On November 10, 2026, the Tennessee Valley Authority signed its first disclosed deal under the data center tariff it adopted in August — and the number changes the conversation about who pays for the data center buildout. In its fiscal 2026 annual report, filed Friday, November 13, TVA said it entered into a Capacity Commitment Charge agreement with a data center customer entitling it to aggregate payments of $1.7 billion: $31 million due on signing, with the balance paid over 59 subsequent installments. TVA did not name the customer or the site.

The deal is the first real money attached to an up-front capacity charge for data centers, arriving barely six weeks after the tariff took effect on October 1. Until now, the charge was a rate design — a number in a board presentation, about $1.5 million per megawatt above five megawatts. Now it is a signed agreement with a payment schedule, and the who-pays question this desk has covered as a policy argument for months has become a contract.

The size of the deal also says something about the size of the load behind it, though TVA did not say it directly. The filing states that charges under the agreement are based on approximately $1.5 million per megawatt of requested capacity above five megawatts. Divide $1.7 billion by that rate and you get roughly 1,130 megawatts of chargeable capacity — about 1.1 gigawatts of requested load, the first five exempt megawatts aside. That is a calculation from the disclosed figures, not a TVA disclosure, and the “approximately” in the rate means the true figure could sit either side of it. But the order of magnitude is not in doubt: a gigawatt-scale commitment, the kind of single siting decision that now determines a region’s growth.

That scale is what makes the deal consequential beyond its dollar figure. TVA set a 2,000-megawatt cohort threshold for fiscal 2027, available first-come, first-served. A single agreement implying roughly 1.1 gigawatts would consume more than half of that first-year cohort. The cohort was designed as a rationing device, rewarding early movers; the first mover has taken most of the room, and TVA has said its cohort-based pricing methodology may be revised for future cohorts.

What the filing actually discloses

The disclosure is short, and its brevity is itself informative. TVA’s annual report says the agreement was entered into on November 10, 2026, that TVA is entitled to $1.7 billion in aggregate payments, that $31 million was due on signing, and that the rest comes in 59 installments. It does not name the customer, the site, the delivery point, or the energization date. It does not say whether the installments are equal or on what schedule — though spread evenly, each would be roughly $28 million.

The accounting treatment is also unresolved in a way worth noting. TVA plans to book the $31 million initial payment as a receivable with an offsetting regulatory liability, and it is still deciding over what period to amortize it. The money is committed, but how and when it flows through TVA’s books as revenue is a decision still to be made. TVA also expects the charge to give it an additional source of liquidity — a reminder that the charge is as much a financing instrument as a pricing signal.

The filing ties the charge to the rate package TVA’s board approved on August 20, 2026, at its quarterly meeting in Memphis: new data center rate schedules, effective October 1 and phased in through fiscal 2029, alongside the Capacity Commitment Charge for new and expanding data center loads above five megawatts, created “to cover the incremental capacity costs of data center demands.” TVA says the changes align with its Ratepayer Protection Pledge, the subject of a March 4, 2026, proclamation, and are meant to protect existing customers “from cost shifting and rising rates.”

A recap of the tariff, now with a customer

For readers who followed our October coverage, the mechanics will be familiar; what has changed is that they now have a customer. The board’s August package moved data center load out of the general industrial manufacturing rate class and into its own dedicated rate structure. TVA said average billing for data center customers would rise approximately 10 percent, phased in over three fiscal years. The centerpiece is the Capacity Commitment Rider: new or expanded data center load above the first five megawatts of contracted demand faces a charge of approximately $1.5 million per megawatt, an upfront commitment to fund the grid upgrades the new load requires. TVA CFO Tom Rice said the provision covers the incremental capacity cost the data center rate alone does not cover.

The rate applies broadly, including to bitcoin mining — which is why the small Mississippi mining site we covered in October moved onto the new tariff rather than remaining on the manufacturing rate. The charge bites only on the megawatts above the threshold, so a gigawatt-scale load pays on essentially all of it, while a facility at or below five megawatts escapes entirely.

The October story also showed the other side of the cutoff. PowerCompute signed a contract on September 30 raising its Columbus, Mississippi site from 8.5 to 11 megawatts — one day before the tariff took effect — and was assessed no charge, because the contracted load predated October 1. A brand-new 11-megawatt load would have faced roughly $9 million. The November 10 agreement is the mirror image: a customer that arrived after the cutoff, at roughly a hundred times the scale.

The year behind the deal

The agreement landed inside a strong fiscal year. For the year ended September 30, 2026, TVA reported total operating revenues of $14.22 billion, up 4.0 percent from $13.67 billion the year before, on electricity sales of 171.7 billion kilowatt-hours, up about 2.4 percent. Net income rose 56 percent to $2.12 billion, from $1.36 billion — $761 million higher, mainly on higher revenues and lower expenses. Operating income reached $3.29 billion, up 28 percent, and capital spending was $4.9 billion. Sales to local power companies — the distributors that resell TVA power to homes and businesses — rose 3.9 percent to $12.82 billion.

The data center story was already visible in TVA’s results: in the first nine months of the fiscal year, TVA said higher power sales were largely driven by the data processing, web hosting, and related services sector. A utility reporting $2.12 billion in net income does not need the $31 million signing payment to stay solvent; the charge is not a rescue. Its purpose is structural — to attach the cost of new capacity to the customer that triggers it, before the concrete is poured, rather than socializing it afterward.

