Indonesia’s Largest Floating Solar Plant Goes Live

Launching Southeast Asia’s Largest Solar Plant

Indonesia has reached a pivotal moment in its renewable energy trajectory with the inauguration of the Cirata floating solar plant, the largest of its kind in Southeast Asia. This significant milestone, marked by the presence of President Joko Widodo, showcases the successful deployment of Sungrow FPV‘s advanced system solution at the 192WMp Cirata hydropower reservoir in West Java. A collaborative endeavor between UAE’s Masdar and Indonesia’s PLN Nusantara Power (PLN NP), the 145MW (192MWp) facility not only stands as a testament to innovative engineering but also as a symbol of the burgeoning partnership between Indonesia and the UAE. Poised to power 50,000 households and significantly reduce carbon emissions, this project represents a leap forward in Indonesia’s journey towards sustainable energy and a cleaner, greener future.

“The Cirata Floating PV project represents a historic milestone in the collaboration between Indonesia and the United Arab Emirates, reflecting our shared vision for a cleaner, greener world,”

Dr. Sultan Al Jaber, UAE Minister of Industry and Advanced Technology and Masdar Chairman.

“The Cirata floating solar plant is a crucial part of this plan that will aid Indonesia in reducing carbon emissions by an estimated 214,000 tonnes annually.”

Historic Inauguration by President Widodo

The inauguration, attended by key figures including President Widodo, highlights the importance of the Cirata project in Indonesia’s renewable energy landscape and its role in achieving net-zero emissions by 2060.

Strategic UAE-Indonesia Collaboration

Masdar, the UAE’s clean energy pioneer, partners with PLN NP, marking its first venture into floating solar PV and Southeast Asia’s renewable energy market. This partnership strengthens bilateral ties and underscores the significance of international cooperation in tackling climate change.

Masdar’s involvement extends beyond Cirata, with investments in geothermal energy and an expanding presence in Southeast Asia. This reflects the UAE’s commitment to supporting regional decarbonization efforts and showcases Masdar’s growing influence in global renewable energy.

Overcoming Environmental Hurdles

The project’s success involved overcoming significant environmental challenges, including deep water, fluctuating water levels, and varying elevations. Through strategic design, material selection, and simulations, the team ensured the stability and durability of the solar plant.

Innovative Engineering in Challenging Terrain

The Cirata project faced unique geographical challenges, necessitating Sungrow FPV’s bespoke high-load-bearing anchor blocks. These tailored solutions effectively countered potential issues like block slippage, enhancing construction efficiency and optimizing water surface utilization.

The design and installation of the Cirata project were rigorously audited by reputable third-party organizations such as DNV, RINA, and INNOSEA, ensuring adherence to the highest safety and quality standards.

Future Prospects and Global Impact

The Cirata floating solar plant is instrumental in Indonesia’s commitment to reducing carbon emissions. It is estimated to cut down 214,000 tonnes of carbon emissions annually, aligning with global sustainability goals.

Sungrow FPV plans to leverage its technological prowess and high-quality services to further the clean energy industry, particularly in regions participating in the Belt and Road Initiative.

Following the successful launch of Cirata, Masdar and PLN NP have announced plans for Phase II, aiming to add up to 500MW more capacity. This expansion aligns with Indonesia’s ambitious renewable energy goals and showcases the potential for further advancements in solar technology.

  • Capacity: 145MW (192MWp)
  • Annual Carbon Offset: 214,000 tons
  • Area Coverage: 250 hectares
  • Phase II Potential: Up to 500MW additional capacity
  • Inauguration Date: November 9, 2023
  • Key Attendees: President Joko Widodo, UAE and Indonesian ministers, Masdar and PLN executives
  • Global Significance: Largest floating solar plant in Southeast Asia


The Cirata floating solar plant by Sungrow FPV not only stands as a testament to innovative engineering in renewable energy but also significantly contributes to Indonesia’s environmental goals. This project highlights progress for the future of clean energy initiatives globally.
