Malaysia's Crypto Mining Dilemma: Stolen Power vs. Untapped Economic Potential

Malaysia's national utility company Tenaga Nasional Bhd (TNB) has lost over $1.1 billion in electricity revenue due to illegal cryptocurrency mining operations since 2020, according to the Energy Transition and Water Transformation Ministry. The ministry disclosed in a parliamentary reply that 13,827 premises nationwide were found to have used electricity without authorization for mining, primarily Bitcoin, between 2020 and August 2025, resulting in RM4.57 billion ($1.11 billion) in losses. The scale of the theft has prompted a multi-agency crackdown, including joint operations with police, the Malaysian Anti-Corruption Commission, and other enforcement bodies to seize mining equipment and shut down illicit operations.

The ministry highlighted that TNB has implemented measures to combat the issue, including the creation of a database to track suspected premises and tenants, installation of smart meters for real-time energy monitoring, and public awareness campaigns to deter theft according to the ministry's statement. Smart meters, part of a pilot project, are now deployed at substations to detect tampering and unusual consumption patterns. TNB is also exploring artificial intelligence and predictive analytics to enhance detection capabilities according to industry reports.

Legal consequences for offenders are severe, with penalties under the Electricity Supply Act including fines of up to RM1 million, imprisonment for up to 10 years, or both. The ministry emphasized that such activities pose risks to public safety, national energy stability, and infrastructure integrity according to the ministry's analysis. Despite these efforts, the lack of specific regulatory frameworks for cryptocurrency mining remains a challenge. While mining itself is not illegal, the absence of licensing and clear electricity pricing structures has created a gray area, leaving operators vulnerable to enforcement actions under existing laws according to financial analysts.

The surge in illegal mining has strained Malaysia's grid infrastructure, with operations often conducted in low-traffic locations like warehouses and residential buildings to avoid detection. These setups bypass meters to tap directly into the grid, consuming energy equivalent to entire residential blocks while frequently relocating to evade authorities according to Reuters reporting. The ACCESS Blockchain Association estimates that formalizing the sector could unlock RM700 million in investments and create 4,000 jobs, but regulatory clarity is needed to harness this potential according to industry analysis.
