The ERC also approved Megasol Energy 1 Inc.’s 41.244 MW Gamu Solar Power Plant in Isabela. The project will connect to the Luzon grid through the 69 kV Gamu-Roxas line.
What is the largest solar installation in the Philippines?At the time, 778 MW of solar had been installed, making it already the largest solar installation in the Philippines. The first phase, which also includes a 500 kV transmission line to the Nagsaag-San Jose connection, is due for completion in 2026.
How will Bess & NGCP connect to Luzon power grid?A transmission line will connect the plant and BESS to the Luzon power grid managed by the National Grid Corporation of the Philippines (NGCP). The hybrid project will feature a 500kV 13km long transmission line with 89 towers. The infrastructure will use 4-410mm 2 Thermal Resistant Aluminium Alloy Conductors Steel Reinforced (TACSR) per phase.
