  • House’s 100 MW Rewrite Would Make Data Centers a Separate Class of AI-Era Power User

    House’s 100 MW Rewrite Would Make Data Centers a Separate Class of AI-Era Power User

    TL;DR · 30-second read

    The Short Version

    Who should pay when a giant computer warehouse needs new power plants and power lines: the company, or its neighbors through their monthly electric bills?

    A United States House committee is working on a bill that says the company should pay. Lawmakers just rewrote it to target data centers, the buildings that run AI and online services, rather than every huge electricity user.

    There is a catch. States would only have to consider the rule, not adopt it. Google and Microsoft have supported the bill, but singling out data centers could bring lawsuits.

    E&E News reported that the House Energy and Commerce Committee has narrowed the Ratepayer Protection Act, H.R. 9340, so that it applies specifically to data centers. Committee leaders released the change as a substitute amendment, meaning replacement bill text, ahead of a markup (the committee session where legislation is debated and amended) that began Monday, July 20, and was set to continue Tuesday, July 21.

    The bill, sponsored by Reps. Gabe Evans (R-Colo.) and Kathy Castor (D-Fla.), would require states to consider adopting a federal standard directing data centers to pay the full cost of new generation and transmission upgrades needed to serve them. The earlier language could have applied to projects with peak electricity demand of 100 megawatts or more.

    Executive Summary

    The rewrite changes who the Ratepayer Protection Act is about. A bill that could have reached large projects based on their electricity demand would now be aimed at one type of facility: the data center. That sharpens the political message, but it also opens a question the earlier version largely avoided: why should one kind of large power user be treated differently from another?

    The core cost principle remains in the committee’s description of the bill: data centers should pay the full cost of the new generation and transmission upgrades needed to serve them. The enforcement mechanism is softer than that principle sounds, because states would be required to consider the standard, not to adopt it.

    The result matters to developers, utilities, state regulators and electricity customers. Support from both parties gives the bill momentum, yet the calendar, Democratic calls for stronger measures, an uncertain Senate path and possible legal challenges all stand between the committee’s text and any change in what customers pay.

    From a Size Test to a Single Industry

    The most consequential edit is a change in how the bill identifies its target. A 100-megawatt test turns on how much power a project demands at its peak; a megawatt is a million watts, and peak demand is the most a facility draws at one time. A data center test turns on what the facility is. Under the narrowed text, a large electricity user outside the data center category would appear to fall beyond the federal standard, even if it places a similar demand on the grid. That is the sense in which the rewrite would make data centers a separate class of power user.

    This goes to the heart of the industry’s position. Data center and technology companies have maintained that they should be treated similarly to other large power users, and the new language moves away from that principle. Their argument has an intuitive engineering logic: a transmission upgrade costs what it costs, regardless of what the customer does with the electricity. The case for the narrower approach is more political and more immediate. Data centers are the facilities generating nationwide concern, and committee leaders chose to address them directly.

    Each position leaves something to prove. Supporters of the narrower text need a principled reason for applying a cost rule to one class of large user and not another, particularly since the change could become fodder for lawsuits. The industry, for its part, needs to show that equal treatment would protect other customers at least as well, rather than simply diluting attention on the sector driving the current debate. Developers, utilities and other large users all have a stake in where that line lands.

    A Federal Standard That States Only Have to Consider

    The phrase “pay the full cost” is strong, but the operative verb is “consider.” As described, H.R. 9340 would require states to weigh adopting the federal standard, not necessarily to put it into effect. That leaves the practical decision at the state level, so protection for ratepayers, and costs for developers, could differ from one state to the next.

    For site selection teams and utility planners, that points to a patchwork risk. Passage of the bill would not by itself settle what a project pays. Teams would still need to follow how each relevant state responds, and a state’s decision could affect the economics of a project that requires new generation or grid upgrades.

    The hardest technical question sits inside the words “needed to serve them.” New power plants and transmission lines often serve many customers over many years, so deciding which portion of a shared upgrade belongs to one data center is an allocation exercise as much as a billing one. A standard’s value to ratepayers will depend heavily on how that line is drawn.

    Bipartisan Support, With Different Definitions of Enough

    Lawmakers from both parties appeared ready to back the legislation on Monday, but they did not describe it in the same way. Chair Brett Guthrie (R-Ky.) framed it as a way to pursue “the race to AI dominance” while helping ensure communities do not pay the associated electricity costs. Ranking member Frank Pallone (D-N.J.), who has endorsed a national moratorium on data center construction, called the bills “a good start” but said they “don’t go far enough,” adding that “we may need a moratorium” if Congress does not put sufficient guardrails in place.

