I’d refer to the source studies, but at $9,990 per region… Ms Pickerel’s overview seems plenty informative for me.
Regarding EMEA:
> Grid-scale battery storage costs are now decisively cheaper than gas peaking across the region. [and price will fall another 33% in the decade ahead]. This shift means storage is displacing open-cycle gas turbines on cost in every gas market across the region, marking a significant structural turning point for power system planning across both the Gulf and Africa.
The analyst’s bottom line:
> From Latin America to Asia Pacific, the combination of falling storage costs and world-class renewable resources is closing off the economic case for new gas peaking capacity, while long-term contracted renewables increasingly set the ceiling rather than the floor on power costs.”
Heady times! For all the gnashing of teeth about regulating our way out of combustion-based production—it’s ultimately superior technology that’s ripened to displace gas peaker plants, no arm-twisting required. “Not with a bang, but a whimper”…
I'm struggling to understand the numbers here. How does a fall of 33% on $37 make it $80?
> Four-hour storage reaches $120/MWh in 2026 and is forecast to fall 33% to $80/MWh by 2035, cementing its role as the enabling technology for solar and wind integration.
Cheap or not, solar isn’t dispatchable on demand, so in and of itself it doesn’t replace the role of a peaker plant. But now that the big batteries are a viable thing, solar-plus-battery is feasible to handle the parts of the demand curve that required open-cycle gas plants before.
4 hours at a time hopefully buys you your way through such a peak, even if it doesn’t get you through weeks at a time… and presumably you can top it up from base load after demand peaks for the day, right?
In the equatorial and desert regions they’re talking about, I think both seasonal supply changes and demand profile might be more consistent than, say, dreary cold parts of Europe..
But no one is claiming that there will only be 4h-storage
(1) ordinary diurnal variation (overnight, lets say 12 hours)
(2) extremely unfavorable weather (see https://en.wikipedia.org/wiki/Dunkelflaute)
(3) annual variation (you might get 3x the sunlight in summer than winter? do you build 180 days of storage or do you overbuild solar systems 3x and get Casey Handmer to dream up something useful to do with that excess energy that doesn't have a stupendous capital cost?)
The "have a natural gas backup plan" is worse than people think for a lot of reasons, in terms of the laws of political science and economics you're going to find that that tail winds up wagging the dog, the whole market will get designed around the needs of those turbine owners, it's going to cost the same if they are running turbines for 5 minutes a year or 20 days a year, and ultimately you're never going to get rid of it. If you really plan to run the system 5 minutes a year what are the odds it will really work when you need it? You have to not just support the turbines you hardly ever use, pipelines you hardly ever use, drilling and storage operations for gas, etc.
what about the variation regarding winds?
Otherwise you need to deal with long distance power transmission across many political jurisdictions, or local generation for night or other low-solar times. To my mind, nuclear base load with solar and batteries used for things like charging cars or demand-shifting probably makes more sense. It's really a shame that we mostly withdrew from building nuclear plants for the past three or four decades; instead we have reached the point where we have to re-learn how or recreate the tooling needed to build them and they are still too damn expensive.
What's the ecological impact of constructing all these batteries?
Let's see some actual numbers.
Gas is 0% recyclable.
What's the runoff from the chemical processing to make the batteries like?
Or does it not matter if you poison great swathes of China?
Recylable is important because it means we don't have to mine as much.
Neither of these assumptions are based on anything other than "That's the number we had to put in to the model to get the conclusion we want".
I can't comment on the cost of Gas Turbines.
But the opposite is true for batteries.
IIRC there are something like 3 companies on earth that can make gas turbine blades, as it's a particularly difficult process, and they are sold out for the foreseeable future. New capacity is severely constrained and cannot meet demand.
Battery production is being invested in heavily. There are new types of batteries (like sodium ion) that are extremely relevant to the article that it barely even mentions. The pitch for those is of course no lithium, better temperature ranges, less need for cooling/heating them, much better fire safety, better durability, etc. This all adds up to lower cost when done at scale. That all adds up to a lot less cost for especially grid storage.
