The JSA aims to draw on the complementary strengths of PGE, the largest geothermal company in Indonesia and Chevron, a multinational energy corporation committed to providing affordable, reliable, and ever-cleaner energy. Chevron is confident that its expertise and technologies in geothermal exploration, subsurface studies, project development, and operational excellence combined with PGE’s extensive geothermal operations will bring value and benefit to the wider community through the provision of reliable and affordable renewable energy.  

President Director PT Pertamina Geothermal Energy Tbk. Julfi Hadi enthusiastically welcomed the Joint Study Agreement collaboration between PGE and Chevron, “With its abundant renewable resources and favorable geographical location, Indonesia has all the ingredients necessary to become a prominent source of green hydrogen and ammonia. Realizing this potential, PGE is synergizing with Chevron in hopes it can have a broad positive impact on society, especially in the Southern Sumatra region. This collaboration is also our first step towards becoming a 1 GW company within the next two years.”

Chevron Indonesia Country Manager, Wahyu Budiarto, stated, “We have a long history of working in Indonesia and with Pertamina. Indonesia has been an important part of our company’s portfolio for many years. We look forward to leveraging Chevron’s expertise and novel technologies in geothermal to explore Indonesia’s renewable energy resources with PGE.”

This JSA is the fourth agreement to come out of the initial collaboration between Chevron and Pertamina announced in Washington, D.C., in May 2022 to explore potential lower carbon business opportunities in Indonesia. The first, announced at the B20 in Bali in November 2022 between Chevron New Energies, Pertamina Power Indonesia and Keppel Infrastructure, is aimed at exploring the development of selected green hydrogen and green ammonia projects, using renewable energy in South Sumatera, Indonesia. The second JSA was signed in Houston, Texas on March 6, 2023, to examine the feasibility of carbon capture storage and carbon capture utilization and storage (CCS/CCUS) in East Kalimantan, Indonesia. The third, PGE and a Chevron affiliate in Indonesia, entered into a consortium agreement to participate and then won in a tender of Way Ratai geothermal working area in Lampung, Indonesia.
