PGE Reduces Emissions and Conserves Energy Amidst Geothermal Expansion
JAKARTA, KOMPAS.com - PT Pertamina Geothermal Energy Tbk (PGE) (IDX: PGEO) is strengthening energy efficiency and emission reduction across all business lines amidst efforts to expand the utilization of low-carbon geothermal energy.
This step is being taken in line with the strengthening implementation of sustainable operations to support Indonesia’s Net Zero Emission (NZE) target and contribute to the Nationally Determined Contribution (NDC).
PGE Operations Director Andi Joko Nugroho said that the consistent implementation of sustainability practices is an important part of ensuring the development of reliable, efficient, and competitive geothermal resources.
“Geothermal development is not only focused on providing clean energy. PGE also ensures that all operations are carried out responsibly, efficiently, and provide sustainable benefits for the environment and the surrounding community,” said Andi Joko Nugroho, in a press release, quoted on Friday (15/5/2026).
“This commitment is carried out in line with PGE’s four pillars of sustainability, namely Nature, Zero Emission, People & Socioeconomics, and Transformation Catalyst,” said Andi.
Andi added that all of the company’s sustainability implementations are carried out transparently with reference to global reporting standards.
The company’s sustainability reporting has also undergone a verification process by an independent agency licensed AA1000 with assurance type 1 and type 2 level moderate qualifications.
The increase in efficiency is driven by various operational optimizations in a number of geothermal working areas (WKP), starting from debottlenecking production lines in the Ulubelu Area to optimizing the operation of vacuum pumps on the Gas Extraction System in all of PGE’s Geothermal Power Plants (PLTP) to reduce own use.
In addition, PGE also carried out modifications to the hand control valve in Lumut Balai to minimize steam discharged into the rock muffler.
The company also encourages various energy efficiency and emission reduction innovations, including the use of renewable energy for internal operational needs through the use of Solar Power Plants (PLTS) in operational facilities and offices.
This step is taken to optimize the use of electricity and geothermal steam so that it can contribute more to the national electricity system.
The ratio is a comparison between the total energy consumed by the company and the total geothermal electricity produced.
Meanwhile, the use of renewable energy in operations remains high at 94.36 percent.
From the emissions management side, PGE’s emission intensity was recorded at 41.12 g CO2e/kWh, which is still far below the EU Taxonomy and Indonesian Sustainable Finance Taxonomy threshold of 100 g CO2e/kWh.
At the same time, PGE’s geothermal operations capacity contributed to avoiding more than 4.29 million tons of CO2e emissions in 2025.
