Peak Reduction
We bring your peak down, and keep it there.
Your demand charge follows the busiest 15 minutes of the month. We find the loads behind that interval, design the change on your own demand, run the control on site, and measure each month's peak on the panel.
What Sets a Peak
A peak is rarely one large machine. It is several ordinary ones landing in the same 15 minutes, and each of these can be moved without stopping the work they do.
- The Monday start-up
- After a weekend off, every floor's cooling comes on together with two days of heat to pull out. The week's highest interval often lands in the first hour of Monday.
- Loads that start together
- Rooftop units, compressors and a production line started inside the same 15 minutes. The charge is set by what coincides, so starting the same equipment in turns lowers it.
- Cooling on the hottest afternoon
- Every zone calling for cooling at once. Holding a setpoint a little higher for part of the interval, where the space allows it, takes the top off.
- Equipment running when nothing needs it
- Exhaust fans, water heaters and lighting still on during the busiest interval, adding to a peak they do nothing for.
How We Bring It Down
- 01 Peak Determination
- We read 12 months of your utility's own 15-minute record and find the interval that set each month's charge.
- 02 Investigation
- Meters on the key circuits show which loads make the peak, which must run, and which can move.
- 03 Intervention: Design
- Which loads change at the peak, and how many kW come off, simulated on your own demand before anything changes on site.
- 04 Intervention: Managed Capacity
- A licensed electrician fits the controller and any physical change. Wattif runs the control, keeps every protected load running, and measures each month's peak on the panel.
What You Receive
Peak Determination
The interval that set each month's charge, and what was running in it.
FirstInvestigation
Each load's share of the peak, and which of them can move.
NextIntervention: Design
The change, and the kW it takes off, simulated on your own demand.

Managed Capacity is quoted per site.
When a Peak Cannot Move
Some peaks are set by equipment that has to run when it runs: a cold room holding product, a line in the middle of a batch, life safety. Those are never on the list, and the investigation says so before anything is designed.
Where nothing can move without touching what must run, the peak stays where it is, and you know why.
