Singapore-based digital infrastructure company DayOne Data Centers Limited has signed a major renewable energy supply agreement with Tenaga Nasional Berhad (TNB), securing more than 1 gigawatt (GW) of renewable energy capacity to power its growing data center operations in Malaysia.
The agreements, signed with TNB subsidiaries TNB Renewables Sdn. Bhd. and TNB Power Generation Sdn. Bhd., represent one of the largest renewable energy procurement deals in Malaysia’s digital infrastructure sector. The signing ceremony was witnessed by Malaysian Prime Minister Anwar Ibrahim and senior government officials.
Structured under Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS), the partnership includes approximately 1.5 gigawatt-peak (GWp) of solar generation capacity and 2.2 gigawatt-hours (GWh) of battery energy storage. The projects will combine ground-mounted solar facilities and hybrid hydro-floating solar systems, providing clean and reliable power for DayOne’s hyperscale data centers.
The agreement marks a significant milestone in DayOne’s sustainability strategy. Alongside renewable energy certificates (RECs), the contracts support the company’s goal of achieving 100% renewable energy usage across its global platform by 2030 or earlier, while targeting a 42% reduction in Scope 1 and Scope 2 emissions from its 2025 baseline.
This latest deal expands upon a previous agreement signed in 2025, which secured 500 megawatts of renewable energy for DayOne’s Malaysian operations over a 21-year period. Combined, the two agreements provide DayOne with more than 1GW of renewable energy capacity in Malaysia.
The partnership also aligns with Malaysia’s National Energy Transition Roadmap (NETR), which aims to increase renewable energy’s share of installed power capacity to 70% by 2050 and achieve net-zero greenhouse gas emissions as early as 2050. As demand for cloud computing, artificial intelligence, and hyperscale data centers continues to rise, access to sustainable energy has become a critical factor for technology companies investing in the region.
DayOne currently operates major hyperscale campuses in Nusajaya Tech Park and Kempas Tech Park and plans to invest approximately RM28 billion in Malaysia by the end of 2026, making the country its largest operational market globally.
Industry observers view the agreement as a landmark achievement under the CRESS framework, positioning Malaysia as an increasingly attractive destination for data center investments backed by large-scale renewable energy resources.
