Peak Demand Optimisation

Stop Paying Penalties
for Power You
Almost Didn’t Use.

Every large building has a licensed maximum demand. Exceed it — even once, even briefly — and you pay a penalty for the whole month. SmarterHU monitors your demand in real time, predicts approaching peaks, and sheds load automatically before the breach is recorded.

The Problem

Exceeding your MD costs you far more than you think.

Demand penalties aren’t just a line on the bill. They cascade into compliance costs, infrastructure obligations, and capital expenditure that compounds over years.

01. Demand Penalty Charges
Exceeding licensed MD triggers a penalty — typically 1.5x to 2x the normal demand rate — for the entire billing month, not just the breach duration.
02. Over-Licensing to Stay Safe
Without monitoring, most buildings license more demand than needed — paying fixed charges for capacity never used, month after month.
03. Substation Infrastructure Cost
Higher licensed demand requires larger transformers, switchgear, and cabling. Oversizing means significant upfront capital that could be avoided.
04. Land & Civil Obligations
A higher MD licence may require a dedicated substation on your premises — land acquisition, civil construction, and ongoing maintenance.
05. Compliance & Social Obligations
Large utility connections above certain MD thresholds trigger additional safety inspections, utility agreements, and environmental obligations.
06. Demand Ratchet Clauses
Many tariffs include ratchet clauses — reach a new peak and your minimum billed demand rises and stays elevated for 12 months.
Understanding Maximum Demand

It’s not about how much you consume. It’s about how much you pull at once.

Maximum demand is not your total monthly energy consumption — it’s the highest rate at which you draw power during any 15-minute window in the billing period. One spike on one morning can set your demand charge for the entire month.

01. How MD is measured
Your utility meter records average power draw in every 15-minute window throughout the month. The highest single 15-minute average becomes your recorded maximum demand — and sets your demand charge.
02. When breaches happen
Breaches almost always occur during simultaneous machine startups — chillers, AHUs, pumps, and fans all starting together in the morning. The spike lasts minutes, but the penalty lasts the whole month.
03. The license you really need
Most buildings are licensed for more demand than they need — because without data, facility managers add a buffer. SmarterHU shows your real peak pattern so you can license exactly what you need.
The 15-minute window that changes everything
A single 15-minute period where your demand exceeds licensed MD — even if every other window was within limits — triggers the full demand penalty for the billing period. This is why real-time monitoring and proactive load shedding are critical.
Demand Profiling & Analysis

See exactly when and why your demand peaks.

Know your peak. Know its cause.

Most facility managers don’t know their actual peak demand profile — they see the monthly bill but not the hour-by-hour data behind it. SmarterHU gives you granular 15-minute demand data for every day, overlaid with individual machine contributions.

15-minute demand tracking
Continuous kW demand monitoring in every 15-minute window — the same interval your utility uses to calculate your peak.
Machine-level demand attribution
Identifies which machines are contributing to the current demand — so you know exactly which to shed when approaching a breach.
Time-of-day peak patterns
Reveals whether peaks are morning startups, afternoon coincidence, or evening ramp-downs — enabling targeted scheduling fixes.
Monthly demand history
12-month rolling history shows whether your licensed MD is justified by real usage — or whether you're over-licensed and overpaying.
Demand Control Strategies

Four ways SmarterHU keeps your demand within limits.

SmarterHU doesn’t just alert you when demand is high — it acts. Four automated strategies ensure your demand never exceeds its licensed limit.

Staggered Machine Startup

The single biggest cause of breaches is all machines starting simultaneously. SmarterHU staggers startup across 10–20 minutes — the demand spike simply never forms.

Prevents 70% of breaches

Real-Time Load Shedding

When demand trends toward the limit, non-critical loads are automatically shed — exhaust fans, ventilation, non-essential AHUs — before the 15-minute window closes.

Automated & instant

Predictive Demand Forecasting

Using historical patterns, current load data, and weather inputs, SmarterHU predicts when demand is likely to peak — and takes preventive action before the spike occurs.

Forecast-driven

Off-Peak Load Shifting

Moves non-time-critical high-demand operations — pre-cooling, pump scheduling, storage charging — to off-peak windows where demand headroom exists.

Tariff-aware

MD Licence Optimisation

You may be licensed for more than you actually need.

Right-size your licence. Right-size your costs.

Your licensed MD determines more than demand charges. It sets the specification for your transformer, your switchgear, your substation — and in many cases, your obligation to dedicate land or pay for infrastructure on behalf of the utility.

With SmarterHU showing your real demand profile, you can approach your utility with data — not estimates — and negotiate a lower MD licence.

How It Works

From meter to managed demand — automatically.

SmarterHU connects to your main incomer meter, profiles your demand, enforces limits proactively, and gives you the data to right-size your licence.
