Portfolio

The Mentawai One portfolio is organised across three tiers: districts (functional zones within the SEZ), assets (individual operations and facilities), and SPVs (special purpose vehicles that hold and manage specific investments).

SEZ Padang Extension

A 500–600 hectare special economic zone extension designed as a deliberately integrated industrial ecosystem, anchored by geothermal energy and linked through circular material flows.

Siberut Conservation Zone

The conservation heartland of the programme: Siberut Island's national park and surrounding forests, targeted for expansion from 48% to 85% protected coverage through industrial funding.

Geothermal Power Plant

A 150–200 MW geothermal facility providing baseload renewable energy for the entire SEZ at significantly below grid cost, with waste heat feeding downstream brine crystallisation processes.

Energy

Hyperscale Data Centre

A 50–75 MW hyperscale data centre powered entirely by geothermal energy, with cooling water requirements driving the co-located desalination plant.

Technology

Desalination & Water Treatment

Seawater desalination producing fresh water for the data centre and industrial processes, with concentrated brine directed to the mineral extraction facility.

Water Infrastructure

Brine Valorisation Facility

A zero-liquid-discharge facility that extracts pharmaceutical salt, magnesium compounds, potassium sulphate, and lithium carbonate from desalination brine.

Mineral Processing

Geothermal Energy SPV

Special purpose vehicle for the development and operation of the 150–200 MW geothermal power plant anchoring the SEZ Padang Extension.

Energy

Data Centre Operations SPV

Special purpose vehicle for the hyperscale data centre, powered by geothermal energy and cooled by desalinated seawater.

Districts

Functional zones within the SEZ — Energy, Water and Minerals, Advanced Manufacturing, Digital and Finance, Agriculture, and Logistics.

Assets

Individual operations and facilities — geothermal plants, data centres, desalination, brine processing, HVO production, and more.

SPVs

Special purpose vehicles that hold and manage specific investments within the portfolio.
