Having A Capacity Of 1,760 MW, The Largest Java-1 PLTGU In Southeast Asia Is Ready To Fully Operate

JAKARTA - The Java-1 Steam Gas Plant (PLTGU) with a capacity of 1,760 MW is ready to operate fully after passing a series of tests such as the plant reliability run & net dependent capacity test on Friday, March 29.

With the passing of this series of processes, Indonesia will officially have the largest integrated power plant in Southeast Asia which is equipped with a regasification system.

For information, the Java-1 PLTGU is managed by PT Jawa Satu Power (JSP) which is owned by a consortium between Pertamina New & Renewable Energy (Pertamina NRE) with 40 percent ownership, Marubeni 40 percent, and Sojitz 20 percent.

Pertamina NRE CEO John Anis expressed his extraordinary appreciation to all levels of JSP management and officers for their dedication and extraordinary hard work in completing this mega project.

"I congratulate and the highest appreciation to the management and JSP officers who show extraordinary patience, persistence and determination in facing challenges until they can finally realize this very crucial moment. Support from all parties is expected so that the Java-1 PLTGU can show operational excellence and can bring optimal benefits to Pertamina and the Republic of Indonesia," said John, Saturday, March 30.

He added that with all the unique installations, the Java-1 PLTGU could be one of the pillars of the energy transition that is the pride of Pertamina and Indonesia.

John classified the Java-1 PLTGU as a power plant that integrates floating storage and regasification units (FSRU) with a power plant unit with a capacity of 1,760 MW consisting of 2 generating units with each capacity of 880 MW. Unit 2 has been operating commercially since December 2023. This project connects the availability of gas supply in Papua with electricity needs in Java and Bali.

This project has a number of advantages, including being more efficient because it uses the latest generation of single-shaft combined gas turbine technology, so that the selling price of Electricity becomes competitive. In terms of operations, this generator has black-start capacity technology so that it can self-start itself when the grid is not available to import power for start-up power.

"By using a liquefied natural gas (LNG) fuel source, the resulting greenhouse gas emissions are lower than coal and fueled power plants," he continued.

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

The operation of the Java-1 PLTGU will be an important achievement point for Pertamina and at the same time add a portfolio for the use of clean energy in Pertamina's business. Natural gas plays a very strategic role in the energy transition period, which will support national energy security, and its low emissions place it in the category of clean energy.

"With the latest technology, the Java-1 PLTGU is projected to reduce carbon emissions by 3.3 million tco2e per year. A very significant figure for the contribution to net zero emissions. This is one of the important milestones created for the strategic synergy of SOEs, namely Pertamina and PLN, and the private sector of Marubeni and Sojitz and other parties who have a high commitment to jointly realize the transition to clean energy in Indonesia. Thank you for the best support from all parties," added John.
