Rymvard published four illustrative data center scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. They show how grid connection waits, curtailment rules, cooling limits and utility charges can make usable capacity differ from reserved power; the examples do not document customer sites or prove product results.
Rymvard published four illustrative US data center scenarios on Oct. 3, 2026, showing how grid connection delays, emergency curtailment, cooling limits and utility tariffs can leave operators with less capacity to use or sell than their headline power reservation suggests, as explored in the original analysis. The examples cover Northern Virginia, Texas, Arizona and central Ohio, but Rymvard says they are based on an illustrative estate, not identified customer sites or outcomes.
The scenarios describe different constraints rather than a single national capacity forecast. In Northern Virginia, Rymvard points to lengthy waits for new utility connections and a gap between reserved power and measured draw at existing sites. It says capacity available to sell this year may already exist within a campus, rather than depending entirely on new connections.
In Texas, the company discusses curtailment obligations under Senate Bill 6, signed in June 2025. As Rymvard describes the law, sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. That raises an operating-planning question: which loads support critical services and which could be reduced. The scenario does not report an actual curtailment event or a facility’s response.
Rymvard says Arizona heat can constrain cooling on the hottest afternoons. In central Ohio, it points to an approved tariff requiring certain new data centers above 25 megawatts to pay for at least 85% of subscribed power for up to 12 years. The company describes an early-access product that brings power measurements, contracts, recovery reservations, cooling and demand into one ledger. Pricing is not published and is agreed with early-access partners.

Why Reserved Power Can Mislead
A power reservation, a facility’s measured draw and the capacity it can reliably offer customers are not necessarily the same thing. Connection delays can push expansion further out; curtailment rules can affect operations during grid stress; heat-related cooling limits can constrain equipment; and a tariff can leave an operator paying for subscribed power it does not use.
Those differences can shape customer commitments, deployment plans and cost forecasts. Better records of actual demand and flexible loads may also help utilities and grid planners distinguish reserved capacity from electricity a site is drawing. Rymvard’s examples make that planning challenge concrete, but the announcement provides no independent validation, quantified savings or evidence that its product changes grid outcomes. A ledger can organize information; it cannot by itself create grid capacity, shorten a utility queue or remove a tariff obligation.

Four Markets, Four Constraints
Rymvard presents the cases as local operating examples, not a ranking of markets or a forecast of how often each constraint occurs. Northern Virginia’s example centers on connection timing and reserved versus measured demand; Texas’s on curtailment; Arizona’s on cooling in extreme heat; and Ohio’s on the cost of subscribed power.
For the Ohio example, Rymvard cites the AEP Ohio data center tariff in Public Utilities Commission of Ohio case 24-508-EL-ATA, with an order dated July 9, 2025. The company says its product is in early access. Its published screens and scenarios draw on an illustrative estate, and it identifies no customer, facility or measured result. The announcement also does not set out how widely these conditions apply across the four markets.

What the Examples Do Not Show
The scenarios do not establish how often the described constraints affect data centers in each region or how much they cost individual operators. No customer deployments, measured outcomes or quantified savings are identified. The examples should not be read as accounts of specific campuses or forecasts for local capacity.
Rymvard has not disclosed its pricing, named early-access partners or published details about data inputs, integrations, verification methods or how the ledger is used in operational decisions. It is also unclear whether the product has changed customer commitments, cost planning or curtailment decisions. Those gaps limit what can be concluded from the announcement beyond the planning problem it describes.

Evidence to Watch From Early Access
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, a published pricing schedule or a named customer deployment.
The next useful evidence would be disclosed deployments and outcomes that can be checked, along with more detail about how the ledger uses site-specific measurements and contracts. Until then, the four cases are best understood as illustrations of constraints the product aims to organize, not proof that it has improved capacity planning or changed grid conditions.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center scenarios on Oct. 3, 2026, describing how grid access, curtailment, cooling and tariff obligations can affect capacity in four US markets.
Are the scenarios based on named data centers?
No. Rymvard says the examples use an illustrative estate. The announcement does not identify customer sites or report specific facility outcomes.
What does the Ohio tariff example describe?
Rymvard says a tariff applies to certain new data centers above 25 megawatts, requiring payment for at least 85% of subscribed power for up to 12 years. The company cites the AEP Ohio tariff case before the Public Utilities Commission of Ohio.
Has Rymvard shown that its product reduces costs or improves capacity planning?
The announcement provides no quantified savings or independent validation and does not identify customer results. The product is described as being in early access.
