Where the demand goes.
A common discovery: 80% of a building's peak demand comes from 4 circuits. Signal names them, schedules around them, and credits the cost to the right cost center.
Demand charges are 30-60% of most commercial electric bills. Without circuit-level metering, you cannot tell which tenant, floor, or system is responsible. Signal pairs to standard power meters and allocates every dollar.
Four core capabilities for tenants, controllers, and operators.
Sub-metered allocation with exportable invoices. Tie to lease terms. Catch rate-class arbitrage.
Real-time demand against your tariff threshold. Pre-peak alerts, automatic load-shed integration if you have controllable loads.
IEEE 519 compliance scoring. Identify VFDs and other non-linear loads creating distortion. Catch power-factor penalties.
Reconcile utility billing against measured demand and consumption. Catch meter-multiplier errors and tariff misclassifications.

How this looks in your stack.

On-premise by default. Cloud-deployable when required. Your facility data never leaves your network.
TLS everywhere, secrets in vault, row-level security on every query. Containerized and isolated so one service going down never takes the rest with it.

Engineer and operator questions on this capability.
Schneider PowerLogic, Veris H8035/H8163, Eaton IQ250, Siemens 9410, Square D PM5000 series, plus anything Modbus or BACnet-IP that exposes power and energy registers.
For sub-metered tenant billing, yes. Signal generates invoices and integrates with property management systems via REST or CSV.
The standard for harmonic distortion limits at the point of common coupling. Signal scores compliance and identifies offending loads.
If you have meters, Signal pulls from them. If you do not, we recommend an instrumentation pass before deployment.
Demand and energy work together. Bill validation needs both.
