Residential
Home electrical needs are often practical and personal: safer circuits, panel improvements, dependable lighting, EV charging, and clear explanations before work starts.
ABOUT TERGRES ELECTRIC
Broad electrical experience. Practical solutions.
Electrical needs vary from homes to businesses to industrial facilities. Our approach starts with the same fundamentals: understand the challenge, explain the options, and define the work carefully.
THE TERGRES PERSPECTIVE01 / 03
OUR FOUNDATION
Experience that spans more than one environment.
TERGRES Electric was built on the idea that good electrical service combines technical knowledge with practical thinking and clear communication.
The experience behind TERGRES includes commercial electrical installations, industrial facilities, electrical equipment and controls, and utility distribution systems. Earlier work involved commercial lighting, emergency power projects, industrial power systems, equipment selection, and electrical distribution. It later expanded into major transmission infrastructure and engineering leadership.
Those different environments call for different solutions—but they all benefit from understanding the customer's needs, identifying the relevant electrical requirements, and setting expectations before work begins.
A BROADER PERSPECTIVE
Experience across real electrical environments.
From home electrical needs to commercial installations and industrial power equipment, the experience behind TERGRES connects technical knowledge with real-world priorities.
Commercial
Past work included coordinating commercial electrical installations, lighting projects, emergency generation, and energy-audit proposals for business properties.
Industrial
Experience includes work on LNG and combined-cycle power projects, substations, protection testing, and energy-efficiency studies for industrial motors and pumps.
REAL-WORLD TECHNICAL FOUNDATION
Experience with the equipment behind the systems.
Earlier professional assignments covered both customer-facing electrical equipment and the systems that keep buildings and facilities operating.
Equipment & controlsMedium-voltage switchgear, transformers, protection relays, motor drives, PLCs, circuit breakers, and SCADA systems.
Commercial & industrial projectsCommercial lighting, emergency power generation, industrial plant engineering, and electrical energy audits.
Distribution & reliabilityDistribution transformer improvements, substation engineering, protective-device testing, and electrical-system efficiency.
These examples describe the founder's prior professional experience—not projects completed by TERGRES Electric. The current service directory focuses on residential electrical work. Commercial and industrial inquiries are evaluated individually based on available capabilities and applicable requirements.
THE TERGRES APPROACH
Clear thinking. Practical execution.
Regardless of the setting, we believe a good project begins with a straightforward process.
01

Listen carefully, assess the circumstances, and identify what the customer wants to accomplish.
02
Define a clear scope
Explain the relevant options, requirements, and recommended steps before work begins.
03
Deliver with care
Approach the approved work with attention to safety, quality, communication, and the property itself.

Built on experience. Focused on your project.
TERGRES Electric is built on more than 18 years of specialized electrical engineering and infrastructure experience. Founded by Grester Garcia, P.E.—a Licensed Professional Engineer and Licensed Electrical Contractor—the company bridges the gap between high-level engineering theory and hands-on field execution.
While our deep background spans complex commercial installations, industrial controls, and large-scale power generation, we are committed to bringing that rigorous, utility-grade standard to projects of every scale—including comprehensive residential electrical work. Because we have engineered, protected, and troubleshot critical power systems from the ground up, we bring an unmatched level of safety, precision, and reliability to your home or business.
Whether we are upgrading a residential electrical panel, wiring a new build, or consulting on broader commercial installations, TERGRES operates on four straightforward principles: understand the need, clearly define the work, explain the options, and execute with care.
