Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. They describe how grid connection timing, curtailment rules, cooling limits and utility charges can make usable or sellable capacity differ from a facility’s reserved power; the company has not disclosed independently verified product results.
Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, showing how grid connection delays, curtailment rules, cooling limits and utility charges can affect the power a facility can use or sell. The examples cover Northern Virginia, Texas, Arizona and central Ohio and are intended to show why reserved power does not always equal capacity available to serve customers.
The scenarios address different constraints rather than offering a single national capacity forecast. In Northern Virginia, Rymvard points to long waits for new utility connections and a possible gap between customer reservations and a campus’s measured draw. The company says capacity available to sell this year could already be within an existing campus, rather than depending on a new connection. It does not identify a specific site or quantify that capacity.
In Texas, the example concerns Senate Bill 6, which Rymvard says was signed in June 2025. Under the law as described by the company, sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. That creates a planning need to distinguish loads supporting critical services from those that could be reduced. The scenario does not report an actual curtailment or a facility’s response.
Rymvard says cooling can constrain output in Arizona on the hottest afternoons. In central Ohio, it points to a Public Utilities Commission of Ohio-approved tariff requiring certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. The cited order is dated July 9, 2025, in case 24-508-EL-ATA. Rymvard says its early-access product combines measured power, contracts, recovery reservations, cooling and demand in one ledger.

Why Reserved Power Can Mislead
A facility’s headline power reservation is not necessarily the amount it can reliably use, offer to customers or afford. Connection delays can hold up expansion; curtailment rules can affect which services continue during grid stress; heat can limit cooling; and tariff terms can leave operators paying for power they do not draw. These distinctions can affect customer commitments, equipment plans and cost forecasts.
For utilities and grid planners, better information about measured demand and loads that can be reduced may help distinguish reserved capacity from actual consumption. Rymvard presents its ledger as a way to organize those details, but the announcement does not establish that the product increases grid capacity or changes grid outcomes. It also provides no quantified savings or independently validated results.

Four Markets, Four Constraints
The examples treat capacity as a site-level operational question shaped by local conditions. Northern Virginia’s scenario focuses on the wait for utility service and the difference between reserved and measured demand. Texas centers on curtailment obligations; Arizona on cooling during extreme heat; and central Ohio on a regulated charge tied to subscribed power. The scenarios are illustrative, not reports of conditions at named campuses or projections for every data center in those regions.
Rymvard says the product is in early access and that its published screens and scenarios use an illustrative estate, not a customer site or outcome. The company has not named a customer deployment. Pricing is not published and is agreed with early-access partners, according to the announcement.

Product Results Remain Unverified
The announcement does not identify customers using the product or provide measured results showing whether it has improved capacity planning, reduced costs or changed curtailment decisions. It also does not quantify how often the cited constraints occur across each market or the financial effects at individual sites. The four examples should not be read as evidence about a particular facility.
Details about the product’s data inputs, integrations, verification methods and operational use are not provided. Rymvard has not announced a broader release date or a public pricing schedule. It remains unclear how the ledger handles site-specific measurements and contracts, or what independent evidence will be available to assess its performance.
Early Access and Evidence to Watch
Rymvard says the product is available in early access and invites interested parties to contact the company. It has not given a date for wider release. The next developments to watch are whether it names customer deployments, explains its data and verification methods, or publishes independently checkable outcomes from operational use.
Until those details emerge, the scenarios are best understood as demonstrations of the planning problems Rymvard aims to organize, rather than proof that its ledger solves them. A ledger may help operators view constraints together, but the announcement does not show that it can shorten utility connection waits, remove cooling limits or alter tariff obligations.
Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios covering Northern Virginia, Texas, Arizona and central Ohio. They show how local power and operating constraints may affect capacity available to use or sell.
What constraints do the scenarios describe?
They address utility connection delays in Northern Virginia, curtailment obligations for larger sites in Texas, cooling limits during extreme heat in Arizona, and a subscribed-power tariff for certain new data centers in central Ohio.
Are these examples from real customer sites?
No customer site or outcome is identified. Rymvard says the screens and scenarios use an illustrative estate, so they should not be treated as reports about a named campus.
Has Rymvard shown that its product improves planning or lowers costs?
The announcement provides no quantified savings or independently validated results. Rymvard has not identified customer deployments or reported evidence that the ledger changed planning or operational decisions.
What is known about availability and pricing?
Rymvard says the product is in early access. It has not announced a broader release date or public pricing; terms are agreed with early-access partners, according to the company.
