Real power and current of an individual circuit — an RTU, the refrigeration rack, the lighting panel — captured by a submeter. Turns the meter into a per-asset view: it attributes energy by end use and provides the baseline every equipment-health signal compares against.
The real power (kW) and current (A) drawn by an individual circuit — an RTU, the refrigeration rack, the lighting panel — captured by a submeter at the panel during the analysis period. It turns the whole-building meter into a per-asset view: it attributes energy by end use and provides the baseline every equipment-health signal compares against.
The calculation depends on the metering installed at each site. At Optimized, a submeter on the individual circuit reports real power and current directly — this per-circuit metering is the differentiator that makes per-asset attribution possible; the whole-building meter alone cannot separate one RTU from the rack.
Per-circuit power is read directly from the submeter; current is the RMS measurement on the same circuit. From the steady running power and current, a healthy baseline is established per circuit at commissioning (and re-established after a service visit or an equipment change), and every later reading is compared against that circuit's own baseline rather than against another site.
Attribution works from two sources only — the per-circuit telemetry and the utility bill. There is no weather or occupancy normalization in V1: a step-change against baseline is flagged for a walkthrough, not auto-attributed to ambient conditions. The exact thresholds and baselining logic vary by client depending on the equipment class, the metering point, and the integration.
| Range | Classification | Interpretation |
|---|---|---|
| Within ± baseline band | Expected | Circuit power and current tracking its own healthy baseline at like-for-like operating conditions |
| Step-change vs baseline (no known change) | Flag — scope a walkthrough | Consumption or run-fraction stepped up with no merchandising or load change; attribute to the exact circuit before product or comfort loss |
| Rising-current signature on the step | Degradation — book service | A circuit pulling more amps to do the same work; the earliest electrical sign of fouling, charge loss, or wear — schedule a visit, not an emergency dispatch |
| Circuit drawing during scheduled off-hours | Schedule / contactor fault | A load running when it should be off — a timeclock, control, or contactor problem to correct on site |
Reference examples only. Baselines and step-change thresholds are calibrated per client and per circuit based on equipment class, metering point, and operating hours before any alarm is activated. No customer benchmark is implied by these ranges.
There is no single portfolio compliance target for this metric — it is an attribution baseline, not a pass/fail KPI. The agreed target is the set of circuits submetered per site and the per-circuit baselines kept current; define both with each client at commissioning.
The table below shows how moving Per-circuit power & current impacts each customer value driver the product is designed to improve — the metric page explains the mechanism; the product pages express the magnitude.
| Value driver | Impact strength | How Per-circuit power & current moves this lever |
|---|---|---|
| Energy savings | Direct, primary | Per-circuit power is what turns a whole-building anomaly into an exact end use. Attributing kWh to the RTU, the rack, or the lighting panel is the only way to know which load to act on — and where the customer also runs Keedian on HVAC, Lighting, or Refrigeration, that attribution is what lets the connected product act on the right circuit. Energy Intelligence reads the meter; it does not command the load. |
| Avoided truck rolls | Direct, strong | A per-circuit step-change is attributed to the exact circuit before it becomes a complaint, so an emergency dispatch becomes a scheduled visit with the right scope already known. The same attribution separates a real circuit fault from a metering artifact or a utility-side issue — avoiding the truck roll that diagnoses nothing. |
| Asset lifespan | Indirect, leading indicator | Per-circuit current is the baseline every equipment-health signal compares against — short-cycling and cycling frequency both read off this circuit. Catching the step-change or the rising-current signature weeks early lets the customer correct the root cause (fouling, charge loss, a schedule fault) before the equipment is damaged. |
The table below summarizes the alarms that fire directly from Per-circuit power & current. Each row links to the full operational detail (trigger, preconditions, action plan, human role, escalation, prevention) in the SOPs catalog.
| Alarm | Description | Severity | Tier | AI executes? | Value drivers | SOP |
|---|---|---|---|---|---|---|
| Per-circuit consumption step-change | A sub-metered circuit's consumption or run-fraction steps change with no merchandising or load change. | High | Optimized | Hybrid | Avoided truck rolls · Asset lifespan · Energy savings | Open SOP → |
More alarms in development (single-metric): off-hours circuit draw as a standalone alarm. The equipment-health signals that compare against this per-circuit baseline — short-cycling, service-voltage and power-factor power-quality alarms — are documented on their own metric pages. Composite FDD that combines per-circuit current with control state will appear in a future release.
The action plan for each alarm lives on its own SOP page in the SOPs catalog — with the diagnostic steps, human role, value drivers, escalation, and prevention specific to that alarm. The list below maps each alarm to its SOP.
Attribute the step to the exact circuit, scope the equipment check, and convert an emergency truck roll into a scheduled visit — the full diagnostic sequence, human role, and escalation criteria live on the SOP page.
If a circuit's power or current looks implausible, or the per-circuit readings don't sum toward the whole-building meter, treat the attribution as unreliable before acting on any alarm. A CT clamp on the wrong circuit, a reversed CT, or a wrong CT ratio biases every signal that compares against this baseline. Escalate internally to the technical team, exclude the affected circuit from the period, and confirm the metering point before reporting anything to the client.
Reconcile attributed circuit energy and total metered kWh against the utility bill each cycle. A divergence beyond tolerance can be a CT-ratio or multiplier error or a billing mistake worth recovering — present the finding to the customer rather than absorbing it as a circuit fault. This is a portfolio-level reconciliation, not a per-circuit dispatch.
When a circuit's equipment is serviced or replaced, or merchandising changes the load, the old baseline no longer holds and a step-change against it is expected behavior, not a fault. Re-baseline the affected circuit and note the change so it is not reported as an anomaly. This keeps every downstream equipment-health signal honest.
Per-alarm escalation criteria live in the Escalation block of each SOP in the SOPs catalog. The patterns below are metric-level — read from the portfolio view, not from any single alarm firing.
