History of Wayang Windu Geothermal power plant- Indonesia
The history of the Wayang Windu geothermal field dates back to the early 1980s when exploration drilling was first conducted in the area. The geothermal field is located in the Bandung Regency of West Java, Indonesia.
In 1992, a consortium of companies comprising Unocal Corporation, Premier Oil, and Star Energy obtained the exploration rights to the Wayang Windu geothermal field. The consortium conducted further exploration activities, including drilling, to assess the geothermal resource potential of the area.
In 1994, the consortium signed a 30-year joint operation contract with the Indonesian government to develop the Wayang Windu geothermal field. Construction of the first power plant, Wayang Windu I, began in 1996 and was completed in 1999 with an installed capacity of 110 MW.
In 2000, the consortium sold its stake in the Wayang Windu project to Star Energy, a subsidiary of Salamander Energy, which subsequently became part of the Ophir Energy Group. Star Energy continued to operate the Wayang Windu I power plant and conducted further development of the geothermal field.
In 2005, Star Energy signed a joint operation contract extension with the Indonesian government to continue operating the Wayang Windu geothermal field for an additional 30 years. In 2009, the Wayang Windu II power plant, with an installed capacity of 117 MW, was completed and began operation.
In 2017, PT Pertamina Geothermal Energy, a subsidiary of Pertamina, acquired the Wayang Windu geothermal project from Ophir Energy. PT Pertamina Geothermal Energy is currently operating the Wayang Windu I and II power plants, which have a combined installed capacity of 227 MW. The Wayang Windu geothermal power plant continues to be an important contributor to Indonesia's energy mix, providing clean and sustainable electricity to the people of Indonesia.
Wayang Windu Geothermal power plant- Indonesia, Technology
The Wayang Windu Geothermal Power Plant utilizes binary cycle technology to generate electricity from the geothermal resource. Binary cycle technology is a type of geothermal power generation that uses a heat exchanger to transfer the heat from the geothermal fluid to a secondary fluid with a lower boiling point, which then vaporizes to drive a turbine.
The Wayang Windu geothermal field produces high-pressure, high-temperature geothermal fluid with temperatures up to 320°C and pressures up to 25 MPa. The geothermal fluid is extracted from the reservoir using production wells and is transported to the power plant through pipelines.
At the power plant, the geothermal fluid is fed into a binary cycle system, where it is used to vaporize a secondary fluid, which is typically an organic compound with a lower boiling point than water, such as isobutane or pentane. The vaporized secondary fluid drives a turbine, which in turn drives a generator to produce electricity.
After passing through the turbine, the vaporized secondary fluid is cooled and condensed back into a liquid, and then pumped back to the heat exchanger to be heated again by the geothermal fluid. The geothermal fluid is then re-injected back into the reservoir to maintain the pressure and sustainability of the geothermal resource.
The use of binary cycle technology offers several advantages for geothermal power generation, including high efficiency, low emissions, and minimal environmental impact. It also enables the generation of electricity from geothermal resources with lower temperatures and pressures, which may not be suitable for other types of geothermal power generation technologies.
Wayang Windu Geothermal power plant- Indonesia, environment impact
The Wayang Windu Geothermal Power Plant has a relatively low environmental impact compared to traditional fossil fuel power plants. Geothermal energy is a renewable energy source that emits low levels of greenhouse gases and air pollutants, making it a cleaner alternative to fossil fuels.
One of the main environmental impacts of geothermal power plants is the release of geothermal fluids, which can contain dissolved minerals and gases, such as hydrogen sulfide and carbon dioxide. However, the Wayang Windu Geothermal Power Plant uses a closed-loop system to extract and reinject geothermal fluids, minimizing the risk of environmental contamination and reducing the amount of fluids that need to be discharged.
The reinjection of geothermal fluids back into the reservoir also helps to maintain the pressure and sustainability of the geothermal resource. The Wayang Windu Geothermal Power Plant has implemented measures to monitor and mitigate any potential environmental impacts, including regular water quality testing and monitoring of air emissions.
Additionally, the construction and operation of the power plant have created job opportunities and provided economic benefits to the local community. The Wayang Windu Geothermal Power Plant has also contributed to the reduction of greenhouse gas emissions and the transition to a more sustainable energy system in Indonesia.
However, like all energy infrastructure, geothermal power plants can still have environmental impacts, particularly during the construction phase, which can disrupt ecosystems and habitats. Therefore, it is important to carefully assess and manage any potential environmental impacts associated with geothermal power plants to ensure their sustainability and minimize their impact on the environment.
