State owned geothermal developer PT Geo Dipa Energi has launched a tender to upgrade the turbine at its Dieng geothermal plant in Indonesia. The project aims to improve efficiency and output from the existing geothermal facility, which is part of the country's push to expand renewable energy capacity. Details of the upgrade scope and capacity increase remain behind a paywall, but the tender signals ongoing investment in Indonesia's geothermal sector. Geothermal power is a key part of Indonesia's plan to decarbonize its grid and reduce reliance on fossil fuels. Upgrading existing turbines can often deliver more capacity at lower cost than building new plants. This tender could lead to higher generation from the Dieng field without additional drilling or land use. The outcome will be watched by investors tracking geothermal project finance in Southeast Asia.
