The Philippines Terra Phase 1 West Project combines 1.4GWp of solar photovoltaic generation with 3.3GWh of battery energy storage, requiring a large-scale medium-voltage AC collection and power distribution system.
China Energy Engineering Group Guangdong Electric Power Design Institute Co., Ltd. (GEDI) serves as the EPC contractor for the project.
Anhui Tiankang Group was selected as the supplier for AC high-voltage cable Package 2, providing 35kV power cables with large conductor cross-sections together with a detailed cable ampacity test report. The contract value exceeded RMB 74.6 million (approximately USD 10.3 million), with deliveries scheduled from May to June 2025.
The project required an extensive 35kV AC collection system for collecting and distributing power generated by the solar PV facilities. The cable system needed to accommodate the project's high current requirements across a large-scale renewable energy installation.
The project required 35kV cables with conductor cross-sections of 400 mm², 500 mm², and 630 mm². These large cross-section cables require appropriate manufacturing capacity, process control, quality inspection, and handling during production and shipment.
The project required a comprehensive cable ampacity test report based on applicable IEC requirements, covering current-carrying capacity under specified air and soil installation conditions.
The assessment included different ambient and soil temperatures, soil thermal resistivity values, and burial depth to support cable selection and ampacity evaluation for the project.
The cable package required export shipment from China to the Philippines, with delivery coordinated in three batches to match the project's construction schedule.
The project required technical and quality documentation including datasheets, factory inspection and test reports, material certificates, and other EPC project documentation.
Anhui Tiankang Group supplied a comprehensive AC high-voltage cable package for the Terra solar + storage project.
