Headroom by Sinteag Energy

Capacity evidence.
Before you commit.

Check whether the supplied records support your planned load over the period that matters. Identify constraints and evidence gaps before committing to diligence, partners or contracts.

Headroom is read-only software that checks a proposed load against a site's power, battery, fuel and cooling records over the period that matters. When records are stale or conflict, it does not fill the gap. It withholds support and names the record that needs fixing.

No equipment access or control credentials needed.

From records to a finding

Power is only part of the answer.

Check the proposed load, the resources behind it and the cooling it needs.

Illustrative workflow. Not a verified engine result.

6.0 − 4.2 − 1.0 = 0.8 MW electrical margin.
This electrical balance alone does not establish site capacity.

Power

Proposed demand fits the stated limit.

Supported
Fuel

Required fuel exceeds the allowance after protected reserves.

Not supported
Cooling

Proposed heat load fits the stated cooling limit.

Supported

Overall: Not supported

Power and cooling fit. The proposed operating plan exceeds the usable fuel allowance.

Next engineering check: Review the generator schedule and protected fuel requirement. Supply an evidenced alternative for Headroom to reassess.

Electrical figures show simple arithmetic; fuel and cooling outcomes are illustrative. A site assessment requires a defined period, compatible method and supporting records.

Complete illustrative finding shown.

A connection rating is where the question starts.

A connection rating does not tell you what an additional load can use. Existing demand, protected reserves and cooling limits determine whether the proposal fits.

Existing demand

The load already on site, and the obligations it must keep serving, come off the top.

Reserves and duration

Battery energy, generator fuel and protected reserves decide how long a load can run, not just whether it starts.

Cooling

Power that fits can still fail on heat. Headroom reports power and cooling separately, and both must pass.

Synthetic example. Not a customer result.

Operator assessment / Changed demand records

The same expansion. A different finding.

The original electrical proposal was Supported. Higher existing-demand bounds leave a 190 electrical kW shortfall after the protected grid commitment during one of the six assessed hours. The full-period electrical finding becomes Not supported; thermal and combined findings were Not evaluated.

Original minimum margin
+580 electrical kW
Changed-record margin
−190 electrical kW

Review the changed demand evidence and protected commitment before relying on the expansion assumption. Results depend on the stated synthetic assumptions.

Inspect the finding and its basis

Screen the pipeline. Evaluate the survivors. Commit where the evidence holds.

  1. Screen. Run the same supported question across your candidate sites. See which constraint binds at each and which records are missing.
  2. Evaluate. Take the strongest sites into a full evaluation with engineer-confirmed records and a written finding.
  3. Commit. Move forward on the sites where the evidence supports the load, with the basis ready for partners and reviewers.

Built for the people who have to stand behind a capacity number.

See who uses Headroom

Which site questions fit?

Start with the equipment arrangement and the decision. These are separate supported methods, not permission to combine arbitrary assets.

Can the supplied gas-backed plan support the load?

One grid connection and one already-running natural-gas engine or turbine on a common electrical bus.

Uses documented manufacturer operating points and bounded gas supply. No battery combination, startup or islanding.

Natural-gas method scope

Do power, battery energy and diesel fuel cover the period?

One grid-connected site, one battery and one already-running No. 2-D diesel generator with an isolated fuel tank.

Checks supplied profiles and protected obligations. No refueling, extra units or dispatch optimization.

Grid/battery/diesel method scope

Does compatible cooling support the proposed heat load?

Bounded air, single-phase liquid or mixed cooling, with one documented shared heat-rejection stage.

A separate thermal finding accompanies a compatible power evaluation. It does not approve the whole proposal.

Cooling assessment scope

A finding with the reasoning attached.

An analyst prepares authorized CSV/JSON exports and supporting evidence. Headroom calculates the applicable balances and margins, checks limits and protected obligations, and generates a finding with source references. The site engineer confirms the mapped records and applicable conditions. Who provides that confirmation, and any additional engineering review needed, is agreed during scoping. Headroom does not provide external engineering approval.

  1. 01

    Agree the question

    Define the proposal, method, period and authorized use.

  2. 02

    Map the records

    The analyst preserves source references, units, timing and uncertainty.

  3. 03

    Confirm the basis

    The responsible engineer confirms the applicable limits and assumptions.

  4. 04

    Evaluate the case

    The software calculates separate power, resource and cooling findings and the overall result.

  5. 05

    Review next actions

    Trace constraints and gaps to the records or decisions that need attention.

You receive a written finding, relevant limits and margins, source references, evidence gaps and next engineering actions. Technical evidence and replay materials support review within the agreed assessment.

Test the assumptions.
Keep the observations.

Controlled what-if cases identify changed assumptions without rewriting original observations. Evaluate the operating periods you specify and compare compatible cases, with ties and reviewer judgment left visible.

Site reports, comparison records and portfolio summaries support later diligence. They do not determine the maximum available megawatts or discover arbitrary operating windows.

How comparisons and evidence review work

One site. One question. An agreed period.

First Site Evaluation

Start with a fit discussion by email. The paid assessment covers one site and one decision, with scope, quote, authorization and data handling agreed before records are shared.

Standard assessments: Written finding within five business days after scope is agreed and the required records are confirmed. Broader assessments, including coupled power-and-cooling work, follow the schedule agreed in the written quote.

Review the records checklist and who develops Headroom. No sensitive records are needed for the initial inquiry.

Read-only, export-based and analyst-assisted. Findings apply to a supplied proposal, defined period and supported method; they are not operating approval or guaranteed capacity. Public capacity examples are synthetic. Customer-site validation and qualified external engineering review remain outstanding. Method boundaries and verification