I agree the 33% number is meaningless. It's probably too conservative. The article actually does not talk about new battery chemistries like sodium ion. And given that large scale factories are already producing those by the tens of gwh, I think that's more than a little oversight. Additionally, there are learning effects that explain the large differences in prices between markets that the article mentions. Those are optimizations that countries have yet to implement. Some might not get around to that any time soon (like the US seems a bit of a basket case on cost/efficiency for a lot of things).
Because of the improvements in battery cost relative to the stagnating improvements in gas turbines, gas turbine manufacturers are going to be conservative in investing in new production capacity. A lot of companies that say right now that they are going to want to buy gas turbines might no longer want to in a few years. For example the low cost and ready availability of solar+battery might be persuasive for some. Investing many billions in new production capacity that won't come online until some time next decade is highly risky if the projected demand could evaporate. The reason there is a shortage is that that's what they thought five to ten years ago as well. So, it's easy to predict that turbine shortages might continue to exist.
But that's just the short term.
More importantly, I believe that manufacturers are more confident in the long term future of demand for batteries so are willing to continue to invest. People are going to be buying electric cars 10 years from now. The demand for gas turbines in 10 years seems a lot more murky.
SpaceX has promised to start making turbines, which would bring their price down. But it's an Elon Musk promise, so how much weight do you put on it?
(Though I really want to see a fast reactor coupled to a supercritical CO2 or helium brayton cycle turbine!)
Zero.
And I really mean zero, not a negative value. That is, when Elon Musk promises something, it doesn't mean he won't do it, it means that it is just as likely to do it as if he didn't promise anything.
I don't understand why people listen to him when it comes to predictions, he is as close to a random generator as one can get. Even analyzing his actions come with a lot of uncertainty, though not as much as what he says, some things are too big to hide. Being able to maintain such level of uncertainty is probably part of his success, he is like a poker player no one can read.
There have been some experiments with prefabricated construction, but you still run into the issue that shipping really big things is hard, as we've seen with wind turbine blades. Robotic construction might make a dent at some point, but it still seems to be basically embryonic.
That said, I doubt the cost of either of these technologies is driven so much by the technologies themselves so much as it is our ability to manufacture and install large volumes of them at scale. Presumably it's easier to mass-manufacture batteries in a big factory and then ship them to the site than it is to construct each gas peaker plant on location, and moreover it's probably easier (i.e. cheaper) to scale up the manufacturing process for batteries than it is to scale up the construction process for peaker plants.
Yes, and this is the assumption that the comment I replied to seems to disagree with. I think the assumption is right and the disagreement is wrong.
> That said, I doubt the cost of either of these technologies is driven so much by the technologies themselves so much as it is our ability to manufacture and install large volumes of them at scale.
Deployment is part of the learning curve.
I think you're agreeing with me (and disagreeing with the comment I replied to) here :)
> Every time the global cumulative battery production has doubled, the price has dropped by roughly 19%.
There are only a handful of gas turbine manufacturers left, with a manufacturing backlog of half a decade.
It is exceptionally obvious battery manufacturing will only continue to scale (TAM is global EV and stationary storage market), and gas turbine builders will hang on until the economics turn, which they have. Regardless, these trajectories will hold unless something exceptional occurs. Is it likely we’ll build more batteries faster? Yes. Is it likely these are the last three major gas turbine manufacturers to exist? Also yes. Last call for buggy whips.

1. Because there is a lot of pressure for them to go down, in literally every form of technology, be it phones, robots, drones, EVs, ... Turbines are also important, but they have had that pressure for decades and are relatively finished. Any further improvement will give diminishing results outside of specialized applications and demands
2. Because the technology for batteries is relatively open ended in comparison. Turbine prices are mainly about how that steel can be precision engineered and while there is some innovation at this front, the gains from that innovation have slowed for a while now. With batteries however the race is still very open and it would not be naive to assume some new chemistry will be found that reduces the cost and energy density drastically.
