Construction Timeline and Operational Target for Saguling FPV
92 MW Floating Solar Plant Construction at Saguling Reservoir. PT PLN (Persero), through its subsidiary PLN Indonesia Power, has started building a 92 MWp floating solar photovoltaic (FPV) plant on the Saguling Reservoir in West Bandung Regency, West Java. The project belongs to Indonesia’s National Strategic Projects and aims to accelerate the country’s transition to renewable energy.
The plant will start commercial operations in November 2026 and is projected to generate over 130 GWh of electricity annually. This output can supply power for approximately 24,000 households, significantly strengthening regional electricity security.
Design Considerations and Reservoir Surface Utilization
The installation will cover less than 5% of the reservoir surface to minimize interference with hydropower generation and irrigation. By installing panels on the water surface, the project efficiently generates energy without occupying valuable land.
Key technical features include:
- Floating solar panels reduce overheating and improve efficiency.
- Anchoring systems adapt to water level fluctuations and currents.
- The system integrates seamlessly with the local electrical grid to ensure a stable energy supply.
Environmental Impact and Carbon Emission Reduction
The project reduces approximately 104,000 tons of CO₂ emissions annually. This reduction supports national climate goals and demonstrates Indonesia’s commitment to clean energy adoption.
Additionally, shading from the floating solar panels reduces water evaporation from the reservoir, conserving resources and showcasing the multi-functional benefits of the installation.
Community Engagement and Economic Advantages
The project creates employment opportunities during both construction and operation, benefiting local communities. The improvements in electricity supply support economic activities and encourage local development.
Community-focused initiatives include:
- Training programs for local workers to maintain and monitor solar panels.
- Collaboration with local authorities to perform environmental monitoring.
- Engagement of residents in ecological assessment and stewardship of the reservoir area.
Integration with Indonesia’s Renewable Energy Plan
The Saguling floating solar project contributes to Indonesia’s plan to expand renewable energy capacity to 42.6 GW by 2034, including 17.1 GW from solar energy. By utilizing water surfaces for solar panels, the project avoids land competition and allows scaling to other reservoirs.
This approach strengthens energy security, reduces emissions, and serves as a replicable model for future renewable energy projects in Indonesia.
Project Financing and International Collaboration
The project receives domestic and international investment of around US$60 million, structured to ensure economic viability and long-term sustainability. Local government support facilitates permitting and engages communities to streamline project execution.
Engineering Challenges Unique to Floating Solar
Floating solar systems face challenges different from ground-based installations. Panels must remain stable against water currents and wind while adapting to water level changes without disrupting reservoir operations.
Additional considerations include:
- Maintaining aquatic ecosystems, including fish populations and plant life.
- Preventing water quality issues, such as excessive algae growth near panels.
- Integrating generated electricity efficiently into the regional grid.
Scalability and Replication Potential in Other Reservoirs
The Saguling FPV plant serves as a blueprint for deploying floating solar across other Indonesian reservoirs. By combining clean energy generation with minimal environmental impact, the project demonstrates a sustainable approach that can be replicated nationwide.
