Rymvard published four illustrative data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. They show how grid connection delays, curtailment rules, cooling limits and tariff obligations can make a facility’s reserved power differ from what it can use, sell or afford. The examples do not document customer sites or demonstrate that Rymvard’s product has produced results.
Rymvard published four illustrative scenarios on Oct. 3, 2026, showing how grid connection delays, emergency curtailment, cooling limits and utility tariffs can affect the power available to US data centers, as explored in the original analysis. The examples cover Northern Virginia, Texas, Arizona and central Ohio, and frame a planning issue for operators: a site’s headline power reservation may not match the capacity it can reliably use, sell or afford.
In Northern Virginia, Rymvard points to long waits for new utility connections and to existing reservations where measured draw is below the amount customers reserved. The company says that, in such cases, capacity available to sell this year may already be within a campus rather than dependent on a new connection. The announcement does not provide measurements for a named site.
For Texas, Rymvard cites 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. Its scenario focuses on distinguishing equipment needed for critical services from loads that might be reduced; it does not report an actual curtailment event or a facility’s response.
In Arizona, Rymvard says cooling can limit capacity during the hottest afternoons. In central Ohio, it points to an AEP Ohio tariff approved by the Public Utilities Commission of Ohio that requires certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. The cited tariff is in commission case 24-508-EL-ATA, with an order dated July 9, 2025.

Why Reserved Power Can Mislead
The scenarios highlight that contracted or reserved power is not automatically usable capacity. A delayed grid connection can hold back expansion; curtailment obligations can shape which loads stay online during grid stress; hot weather can constrain cooling; and a tariff can leave a facility paying for power it does not draw. These factors can affect customer commitments, equipment plans and operating-cost forecasts.
For utilities and grid planners, separating actual demand from reserved capacity could help clarify how much power a campus draws and which loads may be flexible. Rymvard says its early-access product brings measured power, contracts, recovery reservations, cooling and demand into one ledger. That is the company’s proposed approach, not evidence that the product has increased available grid capacity or changed operating outcomes.
The distinction matters as data center operators plan around power access and cost, but the announcement offers no estimate of how widespread these constraints are or how much they affect individual sites. Its examples illustrate different local issues rather than a single national capacity forecast.

Four Markets, Four Constraints
Rymvard describes the scenarios as an illustrative estate, not a customer site or outcome. Each example addresses a different constraint: connection timing and the gap between reserved and measured demand in Northern Virginia; curtailment planning in Texas; cooling during extreme heat in Arizona; and payment obligations under an Ohio tariff. The company says the product is currently in early access.
The announcement does not name customers or provide independent validation, quantified savings, or evidence that the product has improved capacity planning, lowered costs or changed curtailment decisions. Rymvard has not published pricing, saying terms are agreed with early-access partners. Details about its data inputs, integrations, verification methods and role in operational decisions were not provided.

Evidence Still Missing
The four scenarios do not establish how often the described constraints occur across each market or the financial effect at any particular site. No customer deployment, site-specific measurements or product outcomes are identified. The examples should not be read as reports of real campus events or forecasts for all data centers in those regions.
It is also unclear how the ledger verifies measurements and contracts, connects to operators’ existing systems, or informs decisions during grid stress. The announcement supplies no published price list or broader release date. While Rymvard presents the ledger as a way to organize relevant information, it does not show that the product can shorten connection queues, remove cooling limits or change tariff obligations.

Customer Results to Watch
Rymvard says its product is available in early access and invites interested parties to contact the company. It has not announced a general release date, named customer deployments or disclosed a pricing schedule. The next evidence to watch for is whether it reports deployments or independently verifiable results and explains how its system handles site-specific measurements and contracts.
Until those details are available, the scenarios are best understood as demonstrations of the planning problems Rymvard aims to organize—not proof that its product has solved them. A ledger may make competing limits easier to track, but it cannot by itself create grid capacity or change the underlying rules and physical constraints.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative US data center power scenarios on Oct. 3, 2026, describing constraints in Northern Virginia, Texas, Arizona and central Ohio.
What can make a data center’s reserved power differ from usable capacity?
The examples point to grid connection delays, curtailment requirements, cooling limits and tariff obligations. The effects depend on local conditions and site-specific agreements.
Do the scenarios describe actual customer sites?
No. Rymvard says they use an illustrative estate; the announcement does not identify a customer or report a specific facility outcome.
What does the Ohio tariff require, according to the announcement?
Rymvard says the tariff applies to certain new data centers above 25 MW and requires payment for at least 85% of subscribed power for up to 12 years. It cites an order in Public Utilities Commission of Ohio case 24-508-EL-ATA, dated July 9, 2025.
Has Rymvard shown that its product improves power planning?
The announcement describes the product as being in early access, but provides no customer results, independent validation or quantified savings. Its effect on planning or grid outcomes remains unestablished.
