Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples describe how grid connection timing, curtailment obligations, cooling limits and utility charges can make usable or sellable capacity differ from a site’s power reservation; they do not document customer sites or prove the company’s product delivers results.
Rymvard published four illustrative U.S. data center power scenarios on Oct. 3, 2026, describing how grid delays in Northern Virginia, curtailment requirements in Texas, cooling limits in Arizona and a utility tariff in central Ohio can affect capacity operators can use or sell, as detailed in the original analysis. The company says the examples draw on an illustrative estate, not named customer sites or measured customer outcomes, and present the problem its early-access product is designed to organize.
The scenarios focus on a gap between a facility’s reserved or subscribed power and the amount it can draw, reliably use, sell to customers or afford—a challenge explored in the data center power bottleneck. Rymvard’s proposed ledger combines measured power, contracts, recovery reservations, cooling information and demand. The announcement does not provide independent validation of the product or quantify savings, improved planning or changes to grid outcomes.
In Northern Virginia, Rymvard points to long waits for new utility connections and says some existing reservations exceed measured draw, reflecting broader grid connection pressures. Its example suggests that capacity potentially available to sell this year could be within an existing campus, rather than dependent on a new connection. The company does not identify a particular campus or quantify the gap between reserved and measured power.
For Texas, the company cites Senate Bill 6, signed in June 2025. As Rymvard describes the law, sites of at least 75 megawatts must accept curtailment when the grid operator sheds load. Its example concerns planning which equipment supports critical services and which loads might be reduced; it does not report a specific curtailment event or facility response. In Arizona, the company says cooling can constrain capacity on the hottest afternoons. In central Ohio, it points to a tariff requiring certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years.

Why Reserved Power Can Mislead
The scenarios illustrate why a power reservation alone may not show how much capacity a data center can commit to customers or sustain in operation. Connection timing can limit expansion; a curtailment obligation may affect which services can continue during grid stress; heat can constrain cooling; and a tariff can leave an operator paying for power it does not use. These factors can influence customer commitments, equipment deployment and cost planning.
For utilities and grid planners, a clearer view of measured demand and flexible loads could help distinguish contracted capacity from actual consumption. But Rymvard’s announcement establishes neither that its ledger changes those decisions nor that it creates additional grid capacity. The examples explain a planning challenge and the product’s intended scope, not demonstrated results.

Four Markets, Four Different Limits
Rymvard presents the locations as separate illustrative cases, not a national forecast or a claim that every facility in each region faces the same constraint. The examples tie different issues to local conditions: utility service timing in Northern Virginia, state curtailment rules in Texas, hot-weather cooling in Arizona and a regulated power-charge structure in Ohio.
The Ohio example refers to 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 in early access and that its published screens and scenarios use an illustrative estate. The company has not named a customer deployment or published pricing; it says terms are agreed with early-access partners.

Customer Results Remain Unreported
The published scenarios do not identify customers, specific sites or measured outcomes. Rymvard has not quantified whether the product has improved capacity planning, reduced costs or altered curtailment decisions. Its announcement also does not establish how often the described constraints occur across the four markets or the financial effect they have at individual facilities.
Details about the product’s data inputs, integrations and verification methods, including how measurements and contracts are checked and used in operational decisions, are not provided. Pricing is not public, and the company has not announced a general release date. The scenarios should therefore be read as illustrations of issues the ledger aims to organize, not as evidence that it solves them.

Evidence to Watch in Early Access
Rymvard says interested parties can contact the company about early access; it has not announced a broader launch schedule. The next developments to watch are named customer deployments, details on how the product handles site-specific measurements and contracts, and independently verifiable results on planning or operating decisions.
Until such information is available, the four scenarios offer a framework for comparing reserved power with operational, contractual and cooling limits. Whether that framework helps operators make better commitments or lowers costs remains unconfirmed.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios for Northern Virginia, Texas, Arizona and central Ohio. They describe ways grid connections, curtailment, cooling and tariffs can affect usable or sellable capacity.
Are the scenarios based on real customer sites?
No customer site or outcome is identified. Rymvard says the examples use an illustrative estate and should not be treated as reports about particular campuses.
What is the company’s product intended to do?
Rymvard says its ledger brings together measured power, contracts, recovery reservations, cooling and demand. The announcement does not provide independent evidence that the product improves planning or produces savings.
What does the Ohio tariff example describe?
Rymvard cites an AEP Ohio tariff requiring certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. The company points to the tariff as an example of how payment obligations may differ from actual power use.
When will the product be broadly available?
Rymvard describes the product as being in early access but has not announced a general release date or public pricing schedule.
