Malaysia expands clean energy capacity for data centres
A major solar and battery storage installation is planned in Malaysia to supply electricity for digital infrastructure under a corporate renewable framework.
Key points
- IOI Corporation and Tenaga Nasional Berhad are partnering on a 500 MW solar facility.
- The project includes a substantial battery storage system in Negeri Sembilan.
- Energy output is committed to DayOne Data Centres under a long-term offtake agreement.
What happened
A new utility-scale solar facility combined with large-scale battery storage is scheduled for construction in Bahau, Negeri Sembilan, according to pv magazine reporting from November 2026. The installation will feature 500 MW of photovoltaic capacity alongside a 250 MW battery system capable of storing 1,000 MWh of electricity.
IOI Corporation Berhad, an integrated palm oil producer, is collaborating with national utility Tenaga Nasional Berhad and local small and medium-sized enterprises to build the infrastructure across approximately 1,300 acres. DayOne Data Centres Limited, a Singapore-headquartered digital platform, will purchase the generated clean electricity across a 21-year timeframe.
The development operates through Malaysia's Corporate Renewable Energy Supply Scheme. This mechanism permits corporate entities to source green electricity directly from independent providers utilising the national transmission network, fostering private sector participation in low-carbon infrastructure.
Market adjustments and demand
Expansion of the domestic data centre sector has generated mounting requirements for reliable power supplies, placing pressure on grid capacity and dispatchable generation. In response to commercial viability concerns, authorities revised the supply scheme framework to improve project bankability, introducing a fixed system access charge and a minimum ten-year contract requirement for qualifying initiatives.
Prior policy updates and growing corporate registrations reflect broader efforts to integrate higher shares of intermittent renewables into national grids while managing electricity demand from energy-intensive technological facilities. World Bank statistics from 2021 indicate that renewables accounted for 17% of Malaysia's electricity output, while per capita electricity consumption reached 5,417.6 kWh by 2024.
Why it matters
For energy investors and policymakers across emerging markets, the Malaysian framework offers a case study in structuring corporate power purchase agreements to balance grid stability with rapid industrial demand growth. As digital infrastructure expands globally, the integration of utility-scale storage with solar installations highlights potential pathways for powering energy-intensive data hubs without destabilising national grids. African markets experiencing similar surges in digital infrastructure and constrained generation capacity can observe how regulatory clarity and direct procurement schemes influence private capital mobilization for renewable generation assets.

Context from CEII
Renewables are the fastest-growing part of the world’s energy system. The COP28 goal is to triple capacity by 2030, and solar mini-grids are the fastest route to power for millions of people without electricity.
