BBG begins transporting gas from East Java to West Java via the Cisem pipeline
Jakarta (ANTARA) – Natural gas distribution company 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, to meet customer demand in the region.
BBG President Director Andi Rachman said the transportation was carried out under a gas transportation agreement with PT Pertamina Gas (Pertagas), with daily capacity of 3 million standard cubic feet per day (MMSCFD) reserved.
“The agreed capacity supports BBG’s use of interconnected transmission networks to meet its customers’ energy needs,” Andi said in an official statement received in Jakarta on Thursday.
With this flow, BBG has become one of the gas shippers using the Cisem network to connect domestic supplies from East Java with demand in West Java.
The company said the gas flow in early September also followed a request from the Ministry of Energy and Mineral Resources (ESDM) to support further testing on the Batang–Kandang Haur Timur (KHT) section, also known as Cisem II.
On 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.
The request also covered internal pipeline cleaning (cleaning pigging) on the Batang–KHT section and preparations for subsequent gas deliveries through the interconnected transmission network.
BBG began flowing gas on 4 September 2026. The company said the further testing of the gas measurement system was completed on 6 September 2026.
Cisem II is a natural gas transmission infrastructure project around 242 kilometres long, connecting Batang in Central Java with Kandang Haur Timur in West Java.
According to the Ministry of Energy and Mineral Resources, Cisem II was declared ready for full operation following commissioning and integration of the gas transmission system at Kandang Haur Timur on 6 June 2026.
In April 2026, the government, through the LEMIGAS Centre for Oil and Gas Testing, appointed Pertagas as operator of Cisem II. Pertagas had already operated Cisem I, which connects Semarang and Batang.
The connection between the two sections forms part of the integration of Java’s natural gas transmission network, enabling supplies from East Java to be delivered to energy demand centres in Central and West Java.
Pertagas said on 8 July 2026 that integrating Cisem II could help address natural gas supply constraints in West Java by making use of gas from East Java.
BBG said using the Cisem network broadens access to domestic gas supplies and provides greater transportation flexibility to serve industrial and commercial customers.
The company said it would prioritise meeting the needs of existing customers using the transportation capacity agreed with Pertagas, in line with the government’s efforts to increase domestic use of natural gas.
