Singapore finds geothermal potential exceeding its yearly power use by over 60 times

Singapore’s Energy Market Authority announced that a recent non-invasive geophysical survey has revealed high-temperature geothermal reservoirs deep beneath the city-state, with a theoretical output exceeding 60 times its current annual electricity consumption of about 60 TWh. Conducted from 2024 to 2026, the survey employed two non-intrusive techniques to build three-dimensional geological and heat-resource models, with data gathered by Metatek Group and modelled by Chevron.

In addition to deep, high-temperature sources suitable for power generation, the study identified shallower, lower-temperature heat that could support industrial heating and cooling. EMA plans a second phase of feasibility studies, appointing a Surbana Jurong and GLJ Ltd consortium to examine safety, technical viability and cost, with work slated to begin by year-end and last roughly 15 months. Ministers emphasized that urban density and drilling technology will shape how many geothermal plants could be deployed, and that the option remains under serious consideration.
