Summary
The energy transition conversation focuses on what connects to the grid. Far less attention goes to whether anyone is coordinating what those assets do once connected. AI training runs swing hundreds of megawatts in seconds as GPUs checkpoint and restart a profile that looks like a generator tripping offline. At distribution level, millions of inverter-based resources create localised variability that overwhelms individual circuits even when aggregate models look healthy. The planning tools in use today were designed for neither problem.
Host Bridget van Dorsten is joined by Kay Aikin, CEO and Founder of Dynamic Grid, energy engineer, grid architecture advisor to the DOE-supported GridWise Architecture Council, and contributor to the UN Environmental Program's building decarbonisation work. Kay unpacks what an AI training facility actually does to the grid with full GPU load for hours or days, then a drop to ten percent in seconds during checkpointing. She talks about how at the scale now planned, the Stargate project in Texas alone could represent ten percent of ERCOT disappearing in four seconds. The behaviour is stochastic and cannot be modelled with traditional statistical tools. At distribution level, virtual power plants responding to wholesale signals without circuit-level visibility can create competing oscillations, the kind of emergent dynamics that contributed to the Spanish grid failure.
The proposed fix is an AI controller at the substation, sending price-based signals and flexible operating envelopes to large assets and VPP operators, giving them twenty-four-hour forecasts and real-time circuit visibility. Total cost: under a hundred thousand dollars installed. The reason it isn't everywhere is cost-of-service regulation. Utilities earn returns on deployed capital, so a million-dollar transformer replacement is more profitable than software that eliminates the need for it.
Without new approaches, rebuilding the US distribution grid could cost up to ten trillion dollars by 2040. Kay is developing grid utilisation metrics with regulators in Maine, Virginia, and Maryland to incentivise extracting more from existing infrastructure. The episode closes on the need for distribution system operators and the affordability death spiral that looms if the structural incentives don't shift.

| 0:07.0 | we're talking $10 trillion in the U.S. to rebuild. |
| 0:11.0 | Tell us about the state of grid planning when an operator says we don't know how to model what you're doing. |
| 0:17.0 | The more affluent will leave the market. They'll put their own solar cells up, they'll put |
| 0:23.3 | EV, they'll put storage, and they will in effect grid defect. Who's going to be left holding |
| 0:28.4 | the bag is going to be those who can't do it. |
| 0:31.5 | The Welcome back to the interchange recharged. I'm Bridget Van Dorsden. And if you've been following along with the show, you've definitely heard us land on the same point more than once, which is the thing that strains a grid isn't simply how much power a new load draws. |
| 0:56.3 | It's also the swing, the sudden shift from drawing heavily to drawing almost nothing in a fraction of a second. |
| 1:02.9 | And this is what destabilizes frequency of the grid. |
| 1:05.6 | This is what keeps grid operators up at night. |
| 1:08.2 | And it's not just AI that's causing it. |
| 1:10.4 | The grid is being hit from |
| 1:11.7 | multiple directions at once. We do see data centers as a really clear example of large loads |
| 1:17.4 | connecting at the transmission level and putting pressure on the grid in terms of scale and volatility. |
| 1:22.7 | But there are also millions of small devices like EVs or rooftop solar that are connecting at the |
| 1:28.7 | distribution level as well and putting pressure on the grid in a similar way. |
| 1:33.2 | They are individually small but collectively create really unpredictable and localized variability. |
| 1:40.3 | And what's missing here is that nobody has built the intelligence layer that manages all of this together. |
| 1:46.2 | Today's guest has spent years mapping exactly where that missing layer needs to go. |
| 1:50.9 | Kay Aiken is the founder of Dynamic Grid, but also so much more. |
| 1:54.5 | Kay, welcome to the show. |
| 1:55.8 | Thank you for having me. |
