TotalEnergies ENEOS Completes Phase II Expansion of Rooftop Solar in Indonesia: Renewable Energy Demand in Asia-Pacific Manufacturing Accelerates

Event Overview

On June 12, 2026, TotalEnergies ENEOS announced the completion of Phase 2 expansion of the rooftop solar photovoltaic (PV) project at the Ceres chocolate manufacturing plant in Bandung, Indonesia. The project installed approximately 2,400 new solar panels, adding 1.4 MWp of capacity, bringing the total installed capacity to 3.6 MWp.

Project Details

Phase 1 was delivered in September 2024 with an initial capacity of 2.2 MWp. After the completion of Phase 2, the entire system can generate approximately 4,630 MWh of electricity annually, equivalent to meeting about 12% of the plant's electricity demand. TotalEnergies ENEOS, as the long-term Power Purchase Agreement (PPA) counterparty, is responsible for investment, construction, and operation.

Business Significance

For Ceres: Reduces electricity costs through on-site solar generation, hedges against rising industrial electricity prices in Indonesia, and enhances its ESG rating, aligning with global customers' requirements for low-carbon supply chains.

For TotalEnergies ENEOS: Expands its distributed solar portfolio in Southeast Asia and strengthens its position as a provider of commercial and industrial rooftop solar solutions. The project is the latest achievement in the Asia-Pacific region for the 50/50 joint venture between TotalEnergies and ENEOS.

Industry and Trade Impact

Southeast Asia Renewable Energy Market: Indonesia targets a 23% renewable energy share by 2025, but progress has been slow. Commercial and industrial rooftop solar, with advantages such as no need for large-scale land and shorter approval cycles, offers a viable path for rapid decarbonization. Projects like Ceres demonstrate that multinational companies are driving local suppliers to adopt green electricity.

Implications for Australia:

1. Export Opportunities: Australia, with its mature PV technology (e.g., monocrystalline silicon modules) and engineering services, can provide solutions to manufacturing enterprises in Southeast Asia. 2. Critical Mineral Demand: Solar panel manufacturing relies on materials such as lithium and nickel supplied by Australia; regional growth in solar installations will indirectly boost mining demand. 3. Investment Benchmark: Australian funds and infrastructure investors can learn from the TotalEnergies ENEOS model, participating in distributed energy projects in Southeast Asia through PPAs to obtain stable returns.

Future Trends

With the recovery of manufacturing and supply chain restructuring in the Asia-Pacific region, corporate self-use renewable energy will become a standard configuration. The IEA predicts that solar installations in Southeast Asia will grow at an average annual rate of 15% from 2025 to 2030, with commercial and industrial rooftops accounting for about 40%. Australian companies that position themselves early can gain first-mover advantages in technology export, project investment, and carbon services.

Conclusion

TotalEnergies ENEOS's Phase 2 expansion in Indonesia epitomizes the energy transition of manufacturing in the Asia-Pacific region.TotalEnergies ENEOS's second phase expansion in Indonesia is a microcosm of the energy transition in Asia-Pacific manufacturing. For Australian businesses, this not only signifies a new export market for photovoltaic components, but also represents a new investment paradigm: embedding capital and expertise into the decarbonization process of regional supply chains.
