Singapore Explores Geothermal Energy for Power Needs
Singapore is assessing the viability of geothermal energy for electricity, heating, and cooling, as revealed by Minister Dr. Tan See Leng.
Geothermal Energy Assessment Announced
Singapore is embarking on a comprehensive evaluation of geothermal energy as a potential source for electricity generation, heating, and cooling. This announcement was made by the Minister for Energy, Trade and Industry, Dr. Tan See Leng, during the Singapore Energy Lecture at the Singapore International Energy Week 2026 (SIEW).
Preliminary Findings Support Potential
Last year’s non-invasive geophysical survey has yielded promising results, indicating the presence of high-temperature geothermal resources buried several kilometers underground. This could pave the way for electricity production. The technical assessment suggests that these geothermal sources could generate over 60 times the nation's annual electricity needs, which currently stands at approximately 60 terawatt-hours (TWh).
Broader Applications for Geothermal Resources
The Energy Market Authority of Singapore (EMA) released information post-lecture detailing that the survey identified lower-temperature geothermal resources located at shallower depths as well. These resources could be utilized for industrial heating and cooling through heat pumps and absorption chillers, expanding the versatility of geothermal energy in the region.
Despite the potential benefits, Dr. Tan warned that implementing next-generation geothermal power plants in Singapore poses challenges. The resources are located deep underground, and factors such as extraction costs, technical feasibility, and advancements in deep drilling technology will heavily influence the viability of harnessing geothermal power.
Urban Environment and Safety Considerations
Singapore's dense urban landscape also presents concerns regarding the feasible number of geothermal plants that can be established. Safety is another crucial aspect that needs to be prioritized by planners in this energy exploration.
Consortium Selected for Feasibility Study
Following a request for proposals launched in April, EMA has appointed a consortium comprising Surbana Jurong and the Canadian energy consulting firm GLJ to lead the next phase of the geothermal feasibility study. This extensive study is projected to last about 15 months and will analyze safety protocols, the technical viability of the resources, and the costs involved in geothermal energy production.
EMA's chief executive, Puah Kok Keong, emphasized the importance of geothermal energy as a locally-sourced, renewable energy alternative that could ensure a constant supply of power. If successful, it would enhance Singapore's energy resilience while aiding in the transition toward a decarbonized power sector.
Final decisions regarding the deployment of geothermal energy will be contingent upon the outcomes of detailed technical assessments and the advancements in deep geothermal technology.
Continuous Commitment to Energy Resilience
This initiative is just one of many energy-related developments highlighted at the SIEW. Dr. Tan reiterated the essential role of energy in Singapore’s future, stating, “We must ensure that our system resilience remains a foundation of confidence for our citizens.”
