PLN Indonesia Power UBP Asam Asam has taken a significant step towards sustainable energy by installing a 15 kW (15,000 Watt) Floating Solar Power Plant (PLTS Apung) at the Asam Asam Coal-Fired Power Plant (PLTU) in Tanah Laut, South Kalimantan.

This initiative underscores the company's commitment to advancing green energy and supporting Indonesia's renewable energy targets.

The floating solar panels are installed on the ash pond of units 3 and 4 at the Asam Asam PLTU. These ponds, currently devoid of coal ash, provide a safe and optimal location for the floating solar system. The electricity generated is utilized to power the administrative buildings of the PLTU, enhancing operational efficiency and reducing reliance on fossil fuels.

Floating solar technology offers several advantages over traditional land-based solar installations. By utilizing existing water surfaces, it conserves land resources and can lead to increased energy production due to the cooling effect of water on the panels, which enhances efficiency. Additionally, the shading provided by the panels reduces water evaporation and can inhibit algae growth, contributing to better water conservation and quality.

However, implementing floating solar systems also presents challenges. The initial investment can be higher due to the need for specialized equipment and materials to ensure durability and resistance to water-related issues. Maintenance can be more complex, requiring regular inspections to address potential problems such as biofouling or structural integrity concerns. Environmental impacts, including effects on aquatic ecosystems, must be carefully assessed to prevent ecological disruptions.

Despite these challenges, the global trend towards floating solar installations is on the rise, with countries like Indonesia investing in such projects to diversify their renewable energy portfolios. Notably, Indonesia inaugurated the Cirata Floating Solar Power Plant, the largest in Southeast Asia, with a capacity of 192 MWp, highlighting the nation's commitment to large-scale renewable energy projects.

PLN Indonesia Power's initiative at the Asam Asam PLTU serves as a model for integrating renewable energy solutions into existing infrastructure. By repurposing unused water surfaces for solar energy generation, the company demonstrates innovation in addressing space constraints and environmental concerns associated with traditional solar farms.

This project aligns with Indonesia's broader goals of increasing the share of renewables in its energy mix and reducing greenhouse gas emissions. As the country continues to develop its renewable energy sector, initiatives like the Asam Asam floating solar plant contribute to sustainable development and energy security.

In conclusion, the 15 kW floating solar installation by PLN Indonesia Power UBP Asam Asam represents a forward-thinking approach to renewable energy adoption. By leveraging floating solar technology, the company not only enhances its operational sustainability but also sets a precedent for similar projects in the region, supporting Indonesia's transition towards a greener energy future.
