Siting floating solar PV arrays on reservoirs at TNB’s existing hydroelectric power plants, a 100kW pilot was launched just under a year ago, as reported by our colleagues at PV Tech.

For DayOne, the clean energy and storage capacity will be used to decarbonise its operations in Malaysia.

The data centre developer has a development pipeline of projects in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong and most recently Finland. It wants to reach 100% renewable energy across its operations by 2030 or earlier and reduce Scope 1 and Scope 2 emissions by 42% in absolute terms from a 2025 baseline.

“As demand for AI and cloud infrastructure accelerates, securing long-term access to renewable energy is critical,” said DayOne CEO Jamie Khoo, who called the deal “an important milestone in how we scale digital infrastructure responsibly.”
