The Energy Market Authority (EMA) said on Monday that it will carry out the next phase of studies to further assess the feasibility of harnessing geothermal energy for power generation, cooling, and heating.
This follows a two-year non-invasive geophysical survey which indicated that sizeable geothermal energy is present deep underground in Singapore, the authority said in a statement.
With next-generation geothermal technologies emerging, there may be potential for Singapore to tap on deep geothermal resources for its energy needs, it noted.
The non-invasive survey was conducted from 2024 to 2026 by a consortium of leading global consultants, including Chevron, Metatek Group, and Surbana Jurong.
The consortium found that Singapore has high-temperature geothermal resources at depths of several kilometers underground, which may be suitable for electricity generation.
The initial estimate of this geothermal resource potential is over sixty times the nation’s current annual electricity consumption of around 60 terawatt-hours (TWh), also known as the technical potential.
The consortium has also assessed that there are lower-temperature geothermal resources at shallower depths, which could potentially support industrial heating and cooling using heat pumps and absorption chillers.
Further studies will be needed to validate these estimates of Singapore’s geothermal technical potential and determine the amount of geothermal energy that can be feasibly extracted.
As an immediate next step, EMA has appointed a consortium formed by Surbana Jurong and GLJ Ltd to conduct a feasibility study on the potential deployment of next-generation geothermal plants in Singapore.
This follows a Request for Proposal launched in April 2026.
The study will cover safety considerations, technical viability, and the cost of geothermal energy production. The study is scheduled to commence by the end of 2026 and is estimated to take about 15 months.
“Geothermal energy is an indigenous source of clean energy that can provide constant power, and can potentially play an important role in our energy mix. If proven to be viable for electricity generation, Singapore’s geothermal energy resources will strengthen our energy resilience and support the decarbonization of the power sector,”
said Puah Kok Keong, Chief Executive of EMA.
Any decision to deploy geothermal will be taken after further technical and feasibility studies are completed and will depend on the progress of technologies for deep geothermal energy, said the statement.
