Java: Largest Hybrid Solar Plant Project Taking Root
Indonesia’s push towards a greener industrial sector is taking a significant leap forward. In a landmark collaboration, PT iForte Energi Nusantara (iForte) is partnering with PT Steel Pipe Industry of Indonesia Tbk (SPINDO) to develop what is set to be Java’s largest hybrid on-grid solar power plant, complete with an integrated battery storage system. This project marks a pivotal moment for sustainable manufacturing in the region, promising enhanced energy reliability and a reduced carbon footprint.
Project Specifications: Powering a Greener Future with Java hybrid solar plant
At the heart of this initiative is a powerful combination of solar generation and energy storage. The project will feature a solar power plant with a capacity of 6.3 MWp (megawatt-peak). This substantial solar array will be paired with a 1 MWh Battery Energy Storage System (BESS).
The inclusion of the BESS is a critical component that sets this project apart. It allows excess energy generated during peak sunlight hours to be stored and deployed when sunlight is low or during periods of high demand from SPINDO’s steel manufacturing operations. This hybrid on-grid system ensures a stable, reliable, and continuous power supply, which is essential for heavy industry.
While the primary announcement confirms the 6.3 MWp target, some reports have mentioned a capacity of 5.4 MWp. This may reflect a phased rollout or evolving project details, but the goal remains to establish the largest facility of its kind in Java.
A Strategic Partnership for Sustainable Industry with Java hybrid solar plant
This ambitious project is built on a strategic partnership that makes clean energy more accessible. iForte is implementing a zero-CapEx (Capital Expenditure) model, which means SPINDO does not need to make an upfront investment in the solar infrastructure. Instead, the project is financed through green funding, and the cost savings from the solar energy are shared between the partners. This innovative financial model removes significant barriers to renewable energy adoption for industrial clients.
For SPINDO, a leading steel pipe manufacturer, this initiative builds upon its existing commitment to sustainability. The company already operates 2.1 MWp of rooftop solar installations across its facilities (Units 1, 2, and 3), which have been operational since 2025. The new, larger hybrid plant will dramatically increase its reliance on clean energy, furthering its green transition goals.
The Broader Impact on Indonesia’s Energy Landscape: Java hybrid solar plant
The iForte-SPINDO project is more than just a single power plant; it’s a blueprint for the future of Indonesia’s industrial sector. By demonstrating the viability and benefits of large-scale hybrid solar systems, it encourages other manufacturers to invest in renewable energy solutions.
This development directly supports Indonesia’s national goals to reduce greenhouse gas emissions and increase the share of renewables in its energy mix. For the manufacturing sector, it offers a clear path toward greater energy independence, operational efficiency, and long-term cost stability, all while contributing to a healthier environment. As this pioneering project moves forward, it will undoubtedly serve as a powerful catalyst for a cleaner, more sustainable industrial revolution across Java and beyond.
