Driven by rising demand for artificial intelligence (AI), Malaysia has rapidly emerged as a data centre hub in Southeast Asia, with growth concentrating in areas like Johor and Cyberjaya. The country has secured 8.3 GW of planned data centre capacity, which represents over two-thirds of all capacity under construction across ASEAN’s five main economies.

However, the explosive growth in data centres also comes with significant energy implications, with demand from data centres in the pipeline is projected to surpass 33 GW by 2040. At the same time, data centres are critical for all kinds of economic activity – from virtual meetings to AI-enabled energy forecasts – which they cannot provide without power.

The interdependence between data centres and energy systems creates a unique and rare opportunity to modernise the national grid. Malaysia can seize its data centre boom to build a future-ready energy system capable of powering AI growth, widespread electrification, as well as energy security and resilience.

Delivering flexibility and intelligence to the grid

newer generations of AI-enabled data centres are becoming far more flexible and intelligent in how they consume, manage, and optimise electricity

Globally, data centres are becoming one of the fastest growing and most complex sources of electricity demand – soaring by 17% in 2025, according to the International Energy Agency (IEA). By 2030, electricity consumption from data centres is expected to double, and triple for data centres that are particularly focused on AI workloads.

This rapid growth is reshaping how electricity systems operate, with AI data centres requiring increasingly large and dynamic amounts of power. Traditionally, utilities have always planned around relatively fixed patterns of energy demand, where electricity consumption remained largely constant regardless of broader grid conditions.

Nonetheless, newer generations of AI-enabled data centres are becoming far more flexible and intelligent in how they consume, manage, and optimise electricity. AI-based systems now allow data centres to adjust computing workloads in real time, shifting consumption away from peak periods and aligning with renewables’ availability.

These developments mark a broader shift from viewing data centres as passive energy consumers into active orchestrators enabling smarter, more adaptive energy systems. This growing synergy between data centres and power systems will become increasingly critical in enabling reliable, efficient, and low-carbon energy transitions.

Anchoring digital growth to the clean energy transition

Driven by emerging regulations and net-zero commitments, data centre developers are advancing efforts to actively decarbonise their energy-intensive facilities. This includes procuring renewable energy, entering long-term clean energy agreements, and supporting investments in energy storage and grid infrastructure to help create a more flexible and resilient power system.

Renewables like solar, wind, and hydro are already the fastest-growing source of electricity for data centres globally, projected to meet nearly 50% of demand until 2030. With the right institutional structure, data centre demand for green energy can be turned into a powerful engine for accelerating renewables integration.

Policymakers, utilities, and energy consumers can benefit from what data centres can provide: capital, load growth that justifies long-term grid investments, and tax revenue. Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS) is a good example, allowing companies to procure green power directly from generators on the grid.

Under the scheme, data centres pay a system access charge for the use of the grid, helping fund network upgrades needed to accommodate growing renewable energy capacity while supporting overall system reliability. For instance, the first bilateral supply agreement signed under this framework channels 500 MW of solar energy from TNB Renewables to hyperscale data centres in Johor. Recently at The Energy Transition Conference 2026 (ETCon26), DayOne and Tenaga Nasional Berhad (TNB) strengthened their renewable energy partnership through an agreement involving 1.5 GWp of solar capacity and 2.2 GWh of battery storage to support future large-scale solar and hybrid hydro-floating solar developments.

The total green energy take-up under the CRESS framework now stands at about 1.3GW, demonstrating how data centres can help expand clean energy capacity without burdening the electricity system. For the rakyat, this supports a more balanced transition, ensuring that energy remains affordable amid the integration of data centres into the national grid.

A more predictable, grid-ready pathway for sustainable growth

With the rapid expansion of data centres, there is also a growing need to ensure that new infrastructure remains aligned with long-term energy planning. Greater visibility into future electricity demand allows grid upgrades and renewables integration to be planned more proactively, supporting more efficient and resilient system growth.

TNB’s Green Lane Pathway supports this coordinated approach by creating a more structured and predictable pathway for data centres to establish their operations in Malaysia. The initiative also features fast-track clean electricity supply offerings, alongside dedicated support services to encourage earlier engagement. It has helped to reduce grid connection timelines for data centres from 36 months to as little as 12 months, with a total of 36 projects delivered as of March 2026.

This enables digital infrastructure growth to be integrated into broader grid readiness and energy planning rather than emerging in isolated clusters. Earlier planning visibility enables TNB to better prepare for incoming large-scale electricity demand and optimise renewable generation and storage capacity more effectively.

Over time, this approach could support a more resilient grid capable of balancing digital growth and long-term decarbonisation goals simultaneously. Ultimately, this creates a stronger foundation for Malaysia to scale its digital economy while advancing a more resilient and sustainable energy future.

Integrating data centres into Malaysia’s future-ready power grid

What was once an invisible backend of the digital economy is rapidly emerging as one of the most powerful drivers of global electricity consumption. But data centres will not just be running on electrons, they will become a critical part and feature of the energy system itself, empowering capabilities from dynamic grid balancing to faster demand response.

Beyond supporting the digital economy, data centres power many of the services people and businesses use every day – from online banking and digital payments to cloud storage, video streaming and AI-powered tools. As demand for these services continue to grow, ensuring that data centres are supported by a reliable and well-planned energy system will be increasingly important for consumers, businesses and the wider economy.

As AI adoption accelerates, data centres are evolving beyond traditional computing facilities into more energy-aware infrastructure that can better manage electricity demand, integrate renewable energy and support grid flexibility. This creates new opportunities for data centres and power systems to work more closely together in supporting the digital services and economic activities that increasingly rely on them.

Initiatives such as CRESS and TNB’s Green Lane Pathway demonstrate how data centre expansion can remain structured, sustainable, and beneficial for all energy users. Malaysia’s data centre boom can be more than an economic success story: it can lay the foundation for a smarter, more flexible and resilient power grid for generations to come.
