What you are paying for, and what you can use
Contracted demand is a standing cost and a hard ceiling at the same time. Setting it from connected load rather than from measurement means paying for capacity you never draw, or discovering a constraint after committing to an expansion.
What We Deliver
Demand from measurement, not summation
Real demand is established from metering across a full operating cycle. Connected load assumes everything runs at once, which never happens, and that assumption is where most over-contracting begins.
WHY IT MATTERS
Upgrading the most visible asset
A site with low voltage complaints and a transformer at sixty percent loading does not need a bigger transformer. Without a model the upgrade is chosen from the most visible asset rather than the element actually binding.
- Metered demand analysed across a representative cycle rather than taken from a single peak reading, since one peak says little about diversity.
- Every switching configuration studied as its own case, because a network comfortable on the normal arrangement can be constrained on the alternative.
- Motor starting assessed where large drives exist, as starting current depresses bus voltage for its duration and can breach limits a steady-state study passes.
- Transformer impedance taken from test certificates where available, because typical values shift voltage drop results materially.
- Power factor assessed as part of the position, since reactive demand consumes capacity that could otherwise carry useful load.

How the study runs
Frame the decision
We establish what must be settled: a demand review, a new production line, or a persistent voltage complaint at a specific point in the plant.
Establish real demand
Metered data is collected across a representative cycle and reconciled against connected load, since the gap between them is usually the finding.
Build the model
The network is modelled in ETAP from site-verified data, with transformer and cable parameters from certificates and schedules rather than defaults.
Solve the scenarios
Present operation, maximum demand, alternative switching and planned future load are each solved as separate cases.
Name the constraint
The first binding element is identified for every case with the margin remaining on it, which is what capacity planning actually requires.
Options and handover
Reinforcement, reconfiguration and compensation options are presented with the constraint each relieves, and the model is handed over.