I don't know the economics around precision engineering well enough to intelligently how high demand impacts the manufacturing cost, but I could imagine it behaving slightly different than the cost of simpler processes, especially since good CNC machines are hefty investments.
China leads the world in battery manufacturing, it's not really so hard in an absolute sense, but gee do you have to get the cost down and get the quality up so you don't have batteries blow up because of manufacturing defects.
To make gas turbines though you need to get the last bit of performance available out of metals, manufacture parts with punishing tolerances, and do it with high quality so turbines don't blow up because of manufacturing defects. At this point in time China cannot make competitive gas turbines. China's COMAC C919 airliner is 100% dependent on western engines for instance.

Here's a prior take on this topic:
The big stories from the last year in electricity [2026-04] https://www.volts.wtf/p/the-big-stories-from-the-last-year
Global Electricity Review 2026 https://ember-energy.org/latest-insights/global-electricity-...
TLDR: Every where but some parts of the USA, solar + battery is the cheapest source of new power generation. Tariffs and subsidies continue to prop up gas generation. 40% YOY drop in battery prices!? Solar + battery is still on the cost learning curve (no where near plateau), whereas gas (extraction, turbines, etc) plateaued a while back.
--
That episode (and Ember's report) looks back at 2025.
So it couldn't account for this year's increased prices and volatility for gas, or data centers increasing the demand for gas turbines.
Globally, solar + battery adoption continues to accelerate. In the USA, big tech forfeited their climate pledges (choosing to use gas) and new solar + battery continues to be blocked by our constipated connection queue (to the grid).
Those turbines aren't great for longer periods, they're pointlessly inefficient if you don't need their ability to peak for short periods.
An open-cycle gas turbine is the "simple" configuration that draws in air through a pressurization stage, into a combustion chamber for fuel combustion, producing high-pressure hot gases that drive a turbine and generate power, with exhaust gases released into the atmosphere.
In other words, there is no recovery of heat from the exhaust, it's basically an aircraft jet engine core mounted on the ground and connected to a generator. They aren't very efficient but they are compact, relatively cheap, and quick to spin up during peak demand times.
In a healthy grid with a diverse generation mix, batteries are almost certainly the perfect option for peak demand handling. The problem is that many grids are not healthy or do not have very diverse generation mixes.
You are effectively borrowing from yesterday (or last hour) to pay for today with batteries. Which is amazing, until it isn't. The Texas winter crisis comes to mind as an example where batteries would be regarded with intense derision. I think the current capacity market accreditation process is massively underrepresenting the tail risk of a black swan event. Four hours of battery storage should not be in the same room as a gas turbine when we are talking about capacity and multi-day emergencies.
And grids can actually be connected together via cables now. The cliche is that solar panels don't generate at night. But if you connect grids via a long cable running east to west you can actually have solar power at night. And when you connect them north to south you can have solar power on a dark winter day as well. And when you add batteries to the mix (on both sides), you can keep those charged as well and use that power regardless of what time or season it is.
And that's ignoring wind (on and offshore), hydro, nuclear, and other clean forms of power that we currently don't use at scale (geothermal, fusion, etc.). If you add all that to the mix. And cables. And lots of battery. Grid connected car batteries, balcony solar, and all the rest, you end up with a lot of capacity.
Gas power is not going to way. But we probably already have too much of it and it shows in the poor utilization of existing turbines. Ironically, adding more gas turbines to the grid only makes that poor utilization worse for owners of these plants.
Maybe there's an argument for managed forests for charcoal energy production too. That would technically be carbon neutral.
Gas is not cheap, it basically doubles your costs.

> For its part, China – a battery manufacturing powerhouse – has no such supply chain issues. It dominates global lithium battery production accounting for two-thirds of it. This relative strength gives it the confidence to relentlessly amplify its BESS footprint as evidenced in the capacity build-up between 2021 and 2026.
