SHAH ALAM, July 7 — Tenaga Nasional Berhad (TNB) will carry out a comprehensive technical assessment to evaluate the capacity of the existing electricity grid before approving power supply applications for hyperscale data centres in Serendah.
Energy Transition and Water Transformation Minister Fadillah Yusof said the study will assess the adequacy of current power generation capacity and the capability of the electricity transmission and distribution systems to accommodate additional demand from the proposed projects.
There are currently three projects in Serendah applying for electricity supply from TNB.
“One of the projects has applied to commence operations in 2026, with an electricity requirement of up to 300 megawatts.
“Before any electricity supply application is approved, TNB will conduct a detailed technical study to evaluate the capability of the existing grid system,” he said.
Fadillah was responding to Hulu Selangor MP Mohd Hasnizan Harun's query via a written reply during the Dewan Rakyat sitting today, regarding studies on electricity and water consumption for hyperscale data centre projects in Serendah, as well as the ministry's (PETRA) measures to ensure utility supplies to nearby residents would not be affected.
He added that approval for the electricity supply would be granted only if the assessment confirmed that both existing and planned infrastructure could accommodate the increased demand from the projects.
The approval would also be subject to the system's ability to maintain the quality, stability, and reliability of electricity supply for existing consumers, particularly residents living in the surrounding areas.
“PETRA, together with the Energy Commission, continuously monitors the growth in electricity demand resulting from the rapid expansion of data centre developments,” Fadillah said.
He noted that the expansion of power generation capacity and grid infrastructure is being carried out in an integrated manner through Malaysia's annual electricity supply system planning process.
“This planning takes into account demand growth from all sectors of the economy, including data centres, to ensure that Malaysia's electricity supply system remains stable and reliable in the future,” Fadillah said.
