Singapore-based digital infrastructure company DayOne Data Centers has entered into major renewable energy supply agreements in Malaysia with subsidiaries of Tenaga Nasional Berhad (TNB), marking a significant step toward sustainable digital infrastructure development. The agreements were signed with TNB Renewables and TNB Power Generation under Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS), which allows businesses to directly purchase renewable electricity from project developers. The signing ceremony was attended by Malaysian Prime Minister Anwar Ibrahim and other senior government officials.
The newly signed agreements cover approximately 1.5 gigawatt-peak (GWp) of solar power generation capacity and 2.2 gigawatt-hours (GWh) of battery energy storage systems. The projects will include a combination of ground-mounted solar farms and hybrid hydro-floating solar installations. In addition to supplying clean electricity, the agreements also provide for the transfer of renewable energy certificates, helping DayOne achieve its sustainability and environmental goals.
The renewable energy generated through these projects will support DayOne’s large-scale data center operations in Malaysia. These facilities provide critical digital infrastructure services, including cloud computing, artificial intelligence (AI), and other advanced technology applications. The move reflects the growing demand for reliable and sustainable power sources as digital infrastructure continues to expand across the region.
The latest agreements build upon an earlier partnership established in June 2025, when DayOne secured 500 megawatts of renewable energy through a 21-year contract. With the addition of the new agreements, the company has now secured more than 1 gigawatt (GW) of renewable energy capacity in Malaysia through its collaboration with TNB. This achievement positions DayOne among the first major corporations to successfully execute renewable energy contracts under Malaysia’s national CRESS framework.
The partnership also supports Malaysia’s National Energy Transition Roadmap, which targets net-zero greenhouse gas emissions by 2050. Industry observers view the development as an important milestone in strengthening Malaysia’s position as a leading digital and technology hub in Southeast Asia, particularly for global companies seeking sustainable energy solutions for data centers.
DayOne currently operates major data center campuses at Nusajaya Tech Park and Kempas Tech Park. The company expects its cumulative investments in Malaysia to reach 28 billion ringgit by the end of 2026, making the country its largest global operational hub.
DayOne Chief Executive Officer Jamie Khoo stated that long-term access to clean energy is essential for responsibly expanding digital infrastructure as demand for AI and cloud services continues to grow. TNB President and CEO Shamsul bin Ahmad said the CRESS framework is helping increase corporate access to sustainable and resilient energy solutions while supporting the growth of the digital economy.
