The question
Looking back at 2026 so far and forward to what comes next, what has surprised Shayle Kann, and what is he watching?
The answer
There is no single thesis here, and it would be a distortion to supply one. The episode is a short producer-led roundup: eight questions, eight separate answers, with the host as the only source. If anything recurs it is a habit of mind rather than an argument. Repeatedly Kann declines to give the headline cause the credit, and points instead at something slower and structural underneath it.
03The argument
The answer with the most reasoning in it is the first. Kann expected community opposition to data centers and did not expect it to arrive this fast or to be this bipartisan, with versions of a pause or moratorium now in both New York and Texas and, as he reads it, President Trump as the notable voice saying not to worry. His prior was that opposition would come mostly from the left, and part of it does, most sharply from Bernie Sanders, who responded to Dario Amodei’s public argument for pacing AI development by saying pacing is not enough and it should stop. But the right did not line up the way a crypto-friendly, libertarian-leaning coalition would suggest, which leads Kann to conclude that opposition is not really a partisan issue at all. It is a local one, sitting on top of a more general anxiety about AI. Asked whether all this slows the buildout, he says yes relative to a no-guardrails counterfactual, and immediately bounds it: Texas will still build a great deal, delays of six months to a year are realistic and five years is not, and the constraint on frontier AI, if one comes, will be something like a regulatory body rather than an inability to build data centers.
The same discipline about attribution runs through his answer on the war in Iran. He sees no good evidence of a large direct effect on electric vehicles. The correlation between fuel prices and adoption is weak to begin with, and the price move was smaller than expected: talk of $200 oil at the outset, roughly $100 at the time of recording. The sales data points elsewhere anyway, with the US down 21% because the tax credits went away, Europe up 29% in line with its existing trend, and a doubling in the rest of the world. Whatever the war did in the US was swamped by the incentive change; whatever it did elsewhere at most boosted a trend already underway. The effect he thinks is genuinely underreported is slower and not about prices at all. Between the Russia-Ukraine war and this one, Europe has become serious about sovereignty, visible so far mostly in defense spending but working its way into energy strategy, with a durable tailwind for anything that can be produced domestically or regionally rather than imported.
The forward-looking answer he has actually done arithmetic on is the one worth watching. The question is whether a data center and a utility will announce a tariff that substantially subsidizes everyone else’s electricity prices, and he says the math works, but only under a specific combination. Rates are set across a whole territory, so a large utility cannot direct the benefit at the county hosting the project; the subsidy gets diluted across too many customers to notice. Shrink the utility and it concentrates. His illustration is a roughly three-gigawatt peak system taking on another gigawatt of load, where the revenue and margins expected from a gigascale data center could fund a very large subsidy, possibly approaching the Ohio proposal to take everyone’s prices to zero, though he does not expect it to go that far and names 20% or 50% without committing. The catch is that the same smallness makes the case rare: you need a site, and you need to energize a gigawatt-scale load on a three-gigawatt system quickly enough for the subsidy to matter, which he calls a unicorn set of circumstances while noting that things of that order are already happening.
On solar he is making a forecasting claim rather than a physical one. A recent industry forecast reads this year’s strong build as partly a rush to beat the tax credit expiration and projects flat volumes for the rest of the decade; he is at high confidence it rises instead, and expects record volumes each year for five years. His reasons are that generation is needed more urgently than capacity, that solar is fast and deployable, that domestic manufacturing is expanding, and that its cost pressures are ordinary ones shared with everything else rather than the specific supply chain congestion afflicting gas. Then he undercuts his own contrarianism: forecast notwithstanding, he thinks the market already understands this. The related segment on commercial and industrial solar shows the limit of the optimism. That segment is stuck between two business models, unable to standardize the way residential can and unable to spread transaction costs over a large project the way utility-scale can, and reviving it requires both better relative economics, a premise he audibly doubts, and a radical cut in soft costs he thinks would have to come from automation. His closing hot take applies the same patience to the grid: utilities move on multi-year regulatory planning cycles, those cycles only started turning a couple of years ago, and once the momentum exists the system can build a great deal more than the “grid can’t keep up” narrative allows.
04What you need to know first
- Tariff
- In utility language this is the rate structure a regulator approves for a class of customers, not an import duty. It applies across a utility’s whole service territory, which is precisely why the data center subsidy idea works only for small utilities.
- Behind-the-meter generation
- Power generated on a customer’s own site rather than taken from the grid. Data centers are turning to it to avoid waiting for grid capacity, which is what created the opening for fuel cells and reciprocating engines.
- Commercial and industrial, often “C&I.”
- The middle market of offices, warehouses and small industrial sites, between rooftop residential and utility-scale projects. Its economics are the subject of the solar segment.
