Rymvard published four illustrative U.S. data center scenarios on Oct. 3, 2026, focused on Northern Virginia, Texas, Arizona and central Ohio. The examples show how grid connection timing, curtailment rules, cooling limits and power tariffs can make usable or sellable capacity differ from a facility’s reserved power; they do not document customer sites or prove the company’s product improves outcomes.
Rymvard published four illustrative scenarios on Oct. 3 showing how different constraints in Northern Virginia, Texas, Arizona and central Ohio can limit the power data centers can use or sell, even when a site has reserved capacity, as explored in the original analysis. The company says its early-access ledger combines power measurements, contracts, recovery reservations, cooling and demand, but the examples use an illustrative estate rather than a customer site and provide no evidence of measured results.
The scenarios describe distinct constraints rather than a single national capacity forecast. In Northern Virginia, Rymvard points to lengthy waits for new utility connections and says some existing reservations exceed measured draw. That gap, the company argues, may mean capacity available to sell this year is already within a campus rather than dependent on a new connection, making rack deployment tracking relevant to capacity planning. The announcement gives no site-level measurements or examples identifying an operator.
In Texas, the company highlights Senate Bill 6, signed in June 2025. Rymvard says sites of 75 megawatts or more must accept curtailment when the grid operator sheds load. Its example frames this as an operational planning issue: operators need to identify which loads support critical services and which could be reduced. It does not report an actual curtailment event or describe how a particular facility responded.
For Arizona, the stated constraint is cooling on the hottest afternoons. In central Ohio, Rymvard points to an AEP Ohio tariff approved by the Public Utilities Commission of Ohio that requires certain new data centers above 25 megawatts to pay for at least 85% of subscribed power for up to 12 years. Rymvard says its ledger brings these conditions and commitments together, an approach that aligns with keeping data center AI accountable across teams. The company has not published prices; it says terms are agreed with early-access partners.

Why Reserved Power Can Mislead
A facility’s reserved or contracted power is not necessarily the amount it can reliably use, offer to customers or afford. A delayed grid connection can hold back expansion; curtailment obligations can affect which services continue during grid stress; high temperatures can limit cooling; and tariff rules can require payment for power a site does not draw. Those differences can shape customer commitments, equipment plans and cost forecasts.
For utilities and grid planners, separating measured demand from reserved capacity and flexible loads may help clarify how facilities interact with the grid. Rymvard presents its ledger as a way to organize those details, but the announcement does not show that the product creates new power, shortens connection waits or changes grid outcomes. The value of the examples is their illustration of different constraints, not proof of a solution.

Four Markets, Four Constraints
The scenarios address local conditions, not a claim that every data center in each state faces the same limits. Northern Virginia’s example concerns connection timing and the difference between reserved and measured demand; Texas’s concerns curtailment obligations; Arizona’s focuses on heat and cooling; and Ohio’s concerns the cost of subscribed power under a regulated tariff.
Rymvard identifies the Ohio reference as 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 example estate, with no customer or site identified or implied.

Evidence Behind the Examples
The announcement does not name customers or deployments, disclose measured results, or quantify any improvement in planning, costs or curtailment decisions. It also does not establish how frequently these constraints occur across the four markets or the financial effect at individual sites. The examples should not be treated as reports about specific campuses or forecasts for each region.
Rymvard has not detailed the product’s data inputs, integrations, verification methods or how operators use its output in live decisions. Pricing is unpublished and set with early-access partners. The available information also does not show that combining data in a ledger changes the underlying limits imposed by grid infrastructure, weather or utility rules.

Early Access and Proof Points
Rymvard says the product is available in early access and invites interested parties to contact contact@rymvard.com. The company has not announced a broader release date, public pricing schedule or named customer deployment. Further information about integrations and verification would help readers assess how the ledger works beyond the illustrative scenarios.
The next evidence to watch for is whether Rymvard reports customer use and independently verifiable outcomes, including how it handles site-specific measurements and contracts. Until then, the four examples show the problems the product aims to organize; they do not establish that it has improved capacity planning or grid operations.

Key Questions
What did Rymvard announce?
Rymvard published four illustrative U.S. data center capacity scenarios and described an early-access ledger intended to combine power measurements, contracts, recovery reservations, cooling and demand.
Which markets do the scenarios cover?
The examples focus on Northern Virginia, Texas, Arizona and central Ohio. Each addresses a different constraint: grid connection timing, curtailment, cooling or tariff obligations.
Do the examples describe actual customer facilities?
No. Rymvard says the scenarios use an illustrative example estate. The announcement identifies no customer site or facility outcome.
What remains unknown about the product?
Rymvard has not disclosed customer results, independent validation, public pricing or a broader release date. Details about data inputs, integrations and verification methods are also not provided.
