Malaysia is witnessing a significant surge in data-centre and cloud-computing investments, driven by the increasing demand for artificial intelligence, cloud services, and digital applications. This growth is opening up numerous opportunities for the workforce and local businesses but is simultaneously putting a strain on the nation’s electricity, water, and other infrastructure. During the first half of 2026, Malaysia approved investments totaling RM95.8 billion in this sector, making up nearly 44% of the country’s total approved investments for that period. Notably, Johor and the Klang Valley have become key hubs for the establishment of new facilities.
The burgeoning sector is creating a high demand for skilled professionals in various fields, including data science, engineering, cybersecurity, telecommunications, construction, electrical work, and facility management. These projects also present Malaysian companies with chances to provide essential services in construction, engineering, and electrical work, thus further boosting local industries.
One of the major challenges accompanying this expansion is the rising demand for electricity, as data centres require continuous power for their servers and cooling systems. In December 2025, electricity demand from data centres in Peninsular Malaysia reached 849 megawatts, with projections estimating an increase to 4,811 megawatts by 2030. To address this, the government plans to increase power-generation capacity by up to 9,600 megawatts between 2028 and 2031, aiming to meet the growing demand and replace outdated power facilities. Authorities are also scrutinizing electricity-use forecasts submitted by prospective data centres to prevent unnecessary infrastructure investments and manage additional costs effectively.
In addition to electricity, data centres are significant consumers of water, primarily for their cooling systems. Authorities are promoting the use of reclaimed and alternative water sources over treated drinking water to mitigate the impact on water resources. Johor has proposed plans to supply up to 12 million litres of reclaimed water daily for data-centre cooling, with similar initiatives underway in the Klang Valley. The government has also set requirements for new data-centre projects to ensure they have adequate power and water supplies and adhere to energy-efficiency standards. These standards include specific Power Usage Effectiveness (PUE) targets, capped at 1.6 for colocation facilities and 1.4 for hyperscale operators.
While Malaysia’s data-centre expansion is poised to deliver considerable economic and employment benefits, authorities are increasingly focused on ensuring that the industry’s growth does not overly burden the country’s electricity and water resources. By implementing strategic measures and encouraging sustainable practices, Malaysia aims to balance development with environmental stewardship.
