Medium voltage electrification: decarbonising the industrial sector implementation
Decarbonising process heat is one of the biggest challenges facing refineries, petrochemical plants, and other energy-intensive industries. Traditionally dependent on gas- and oil-fired systems, operators must reduce emissions while maintaining the reliability, safety, and performance their processes demand.
This white paper explores how medium voltage electric process heating can provide a practical and scalable pathway to industrial decarbonisation. By operating at higher voltages, these systems reduce current requirements, enabling smaller cables, lighter switchgear, and simpler installations. They can also eliminate the need for step-down transformers, helping reduce electrical losses and equipment footprint. The paper examines how medium voltage technology can scale electric heaters into the multi-megawatt range required for large refinery and chemical applications.
It also addresses the critical engineering considerations behind successful implementation, including insulation design, partial discharge, arc-flash protection, thermal management, control, and compliance with evolving industry standards. Using Watlow’s POWERSAFE™ system as an example, the paper shows how integrated heater and control technologies can combine high efficiency, modularity, safety, and reliability for demanding industrial applications. It also highlights opportunities including crude preheating, amine regeneration, and steam generation.
