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 utility payment obligations can make usable or saleable capacity differ from a site’s reserved power. The company says the examples are not based on a named customer site and has not disclosed independently verified results.
Rymvard published four illustrative US data center capacity scenarios on Oct. 3, showing how grid connection delays, emergency curtailment, cooling limits and utility tariffs can leave operators with less power to use or sell than a site’s stated reservation suggests. The examples cover Northern Virginia, Texas, Arizona and central Ohio; Rymvard says they use an illustrative estate, not a customer facility or reported outcome.
The company says its early-access product combines measured power, contracts, recovery reservations, cooling and demand in one ledger, a challenge also explored in analysis of AI data centers’ power bottleneck. Its examples frame capacity as more than a single contracted or reserved figure: operators may also need to account for when utility service arrives, how much a facility actually draws, which loads can be reduced, and what the cooling system can support.
In Northern Virginia, Rymvard points to delays that can stretch for years for new utility connections. It also describes existing reservations where measured draw is below the amount reserved, suggesting that capacity potentially available for sale this year may already be within a campus rather than dependent on a new connection. The company does not identify a specific campus or quantify that potential.
For Texas, Rymvard cites Senate Bill 6, signed in June 2025, and says sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. Its scenario concerns planning for critical services and loads that might be reduced; it does not report an actual curtailment event or describe a facility’s response.
The other examples focus on different limits. Rymvard says extreme heat can constrain cooling in Arizona. 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, even if actual use is lower. The cited tariff is the AEP Ohio data center tariff in case 24-508-EL-ATA, with an order dated July 9, 2025.

Why Reserved Power Can Mislead
The examples highlight a planning issue for data center operators: reserved capacity is not necessarily capacity that can be used, sold or afforded. A delayed connection can hold back expansion; curtailment requirements can affect which workloads remain online during grid stress; hot weather can make cooling the binding constraint; and a tariff can leave a site paying for subscribed power it does not draw.
Those differences can shape customer commitments, equipment deployment and cost forecasts. Utilities and grid planners may also benefit from a clearer distinction between power a facility has reserved and the load it actually draws, alongside information about loads that might be reduced. But the announcement does not establish that Rymvard’s ledger changes grid outcomes or improves planning in practice.
The company presents the product as a way to organize these factors, not as a source of additional power or a remedy for connection delays. Its examples help illustrate why headline capacity alone can be an incomplete planning measure, while leaving the size and frequency of the problem at individual sites unquantified.

Four Markets, Four Constraints
Rymvard’s scenarios are local examples, not a national capacity forecast. Northern Virginia’s case concerns utility connection timing and the gap between reservations and measured draw. Texas’s focuses on curtailment obligations; Arizona’s on cooling during the hottest afternoons; and Ohio’s on the cost attached to subscribed power under a regulated tariff.
The company says its product is in early access, and that the published screens and scenarios use an illustrative estate. No customer, site or result is identified. Rymvard has not published pricing, saying terms are agreed with early-access partners, and invites interested parties to contact the company. These limits matter when interpreting the announcement: it describes a product concept and the constraints it is designed to track, rather than a documented customer deployment.

Evidence Still to Be Shown
The announcement does not identify customers using the product or provide measured results, quantified savings, or evidence that the ledger has changed capacity planning or curtailment decisions. The four scenarios are illustrative; they are not accounts of specific campuses or forecasts for the four markets.
Rymvard has not detailed the product’s data inputs, integrations or verification methods, or how operators would use the ledger in operational decisions. It also has not shown how often these constraints occur across the named regions or what financial effects they have at individual sites. Pricing is not published, and the company has not announced a broader release schedule.

Customer Deployments and Verification
Rymvard says the product is available through early access, but has not named a customer or given a date for a wider release. The next developments to watch are whether it identifies deployments, explains how it verifies site-specific measurements and contracts, and reports outcomes that can be checked independently.
Until those details emerge, the scenarios are best read as examples of the capacity-planning problems Rymvard wants its ledger to organize. They do not yet show that the product shortens utility connection timelines, reduces costs or changes the amount of power a data center can reliably use.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios on Oct. 3, 2026, and described an early-access product that combines power measurements and operational or contractual information in one ledger.
Which markets do the scenarios cover?
The examples cover Northern Virginia, Texas, Arizona and central Ohio. Each focuses on a different constraint: connection delays, curtailment, cooling or tariff obligations.
Do the scenarios describe actual customer facilities?
No customer site or result is identified. Rymvard says the examples use an illustrative estate and should not be read as reports about a specific campus.
What has Rymvard shown about the product’s results?
The announcement does not provide independently verified outcomes, quantified savings or evidence that the product has changed capacity planning or grid operations. Rymvard says the product is in early access.
What information is still missing?
Rymvard has not named customers, published pricing or announced a broader release date. Details about data inputs, verification, integrations and measured product outcomes are also not provided.
