• Authorities have conducted joint raids since 2020, shutting down thousands of unauthorized mining setups and addressing grid instability caused by illicit operations.
• TNB has expanded its smart meter network, enabling real-time monitoring to detect abnormal consumption patterns and prevent future theft.
