Advanced manufacturing.Built in Alabama.
Callan Power plans to establish its corporate headquarters at the Atlas Complex in Marion, Alabama, through:
- Vertically Integrated Production
- In-house Testing
- Advanced Power-system Simulation
- State-of-the-art Automation
Callan Power intends to support greater production efficiency, consistent quality and more predictable delivery timelines.

Meeting a critical infrastructure need.
Transformers and other essential electrical components are fundamental to the reliable delivery of power.
Yet American power companies continue to face supply-chain disruptions, extended procurement timelines and limited domestic availability of critical equipment.
At the same time, grid modernization, industrial expansion, data-center development, electrification and rising electricity demand are placing additional pressure on the nation's power systems.
Callan Power is being built to help close that gap by expanding domestic manufacturing capacity and providing power companies with more dependable access to the equipment needed to support both current operations and future growth.
Planned Products
and Capabilities
Callan Power planned operations are expected to support a broad range of electrical infrastructure requirements.

Strengthening America's electrical supply chain.
Callan Power is focused on strengthening the domestic supply chain supporting the nation's power infrastructure. Its planned manufacturing capabilities are intended to help deliver:
- Greater domestic production of critical electrical equipment
- More reliable access to transformers and related power systems
- Reduced reliance on foreign supply chains
- Stronger production consistency and quality control
- Shorter and more predictable delivery timelines
- Increased grid resilience and infrastructure readiness
Callan Power's primary customers are expected to include electric power companies requiring dependable access to the equipment needed to maintain, expand, and modernize their systems.

Built on an established
power-management foundation.
Callan Power builds on more than 15 years of experience gained through Coldchain Technology Services LLC, a wholly owned subsidiary of Callan JMB.
Since 2009, Coldchain has managed fixed, hardened and mobile power-generation assets supporting healthcare organizations, government agencies and other critical operations during emergencies and planned continuity events.
Callan Power combines that operational foundation with a strategy to manufacture transformers and other critical electrical equipment domestically, extending Callan JMB's power capabilities from asset management and emergency preparedness into advanced manufacturing and broader electrical infrastructure.
Where power meets preparedness.
Reliable power is essential to healthcare, public safety, communications, manufacturing, commerce and community continuity.
Callan Power represents a natural extension of Callan JMB's experience in preparedness, logistics, infrastructure, and critical supply-chain management.
When power equipment is unavailable, delayed or dependent on vulnerable supply chains, the effects can extend far beyond the electrical grid.

By expanding domestic access to essential power-system equipment, Callan Power intends to help strengthen the systems responsible for keeping America's essential services operating.


Investing in Alabama's manufacturing.
Callan Power's planned operations are intended to contribute to Alabama's advanced-manufacturing economy while creating opportunities for technical training, workforce development and skilled employment.
Through collaboration with academic, public and private-sector organizations, the company aims to help develop the specialized workforce required to manufacture, operate and support the next generation of American electrical infrastructure.


Powering a more resilient future.
Callan Power is being built around a clear objective: manufacture more of America's critical electrical equipment in America.
By expanding domestic manufacturing, strengthening critical supply chains and helping power companies secure essential equipment, Callan Power intends to support a more reliable, resilient and prepared energy future.
