Resilient Power Systems (RPS) offers utility grade Shore Power Systems (HVSC) that reduces demand billing charges for ports, ensures interoperability between 50Hz , 60Hz , and 400Hz systems, and can eliminate up to 6 transformers typically found in competing ship to shore solutions, which  dramatically reduces footprint and construction costs. For large reefer loads, backup power can be provided from diesel generators or battery storage, which is part of the RPS Energy  Management System that seamlessly optimizes loads and generation for up to 40% reduction in power bills.
