THE EVOLUTION
FROM EFFICIENCY TO GENERATION
Energy efficiency reduces what you consume. Solar and battery storage change how you produce and manage power. It's the next chapter in energy strategy — and where GEC focuses today.
Our efficiency background isn't just history. It's why we approach solar and storage differently. We understand load profiles, demand patterns, and building systems — because we spent decades optimizing them.

COMMERCIAL SOLAR EPC
Rooftop, ground-mount carport. Full turn-key delivery — engineering, procurement and construction under one roof.

BATTERY ENEGRY STORAGE
Demand charge reduction, backup power, solar integration. Systems engineered for your load profile.

MEP ENGINEERING
In-house licensed P.E.s for mechinical, electrical, and plumbing systens. Full engineering services to support your project.
WHY IT MATTERS
EFFICIENCY EXPERTISE INFORMS EVERYTHING WE BUILD
Most solar companies size systems based on roof space or budget. We size them based on your actual energy profile — load curves, demand peaks, operational patterns. That's what four decades of efficiency work taught us.
LOAD-BASED SIZING
We analyze your actual consumption data — not just roof area — to engineer the right system for your facility.
DEMAND PATTERN EXPERTISE
Decades of demand analysis means we design storage systems that target your actual peak windows.
BUILDING SYSTEMS KNOWLEDGE
We understand how your HVAC, process loads, and operations interact with solar production and storage dispatch.
