Electrical + Instrumentation Controls

The + is in Our Electrical Engineers.

We plan to succeed by beginning with the end in mind. Thorough project definition and planning with our client’s is vital to success.

Our Electrical professionals deliver full-service power distribution designs for industrial, utility, and commercial clients. Our regional offices support clients with engineering services for fast-paced and dynamic projects.

Over the past 40 years we have assisted clients with strategic planning, power system analysis, detailed design, and start-up assistance. We provide efficient and sustainable designs for generation, power distribution, grounding, lighting, motor control and communications.

The + is in Our Electrical Engineers

Harris Group’s integrated architecture and engineering design process results in efficient and well-coordinated design solutions that meet tight system start-up timelines. 

Our electrical design staff work as part of a multi-discipline team to provide coordinated designs with the mechanical equipment, architectural space planning, and process control elements of the project. We routinely work with critical power requirements and can provide power distribution solutions for demanding conditions worldwide.

Our team will deliver reliable power system and motor control designs for medium-voltage, and low-voltage design.   Additional specialties include electrical hazardous area classification, arc-flash hazard analysis and energy efficiency code compliance.



Our experience helps clients define electrical systems needed for their project. We use industry standard software to model new and existing distribution systems to determine electrical equipment requirements.

Detailed Design & 3D Modeling

Detailed design includes 3D modeling of cable tray systems and underground systems to ensure electrical system is coordinated with Architectural space planning and mechanical systems routing. Which proceeds with high confidence and a well-coordinated project for the client.

Comprehensive Approach

Our experience with greenfield projects, plant expansions, process optimization, and infrastructure retrofit projects provides you with expertise for all of your electrical systems requirements. Harris Group utilizes industry standard modeling software and field collected data to determine the electrical and control system requirements for your projects.

We review short circuit ratings, evaluate the system power available, and coordinate with the utility to provide the client a thorough design that is compatible with the existing site conditions. We consider the client’s electrical needs including, motor and system controls, arc flash evaluations, hazardous location installations, stand by and emergency power needs, energy efficiency, protective relaying, site grounding, and site layout for a comprehensive approach to client’s needs.
