As data centres become the core of the AI economy, their greatest constraint is no longer compute, it’s power. For investors, founders, and operators in Southeast Asia, this convergence of artificial intelligence and energy presents both a bottleneck and a generational opportunity. This is our view from The Radical Fund: the next frontier of digital progress will come from climate-aligned infrastructure that fuses intelligence with power.

Over the following sections, we explore:

• The challenge: How exponential data and compute demand are colliding with the physical limits of energy systems
• The shift: Why efficiency alone is no longer enough, and how system-level innovation is reshaping the data centre model
• The regional lens: Why Southeast Asia, with billions in FDI and a fast-digitising economy, is uniquely positioned to lead this transition
• The opportunity: Where investors and founders can enable scalable solutions in cooling, compute, energy integration, and grid resilience

Digital abundance meets physical constraint

Artificial intelligence is redefining the boundaries of computation, data, and productivity. Yet behind every model, every query, and every algorithm sits a data centre consuming colossal amounts of power. Global data centre demand is projected to more than double by 2030, rivaling Japan’s total annual electricity use. The infrastructure built to enable the digital economy is colliding with the physical limits of energy systems that were designed for a different century.

Energy has become the new bottleneck of AI progress, the physical constraint in a digital race. Hyperscale facilities that power today’s cloud and AI workloads already account for roughly 1.5 per cent of global electricity consumption. This share is growing quickly as AI training and inference workloads multiply.

Nowhere is this constraint more visible than in Southeast Asia. The region is witnessing a surge of digital activity and foreign direct investment into hyperscale data centres. Malaysia, Indonesia, and the Philippines are positioning themselves as new digital gateways. Malaysia alone has announced more than MYR 99 billion, or US$23 billion, in planned data centre investments since 2023. Indonesia and the Philippines are following closely behind. Yet the regional grid remains fossil-heavy, underinvested, and unevenly modernised.

The world’s most advanced computation networks are running on infrastructure built for another era. Without rapid innovation at the intersection of energy and intelligence, the very systems driving the AI revolution could face their own energy ceiling.

The energy makeup of intelligence

A modern data centre is, in essence, a miniature energy ecosystem, with roughly 40 per cent of total energy use going to compute, and another 40 per cent to cooling. Both are rising sharply as high-performance GPUs replace traditional CPUs and as AI workloads scale.

Each hyperscale facility now draws as much power as a small city. Johor, Malaysia’s emerging AI hub, could account for nearly 30 per cent of national power consumption by 2030 if all planned capacity comes online. The concentration of demand is staggering.

Power Usage Effectiveness, or PUE, has long been the industry’s benchmark for efficiency. A perfect score of 1.0 means every watt powers computation alone. Yet even the most advanced facilities, with PUE ratios near 1.1, face a bigger challenge: total power demand is compounding at double-digit rates. Incremental improvements can no longer offset exponential growth. The conversation must shift from energy saving to system redesign.

This is not just a sustainability issue. It is an economic one. Energy costs account for between 30 per cent – 50 per cent of total data centre operating expenses. As power tariffs rise and emissions rules tighten, energy strategy becomes synonymous with business strategy.

The required system-level shift from efficiency to integration

The data centre industry has long approached sustainability as a collection of independent problems: efficiency on one side, compute on another, and grid supply somewhere outside the fence. That era is ending. The next generation of digital infrastructure will be designed as an integrated system, where power, heat, and compute flow dynamically across the same operational stack.

Southeast Asia offers fertile ground for this transformation. In Singapore and Malaysia, operators are testing liquid and immersion cooling systems capable of handling the extreme thermal densities of AI chips. These technologies replace traditional air-conditioning with precision systems that use water or non-conductive liquids to extract heat directly from processors. In a region where temperatures are high and land is scarce, the shift from air to liquid cooling can reduce cooling energy use by roughly a third, according to industry benchmarks, while freeing up space for more compute.

