The Terra Solar Project is developing a 500kV Transmission Line over a 13 km route with 89 towers, utilizing 4-410 mm² Thermal Resistant Aluminum Alloy Conductors Steel Reinforced (TACSR) per phase. This line will initially connect to the existing 500 kV Nagsaag-San Jose NGCP Transmission Line and eventually link to the upcoming 500 kV Nagsaag-Marilao Transmission Line. The project also involves constructing a 500kV/230kV Main Substation, a 230 kV/34.5 kV Main Collector Substation, and two 230 kV/34.5 kV PV Satellite Substations, which are critical for ensuring the safe, efficient, and reliable transfer of renewable energy to the grid.

An integrated Supervisory Control and Data Acquisition (SCADA) system supports this expansive infrastructure, allowing site operators to maintain the plant 24/7, both locally and remotely. The system includes an advanced Grid Controller built on a high availability architecture to coordinate plant responses in alignment with the National Grid Corporation of the Philippines’ (NGCP) requirements.
