DayOne Signs 500MW Solar Deal with TNB

Jun 13, 2025 | Posted by Abdul-Rahman Oladimeji

APACT data center firm DayOne has secured up to 500MW of solar power over 21 years from utility company Tenaga Nasional Berhad (TNB) to power its operations in Malaysia. Power will be provided by TNB’s renewable power subsidiary and power DayOne’s Nusajaya Tech Park, in Gelang Patah, and Kempas Tech Park, in Johor Bahru, which have a combined capacity of 120MW.

“Sustainability is core to how we build, operate, and grow. We’re embedding ESG principles across our value chain - from renewable energy transition to helping our customers decarbonize AI and cloud workloads,” said Jamie Khoo, CEO of DayOne.

The agreement was signed under the Corporate Renewable Energy Supply Scheme (CRESS), an initiative launched by the Malaysian Ministry of Energy Transition and Water Transformation in September 2024. CRESS permits corporations to directly contract power from renewable energy developers for electricity while paying a system access charge to the grid system operator for grid access.


Datuk Ir. Megat Jalaluddin Megat Hassan, president and CEO of Tenaga Nasional Berhad, called the agreement “a powerful signal of how a strategic collaboration can unlock reliable and scalable clean energy solutions for Malaysia’s most demanding digital infrastructures, including hyperscale data centers.”

There are 177 data centers in Malaysia.
