What Celec does
Celec is a Falkenberg, Sweden-based specialist in backup power (reservkraft) founded in 1947, providing custom-designed generator sets, container solutions (10–40 ft), stationary systems, and proprietary HMI-based control and monitoring platforms. The company assembles and integrates equipment sourced from roughly 100 motor and generator alternatives rather than manufacturing engines itself, with its differentiation rooted in custom engineering — load distribution, automated testing, parallel multi-generator operation, and Retrofit upgrades from legacy IPC+, DEIF, or PLC-based controls to modern architectures. Completed projects include a 2100kVA automated system for Gekås Ullared and MW-scale container solutions for power utilities.
