Wijaya Karya Persero Tbk PT, also known as Wika, is an Indonesian state-owned construction company that has been in operation since 1960. Over the years, the company has diversified its operations to include various sectors, including renewable energy. In recent years, Wika has been actively involved in the development of geothermal energy projects in Indonesia.

Geothermal energy is a form of renewable energy that is derived from the heat generated by the earth's core. Indonesia is one of the world's leading producers of geothermal energy, with vast geothermal resources spread across the country. The Indonesian government has set a target of generating 9,500 megawatts (MW) of geothermal energy by 2025, which presents a significant opportunity for companies like Wika.

Wika's involvement in geothermal energy dates back to the 1980s when the company was involved in the construction of the first geothermal power plant in Indonesia. Since then, Wika has been involved in the development of several geothermal projects in the country, including the 110 MW Lumut Balai geothermal power plant in South Sumatra.

In 2016, Wika signed a memorandum of understanding with PT Pertamina Geothermal Energy to develop a 110 MW geothermal power plant in Sulawesi. The project, which is expected to cost around $450 million, is part of the Indonesian government's plan to increase the country's geothermal energy capacity. Wika will be responsible for the engineering, procurement, and construction of the power plant, which is expected to be completed by 2021.

Wika's involvement in geothermal energy extends beyond the construction of power plants. The company is also involved in the exploration and development of geothermal resources. In 2017, Wika signed an agreement with PT Geo Dipa Energi, a state-owned geothermal energy company, to explore geothermal resources in the Dieng area of Central Java. The project is expected to cost around $4 million and will involve the drilling of several exploration wells to determine the potential of the geothermal resources in the area.

Wika's involvement in geothermal energy is part of the company's broader strategy to diversify its operations and increase its presence in the renewable energy sector. In addition to geothermal energy, Wika is also involved in the development of solar and hydroelectric power projects in Indonesia.

Wika's involvement in renewable energy is driven by the company's commitment to sustainable development and reducing Indonesia's dependence on fossil fuels. The company recognizes the importance of renewable energy in addressing the challenges of climate change and ensuring energy security for Indonesia's growing population.

Wika's commitment to sustainability is reflected in its corporate social responsibility (CSR) initiatives. The company has implemented several CSR programs aimed at improving the lives of communities living near its operations. These programs include the provision of clean water, education, and healthcare facilities.

In conclusion, Wijaya Karya Persero Tbk PT is a leading Indonesian construction company that has diversified its operations to include renewable energy. The company's involvement in geothermal energy is part of its broader strategy to increase its presence in the renewable energy sector and contribute to sustainable development in Indonesia. Wika's commitment to sustainability is reflected in its CSR initiatives, which aim to improve the lives of communities living near its operations. With Indonesia's target of generating 9,500 MW of geothermal energy by 2025, Wika is well-positioned to play a significant role in the country's renewable energy future.
