Southeast Asia’s Energy Future: Rising Demand, New Opportunities

In 2024, demand rose by more than 7% nearly twice the global average. If this pace continues, electricity demand could double again by 2050. Meeting such rapid growth in a secure and affordable way means diversifying energy supplies and reinforcing grid infrastructure is no longer optional, but essential.

The Power of Renewables

The region’s strongest advantage lies in its untapped renewable resources. Estimates suggest there is around 20 terawatts of potential in solar and wind more than fifty times today’s total installed capacity. Even harnessing a fraction of this could meet future demand while strengthening energy security.

What makes this even more compelling is economics: solar and wind have become some of the most cost-competitive options for new power generation. Expanding renewables reduces reliance on fuel imports, protects against global price swings, and helps countries move closer to their emissions targets.

Regional Policies and Commitments

Strategic frameworks like ASEAN Vision 2045 and the upcoming renewal of the ASEAN Plan of Action for Energy Cooperation highlight the priority given to clean energy. On top of that, 8 out of 10 ASEAN members have already announced net zero targets. Competitive auctions and direct power purchase agreements are also gaining ground, accelerating renewable adoption.

These developments promise not only more reliable energy but also cleaner cities, reduced costs, and stronger resilience across the region.

Challenges That Can Be Managed

Integrating higher shares of variable renewables will bring technical challenges such as fluctuations in output and system flexibility. Yet, the report stresses that these challenges are solvable with proven, low-cost measures:

• Increasing flexibility in existing power plants
• Using advanced forecasting methods
• Updating and enforcing modern grid codes
• Expanding demand response through smart appliances, EV charging, and storage

All of these solutions are affordable and can be rolled out without large scale system overhauls.

A Global Turning Point

The IEA’s decision to open its first office outside Paris in Singapore the IEA Regional Cooperation Centre underlines Southeast Asia’s central role in the global energy transition. The Centre provides direct support for renewable integration, grid modernization, and long term energy strategies tailored to the region’s needs.
