DayOne and Sembcorp Partner on Bring Your Own Power Initiative
APAC developer DayOne and Singaporean utility Sembcorp sign a memorandum to integrate dedicated on-site power and renewables across Asian data centers
Asia-Pacific data center operator DayOne has signed a non-binding Memorandum of Understanding with Singaporean energy company Sembcorp Utilities to evaluate and integrate dedicated power solutions across DayOne's growing data center footprint in Asia. The partnership forms a key part of DayOne's "Bring-Your-Own-Power" strategy, which seeks to lock in on-site power generation, electrical infrastructure, fuel storage, and renewable energy supply at the earliest stages of facility development as power grid constraints intensify across regional markets.
Key details
Under the agreement, DayOne and Sembcorp Utilities will assess energy pathways across several operational areas, including on-site generation, renewable energy supply, electrical infrastructure, fuel supply and storage, and long-term operations and maintenance services. The companies announced that the framework aims to provide cost-competitive, reliable power to support energy-intensive artificial intelligence workloads while avoiding execution bottlenecks caused by regional utility backlogs.
The initiative comes as DayOne accelerates its regional buildout ahead of a planned Initial Public Offering on the Nasdaq stock exchange. According to the company's IPO prospectus, DayOne had 962 MW of data center capacity in service as of late September 2026, up from 675 MW in June. An additional 1.3 GW of capacity is currently under construction, with delivery targeted by December 2028.
In Malaysia, DayOne operates 120 MW across two campuses in Johor—located in Nusajaya Tech Park and Kempas Tech Park—and has acquired land in Selangor and Johor to support future expansion. Earlier this year, the operator partnered with NB Power Generation, a subsidiary of Malaysian national utility Tenaga Nasional Berhad, to explore up to 1.5 GW of on-site power generation for its Selangor development. The new pact with Sembcorp builds upon a prior ten-year Power Purchase Agreement signed between the two companies for bundled renewable energy certificates sourced locally or imported via cross-border grid links.
Why this matters
The agreement highlights the rapid shift among hyperscale and AI data center developers toward "Bring Your Own Power" models as national transmission grids struggle to meet soaring compute loads. Instead of waiting years for public grid interconnections, operators are increasingly contracting directly with utility and energy partners to engineer dedicated power generation, fuel logistics, and high-voltage electrical infrastructure alongside facility construction.
For the Asia-Pacific digital infrastructure sector, pairing large-scale computing campuses with bespoke on-site energy solutions helps reduce delivery delays and prevents volatile wholesale power pricing from derailing multi-gigawatt development pipelines.
Context
As artificial intelligence models scale in complexity, data centers require unprecedented power densities and continuous baseload reliability. In major Southeast Asian hubs such as Singapore and Johor, electrical transmission capacity and renewable supply have become primary constraints on new infrastructure approvals.
Sembcorp has increasingly positioned itself as a key power partner for digital infrastructure providers in the region. Sembcorp recently signed an agreement with Nxera Singapore to supply low-carbon energy to its facilities, and in March 2026 finalized a 25-year contract with Meta subsidiary Malkoha Pte to build, own, and operate a 150 MW floating solar project in Singapore.
Risks and open questions
The Memorandum of Understanding remains non-binding, meaning specific project deployments, generation technologies, capital allocation, and commercial terms have yet to be finalized in definitive contracts. Implementing on-site power generation at gigawatt scale also presents technical and regulatory challenges, including securing fuel supplies, managing emissions from transitional thermal generation, and obtaining local environmental and zoning permits across diverse jurisdictions in Asia.
Furthermore, balancing immediate baseload power reliability with long-term regional decarbonization targets will require integrating renewable energy certificates and cross-border clean power imports without straining local utility networks.
What happens next
DayOne and Sembcorp will work to formalize operational agreements establishing project frameworks for target sites across DayOne's pipeline in Asia. DayOne is simultaneously advancing its Nasdaq IPO while progressing construction on its 1.3 GW pipeline across Malaysia and neighboring markets, with major initial deliveries scheduled through 2028.
