NC Governor and Attorney General Ask Regulators to Make Duke Energy's Data-Center Cost Pledge Enforceable

A Promise Signed, and a Second Opinion Filed the Same Day

On July 23, 2026, the White House announced a bigger version of something called the Ratepayer Protection Pledge. It's a voluntary commitment: tech companies building data centers, not ordinary households, should pay for the huge amounts of power those centers use^[3][5]. Duke Energy, North Carolina's largest utility, signed on that day as one of the new participants^[3][5].

Hours later, North Carolina's governor and attorney general said that signature didn't settle anything. Gov. Josh Stein and Attorney General Jeff Jackson called on Duke and state regulators to turn the pledge into an enforceable rule, not just a promise^[1]. Jackson put it plainly: "A promise in Washington doesn't lower a power bill in North Carolina^[1]."

Nobody in this fight is arguing that families should cover the electric bill for a data center. That part isn't in dispute anywhere, from the White House to the state capitol^[1][3]. What's in dispute is whether a signed pledge actually stops it from happening, or whether only a binding state rule can^[1][11].

Why One Kind of Customer Can Reshape a Whole State's Grid

Data centers don't draw power the way a house does. They pull enormous, steady loads around the clock to run the computer servers behind artificial intelligence. Duke Energy says these large customers now account for more than 85% of all new electricity demand from projects seeking service in North Carolina^[9][8].

To keep up, Duke has proposed building about 9.7 gigawatts of new natural-gas power plants over the next decade^[9]. That's a huge amount of new equipment, and someone has to pay for it. Under the normal rules that govern regulated utilities, those costs get spread across every customer's bill, whether or not they personally use any of the new power. That practice is called cost socialization^[9][10].

Cost socialization exists for a reason. Duke is a regulated monopoly, so customers can't shop around for a cheaper power company. In exchange, regulators typically let Duke spread big infrastructure costs across its whole customer base and earn a set return on what it invests in new plants and lines. That arrangement works fine for shared upgrades, like a substation serving an entire region.

The problem is scale. A single data center can use as much electricity as a small city. If its costs get folded into rates the same way a routine grid upgrade would, ordinary households end up covering part of a bill for usage that looks nothing like their own^[9]. That's the exact mechanism Stein and Jackson want to shut off.

Two Fixes on the Table, and One Already in Motion

Stein and Jackson are asking for two specific things. First, a mandatory "large-load tariff": a legally binding rate structure that would make data centers cover the full cost of the power and infrastructure built to serve them^[1]. Second, a program letting data centers build or buy their own power generation directly, so they lean less on the shared grid^[1].

Duke has already taken a step toward the first idea. On July 17, 2026, Duke Energy Carolinas, the Utilities Commission's Public Staff, and other parties agreed to fast-track the process of designing a large-load tariff^[1]. Duke's own proposal would require big customers to pay a minimum bill for at least a decade, so the company isn't stuck covering the cost of a plant built for a customer that later leaves^[10].

How strict that tariff ends up is still unsettled. The Environmental Defense Fund has warned that without a firm, separate rate category, the cost of new plants "would be socialized across everyone who uses electricity^[9]." Latitude Media has described Duke's current proposal as a "light-touch" version that may not go far enough^[10]. There's also a federal wrinkle: some grid-upgrade costs fall under rules that can require broader cost-sharing no matter what a state decides, which limits how much any state promise can control on its own^[11].

Speed Versus a Signature Nobody Can Enforce

The White House and its allies frame the pledge as protection that's already working. Twenty-three Republican governors and roughly 187 signing utilities and companies are on board, and the administration says the pledge now reaches about 80% of the power delivered to U.S. homes and businesses^[3][5]. Their argument: if a tech company wants the power, it pays for the power, the delivery lines, and the grid upgrades, all without new mandates that could slow the AI buildout the administration wants to win globally^[3]. A broad voluntary deal can move faster than a state-by-state regulatory fight, and speed is central to that argument^[6].

Stein and Jackson, both Democrats, are making a different bet. A pledge carries no penalty if a signer breaks it^[6][12]. As elected officials watching bills climb, they also have a direct stake in being seen as the ones holding a powerful utility accountable. A binding tariff gives them something concrete to point to later. A voluntary federal promise gives them nothing to enforce^[1].

Duke sits between the two camps. It signed the federal pledge and agreed to fast-track the tariff process, but as a company that earns a return on the infrastructure it builds, it also wants rules loose enough to keep attracting data centers to its territory^[1][9][10]. Consumer and environmental groups are pushing the other way, for a tariff strict enough to protect bills and to limit the pollution that comes with 9.7 gigawatts of new gas plants^[9].

What the Coverage Reveals About Who's Convinced

How each outlet told this story tracked closely with how convinced it was that the pledge actually works. WRAL, a North Carolina outlet, stuck close to the mechanics: the officials' demands, Duke's fast-track agreement, no editorializing^[1]. The White House's own release was the most celebratory, pairing "American AI Dominance" with "Protects Consumers" and treating the voluntary pledge as a finished job^[3]. Fox News largely echoed that frame, describing a "massive coalition protecting Americans^[13]."

Outlets further from the administration leaned skeptical. The Washington Post put the word "voluntary" in its headline, flagging the enforcement question before the story even began^[7]. Canary Media, which covers clean energy, focused on the 9.7 gigawatts of new gas and called the proposed tariff "light-touch^[9]." Al Jazeera covered it from outside the U.S. political fight entirely, describing the pledge as an attempt to "blunt" public anger over bills rather than resolve the underlying cost question^[6].

A Consumer Reports survey suggests the doubt isn't confined to one side of the aisle. It found 75% of U.S. adults weren't confident that tech companies would truly cover all the electricity costs tied to their data centers, a doubt shared by majorities of both Democrats and Republicans surveyed^[3][14]. Whether that doubt gets answered now runs through a North Carolina Utilities Commission proceeding that's still writing its rules^[1][10].
