Automatic · Intelligent · Always working for you
Your AC, water heater, dryer, and EV charger already switch on and off all day. The DAC — Demand Automation Computer — is the smart conductor that makes them take turns instead of surging together, so you never hit the brief, expensive spikes that set your bill. Same comfort. Lower peak. Real savings.
High demand = high bills
When the AC compressor, water heater, and dryer all surge on in the same moment, your demand spikes — and on any rate with a demand charge, that brief peak sets what you pay all month. The DAC's job is simple: keep that peak from ever happening.
Billed peak: 13.1 kW — one bad moment, priced all month
Billed peak: 5.4 kW — everything still ran, nothing spiked
Not sure how your utility charges you? Take the 60-second fit check and we'll figure it out together.
Meet the conductor
Installed at your electrical panel, the DAC watches your whole home's real-time demand and quietly sequences your biggest loads so they cycle in turn instead of stacking. Nothing is denied — it's shifted by minutes, on loads you won't perceive.
Whole-home demand right now
Monitoring your whole home 771× per second
Measures your entire home's demand at the service entrance — 771 times per second, with millisecond precision.
Computes your instantaneous demand in kilowatts and projects where your average is heading.
If demand is rising too fast toward your limit, it decides which load to hold — lowest priority first.
Briefly holds or shifts that load in the background, then restores it the moment headroom opens up.
Your demand stays below the limit. You avoid high demand charges — automatically, all month long.
The DAC continuously measures your home's total electrical demand at the service entrance using current transformers on the incoming mains, so it always knows your real-time load in kilowatts against a setpoint you've defined. Every large load in the house — the heat pump, backup heat, water heater, dryer, EV charger — is assigned a priority.
As demand rises toward your limit, the controller sheds the lowest-priority loads first, holding them off just long enough to keep you under the threshold, then restores them in order as headroom opens back up. Because it's coordinating the whole service rather than switching one circuit blindly, it sequences loads so they cycle in turn instead of stacking simultaneously — which is what creates the brief current spikes that set your peak.
Nothing is denied operation; it's shifted by minutes, on the loads you won't perceive. The result is a flattened demand curve and a lower billed peak — on any rate with a demand charge or tiered demand component, a meaningful and recurring line-item reduction.
The fit check
10 quick questions, about 60 seconds. We'll score how much a DAC could do for you — and back it up with your utility's actual rates.
Question 1 of 10
The orchestra
Your home's biggest loads already cycle on and off all day. The DAC simply decides when — so they take turns instead of surging at the same moment.
Compressor cycles are sequenced — and supercooling can hold resort-like temperatures while you save.
Heats between peaks. Your water stays hot — the tank never notices a few shifted minutes.
Heating elements yield briefly when the home is surging, then pick right back up.
Your car charges around the peaks and is always ready when you are.
Runs its full schedule — just never in the same breath as everything else.
Resistance strips are staged in, not slammed on — the single biggest spike-maker, tamed.
Everything still runs and does its job. Loads are shifted by minutes — never denied.
The result
Your billed peak drops because the spike that sets it never happens.
A recurring, line-item reduction — month after month, automatically.
72° super-comfort. Hot showers. Dry laundry. A charged car. You won't notice a thing — except the bill.
Solar shrinks your usage; the DAC shrinks your peak. Together they attack both halves of the bill.
No app to babysit, no schedules to program. It decides 771 times a second so you never have to.
Heat waves, cold snaps, holiday laundry marathons — the DAC is watching every second of every day.
Questions
No. The DAC manages the loads you won't perceive — a compressor cycle, a water-heater element, an EV charger — and shifts them by minutes, not hours. Everything still runs and does its job; it just takes its turn instead of piling on.
Your comfort stays exactly the same. In fact, DAC customers often supercool — enjoying resort-like temperatures — because with the peak managed, comfort no longer costs a spike.
Many utility rates bill you not just for total energy used, but for your single highest moment of demand during the billing period. One 15-minute surge — AC, dryer, and water heater all at once — can set a charge you pay for the entire month.
Yes. Solar reduces how much energy you buy; the DAC reduces your peak demand. They solve different halves of the bill and work great together — but the DAC saves money with or without panels.
No. Once your demand limit is set, the DAC monitors, calculates, decides, and controls on its own — every second, 24/7. You just enjoy the smaller bill.
