What we do

Battery Storage.

Louth Callan is a trusted leader in delivering complex, large-scale battery storage solutions across the United States.

Built for Safety and Scale.

From grid-scale energy reserves that stabilize power networks to behind-the-meter systems that maximize efficiency and resilience, we bring deep technical expertise and proven project execution to every challenge.

Our team thrives on complexity—integrating cutting-edge storage technology with renewable generation to create smarter, more reliable energy systems.

Built to date

Over 800 MW of Utility-Scale BESS.

800MW

Utility-scale BESS across the East Coast and Midwest

Dispatchable, Not Just Installed.

As a trusted EPC provider for large-scale energy infrastructure, we specialize in the design, construction, and commissioning of advanced storage systems that improve grid stability, reduce curtailment, and enable true renewable energy dispatchability.

Our field-proven battery storage installations help utilities and developers store surplus solar and wind power, then discharge electricity during peak demand, grid outages, or periods of low generation—maximizing asset value and system reliability.

Performance, Safety, Operational Efficiency.

We integrate advanced energy management systems (EMS), fire suppression technologies, and robust civil and electrical designs into every BESS build—ensuring long-term reliability and compliance with evolving codes and utility interconnection standards.

Our in-house construction teams follow strict quality assurance and site safety protocols, managing every phase of BESS delivery—from site grading and enclosure installation to HVAC, inverters, and commissioning. We specialize in both grid-tied and microgrid applications, delivering scalable solutions for renewable integration, backup power, and load balancing.

Whether building stand-alone storage or hybrid solar-plus-storage systems, Louth Callan provides the construction expertise, technical execution, and project certainty needed to power the clean energy transition.
