replaced the coal plants with gas and didn't bother to build enough pipelines (and even blocked them). We are getting a lot of our gas from Tankers from Europe and even Russia before the war. So now NE has nearly the highest electricity costs in the country even though we're not far away from some of the most abundant natural gas in the planet.

      I'm curious, in case anyone knows, how much of the economic disadvantage of coal is because of environmental reg compliance versus other, more fundamental costs?

        You can't put coal in a pipeline.

        You have to physically handle every piece of coal. Extract, load ship, unload.

        Natural gas is shooting out of the ground in North Dakota.

        You can compare to wind and solar also.

          https://en.wikipedia.org/wiki/Coal_pipeline

          A slurry is transported in one variety of these. The trick is to induce a swirl in the flow, so even though particles are constantly falling out of suspension, they stay suspended. It's mathematically analogous to how putting a twist in magnetic field lines in a tokamak (or stellarator) prevents ExB effects from driving the plasma into the wall, as they would in just a plain toroidal magnetic field.

          Lots of water is needed and drying the coal before burning it adds cost.

      • xbmcuser 14 hours ago

        Coal requires manual labour and mining so even without environmental regulations it's expensive. In the US coal use decrease had very little to do with environmental factors most of it was because fracking brought in cheap natural gas and pushed coal out.

        • jhallenworld 13 hours ago

          Its does, but you should see the machines they use for coal mining these days, particularly in Wyoming. A giant strip mine seems to require like 20 workers, but with giant trucks and excavators.

          Even for underground mines, check out the massive longwall mining machines they use- it's kind of astonishing. They pretty much take all the coal.

          I think this is lost in the political talk about protecting mining jobs- the main original competition is more efficient mining operations.

          Anyway, it really says something that natural gas and solar are cheaper than coal given this context.

          • fragmede 13 hours ago

            You should see this one! https://youtu.be/azEvfD4C6ow

            It's a bit dated (completed in 1978) and cost approximately $100 million. At one point it was the heaviest land vehicle, clocking in at 13,500 tons. It's since been succeded, but this bucket-wheel excavator needed only five people to operate. Those five people could mine 240,000 tons of coal[8] or 240,000 cubic metres of overburden (rock/soil on top of the coal) per day. That's 2400 coal wagons!

            After totally tapping out all of the coal at the Tagebau Hambach mine, in 2001, it took a crew of 70 together to move it 14 miles to the next mine. This move cost 15 million German Marks.

            (Just watch the linked documentary.)

      • LarsAlereon 15 hours ago

        I think it's primarily a fundamental cost issue. It's simply far cheaper to get an equivalent amount of energy from fracking a natural gas formation than having to literally dig coal out of the ground.

      • chris_va 14 hours ago

        (disclaimer that I manage a climate&energy research group)

        Most of the comments here are speculative.

        The TLDR is that coal plants have trouble ramping their production up/down quickly, unlike natural gas which can do so in minutes. So, if you have a grid that is being thrashed by variable production (renewables), this results in variable pricing and demand for baseload. Coal cannot economically compete in that market (and neither can nuclear, which has the same problem).

        • mrDmrTmrJ 13 hours ago

          Given that renewable power power is self correlated (all the solar panels are producing at once - or they’re not, all the wind turbines are turning at once - or they’re not) - renewable energy leads to low prices when it’s produced and high prices when it’s not.

          Why not put massive, grid scale batteries “behind the meter” at a nuclear or coal plant to enable continual production but only sell power when prices are high and store power when prices are low?

          • not2b 2 hours ago

            No, because as the parent comment suggests, if you have solar+wind backed by natural gas and battery storage, if the battery storage isn't enough the natural gas plants can quickly fire up. But coal plants don't have this ability, so it doesn't work as well in this environment (which is today's environment).

            Even better, if you have a functioning wholesale electricity market, you can put those batteries on the grid and benefit everybody.

