Pertamina Persero PT is an Indonesian state-owned oil and gas company that has been operating in the country for more than 60 years. The company is responsible for the exploration, production, refining, and distribution of oil and gas products in Indonesia. However, in recent years, Pertamina has been expanding its operations to include renewable energy projects, particularly in the geothermal sector.

Geothermal energy is a type of renewable energy that is derived from the heat of the earth's core. It is a clean and sustainable source of energy that has the potential to replace fossil fuels in power generation. Indonesia is one of the world's largest producers of geothermal energy, with an estimated potential of 29 GW of geothermal power. Pertamina has recognized the potential of geothermal energy and has been investing in the development of geothermal projects in the country.

Pertamina's geothermal projects are focused on the exploration, development, and production of geothermal energy. The company has been working on several geothermal projects in different parts of Indonesia, including Java, Sumatra, Sulawesi, and Bali. The company's geothermal projects are aimed at reducing Indonesia's reliance on fossil fuels and promoting the use of clean and sustainable energy.

One of Pertamina's major geothermal projects is the Ulubelu Geothermal Power Plant in Lampung, Sumatra. The Ulubelu Geothermal Power Plant has a capacity of 220 MW and is one of the largest geothermal power plants in Indonesia. The project was developed by Pertamina in partnership with the Japan Bank for International Cooperation (JBIC) and the Asian Development Bank (ADB). The Ulubelu Geothermal Power Plant has been operational since 2012 and has been providing clean and sustainable energy to the people of Sumatra.

Pertamina has also been working on the development of geothermal projects in Java, the most populous island in Indonesia. The company's geothermal projects in Java include the Kamojang Geothermal Power Plant, the Darajat Geothermal Power Plant, and the Salak Geothermal Power Plant. The Kamojang Geothermal Power Plant has a capacity of 200 MW and has been operational since 1983. The Darajat Geothermal Power Plant has a capacity of 255 MW and has been operational since 1994. The Salak Geothermal Power Plant has a capacity of 377 MW and has been operational since 1994.

In addition to its geothermal projects in Sumatra and Java, Pertamina has also been working on the development of geothermal projects in other parts of Indonesia. The company's geothermal projects in Sulawesi include the Rantau Dedap Geothermal Power Plant and the Lahendong Geothermal Power Plant. The Rantau Dedap Geothermal Power Plant has a capacity of 55 MW and has been operational since 2018. The Lahendong Geothermal Power Plant has a capacity of 120 MW and has been operational since 2006.

Pertamina's geothermal projects in Bali include the Bedugul Geothermal Power Plant and the Bratan Geothermal Power Plant. The Bedugul Geothermal Power Plant has a capacity of 60 MW and has been operational since 2015. The Bratan Geothermal Power Plant has a capacity of 30 MW and has been operational since 2012.

Pertamina's geothermal projects have not only helped to reduce Indonesia's reliance on fossil fuels but have also created employment opportunities for the local communities. The development of geothermal projects requires a skilled workforce, and Pertamina has been providing training and employment opportunities to the local communities. The company has also been working with the local communities to ensure that the development of geothermal projects is done in a sustainable and responsible manner.

In conclusion, Pertamina Persero PT is an Indonesian state-owned oil and gas company that has been investing in renewable energy projects, particularly in the geothermal sector. The company's geothermal projects are aimed at reducing Indonesia's reliance on fossil fuels and promoting the use of clean and sustainable energy. Pertamina's geothermal projects have not only helped to reduce Indonesia's carbon footprint but have also created employment opportunities for the local communities. The company's commitment to sustainability and responsible development has made it a leader in the development of geothermal energy in Indonesia.
