ST Telemedia Global Data Centers (STT GDC) has secured up to $1.37 billion in green financing for its Johor data center campus in Malaysia. The funding will support the first 16MW phase of STT Johor 1, with construction expected to finish in 2027. The wider project has a planned capacity of 166MW, according to Data Center Dynamics. The scale of the development highlights Johor’s growing role in Southeast Asia’s data center market.

Green Financing Supports STT Johor’s First Phase

STT GDC broke ground on STT Johor 1 in February 2025. The company had announced the new Johor campus in November 2023 as part of its expansion in Malaysia. The site covers about 22 acres within Nusa Cemerlang Industrial Park in Iskandar Puteri, southern Johor. The location gives STT GDC room to build a large-scale campus close to Singapore.

The first building will provide 16MW of IT capacity. That facility will form the opening stage of the wider campus development. STT GDC’s Johor materials identify 120MW of development potential at the campus, while the latest DCD report puts the broader project at 166MW. Capacity figures can change as developers refine campus plans and future phases.

The financing gives STT GDC a substantial capital base for the first stage of construction. Data centers require significant spending on buildings, electrical systems, cooling, connectivity and supporting infrastructure. Green financing also gives the project a stronger link to sustainability-focused capital markets. That combination matters as investors increasingly examine the energy and environmental impact of large digital infrastructure projects.

Johor Strengthens Its Link With Singapore

STT Johor sits about 15 kilometers from Singapore. That proximity gives the campus access to one of Asia’s most important digital infrastructure markets without placing the entire development inside the city-state. STT GDC also plans connectivity with STT Singapore 5, which serves as a regional interconnection hub. The arrangement can help customers connect Johor capacity with Singapore’s wider digital ecosystem.

Johor has attracted growing attention from data center operators because of its location, available land and expanding infrastructure base. Singapore remains a major regional technology and connectivity hub, but land and power constraints have increased the importance of nearby markets. Johor can offer additional space for large facilities while keeping customers close to Singapore. STT GDC’s investment adds another major capacity build to that regional shift.

The location also gives the project a broader strategic role. Customers can use Johor for workloads that require substantial physical capacity while maintaining access to regional networks. That makes the campus relevant to cloud providers, hyperscale operators and businesses with growing compute requirements. The value of the site therefore extends beyond its available megawatts.

Campus Targets High-Performance Computing

STT GDC has positioned the Johor campus to support hyperscale and high-performance computing requirements. The company also highlighted future demand from AI and visual computing when it announced the project. In 2023, the company said, “We are excited to embark on this new phase of our growth. Our establishment of a second data centre campus in Malaysia underscores our unwavering commitment to advancing the country’s digital transformation.” The statement set the strategic direction for the company’s expansion beyond its existing Malaysian footprint.

STT GDC also said, “Our expansion into Johor is a natural step forward as we deliver vital digital infrastructure services that not only meet the surging and ever-evolving demands of our customers for complex design and scalability, but also anticipate future needs, particularly high-performance computing workloads for AI and visual computing.” The statement is increasingly relevant as AI workloads place new demands on data center design. Operators now need to plan for higher rack densities, greater power requirements and more demanding cooling systems. Johor gives STT GDC a platform to address those requirements at scale.

The company’s current Johor information highlights support for high-power-density deployments. The site can support workloads requiring up to 10kW per rack without supplemental cooling under its stated configuration. That capability provides an important foundation for customers running more demanding computing environments. It also shows why the campus can serve workloads beyond traditional enterprise colocation.

Financing Reflects Growing Data Center Investment

The $1.37 billion financing package is significant because data center projects require capital long before they generate operating revenue. Developers must secure land, power connections, buildings, cooling equipment and network infrastructure during the construction cycle. Large financing packages can help operators maintain development momentum while reducing pressure on their own balance sheets. Green financing adds another layer by connecting capital allocation with sustainability objectives.

STT GDC has used sustainable financing across its broader portfolio. The company has developed financing structures that connect its funding strategy with environmental and sustainability targets. That approach has become increasingly relevant across the data center sector as electricity consumption and infrastructure emissions attract greater attention. For investors, the financing structure can provide a clearer framework for assessing the sustainability profile of large digital assets.

The Johor financing also signals lender confidence in Malaysia’s data center growth story. Capital providers must assess expected customer demand, power availability, connectivity and long-term market conditions before backing projects of this size. Johor’s proximity to Singapore strengthens that investment case. The campus can therefore benefit from both Malaysia’s available development capacity and Singapore’s established digital economy.

STT GDC Expands Its Malaysian Footprint

STT Johor forms part of STT GDC’s wider Malaysian expansion. The company has data center operations and projects across Johor, Cyberjaya and Kuala Lumpur. Its Malaysian portfolio includes more than 130MW of IT load across three locations, according to the company. STT GDC entered Malaysia through its partnership with Basis Bay before announcing the Johor campus as its second major Malaysian data center platform.

The expansion gives STT GDC a stronger position in a market that continues to attract global digital infrastructure investment. Malaysia has become an important destination for cloud and data center development in Southeast Asia. Johor offers a particularly attractive location because of its direct relationship with Singapore. STT GDC can use that geographic advantage as it expands its regional capacity strategy.

STT GDC’s broader ownership structure also provides context for its expansion plans. KKR and Singtel completed their acquisition of STT GDC in February 2026 at an enterprise value of S$13.8 billion. The transaction placed the data center operator within a larger investment structure focused on digital infrastructure growth. That backdrop supports the company’s ability to pursue capital-intensive projects across its markets.

STT Johor Moves Toward 2027 Delivery

The immediate focus now turns to the first 16MW phase of STT Johor 1. STT GDC expects construction to reach completion in 2027. The company must now convert the financing commitment into physical infrastructure, power capacity and operational readiness. Customer demand will determine how quickly the initial capacity moves from construction into commercial use.

The wider campus provides room for future expansion as demand develops. AI workloads could increase the need for higher-density facilities across Southeast Asia. Cloud providers and hyperscalers also continue to seek locations that combine power, connectivity and expansion capacity. Johor offers those characteristics while remaining close to Singapore’s established network ecosystem.

The project also highlights how the regional data center market is changing. Operators are competing on more than available capacity, with power resilience, construction speed, connectivity and sustainability becoming equally important. STT GDC’s financing strategy addresses several of those requirements through one major development. The Johor campus could therefore become an important part of the company’s regional growth strategy.

STT Johor’s significance ultimately rests on the combination of capital, location and future capacity. The $1.37 billion financing gives STT GDC substantial support for the project’s initial development. Its proximity to Singapore gives the campus access to a major regional technology hub, while its larger development potential creates room for future growth. For Malaysia, the project strengthens Johor’s position as a major destination for next-generation digital infrastructure.
