The Mainland / Digital & Data
Digital & Data
The digital infrastructure district — operated through the MTC-DataCentre-X SPV — occupies a strategically critical position in the mainland ecosystem. Data centres generate the cooling water demand that drives desalination at scale, and their waste heat feeds directly into the brine valorisation crystallisation process. Digital infrastructure is not a standalone investment: it is the load anchor that makes the entire water-minerals circular economy viable.
Hyperscale Data Centres: 150–200MW
The hyperscale data centre campus is designed for a total capacity of 150–200MW, powered entirely by geothermal electricity. This positions the facility among a small global cohort of truly renewable hyperscale operations — with no reliance on renewable energy certificates or power purchase agreements that merely offset fossil fuel consumption elsewhere. The geothermal source provides genuine 24/7 baseload clean power.
Southeast Asia's digital economy is among the fastest-growing in the world, with cloud adoption, AI inference workloads, and enterprise data sovereignty requirements driving unprecedented demand for colocation capacity. Indonesia alone is projected to require significantly more data centre capacity over the coming decade than its current national infrastructure can supply. The Mentawai mainland district addresses this gap with a facility that offers renewable power credentials, competitive tariffs, and HVDC connectivity to Singapore's internet exchange infrastructure.
The campus is designed to consume approximately 12,500 cubic metres of cooling water per day at full load. This demand is met entirely by the desalination plant, creating the primary justification for desalination at scale and, by extension, for the brine valorisation mineral processing operation downstream.
Boutique Data Centres: 20–30MW Ultra-Premium
Alongside the hyperscale campus, the MTC-DataCentre-X SPV operates a boutique data centre offering designed for clients requiring ultra-low latency, high redundancy, and sovereign data residency assurances that hyperscale shared environments cannot provide. This 20–30MW facility targets financial services firms, healthcare operators, government agencies, and AI research institutions where performance and compliance requirements justify premium pricing.
The boutique facility leverages the same geothermal power infrastructure and HVDC fibre connectivity as the hyperscale campus, with dedicated physical separation, enhanced physical security, and bespoke SLA frameworks. Waste heat from both facilities is channelled to the brine crystallisation units, ensuring that the thermal energy released by server operations contributes to mineral production rather than being discharged as an environmental cost.
The Ecosystem Role of Digital Infrastructure
The data centre district illustrates the ecosystem logic of the mainland district at its most elegant: digital infrastructure creates cooling demand, cooling demand justifies desalination, desalination creates brine, brine becomes pharmaceutical minerals and agricultural fertilisers, and waste heat from servers reduces the energy cost of mineral crystallisation. A data centre that might otherwise be criticised as an energy-intensive industry becomes, in this context, the load anchor for a circular economy in water and minerals. That integration is the difference between industrial co-location and a genuinely engineered ecosystem.
