Open the resourceCAMPUS CHALLENGE / DECISION BRIEF
The next lease can sell the same power twice even when the meters show substantial unused capacity.
ILLUSTRATIVE FAILURE SCENARIO
Assume the presently supported campus capacity is 100 MW of total facility demand. Tenant A has rights to 60 MW but currently uses 30 MW. Tenant B requests a firm 50 MW allocation. Actual use makes the deal appear comfortable, but firm reservations would total 110 MW before any additional operating margin is considered. If A exercises its growth right before the next upgrade, the owner has promised more than the system can deliver. The missing 10 MW is a contractual conflict, not evidence of a future efficiency gain.
Hypothetical development case. Assumptions are not project results, quoted prices or predicted failure rates.
TEXAS / LAW, REGULATION & LOCAL REQUIREMENTS
Reviewed September 10, 2026
Development issues to resolve, not a legal opinion. Applicability depends on the parcel, provider, project configuration and current instruments. Texas counsel, the responsible authority and qualified technical specialists should confirm the route before commitments are made.
Use these questions to direct the review, not to determine legal eligibility. Open the applicable constraint below for the source, consequence and next action.
Texas basis. Section 37.0561 directs uniform requirements for when capacity subject to an outstanding financial commitment may be reallocated. It is not a private campus lease-allocation rule. Texas Utilities Code §37.0561
Campus consequence. An owner's proposed tenant swap can require both a supported provider position and changes to private reservations. A commercial release from one tenant does not by itself establish a new utility allocation.
Resolve before commitment. Reconcile the current provider rules and agreements with each tenant's reservation, release and growth rights. Record which approvals and payments are required before marketing the released capacity.
Texas basis. The notice describes provisional classifications and conditions, including verification and model-data issues, rather than an unconditional campus capacity award. ERCOT September 3, 2026 conditional-classification notice
Campus consequence. Calling conditional future service firm inventory can create two layers of overcommitment: one between the campus and grid process, another between the campus and tenants.
Resolve before commitment. Label each allocation by provider-supported date and unresolved conditions. Do not convert a conditional project classification into an unconditional tenant reservation without an owner-approved risk decision.
01 / CAMPUS EXPOSURE
COMBINED FAILURE TEST
Bring both growth rights forward to their earliest exercisable dates and move the shared upgrade later. Allocate on the contractual and physical envelope that remains. If the rights no longer fit, resolve the conflict before signing a third commitment.
02 / RESPONSE CHOICES
These are decision conditions, not universal thresholds. Confirm the evidence with the responsible providers, specialists and affected tenants before the owner authorizes a commitment.
Advance whenThe new tenant accepts an explicit upgrade condition and its commercial consequences before execution.
Stop or revise whenSales materials or side letters promise a firm date inconsistent with that condition.
Tie the additional capacity to a specified upgrade and avoid an unconditional tenant date. The tenant must accept the commercial consequence of the condition.
Advance whenThe affected tenant executes a supported release or revised ramp and the provider position permits the proposed use.
Stop or revise whenThe supposed release is inferred from low meter readings rather than an enforceable change.
Negotiate a genuine release, exchange or staged ramp with the affected tenant. Meter readings alone cannot extinguish a reservation.
Advance whenThe controlling bottleneck has a supported upgrade route, funding and date on the required service basis.
Stop or revise whenAdditional equipment leaves the upstream restriction unchanged or the date depends on unclosed conditions.
Advance the controlling upgrade only after land, provider, equipment and funding conditions support its date. More equipment behind the same upstream bottleneck does not close the gap.
Sitebraid would establish a dated capacity-rights register that reconciles tenant commitments to the engineer-supported system and provider position. We would identify double allocations, compare commercial rephasing with infrastructure investment and carry the selected changes into leases, procurement and the campus plan. The purpose is to make the next commitment supportable without appropriating another tenant's rights.
03 / DECISION GATE
NEXT ACTION
Subtract contractual rights, not current consumption, from supported capacity. Then ask where and when the remainder is deliverable before marketing it.
Reviewed September 10, 2026. The scenarios and decision tests are Sitebraid analysis. Source materials establish context, not approval of a particular project. Applicable law, provider terms and technical requirements require project-specific confirmation.
Project-specific study and commissioning requirements must be confirmed with the serving utility and ERCOT. An announced MW total is not a tenant allocation or an unconditional energization commitment.
