Earlier this month, I visited Ken and Carol Apaki. They live in a little town outside Columbus, Ohio.
They're retired now.
Carol worked in curriculum development. Ken was an engineer. And according to Carol, Ken still has an engineer's way of keeping track of things. Everything, everything ends up in a spreadsheet.
He had the grandkids. What was it when you had them do a chart, all of our grandkids? Their height? Oh, yeah, their height, how much they grew from year to year. Because he's been measuring. We've got a big board.
We've got a board with everybody's measurements on there for 20 years.
All 13 grandkids, their height by year, in a spreadsheet on their computer.

Chapter 2: How are electricity prices affected by data centers?
With tech companies spending hundreds of billions of dollars on AI, data centers have kind of become the thing in the U.S. economy. We are spending more to build data centers than we spent to build the entire interstate highway system.
But along with that growth has come questions about where all the electricity to run those incredibly power hungry data centers is supposed to come from. Today on the show, data centers and electricity. What all the AI investment might mean for all of our electricity bills. And what, if anything, we can do about it.
So investment in data centers has been this giant economic story. We're talking hundreds of billions of dollars expected to add up to trillions over the next five years. But, you know, Keith, sometimes this whole thing has felt super abstract, right? Like it's just a line on a graph called data centers and it's going up and up and up.
Totally. And this is honestly part of the reason I wanted to go report this story in the first place, right? Like I wanted to actually go look at some data centers. And Ken and Carol offered to take me on a little tour of their corner of central Ohio. All right, so tell me the plan.
Okay, we'll start here in Granville and then go over to Alexandria and then an existing data, new data center.
Jeff, I don't know if you know this about me, but once upon a time, I lived in Ohio for a year and a half. Best year of your life. Well, it is where I met my wife. And at first, the landscape, right, where we were, that landscape looked kind of like the rest of the state. This to me is what it feels like driving across any part of Ohio.
It's like flat land, farm, trees, a little snow on the side. But then, six or seven miles from Ken and Carol's house, complete change.
Okay, and you come out of the trees and what do you find? Cranes and construction and a data center.
Then, a little ways down from there, another data center.

Chapter 3: What is the connection between Ken and Carol's electric bill and data centers?
I think everybody understands the product. incredibly complex to deliver that product.
Marc says going back about a decade, he started hearing from data center developers who wanted to get connected to power. Then in 2022, 2023, he started getting a lot of requests to connect a lot of data centers who wanted a lot of power.
If we do a 800 home housing development, that'll be, you know, call it a megawatt. But the data centers are clusters of 50 megawatts to 3,000 megawatts.
So just one of those bigger data center clusters he's talking about would use the same amount of electricity as the entire city of Fort Worth, Texas.
Now, it's worth pausing for a second to explain AEP Ohio's business model. It works like this. The state gives AEP Ohio a monopoly over delivering electricity in its service area. But to keep their monopoly power in check, AEP Ohio is not allowed to set their own prices. Instead, the prices are set by the government, the State Utility Commission.
If AEP Ohio ever wants to raise its rates, it first has to get permission from the commission.
The primary reason they're allowed to raise rates is because they've invested in their infrastructure, upgrading their power lines or building new lines and substations when they need to.
The grid supports everybody and everybody pays fair share. That's the crux of the model, has been for a long time.
And for years, this kind of social contract made sense. The infrastructure expanded little by little over time, and everybody paid for it collectively. But as more and more companies were asking to connect more and more data centers and get access to more and more power, Mark realized all this could kind of break the system and really raise prices for residential customers.

Chapter 4: What theories exist about rising electricity costs?
So as long as the data centers show up and say they're going to use That should offset the costs associated with the infrastructure build-out.
The new rules got approved by the State Utility Commission and went into place earlier this year. It's one of the first data center-specific utility rates in the country.
Mark acknowledges that residential customers will still pay for some of the infrastructure costs from data centers, but it should be a lot less now.
And using the data from Ken's spreadsheet of all his electric bills and talking to energy experts, we estimate that only about 10 or 20 percent of the price increases Ken and Carol saw were because of AEP Ohio. AP Ohio, though, they are just the local distributor. Their job is only to bring electricity the last mile to people's homes.
So if the problem isn't distribution, how are data centers making things more expensive? Well, the next place to look is one step further up the chain at what is called transmission. So not how electricity gets moved around on a local scale, but on a much bigger scale. The grid of giant power lines that connects power plants from one state to customers hundreds of miles away.
Cameron Ali is in charge of a big chunk of that grid of power lines across 11 states. When Cameron closes his eyes, he says he can visualize the whole thing. In your mind, is it colors or is it black and white?
Colors. Yes, absolutely. Every single voltage is a different color. What are the colors? Well, 765 kV is green because that's my favorite. 345 kV is red. And then 138 kV is black. And then we have lower voltages, purple and yellow.
Cameron works for AEP, which is the parent company of AEP Ohio. His job is to make sure that the multicolored grid that AEP owns stays up and running and to figure out what new red and green and black power lines need to be built to get all the electricity where it needs to go.
Cameron told us to think of the grid as like the highway system, but for power. If you want to send more power to new data centers, you have to build new lanes and new on-ramps and new off-ramps.
