Jakarta, Indonesia — Global solar technology leader LONGi has announced a strategic partnership with Pertamina New & Renewable Energy (Pertamina NRE), the green energy arm of Indonesia’s state-owned energy giant, Pertamina. Together, the two companies will develop a 1.6-gigawatt (GW) solar panel manufacturing facility in West Java, marking a major milestone in Southeast Asia’s renewable energy landscape.
The joint venture aims to boost Indonesia’s solar production capacity, support its clean energy ambitions, and accelerate the region’s shift toward a more sustainable energy future.
High-Tech Solar Manufacturing Hub in West Java
The facility will be located in Deltamas, West Java, and is expected to become operational by mid-2025. Once completed, it will feature an annual production capacity of 1.6 GW and will utilize LONGi’s cutting-edge Hybrid Passivated Back Contact (HPBC) 2.0 technology, which enables the production of high-efficiency solar modules.
This investment underscores Indonesia’s growing appeal as a renewable energy manufacturing base and demonstrates the country’s readiness to play a larger role in global clean energy supply chains.
LONGi: “A Long-Term Commitment to Indonesia’s Green Future”
LONGi Vice President Dennis She emphasized the broader significance of the project beyond its manufacturing scope. “Indonesia holds immense potential in renewable energy, and LONGi is proud to contribute our world-leading solar technology to this transformative journey,” he said.
“This facility represents not just an investment in production, but a long-term partnership aimed at accelerating Indonesia’s clean energy future. By localizing manufacturing, we aim to reduce costs, promote innovation, and create high-value green jobs, reinforcing our commitment to a net-zero world.”
Aligning with Indonesia’s Energy Transition Targets
The announcement comes at a critical time for Indonesia, which has laid out ambitious renewable energy goals in its Electricity Supply Business Plan (RUPTL) 2025–2034. The plan targets the installation of 17.1 GW of new solar PV capacity over the next decade, a major scale-up from current levels.
By establishing domestic solar production capacity, the LONGi–Pertamina NRE partnership aims to play a pivotal role in helping Indonesia meet these targets, while also enhancing energy security and reducing reliance on imported solar technologies.
The new plant will not only serve domestic demand but also supply solar modules to neighboring Southeast Asian markets, positioning Indonesia as a regional manufacturing hub.
Strengthening the Local Renewable Energy Value Chain
The collaboration is expected to have far-reaching effects across the Indonesian renewable energy ecosystem. With localized manufacturing, the initiative will help strengthen the solar value chain, drive the adoption of high-efficiency technologies, and provide momentum to the broader green industrial strategy being pursued by the government.
Pertamina NRE has stated that the partnership reflects its strategic direction toward energy diversification and sustainability. The company continues to explore collaborative opportunities that align with the national goal of achieving net-zero emissions by 2060.
Southeast Asia’s Role in the Global Energy Shift
The move also reflects a growing trend in Southeast Asia, where countries are ramping up investments in renewable energy infrastructure. With this project, Indonesia joins regional peers like Vietnam and Malaysia in advancing solar manufacturing capabilities, aligning industrial development with environmental goals.
As energy demand in the region continues to grow, initiatives like this will be critical in ensuring that future supply is sustainable, affordable, and resilient.
Conclusion
The LONGi–Pertamina NRE solar manufacturing facility is set to become a cornerstone in Indonesia’s clean energy transition. With operations scheduled to begin in 2025, the project not only enhances the country’s solar capacity but also signifies a deepening commitment to a greener, innovation-driven future for Southeast Asia.
