Peak shaving energy in gantry cranes

Epic Power will present a real-world application of its bi-directional DC/DC converters in gantry cranes, focusing on energy recovery and CO₂ emission reduction. These cranes, widely used in ports, operate on diesel gensets where braking energy is typically wasted as heat through resistor banks. By integrating supercapacitors and Epic's high-efficiency DC/DC converters into the crane's DC bus, this regenerative energy can be captured and reused in the next hoisting cycles.
Field data show that up to 70% of hoisting energy can be recovered, leading to annual fuel savings of over 32,000 liters and CO₂ reductions exceeding 8 tons per crane. Epic Power's modular converter technology ensures fast energy transfer and is optimized for short, high-power cycles — making it ideal for supercapacitor integration.
Of course, this peak shaving method can be used in numerous other industrial applications.

The session will include system architecture, sizing methodology, statistical energy profiling, and installation options. Attendees will gain insights into maximizing ROI through smart energy storage and conversion strategies — paving the way for greener, more efficient machine operations.
