DayOne, a data center platform headquartered in Singapore, recently announced that it has reached a strategic partnership with Malaysia's National Energy Corporation to jointly explore the construction of an on-site self owned power system with a capacity of up to 1.5 gigawatts, providing power security for its new data center park in Sepang, Greater Kuala Lumpur. This move marks a new stage in DayOne's layout in the Malaysian market.

From Land Reserve to Electricity Autonomy

DayOne's expansion in Malaysia is extremely rapid. In August 2026, the company invested $152.8 million in cash to purchase a 78.8-acre freehold plot of land located in Sepang, Selangor from the Malaysian Star Group, which is part of the Southville City integrated development project. This is DayOne's third large-scale land acquisition in Malaysia in the past three months. Previously, the company had purchased 65 acres of land in Johor and integrated approximately 157 acres of industrial land in the Kapar area of Klang Valley. Its land reserves in the western peninsula of Malaysia are close to 300 acres, covering the three core nodes of Johor, Klang Valley, and Sepang.

Jamie Khoo, CEO of DayOne, stated that the company is deeply exploring an integrated architecture with TNB - directly embedding on-site self generation systems and battery energy storage systems into data center infrastructure, aiming to inject new power capacity and enhance overall system resilience. Prior to this, DayOne had signed a long-term power purchase agreement with TNB subsidiary through the Malaysian Enterprise Renewable Energy Supply Plan, covering 1.5GW of solar installations and 2.2GWh of battery storage. In addition, with the 500MW agreement signed in 2025, its total locked in renewable energy in Malaysia has exceeded 1GW.

The power game under the expansion of digital infrastructure

Behind the collaboration between DayOne and TNB is the sharp increase in electricity demand for data centers in Malaysia. Data shows that the peak demand for electricity in Peninsular Malaysia has exceeded 21.5GW in April 2026, and the electricity load of data centers has more than doubled from 452MW in the same period of 2025 to 1054 MW. It is expected that by 2035, the electricity consumption of data centers in Malaysia will reach about one-third of the total national power supply.

Faced with this trend, TNB has pledged to invest 4.3 billion ringgit in modernizing and upgrading the power grid. TNB President and CEO Datuk Ir. Ts. Shamsul Ahmad emphasized that responsible forward planning is not only to accurately meet the new electricity demand, but also to ensure the stability of the national power grid and help Malaysia achieve its long-term energy transformation goals. TNB has recently put into operation the first 100MW/400MWh grid type battery energy storage project in the Malaysian peninsula in Terengganu state, providing support for grid stability.

DayOne, formerly known as GDS International, the overseas business unit of Wanguo Data, was renamed and operated independently in 2025. In June of this year, it completed a $4.5 billion Series C financing and has reportedly submitted a secret IPO application for the US stock market, with a valuation of approximately $20 billion. With the dual support of capital and electricity, this data center newcomer's expansion in Malaysia has just begun.Editor/Cheng Liting
