Engie Poções III: transfer cubicle for a 100% renewable substation
Alltec supplied Siemens Energy with the spare shunt reactor transfer cubicle bound for Engie’s Poções III in Bahia, Brazil, designed for safe transfer between the main and spare reactors while preserving protection selectivity.

In wind farm substations, reactive power management is critical to staying within the grid’s operating limits. Having transferable spare shunt reactors gives the system greater resilience to contingencies, maintenance, or rapid changes in loading.
The spare shunt reactor transfer cubicle supplied by Alltec to Siemens Energy, bound for Poções III in Bahia, Brazil, was designed for:
- safe transfer between main and spare reactors;
- preservation of protection selectivity;
- minimization of operational risks;
- compatibility with modern substation architectures, interconnecting Neoenergia’s Lot 2 project.
