The IEA is urging Southeast Asian countries to share more electricity and diversify supplies as demand grows, according to a report covered by VnExpress. It forecasts average annual regional energy-demand growth of 5.4% through 2030, driven by cooling, data centres and industry. Limited reserves and differences between national market systems complicate responses to supply disruptions. The recommendations also include greater efficiency and use of domestic resources. The growth rate is a forecast, and the proposals do not mean that a unified regional electricity market is already operating.
