Amid rising demand for artificial intelligence, cloud services, and digital applications, Malaysia is witnessing a significant surge in investments related to data centres and cloud computing. This growth is paving the way for new job opportunities and business ventures while simultaneously exerting additional pressure on the nation’s infrastructure, including electricity and water resources. In the first six months of 2026 alone, Malaysia sanctioned RM95.8 billion in investments in this sector, which constituted nearly 44% of all approved investments during this period. Johor and the Klang Valley have become central hubs for these burgeoning facilities.
The expanding sector is creating employment opportunities in various fields such as data science, engineering, cybersecurity, telecommunications, construction, electrical work, and facility management. Furthermore, data-centre projects offer Malaysian companies chances to provide essential services like construction, engineering, and electrical work. As data centres require continuous operation, they demand substantial electricity for both servers and cooling systems. In Peninsular Malaysia, electricity consumption by data centres reached 849 megawatts by December 2025, with projections suggesting a rise to 4,811 megawatts by 2030.
In response to the increasing electricity demand, the Malaysian government is planning to expand power-generation capacity by up to 9,600 megawatts between 2028 and 2031 to accommodate the growing needs and replace old power plants. Authorities are also scrutinizing electricity-use forecasts submitted by proposed data centres to avert unnecessary infrastructure investments and manage additional costs effectively.
Data centres also rely heavily on water for their cooling systems, prompting authorities to advocate for the use of reclaimed and alternative water sources instead of depending solely on treated drinking water. Johor, for instance, has unveiled plans to supply up to 12 million litres of reclaimed water per day for data-centre cooling, and similar initiatives are underway in the Klang Valley. Additionally, the government has mandated that new data-centre projects demonstrate adequate power and water supplies and adhere to energy-efficiency standards.
To ensure sustainability, data centres must comply with specified Power Usage Effectiveness (PUE) targets, capped at 1.6 for colocation facilities and 1.4 for hyperscale operators. While the expansion of Malaysia’s data-centre industry is poised to bring substantial economic and employment advantages, authorities are increasingly concentrating on balancing this growth with the sustainable management of the nation’s electricity and water resources.
