IOI and TNB Partner on 500MW Solar Project with 1GWh Battery Storage in Malaysia

Project marks IOI’s first large-scale renewable energy development under Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS)

BAHAU, Negeri Sembilan, Malaysia – IOI Corporation has entered into a strategic partnership with TNB Renewables and a consortium of small and medium-sized enterprises (SMEs) to jointly develop a 500MWac solar photovoltaic (PV) project integrated with a 250MW/1,000MWh battery energy storage system (BESS) in Bahau, Negeri Sembilan, Malaysia.

The project represents IOI Corporation’s first large-scale renewable energy development under Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS), reflecting the company’s growing commitment to renewable energy and sustainable development.

Key project highlights include:

• 500MWac of solar PV capacity integrated with a 250MW/1,000MWh BESS.

• Approximately 1,300 acres of land secured through a long-term lease agreement.

• A 21-year electricity offtake agreement with DayOne Data Centres, covering up to 500MWac of renewable electricity supply.

  
  

The integration of large-scale solar generation and battery storage is expected to support the delivery of renewable electricity while enhancing the flexibility and reliability of power supply.

The project also highlights the growing role of corporate renewable energy procurement and energy storage in meeting the rising electricity demand of Malaysia’s data centre sector.