            Once you have batteries you may do so with solar or wind

          • pfdietz 8 hours ago

            Batteries are also highly useful for relaxing transmission constraints. I've seen a claim that sufficient storage (at various places in the network) could increase the energy transmittable over the existing grid by a factor of 3.

            An analogy here is natural gas pipelines with intermediate storage caverns, which allow the pipelines to operate more steadily even if demand various greatly over the year.

      • eru 15 hours ago

        Well, if you want to answer that question, you probably also need to figure out the hypothetical cost of the other power sources minus environmental regulations.

        Nuclear would be (and used to be) massively cheaper, before regulations went wild against it.

        I'm deliberately saying 'went wild', because the earlier nuclear power generation that was built to saner standards also has turned out to be incredibly safe already.

        (Basically, anyone who avoided insane Soviet bullshit had safe nuclear power, as measured in eg fatalities per Joule of electricity generated.)

        • bryanlarsen 15 hours ago

          The regulatory costs of nuclear are mostly occurred in the design phase. Those costs are sunk and mostly irrelevant for new builds of old designs.

          The fact that old designs like the AP1000 are crazy expensive to build has a lot more to do with the fact that the US sucks at building mega projects than anything else.

          • dalyons 13 hours ago

            It’s not just the US that sucks at mega projects. It’s everywhere that’s not china.

            • bryanlarsen 4 hours ago

              Other countries are better at building particular types of mega projects. Some are better at transit, others are better at building tunnels, others are better at building massive ships, et cetera. But in regards to nuclear, I believe you're right.

          • fragmede 13 hours ago

            Interestingly, one of the reasons the design phase for nuclear is so onerous is the sheer amount of red tape involved due to compliance and other regulatory reasons. You wanna know something funny? You know what's really good at generating piles of convincing sounding bullshit that it's possible no one even actually reads, and looks like it's totally going to insert fuel rods into the nuclear power industry?

            LLMs!

          • pfdietz 8 hours ago

            I'm getting the impression the problem isn't any particular regulation, but rather than because regulations exist, the design is fixed.

            Getting a design approved means a specific design is approved. So, the power plant must be built as designed, no changes. And apparently ensuring you built exactly what the design specifies is really expensive.

            What's needed to reduce this cost is having some way to get a whole cloud of closely related designs approved, so that reasonable deviations from the design are also approved. This is equivalent to saying only the most critical part of the design would need to be built as designed, everything else would be allowed some slop. With something like this, one might (for example) be able to build the confinement building with less tight control on the configuration of the reinforcing steel.

            I'm don't know how one would get such a cloud of designs approved. Maybe this is a problem that could be solved by massive computation? Run billions of mutant designs through a simulation gauntlet to see how sensitive it is to various perturbations? Or maybe add more defense in depth, like devices that scrub radioactive elements from steam (such things exist) so the tolerable chance of meltdown can be allowed to increase while keeping expected damage in check?

        • ViewTrick1002 11 hours ago

          The American nuclear industry was collapsing due to spiraling costs before TMI happened.

          This ”before regulations” time period seems to be made up on feelings about a rosy picture of the past rather than actual data.

          • pfdietz 8 hours ago

            It wasn't just spiraling costs, but also the collapse in the steady 7%/year growth in electrical energy demand. Without transparency on demand growth, very long term investments become risky (a risk reflected in the bankruptcy of WPPSS). The passage of PURPA in 1978 also didn't help with this as it allowed a flood of non-utility generation onto the grid, helping soak up what demand growth there was.

            It looks like the top-end estimate is that the Fukushima disaster may have caused up to 500 additional total lifetime deaths from cancer. Roughly 23,000 people per year died of diseases attributed to coal power plants in the United States alone from 1999-2020.

            Edit: Changed "linked to" to "attributed to", because this is the estimated count of people who would not have died of disease if coal power plants were not running.

              People whose metabolic reserve is low often die when you stress them.

              I saw a study claiming 440 excess deaths from the Los Angeles fires. I'll make an assumption that permanently moving old and health impaired people from the Fukushima exclusion zone had a similar increase in mortality. And then a bit of looking leads me to this.

