Jakarta, INTI - Wings Group installed rooftop solar power plants (PLTS) with a total capacity of 36 megawatts peak (MWp) at eight factories in Jakarta, West Java, and East Java. Calculations indicate that these installations are projected to reduce emissions by more than 50,000 tons of CO2 per year, equivalent to planting approximately 2 million trees.
The energy generated by the panels is directly used for factory operations. This model is common in rooftop PLTS systems, where electricity is produced and consumed on the same site. This helps the factories to reduce dependence on external power supplies.
Indonesia’s Solar Energy Capacity
Wings Group's move comes amid Indonesia's efforts to optimize solar energy. Data from the Ministry of Energy and Mineral Resources (ESDM) indicates that the national solar power potential reaches 3,295 gigawatts (GW), while utilization by mid-2025 is only around 538 megawatts (MW). The gap demonstrates both the significant potential for development and the challenges in the implementation.
Global trends are also strengthening the utilization of solar energy. The International Renewable Energy Agency notes that the cost of utility-scale solar power generation has fallen by around 90 percent since 2010. Meanwhile, the Institute for Energy Economics and Financial Analysis projected that Indonesia will need to add around 75 gigawatts of renewable energy capacity by 2040, with solar power being the primary contributor.
Within a broader policy framework, the Climate Action Tracker noted Indonesia's plan to increase the share of renewable energy in its on-grid electricity system to around 44 percent by 2030 and achieve a net-zero emissions target by 2050. These targets underscore the need to accelerate the adoption of clean energy, including in the industrial sector.
On the implementation side, the financing model is a determining factor. SUN Energy offers a zero-investment scheme, with the flexibility of on-grid, off-grid, and hybrid systems. This approach allows industry players to adopt PLTS without the pressure of large upfront capital expenditures, while still achieving energy efficiency.
Wings’ Efforts in Utilizing Sustainable Energy
Wings Group Director, Ricky Tjahjono, described the installation of rooftop PLTS as part of the company's sustainability efforts. He also announced plans to continue similar investments in other facilities, as the industry's focus on energy efficiency and emissions reductions grows.
The eight factories selected in the initial phase were deemed technically and operationally ready. The factories produce a variety of categories, from food and beverages to household and personal care products. Their designation as pilot projects demonstrates a gradual approach before broader expansion.
The company plans to expand the installation of rooftop PLTS to 12 other factories this year. If realized, solar energy capacity in the industrial sector has the potential to increase, although its contribution to national energy needs remains to be seen on a broader scale.
The installation of the rooftop PLTS does not necessarily alter the entire industrial energy landscape. However, it indicates that some energy needs are starting to be met from renewable sources at the production sites.
Conclusion
Wings Group installed rooftop PLTS with a total capacity of 36 MWp at eight of its factories in Jakarta, West Java, and East Java as part of its sustainability and energy efficiency efforts. The installations are projected to reduce emissions by more than 50,000 tons of CO2 per year. Wings' move comes amid Indonesia's efforts to optimize solar energy, increase the portion of renewable energy, and achieve net-zero emissions. Wings plans to expand the installation of rooftop PV plants to 12 other factories this year, indicating the increasing use of renewable energy in the industrial sector.
