KUALA LUMPUR: Peak electricity demand from the data centre industry in Peninsular Malaysia is projected to reach 8.39 gigawatts (GW) by 2030, based on current electricity supply planning estimates, according to the Ministry of Energy Transition and Water Transformation (PETRA).
Of the total projected demand, Johor is expected to account for the largest share at 4.42 GW, followed by Selangor at 1.48 GW.
“Both states are major hubs for data centre development and will therefore require proper electricity supply infrastructure planning that takes into account the anticipated growth in demand,” it said.
PETRA was responding to a question from Onn Abu Bakar (PH-Batu Pahat) on the projected electricity and water demand from the data centre industry up to 2030, particularly in Johor and Selangor, as well as the number of data centres that had been completed.
The ministry said 45 data centres had been completed and were operational in Peninsular Malaysia as of August 2026, with a combined electricity supply capacity of 6.04 GW.
This capacity refers to the electricity supply provided by Tenaga Nasional Bhd through the National Grid to support the operation of the data centres.
Meanwhile, projected water demand from data centres in Selangor and Johor is expected to reach 389.04 million litres per day (MLD) by 2030.
“However, actual water consumption by data centres currently reported to the National Water Services Commission stands at 63.90 MLD,” PETRA said.
