Power Factor Correction
Eliminating Low Power Factor Penalties,
Automatic Capacitor Banks, and Industrial Capacity Optimization
Operating a commercial facility heavy on inductive loads—such as massive manufacturing motors, commercial refrigeration systems, and complex rooftop HVAC complexes—without automated correction hardware results in severe electrical grid inefficiencies. When your system draws excessive reactive power, it strains your internal distribution lines, causing localized voltage sags and triggering massive power factor penalty surcharges on your monthly ENMAX or utility billing statements.
At Electrek, our certified electricians deliver complete end-to-end commercial power factor correction solutions.
We conduct rigorous power quality assessments to map your system's real power (kW) against apparent power (kV A), then engineer and install custom-tailored automatic capacitor banks or harmonic-detuned correction networks. This optimization eliminates recurring utility penalties, instantly frees up vital panel capacity for operational expansion, and protects your heavy equipment assets from premature thermal breakdown.
Our Technical Power Factor Correction Services
We audit, design, and wire premium solid-state capacitor systems built to clean up inductive lag across your infrastructure:
Comprehensive Power Factor & kVAR Analysis
We hook up advanced power quality analyzers inside your main switchgear to log real-time power metrics under full operational load. We trace your displacement power factor across shifting work shifts, quantifying your exact real power (kW), reactive power (kV AR), and apparent power (kV A) to map out an exact mitigation plan.
Automated Multi-Step Capacitor Bank Installations
Inductive loads fluctuate as machinery cycles on and off. We install smart, automated switched capacitor banks equipped with digital microprocessors. These smart controllers continuously monitor your building’s line phase angles, automatically switching individual capacitor steps into the circuit to maintain a stable, optimal power factor target (typically ≥ 0.95) regardless of operational variance.
Harmonic-Detuned Filtering & Reactor Matrices
Modern facilities utilize non-linear loads like variable frequency drives (VFDs) and computer server stacks that inject harmonic distortion into the electrical grid. Standard capacitors can resonate dangerously with these frequencies, causing component blowouts. We engineer detuned reactor-protected capacitor banks that block harmonic currents, ensuring safe power factor improvement in electrically noisy environments.
System Restorations & Capacitor Cell Swaps
Power factor correction units are under extreme electrical stress, and their internal fluid-filled capacitor cells degrade naturally over time. We perform regular preventative maintenance, measuring current draws, cleaning contactors, and executing cell replacements to restore your legacy system back to peak protective efficiency.

Utility Penalty Eradication
The Direct Financial Impact
of Power Factor Optimization
In Alberta, utilities like ENMAX charge commercial clients heavily for drawing power inefficiently. If your facility's power factor drops below $0.90, your monthly distribution charges are artificially scaled upward based on your peak kV A draw rather than your actual kW energy consumption.
By installing an Electrek power factor correction system, you lift your performance parameters above this penalty threshold, dropping your monthly utility overhead instantly. Most commercial installations achieve full capital payback within 12 to 24 months purely through utility bill savings.
Frequently Asked Questions
What is the distinction between real power and apparent power?
Real power (kW) is the actual working energy consumed by your equipment to perform productive physical work—such as spinning a conveyor belt, compressing refrigerant, or illuminating a space. Apparent power (kV A) is the total raw current and voltage that the utility provider must deliver to your building envelope to keep those systems running, which includes the extra magnetic fields (reactive power) required by inductive motors.
Can a facility have too much power factor correction?
Yes. Over-correcting an electrical grid can cause a "leading power factor" state, which introduces dangerous over-voltage conditions and harmonic resonance risks back into your distribution system. This is why static, unmonitored capacitors are high-risk options; our modern, microprocessor-controlled multi-step systems dynamically match your real-time building demands, preventing over-correction.
Will installing a capacitor bank disrupt our active manufacturing schedules?
Not at all. The underlying data-logging and engineering assessments are performed entirely while your plant is live and operating normally. The final integration and wiring of the correction enclosure into your main switchgear bus can be effortlessly coordinated during off-peak weekend blocks or scheduled maintenance shutdowns to protect your production continuity.
