Rymvard published four illustrative US data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples show how grid connections, curtailment rules, cooling limits and utility charges can make a site’s reserved power differ from what it can use or sell; they do not document customer sites or proven product results.
Rymvard published four illustrative data center capacity scenarios on Oct. 3, 2026, describing how grid connection delays, emergency curtailment, cooling limits and utility tariffs can constrain power available to use or sell in Northern Virginia, Texas, Arizona and central Ohio. The company says its early-access product brings measurements and commitments into one ledger, but the examples are based on an illustrative estate, not named customer sites or verified outcomes, as detailed in the original analysis.
The scenarios describe distinct local issues rather than a single national forecast, against a broader backdrop of grid constraints facing AI data centers. In Northern Virginia, Rymvard points to long waits for new utility connections and a gap between power customers have reserved and a campus’s measured draw. It says capacity that could be sold this year may already exist within a campus, rather than depending on new connections.
For Texas, Rymvard cites Senate Bill 6, signed in June 2025. As the company describes the law, sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. Its example raises an operational planning issue: operators need to distinguish equipment supporting critical services from loads that could be reduced. The announcement does not report a specific curtailment event or facility response.
In Arizona, the company says cooling can become the limiting factor on the hottest afternoons. In central Ohio, it points to an AEP Ohio tariff approved by the Public Utilities Commission of Ohio: certain new data centers above 25 megawatts must pay for at least 85% of subscribed power for up to 12 years. The referenced commission case is 24-508-EL-ATA, with an order dated July 9, 2025.
Rymvard says its ledger combines measured power, contracts, recovery reservations, cooling and demand. The company has not published pricing; it says terms are agreed with early-access partners. The announcement does not name customers or give quantified results for capacity planning, cost savings or grid operations.

Why Reserved Power Can Mislead
A site’s contracted or reserved power is not necessarily the amount it can reliably use, sell or afford. A delayed connection may constrain expansion; curtailment obligations may affect which loads can stay online during grid stress; hot weather can limit cooling; and a tariff can require payment for power a facility does not draw.
Those distinctions can shape customer commitments, equipment deployment and cost forecasts for operators. Better visibility into measured demand and flexible loads could also help utilities and planners distinguish a reservation from actual consumption. Rymvard’s examples frame that planning challenge, but the announcement does not show that its product changes grid outcomes or resolves those constraints.

Four Regions, Four Power Limits
The examples are intended to show why capacity can be affected by more than a site’s headline power figure. They pair local conditions with measured demand and contractual commitments: connection timing and reserved-versus-used power in Northern Virginia, curtailment obligations in Texas, cooling in Arizona, and subscribed-power costs in Ohio.
Rymvard describes the product as being in early access. Its published screens and scenarios use an illustrative example estate, and the company says no customer, site or outcome is identified or implied. The Ohio tariff reference is the AEP Ohio matter before the Public Utilities Commission of Ohio, case 24-508-EL-ATA; the order was dated July 9, 2025.

Product Results Remain Unreported
The four scenarios are illustrative, not reports about specific campuses. Rymvard does not identify customers using the product, quantify any improvement in planning or costs, or show that the ledger has changed curtailment decisions. It also does not explain in detail how the product verifies measurements, integrates with site systems, or handles site-specific contracts.
The announcement gives no estimate of how often the cited constraints occur across each market or how much they affect individual facilities. Pricing is unpublished, and the company has not announced a general-release date. The Texas example describes a legal requirement as Rymvard presents it; it is not evidence that a particular facility has been curtailed.
Evidence to Watch in Early Access
Rymvard says the product is available through an early-access program and invites interested parties to contact the company. It has not named a deployment, set out a pricing schedule or announced broader availability.
The next useful evidence would be named deployments or independently verifiable results, alongside more detail on data inputs, verification methods and how operators use the ledger in real decisions. Until then, the scenarios show the problems Rymvard aims to organize, not proof that the product improves capacity planning or creates additional power.
Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios covering Northern Virginia, Texas, Arizona and central Ohio. They describe ways that grid connections, curtailment, cooling and tariffs may constrain usable or sellable power.
Are the scenarios based on real customer sites?
No customer or site is identified. Rymvard says the examples use an illustrative estate and should not be read as customer results or market forecasts.
What is the product intended to track?
Rymvard says its ledger brings together measured power, contracts, recovery reservations, cooling and demand. The announcement does not provide independent evidence of the product’s impact.
What remains unknown about the product?
Rymvard has not named customers, published prices or quantified outcomes. Details about its data integrations, verification methods and operational use have also not been provided.
