In a major development for Southeast Asia’s renewable energy landscape, global solar giant LONGi has officially launched a strategic solar panel manufacturing project in Indonesia. In partnership with Pertamina New & Renewable Energy (Pertamina NRE), a subsidiary of the Indonesian state-owned energy firm Pertamina, the initiative marks a significant milestone in accelerating the region’s transition to clean energy.
The state-of-the-art facility will be located in Deltamas, West Java, and is expected to feature an impressive annual production capacity of 1.6 GW. It will deploy LONGi’s latest Hybrid Passivated Back Contact (HPBC) 2.0 technology, enabling the production of high-efficiency solar modules aimed at meeting the surging demand in both domestic and regional markets.
This manufacturing initiative aligns closely with Indonesia’s ambitious renewable energy roadmap outlined in the national electricity supply business plan (RUPTL) for 2025–2034, which targets 17.1 GW of new solar PV installations over the next decade. The collaboration between LONGi and Pertamina NRE not only addresses this projected growth but also reinforces the government’s push to increase local content known as the Domestic Component Level (TKDN) in energy projects.
By boosting local manufacturing capacity, the project will contribute significantly to Indonesia’s renewable energy supply chain. It is also expected to create a multitude of green jobs, strengthen local industry, and reduce dependence on imported solar technology.
“The commencement of the RUPTL project comes at an opportune moment,” said a Pertamina NRE spokesperson. “This partnership will improve the local PV industry chain, help meet the regional demand, and raise the level of localised solar module production, ensuring sustainable industry growth.”
Dennis She, Vice President of LONGi Group, highlighted the long-term strategic value of the project during the launch event. “Indonesia holds immense potential in renewable energy, and LONGi is proud to contribute our world-leading solar technology to this transformative journey,” she said. “This facility represents not just an investment in manufacturing but a long-term partnership to accelerate Indonesia’s clean energy future.”
He further emphasised that by localising production, LONGi aims to reduce costs, spark innovation, and generate high-value employment. “It’s part of our commitment to building a net-zero world and supporting national ambitions in energy transition.”
With this launch, Indonesia is poised to strengthen its role as a key player in the Southeast Asian green energy space. LONGi, known for its technological leadership and global scale, brings crucial capabilities that will benefit the Indonesian market and its neighbouring economies. The facility will cater to rising demand for advanced PV modules across the region, making Indonesia a strategic manufacturing hub.
The move comes as part of LONGi’s broader mission to foster global decarbonisation through innovation and strategic partnerships. The company’s growing footprint in Southeast Asia demonstrates its confidence in the region’s market potential and its alignment with global net-zero goals.
As preparations for manufacturing commence by June 2025, the LONGi-Pertamina NRE collaboration sets a high benchmark for future clean energy partnerships in the region. The integration of advanced solar technology with strong local engagement offers a sustainable blueprint for other countries aiming to bolster their renewable energy infrastructure.
