Perum Jasa Tirta II Aims to Optimise Floating Solar Power Plants to Strengthen Energy Resilience
In an effort to strengthen national energy resilience, Perum Jasa Tirta II (PJT II) is promoting the optimisation of solar power plant (PLTS) development as part of the transition to new renewable energy (EBT).
PJT II’s President Director, Imam Santoso, stated that this step is a strategic initiative to reduce dependence on fossil fuels while strengthening a sustainable and environmentally friendly national energy system.
"The development of PLTS is a concrete step in optimising the water resource potential managed by PJT II, while supporting national energy diversification," Imam said in an official statement on Thursday (16/4/2026).
"PJT II has significant potential in new renewable energy development, including through the utilisation of reservoir areas for floating PLTS," he continued.
In the short term, PLTS development can focus on optimising existing potentials, including the development of floating PLTS in strategic reservoirs and increasing the capacity of operational power plants.
Meanwhile, in the medium to long term, PJT II can optimise the strengthening of its clean energy portfolio through the integration of various EBT sources, including solar, water, and other energy potentials.
"PLTS development is an important part of the national energy transition journey, so PJT II is ready to collaborate so that PLN can continue to expand EBT-based power plant capacity, while ensuring the reliability of the electricity system remains maintained," he said.
Although it has great potential, PLTS and EBT development is not without several challenges, ranging from technical aspects, investment, to integration into the national electricity system.
Some challenges faced include the variability of solar energy sources, the need for supporting infrastructure, and relatively large project financing that requires several strategies, including strengthening cross-sector collaboration, utilising the latest technology, and improving operational efficiency of power plants.
"We will strive to continue strengthening coordination with various stakeholders and adopting adaptive technology to address EBT development challenges," he stated.
"This is important so that field implementation can run effectively and sustainably," Imam added.
This includes strengthening operational monitoring systems, enhancing human resource capacity, and comprehensive risk management. In addition, synergy between water resource management and electricity generation is key to maintaining a balance between energy needs and environmental sustainability.
"Collaboration between PJT II and PT PLN-NP is an important part in building a reliable energy ecosystem. With this synergy, we will support national energy resilience sustainably," emphasised Ruli.
