1. Geothermal Potential 60
Times Our Annual Power Needs
At the
Singapore Energy Lecture on 26 October 2026, Minister Dr Tan See Leng shared
that a geophysical survey estimated Singapore’s geothermal technical potential
at more than 60 times our annual electricity consumption of around 60 TWh.
High-temperature resources were found several kilometres underground. EMA has
appointed a Surbana Jurong and GLJ consortium to run a feasibility study of
about 15 months from end-2026, covering safety, technical viability and cost.
Folks, we
grew up being told Singapore has no natural resources except our people. As
recently as 2019, the official line was that we have no usable geothermal at
all. This is jaw-dropping news.
2. Why It Could Be a Game
Changer
About 95% of
our electricity comes from imported natural gas. Solar is intermittent and
land-hungry. Geothermal, by contrast, is home-grown, clean and runs 24/7, the
energy version of a reliable dividend stock that pays every month without fail.
My last post only talked about nuclear as our energy “fifth tap”. Geothermal
now gives us a possible sixth. Together, they could move Singapore from
near-total import dependence towards real energy self-sufficiency.
A dose of
realism though. Technical potential is not the same as economically
recoverable. Deep drilling is costly, safety comes first in a dense city, and
no decision to deploy has been made yet. Think of this as a promising
exploration result, not a producing oil field. Still, far better than a dry
well.
3. Singaporeans, Stop
Quarrelling Online
To my fellow
Singaporeans: please stop arguing with Indonesian government supporters online
over the haze and gas cut. These debates are impossible to win and meaningless.
Nobody changes their mind because of a clever comment, and the noise only feeds
politicians who like painting Singapore as the villain. Ordinary Indonesians
suffer from the haze as much as we do. Talk is of no use, and keyboard wars do
not keep the lights on.
4. Lay Low and Build
Singapore
beat the water threats not by shouting, but by quietly building NEWater and
desalination plants. Energy should follow the same playbook. Lay low and build
up our nuclear and geothermal capabilities for self-sufficiency. The groundwork
is already happening: five new power plants will come online between 2026 and
2031, and Sembcorp will get conditional approval to import up to 1.3 GW of
renewable electricity via Peninsular Malaysia. Every new source is one less
lever anyone can pull on us.
5. But Not Total Silence
Laying low
does not mean rolling over. The proper channel is our PM and ministers. PM
Lawrence Wong has said Singapore expects all parties to honour their
commitments, and Gas Supply will check for any breach of contract and pursue
remedies if needed. Indonesia insists the cuts are within contract limits, but
coming right after threats against countries that “disrespect” it, the spirit
of a reliable partnership has clearly been dented. Our leaders must respond
firmly through proper channels. Total silence would signal such moves are
cost-free and invite more gas cuts.
6. What This Means for
Investors
Energy
security is now a firm national priority, which usually means sustained capital
spending. Sembcorp Industries and Keppel Ltd sit right in this theme through
power generation, regional imports and low-carbon projects. Geothermal itself
is a long-dated story with no quick trade, but a Singapore that generates more
of its own power is a safer home for capital, businesses, data centres and our
REITs. As always, this is my personal view, not financial advice.
7. Parting Thoughts
Overall, I
am happy. Nuclear plus geothermal could be a real game changer for a country
long thought to have no natural resources. Let our leaders handle the
diplomacy and let our engineers do the quiet work,
Ok folks,
that’s all from me today. Have a great week ahead!
