Operations & Maintenance Services
Performance you can count on. Uptime you don’t have to think about.
At Enchanted Rock, our job isn’t finished once a microgrid is installed—it’s just getting started. Our fully integrated Operations & Maintenance (O&M) services are designed to deliver peace of mind, ensuring your critical power assets perform exactly as expected, exactly when needed.
Unlike typical O&M providers, we don’t just service equipment—we operate entire systems with accountability, precision, and reliability. Our 24/7 ERock Microgrid Control Center is at the heart of it all, keeping eyes on your assets and our fleet nationwide, through a hub-andspoke model that delivers fast, expert support—whenever and wherever it’s needed.

Our Houston-based microgrid control center serves as the central “hub,” monitoring microgrid operations 24/7 and coordinating dispatch to our regional field teams—the
“spokes.” This structure enables faster response times, better resource utilization, and consistent service delivery across the U.S.
Proactive Maintenance, Not Just Reactive Fixes
Predictive analytics and system health tools help us stay ahead of maintenance needs. By identifying patterns and trends, we can often prevent issues before they interrupt your operations.
Fully-Staffed Field Service Teams
With boots on the ground across the country, our technicians are strategically located to respond quickly and efficiently. Preventive maintenance, inspections, and service calls are all coordinated seamlessly through our control center. We need to make sure in this we mention that they are our full-time team members – not contractors, not outsourced, not dealers or distributors.
End-to-End Asset Management
We manage your assets so you don’t have to—tracking performance, logging historical data, managing warranties, and ensuring compliance with all applicable regulations and safety standards.
Built for Standardization and Simplicity
We design systems for serviceability. All our sites use standardized equipment and processes, so technicians are trained on a single platform and can be dispatched to any site with confidence. Maintenance can be performed by a single technician—no special tools, no complexity, no guesswork.
Proactive, Predictive Maintenance
Preventative service schedules are rigorously followed, backed by real-time monitoring and predictive analytics. Our “run often, run loaded” philosophy ensures equipment is always in a ready state—not just for emergencies.
Streamlined Spare Parts and Logistics
Standardization also means simpler inventory management. Our teams carry what they need—minimizing downtime and maximizing efficiency.
Fleet-Wide Insights Drive Continuous Improvement
With one of the largest fleets of natural gas microgrids in the nation, we leverage aggregated operational data to refine processes, update maintenance practices, and push performance higher across the board.
Proven Reliability in Extreme Events
Our O&M performance has been tested and proven during hurricanes, winter storms, and widespread outages. When the grid fails, our systems—and our team— stay online. With a combined fleet reliability of 99.999%, our O&M program is designed not just to support your operations—but to ensure you don’t have to think
about them.
