KAI Installs 113 Solar Power Systems Across 92 Locations, Accelerating Clean Energy Transition
Amidst the growing national energy demand, sustainability has become increasingly intertwined with corporate operations. Energy is now viewed not only as an operational necessity but also as an integral part of environmental responsibility. This perspective has driven PT Kereta Api Indonesia (Persero) to continuously expand its utilization of new and renewable energy by developing Solar Power Systems (PLTS) across various corporate operational facilities.
This initiative began in 2022 and has progressed alongside KAI's commitment to supporting the national clean energy transition agenda. As of June 2026, KAI has deployed 113 solar power units with a total installed capacity of 4,430.65 kWp spread across 92 locations. These installations are situated in 62 stations, 10 workshops (balai yasa), 6 employee training and welfare centers (griya karya), 3 depots, 1 office, and 1 record center building, all supporting the company’s operational activities across various regions in Indonesia.
The utilization of solar energy is part of an ongoing transformation across multiple sectors, including transportation. As a company managing large-scale public mobility, KAI views more efficient and low-emission energy consumption as a vital step to support corporate growth while strengthening its contribution toward national environmental targets.
KAI's Vice President of Corporate Communication, Anne Purba, stated that the development of solar power systems is being carried out progressively, taking into account operational needs and the potential for solar energy utilization across various corporate assets.
"The development of solar power systems is part of KAI's efforts to increase clean energy utilization within the company's operations. We continue to expand this program gradually, in line with the company's commitment to sustainability and energy efficiency,"
According to various technical studies on solar energy utilization in Indonesia, every 1 kWp of a solar power system can generate an average of approximately 1,300 to 1,500 kWh of electricity per year, depending on solar irradiance and installation site conditions. With an installed capacity of 4,430.65 kWp, the solar power systems developed by KAI have the potential to produce around 5.8 million to 6.6 million kWh of clean electricity annually.
This energy production delivers quantifiable environmental benefits. The emission reduction calculation refers to the Decree of the Minister of Energy and Mineral Resources No. 163.K/HK.02/MEM.S/2021 regarding the Determination of Grid Emission Factors, which serves as the national benchmark for calculating power sector emissions. Under this regulation, the emission factor for the Java-Madura-Bali (Jamali) interconnected system ranges between 0.84–0.87 tons of CO₂ per MWh.
With an installed capacity of 4,430.65 kWp and an annual electricity production potential of 5.8 million to 6.6 million kWh, KAI's solar power installations have the potential to reduce carbon emissions by approximately 5,100 to 5,800 tons of CO₂ per year. This figure is derived from the estimated annual solar electricity production multiplied by the Jamali grid emission factor established by the Ministry of Energy and Mineral Resources.
These figures demonstrate that solar energy utilization contributes directly to greenhouse gas emission reduction efforts. Every kilowatt-hour of electricity generated by solar power replaces a portion of the electricity demand sourced from fossil-fuel-based power plants, thereby supporting the national low-carbon development agenda.
Beyond generating clean energy, the implementation of solar power also strengthens KAI’s commitment to Environmental, Social, and Governance (ESG) principles. Solar energy utilization fosters energy efficiency, enhances energy resilience at operational facilities, and expands the use of renewable energy sources across the corporate environment.
Currently, solar panels installed at various stations, workshops, depots, and other operational facilities have become a seamless part of the company's daily activities. Their presence demonstrates how technological innovation can align with public service needs and long-term environmental management.
"The transformation toward sustainable transportation requires consistent action. KAI will continue to develop various initiatives that support energy efficiency, emission reduction, and the creation of sustainable value for society and the environment,"
