Rymvard published four illustrative data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples show how grid access, curtailment, cooling and tariff obligations can make usable or sellable capacity differ from reserved power; they do not document customer sites or prove the company’s product improves outcomes.
Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, showing how grid connection delays, emergency curtailment, cooling limits and utility charges can leave operators with less capacity to use or sell than their power reservations suggest, as explored in the original analysis. The company says the examples cover Northern Virginia, Texas, Arizona and central Ohio and are based on an illustrative estate, not identified customer sites or results.
The scenarios examine distinct constraints in each market. In Northern Virginia, Rymvard points to potentially lengthy waits for new utility connections and describes reservations that exceed measured demand. It says capacity that could be sold this year may already exist within a campus, rather than depend on a new connection. The company does not provide site-level measurements or quantify the gap.
In Texas, the example concerns Senate Bill 6, signed in June 2025. Rymvard says sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. Its scenario is about identifying critical services and loads that could be reduced; it does not report an actual curtailment event or a facility’s response. In Arizona, the example focuses on cooling limits during the hottest afternoons.
For central Ohio, Rymvard cites an AEP Ohio tariff approved by the Public Utilities Commission of Ohio. Under the tariff described by the company, certain new data centers above 25 MW must pay for at least 85% of subscribed power for up to 12 years. Rymvard says its early-access product brings measurements, contracts, recovery reservations, cooling and demand into one ledger. Pricing is not published and is agreed with early-access partners.

Capacity Beyond the Power Reservation
A site’s contracted or reserved power is not necessarily the amount it can reliably use, offer to customers or afford. Connection delays can hold back expansion; curtailment obligations can shape which services remain online during grid stress; and heat can constrain cooling. A tariff may also require payment for subscribed power even when actual draw is lower.
These differences can affect customer commitments, equipment deployment and cost forecasts. For utilities and grid planners, separating reserved capacity from measured demand and flexible loads could clarify how much power facilities actually draw and what demand might be reduced. Rymvard’s examples make that planning issue visible, but they do not show that its ledger creates new grid capacity or changes grid outcomes.
The announcement supplies no independent validation, quantified savings or evidence of improved capacity planning. The product is a proposed way to organize relevant information; whether it leads to better decisions remains unestablished.

Four Markets, Four Constraints
Rymvard presents these cases as local examples, not a national capacity forecast. Their common thread is the difference between a headline power reservation and capacity available under site-specific operational, contractual and physical limits. The factors vary: utility service timing in Virginia, curtailment rules in Texas, cooling during extreme heat in Arizona, and payment obligations in Ohio.
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 its product is in early access. It has not named customers or identified a deployment site, and says the published screens and scenarios use an illustrative estate. That distinction matters: the examples describe the problem the company aims to organize, rather than measured outcomes at operating campuses.

Product Results Still Unreported
Rymvard has not identified customers or site deployments, disclosed measured results, or quantified savings or changes to capacity planning and curtailment decisions. The scenarios are illustrative and do not establish how often each constraint occurs across a market or the financial impact at a particular facility.
The company has not detailed the product’s data inputs, integrations, verification methods or how operators use its ledger in operational decisions. Its pricing is not public, and it has not announced a broader release date. The examples also do not demonstrate that the product can shorten utility connection waits, ease cooling limits or alter tariff obligations.

Evidence to Watch in Early Access
Rymvard says the product is available in early access and invites interested parties to contact contact@rymvard.com. The company has not announced a general release schedule or named customer deployments. Further reporting from Rymvard could clarify how site measurements and contracts are entered, checked and used.
The next meaningful evidence would be customer deployments or independently verifiable results showing whether the ledger changes capacity decisions, costs or curtailment planning. Until such information is available, the four scenarios are best read as demonstrations of planning challenges, not proof of product outcomes.

Key Questions
What did Rymvard announce?
It published four illustrative data center capacity scenarios for Northern Virginia, Texas, Arizona and central Ohio, alongside information about an early-access product that combines measurements, contracts and other constraints in a ledger.
Do the examples describe actual customer sites?
No. Rymvard says the scenarios use an illustrative estate. It has not identified customer sites or presented the examples as measured customer outcomes.
What constraints do the scenarios cover?
They cover utility connection delays in Northern Virginia, curtailment obligations in Texas, cooling limits in Arizona and power-payment requirements under an Ohio tariff.
Has Rymvard shown that its product improves capacity planning?
Not in the published material. The company has not disclosed independent validation, quantified savings or measured planning results.
What is known about availability and pricing?
Rymvard says the product is in early access. It has not published prices or announced a broader release date; pricing is agreed with early-access partners.
