The Problem
Hotels are uniquely sensitive to power quality. Unlike a factory, your guests feel the symptoms: flickering lights in ballrooms, audible transformer hum in quiet corridors, HVAC temperature swings, lift jerking, and electronic lock malfunctions. These issues erode satisfaction scores and repeat bookings — and most hotel teams never connect them to the electrical network.
Meanwhile, 8–18% of your electricity spend is being wasted as heat in cables, transformers, and motor windings, driven by the very equipment designed to make your property efficient: VFD-controlled HVAC, LED dimmers, commercial kitchens, laundry systems, and the growing fleet of EV chargers in your car park.
What Causes It
Every VFD-controlled chiller, LED dimmer, switch-mode power supply, and EV charger draws current in non-linear pulses that distort the smooth 50/60 Hz sine wave. Hundreds of these loads operating simultaneously create harmonic distortion — electrical “noise” that wastes energy and stresses every component in your building’s electrical system.
EV charging — the growing power quality challenge + Read more− Close
EV charging is projected to reach 5–8% of hotel electrical load within 3–5 years. Each Level 2 charger draws 7–22 kW with 25–35% current THD from its rectifier. A hotel installing 10 chargers adds 70–220 kW of harmonic-rich demand. Without power quality management, this can push facility THD beyond compliance limits and trigger demand ratchet charges that persist for months after a single peak event.
The Solution
HarmoniQ uses a patented narrowband tuning approach to maintain clean, efficient power across your entire property. Our system monitors your electrical network 20,000 times per second and dynamically adjusts to keep current flowing at a pure 50/60 Hz — eliminating the distortion that wastes energy and damages equipment.
The system installs in parallel at your main switchboard with zero disruption to hotel operations. No guest-facing impact. No power interruptions. No ongoing maintenance.
Eliminates harmonic distortion from VFDs, LED drivers, and EV chargers in real time, reducing THD to below 5%. Quietens transformer hum, extends equipment life across the property, and future-proofs your electrical infrastructure for EV charging growth.
Stabilises voltage 20,000 times per second, eliminating light flicker, HVAC temperature swings, and electronic system glitches. Protects the guest experience by keeping BMS, lighting, and access control systems running on clean, stable power.
Corrects power factor to 0.98+, eliminating reactive power penalties. Particularly effective at managing the partial-load power factor degradation that dominates hotel electrical profiles during off-peak hours.
The Impact
| Metric | Before | After HarmoniQ | Improvement |
|---|---|---|---|
| Power factor | 0.82 | 0.98 | +19.5% |
| Voltage THD | 5.8% | 2.4% | −59% |
| Peak demand (kVA) | 1,037 | 867 | −16.4% |
| Annual electricity cost | $535,000 | $455,000 | −$79,000 |

Beyond the Bill
Clean power means chillers, lifts, LED lighting, and kitchen equipment last 20–35% longer. A single chiller replacement costs $190,000–$510,000 — extending its life by even a few years pays for HarmoniQ many times over.
A typical 200-room hotel reduces emissions by 38 tonnes of CO₂ per year. That’s a measurable contribution to your brand’s net-zero targets, BREEAM In-Use score, and the sustainability credentials that 73% of travellers now factor into their booking decisions.
