The capacity problem often appears during leasing, not engineering. A new tenant asks for an earlier start, the leasing model shows unused megawatts, and the existing tenant has not yet exercised its expansion rights. Each statement can be accurate while the proposed deal is impossible to deliver. The owner needs to understand which capacity can actually be promised, at what date, and against which payment obligation.
The campus problem
Illustrative scenario, not a claimed client result.
A campus has an operating first tenant, a second tenant negotiating an accelerated opening and an uncommitted third phase. The master plan shows sufficient ultimate power, but the second tenant’s ramp moves ahead of a shared upgrade. Meanwhile, the first tenant has rights to grow. The conflict is not visible in any one building budget. The assignment is to find the feasible allocation and infrastructure sequence before a new commitment makes the mismatch harder to unwind.
Why apparently spare capacity is not always available
Consider an illustrative campus with 100 MW of supported facility demand in its first service stage. Tenant A has rights to 60 MW, even though it initially draws 35 MW. Tenant B requests 50 MW. Subtracting current consumption suggests ample headroom. Subtracting contractual rights shows a 10 MW shortfall. The example assumes comparable demand definitions and a supported operating envelope; it does not count backup equipment or an unapproved future upgrade as additional service.
The missing connection is between the electrical capacity record and the lease. A reservation can be conditional, time-limited, paid or unpaid. It may include a release mechanism, or it may survive years of low utilization. Those terms determine whether the sponsor can reuse capacity without breaching an existing commitment. A utilization forecast alone cannot settle the question. The lender also needs to know whether the payment supporting the infrastructure begins when capacity is reserved or only when the tenant starts operating.
The Texas context
ERCOT’s Large Load Integration materials include project-information and load-commissioning requirements. They provide a power-planning context, not a commercial allocation of capacity between campus tenants. Our proposed owner-side method connects the relevant provider-supported capacity envelope to tenant and phase commitments.
Underwrite the reservation, not the tenant logo
For each tenant, connect capacity rights to payment start dates, minimum commitments, cancellation conditions and available credit support. Have the owner’s financing and legal advisors establish whether the actual signing entity and guarantees support shared-asset repayment. Test a late tenant and a reservation that is never exercised. A technical capacity ledger should not be mistaken for a financeable revenue ledger.
Make the next offer conditional on a deliverable route
For the example above, the negotiating choices are concrete. Tenant B could open at a lower facility demand and expand after an accepted upgrade. Tenant A could agree to release a defined portion of its reservation for compensation. The sponsor could fund earlier shared works if the service provider and engineers establish that they can be delivered in time. Each route changes a different contract, so a generic capacity approval is not enough.
Sitebraid's role is to put those routes in one decision package, with the affected tenants, the required works, payment start dates and the party carrying the shortfall. If the upgrade slips, the package should show what B may operate, which payments continue and whether the owner can stop further spending. Once a route is approved, we coordinate the resulting service, design and commercial actions rather than leave the capacity spreadsheet disconnected from negotiations.
Solutions and their tradeoffs
Stage the new tenant’s ramp
A smaller opening commitment can be useful without consuming capacity needed by an existing tenant.
Conditions to resolve: Operator acceptance, provider-supported sequencing and appropriate changes to commercial commitments.
Advance or change the shared infrastructure
Additional works can support the commitments without unacceptable timing or cost exposure.
Conditions to resolve: Qualified design review, deliverable equipment and approvals, funding and a plan for effects on occupied phases.
Revise the commitment rather than oversubscribe it
No supported physical or commercial route delivers the requested promise.
Conditions to resolve: Owner approval of a revised date, scope or tenant arrangement before it is treated as deliverable.
The 100 MW campus has only 40 MW left to offer
Hypothetical facility-demand ledger matching the example above. The 100 MW is usable service after the relevant technical constraints, not nameplate generation or IT load. No additional reserve is assumed available to sell.

| Ledger entry | Facility demand | Commercial consequence |
|---|---|---|
| Supported service stage | 100 MW | The ceiling for simultaneous obligations in this example. |
| Tenant A reservation | 60 MW; initial use 35 MW | The unused 25 MW is not released merely because it is idle. |
| Uncommitted remainder | 100 - 60 = 40 MW | B's 50 MW request exceeds available rights by 10 MW. |
| A releases 10 MW by agreement | A 50 MW + B 50 MW = 100 MW | Possible only after amending the reservation and verifying the operating envelope. |
| No release or accepted upgrade | B opens at no more than 40 MW | Change B's commitment or hold the offer; do not sell the same 10 MW twice. |
This is the development problem behind our capacity allocation challenge. Our Power & energization capability explains the scope Sitebraid can take on.
Putting the analysis to work
We would review the owner’s tenant requirements with its commercial team and counsel, including opening dates, growth rights and conditions attached to reservations. The electrical team would establish the supported total-facility demand by phase, the relevant operating envelope and the limits of the current and planned system. We would connect that to provider records, equipment commitments and the shared-infrastructure budget. IT MW, total facility demand and nameplate equipment capacity must not be mixed in the same allocation calculation.
How Sitebraid would support this decision
Create a campus capacity-and-commitments record
For each phase, identify the tenant requirement, physical boundary, relevant units, earliest supported service position, commercial reservation and the infrastructure on which it depends. Give every entry an evidence source and update owner. Mark uncommitted future capacity as an option, not an achieved supply.
Test the collision before signing or spending
Run the proposed tenant change through the combined record with the operator, technical and commercial teams. Test delayed infrastructure, a faster tenant ramp and exercise of existing growth rights. Treat these as defined scenarios, not invented probabilities or assurances that demand will conveniently occur at different times.
Make the shared-asset decision explicit
Compare what must be built now with what can be deferred. Identify the party funding capacity reserved for future phases and the implications if those phases do not proceed. Have counsel and commercial advisors establish the relevant allocation and recovery arrangements; Sitebraid does not substitute an informal spreadsheet for tenant rights.
Put the selected plan into action
Align the accepted commitments with design releases, provider submissions and infrastructure packages. Record decisions about the timing and capacity each tenant receives. Update the campus basis after each acceptance so future negotiations begin with the current position rather than an obsolete development presentation.
How we protect the decision
A change in tenant date or load should trigger a campus review before a binding promise or major release. The owner decides which commercial tradeoff to accept and how much uncommitted expansion to fund. We would expose the dependencies and advance the approved route. We would not treat redundancy, emergency equipment or theoretical utilization diversity as freely saleable capacity without the responsible engineers and operators establishing the basis.
The result the owner should require
For a strategy engagement, the result is a reconciled, owner-approved capacity and commitments plan with the required changes and funding decisions identified. For a subsequent execution scope, the result includes closure of the specified provider, approval or shared-infrastructure dependencies. Neither outcome is simply a larger headline number. The meaningful test is whether the agreed tenant and phase commitments can be supported by the evidence at that stage.
How to measure progress
- Committed demand by phase and date against supported service and system capacity.
- Tenant reservations dependent on infrastructure not yet funded or delivered.
- Shared-asset cost exposure assigned to an owner-approved funding decision.
- Changes reviewed across the campus before new commitments are executed.
The decision to take forward
Reserve capacity against a documented service stage and a specific tenant obligation. Keep speculative expansion visible, but separate from capacity the leasing team may commit. The useful outcome is a supportable offer to the next tenant, with a funded path for anything the first stage cannot supply.
If several tenants are counting on the same spare capacity, our Power & energization work sets who holds it and by what date.