Integration extends beyond cooling. Graywater recycling and waste-heat recovery are becoming viable in data parks connected to urban industrial clusters. In Singapore, treated wastewater already accounts for over 40 per cent of the national supply, setting a foundation model for closed-loop cooling systems. In cooler regions such as Europe, wasted data centre heat is being reused in district heating systems. In time, Southeast Asia may find its own circular approaches suited to tropical climates and water scarcity.

The most significant leap will come from software addressing incompatible systems. Digital twins and real-time analytics platforms are emerging to orchestrate infrastructure dynamically, predicting load shifts, adjusting cooling, and optimising power flows without new hardware. This software-defined approach blurs the line between IT and energy operations, creating adaptive, self-optimising systems. Efficiency becomes not a fixed objective but a continuous function.

Energy independence as a strategy

Even as integration advances, the grid itself is becoming a constraint. Across Asia, grid connection delays now exceed data centre build times. In hotspots like Johor and Batam, connection queues stretch for years. Meanwhile, fossil price volatility, emission caps, and renewable intermittency have made energy planning both more complex and more strategic.

Forward-looking operators are responding with on-site generation and storage, together with hybrid power models that provide autonomy and resilience:

• Co-located solar and battery systems that offset daytime load and stabilise supply;
• Hydrogen-ready microgrids that future-proof against fossil fuel volatility; and
• Small modular reactors (SMRs) are being explored for stable, round-the-clock baseload power.

These models reduce exposure to fossil volatility and regulatory tightening, providing the ability to stay online when the grid cannot.

Energy independence is fast becoming a driver of valuation. Facilities that adhere to renewable integration standards, interconnection requirements, and carbon-reduction mandates face lower operational risk and, therefore, lower weighted average cost of capital. For investors, this translates into higher exit multiples. What began as environmental compliance is now a form of financial resilience.

The narrative is evolving from green compliance to energy resilience, from sustainability as an obligation to sustainability as a competitive advantage. The AI revolution will not be won in the cloud, but in the power grid that sustains it.

The new asset class: AI-ready infrastructure

A new category of infrastructure is emerging, one that is intelligent, efficient, and sovereign. Energy-smart data centres will define the 2030s, and the convergence of compute, energy, and regulation will shape not only the digital economy but also national competitiveness.

Southeast Asia is already becoming a stage for this transformation. Singapore remains the premium ESG benchmark, but with limited land and water, it is guiding regional standards rather than expanding capacity. Malaysia has seized the opportunity, attracting a wave of investment from global hyperscalers. Indonesia is rising fast, driven by its massive population and government incentives. The Philippines and Vietnam are catching up as connectivity improves.

This FDI surge is more than a capital inflow. It signals a strategic repositioning. Nations are competing not just to host data but to control the digital-physical nexus of energy and computation. The outcome will determine who captures the value created by the AI economy.

Investors, policymakers, and builders are no longer operating in silos. They are co-designing an ecosystem where energy efficiency, grid intelligence, and data sovereignty intersect. For capital allocators, this presents a generational opportunity: to fund the foundations of an AI-ready, climate-aligned digital economy.

The next decade

The next decade will test whether the world can reconcile digital expansion with environmental limits. The AI era is not merely a software story; it is an energy story. Without reinvention at the infrastructure level, capacity, cost, and carbon will become binding constraints on innovation.

Southeast Asia stands at the forefront of this challenge. Its economies are growing rapidly, its populations are digital-first, and its geography places it at the crossroads of East and West. Yet its energy systems remain among the most carbon-intensive. Bridging that gap requires imagination and investment in equal measure.

This region can lead by designing the next generation of infrastructure from first principles, embedding energy intelligence into every layer of the digital stack. Governments can align data-centre policy with national energy transition plans, accelerating renewable integration and storage. Investors can support technologies that couple compute density with sustainability. Operators can adopt circular resource models for heat, water, and hardware.

Southeast Asia has the resources, capital, and talent to shape this future. The question is whether it will choose to lead or wait for others to define the standards.

At The Radical Fund, our view is clear. The AI revolution depends on reinventing energy infrastructure. The region that succeeds in aligning power with intelligence will not only fuel its digital growth, but it will also own the foundations of the next economy.
