Key Discussion Points & Insights

1. Policy Backlash Against Data Centers

• [00:12] U.S. politicians—including Senator Bernie Sanders and Representative Alexandria Ocasio Cortez—have introduced a bill to pause new AI data center construction, citing soaring electricity prices as a key concern.
• Maine's recent legislative moves: The state's House passed a bill to pause most data center construction, with both Senate and governor support.
• Data points: In some areas, according to Bloomberg, electricity prices have more than tripled over five years near data centers.

2. Are Data Centers to Blame?

• [00:55] Jay Jayasira argues that data centers are being unfairly blamed for larger, long-standing grid problems:
  • "I think data centers are a factor, but to say that they're the ones solely responsible for higher electricity prices I think is perhaps misleading." (Jay Jayasira, 01:05)

3. The Real Issues: Years of Grid Underinvestment

• [03:20] Jayasira describes underinvestment in the grid:
  • Infrastructure often lacks upgrades, is vulnerable to storms, and new renewable projects can't connect easily.
  • Companies building data centers are investing in self-generation, e.g. on-site power plants.
• Solutions data centers bring:
  • "[Data centers] are...responsibly finding ways to acquire power...investing the money to build a co located generator that will serve the data center needs." (Jay Jayasira, 03:57)
  • Sometimes, data centers use gas or even small nuclear options to offset their demand on the grid. Excess power can be fed back to the grid.

4. Economies of Scale & Fixed Costs

• [04:44] Data centers can share or offset fixed grid maintenance costs, theoretically lowering per-customer rates as more electricity is used and more costs are spread across users.
  • "[Data centers] paying for fixed costs—maintaining power lines, clearing trees, building substations—these would be costs for the utilities, no matter how much power..." (Waylon Wong, 04:44)
• [05:16] Example: PG&E in California claims data centers helped cut electricity rates by 13% since 2024 by helping cover fixed costs.

5. Counterpoint: The Problem is Demand Spike

• [05:32] Philip Krein challenges Jayasira’s view, arguing that the sheer scale and speed of new demand from data centers is unique and problematic.
  • "Data centers are walking in and say, hey, we want 20% more capacity and we want it today. That's just not a normal situation." (Philip Krein, 05:48)
• [06:12] Explains that this surge monopolizes all future potential grid capacity, reflecting quickly in current rates.
  • "Data centers and computing basically are sucking up 100% of potential future capacity and that is getting reflected back into the current rate base." (Philip Krein, 06:12)

6. The Grid Can Grow—If Incentives & Approval Hurdles are Addressed

• Historical growth: U.S. grid scaled up dramatically (factor of 12) between the 1920s and 1970s, but slowed since the 1980s as efficiency improved and demand plateaued.
  • "The notion that we need to grow again by 20 or 30 or 50% is a little bit of a been there, done that kind of a thing." (Philip Krein, 07:03)
• Modern challenges: Growth now hampered less by technology than by complex permitting and fragmented regional systems.
  • Interstate transmission projects are bogged down by multi-jurisdictional approvals, making expansion slow and difficult.
  • "United States needs very significant growth in the cross country transmission infrastructure...so many jurisdictions and so many layers of approval that it's a very unwieldy kind of a project." (Philip Krein, 08:16)

7. Opportunity Amid Strain

• Despite the challenges, both guests see the data center demand spike as an opportunity:
  • If managed correctly, this pressure could drive overdue investment and grid modernization.
  • "Both Philip and Jay agree there's an opportunity to use this spike in power demand to build a better grid." (Waylon Wong, 08:54)

[Darian Woods]

Recently, Senator Bernie Sanders and Representative Alexandria Ocasio Cortez introduced a bill to pause new AI data center construction. Among their complaints electricity costs.

[Waylon Wong]

People's energy bills around the country are skyrocketing in order to pay for these AI data centers for them. Over the last five years, electricity prices have more than tripled in areas close to data centers. That's according to Bloomberg. These price rises have contributed to local opposition, blocking billions of dollars worth of data centers. And this week Maine's House passed initial approval on pausing most data center construction in the state. Both the Senate and Governor support the bill, so it's expected to pass.

[Darian Woods]

JJ Asseria is a utilities consultant and he says that data centers are a scapegoat for long standing issues in the electricity market.

[Jay Jayasira]

I think data centers are a factor, but to say that they're the ones solely responsible for higher electricity prices I think is perhaps misleading.

[Darian Woods]

So who's right? This is the indicator from Planet Money. I'm Darian Woods.

[Waylon Wong]

Welcome. And I'm Waylon Wong. Today on the show Data Centers and your Power Bill, we excavate years of underinvestment in the grid and ask whether the current wave of AI data centers could possibly even help.

