The Economic Benefits of Active Harmonic Filters for Your Business

Quality Energy • Sep 05, 2023

Amid the rising costs of doing business, it is essential for Australian businesses to optimise every aspect of operations to make the most of every dollar. Power quality, often overlooked, is a hidden factor that significantly impacts both productivity and costs. Active Harmonic Filters (AHFs) are a solution that not only enhances power quality but also offers tangible economic benefits. This article explores the return on investments (ROI) when implementing AHFs, highlighting the financial gains Australian businesses can achieve over time by prioritising power quality improvement.

About Power Quality

Power quality, which refers to the reliability and stability of electrical supply, directly affects the efficiency and longevity of equipment. Harmonic distortions, voltage fluctuations, and other anomalies can lead to equipment failures, operational disruptions, and increased energy consumption. This then translates to hidden costs in your electricity bill through demand charges that escalate over time, eroding your business’ profitability.

Understanding Active Harmonic Filters

Active Harmonic Filters are dynamic devices that combat power quality issues. AHFs neutralise harmonic distortions and ensure a clean power supply by actively monitoring electrical waveforms and injecting counteractive currents. While the immediate benefits are evident in improved equipment performance and power quality, the long-term financial gains of Active Harmonic Filters are equally noteworthy.

Quantifying the ROI of AHFs

Calculating the ROI of AHFs require a comprehensive assessment that considers various factors:

  • Energy savings: Harmonic distortions lead to increased energy consumption. AHFs optimise energy usage by mitigating these distortions, reducing electricity bills.
  • Equipment longevity: Harmonic-induced stress contributes to premature equipment failures. AHFs extend equipment lifespan, reducing the frequency of replacements and maintenance expenditures.
  • Operational continuity: Unplanned downtime can be detrimental to productivity. AHFs help to improve power quality, leading to uninterrupted operations and higher output levels.
  • Reduced maintenance costs: Equipment subjected to harmonics requires frequent maintenance. AHFs decrease wear and tear, leading to lower maintenance costs over time.
  • Power Factor Correction: AHFs enhance power factor, which impacts energy efficiency. Improving power factor can lead to lower reactive power charges on electricity bills.
The Data-Driven Approach

To effectively demonstrate the ROI of AHFs, businesses should consider the following steps:

  • Baseline assessment: Conduct an initial power quality assessment to understand the extent of harmonic distortions and power anomalies present in the system.
  • AHF implementation: After implementing AHFs, monitor power quality changes and gather data on energy consumption, equipment performance, and operational continuity.
  • Energy savings calculation: Compare energy consumption before and after AHF implementation. Calculate the energy savings achieved due to reduced harmonics and improved power factor.
  • Maintenance and equipment cost reductions: Track the frequency of equipment failures and maintenance requirements before and after AHF installation. Calculate the cost savings from reduced maintenance expenses and equipment replacements.
  • Operational continuity analysis: Quantify the impact of AHFs on downtime reduction. Calculate the potential revenue gain from uninterrupted operations.
  • ROI calculation: Combine the calculated energy savings, maintenance cost reductions, operational continuity gains, and power factor improvements. Divide this total benefit by the initial investment in AHFs to determine the ROI percentage.