> In fact, China’s battery storage build-out has no global parallel thanks to this one factor alone, according to Ember. It estimates that nearly all (i.e.149.8 GW) of China’s “new energy storage” consists of lithium-ion batteries.
> In terms of the future, following a June update to its 15th Five-Year Plan, China is now aiming to deploy 300 GW of new energy storage by 2030. That would keep the country’s BESS industry progression, that outgrows all other countries combined, firmly on track.
(battery storage printer goes brrr)
Gas is far, far cheaper than building ~£1T worth of battery storage. Even if prices dropped, you are still looking at multi-hundred billions, and you still need the renewable capacity on top of that.
Arguably if we had spent the £100bns (in subsidy and transmission upgrade and curtailment costs) we've already spent on renewables on nuclear instead we would have a very clean grid, even at crazy UK nuclear build prices, and stable electricity prices.
But ok, 30 million homes, 100kWh storage each, that's 3000 GWh
A 100kWh battery is about £25k, less than 1/10th the cost of the house, and less than the average new car
That doesn't seem unrealistic.
The cost of those last few percent is absolutely eye watering. The current plan to get it to 100% net zero is by having gas for the final 5% then using carbon capture and storage to offset the emissions.
Or indeed when petrol runs out as happens occasionally (in 2022 most recently). Of course there's also the problem of gas supplies stopping
[Gas is about 11-13x cheaper than renewables with externalities like grid restructure and volatility imputed.](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4028640) That’s not to say renewables don’t have their place in modern grids. In fact an optimal allocation is around 80% renewable in the UK. However, until battery storage becomes about 95% cheaper, it would be ASTRONOMICALLY expensive to make the grid 100% renewable. Trillions of pounds in the UK. An order of magnitude more expensive than just paying higher gas prices.
People often make the mistake of thinking that because wind and sun is free, the cost of energy generation is basically free. Those people don’t understand how many fixed and marginal costs there are. If you’re interested, the paper above provides good insights into those costs.
Well, other than destroying the planet, but hey, let's just hide those costs.
If your going to burn the power turning it into hydrogen then you save a shitload of that power by putting it in batteries instead.
Storage of hydrogen in underground caverns is demonstrated technology.
but hybrid cars are saddled with a maintenance heavy complex system that isn't used much.
nowadays we know the solution is just a bigger EV battery.
Looks like 5 year reliability: ICE > non-plugin hybrid > pure EV > plugin hybrid
But EVs seem ok 5+ years
I found this article interesting:
https://autoedgeview.com/ev-reviews/consumer-reports-ev-reli...
Biodiesel or biomethane looks at first glance to escape this, but it has serious other costs.
What’s with the forecasts going as far out as 2060?? Given the scale of changes we’ve seen in just the last 10 years, looking forward 34 years seems absurd, and to still only expect a 16% drop in cost?
That being said, anyone who has predicted the future prices of renewable energy seems destined to look a fool.
This seems to be specifically in reference to "gas peakers" which are on-demand gas turbines used to pick up slack in the main grid during peak usage. They typically only run for hours at a go and commonly on very hot days when ACs drain the grid. In those use cases, batteries could be a viable replacement. They're not necessary charged by solar but by the main grid overnight.
Vs. longer-duration needs, like a couple calm (bad for wind power) dark (bad for solar power) weeks in winter - you will need combined-cycle turbines or something for those, because installing that many batteries would cost too much.
https://en.wikipedia.org/wiki/Gas-fired_power_plant#Plant_ty...