Jay Jayasira is a consultant in Houston, Texas for Sendero Consulting. That's Where Jay works with electricity companies that power data centers. And Jay has a provocative thesis. He believes that AI data centers are unfairly getting the blame for more than a decade of underinvestment in the US grid. What's the state of America's electricity grids?

[Jay Jayasira]

They are functioning. You see a lot of the grid upgrading in certain ways. You know, there's new lines and transmission lines going up. There's the upgrade to be able to transport more power across the grid.

[Waylon Wong]

But Jay thinks that America's power grid has been underinvested in for 15 years, way before the AI boom. You've got power lines that can be vulnerable to storms and could spark wildfires, big renewable projects that can't connect to the grid as it is. Jay thinks that companies building AI data centers are by contrast actually trying to find new ways to get power.

[Jay Jayasira]

A lot of the data centers that are going up are, you know, responsibly finding ways to acquire power through, you know, these long term deals with providers or spending the money, investing the money to build a co located generator that will serve the data center needs.

[Darian Woods]

Right, they're putting natural gas plants on the data center site? Sometimes, yeah.

[Jay Jayasira]

I mean a natural gas plant, a combined cycle plant, you know, even looking at smaller nuclear options, Jay says that

[Darian Woods]

having the data center providing its own power on site could have spin off benefits for the rest of us. That's if the data center doesn't need all the power it's generating.

[Jay Jayasira]

Whatever access they have, they can provide into the grid.

[Waylon Wong]

Another way data centers could actually help. The grid is paying for fixed costs, maintaining power lines, clearing overgrown trees from those lines, building substations to convert electricity into the right voltages. These would be cost for the utilities, no matter how much power an individual house or business bought each day. And so when there's more electricity being generated and sold, those fixed costs as a share of your final power bill are lower. It's just like how a car company can bring down the price of cars by selling more of them. Economies of scale.

[Darian Woods]

In fact, earlier this year, the big power company in California, PG&E, said that data center growth had helped it cut electricity rates by 13% since 2024. And they cited the ways that data centers paid for more fixed costs as contributing to this.

[Waylon Wong]

But it's worth a reality check here. Philip Krein is a professor of electrical and computer engineering at the University of Illinois, Urbana Champaign. We asked Philip Krein what he thought of Jay Jayasuria's idea that data centers are the scapegoat for years of grid underinvestment.

[Philip Krein]

I don't accept that. I think that what's going on right now is data centers are walking in and say, hey, we want 20% more capacity than we want it today. That's just not a normal situation. Yeah.

[Darian Woods]

So Philip, it's the speed at which they want it that's causing strains. And in many places, higher electricity bills.

[Philip Krein]

Data centers and computing basically are sucking up 100% of potential future capacity and that is getting reflected back into the current rate base.

[Waylon Wong]

Phillips says it doesn't matter whether or not the grid had been properly investing over the last 15 years. He either way, the grid would struggle to meet this rapid increase in demand.

[Darian Woods]

Yeah, not everywhere is like California where power bills are going down. Like take Northern Virginia. Its electricity grid is already strained to its existing capacity. So a new data center needs new grid investments, new high voltage transmission lines, new substations, for example. That means higher bills.

[Waylon Wong]

That said, Philip believes it's possible that the US can increase its electricity generation and transmission by a lot. After all, it's already done this in the past.

[Philip Krein]

Between the late 1920s and the late 1970s, the US power grid grew by about a factor of 12. So the notion that we need to grow again by 20 or 30 or 50% is a little bit of a been there, done that kind of a thing.

[Darian Woods]

On the other hand, Phillips says the national grid kind of stopped growing in the 1980s. That's because appliances and factories got more energy efficient. So there wasn't much push for expanding capacity. Now we have growth in electric vehicles, air conditioning, home heating, converting to electric, and of course, AI data centers.

[Philip Krein]

Whether we can get back into that mode is the interesting question. But you know, we've done this before. We know how to do it.

[Waylon Wong]

Philip says growing the electricity sector is a matter of getting the right financial incentives, making sure it's economic for generators to build new capacity and send it to customers. One example electricity at the moment is regional. That means, say, New York in the evening can't buy cheap solar power from the Texas afternoon. What could solve this would be building huge transmission lines that could move electricity from state to state.

[Philip Krein]

The United States needs very significant growth in the cross country transmission infrastructure. I don't think anybody who knows the situation disagrees with that. But you know, a transmission line from Chicago to New York or California to Chicago goes through so many jurisdictions and so many layers of approval that it's a very unwieldy kind of a project.

[Darian Woods]

Yeah, I'll be honest. All that compliance and permitting sounds impossible, but Philip says it's not.

[Philip Krein]

We need to go back and see what we've done before, and some of it we need to do again.

[Waylon Wong]

Data centers in general are contributing to rising electricity bills. California is an example of one state that's an exception to this. But both Philip and Jay agree there's an opportunity to use this spike in power demand to build a better grid.
