The Guide for Cross-Border Electricity Sales (CBES) serves as a comprehensive guide or framework in advancing ASEAN’s regional energy integration, facilitating power trade between Peninsular Malaysia and neighbouring countries, specifically Singapore and Thailand. The guide establishes two distinct schemes: the CBES Scheme, which governs non-renewable electricity exports, and the CBES RE Scheme, which enables the cross-border trade of renewable energy. Each scheme has its own set of regulatory requirements, infrastructure needs, and market mechanisms in shaping Malaysia’s role as an electricity exporter in the region.
