en.Wedoany.com Reported - On June 8, TotalEnergies ENEOS announced the completion of the second phase of a rooftop solar project in Bandung, Indonesia, in collaboration with PT. Perusahaan Industri Ceres. This phase added approximately 2,400 solar panels and 1.4 MWp of on-site solar capacity, bringing the total rooftop solar capacity at the Ceres Bandung manufacturing facility to 3.6 MWp.
The first phase of the project, with a capacity of 2.2 MWp, was delivered in September 2024. Following this expansion, the entire system is expected to generate approximately 4,630 MWh of clean electricity annually, covering about 12% of Ceres' electricity demand.
Ceres is a major chocolate and confectionery manufacturer in Indonesia, with a manufacturing base that requires continuous and stable electricity demand, placing high importance on electricity costs, supply reliability, and a low-carbon manufacturing image. This rooftop solar expansion adopts a long-term power purchase service model, where TotalEnergies ENEOS is responsible for development, financing, construction, and operation. Ceres does not bear upfront capital expenditure and only pays for the renewable electricity actually generated by the system. For food processing and confectionery factories, the advantage of rooftop solar lies in its direct integration into existing factory space without requiring additional large industrial land, while also enabling on-site consumption of some electricity during peak daytime production hours, reducing reliance on the conventional grid. The second-phase expansion of the Bandung project advances a single demonstration rooftop plant into a continuously scalable factory energy solution, indicating that Indonesian manufacturing companies are incorporating distributed solar into long-term cost reduction and emission reduction tools, rather than merely treating it as a corporate social responsibility showcase project.
Indonesia's manufacturing sector is widely distributed, with abundant factory rooftop resources. Industries such as food and beverage, textiles, electronics, packaging, rubber, ceramics, and chemicals all have conditions for developing commercial and industrial distributed solar. Compared to large-scale ground-mounted power plants, rooftop solar projects are typically smaller in scale but offer faster deployment, shorter grid connection paths, and higher on-site consumption rates, providing more direct benefits to industrial customers. The second phase of the Ceres project adds approximately 1,380 MWh of annual electricity generation. Combined with the first phase, it can establish a stable daytime clean electricity source at the factory level and mitigate some impacts of electricity price fluctuations. For TotalEnergies ENEOS, this project continues its expansion path in the Asian commercial and industrial distributed energy market, with business focus concentrated on factory rooftop resource assessment, structural safety, panel layout, inverter systems, generation monitoring, long-term operation and maintenance, and customer energy optimization.
Future variables will focus on the system's long-term generation performance, factory load matching, rooftop expansion potential, and Indonesia's commercial and industrial solar policy environment. If this model operates stably at the Ceres manufacturing base, similar food processing, daily chemical, packaging, and light manufacturing companies may continue to adopt the "third-party investment and construction + long-term corporate power purchase" approach to advance factory energy transformation. For Indonesia, although individual distributed solar projects are small in scale, the simultaneous deployment across numerous factories can increase the share of renewable energy use without significantly increasing land pressure, while promoting a clearer low-carbon electricity source for the manufacturing supply chain.