    Reps. Doris Matsui (D-Calif.) and Paul Tonko (D-N.Y.) also advocated stronger legislation, and Democrats said they would push other bills on data center pollution and water concerns. Those are the issues this bill does not settle, and their separate treatment suggests that the cost standard may be only one front in a broader debate. The critics’ claim that the bill falls short has support in its consider-only design, though how much it would shift costs in practice remains untested.

    Timing is the other constraint. Guthrie had hoped for a floor vote before the August recess, which now looks like a long shot with the House set to leave at the end of the week. In the Senate, Sen. Jon Husted (R-Ohio) introduced a companion bill, S. 5028, and said he would keep working with the Energy and Natural Resources Committee. Its chair, Sen. Mike Lee (R-Utah), said last month of data center legislation, “I don’t currently have that identified as a priority.” Committee momentum is real, but it is not yet a path to enactment.

    Background

    Data centers are facilities filled with computing equipment that power AI and other online services. Their electricity needs have become a national political issue, with lawmakers debating how to support AI development while protecting other customers from higher bills. The House Energy and Commerce Committee, which is handling H.R. 9340, has pushed hard for the bill in recent weeks.

    US electricity oversight is divided between levels of government. States generally oversee retail electricity rates, while the Federal Energy Regulatory Commission oversees interstate transmission and wholesale power markets. That division helps explain why a federal standard that states must consider differs from a nationwide rule that directly sets what a data center pays.

  • Georgia’s 10 GW Data Center Build Shows the Next Who-Pays Fight Is Over Fuel

    Georgia’s 10 GW Data Center Build Shows the Next Who-Pays Fight Is Over Fuel

    TL;DR · 30-second read

    The Short Version

    Georgia’s utility regulators are investigating whether giant data centers, the warehouse-sized computer buildings behind artificial intelligence tools, pay their fair share of the cost of fuel for power plants.

    The state has already approved new power plants with nearly five times the output of its two newest nuclear reactors, mostly to serve data centers. Consumer groups say ordinary households may be paying to get fuel to those plants, even though they are only being expanded because of data centers.

    Hearings start in September. The answer could show up on Georgia power bills.

    WABE reported on July 8, 2026, that the Georgia Public Service Commission has opened an investigation into how Georgia Power’s largest customers, including data centers, pay for the fuel that runs the utility’s power plants. The probe examines the Real-Time Pricing (RTP) methodology used to bill those customers for fuel. Its first round of hearings is scheduled for September.

    The investigation grew out of this year’s fuel-rate proceedings for residential and small-business customers. Those proceedings ended in an agreement that lowered the fuel rate and called for a review of RTP. The probe covers Georgia Power only, not the state’s other utilities. Advocacy groups, including Georgia Conservation Voters Education Fund, welcomed the move.

    Executive Summary

    Georgia’s utility regulator has formally opened a question it had so far left aside in its data center policy: who pays for fuel. The commission has already approved about ten gigawatts of new generating capacity, mostly for forecast data center demand. It has also approved contract terms meant to make large customers pay for infrastructure built to serve them. The new investigation turns to operating costs, and specifically to the cost of getting fuel to newly expanded power plants.

    The mechanism at issue is billing. Residential and small-business customers pay a fuel rate. Data centers and other large users pay for fuel under Real-Time Pricing. Consumer advocates argue that this split leaves other Georgians carrying costs that exist only because of data center growth. The commission will now test that argument in hearings beginning in September.

    The outcome matters beyond one tariff. Georgia is one of the country’s fastest-growing markets for hyperscale data center load. How it allocates fuel costs will affect the long-run energy price data center developers face there, and the bills of the households and small businesses that share the same grid.

    Georgia Already Priced the Plants. Fuel Is the Open Line.

    The commission’s recent data center decisions have focused on capacity: the power plants and grid equipment needed to meet future demand. Late in 2025 it approved about ten gigawatts of new capacity to serve the higher demand Georgia Power is predicting, mostly from data centers. A gigawatt is roughly the output of a large power plant, and the approved total is nearly five times the capacity of the new nuclear reactors at Plant Vogtle. Earlier in 2025 the commission approved contract terms to help ensure that data centers and other large customers pay for infrastructure built to serve them. Georgia Power has also said it will cover costs if the predicted data center demand does not materialize.