The most important driver of power system costs is "firm capacity"; a MW of four-hour battery might be 10%-50% as valuable as a MW of gas turbines given that the latter will run for 100-1000 hours per year when the batteries are empty and the prices are much higher. This is true on the grid or behind the meter.
solar panels & batteries in the texas oil patch or sw or mexico... morocco or spain.. australia...
everything associated with datacenters does not pay tariffs. tech leaders could lead the way here and not only provide AI but also potentially take big steps towards solving the climate crisis.
certainly cheaper than putting panels in space. (do the math)
Next is EVs as energy storage. People buy cars anyways. An EV looks, works, functions and smells exact like a gas car. Some might even say it smells better. Its not like going from horses to cars, nothing that radical. With EVs, we add a TON of storage. 20% or more solar production is curtailed, all of this can go to EVs. EVs can supply power back to the grid. Or power home throughout the night.
Finally, add BESS if needed.
28% of trips are under a mile, 52% under three, 64% under five, 79% under ten, 93% under twenty-five, and 98% under 50 miles. Only 0.8% of the trips are over 100 miles! EVs have humongous batteries, you can control the level of charge/discharge from the grid
People should be paid for using their EVs. They are after all providing critical, highly resilient infrastructure at no cost to govts and utilities. I don't think there is any compelling reason to make the super-billionaires like Warren Buffet richer.
Land for solar installs isn't close to free. My condo HOA won't even consider solar for any homeowner and the HOA won't approve a giant $50k/unit special assessment (we can't even get 40% of homeowners to vote for HOA elections... which are free).
Older buildings not designed for a solar roof aren't too easy to retrofit. My office window overlooks 2 parking lot structures that were recently retrofitted with solar and it took about 6 weeks for a relatively simple install. I'm pretty sure building owners will only install if they get a cut of the solar generation revenue (so the land isn't free) or if they are able to use it to offset tax or utility costs (also not free).
EVs as batteries are neat but... (1) most owners will likely splurge only for the $500 charger station not the complex electronics which allow the EV to charge the house/grid and (2) cars are frequently driven / parked at work during the peak charging time, so they would be unavailable to absorb the majority of the peak solar generation time.
Until there is a solar EV + charging story for dense housing (apartments and condos), I think most users in my area aren't likely to be able to adopt like you seem to think. Community Solar projects seemed nearly non-existent when I searched in 2018-2020.
I liked laws like the fcc(?) law years ago that said you could have a satellite dish and an HOA couldn't prevent it. we need more laws like it in favor of common sense/good over HOA nonsense.
The trips over a 100 miles are a much higher percentage of distance travelled. One 100 mile trips is the same distance as 33 three mile trips. if you look at distance travelled its dominated by longer trips on your numbers.
I assume your numbers are for the US where cars are more heavily used for commuting than anywhere else?
Persuade my city to install some sidewalks, please. I can't leave my neighborhood safely on foot.
I am more used to dealing with places that go too far the other way and think you should be cycling even if you have multiple suitcases to carry.
Expensive prime arable land in the UK is rentable for £200 per hectare per year. You can buy it for £20k a hectare (land value is far higher than usable value due to tax avoidance schemes -- nobody spends £20k on a field to rent it out for £200 a year)
But even if you buy 100 hectares of land for £2m, you then need to build your 60MW, which costs about £60m on top and generates 60GWh a year or £6m at 10p/unit
The land cost doesn't matter.
The point is the electric delivery problem is much cheaper if the power generation and the power delivery both happen within the same substation (eg in the same neighborhood). If the generation happens in rural Scotland but the consumption happens in London, then all of the transmission needs to be upgraded. The point of your parent's comment was to describe a trick to minimize additional transmission costs/development.
And London area land does cost, even if it is just borrowing a vacant building's rooftop.
I don't necessarily agree with your parent's comment, but I don't agree with your comment either.
Battery is load balancing not generation.
Put another way, you need the gas turbines for the two week dunkelflaute (winter doldrums). Given that you have the turbines already, when are batteries cheaper than running the turbines for a few hours every evening?
A more interesting question than the cheapest 4 hour solution. I think that answer might also be batteries soon.
Four hours isn't "doing a lot of work," it's the whole point of the article. It's not about dunkelflaute.
And what happens if you need to satisfy peak demand for more than four hours at a time (and you will)? You still need some generators or overprovisoned batteries.
