Energy Eight engineers the world's most advanced passive harmonic filters — eliminating electrical waste at the source and delivering guaranteed energy savings for commercial, industrial, and government facilities.
Modern facilities are filled with non-linear loads — VFDs, LED lighting, computers, HVAC systems — that inject harmonic distortion into your electrical infrastructure. The consequences are silent, cumulative, and extremely costly.
Harmonic currents create excessive heat in motors, transformers, and wiring — dramatically shortening equipment lifespan and triggering unexpected breakdowns.
Distorted power factor and reactive current demand force utilities to supply more power than your facility actually uses — you pay for waste you never needed.
Harmonic interference trips breakers, corrupts sensitive electronics, and brings production lines and data systems to a halt at the worst possible moments.
Third-order harmonics accumulate on neutral conductors, exceeding design ratings and creating serious fire and safety hazards — often hidden inside walls and conduits.
The OES Passive Harmonic Filter installs in parallel on every neutral and ground application throughout your facility — eliminating distortion at its source, not downstream.
The OES-11 and OES-23 are proprietary passive harmonic filters engineered to neutralize harmonic distortion across every neutral and ground circuit in your facility — with zero moving parts and zero maintenance requirements.
Every deployment comes with a documented minimum energy savings guarantee. Most facilities achieve 10–20% or more.
Filters install in parallel at the point of harmonic generation — not downstream. More effective than centralized solutions.
Fully UL certified with multiple industry certifications demonstrating safety, reliability, and technological innovation.
Reduce your carbon footprint and support Environmental, Social, and Governance initiatives with measurable energy reduction.
Our multidisciplinary team delivers a complete turnkey solution — from initial power quality assessment through deployment and ongoing performance verification.
Our engineers conduct a comprehensive audit of your facility's electrical infrastructure — measuring harmonic levels, power factor, load profiles, and identifying the highest-impact intervention points.
OES filters are configured and installed in parallel across your neutral and ground applications. Our certified technicians handle the full turnkey deployment with zero disruption to your operations.
Post-installation measurements document your actual energy reduction. We operate on a shared savings model — our success is tied directly to yours, ensuring a long-term performance partnership.
Anywhere non-linear electrical loads operate at scale, harmonic distortion is a problem. Our solutions are deployed across the most energy-intensive facilities in every sector.
Energy Eight is fully registered on SAM.gov and CAGE-coded for federal procurement. Our passive harmonic filters qualify under multiple NAICS codes covering electronic component manufacturing and power management equipment.
Our solutions support federal energy efficiency mandates, including requirements to reduce energy intensity across government buildings and military installations. The shared savings model aligns perfectly with performance contracting frameworks used by federal agencies.
From GSA Schedule opportunities to direct agency contracts, our team has the credentials and experience to navigate government procurement efficiently.
Contact Government Sales →Founded in 2015, Energy Eight LLC was built on a single conviction: that the electrical waste caused by harmonic distortion was an enormous, largely invisible problem that deserved an equally innovative solution.
Operating in partnership with ONICS Energy Solutions, our multidisciplinary teams bring together electrical engineers, project managers, and energy analysts to deliver complete turnkey deployments. We don't just sell a product — we manage the entire process from assessment through verified savings documentation.
Every OES filter is manufactured in our facility outside Atlanta, Georgia — ensuring consistent quality, domestic supply chain integrity, and American jobs.
Work With Us →Our engineers will analyze your facility's electrical profile, identify harmonic distortion sources, and deliver a detailed report showing your potential energy savings — at no cost or obligation.
