The development of this first data centre campus in Johor, which can be expanded in phases, demonstrates our ability to scale quickly in markets that are important to our customers. With our joint industry expertise and strong track record, we will build and operate one of the most efficient, sustainable and connectivity-rich data centres in Malaysia. In addition to data centres, we will be expanding the submarine cable connectivity between Singapore and Johor to enhance digital connectivity. Our joint venture will also partner institutes of higher learning in Malaysia to nurture talent for our projects and the industry. Our strategy of developing data centre sites with close proximity to our operations in Singapore allow us to capture spill-over demand from our customers and help them scale their business with confidence.” Located in Iskandar Puteri, just 16 km from Singapore, the data centre campus will be the largest to date for both TM and Nxera. It will be built to the latest standards for reliability, security and sustainability while offering the best local and international connectivity. With its close proximity to subsea cable links between Singapore and Malaysia, the data centre will be well-placed to support the increasing demand from both countries’ digitalisation and development initiatives. The initial phase of the data centre is planned for 64MW and can be scaled up to 200MW in response to market demand. This high-power density campus will be able to host large computing and AI capabilities such as requirements by cloud hyperscalers, GPU-as-a-Service providers and features advanced technologies such as liquid cooling to support high-power density workloads and operations efficiently. The data centre will be a LEED-certified (Leadership in Energy and Environmental Design) green building, emphasising its commitment to greater energy efficiency and sustainable practices. As Malaysia’s integrated telco and technology leader, TM will contribute its expertise in the region’s network infrastructure deployment to deliver customised range of wholesale data, connectivity, data centre and platform solutions catering to both local and international needs. Additionally, TM also provides Cloud services via its sovereign Cloud Alpha Edge solution. TM currently operates seven data centres across Malaysia with 2 core data centres located in Klang Valley and Johor. Its entry into the Asia Link Cable Systems (ALC) partnership facilitates the laying of a submarine cable system spanning approximately 7,200km, with an initial design capacity of 24 Terabits/sec. Coupled with the establishment of an international Cable Landing Station at TM Exchange Kuala Sedili, Johor, these serve as vital infrastructure enhancements to accelerate the growth of the data centre industry in the state. Nxera is a rapidly growing regional platform backed by Singtel and leading global investment firm KKR, leveraging its data centre operations in Singapore to expand overseas. Customers can also tap into a host of services such as Singtel’s Paragon cloud orchestration platform and upcoming GPU-as-a-Service. They will be able to orchestrate their AI workloads in a multi-network and multi-cloud environment, serving as a catalyst for greater innovation, entrepreneurship and business excellence. Nxera is developing three new AI-ready data centres in the region in addition to 62MW of existing capacity in Singapore.
