BBG Begins Transporting East Java Gas to West Java via the Cisem Pipeline
JAKARTA – PT Bayu Buana Gemilang (BBG) began transporting natural gas from East Java to West Java through the Cirebon–Semarang (Cisem) pipeline network on 4 September 2026. The flow, at a capacity of 3 million standard cubic feet per day (MMSCFD), uses connected gas infrastructure to meet the needs of BBG’s customers in West Java.
The gas is transported under a Gas Transportation Agreement between BBG and PT Pertamina Gas (Pertagas). With this operation, BBG has become one of the shippers transporting gas from East Java to West Java through the Cisem network.
BBG President Director Andi Rachman said the use of the Cisem network expands the interregional connectivity of natural gas distribution. The infrastructure allows the company to access domestic supplies from other regions to meet customer demand.
“The start of gas transportation through the Cisem pipeline is an important step in expanding the connectivity of the natural gas network on Java. BBG is committed to using this infrastructure to support the transportation of gas from East Java to West Java and ensure the energy needs of existing customers are met,” Andi said in a press release on Thursday (5 November 2026).
The gas flow also follows a request from the Ministry of Energy and Mineral Resources (ESDM) for BBG to support commissioning of the Batang–Kandang Haur Timur (KHT) transmission pipeline section, also known as Cisem II. In a letter dated 3 September 2026, the Directorate of Oil and Gas Infrastructure Planning and Development asked BBG to provide gas for further dynamic testing of the gas measurement system at KHT, cleaning and pigging of the Batang–KHT section, and subsequent gas transportation.
BBG began flowing gas on 4 September 2026 to support testing and preparations for the infrastructure’s operation. Commissioning of the gas measurement system was completed on 6 September 2026.
Cisem II is about 242 kilometres long and connects Batang in Central Java with KHT in West Java. The route links natural gas transmission infrastructure on Java, helping facilitate transportation between supply sources and centres of energy demand.
Andi said connections between pipelines provide greater flexibility in transporting domestic gas. Collaboration among the government, pipeline operators and shippers is needed to ensure that existing infrastructure is used effectively.
“Integrating the gas transmission network requires cooperation between the government, pipeline operators and businesses. Available infrastructure must be matched by the use of transportation capacity so that domestic gas supplies can reach customers more efficiently,” Andi said.
Through its cooperation with Pertagas, BBG is currently using daily transportation capacity of 3 MMSCFD to meet the needs of its existing customers in West Java. The gas flow also supports greater use of domestic natural gas and stronger national energy connectivity.
