Located next to container terminals, TP-Singapore DP comprises of two 5-storey blocks offering 60,000m² of prime logistics space. This facility had an existing power system with 6.6kV feed from port. PowerQ’s role for Phase 1 was to evaluate current power demand and forecast future demands.
PowerQ evaluated multiple options for upgrade and prepared a detailed feasibility report.
Phase 2 of the work involved engineering design, liaising with utility distribution company, tendering and project management services. The system was upgraded to; 22kV feeders supplied from a new source, a new 22kV substation was built, an old 6.6 KV transformer was replaced with 4×2.5 MVA ONAN transformers, 22 kV ABB switchgear and a replacement of 4000 amp low voltage bus duct. Other than that, as part of the upgrade, the facility was installed with emergency diesel Genset to supply emergency loads.
The challenge was to create a parallel power system and transfer the power from 6.6 kV to 22kV during weekend/overnight shutdown to minimize the affect on ongoing work. The engineering contractor, Shinryo took care of all safety precautions to avoid disruption during power transfer by incorporating contingency measures such as portable gensets. The project involved as well an upgrade and alteration of other systems such as fire protection and ventilation system.
