Keeping the lights on is becoming a more complicated job. Rising electricity demand, the growth of AI, geopolitical uncertainty and the push towards lower-carbon energy are forcing countries to rethink how their energy systems are built.

In this SIEWCast, Lynlee Foo speaks with Puah Kok Keong, Chief Executive of Singapore’s Energy Market Authority, about balancing energy security, economic competitiveness and sustainability, why greater regional connectivity matters for Southeast Asia, and how Singapore is preparing for its energy future - from solar and electricity imports to emerging technologies such as geothermal and nuclear energy.

The conversation reflects the theme of Singapore International Energy Week 2026 — Connecting Energy Systems, Powering Tomorrow.
