Smoke Sends US Northeast Solar Power Plunging By 50% As Wildfires Rage In Canada (reuters.com) 90

Longtime Slashdot reader WindBourne writes: "A shroud of smoke has sent solar power generation in parts of the eastern US plummeting by more than 50% as wildfires rage in Canada," reports Bloomberg. "Solar farms powering New England were producing 56% less energy at times of peak demand compared with the week before, according to the region's grid operator. Electricity generated by solar across the territory serviced by PJM Interconnection LLC, which spans Illinois to North Carolina, was down about 25% from the previous week."

Not mentioned in the article is that the wind generator output has also dropped. ["Wind power also dropped to 5% of total generation so far this week versus a recent high of 12% during the windy week ended May 12," reports Reuters. "That forced power generators to boost the amount of electricity generated by gas to 45% this week, up from around 40% in recent weeks."]

If forest fires can cut PV output by 50%, what would happen in real disasters when a nation most needs their electricity -- especially as we convert from fossil fuels (stored energy) to electricity? This will hopefully have politicians thinking in terms of national security, as well as anthropogenic global warming, when it comes to western grids.

      Nukes can't cope well with forest fires either. They need a constant supply of water for cooling, and they need HVAC. HVAC filters get clogged up fast when the air is thick with particles.

      Same applies to many fossil plants and large industrial operations.

      Visibility can also be an issue as for safety reasons some stuff needs to be monitored visually.

      Really the only solution for keeping the lights on is to have good long distance transmission, so power can be produced well away from the fires.

      • Nuclear power plants have systems and plans in place for dealing with active on-site operation during an ongoing nuclear event, in which its assumed that there is radioactive particulate present and workers need to be partially or fully bunkered to limit exposure. Wildfires pose virtually no risk to nuclear plant operation, beyond the potential for offset transmission to be disrupted.

        Similarly thermal limits on cooling water are virtually always for ecological reasons, to prevent disruption to aquatic wildl

          In the event of a nuclear accident the plant shuts down as quickly as possible, it doesn't keep operating. No sane nuclear safety plan calls for other reactors to keep running if it can possibly be avoided, so the only situation where it would be attempted as a stop gap measure is when all other external power sources fail.

      Well, as soon as this appears on the Republicans' radar, the answer will be either to build a wall, or to sue. Depending on whether it's Trump or DeSantis.

      Trump will want to build a wall to keep the smoke out, and will claim he will charge Canada for it.
      DeSantis will want to Canada's "most favourable trading partner" status because for illegal dumping of smoke, and then sue.

      Technically coal plants wouldn't have this problem.

      Yes, they have the exact same sort of problem with natural and man-made disasters. Coal plants have to be located near rivers for cooling water and the same increase in cloud cover due to global warming that reduces solar plant output also brings lots of rain that causes flooding that can take out your coal plant.

      If you also consider terrorism then a coal-fired power station is located on one site that could be severely damaged with a single explosive device knocking out the entire station and requiring significant repairs to fix. Compare that to a solar or wind farm where the generators are spread over a wide area. The best you could hope for there with a single device would be reducing the capacity a bit by knocking out some panels or a wind turbine.

      So by all means consider national security when pushing for power generation since I think the conclusion will be to support more renewables with the exception of hydro.

      • So far the terrorism thing seems to be limited to a few gormless white supremacists shooting at substations. Cyber-attacks seems to be more of an issue. Maybe they can get the power stations to upgrade from Windows XP?

        Actually the renewables require storage to smooth out availability which is less distributed than coal generation and neutralizes the more distributed nature of renewable generation. Wind and Solar aren't really all that distributed anyway, especially wind. Sure you can have an ad-hoc small scale wind turbine but most of the gene

    This is just another anti-solar FUD story.

    Yes, it's an issue, but it's no different from a big weather pattern that reduces solar due to clouds over a large area. The solutions are the same as always: Expand the grid to be able to pull in power from a larger area, maintain a mix of renewable sources, and include storage in to cover shortfalls.

    We have the data for wind and solar production effectiveness throughout the country going back many years. And we can fairly accurately determine what it would have been going back a century based on weather records. So it's just a matter of running the data to see what we would need to have to ensure sufficient power supplies with different source mixes, storage options, and grid upgrades. Toss in cost estimates for all the options, and optimize it to get a plan.

    • Not only that but the impact is highest at peak output. Your peak output might drop by half , but energy for the day drops by ~20%. Everybody knows you have to over-provision with solar or wind, but it is not a huge impact to payback.

      • Peak demand is late afternoon, when solar power is diminishing as the sun goes down. More air for the sunlight to go through, so more scattering when the air is smokey. The solution is what it always has been - store the excess midday energy for the afternoon and evening.

        • Peak demand is late afternoon, when solar power is diminishing as the sun goes down.
          Perhaps at your place.

          For every other place: it is a completely different story when peak demand is.

          So: perhaps you want to look up when peak demand is at the place in question, and then tell us if you were right or wrong.

        • Peak demand is late afternoon, when solar power is diminishing as the sun goes down.

          Is that really peak demand? Or is is peak demand on the distribution network?

          All those residential systems are generating power that is used by the same houses, thus masking their own demand.

          Then, there is another issue with measurement of demand, that those residential solar systems are providing power to their neighbors, so reducing demand on the grid. It's possible to calculate this, assuming everyone has a smartmeter, but I suspect that this measurement is not normally done.

      This is just another anti-solar FUD story.

      Yes it is but it is a really stupid one because the solution to this problem is more solar and renewables, not less. If we can reduce and eventually eliminate our impact on global warming it will reduce temperatures resulting in less cloud cover and fewer forest fires.

      As far as war and disasters go solar and wind are far more robust than just about anything else because they are distributed. To take out a solar or wind farm you need devastation over a wide area. To take out a fossil fuel power station you only need to hit one building...and often that building is located near a river for cooling water which is more likely to flood than the tops of hills and on flat plains away from rivers where wind and solar are located.

      • Agreed. The other factor here is energy storage. That's the current Achilles Heel of renewables. It's coming, but we're still a decade or two away from grid scale storage that can sustain multi-day reductions like a week of 50% reduction.

        Wrong.
        Nothing stupid about it. It is important to see the issues with those that continue to push Wind/PV as the only answers.
        National security dictates that we have an energy matrix, not depend on just 1 type of energy (and wind/PV are BOTH dependent on the sun, which is easy enough to block).
        As to distributed wind/PV, that is NOT the case. The far left continues to push for utility level PV, which Ukraine, Texas and California has shown nicely that it is a fool's errand to do so. Instead, it IS good to distribute PV on residential buildings, along with parking lots, etc.

        Still the real lesson is to use ALL OF THE ABOVE within the clean energy category. That means nuclear, hydro, geothermal, wind, and PV. Down the road, perhaps tidal will be there.
        • by AmiMoJo ( 196126 )

          Of course it's stupid. The solution is more long distance transmission lines and more renewable energy. Nuclear plants can't operate properly or at all in these conditions either.

Fortunately, it is not at all easy to block the sun in a specified area for an extended period of time otherwise people would already have tried it.
