About us

Greenfield Energy is a Wilmington-based generator company specializing in custom backup power solutions for residential, commercial, and agricultural properties across North Carolina and South Carolina. Unlike most dealers who only install one brand, we’re machine specialists with deep technical expertise and a focus on finding the right solution for your specific needs.

We provide generator installation, maintenance, and energy consulting, and proudly assemble our own line of HERO Generators—featuring water- and radiator-cooled diesel models designed for long-term reliability. Whether you're dealing with coastal corrosion, rural grid instability, or high-demand commercial loads, our expert-driven systems are built to perform where others fail.

With over 50 years of combined experience, our team doesn't just sell what we have. We deliver what you actually need.
