Gas supply to Bali
To meet total demand (2014 : 735 MW), Bali grid receives supply from Jawa grid through : 1. Submarine
Cable (4x100 MW)
2. On 2018,
additional Overhead TL 500 kV (400 MW)

Closing Remarks
1. Implementation of CNG/LNG technology is SIGNIFICANT as solution to replace current Power Plant’s fuel oil consumption.
2. In short term, LNG still be used as base loader, to replace fuel oil for all dual fired units. For long term, LNG will be assigned as peaking/medium units with supply swing rate (peak/off peak) vary from 40% - 100%.
3. Using MERIT ORDER analysis with least cost approach for electricity generation planning : “The more of LNG price the less volume it is required”.
