The document summarizes the planned generator arrangements and power outages during maintenance from January 7-21. Key points: 1. The plant and CMC office may experience 10-20 minute power outages twice daily as generators transition. This could impact critical equipment like C851 and P903 in the plant as well as IT servers. 2. DIC and IAM have been informed and have their own backup power, but IAM needs notice ISM will not provide power during this period. 3. Details are provided on generator transition times, procedures, cabling, fuel storage and responsibilities of operators to coordinate the transitions and monitor fuel consumption.

1. GENSET ARRANGEMENT DURING TA2021

2. Area/Equipment Impacted From Power Outage
1. Plant (Production)
2. CMC Office
3. DIC
4. IAM

3. 1. Plant (Production)
Equipment that critical:
-C851
-P903
The issue:
-A power supply interruption may occur (roughly 10 mins) during the transition of power from 1 generator to another.
-Time for genset transition is 7am and 7pm everyday for 14 days.
Concern:
-10 minutes is acceptable for C851 not running?
-10 minutes is acceptable for P903 not running? Shipping/circulation

4. 2. CMC Office
Equipment that critical:
IT Server
The issue:
-A power supply interruption may occur (roughly 10 - 20 mins) during the transition of power from 1 generator to another.
-1 genset can run maximum 12 Hours.
-Time for genset transition is 6am and 6pm everyday for 14 days.
Concern:
IT server will have no power supply 2 times a day for 14 days. (During not office hour)

5. DIC & IAM
DIC
-Already informed and they will have their on power supply
IAM
-Need to inform IAM that ISM not supply power supply during this 14 days of power cut

6. Genset Arrangement details
Details on:
1.Time of genset transition
-Substation 2 and substation 4
2. Procedure of genset transition
3. Cable for 2 area
-Cable between 2 (625kVA genset) to change over switch
-Cable between 2 (250kVA genset) and also from change over switch to the ACB panel
4. Tank to diesel storage
(Daily usage estimate 3000liter)
5.Job scope of the genset operator
Top up diesel
Switching – (Also need coordinate with chargeman)
6.Checklist to check diesel consumption
