DayOne and Sembcorp Sign MOU on Power Solutions for Asian Data Centers
DayOne Data Centers and Sembcorp Utilities have signed a Memorandum of Understanding to explore integrating power and energy solutions into DayOne's data center developments across Asia. The agreement supports DayOne's "Bring Your Own Power" initiative, which builds power planning into the earliest stages of a project.
- DayOne Data Centers and Sembcorp Utilities signed an MOU to explore power and energy solutions for DayOne's Asian data centers.
- Areas include on-site power generation, renewable energy supply, and operations and maintenance services.
- The deal supports DayOne's "Bring Your Own Power" initiative, which plans power at the earliest development stage.
- DayOne targets 100% renewable energy by 2030, where market conditions allow.
- Existing deals cover Singapore (SG1), Malaysia (CRESS, about 1.5GWp solar and 2.2GWh storage) and Thailand (Chonburi Tech Park).
What the MOU covers
DayOne Data Centers is a Singapore-headquartered digital infrastructure platform. Sembcorp Utilities is a wholly owned subsidiary of Sembcorp Industries. Under the MOU, the two companies would evaluate solutions in areas including on-site power infrastructure and generation, renewable energy supply, and operations and maintenance services.
The parties intend to jointly assess the feasibility, business case and potential implementation pathways for energy solutions tied to agreed projects. According to the release, the framework also lets them explore reliable and cost-competitive power solutions, electrical infrastructure, fuel supply and storage, and associated technical and operational services.
The document is an MOU, so it sets out areas of exploration rather than binding projects or capacity figures. The release gives no financial terms or timelines.
The "Bring Your Own Power" approach
The collaboration supports DayOne's "Bring Your Own Power" initiative. According to the company, it integrates power planning into the earliest stages of data center development to identify and secure suitable energy solutions. DayOne says the approach aims to reduce execution risk, navigate increasingly constrained power markets and give customers greater certainty as they scale.
Jamie Khoo, CEO of DayOne, said: "Scaling digital infrastructure means thinking about the energy pathways powering it from the outset." He added that DayOne aims to secure critical resources early, naming power, land, water and connectivity.
Koh Chiap Khiong, President & CEO, Gas and Related Services at Sembcorp, said: "Powering AI requires energy infrastructure to grow alongside digital infrastructure."
Existing power deals across the region
The MOU builds on DayOne's current energy initiatives. The company targets 100% renewable energy by 2030, where market conditions allow. The release lists several existing arrangements:
- Singapore: a Power Purchase Agreement with Sembcorp for the upcoming SG1 Data Center, where operations will be fully covered by renewable energy.
- Malaysia: renewable energy supply agreements announced in June 2026, covering approximately 1.5GWp of solar capacity and 2.2GWh of battery energy storage under the Corporate Renewable Energy Supply Scheme (CRESS).
- Thailand: a Power Purchase Agreement to supply renewable energy to the Chonburi Tech Park data center campus.
What it means for customers and the market
DayOne frames power as one of the industry's biggest constraints and says it wants to turn it into an enabler of growth. The stated aim is to give customers more confidence that capacity can be delivered at speed, when and where they need it.
DayOne was established in 2022 and says it has a footprint across ten markets in Asia Pacific and Europe, with operations in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, Finland and Spain. It describes its customers as leading global hyperscalers and businesses. Whether the MOU leads to concrete projects will depend on the feasibility and business case work the two companies now plan to carry out.
