Refrigeration Facilities
Engineering solutions for temperature-critical cold-chain facilities
Cold-storage facilities operate some of the most electricity-intensive systems in logistics infrastructure. Refrigeration compressors, defrost cycles and strict temperature requirements create complex load patterns and high peak demand.
K24Energy designs PV, BESS and EMS architectures that stabilise refrigeration loads, reduce electricity costs and support continuous temperature-controlled operations.
Our engineering integrates energy infrastructure with refrigeration systems to optimise energy performance without compromising product safety.

Why are cold-storage facilities energy-intensive?
Cold-storage facilities require continuous refrigeration to maintain product temperature. Compressors and cooling systems operate almost constantly, leading to high electricity consumption.
How can BESS support refrigeration systems?
Battery storage smooths peak demand from compressor start-ups and stabilises facility electricity demand, improving energy efficiency.
Can PV be used in cold-storage facilities?
Yes. Many cold-storage facilities have large roof surfaces suitable for PV systems, which can supply daytime cooling demand.
What role does EMS play in refrigeration facilities?
An EMS coordinates compressor, defrost cycles and battery storage to optimise electricity consumption while maintaining temperature stability.
Can cold-storage facilities participate in flexibility markets?
Facilities with BESS and EMS control systems may participate in demand response or Virtual Power Plant programs depending on market regulations.
What documentation is required before project implementation?
Cold-storage energy projects typically require energy modelling, system design, financial analysis and FEED engineering documentation.
