Energy Intelligence for Industrial Leaders
Power quality guides, energy efficiency strategies, and industry analysis from HarmoniQ's engineering team.
The Seven Sins of Power Quality
Seven distinct physical phenomena corrupt the sine wave in every industrial electricity supply. Each one costs money, each one causes damage, each one is correctable. The complete taxonomy — physics, cost, and remedy.

Four foundational pieces. Read these to understand the problem, the physics, what differentiates us, and the ESG lever behind everything else on this page.
Technical Reference
Understanding HarmoniQ: The Physics of Clean Current
The three types of current distortion, how HarmoniQ corrects all three across the entire network, and the standards we meet.
Technology
Why Capacitor Banks Don't Solve the Full Problem
Capacitor banks compensate reactive power at the meter point. Modern industrial facilities have several more power quality problems that capacitor banks cannot touch.
Equipment Life
The IEEE Arrhenius Rule: Why Every 10°C Matters
How reducing operating temperature by 20°C can double the lifespan of motors, transformers, and insulation systems — and what this means for your capital budget.
ESG
Scope 2 Emissions: The Fastest Lever Most Companies Overlook
Energy efficiency remains the highest-ROI path to Scope 2 reduction. We explain why power quality optimisation should be the first item on every sustainability roadmap.

Why Fixing Power Quality with Capacitor Banks at the Meter Isn't Enough
A correction device only cleans the current upstream of where it sits. Install it at the meter and your entire internal network — every cable, transformer, and motor — keeps carrying dirty current. Why location decides the result.

VSDs: The Harmonic Source Hiding in Every Modern Plant
Every pump, fan, and compressor on a variable-speed drive saves energy at the motor and injects harmonics on the line. How drives distort current — on both the line side and the motor side — and why the cost stays hidden.
How We Prove It: The On/Off Test
The most direct proof of a saving: switch the device on and off minutes apart and measure the same load both ways. How the on/off test holds the world still — and where it hands over to weather-normalised regression.

Latin America's Industrial Power Bill: Reactive-Power Floors and the Drought Factor
In Latin America the reactive-power floor is written into the tariff, and hydro dependence makes price and reliability swing with the rains.

North America's Industrial Power Bill: Demand Charges and the Data-Centre Capacity Crunch
Across the US and Canada, poor power factor and peak demand are billed line items — and an AI and data-centre demand surge is making spare grid capacity suddenly valuable.

The Solar Blind Spot: How Clean Energy Creates Dirty Power
PV inverters inject 3–15% harmonic distortion into electrical networks, degrading power quality, damaging equipment, and partially eroding the financial return on solar investment.

Asia-Pacific's Industrial Power Quality Challenge: Demand Charges and the Rooftop-Solar Paradox
Demand and reactive-power charges put a direct price on poor power factor across Asia-Pacific — while the world's highest rooftop-solar penetration makes power quality an everyday low-voltage problem.

Weather Normalisation: Proving Energy Savings Are Real
Any facility can cut consumption in a mild winter. Real savings survive weather normalisation — the regression technique that isolates intervention impact under IPMVP and ASHRAE Guideline 14.

The Electrification of Everything: Why Global Power Demand Is About to Surge
EVs, heat pumps, data centres, and green hydrogen are driving a 75% increase in global electricity demand. What this means for industrial power quality.

Unlocking Grid Capacity Without Building New Infrastructure
Most industrial facilities waste 15–30% of their grid connection capacity on reactive power and harmonics. Here's how to get it back.

Africa's Industrial Power Paradox: Why the Grid Tariff Hides the Real Cost
Across much of Africa the published tariff is among the cheapest on earth — yet the real cost of power runs far higher, paid in diesel, downtime and damaged equipment.

The Science Behind the Savings
Our calculations, models, and claims are grounded in internationally recognised engineering standards. Explore the key standards and research that underpin HarmoniQ's technology.
