12-Month Contract-Demand Headroom Planner
Review recorded maximum demand, identify the peak month and test a planned demand addition against your entered contract demand.
Step 2

How the calculation works
Utilization = recorded maximum demand ÷ contract demand. Headroom = contract demand minus recorded demand. The post-expansion scenario adds the full planned demand to every month; it does not assume diversity.
Cost-rule boundary
No universal tariff is built in. Cost appears only from entered rules and required provenance. It is not a bill forecast, legal interpretation or billing advice.
Decision boundary
The planner does not recommend reducing contract demand or changing supply. Billing definitions, ratchets, power factor, taxes, seasonal rules and utility approvals may materially change the result.
