VOInews, Jakarta: The Java-1 Steam Gas Power Plant (PLTGU) with a capacity of 1760 MW will soon start operating after a series of plant reliability run and net dependent capacity tests which were carried out at the end of March 2024.


PLTGU Jawa-1 is operated by PT Jawa Satu Power, which is a joint company owned by energy companies Pertamina NRE, Marubeni and Sojitz. Pertamina, through a press release, claims that PLTGU Jawa-1 is the largest integrated power plant in Southeast Asia which is equipped with a regasification system.


John Anis, CEO of Pertamina NRE, appreciated the management and officers of JSP for their loyalty and hard work in realizing this mega project.

"I congratulate and express my highest appreciation to JSP management and officers who showed extraordinary patience, persistence, and determination in facing challenges until finally being able to realize this very crucial moment," said John, as quoted on the Pertamina website, Saturday (3/30/2024).


"Support from all parties continues to be expected so that PLTGU Jawa-1 can demonstrate operational excellence and can bring optimal benefits to Pertamina and the Republic of Indonesia," he added.


John said, with all the uniqueness of its installation, PLTGU Jawa-1 could become one of the pillars of the energy transition that would be the pride of Pertamina and Indonesia.


Later, in distributing electricity to the community, PT Jawa Satu Power (JSP) will partner with National Electric Company (PLN).

PLTGU Jawa-1 is a power plant that integrates a floating storage and regasification unit (FSRU) with a power generating unit with a capacity of 1760 MW consisting of 2 generating units with a capacity of 880 MW each.


Previously, Unit 2 has been operating since December 2023. This project connects the availability of gas supplies in Papua with electricity needs on the islands of Java and Bali.


According to Pertamina, this project has a number of advantages, including being more efficient because it uses the latest generation of single shaft combined cycle gas turbine technology, so that electricity selling prices are competitive.


From an operational perspective, this plant has black start capability technology so that it can self-start up when imported power is not available on the grid for plant start-up purposes.


By using liquefied natural gas (LNG) as a fuel source, the resulting greenhouse gas emissions are said to be lower than coal or fuel-based power plants.

This is in line with efforts to reduce carbon emissions from the electricity sector. In addition, this plant uses closed loop cooling tower system technology which increases reliability in reducing the volume of sea water used to support plant operations.


Pertamina said the operation of PLTGU Jawa-1 would be an important milestone for the company as well as adding to its portfolio of clean energy utilization in its business.

According to Pertamina, natural gas plays a very strategic role in the energy transition period and will help support national energy security, and its low emissions place it in the clean energy category.

John said, with the latest technology, PLTGU Jawa-1 is projected to reduce carbon emissions by 3.3 million tco2e per year.

He said this figure was very significant for contributing to net zero emissions.

"This is one of the important milestones created by the strategic synergy of BUMN, namely Pertamina and PLN, and the private sector Marubeni and Sojitz and other parties who have a high commitment to jointly realizing the transition to clean energy in Indonesia. Thanks for the best support from all parties ," he explained.
