Rymvard published four illustrative data center power scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples show how connection delays, curtailment rules, heat-related cooling limits and utility charges can separate a site’s reserved power from what it can use, sell or afford; they are not customer results or a national forecast.
Rymvard published four illustrative scenarios on Oct. 3 showing how power constraints in Northern Virginia, Texas, Arizona and central Ohio can limit the data center capacity operators can use or sell, even when a site has reserved power, as described in the original analysis. The company says the examples are based on an illustrative estate, not a customer site or measured outcome, and describe an early-access product intended to bring power measurements, contracts, cooling limits and demand into one record.
The cases focus on different constraints rather than a single estimate of U.S. data center capacity, a challenge also explored in analysis of the AI data center power bottleneck. In Northern Virginia, Rymvard points to long waits for new utility connections and to existing reservations where measured power use is below the amount reserved. It says some capacity an operator might sell this year could be within an existing campus, rather than dependent on new connections. The company does not provide site-level measurements or quantify the available capacity.
In Texas, the example concerns curtailment obligations under Senate Bill 6, which Rymvard says was signed in June 2025. The company describes the law as requiring sites of at least 75 megawatts to accept curtailment when the grid operator sheds load. Its scenario is an operational planning example, not a report of a specific grid event or facility response. In Arizona, Rymvard says cooling may constrain capacity on the hottest afternoons.
The central Ohio example concerns an AEP Ohio tariff. Rymvard says the tariff requires certain new data centers above 25 megawatts to pay for at least 85% of subscribed power for up to 12 years. The company identifies the related Public Utilities Commission of Ohio case as 24-508-EL-ATA, with an order dated July 9, 2025. The scenarios do not establish how frequently these constraints affect sites or their individual financial impact.

Why Reserved Power Can Mislead
The examples highlight a distinction operators, customers and planners may need to track: a facility’s headline power reservation is not necessarily the same as the capacity it can reliably use, sell or afford. A slow grid connection can delay expansion; a curtailment requirement can affect which loads continue during grid stress; hot weather can limit cooling; and a tariff can create costs even when a site draws less than its subscribed amount.
Those differences can shape customer commitments, equipment deployment and cost forecasts. A record that brings measurements and contractual obligations together could help an operator identify where capacity is constrained. But Rymvard’s announcement offers no independent validation, quantified savings or evidence that its product changes grid outcomes. Organizing information may support planning; it does not itself add grid supply, shorten connection queues or remove contractual obligations.

Four Markets, Four Constraints
Rymvard presents the locations as examples of distinct local issues, not as a national capacity forecast. Northern Virginia’s case is about utility service timing and the difference between reserved and measured demand. Texas’s concerns curtailment obligations, Arizona’s concerns cooling during extreme heat, and Ohio’s concerns the cost of subscribed power under a regulated tariff.
The company says its early-access product combines measured power, contracts, recovery reservations, cooling and demand in one ledger. It has not named customers using the product, published a price schedule or disclosed product results. Pricing is agreed with early-access partners, according to Rymvard. The published scenarios therefore illustrate the problems the product aims to organize, not demonstrated results for individual facilities.
“Rymvard joins measured power, contracts, recovery reservations, cooling and demand into one ledger.”

What the Examples Do Not Show
The announcement does not identify a customer, site or operational outcome behind the scenarios. It gives no quantified savings or capacity gains and does not show whether the product has changed planning, costs or curtailment decisions. The company also does not detail its data inputs, integrations or verification methods, or explain how the ledger is used in operational decisions.
It remains unclear how common each constraint is across the four markets, how large its financial effect may be at any particular site, and how much capacity could be made available by better tracking. The examples should not be treated as forecasts for those regions or as evidence that every site faces the same conditions. Rymvard’s account of the product and scenarios is company-provided information.
Early Access and Evidence Ahead
Rymvard says the product is available in early access and invites interested parties to contact the company. It has not announced a broader release date, public pricing schedule or named deployment. The next evidence to watch for is whether it identifies customer deployments, explains its measurement and verification methods, or reports outcomes that can be checked independently.
Until those details are available, the four cases show the types of constraints Rymvard wants operators to consider together; they do not establish that the ledger resolves them. The company’s announcement leaves open whether future disclosures will quantify effects on capacity planning, costs or grid operations.
Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center power scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. It says the cases are not based on a named customer site or customer outcome.
What constraints do the scenarios describe?
They cover utility connection delays and gaps between reserved and measured demand, Texas curtailment obligations, heat-related cooling limits in Arizona, and an Ohio tariff that can require payment for a share of subscribed power.
Does the announcement show that Rymvard’s product works?
No. The announcement describes an early-access product but does not identify customer deployments, publish measured results or provide independent validation. It does not quantify savings or capacity gains.
What does the Ohio tariff example say?
Rymvard says certain new data centers above 25 megawatts must pay for at least 85% of subscribed power for up to 12 years under the referenced AEP Ohio tariff. The company cites Ohio regulator case 24-508-EL-ATA and an order dated July 9, 2025.
