Precision Metering as the Enabler of Dynamic Load Management

Date: January 19, 2026

Dynamic Load Management (DLM) is a hardware-dependent, software logic control strategy designed to overcome the existing finite capacity of the existing electrical service infrastructure. By shifting from static and fixed power allocation to real-time capacity management, DLM supports high-density EV charging without expensive transformer upgrades. This white paper presents the theoretical framework for DLM, the closed-loop mechanism for controllers, and the supporting Accuenergy products to maximize power utilization.

Key Highlights

Optimize capacity allocation by reallocating unused building power to EV chargers based on real-time demand.
Monitor Total Harmonic Distortion (THD) to prevent overheating in transformers due to non-linear loads.
Sub-second telemetry acquisition with high speed Acuvim II meter at 100ms update rate to detect transient spikes from HVAC systems and prevent nuisance trips.
Precise guard band reduction to reclaim usable system capacity with Acuvim EL Class 0.2S and Acuvim II Class 0.1 meter.
High density monitoring and granular optimization of up to 24 single-phase circuits using a single AcuRev 4100 series meter.
