Regular energy consumers, not corporations, will bear the brunt of the increased costs of a boom in artificial intelligence that has contributed to a growth in data centers and a surge in power usage, recent research suggests.

Between 2024 and 2025, data center power usage accounted for $9 billion, or 174%, of increased power costs, a June report by Monitoring Analytics, an external market monitor for PJM Interconnection, found. PJM manages the electrical power grid and wholesale electric market for 13 states and Washington, D.C., and this spring, customers were told to expect roughly a $25 increase on their monthly electric bill starting June 1.

“The growth in data center load and the expected future growth in data center load are unique and unprecedented and uncertain and require a different approach than simply asserting that it is just supply and demand,” Monitoring Analytics’ report said.

Data centers house the physical infrastructure to power most of the computing we do today, but many AI models and the large AI companies that power them, like Amazon, Meta and Microsoft use vastly more energy than other kinds of computing. Training a single chatbot like ChatGPT uses about the same amount of energy as 100 homes over the course of a year, an AI founder told States Newsroom earlier this year.

The growth of data centers — and how much power they use — came on fast. A 2024 report by the Joint Legislative Audit and Review Commission in Virginia — known as a global hub for data centers — found that PJM forecasts it will use double the amount of average monthly energy in 2033 as it did in 2023. Without new data centers, energy use would only grow 15% by 2040, the report said.

As of July, the United States is home to more than 3,800 data centers, up from more than 3,600 in April. A majority of data centers are connected to the same electrical grids that power residential homes, commercial buildings and other structures.

“There are locational price differences, but data centers added anywhere in PJM have an effect on prices everywhere in PJM,” Joseph Bowring, president of Monitoring Analytics said.

Creeping costs

At least 36 states, both conservative and liberal, offer tax incentives to companies planning on building data centers in their states. But the increased costs that customers are experiencing have made some wonder if the projects are the economic wins they were touted as.

“I’m not convinced that boosting data centers, from a state policy perspective, is actually worth it,” said New Jersey State Sen. Andrew Zwicker, a Democrat and co-sponsor of a bill to separate data centers from regular power supply. “It doesn’t pay for a lot of permanent jobs.”

Energy cost has historically followed a socialized model, based on the idea that everyone benefits from reliable electricity, said Ari Peskoe, the director of the Electricity Law Initiative at the Harvard Law School Environmental and Energy Law Program. Although some of the pricing model is based on your actual use, some costs like new power generation, transmission and infrastructure projects are spread across all customers.

Data centers’ rapid growth is “breaking” this tradition behind utility rates.

“These are cities, these data centers, in terms of how much electricity they use,” Peskoe said. “And it happens to be that these are the world’s wealthiest corporations behind these data centers, and it’s not clear how much local communities actually benefit from these data centers. Is there any justification for forcing everyone to pay for their energy use?”

This spring in Virginia, Dominion Energy filed a request with the State Corporation Commission to increase the rates it charges by an additional $10.50 on the monthly bill of an average resident and another $10.92 per month to pay for higher fuel costs, the Virginia Mercury reported.

Dominion, and another local supplier, recently filed a proposal to separate data centers into their own rate class to protect other customers, but the additional charges demonstrate the price increases that current contracts could pass on to customers.

In June, the Federal Energy Regulatory Commission convened a technical conference to assess the adequacy of PJM’s resources and those of other major power suppliers, like Midcontinent Independent System Operator, Inc., ISO New England Inc., New York Independent System Operator, Inc., California Independent System Operator Corporation (CAISO) and Southwest Power Pool (SPP).

The current supply of power by PJM is not adequate to meet the current and future demand from large data center loads, Monitoring Analytics asserts in a report following the conference.

“Customers are already bearing billions of dollars in higher costs as a direct result of existing and forecast data center load,” the report said.

Proposed changes

One of the often-proposed solutions to soften the increased cost of data centers is to require them to bring their own generation, meaning they’d contract with a developer to build a power plant that would be big enough to meet their own demand. Though there are other options, like co-location, which means putting some of the electrical demand on an outside source, total separation is the foremost solution Bowring presents in his reports.

“Data centers are unique in terms of their growth and impact on the grid, unique in the history of the grid, and therefore, we think that’s why we think data centers should be treated as a separate class,” Bowring said.

