Solar Cell Installation Project for Wastewater Treatment System, Building A

The wastewater treatment system in Building A operates using the Activated Sludge (AS) process, which relies primarily on aeration pumps and water pumps. As a result, the system requires relatively high electricity consumption. To address this, the Company implemented a Solar Cell installation project to supply renewable electricity for the wastewater treatment system. The solar panels were installed on the roof area above the walkway behind the building, with a total installed capacity of 20.74 kW.

Performance Results (February 1 – December 31, 2025)

• The system generated 15,944 kWh of solar electricity to replace electricity from the main grid.
• The estimated full-year performance is expected to reach approximately 17,393 kWh per year.
