Data centres’ power demand to hit 8.39GW by 2030, with Johor accounting for biggest share

Peak electricity demand for data centres in Peninsular Malaysia is projected to reach 8.39GW by 2030, with Johor requiring 4.42GW and Selangor 1.48GW.

As of August 2026, 45 data centres are operational in Peninsular Malaysia with a combined capacity of 6.04GW supplied by the National Grid.

Projected water demand for data centres in Johor and Selangor is 389.04 MLD by 2030, while current consumption stands at 63.90 MLD.

KUALA LUMPUR, Oct 20 — Peak electricity demand from the data centre industry in Peninsular Malaysia is projected to reach 8.39 gigawatts (GW) by 2030, based on the current electricity supply planning estimates, according to the Ministry of Energy Transition and Water Transformation (Petra).

Of the total amount, Johor is expected to record the highest demand for electricity at 4.42GW, and Selangor at 1.48GW.

“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.

The ministry was responding to a question from Onn Abu Bakar (PH-Batu Pahat) on the projected electricity and water demand by the data centre industry up to 2030, particularly in Johor and Selangor, as well as the number of data centres that have been completed.

Petra said 45 data centres had been completed and were operational in Peninsular Malaysia as of August 2026, with a combined electricity supply capacity of 6.04GW.

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, the 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. — Bernama

预计到 2030 年，马来西亚半岛数据中心的峰值电力需求将达到 8.39 吉瓦，其中柔佛州需要 4.42 吉瓦，雪兰莪州需要 1.48 吉瓦。

截至 2026 年 8 月，马来西亚半岛共有 45 个数据中心投入运营，总容量为 6.04GW，由国家电网供电。

预计到 2030 年，柔佛州和雪兰莪州数据中心的用水需求将达到 389.04 MLD，而目前的用水量为 63.90 MLD。

吉隆坡，10 月 20 日——根据能源转型和水务转型部 (Petra) 的预测，根据目前的电力供应规划估算，到 2030 年，马来西亚半岛数据中心行业的用电高峰需求预计将达到 8.39 吉瓦 (GW)。

在总用电量中，柔佛州预计用电量最高，达 4.42 吉瓦，其次是雪兰莪州，为 1.48 吉瓦。

报告称：“这两个州都是数据中心发展的重要中心，因此需要进行适当的电力供应基础设施规划，以考虑到预期的需求增长。”

该部门是在回应翁阿布巴卡（希望联盟-峇株巴辖）提出的问题时做出上述表态的。翁阿布巴卡询问了数据中心行业到 2030 年的预计电力和用水需求，特别是柔佛州和雪兰莪州的需求，以及已建成的数据中心数量。

Petra 表示，截至 2026 年 8 月，马来西亚半岛已有 45 个数据中心建成并投入运营，总供电能力为 6.04 吉瓦。

该容量指的是国家能源公司通过国家电网提供的电力供应，以支持数据中心的运行。

与此同时，预计到 2030 年，雪兰莪州和柔佛州数据中心的用水需求将达到每天 3.8904 亿升（MLD）。

佩特拉表示：“然而，目前向国家水务委员会报告的数据中心实际用水量为每日6390万升。”——马新社
