TotalEnergies ENEOS completes Phase 2 rooftop solar expansion at the Ceres factory in Bandung, Indonesia: A new milestone for distributed photovoltaics in manufacturing

Project Overview

In June 2026, TotalEnergies ENEOS announced the completion of the second phase of rooftop solar photovoltaic expansion at the Ceres manufacturing facility in Bandung, Indonesia. The factory, operated by PT. Perusahaan Industri Ceres, is one of Indonesia's leading chocolate and confectionery producers. The second phase added approximately 2,400 solar panels with a capacity of 1.4 MWp, generating over 1,380 MWh annually. Combined with the first phase of 2.2 MWp completed in September 2024, the total installed capacity reaches 3.6 MWp, with an annual generation of about 4,630 MWh, meeting approximately 12% of the factory's total electricity demand.

Financing and Operational Logic of Distributed PV in Manufacturing: Insights from a Single Project

The core of this project lies in its commercial structure: TotalEnergies ENEOS, as a joint venture between TotalEnergies and Japan's ENEOS, undertakes the investment, construction, and operation, while the Ceres factory consumes the generated electricity through a long-term Power Purchase Agreement (PPA). This model is increasingly popular in Southeast Asian manufacturing, especially in emerging markets like Indonesia—companies can access clean electricity without upfront capital expenditure, while locking in long-term electricity prices and hedging against fossil fuel price volatility.

Industrial electricity prices in Indonesia have been trending upward in recent years, and the government is gradually tightening carbon emission regulations. Large manufacturers face ESG pressure from international brand supply chains, making distributed PV one of the most direct ways to reduce Scope 2 emissions. Leveraging its global project development experience and local partner networks, TotalEnergies ENEOS can provide factories with a "zero-investment, low-risk" solution—essentially an extension of Energy-as-a-Service.

Micro-Level Validation of Indonesia's Industrial Energy Transition

Indonesia boasts abundant solar resources, but the penetration of photovoltaics in the industrial sector remains low. According to Indonesia's National Energy Plan, the target for renewable energy share by 2025 is 23%, and current PV installations fall far short of this goal. Industrial rooftop PV, due to its advantages of not requiring land, being close to load centers, and having relatively simple approval processes, has become the fastest-growing market segment in recent years.

The Ceres factory is located in Bandung, West Java—a core area of Indonesia's manufacturing cluster. Bandung and its surroundings attract numerous food, textile, and electronics processing companies, and the grid infrastructure is relatively well-developed, providing ideal conditions for self-consumption distributed PV projects. TotalEnergies ENEOS's decision to expand the second phase here demonstrates its long-term confidence in Indonesia's industrial PV market and validates the feasibility of scalable replication.

Global Energy Giants' Distributed Strategy in Southeast AsiaTotalEnergies ENEOS is a joint venture platform between TotalEnergies and ENEOS, focusing on distributed solar business in the Asia-Pacific region. TotalEnergies, as a French energy giant, is accelerating its transformation from traditional oil and gas to an integrated power company, with distributed photovoltaics seen as a key growth engine for its downstream business. ENEOS is Japan's largest oil refining and energy company, also seeking diversification in renewable energy assets. The joint venture model of the two companies combines European technology and capital advantages with Japan's Asian market network, forming a unique competitiveness in Southeast Asia.

This project is not an isolated case. TotalEnergies ENEOS has deployed multiple industrial rooftop projects in Indonesia, Vietnam, Thailand, etc., covering industries such as automotive parts, electronics, and food processing. Its goal is to reduce unit costs and improve asset utilization through standardized design, long-term operation and maintenance contracts, and digital monitoring. The second-phase expansion of the Ceres factory is a typical manifestation of this strategy: additional investment on the basis of existing cooperation, doubling capacity through existing rooftop space, with lower marginal costs and shorter payback periods.

Regional Power System and Infrastructure Insights

From a broader perspective, the large-scale deployment of distributed photovoltaics will have a profound impact on Indonesia's power system. Indonesia's state-owned electricity company PLN has long monopolized the transmission and distribution network, but in recent years it has allowed private PPAs for self-consumption projects. However, surplus electricity grid injection still faces policy restrictions, and most projects adopt a "full self-consumption" model. This means that the factory's load curve matching with photovoltaic output is crucial. The Ceres factory project covers 12% of electricity consumption, indicating that its production activities are highly correlated with sunlight hours, which may also be a key reason for choosing rooftop PV over other renewable energy sources.

In addition, the "asset-light, service-oriented" model embodied in the project provides a replicable template for the energy transition of Indonesia's small and medium-sized manufacturing industry. In the future, as battery storage costs decline, similar projects can further increase the self-consumption ratio, and even achieve off-grid operation. This has long-term significance for reducing electricity costs for Indonesian manufacturing and enhancing supply chain resilience.

Conclusion

The second-phase expansion of the cooperation between TotalEnergies ENEOS and Ceres, on the surface, is a rooftop PV project for a single factory, but in reality it reflects the continuous inflow of global energy capital into Southeast Asian industrial distributed photovoltaics, the maturation of corporate PPA models, and the rigid demand for green electricity from Indonesia's manufacturing industry. In the eyes of infrastructure investment institutions, such projects have stable cash flows, low credit risk, and the potential for asset portfolio expansion. As Indonesia's industrial electricity demand grows at an average annual rate of over 5%, distributed photovoltaics will become an important infrastructure form supporting industrial growth and decarbonization goals in parallel.
