Rymvard published four illustrative U.S. data center capacity scenarios on Oct. 3, 2026, covering Northern Virginia, Texas, Arizona and central Ohio. The examples show how grid connection delays, curtailment rules, cooling limits and tariff obligations can make a site’s usable or sellable capacity differ from its power reservation; they do not establish customer results or prove the company’s product improves planning.
Rymvard published four illustrative scenarios on Oct. 3, 2026, showing how grid connection delays, curtailment rules, cooling constraints and utility tariffs can limit the power data centers can actually use or sell, as detailed in the original analysis. The examples span Northern Virginia, Texas, Arizona and central Ohio, and are intended to show why a facility’s reserved or subscribed power may not match its operational capacity. Rymvard says the scenarios use an illustrative estate, not a customer site or measured customer outcome.
In Northern Virginia, Rymvard highlights long waits for new utility connections and a potential gap between power customers have reserved and a campus’s measured draw. In the company’s example, capacity available for sale this year could be within an existing campus rather than dependent on a new connection. The material does not identify a specific facility or quantify the capacity involved.
For Texas, Rymvard points to Senate Bill 6, signed in June 2025. The company describes the law as requiring sites of 75 megawatts or more to accept curtailment when the grid operator sheds load. That makes it necessary for operators to distinguish critical-service equipment from loads that could be reduced. The example describes a planning consideration, not an actual curtailment event or a reported facility response.
In Arizona, the scenario focuses on cooling limits during the hottest afternoons. In central Ohio, Rymvard cites an AEP Ohio tariff approved by the Public Utilities Commission of Ohio. The tariff requires certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. Rymvard says its early-access product brings measurements, contracts, recovery reservations, cooling and demand into one ledger. It has not published pricing, which it says is agreed with early-access partners.

Reserved Power Versus Usable Capacity
The examples address a planning distinction with consequences for data center operators: power contracted or reserved is not automatically power available to serve customers. Connection delays can constrain expansion, curtailment obligations can affect operations during grid stress, and high temperatures can limit cooling. A tariff may also require payment for subscribed power even when a site draws less.
Those differences can shape customer commitments, equipment deployment and cost forecasts. Better visibility into measured demand and flexible loads could also help utilities and grid planners distinguish reserved capacity from actual consumption. But the announcement does not show that Rymvard’s ledger has changed grid outcomes, lowered costs or improved capacity planning. The examples frame the issue; they do not demonstrate a solution.

Four Markets, Different Constraints
The four scenarios are regional illustrations, not a national capacity forecast. Each focuses on a different constraint: connection timing and the gap between reservations and measured demand in Northern Virginia; curtailment obligations in Texas; cooling under extreme heat in Arizona; and the cost of subscribed power in Ohio.
For the Ohio example, Rymvard cites the AEP Ohio data center tariff in Public Utilities Commission of Ohio case 24-508-EL-ATA, with an order dated July 9, 2025. The company says its product is in early access. It describes the published screens and scenarios as based on an illustrative estate, and does not identify a customer, site or deployment.

Customer Evidence Still Missing
Rymvard has not named customers using the product, disclosed site measurements or quantified savings, planning improvements or changes to curtailment decisions. Its examples are illustrative rather than reports from specific campuses, so they do not establish how frequently the constraints occur across those markets or the financial effect at individual sites.
The company has also not detailed the product’s data inputs, integrations, verification methods or how its information is used in operational decisions. Pricing is unpublished, and the announcement gives no broader release date. As a result, the examples explain the problem Rymvard aims to organize, but do not establish that the product changes available grid capacity or produces measurable results.

Early Access and Evidence Ahead
Rymvard says interested parties can contact the company about early access; it has not announced a wider release schedule or named deployments. The next evidence to watch for is whether it reports customer use, explains how its ledger handles site-specific measurements and contracts, and provides outcomes that can be independently checked.
Until those details are available, the four scenarios are best read as examples of how local grid, operating and tariff conditions can separate headline power reservations from usable capacity—not as forecasts or proof of product impact.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative data center capacity scenarios covering Northern Virginia, Texas, Arizona and central Ohio. They describe how local grid and operating constraints can affect capacity a site can use or sell.
Do the scenarios describe actual customer sites?
No. Rymvard says the scenarios and product screens use an illustrative estate. The announcement names no customer site or measured outcome.
What is the Texas curtailment issue?
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 operational planning; it does not report a particular curtailment event.
What does the Ohio tariff require?
The tariff cited by Rymvard requires certain new data centers above 25 MW to pay for at least 85% of subscribed power for up to 12 years. The company references AEP Ohio’s tariff and a July 9, 2025 order in state case 24-508-EL-ATA.
Has Rymvard shown that its product improves capacity planning?
Not in the published material. Rymvard describes the product as in early access but provides no quantified results, named deployments or independent validation.