- Integrated resource plan
- The multi-year planning document a utility files with its regulator setting out what it intends to build. The length of that cycle is the whole basis of Kann’s argument that the grid looks slower than it will turn out to be.
05Details worth keeping
- Air permitting is emerging as one of the two or three real barriers to getting behind-the-meter generation built, and is part of why fuel cells are winning where they are.
- The selection criterion for data center power right now is operating history. Every gas turbine that can be bought is being bought, and the next tier is whatever has a lot of operating data behind it: reciprocating engines, and Bloom Energy’s fuel cells.
- Bloom is Kann’s pick for the underreported story of the year, with the caveat that it cannot be called an underdog at a roughly $50 billion valuation. The arc is a long one: founded before the first clean tech boom, rode it up and down, went public, sat as a small-cap company for years, and is now taking large orders from Oracle and others.
- Kann names water use as one of the main reasons the public objects to data centers while calling it possibly a false issue.
- Most new US solar projects now include batteries, which is how they acquire the capacity value solar alone lacks.
- Kann’s generic advice on solar forecasting: over roughly twenty years, US and global forecasts have consistently underpredicted deployment, so betting the over on the dominant forecast may be the safest bet in electricity.
06Claims worth citing
All figures as stated on 2026-09-17. This is a market-commentary episode and almost every number in it is volatile: an oil price given as of the recording, year-to-date sales figures, a market capitalization, pending state moratoria and a forecast published the week before. Treat everything here as a snapshot and re-check before repeating.
- Oil hovering around $100 a barrel at recording, against talk of $200 at the war’s outset. Kann
- Electric vehicle sales this year against last: roughly doubled globally outside Europe and the US, up 29% in Europe, down 21% in the US. Kann
- The US decline is attributed to the expiration of the tax credits, “mostly.” Kann says explicitly there is no good evidence the war in Iran drove any of these numbers. Kann
- Versions of a pause or moratorium on data centers exist in both New York and Texas. Kann
- Bloom Energy at roughly a $50 billion valuation when he last looked, having reached about $80 billion at one point. Kann
- Data center delays in Texas: six months to a year plausible, five years not, driven by a process Governor Abbott pushed through. Kann
- A solar capacity forecast published the week before recording, credited to SEIA and Wood Mac and expanded by neither speaker, projects US volumes flat for the rest of the decade after a strong year inflated partly by tax-credit timing. Kann says with high confidence it will rise instead, and expects record volumes in each of the next five years. forecast attributed to SEIA and Wood Mac; the dissent is Kann’s
- The data center subsidy case: a utility with roughly a three-gigawatt peak taking on about another gigawatt of load. Kann says the math supports a large subsidy, floats 20% or 50% without committing to either, and describes Vivek Ramaswamy’s Ohio proposal to take prices to zero as unlikely to be reached. This is Kann’s own unpublished arithmetic. Kann
- Grid build-out forecast: two years from now, the US will be adding more capacity per year than in any year since, he estimates loosely, before the turn of the century and probably some decades earlier. The bound is explicitly uncertain in the original. Kann
- Bernie Sanders responded to Dario Amodei’s argument for pacing AI development, which Kann says Sam Altman and Elon Musk agreed with, by saying pacing is not enough and development should stop. Kann
07Where it’s contested
- There is no guest and therefore no counterparty. A producer asks the questions and does not push back on any answer. Every judgment here is one investor’s read, delivered in a format with no adversarial check, and Kann identifies himself at the top as an early-stage investor at Energy Impact Partners. He names public companies, including Bloom and Oracle, without stating any position in them.
- Kann flags his own prior as wrong. He expected data center opposition to come mainly from progressives and says it did not break that way, which is the rare case of a forecaster marking his own error in real time.
- The Iran-war attribution is a negative finding, hedged. He says there is no good evidence of a large direct effect, that the US signal is swamped by the tax credit change, and that the non-US effect is at most a boost to a pre-existing trend. Anyone citing this episode for “the war moved EV markets” has it backwards.
- His solar contrarianism is immediately qualified. Having disputed the published forecast at high confidence, he adds that he thinks the market already appreciates the higher number, which substantially reduces what the disagreement is worth as a trade or a planning input.
- The C&I solar case rests on a premise he doubts mid-sentence. He says commercial electricity prices are rising a lot and solar is getting cheaper, then appends an audible question mark to the second half, and calls better economics necessary but not sufficient without automation cutting soft costs.
- The subsidy tariff is arithmetic, not a prediction. He says the math works and that enacting it involves considerably more complexity, and describes the required conditions as a unicorn set of circumstances, while noting projects of that scale are already happening.
- The backlash claim is carefully bounded. He expects real delay to the data center buildout and explicitly does not expect it to slow frontier AI, pointing instead to a possible regulatory body as the more likely brake.
- The grid prediction carries its own uncertainty in the original. He reaches for a comparison year, does not land on one, and offers a range instead.