              "The evacuation itself also was not without severe consequences. The accident was in the winter, and the evacuation of 840 patients or elderly people in nursing homes and health-care facilities apparently resulted in 60 immediate deaths due to hypothermia, dehydration, trauma and deterioration of serious medical conditions (Tanigawa et al 2012) and upwards of 100 deaths in subsequent month"

            • eru 12 hours ago

              Fatalities per Joule of generated electricity is extremely low for nuclear power, even if you add not just Fukushima but also Chernobyl.

              So if you'd scale up, and keep that level of safety, it would be fine. Even less safety would be fine. After all, we accept much less safety in eg natural gas or even solar power. (Solar power is extremely safe once running, but if you look at casualties over the lifecycle, you get a few people falling off roofs when installing residential solar power. It's a very small number, but nuclear is so safe, that the roof-fall incidents of solar are a big number by comparison.)

      Including regulatory and litigation expenses, this is simply not true. That said, coal is very dirty and is not the best choice for power generation because of pollution. Coal is pretty cheap, and it's take most of my lifetime to change the cost through regulation, litigation and lawmaking.

      • toomuchtodo 15 hours ago

        Unlikely. The ISO has 3.5GW of solar and nuclear capacity equally (I’m aware of capacity factor of solar vs nuclear, but the ISO also reports ~6GW of behind the meter distributed solar which only manifests as reduced demand). The ISO needs more batteries, renewables, and transmission from hydro in Quebec, Canada (1.2GW), but nuclear is not needed to succeed long term and those two generators will eventually be decommissioned, as their license only extends their operating period to ~2050. Twenty five years is plenty of time to replace their 3.5GW of output; 18GW of battery storage, 17GW of wind, and 13.5GW of solar is in the ISO’s interconnect queue or has been proposed by developers.

Second US organized market to do so, and third in the region, after NY(ISO) and Ontario (IESO).

With HQ there as well, it’s actually quite a large coal-free chunk of grid.

What will be interesting is the extent to which offshore wind and imports from HQ will be able to materialize according to plan. OSW is having a hatchet being taken to it in the US currently, and imports from HQ into NY and NE have been way down recently while big new lines are also built.

Not exactly in the ISO forecasts, but very much supported by state policy has been the rapid expansion of behind the meter solar in New England. Really taken the edge off of summer days in particular, although also susceptible to smoke from Canadian wildfires.

Overall this isn't the W you think it is; New England still leads the nation in heating oil consumption by a large margin.

Nearly 2M households in New England heat their homes with oil (usually boiler, sometimes furnace). For those unfamiliar, a tanker truck comes by your house every couple of months and pumps diesel fuel into a tank down cellar, which literally gets burned like a flamethrower to boil water to heat your home. It's dirty but keeps your home toasty warm when it's -20 outside.

Maine in particular has very little natural gas infrastructure. Electric is impractical as New England winters are cold as balls and the houses are usually old and not that well insulated.

  • gbear605 14 hours ago

    Electric is extremely practical - I know a lot of New Englanders who have replaced oil burners with heat pumps and made back the investment quite quickly and warmly (it’s easy when a fill up of oil can cost close to a thousand dollars, and you will probably need two in a winter). Insulation helps a lot of course, but the main difficulty is just the upfront cost, time, and structural issues with houses that don’t have central air.

    • jabl 13 hours ago

      My father replaced oil burning with an air-water heat pump. That is, the heat pump heats water that circulates in the same pipes and radiators that were used previously. Apart from installing the heat pump in the boiler room, no other changes in the house were necessary.

    > For those unfamiliar, a tanker truck comes by your house every couple of months and pumps diesel fuel into a tank down cellar

    Huh, how un-insulated are those houses really? I grew up in an area with climate slightly colder than New England, and our house was heated with an oil boiler (not literally boiling, it was just warm water circulating in the radiators, not steam). Consumption was about 1000L per year, and the tank was big enough that one fillup per year was enough.

    Since replaced with a heat pump, FWIW.
