Hybrid Power Quality (HPQ) uses multiple technologies - active and passive systems - to improve overall power quality in electrical networks. It's called 'hybrid' because it integrates the strengths of different solutions to manage various power quality issues more effectively and cost-efficiently.
Our Hybrid Power Quality (HPQ) solution is perfect for situations where you need both dynamic reactive power compensation and harmonic mitigation to achieve a well-balanced, efficiency-optimised power supply for your business. For example, industrial plants with both heavy motors and nonlinear loads (VFDs, welders) and commercial buildings with high harmonic content, unbalanced loads and leading Power Factors.
What we offer
Our Hybrid Power Quality service covers everything – from an initial survey and analysis, through to bespoke design, build, installation, and on-going maintenance.
-
Inspect & analyseA detailed on-site survey by a highly qualified engineer, followed by in-house skilled analysis of our findings, giving you a clear proposal and scope of work.
-
Design & buildAll our PFC equipment is custom-made by real people (not robots!) using time-honoured tools and skills in our professional workshops.
-
Quality approvalsEverything we produce is subject to stringent quality, performance and safety testing in line with industry directives, regulations and standards.
-
Supply & installOur power quality engineers will deliver and install your new power factor correction equipment within your electrical system, test and handover.
-
Service & maintainWe offer on-going technical support and service packages to maintain maximum efficiency and superior performance, backed up by our 2-year parts warranty.
-
Hybrid power qualityOur hybrid power quality services don’t just apply to new installations. Much of our work involves revisiting sites where existing equipment needs re-surveying and updating to ensure its better optimised.

Merus Hybrid Power Quality
We install Merus® HPQ to give you the best of both worlds. It's an all-in-one solution that combines a reliable detuned capacitor bank with a modern active harmonic filter. Working together to keep your power clean and efficient.
The capacitor bank covers most of your reactive power needs, while the active filter fine-tunes performance - making smaller adjustments so taking care of both inductive loads and harmonics. It's a smart, balanced way to improve power quality without overcomplicating things.
The benefits
Where the application requires it, Hybrid Power Quality delivers all the benefits of Power Factor Correction, Active Harmonic Filtering, and more.
Our Hybrid Power Quality solution seamlessly combines active power quality (AHF) and passive power quality (PFC) to achieve the very best result.
Reducing reactive power cuts down energy waste and lowers electricity bills. With HPQ, the initial set up costs are lower and payback is quicker.
Greater efficiency means using less energy. The optimum PFC system can attract a reduction of 5% in the total CO₂ emissions for a building.
Many energy providers charge penalties for wasting energy. Power factor correction can eliminate this.

Only one device needed – PFC and AHF combined into one cubicle optimises valuable space.

Read MoreHybrid Power Quality is a combined solution that integrates Active Harmonic Filtering and Power Factor Correction into a single system to ensure clean, stable, and efficient electrical power across diverse load conditions.
Combining these two functions addresses both harmonic distortion and reactive power issues simultaneously – improving overall power quality, reducing energy losses, and protecting sensitive equipment.
It tackles key issues like harmonic distortion, low power factor, voltage instability, and overheating of electrical components—especially in environments with variable loads or renewable energy integration.
Industrial plants, commercial buildings, and facilities with mixed or fluctuating power demands – such as those using VFDs, large motors, or renewable energy sources – benefit significantly from this all-in-one solution.
It enhances energy efficiency, extends equipment life, ensures compliance with grid standards, reduces penalties from utilities, and provides a cost-effective, space-saving alternative to using separate systems.
