History of Kamojang Geothermal Power Station, Indonesia
The Kamojang Geothermal Power Station is located in West Java, Indonesia, and is one of the oldest geothermal power plants in the world. The history of the Kamojang Geothermal Power Station dates back to the early 1900s when the Dutch colonial government began exploring the area for geothermal resources.
In 1926, a geologist named Reinier Gerhard Willem Van Bemmelen discovered the Kamojang geothermal field while conducting geological surveys in the region. The Kamojang geothermal field was found to have a high temperature and a large steam flow, making it an ideal location for a geothermal power plant.
The construction of the Kamojang Geothermal Power Station began in 1957, under the supervision of the Indonesian government. The power station was designed and built by a team of experts from the United States, Japan, and Germany, and was completed in 1961. The power station initially had a capacity of 30 megawatts (MW) and was the first geothermal power plant in Indonesia.
Over the years, the Kamojang Geothermal Power Station has undergone several upgrades and expansions. In 1978, the capacity of the power station was increased to 60 MW, and in 1982, it was further expanded to 140 MW. In 2002, the power station was upgraded again, increasing its capacity to 200 MW.
Today, the Kamojang Geothermal Power Station is owned and operated by PT Pertamina Geothermal Energy, a subsidiary of the state-owned oil and gas company PT Pertamina. The power station generates around 950 gigawatt-hours (GWh) of electricity per year and provides clean, renewable energy to the people of West Java and surrounding areas.

Kamojang Geothermal Power Station, Indonesia - Operator and Technology
Kamojang Geothermal Power Station is located in West Java, Indonesia. It is operated by PT Pertamina Geothermal Energy, a subsidiary of the state-owned oil and gas company PT Pertamina. The power station was commissioned in 1983 and has been in operation since then.
The Kamojang Geothermal Power Station uses binary cycle technology to generate electricity from geothermal resources. In a binary cycle power plant, geothermal water is pumped from underground reservoirs and passed through a heat exchanger, where it transfers its heat to a secondary fluid with a lower boiling point. The secondary fluid, usually a hydrocarbon or refrigerant, vaporizes and drives a turbine to generate electricity. The vapor is then condensed back into a liquid using a condenser, and the process is repeated.
The Kamojang power station has an installed capacity of 235 MW, making it one of the largest geothermal power plants in the world. It has 10 generating units, each with a capacity of 23.5 MW. The power station provides electricity to the Java-Bali power grid, which serves a population of over 140 million people. It is a key part of Indonesia's efforts to reduce its reliance on fossil fuels and promote renewable energy sources.