    Those measures address who pays to build. The new investigation addresses who pays to run the plants, and in particular the cost of delivering fuel to newly expanded ones. Critics raised that cost during this year’s fuel hearings as the one slipping through the cracks, and it now has a formal proceeding of its own. This is the sense in which the next who-pays fight is over fuel. The capital side of the ten-gigawatt build already has a cost-allocation framework, however contested. The fuel side is where the allocation rules are now being reopened.

    The shift changes what each party has to argue about. Capacity disputes turn on demand forecasts and contract terms signed before a facility is energized. Fuel disputes turn on tariff design and cost accounting that play out over the years a plant runs. For a developer planning load in Georgia, the connection terms were the headline risk. The lifetime price of energy is now also under review. For households, fuel charges are generally passed through to customers at cost, so any shift in allocation reaches monthly bills directly. That direct link is why the issue surfaced in the residential fuel-rate case.

    How Real-Time Pricing Can Split the Fuel Bill

    Georgia Power’s residential and small-business customers pay for fuel through a fuel rate set in periodic proceedings before the commission. Large customers such as data centers pay for fuel under Real-Time Pricing. In general, real-time pricing tariffs charge a price that tracks the utility’s cost of producing electricity hour by hour, instead of a flat, averaged fuel charge.

    Consumer advocates argue that this arrangement leaves other Georgians paying for fuel infrastructure that is being built only because of data center demand. Their reasoning runs as follows. Getting fuel to an expanded plant carries costs of its own, and those costs can be committed in advance whether or not the fuel is burned in a given hour. Suppose those costs land in the averaged fuel rate, while the largest new users pay for fuel under a methodology that does not carry them the same way. Then the customers on the averaged rate absorb them. Whether Georgia’s RTP methodology actually works this way is what the investigation is meant to establish.

    The stakes grow with the buildout. The larger the share of new demand billed through RTP, the more its treatment of fuel-delivery costs matters to everyone else on the system. With roughly ten gigawatts approved largely on the strength of data center forecasts, the question stops being a narrow tariff detail. It becomes a material cost-allocation issue.

    What Each Side Still Has to Show

    The advocates’ concern is coherent on its mechanics. The September hearings are where it needs a figure: how much fuel-delivery cost is attributable to data center-driven expansion, and how much of that RTP customers already cover. As Ja’Mae Rooks of Georgia Conservation Voters Education Fund put it, “Georgians deserve to understand exactly who is paying for the massive growth in electricity demand from data centers, and who isn’t.” That standard applies in both directions. Establishing who is not paying requires the same cost data as establishing who is.

    The burden also falls on the utility and its large customers. If RTP already recovers these costs, the hearings are the place to show it with numbers. Georgia Power’s pledge to cover costs if data center demand fails to materialize addresses a different risk: infrastructure left underused. On its face, that pledge says nothing about ongoing fuel costs when the demand does arrive.

    The political setting raises the proceeding’s profile. Commission seats are on the 2026 ballot, and recent races have been framed around power bill increases. The result, though, will turn on the cost record the parties put before the commission, not on the campaign.

    A Test Case Worth Watching, Not Yet a Trend

    Georgia’s sequence gives other regulators a view of where cost questions surface after the first round of protections is in place. The order was capacity approvals, then contract protections for infrastructure, then a review of fuel methodology. Operating-cost allocation is harder to fix in a contract signed before a data center goes live, because it depends on how plants run and what fuel costs over many years.

    This is still one utility in one state, and the investigation has reached no finding. It is too early to say that fuel allocation will become a standard battleground wherever hyperscale load is growing. What Georgia does establish is that a utility can put infrastructure cost protections in place and still leave operating-cost allocation open for review.

    Background

    Georgia Power, a subsidiary of Southern Company, is Georgia’s largest electric utility. It is regulated by the Georgia Public Service Commission, whose elected commissioners set the rates the utility charges. In recent years the utility completed two new nuclear reactors at Plant Vogtle, and it has since forecast large demand growth driven mostly by data centers, including hyperscale facilities used for generative AI.

    To meet that forecast, the commission approved about ten gigawatts of new capacity in late 2025. Earlier that year it approved contract terms intended to make large customers pay for infrastructure built to serve them. Power costs have become a political issue in the state, with commission elections in 2026 framed around recent bill increases.
