Time to Halt New Data Centres?

 

Malaysia's rise as a regional data-centre hub has been hailed as evidence that the country is becoming a major player in the digital economy. Many Ministers proudly announce billions of ringgit in investments from global technology giants. State governments compete to attract new projects. Consultants celebrate Johor's emergence as Southeast Asia's data-centre capital. One fundamental question however, is being neglected: Should Malaysia continue approving new data centres when many Malaysians still face concerns over water security, electricity reliability and rising utility costs?

Before arguing for a moratorium, it is important to establish the scale of Malaysia's data-centre boom and the growing concerns over electricity and water security. Malaysia has emerged as Southeast Asia's fastest-growing data-centre hub, driven largely by demand from global technology companies relocating capacity from Singapore and expanding AI infrastructure. Key figures include:

 

·           Between 2021 and June 2025, the federal government approved 143 data-centre projects with total investments of RM144.4 billion.

·           As of early 2026, Malaysia reportedly had 34 operational data centres and 33 more under development, according to Malaysia Digital Investment Department data.

·           Johor, Selangor and Negeri Sembilan together host around 101 data centres, with Johor accounting for about 72 facilities, making it the country's main data-centre hub.

·           Johor alone had 51 approved projects by late 2025, of which 17 were operational and 11 under construction.

Malaysia's operational data-centre capacity is projected to grow from roughly 1,025 megawatts (MW) at the end of 2025 to more than 2,000 MW by the end of 2026, with an additional 3,500 MW in the pipeline. 

By the end of 2024, 38 projects had already secured electricity supply agreements with a combined maximum demand of 5.9 gigawatts (GW), equivalent to approximately 43% of Tenaga Nasional's contracted capacity. 

Malaysia's National Water Services Commission (SPAN) estimates that 104 data centres could require approximately 876 million litres of water daily for cooling purposes. 

At the same time, Malaysia is already experiencing record electricity demand. Reuters reported in May 2026 that power demand in Peninsular Malaysia rose by 11.5% year-on-year, driven partly by data-centre expansion and extreme heat. Energy analysts expect electricity demand to continue growing by about 4% annually, largely because of data centres.  The federal and state governments should impose a moratorium on approving new data centres until they can guarantee adequate energy and water supplies for citizens and local industries. 

Unlike manufacturing plants that create large numbers of jobs and extensive supply chains, modern hyperscale data centres consume enormous quantities of electricity and water while employing relatively few workers once construction is completed.  This growth is being driven largely by artificial intelligence, cloud computing and the relocation of facilities from Singapore, where land, water and energy constraints have forced policymakers to slow expansion.  

The crucial question is not whether Malaysia can eventually generate more electricity. The question is whether Malaysian households and local industries should compete with foreign-owned data centres for power supply. No government should approve projects that could jeopardise domestic energy security. 

Before a single new data-centre licence is granted, the government should publicly demonstrate:

·                     sufficient reserve electricity margins;

·                     guaranteed domestic supply for households;

·                     no increase in electricity tariffs arising from data-centre demand;

·                     adequate grid infrastructure; and

·                     clear renewable-energy commitments from operators. 

Without such guarantees, citizens are effectively subsidising private digital infrastructure. Should they not pay a higher tariff for both power and water? They (data centres) should subsidise building of new facilities. 

Malaysia is not alone in facing this dilemma. Many governments are beginning to ask whether the economic benefits justify the environmental and infrastructure costs. Malaysia should ask the same questions:

 

·                     What is the real return to society from these projects?

·                     How many permanent jobs do they create?

·                     How much tax revenue do they generate after incentives?

·                     What are the long-term costs to water systems, electricity networks and public infrastructure?

The federal government and state governments should jointly suspend approvals for new data centres until the following conditions are met:

 

·                     Independent assessments confirm adequate long-term electricity supply.

·                     Independent assessments confirm adequate water availability.

·                     Citizens' domestic consumption is guaranteed priority access.

·                     Data-centre operators pay the full environmental and infrastructure costs they impose.

·                     Mandatory renewable-energy targets are enforced.

·                     Full transparency is provided regarding water and electricity consumption.

·                     Highter tariffs for data centres. 

Malaysia should embrace digital development, but not at the expense of its people. Economic growth must serve society, not the other way around. When electricity and water become scarce, the first responsibility of government is to citizens, not foreign investors.
