Maximum Energy Density for Utility-Scale Projects

When your utility-scale energy storage project demands the highest energy density, proven reliability, and industry-leading safety, the USCS-6300 delivers 6.261 MWh in a standard 20-foot container footprint—20% more energy than competing 5 MWh systems.

Empower IT brings you the most advanced containerized energy storage solution available.

Advanced Active Balancing Technology

The USCS-6300 leverages cutting-edge active balancing to maximize system performance, recovering 5–8% more usable capacity compared to traditional passive systems. By ensuring uniform cell charging and reducing internal stress, this technology extends battery cycle life by 20–30% while maintaining superior round-trip efficiency (86–88% RTE) at beginning-of-life. Unlike systems that degrade rapidly, this active architecture continually optimizes energy distribution as the system ages, ensuring high performance and capacity retention throughout its entire operational lifespan.

This is the engine that powers remote gold mines in Alaska, emergency facilities for major cities, 100MW utility plants in the Middle East, and critical infrastructure across six continents. Over 1,000 MW of installed Progen capacity worldwide proves what happens when American engineering meets real-world demands.

Intelligent Temperature Control: 3°C Precision

The USCS-6300’s centralized liquid cooling system utilizes multi-stage shunt control and parallel flow channels to achieve exceptional thermal precision, maintaining an industry-leading 3°C temperature variance across the entire 6.3 MWh container. This architecture ensures cell-level consistency within 2°C, employing a dynamic throttling control system to adjust cooling in real-time for optimal operating conditions. Additionally, integrated heating allows the system to maintain full performance in extreme environments, supporting operation down to -30°C without derating.
