EMA to study geothermal power feasibility after survey finds deep resources

Surbana Jurong and GLJ Ltd are the consortium appointed to lead the assessment.

The Energy Market Authority (EMA) will conduct further studies to assess the feasibility of geothermal power generation after a survey detected geothermal energy several kilometres underground in Singapore.

EMA has appointed a consortium comprising Surbana Jurong and GLJ Ltd to assess the feasibility of deploying next-generation geothermal plants, including their safety, technical viability, and production costs.

The study is expected to begin by the end of 2026 and take about 15 months.

“If proven to be viable for electricity generation, Singapore’s geothermal energy resources will strengthen our energy resilience and support the decarbonisation of the power sector,” said Puah Kok Keong, EMA CEO.

The two-year non-invasive geophysical survey, conducted by a consortium of global consultants starting from 2024, identified geothermal resources that could be suitable for electricity generation.

EMA estimated the resources’ technical potential at more than 60 times Singapore’s annual electricity consumption of about 60 terawatt-hours.

The consortium has also found lower-temperature geothermal resources at shallower depths, which could potentially support industrial heating and cooling using heat pumps and absorption chillers.

Any deployment decision will depend on the findings of further technical and feasibility studies, as well as advances in deep geothermal technology, EMA added.

A NOTE FROM SINGAPORE BUSINESS REVIEW

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
