Baseloader Load Follower Peaker

Typical drawback of piped natural gas in Indonesia : Limited opportunity for swing rate Still not integrated Gas reservoir decline earlier than what has been forecasted.

LNG VS CNG: VALUE CHAINS

Loading :Treat, liquefy, store Terminals: Jetty or regas offshore Ships : Sophisticated, efficient Receiving : Store, regasify

Loading :Dehydrate, compress Terminals: Jetty or buoy Ships : Simple – like bulk-carrier Receiving : Heat & decompress – utilize energy released

PIPELINES, CNG AND LNG SCENARIO

9 Stephen and Cano, 2004

CNG STORAGE NEAR PIPELINE RECEIVING FACILITY

National Electricity Company

GRESIK Gas Fired Power Plant :

Before : gas supply during off peak is surpressing operation of coal fired power plant nearby, and fuel oil still required during peaking time

GAS SUPLIER

CNG STORAGE SOLUTION

National Electricity Company

11

Problem : 1. Take or pay penalty with limited swing rate offered, make the operation

of gas fired power plants not optimum and tend to suppress the operation of coal fired power plants which assigned as baseloader.

2. Remote location with no gas resources, still need gas fired power plants to replace oil fueled power plants operated for intermediate and peaker units.

Solution : 1. Gas supply are sent at relatively flat rate, and diverted between power

plants and storage. 2. CNG Marine technology

IMPLEMENTATION CNG MARINE

National Electricity Company

12

1. No natural gas resources or allocation for the location 2. Marine transportation distance less than 500 NM 3. More economic than Mini LNG (ie. less complexity)

CNG MARINE WITH CONTAINERIZED CNG TUBE AND LCT BARGE

Small amount of existing gas supply in Batam island (4 BBTUD) is compressed and transported to Bintan island using truck and Landing Craft Tank Barge to suppy 6 MW Gas engine.

13

CNG MARINE WITH VESSEL

Gresik

Lombok

28 mmscf existing gas supply in Gresik is compressed and transported to Lombok using Vessel installed with CNG tubes, to supply a 90 MW Peaking Unit.

CLOSING REMARKS

1. Implementation of CNG/LNG technology is SIGNIFICANT as solution to replace current Power Plant’s fuel oil consumption..

2. CNG Storage will be installed to match fluctuative gas demand by load follower type gas power plant, when gas supplier unable to provide wider swing rate.

3. CNG Marine technology using barge feasible for short distance and very low gas demand (< 5mmscfd). Higher demand require CNG Vessel.

4. Benefit gained through implementation of CNG Storage : a. To avoid the use of fuel oil during peaking time lower fuel cost b. Cleaner power plant’s emission
