# ASEAN Data Centres Face Urgent Power Demand and Capacity Challenges > As data centre demand skyrockets in ASEAN, energy providers face a critical challenge to integrate new loads sustainably, potentially reshaping the competitive landscape in the power sector. **Source**: aseanenergy.org | **Published**: 2026-11-12 | **Type**: article ## Key Facts - ASEAN data centres may consume 171–258 TWh by 2035, highlighting urgent power demand growth. - To meet demand, 53.5–82.0 GW additional capacity is needed, emphasizing strategic energy planning. - Connection timelines may dictate data centre locations, revealing vulnerabilities in infrastructure readiness. - Flexibility can cut capacity needs by 30%, indicating a competitive edge for adaptable energy solutions. - 53 of 100 operators target net-zero, signaling a shift towards renewable investments in the sector. ## Summary The rapid expansion of data centres in the ASEAN region is poised to significantly impact local power systems, with electricity consumption projected to soar from approximately 20 terawatt-hours (TWh) in 2023 to between 171 and 258 TWh by 2035. This surge in demand arises from the ongoing digitalisation across industries, which necessitates a strategic response to ensure sustainable integration of this new load into existing power frameworks. The implications are profound, as they not only affect energy supply but also shape the competitive landscape for energy providers and technology firms alike. To meet the anticipated demand from data centres, ASEAN countries may need to add between 53.5 and 82.0 gigawatts (GW) of new power capacity by 2035. The Reference case indicates that approximately 25.1 GW of this capacity could come from gas sources. This dependency on gas highlights a critical juncture for energy policy in the region, as stakeholders must balance the urgent need for power with long-term sustainability goals. The pace at which data centres can be developed—typically within two to five years—contrasts sharply with the longer timelines required for building new generation and transmission infrastructure, which can take five to eight years or more. This mismatch is prompting innovative approaches to capacity allocation and connection strategies. Flexibility in power systems can play a crucial role in mitigating the need for additional capacity. Scenarios that incorporate flexible power generation could reduce the capacity required for data centres from 64.5 GW to 44.4 GW, while also cutting gas consumption by up to 30%. Furthermore, initiatives aimed at regional interconnection could enhance the overall generation mix and lower emissions, making it a strategic priority for governments and energy companies. The ASEAN Power Grid scenario, for instance, could prevent the need for new coal capacity and drastically reduce the demand for battery storage solutions. The growth of data centres also presents a unique opportunity to catalyze investments in renewable energy. Among 100 tracked operators, 53 have set net-zero targets that encompass 69% of their total capacity, indicating a growing commitment to sustainability in the sector. However, translating this demand into tangible renewable energy development will require robust procurement frameworks that can ensure the reliability and credibility of renewable sources. Without these frameworks, the potential for data centres to drive renewable investment may not be fully realized. As the ASEAN region navigates this transformative phase, the interplay between data centre expansion and energy supply will likely become a focal point for both policymakers and business leaders. Companies that proactively engage in developing flexible energy solutions and invest in renewable infrastructure will be better positioned to capitalize on the burgeoning demand for data services. The strategic alignment of energy and digitalisation efforts will not only enhance operational resilience but also contribute to broader sustainability goals. This evolving landscape signals a critical shift in how energy markets will operate, emphasizing the need for integrated planning and collaborative approaches among stakeholders. ## Entities - **Technologies**: digitalisation, hyperscale facilities, gas capacity, renewable energy - **Organizations**: ASEAN ## Key Concepts data centre growth, electricity demand, power capacity, flexibility, regional interconnection, renewable investment, net-zero targets, clean energy procurement ## Definitions - **digitalisation**: The integration of digital technologies into everyday life, which significantly increases electricity demand. - **hyperscale facilities**: Large-scale data centres designed to efficiently manage vast amounts of data and computing power. - **flexibility**: The ability of power systems to adapt to changes in demand and supply, which can reduce capacity requirements. - **net-zero targets**: Commitments made by organizations to balance the amount of greenhouse gases emitted with the amount removed from the atmosphere. - **clean energy procurement**: The process of acquiring energy from renewable sources to support sustainability goals. ## Use Cases - meeting data centre electricity demand - developing data centres within a short timeframe - reducing gas requirements through flexibility - encouraging renewable investment - tracking operators' net-zero targets - implementing credible renewable energy development mechanisms ## Frequently Asked Questions **What is the projected electricity demand from ASEAN data centres by 2035?** ASEAN data centre electricity use could reach between 171 and 258 TWh by 2035, a significant increase from around 20 TWh in 2023. **How much additional power capacity might be needed to support data centre growth?** Meeting the demand from data centres could require an additional capacity of 53.5 to 82.0 GW by 2035, with a significant portion expected to come from gas. **What factors influence the location of data centre growth?** Power availability and connection timelines are crucial, as data centres can be developed quickly, while necessary infrastructure may take longer to establish. **How does flexibility impact capacity requirements for data centres?** Flexibility can significantly lower the capacity needed for data centres, reducing it from 64.5 GW to 44.4 GW and cutting gas requirements by up to 30%. **What role do procurement frameworks play in renewable investment?** Credible procurement frameworks can catalyze renewable investment by translating the demand from data centres into actionable renewable energy development. ## Links - [Read on Welcome.AI](https://welcome.ai/content/asean-data-centres-face-urgent-power-demand-and-capacity-challenges) - [Original source](https://aseanenergy.org/publications/powering-data-centre-growth-in-the-age-of-ai) --- Source: Welcome.AI | https://welcome.ai/content/asean-data-centres-face-urgent-power-demand-and-capacity-challenges
