- New JHB3 and JHB4 campuses to add additional 280MW IT load.
- AirTrunk’s Malaysia platform now delivers more than 700MW across four campuses.
- Brings AirTrunk’s total Malaysia investment to approximately USD6.8 billion (MYR27 billion).
- AirTrunk is planning further expansion in Malaysia post JHB3 and JHB4.
AirTrunk, Asia-Pacific and the Middle East’s leading hyperscale data centre platform, has announced plans to invest MYR12 billion (USD3 billion) to develop two new data centres in Malaysia, to be called JHB3 and JHB4. This investment further expands AirTrunk’s footprint in Johor Bahru and reinforces its commitment to Southeast Asia’s rapidly growing digital economy.
Located in Iskandar Puteri in Johor, JHB3 and JHB4 will have a combined capacity of more than 280 megawatts (MW) of IT load and will locate close proximity to its existing JHB1 and JHB2 campuses.
Between the four campuses in Malaysia, AirTrunk will have more than 700MW of IT load, bringing AirTrunk’s total committed investment in Malaysia to approximately MYR27 billion (USD6.8 billion), underscoring the company’s long-term commitment to the region.
These campuses will be purpose-built to support high-density cloud and AI workloads, featuring a flexible, scalable, and resilient design. The designs prioritise energy efficiency, operating at significantly lower power usage levels than conventional data centres. The campuses will also include advanced cooling systems that utilise 100% recycled water, minimising any impact on local resources.
Together, these features position the development to meet the growing demand from global cloud and technology providers, while staying committed to the responsible use of energy and water.
AirTrunk’s current expansion follows its announcement of JHB2 campus in early 2025, which has already garnered strong commitments from its existing global cloud and AI customers. The existing JHB1 and JHB2 campuses (totalling more than 420MW of IT load) are almost 100% contracted and tracking well ahead of investment plans.
AirTrunk is committed to supporting local economy and have already awarded MYR423 million (USD107 million) to local suppliers, and this number is expected to grow to MYR 5 billion (USD1.3 billion) on completion of all four campuses.
This expansion follows AirTrunk’s announcement of entry into India last week, supported by its planned investment of more than USD 5 billion into the Indian market in the near-term.
Robin Khuda, Founder & CEO, AirTrunk, said: “JHB3 and JHB4 represents the next phase of our expansion in Malaysia, building on the strong momentum of our existing Johor platform. Malaysia has set a clear ambition to lead in AI, and we’re investing in that vision for the long term, both within Johor and across the country in time. Our confidence comes from the strong partnership we have with the Malaysian Government and local stakeholders, who have supported us every step of the way. As we scale, the way we grow will matter as much as the trajectory. With that investment comes a responsibility to support communities, manage resources wisely, and embed that in how we plan, build and operate every day.”
YAB Datuk Amar Haji Fadillah bin Haji Yusof, Deputy Prime Minister and Minister of Energy Transition and Water Transformation, Malaysia quote: “Malaysia is committed to strengthening its position as a leading digital and AI hub in the region. Our ambition is to be at the forefront of the digital and AI economy, supported by strong infrastructure, a robust ecosystem and responsible development in digital infrastructure. Investments like AirTrunk’s Johor expansion reflect growing confidence in Malaysia and play an important role in advancing innovation, talent development and long-term economic benefit for both the community and the environment. We welcome AirTrunk’s data centre investment that align with our vision of efficiency, sustainability and the use of clean energy.”
Malaysia is advancing its ambition to become a leading digital and AI hub in the region through a coordinated approach that brings together strong government policy, infrastructure readiness and close collaboration with industry partners. This public–private partnership model is accelerating investment, innovation and the development of a robust digital ecosystem to support long-term, sustainable growth.
Her Excellency Danielle Heinecke, Australia’s High Commissioner to Malaysia, said:
“AirTrunk’s investment is a good example of how Australia and Malaysia are working more closely together in building digital infrastructure. It supports Malaysia’s growth in the digital economy while also strengthening the connection between our two countries.
AirTrunk’s Johor campuses to support local jobs and communities
The development of JHB3 and JHB4 is expected to generate significant economic benefits for Johor and Malaysia, including creating more than 3,000 jobs during construction, ongoing employment to local talent once operational, and partnerships with local suppliers and contractors to support regional industry.
AirTrunk is also committed to supporting local communities through targeted education, digital inclusion and social impact initiatives that build pathways into future careers.
Partnerships include:
- STEM education & Digital Literacy: A collaboration with Universiti Teknologi Malaysia (UTM), providing multi-year STEM scholarships and industry engagement to support pathways into technology and engineering careers. AirTrunk also supported Johor Digital Literacy Day 2025 in partnership with ICDL.
- Water replenishment: Through partnerships with Gravity Water and Water Watch Penang, AirTrunk is delivering sustainable, rainwater-harvesting solutions to provide potable water in schools across Johor Bahru, while advancing education and water stewardship initiatives that support long-term climate resilience.
- Disaster Resilience & Response: Through a partnership with MERCY Malaysia, AirTrunk is supporting flood resilience initiatives in Johor, alongside national disaster response efforts to strengthen preparedness and community resilience across Malaysia.
Post JHB3 and JHB4, AirTrunk will scale to more than over 3.3 GW of operating and planned capacity, across 22 campuses in six operating regions (Australia, Singapore, Japan, Malaysia, Hong Kong, and India) as of today.