What the deal proves — and what it does not

Start with what it proves. First, the tariff is no longer theoretical. A customer has accepted the charge at gigawatt scale, answering the question that hung over the August approval: would any developer actually sign under a $1.5 million-per-megawatt reservation price, or would the load go elsewhere? At least one has, at a scale that fills more than half the first-year cohort. Second, it proves the cohort mechanism works as a rationing device in the direction TVA intended — early movers claim the capacity, and the price of waiting is a smaller remaining pool and possibly a revised rate for later cohorts. Third, it proves the charge can generate money that matters against TVA’s buildout: $1.7 billion in committed payments is a meaningful contribution to a capital program running at nearly $5 billion a year.

What it does not prove is nearly as important, and the gaps are where the cost-shift question will actually be decided. A signed agreement is not a built data center. TVA has disclosed no energization date, no construction milestones, and no terms governing what happens if the customer delays, downsizes, or walks away. Until the load is energized and consuming power under the Large Data Service schedules, the $1.7 billion is a payment stream, not a served customer.

Nor does one deal prove the charge covers the full incremental cost. TVA describes the charge as covering the incremental capacity costs of data center demands, and CFO Tom Rice has said it covers what the data center rate alone does not. But “incremental capacity cost” is an estimate, made before the generation and transmission to serve this load are built, and the true cost will only be known when the assets are in service. If the build costs more than the cohort pricing assumed, the shortfall lands somewhere — and the filing gives no cost figure for serving this load against which to test the $1.7 billion.

There is also the question of who is on the other side of the signature. TVA did not name the customer or the site, and that anonymity is standard for a commercial agreement disclosed in a financial filing. But it means the public cannot yet judge the counterparty risk: whether this is a hyperscaler for whom 59 installments are a formality, or a developer whose ability to pay depends on financing not yet closed. The strength of the protection the charge offers depends on the strength of the party promising to pay.

The demand risk TVA still carries

The same annual report that discloses the deal is candid about the risk on the other side of it. TVA lists unexpected demand increases — driven by factors such as AI data centers, cryptocurrency mining, electric vehicles, and new large customer loads — alongside unexpectedly low demand as risks that “could result in stranded costs, rate actions, curtailments, or a need for unplanned capital.” If data center demand outruns its plans, TVA warns, it may have to buy power at higher prices, delay serving new industrial customers, or, in an emergency, curtail load. The charge prices one customer’s share of that risk; the system-level risk remains.

On the supply side, TVA is building. Three of the four generators at the Cumberland combined-cycle gas plant began pre-commercial operation in fiscal 2026, and the board approved another 1,550 megawatts of gas generation targeted for 2032. The Nuclear Regulatory Commission approved TVA’s construction permit for a GE Vernova Hitachi BWRX-300 small modular reactor at its Clinch River site in Oak Ridge, Tennessee, though TVA has not yet decided whether to construct a reactor there. The 2026 Integrated Resource Plan puts the Valley’s added generation need at 11 to 32 gigawatts by 2040, depending on how much of the prospective demand actually arrives.

A different mechanism from the FERC fight

It is worth distinguishing this deal from the other who-pays story in this week’s news. Elsewhere, the cost-shift argument is being made as a petition: a utility asking a regulator to change the rules so data centers fund the transmission their load requires. TVA’s charge is not a request. It is a tariff already in effect, adopted by the board of the nation’s largest public power supplier — and now with a signed, billion-dollar agreement under it. A petition can be denied or narrowed; a tariff in effect collects money while the argument continues.

That does not make TVA’s approach replicable everywhere. TVA is a federal power producer with a board that sets its own wholesale rates; most utilities answer to state commissions and, for interstate transmission, to FERC. The mechanism travels less easily than the logic — but the logic is now attached to a real transaction, and other utilities will be watching whether the customer builds and whether the installments arrive on schedule.

What to watch

Four things will determine whether this deal becomes a template or a footnote. The first is the cohort: with more than half of fiscal 2027’s 2,000 megawatts apparently claimed by one agreement, how quickly does the remainder fill, and does TVA revise pricing for the next round? The second is the customer: when TVA or the customer names the site, the counterparty risk question gets an answer. The third is the build: whether the generation and transmission funded by the charge arrive on the timeline the reservation implies, and at anything near the estimated cost. The fourth is the accounting: over what period TVA amortizes the $31 million, and how the 59 installments are recognized.

The bottom line

Six weeks after TVA’s data center tariff took effect, the Capacity Commitment Charge has its first customer, its first payment schedule, and its first billion-dollar number: $1.7 billion in aggregate payments, $31 million on signing, the rest over 59 installments, for what the arithmetic suggests is roughly 1.1 gigawatts of requested capacity. That is real money attached to a real principle — the customer causing the build pays for it — and it takes more than half of TVA’s first-year cohort in a single signature.

What it is not, yet, is proof that the principle holds. The customer is unnamed, the load is not yet built, the installments are not yet paid, and the cost of serving that load is not yet known. The deal proves developers will sign under the charge. Whether it proves households are protected is a question the next several years will answer.
