Mother of Mercy Hospital - Mission-Critical Power Redundancy

Mother of Mercy Hospital ā€¢ Gidel, Nuba Mountains

The Challenge

Hospital in remote South Sudan required 99.99% uptime for operating theaters, ICU, and life support systems. Existing generator had 12-second transfer time causing critical equipment shutdowns during grid failures. Remote location demanded exceptional reliability.

Our Solution

Installed redundant 1000kVA + 750kVA Cummins generators with N+1 configuration. DeepSea DSE8610 MKII synchronization control with load-sharing. 10-second parallel operation before mains disconnect. Added 200kVA UPS for seamless transfer (<4ms switchover).

Kenya Seed Company - Cold Storage Reliability

Kenya Seed Company ā€¢ Kitale, Trans Nzoia County

The Challenge

Seed cold storage requires constant 4Ā°CĀ±1Ā°C. Grid power in Kitale unstable (20-30 outages/month). Previous generator took 15 seconds to start, causing temperature spikes to 8Ā°C, degrading seed viability. Lost KES 8M in spoiled seeds in 2023.

Our Solution

Installed 200kVA Perkins generator with instant-start capability (<2 seconds). Added 50kVA UPS for seamless cold storage transfer. Implemented EmersonEIMS remote monitoring with SMS alerts for temp deviations. Preventive maintenance contract with 4-hour response SLA.
