A proposed geothermal energy project in the Gunung Ungaran area of Central Java, designated as a National Strategic Project, has faced significant local opposition. Initial concerns centered on the potential for environmental damage and the disruption of vital drinking water sources for Semarang City.

In response to these concerns, PT PLN (Persero) clarified that the project is currently in the planning and feasibility study stage, rather than the construction or drilling phase. The company stated that its ongoing assessments include technical, safety, environmental, and social factors, as well as the preservation of cultural heritage. 

Legislators and residents have called for a re-evaluation of the project, citing specific risks to local biodiversity, such as the endangered Javan Hawk-eagle, and potential impacts on the historical Gedong Songo Temple complex.
