Rymvard published four illustrative data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples describe how connection delays, curtailment rules, cooling limits and a utility tariff can separate reserved power from capacity a site can use or sell; they do not document customer results or prove the company’s product improves outcomes.
Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, describing how grid connection delays, curtailment requirements, cooling limits and utility tariffs can leave a facility with less capacity to use or sell than its headline power reservation suggests. The company says the examples cover Northern Virginia, Texas, Arizona and central Ohio and use an illustrative estate, not named customer sites or measured outcomes.
The examples focus on different local constraints rather than offering a national capacity forecast, as detailed in the original analysis. In Northern Virginia, Rymvard points to lengthy waits for new utility connections and a possible gap between power customers have reserved and a campus’s measured draw. It says capacity available to sell in the near term may already exist within a campus, rather than depend on a new connection.
For Texas, the company describes curtailment obligations under Senate Bill 6, which it says was signed in June 2025. Under the law as described by Rymvard, sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. The scenario raises the planning need to distinguish critical-service equipment from loads that could be reduced; it does not report a specific curtailment event or facility 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, requiring certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. The company says its early-access product brings measurements, contracts, recovery reservations, cooling and demand into one ledger.

How Local Limits Change Usable Power
A site’s reserved or contracted electricity is not necessarily the amount it can reliably use for computing, offer to customers or afford to pay for. Connection delays can limit expansion, while curtailment rules may affect which workloads continue during grid stress. High temperatures can constrain cooling, and a tariff can leave an operator paying for subscribed power even when actual draw is lower.
Those differences can shape decisions about customer commitments, equipment deployment and operating costs. For utilities and grid planners, a clearer account of measured demand versus reserved capacity could help distinguish what a facility draws from what it has contracted for. Rymvard presents its ledger as a way to organize those details, but its announcement provides no independent validation, quantified savings or evidence that the product changes grid outcomes.

Four Markets, Four Different Constraints
Rymvard’s scenarios are examples of how capacity can be affected by local conditions, not a claim that every data center in those regions faces the same limits. The Northern Virginia case concerns connection timing and reserved power versus measured demand; the Texas case concerns state curtailment rules; Arizona’s focuses on cooling in extreme heat; and the Ohio example concerns the cost of subscribed capacity under a regulated tariff.
The Ohio reference is 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 its product is in early access. It has not named customers or sites in the announcement, and says the published screens and scenarios are based on an illustrative estate.

Product Results Remain Undocumented
The announcement does not identify customers using the product, provide measured results or quantify whether the ledger has improved planning, lowered costs or changed curtailment decisions. The scenarios are illustrative and should not be treated as accounts of specific campuses or forecasts for the four markets.
Rymvard has not published pricing, instead saying terms are agreed with early-access partners. It also has not detailed the product’s data inputs, integrations or verification methods, or explained how those inputs inform operational decisions. The frequency of the constraints and their financial effects at individual sites are not established by the examples.

Customer Evidence and Broader Release
Rymvard says interested parties can contact the company about its early-access product, but it has not announced a broader release date, pricing schedule or named customer deployment. Further evidence to watch for includes customer deployments, an explanation of how the ledger uses site-specific measurements and contracts, and independently verifiable results.
Until the company provides that information, the four scenarios are best understood as examples of the planning problems its product aims to organize—not proof that it has improved capacity availability, reduced costs or changed grid operations.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios covering Northern Virginia, Texas, Arizona and central Ohio. It says its early-access product combines power measurements, contracts, recovery reservations, cooling and demand in one ledger.
Do the scenarios describe real customer sites?
No customer or site is identified. Rymvard says the examples use an illustrative estate, not a customer site or outcome.
What does the Texas example say about curtailment?
Rymvard says Texas Senate Bill 6, signed in June 2025, requires sites of 75 MW or more to accept curtailment when the grid operator sheds load. The example discusses planning for reducible and critical loads; it does not report an actual curtailment event.
Has Rymvard shown that its product improves capacity planning?
The announcement provides no quantified results or independent validation showing improved planning, lower costs or changed grid outcomes. The scenarios describe the problems the product aims to organize.
Is the product generally available, and what does it cost?
Rymvard says the product is in early access. It has not announced a broader release date or published prices, saying terms are agreed with early-access partners.
