Singapore is accelerating its energy transition by pursuing large-scale cross-border renewable power import and regional grid interconnection. Targeting up to 6 GW of low-carbon power import by 2035—equivalent to nearly half of its projected electricity demand—Singapore is poised to transform from a gas-dominated urban power system into a multi-region and remote renewable energy-fed urban power grid. This transition represents a practical realization of the ‘Energy Internet’ paradigm in the Asia-Pacific region. This letter provides a systematic introduction and discussion of the technical impacts and emerging challenges associated with Singapore's future interconnected power grid
