Modular Power Systems Overview
Factory-Built Power Infrastructure for Faster Deployment

MCG engineers, manufactures, integrates, tests, and provides lifecycle support for modular power systems in the United States, delivering prefabricated power infrastructure ready for site installation. Our U.S. manufacturing facilities bring complex electrical and mechanical work into a controlled factory environment to improve quality, reduce coordination risk, and support phased expansion.

The MCG Modular Power Center of Excellence delivers configurable systems for electrical distribution, power control, and phased infrastructure deployment.

Electrical Equipment
E-Houses
Prefabricated buildings house low- and medium-voltage switchgear, protection, controls, and HVAC, replacing site-built electrical rooms.
Electrical Equipment
MCPU
Mission Critical Power Units deliver 3 MW of integrated power on skids, providing a repeatable power distribution backbone for phased expansion.
Solar Cells
Microgrids
MicroGENIUS systems coordinate generation, distribution, and intelligent controls to support resilient on-site power.
Modular Power
GENIUS Modular Data Centers
Modular platforms support repeatable data center deployment and phased capacity expansion.
Electrical Equipment
Power Systems for Modular Data Centers
Integrated electrical equipment, distribution, and controls provide the powertrain within a modular data center.
Custom Power Skids and Distribution Centers
Engineered-to-order assemblies package electrical equipment and controls around project-specific layouts and performance requirements, replacing field assembly of individual components.

E-Houses

MCG designs and manufactures prefabricated electrical houses, or E-Houses, that bring low- and medium-voltage power distribution equipment together in a factory-tested building. Each E-House is engineered to meet project specifications, equipment layouts, site conditions, and local requirements.

Factory Integration and Testing

Factory acceptance testing validates equipment, controls, and integrated system operation before shipment. Testing identifies issues before installation, reduces field rework, and supports a more predictable deployment.

Integrated Electrical Equipment

E-Houses accommodate low- and medium-voltage switchgear, motor control centers, drives, protection and control systems, HVAC, and auxiliary systems. Electrical and mechanical systems are assembled and integrated before delivery to simplify onsite installation.

Mission Critical Power Units

MCPU platforms provide a compact, scalable approach to mission critical power distribution. Pre-engineered building blocks can integrate UPS systems, batteries, bypass equipment, switchboards, controls, cooling, and fire protection based on the application.
