Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, focusing on Northern Virginia, Texas, Arizona and central Ohio. The examples describe how grid connections, curtailment rules, cooling limits and utility charges can make usable or sellable capacity differ from power a site has reserved; they are not customer results or a national forecast.
Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, describing how grid connection delays, emergency curtailment, cooling limits and utility charges can constrain the power a facility can use or sell. The examples cover Northern Virginia, Texas, Arizona and central Ohio, and are intended to show why reserved capacity may differ from operationally available capacity—not to report results from particular customer sites.
The examples address different constraints in each market. In Northern Virginia, Rymvard points to long waits for new utility connections and to existing reservations where measured electricity use is below the amount customers reserved. In that situation, the company says capacity that could be sold this year may already be on a campus rather than dependent on a new connection. It does not publish measurements for a named site.
In Texas, Rymvard discusses Senate Bill 6, signed in June 2025. As the company describes the law, data centers of 75 megawatts or more must accept curtailment when the grid operator sheds load. The scenario highlights the need to distinguish equipment supporting critical services from loads that could be reduced. It does not document a specific curtailment event or operator response.
For Arizona, the example says cooling can become the limiting factor on the hottest afternoons. In central Ohio, it cites a Public Utilities Commission of Ohio-approved tariff requiring certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. Rymvard says its early-access product brings measured power, contracts, recovery reservations, cooling and demand into a single ledger.

Why Reserved Power Can Mislead
A site’s power reservation is not necessarily the same as capacity it can reliably use, offer to customers or afford. A delayed connection can hold back expansion; a curtailment obligation can affect which workloads remain online during grid stress; heat can restrict cooling; and a tariff can leave a facility paying for power it does not draw.
Those distinctions can shape customer commitments, equipment plans and cost forecasts. For utilities and grid planners, better visibility into measured demand and loads that can be reduced could help distinguish contracted power from actual consumption. Rymvard presents its ledger as a way to organize these factors, but the announcement supplies no independent validation, quantified savings or evidence that the product changes grid outcomes. A record-keeping tool, by itself, does not add generation or speed up a utility connection.

Four Markets, Four Constraints
The scenarios are local examples, not a national capacity forecast. Northern Virginia’s example concerns connection timing and the difference between reserved and measured demand. Texas’s centers on a law and curtailment obligations for larger facilities. Arizona’s focuses on cooling in extreme heat, while Ohio’s concerns the cost of subscribed power under a regulated tariff.
The Ohio reference is the AEP Ohio data center tariff in Public Utilities Commission of Ohio case 24-508-EL-ATA, with an order dated July 9, 2025. Rymvard says the product is available in early access, but its published screens and scenarios use an illustrative estate. The company identifies no customer, campus or operational outcome.

Evidence Still to Come
The announcement does not name customers using the product or report measured results, cost savings or changes in capacity planning. It also does not explain in detail how the ledger verifies site measurements, connects to operational systems or informs decisions. The examples do not establish how frequently each constraint occurs across the markets or what its financial effect is at an individual facility.
Rymvard has not published prices, saying terms are agreed with early-access partners. Because the scenarios are illustrative, they should not be read as accounts of actual campuses, predictions for each market or proof that the product has improved grid outcomes.

Early Access and Validation
Rymvard says the product is in early access and invites interested parties to contact the company. It has not announced a broader release date, a public pricing schedule or a named customer deployment.
The next useful evidence would be customer deployments and independently verifiable results, along with details on how the system handles site-specific measurements and contracts. Until those are available, the four scenarios demonstrate the planning problems Rymvard aims to organize, rather than showing that its product has solved them.

Key Questions
What did Rymvard publish?
It published four illustrative data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio.
Are the scenarios based on named customer sites?
No. Rymvard says they use an illustrative estate and do not identify or imply a customer or specific campus.
What constraints do the examples describe?
They cover utility connection delays, curtailment obligations, cooling limits and tariff costs, each in a different regional example.
Has Rymvard shown that its product improves capacity planning?
The announcement provides no quantified results or independent validation. It describes the product’s intended function but does not establish its effects.
When will the product be broadly available?
Rymvard says it is in early access, but has not announced a broader release date or public pricing schedule.
