The US Had a Big Battery Boom Last Year (wired.com) 47

The United States installed a record 57 gigawatt hours of new battery storage on its electric grids in 2025, a nearly 30% increase over the prior year that arrived even as the Trump administration cut tax credits for wind and solar in last summer's One Big Beautiful Bill.

The figures come from a Solar Energy Industries Association report published Monday, which also projects the market will grow another 21% this year by adding 70 gigawatt hours in 2026 alone. Battery tax credits themselves survived the legislation largely intact, and the majority of last year's new installations were stand-alone systems not tied to specific solar projects.

In Texas, solar met more than 15% of electricity demand throughout the summer and beat out coal for the first time, and the SEIA report predicts the state will overtake California this year in total deployed storage. Supply chain restrictions reinforced by the bill and project cancellations could slow the pipeline this year, the report cautions.

      What's missed here is that China installed more than that just in December, 65 gigawatt hours. They also installed more solar last year than the rest of the world combined, and opened more nuclear plants than the rest of the world has opened in all the years since the 1970s combined.

    I remember power stations were about the price of $2/watt for a while, and heavy, then stayed at $1/watt for maybe 5-7 years. Now, I'm seeing that drop to 50 cents per watt for name brands like Jackery.

    This is a very good thing overall. Not just for powering small items when power is out, or on a trip, but there are a lot of cities that tack a fee on the time of day of power use, so if one charges a battery bank when those fees are not applied, and just used power from the battery from there, it can pay for the battery bank after a while. Done right, it means we don't need as much base load, with solar and wind handling everything in the daytime.

    My next RV build, I'm definitely going to stick a few thousand watt-hours of batteries, with the ability to feed the battery bank via shore power, a generator, or maybe via a second alternator. This way, I can run the A/C regardless of state, being on the road, dry camping, or camping at a campground. If power sags, or is really dirty at a campground (perhaps low voltage when the class "A" big rigs come in with 5+ air conditioners up top), the lower voltage isn't going to burn out compressors, and is still usable for battery charging.

      "...it can pay for the battery bank after a while."
      That "while" needs to be short, otherwise there is no financial benefit. When you are at a breakeven point, all you've done is paid someone else those same fees, then assumed the storage, maintenance and liability of additional equipment.

      " Done right, it means we don't need as much base load, with solar and wind handling everything in the daytime."
      Where "done right" means done FOR us, not BY us. That's the point of public utilities.

      • "A few thousand watt-hours" should definitely "run the A/C", hell that like several e-bikes worth! Hopefully no one else will suffer when your batteries explode.

        Oh look, some bullshit from a know-nothing who has no experience.

        Everyone is using LFPs in their RVs now, because they are cheap AF. The question is, why do you imagine the consumption of an e-bike is relevant to that of an air conditioner? Most of them run over 1000 watts, most e-bikes are around 250-400. If you knew anything about any of this you wouldn't have written your post at all.

        Having centralized battery storage is cool, but you know what else is cool? Having power during an outage.

      • I recommend brushing up on battery chemistry. LiFePO4 doesn't explode, and it can handle a lot of cycles.

        This isn't a new setup. I have a co-worker who has exactly this, with a Victron 4000 watt inverter with two power inputs. His class "B" van kept his house powered up during a power outaged due to a fallen power line. I highly recommend looking at lithium battery chemistries. Not all of them go boom when you look at them funny.

  • A "Big Battery Boom"? That's kind of ambiguous, made me wonder if there was a massive lithium-battery explosion or something.

      That happens as well, but less and less often. And these installations are designed to deal with that with minimal damage. Since these batteries are stationary, other tech is also in use.

  • Is that what happens when they catch fire?
  • 1 hour of storage for the US is 450 GWh's. So this is roughly 7.6 minutes of storage.

We can predict everything, except the future.
