Pertamina & LONGi Launch 1.4 GW Solar PV Module Factory in Indonesia

Taking Indonesia’s energy transition a significant step ahead, the State energy company Pertamina New & Renewable Energy (Pertamina NRE), in partnership with LONGi Green Technology Co., Ltd., launched a solar panel manufacturing project in Deltamas, West Java, on Monday, June 23, 2025.

The Deltamas facility will manufacture high-efficiency photovoltaic (PV) modules with a target annual capacity of 1.4 GW. The modules will be based on LONGi’s cutting-edge HPBC 2.0 N-type technology.

“This project will significantly support Indonesia’s energy transition roadmap, which targets a 34.3 percent renewable energy mix by 2034,” Eniya Listiani, Director General of New, Renewable Energy, and Energy Conservation (EBTKE), the Ministry of Energy and Mineral Resources (ESDM), said while addressing at the launch event on Monday.

“We hope this project progresses smoothly to support the National Electricity Supply Plan (RUPTL), aiming for an additional 69.5 GW of capacity, of which 61 percent − or 42.6 GW − should come from renewable sources,” she added.

The new solar module facility is located in the industrial zone of Deltamas in Indonesia. It aims to strengthen domestic PV supply chains, reduce production costs, and create skilled green jobs. The initiative aligns with the government’s commitment to boost local content (TKDN) and scale up Indonesia’s renewable energy manufacturing capacity.

Building National Capabilities

Notably, Indonesia has a current domestic solar panel production capacity of 1.6 GW per year. With this project, it is set to increase to over 3 GWp. This will form a key foundation for Indonesia’s long-term target of adding 300-400 GWp of solar power by 2060, according to the Ministry of Industry.

Deputy for Investment Implementation Control at the Investment Ministry/Investment Coordinating Board (BKPM), Edy Junaedi, praised the collaboration, suggesting that the project not only enhances Indonesia’s manufacturing capabilities but also positions the country within the global renewable energy supply chain.

John Anis, CEO of Pertamina NRE, said “By building local manufacturing capacity, we aim to secure domestic PV supply, reduce production costs, and generate green jobs.” He highlighted that the project represents a crucial milestone

LONGi is renowned for its solar PV technology. In the 2025 PV Module Reliability Scorecard, LONGi recently secured the Top Performer designation in the 2025 PV Module Reliability Scorecard based on its results in critical tests including TC (Thermal Cycling), MSS (Mechanical Stress Sequence), PID (Potential Induced Degradation), LID+LETID (Light Induced Degradation and Light and Elevated Temperature Induced Degradation), and PAN File (Simulation Data File Performance).
