History of Darajat Geothermal Power Station, Indonesia
The Darajat Geothermal Power Station is located in the Garut district of West Java, Indonesia. The power station is one of the oldest and largest geothermal power plants in Indonesia.
The development of the Darajat geothermal field began in the early 1980s by the Indonesian state-owned oil and gas company, Pertamina. Exploration drilling began in 1982 and commercial production started in 1994.
The first unit of the Darajat power plant, with a capacity of 55 MW, was commissioned in 1994. The second unit, with a capacity of 55 MW, was commissioned in 1999. In 2004, a third unit with a capacity of 55 MW was added to the power plant, bringing the total capacity to 165 MW.
In 2007, Pertamina Geothermal Energy (PGE), a subsidiary of Pertamina, took over the operation of the power plant. PGE expanded the power plant's capacity to 270 MW by adding a fourth unit with a capacity of 105 MW in 2016.
The Darajat power plant is known for its innovative technology and engineering solutions. The power plant utilizes a binary cycle technology, which is considered to be more efficient than other geothermal technologies. The binary cycle technology uses a heat exchanger to transfer heat from the geothermal fluid to a working fluid, which drives a turbine to produce electricity.
The Darajat power plant has been recognized as a sustainable energy project and has won several awards. In 2008, it won the "Asia Power Project of the Year" award at the Asian Power Awards. In 2011, it received the "Energy Globe Award" for its contribution to reducing CO2 emissions.

Development of Darajat Geothermal Power Station, Indonesia
The development of the Darajat Geothermal Power Station began in the early 1990s when Pertamina Geothermal Energy (PGE), a subsidiary of the Indonesian state-owned oil and gas company Pertamina, conducted exploration drilling in the Darajat geothermal field in West Java. The drilling confirmed the presence of a significant geothermal resource with the potential to generate electricity.
In 1994, PGE signed a power purchase agreement with the state-owned electricity company PLN to sell electricity generated from the Darajat power plant to the Java-Bali grid. In the same year, PGE began construction of the first phase of the power plant, which had a capacity of 110 MW.
The construction of the first phase was completed in 1999, and the power plant began commercial operation in the same year. In 2006, PGE completed the second phase of the power plant, adding another 110 MW of capacity and bringing the total capacity of the Darajat Geothermal Power Station to 220 MW.
Since its completion, the Darajat Geothermal Power Station has played an important role in Indonesia's renewable energy sector, providing a reliable source of electricity to the densely populated regions of Java and Bali. It has also helped to reduce Indonesia's dependence on fossil fuels and mitigate the impacts of climate change.

Darajat Geothermal Power Station, Indonesia - Operator and Technology
The Darajat Geothermal Power Station in Indonesia is operated by Pertamina Geothermal Energy, a subsidiary of Pertamina, which is the state-owned oil and gas company of Indonesia. Pertamina Geothermal Energy is responsible for the exploration, development, and operation of geothermal power plants in Indonesia, including the Darajat facility.
The technology used at the Darajat Geothermal Power Station is binary cycle. In a binary cycle power plant, hot water and steam from the geothermal reservoir are used to heat a working fluid, which has a lower boiling point than water, such as isobutane or pentane. The working fluid vaporizes and drives a turbine, which generates electricity. After passing through the turbine, the vaporized working fluid is condensed back into a liquid and the cycle begins again. Binary cycle technology is efficient, reliable, and has a relatively low environmental impact.
Darajat Geothermal Power Station, Indonesia - Financial and International Investment
There has been significant financial and international investment in the development and operation of the Darajat Geothermal Power Station in Indonesia.
The construction of the power plant was partly financed by a loan from the Japan Bank for International Cooperation (JBIC), a government-owned financial institution that provides development finance for projects in developing countries. The loan was used to finance the construction of the first two units of the power plant, which were commissioned in 1994.
In 2012, Pertamina Geothermal Energy secured a loan of $350 million from a consortium of international banks to finance the expansion of the Darajat Geothermal Power Station from 220 MW to 270 MW. The expansion involved the construction of two additional units at the power plant, which were commissioned in 2015.
