Onics Passive Harmonic Filter Installation Process

The Onics Energy Solutions team has developed a seamless process from our first site visit to installation of the Onics Passive Harmonic Filters in your facility.

The Onics Energy Solutions team has developed a seamless 5-step process from our comprehensive site walkthrough to certified, objective verification of your facility’s energy savings after installing the Onics Passive Neutral and Ground Harmonic Filters. We pride ourselves on providing full transparency and consistent communication to ensure all stakeholders are aligned. Our results are verified by a certified, third-party Measurement and Verification (M&V) Energy Experts and backed by raw data obtained directly from the electric utility.

Pre-Installation: Single Line & Electric Spend Review

Your facility provides Onics with the most recent single line diagram and a 24 month summary of electric spend and consumption. An Arc Flash study is optional but helpful in determining an installation plan prior to visiting the site. Onics reviews the facility information to estimate equipment and labor needs for the installation. Onics will also review the utility data to calculate potential energy savings, ROI scenarios, and CO2e offset.

The Onics team presents a project proposal with a one-time project installation fee estimate to your team and explains the installation process and timeline in more detail.

Upon completion of the Master Services Agreement, Onics will begin its seamless installation process with a dedicated Onics Project Manager running point for our installation teams and support staff. In addition, Onics will deploy trained Subject Matter Experts (SMEs) to facilitate the process in person.

Step 1: Comprehensive Site Walkthrough

Onics will coordinate with pre-approved licensed electrical contractors to conduct a comprehensive walkthrough of the facility in order to:

  • Confirm the equipment estimate taken from single line diagram

  • Identify potential installation location(s) for the Power Monitoring System

  • Identify potential installation challenges for Power Monitoring System and Onics devices

  • Formulate an installation plan for Power Monitoring System and Onics devices

Based on the finalized count of equipment, the estimate for the one-time installation fee of the project may be subject to revision.

Following the site walkthrough, Onics will present a comprehensive report to your team and proceed to schedule the Power Monitoring System installation.

Step 2: Power Monitoring System Installation

Onics coordinates with licensed Electrical Contractors (ECs) to prepare the installation locations in the facility for the Power Monitoring System.

Once the locations are prepped, Onics deploys a Subject Matter Expert (SME) and ECs to the facility on a pre-determined date to complete the installation of the Power Monitoring System(s). Each system is installed at the meter or switchgear and takes about 1-2 hours for a complete installation.

A reporting period of at least 30 days follows the installation of the Power Monitoring System to provide insights into the facility’s power quality and consumption.

Step 3: Measurement & Verification Energy Consumption Baseline Established

During the Reporting Period, Onics will engage an independent, third-party Measurement & Verification (M&V) Energy Expert to calculate an energy consumption baseline based on:

  • Utility interval metering data

  • Facility / operational data

  • Independent variables such as temperature or humidity

  • Note: Data collected by the Monitoring System is only used to identify anomalies in energy usage and will not be used in M&V analysis

The M&V Energy Expert will schedule a video conference with your team to review their methodology, calculations and energy baseline findings, providing an open forum to ask questions and gain clairty on the process. 

Onics will send your team a digital version of the Energy Baseline Report for eSignature approval.

Step 4: Onics Passive Harmonic Filter Installation

Onics will deploy SMEs and a team of licensed ECs to install the Onics Passive Neutral and Ground Harmonic Filters on every neutral and ground application throughout the facility. Examples of ground applications where the Onics Passive Harmonic Filters can be installed include:

  • Variable Frequency Drives (VFDs)

  • Programmable Logic Controllers (PLCs) 

  • Uninterruptible Power Supplies (UPS)

  • Soft Starts

  • Ground-referenced lighting and single phase systems

  • Other electronic 3-phase systems

Each device is hardwired in parallel with neutral or ground and takes an average of 15-30 minutes to install. Because the Onics device is passive, inductive and installed on the cold side of the panel, there is virtually no need for a facility shutdown to install, but de-energization is recommended if possible to ensure the safety of the installation teams.

A minimum reporting period of 30 days follows the installation of the Onics Passive Neutral and Ground Harmonic Filters. The M&V Energy Expert will determine the necessary length of the reporting period to ensure sufficient data collection.

Step 5: Measurement & Verification Final Energy Savings Report

Following the Proof of Concept Period, the M&V Energy Expert will request an updated batch of interval metering data from the electric utility and facility / operational data for analysis. 

With this data, the M&V Energy Expert will calculate a validated energy savings as a percentage reduction in kWh.

The M&V Energy Expert will schedule a video conference with your team to review the Final Energy Savings Report. 

Onics will send your team a digital version of the Final Energy Savings Report for eSignature approval.