Some data centers are already voluntarily doing this. Constellation Energy, the owner of Three Mile Island nuclear plant in central Pennsylvania, struck a $16 billion deal with Microsoft to power the tech giant’s AI energy demand needs. 

But in some states, legislators are seeking to find a more binding solution.

New Jersey Sen. Bob Smith, a Democrat who chairs the Environment and Energy Committee, authored a bill this spring that would require new AI data centers in the state to supply their power from new, clean energy sources, if other states in the region enact similar measures.

“Seeing the large multinational trillion dollar companies, like Microsoft and Meta, be willing to do things like restart Three Mile Island is crazy, but shows you their desperation,” said co-sponsor Zwicker. “And so, okay, you want to come to New Jersey? Great, but you’re not going to put the basis (of the extra cost) on ratepayers.”

New Jersey House members launched a probe into PJM’s practices as the state buys its annual utilities from the supplier at auction this month. Its July 2024 auction saw electrical costs increase by more than 800%, which contributed to the skyrocketing bills that took effect June 1.

Residents are feeling it, Smith said, and he and his co-sponsors plan to use the summer to talk to the other states within PJM’s regional transmission organization (RTO).

“Everything we’re detecting so far is they’re just as angry — the other 13 entities in PJM — as us,” Smith told States Newsroom.

Smith said they’re discussing the possibility of joining or forming a different RTO.

“We’re in the shock and horror stage where these new prices are being included in these bills, and citizens are screaming in pain,” Smith said. “A solution that I filed in the bill, is the one that says, ‘AI data centers, you’re welcome in New Jersey, but bring your own clean electricity with them so they don’t impact the ratepayers.”

Utah enacted a law this year that allows “large load” customers like data centers to craft separate contracts with utilities, and a bill in Oregon, which would create a separate customer class for data centers, called the POWER Act, passed through both chambers last month.

If passed, New Jersey’s law would join others across the country in redefining the relationship between data centers powering AI and utilities providers.

“We have to take action, and I think we have to be pretty thoughtful about this, and look at the big picture as well,” Zwicker said. ”I’m not anti-data center, I’m pro-technology, but I’m just not willing to put it on the backs of ratepayers.”

A moratorium on state-based artificial intelligence laws was struck from the “Big Beautiful Bill” Monday night in a 99-1 vote in the U.S. Senate, after getting less and less popular with state and federal lawmakers, state officials and advocacy groups since it was introduced in May.

The moratorium had evolved in the seven weeks since it was introduced into the megabill. At an early May Senate Commerce Committee session, Sen. Ted Cruz of Texas said it was in his plans to create “a regulatory sandbox for AI” that would prevent state overregulation and promote the United States’ AI industry.

GOP senators initially proposed a 10-year ban on all state laws relating to artificial intelligence, saying the federal government should be the only legislative body to regulate the technology. Over several hearings, congressional members and expert witnesses debated the level of involvement the federal government should take in regulating AI. They discussed state’s rights, safety concerns for the technology and how other governmental bodies, like the European Union, are regulating AI.

Over the weekend, Sen. Marsha Blackburn of Tennessee and Cruz developed a pared down version of the moratorium that proposed a five-year ban, and made exceptions for some laws with specific aims such as protecting children or limiting deepfake technologies. Changes over the weekend also tied state’s ability to collect federal funding to expand broadband access to their willingness to nullify their existing AI laws.

Monday night, an amendment to remove the moratorium from the budget bill — cosponsored by Blackburn and Sen. Maria Cantwell, a Washington Democrat — was passed 99-1.

“The Senate came together tonight to say that we can’t just run over good state consumer protection laws,” Cantwell said in a statement. “States can fight robocalls, deepfakes and provide safe autonomous vehicle laws. This also allows us to work together nationally to provide a new federal framework on Artificial Intelligence that accelerates U.S. leadership in AI while still protecting consumers.” 

The “overwhelming” vote reflects how unpopular unregulated AI is among voters and legislators in both parties, said Alexandra Reeve Givens, president and CEO of the tech policy organization, Center for Democracy and Technology, in a statement.

