Critical Area in the hospital covers two (2) sections, which are;

OT Room and Recovery area
ICU/CICU/NICU

2. Existing HTS Policy

These area must be supplied by electrical power 100% of total uptime and also backup with the UPS (Uninterruptible Power Supply) System which includes lighting, and power point system.

3. New Policy

All critical area as mentioned above should have three (3) source of electrical power as below:

Normal supply – Normal electrical supply from TNB distribution
Generator System – Electrical supply from generator set if there is TNB power loss
UPS System – Electrical supply provided particularly to life-support systems as backup incase the generator breakdown or power irregularity.

The objective of the above is to ensure at any time, there will be at least 1 source of power supply at the critical areas.

HTS PROPOSAL

2. Distribution of power

The electrical power distribution is divided to:
i) UPS – 50%
ii) Generator – 30%
iii) TNB supply – 20%
Total 100%

3. Scenario

Typical ICU:

Unit of Power Point:
