About Us

Our fully-managed clean microgrids are designed for fast, simple, and worry-free protection from extended grid outages.

High impact events such as extreme weather, cyber attacks, and other natural disasters have made power resiliency essential for many organizations. Business interruption from power outages creates risk due to worker and community safety, productivity and inventory losses, and property and reputation damage.

Enchanted Rock has reinvented outage protection to prevent these losses with fully managed clean microgrids, support services, and flexible pricing options designed for fast, simple, and worry-free resiliency.

We provide advanced, purpose-built, patented technology for resiliency microgrids, and our ongoing R&D efforts are focused on leveraging emerging technologies to support a greener grid.

Our Technology

Based on his experiences in nuclear energy engineering and systems management for the U.S. Navy, Enchanted Rock founder Thomas McAndrew created a cleaner, quieter, and far more reliable solution than traditional diesel generators.

Enchanted Rock’s unique Managed Power Resiliency solution brings patented technology, advanced microgrid designs, and integrated services together in a tightly orchestrated delivery model, fully managed by energy experts.


Our microgrids use readily available clean-burning natural gas or optional renewable natural gas that reduces local emissions by orders of magnitude and provide carbon free resiliency.

Quiet & Compact

With a standard package sound level of <68 dBa at 7 meters and power density matching diesel, our modular microgrids allow for multiple space-saving layout configurations.

Resilient & Reliable

Our microgrids provide quick start backup utility-grade generation in the event of an outage and provide grid support services to support integration of renewables. Our systems run often and loaded, ensuring constant equipment conditioning and testing for greater availability than traditional diesel backup.
