DayOne Data Centers Limited and Sembcorp Utilities Pte Ltd will examine power options for DayOne’s Asian data centers, while Sembcorp says AI adoption is making the sector’s energy requirements more complex.
The companies signed a memorandum of understanding Oct. 29. It sets out a review of power and energy solutions but does not commit either side to a project or supply deal. Sembcorp Utilities, a wholly owned subsidiary of Sembcorp Industries, will serve as technical partner on selected projects.
The review could include on-site generation and electrical infrastructure, renewable energy, fuel supply and storage, as well as operations and maintenance. DayOne said the parties will test whether options are feasible and commercially justified, then consider possible ways to put them into practice for projects selected for review.
The companies have not identified locations or capacity figures, or disclosed investment amounts, prices, who would cover costs or an implementation schedule. They also gave no date for a next decision.
DayOne describes its “Bring Your Own Power” approach as bringing electricity planning into earlier stages of data center development. The company says this is meant to limit execution risks and offer customers more certainty where power is constrained. It aims to source 100% renewable energy by 2030 when market conditions permit.
The new review comes alongside other energy arrangements already announced by DayOne. The company says renewable energy under an existing Sembcorp power purchase agreement will serve its upcoming SG1 data center in Singapore. Agreements announced in Malaysia in June 2026 cover about 1.5 GWp of solar capacity and 2.2 GWh of battery storage. Those arrangements were announced separately from the new memorandum.
Koh Chiap Khiong, President and CEO, Gas and Related Services at Sembcorp, said, “Powering AI will require energy solutions that can keep pace with the scale and pace of data centre growth.” Sembcorp has linked the growing use of AI to more complex energy requirements for data centers.
