Geothermal power is an important source of renewable energy in Indonesia, and the government has set ambitious targets for the development of geothermal energy in the country.

History of Salak Geothermal power plant- Indonesia

The Salak Geothermal Power Plant has a relatively long history, dating back to the 1970s when the Indonesian government began exploring the country’s geothermal resources as a potential source of electricity.

In the early 1980s, a consortium of companies including Unocal and Chevron began developing the Salak geothermal field. The first exploratory well was drilled in 1983, and by the mid-1980s, the consortium had drilled several more wells and completed a pilot plant.

In 1987, the Indonesian government awarded Pertamina, the state-owned oil and gas company, a contract to develop the Salak geothermal field. Pertamina formed a subsidiary, Pertamina Geothermal Energy, to manage the project.

Construction of the Salak Geothermal Power Plant began in the early 1990s, and the plant began commercial operation in 1994. At the time, it was one of the largest geothermal power plants in the world, with an installed capacity of 270 MW. In the years since, additional units have been added to the plant, bringing its total installed capacity to 377 MW.

Today, the Salak Geothermal Power Plant is a key component of Indonesia’s energy mix, providing a significant amount of electricity to the Java-Bali power grid. The plant is also involved in research and development activities related to geothermal energy, and it has helped to establish Indonesia as a global leader in geothermal energy development.