“Americans deserve sensible guardrails as AI develops, and if Congress isn’t prepared to step up to the plate, it shouldn’t prevent states from addressing the challenge,” Reeve Givens said. “We hope that after such a resounding rebuke, Congressional leaders understand that it’s time for them to start treating AI harms with the seriousness they deserve.”

Editor’s Note: This story has been updated to reflect the fact that Tennessee Sen. Marsha Blackburn backed off her own proposal late on Monday.

Senate Republicans are aiming to soften a proposed 10-year moratorium on state-level artificial intelligence laws that has received pushback from congressmembers on both sides of the aisle.

Sen. Marsha Blackburn of Tennessee and Sen. Ted Cruz of Texas developed a pared down version of the moratorium Sunday that shortens the time of the ban, and makes exceptions for some laws with specific aims such as protecting children or limiting deepfake technologies.

The ban is part of the quickly evolving megabill that Republicans are aiming to pass by July 4.  The Senate parliamentarian ruled Friday that a narrower version of the moratorium could remain, but the proposed changes enact a pause — banning states from regulating AI if they want access to the $500 million in AI infrastructure and broadband funding included in the bill.

The compromise amendment brings the state-level AI ban to five years instead of 10, and carves out room for specific laws that address rules on child online safety and protecting against unauthorized generative images of a person’s likeliness, often called deepfakes. The drafted amendment, obtained and published by Politico Sunday, still bans laws that aim to regulate AI models and decisionmaking systems.

Blackburn has been vocal against the rigidity of the original 10-year moratorium, and recently reintroduced a bill called the Kids Online Safety Act, alongside Connecticut Democrat Sen. Richard Blumenthal, Senate Majority Leader John Thune of South Dakota and Senate Minority Leader Chuck Schumer of New York. The bill would require tech companies to take steps to prevent potentially harmful material, like posts about eating disorders and instances of online bullying, from impacting children.

Blackburn said in a statement Sunday that she was “pleased” that Cruz agreed to update the provisions to exclude laws that “protect kids, creators, and other vulnerable individuals from the unintended consequences of AI.” This proposed version of the amendment would allow her state’s ELVIS Act, which prohibits people from using AI to mimic a person’s voice in the music industry without their permission, to continue to be enforced.

Late Monday, however, Blackburn backed off her own amendment, saying the language was “unacceptable” because it did not go as far as the Kids Online Safety Act in allowing states to protect children from potential harms of AI. Her move left the fate of the compromise measure in doubt as the Senate continued to debate the large tax bill to which it was attached.

Though introduced by Senate Republicans, the AI moratorium was losing favor of GOP congressmembers and state officials.

Senators Josh Hawley of Missouri, Jerry Moran of Kansas and Ron Johnson of Wisconsin were expected to vote against the moratorium, and Georgia Rep. Marjorie Taylor Greene said during a congressional hearing in June that she had changed her mind, after initially voting for the amendment.

“I support AI in many different faculties,” she said during the June 5 House Oversight Committee hearing. “However, I think that at this time, as our generation is very much responsible, not only here in Congress, but leaders in tech industry and leaders in states and all around the world have an incredible responsibility of the future and development regulation and laws of AI.”

On Friday, a group of 17 Republican governors wrote in a letter to Thune and Speaker Mike Johnson, asking them to remove the ban from the megabill.

“While the legislation overall is very strong, there is one small portion of it that threatens to undo all the work states have done to protect our citizens from the misuse of artificial intelligence,” the governors wrote. “We are writing to encourage congressional leadership to strip this provision from the bill before it goes to President Trump’s desk for his signature.”

Alexandra Reeve Givens, President and CEO of tech policy organization Center for Democracy and Technology said in a statement Monday that all versions of the AI moratorium would hurt state’s abilities to protect people from “potentially devastating AI harms.”

“Despite the multiple revisions of this policy, it’s clear that its drafters are not considering the moratorium’s full implications,” Reeve Givens said. “Congress should abandon this attempt to stifle the efforts of state and local officials who are grappling with the implications of this rapidly developing technology, and should stop abdicating its own responsibility to protect the American people from the real harms that these systems have been shown to cause.”

The updated language proposed by Blackburn and Cruz isn’t expected to be a standalone amendment to the reconciliation bill, Politico reported, rather part of a broader amendment of changes as the Senate continues their “vote-a-rama” on the bill this week.
