Route Description
The 34-kilometer (21 mi) Sucat–Paco–Araneta–Balintawak Transmission Line began construction in 1996[1] and went into service in 2000. Originally commissioned by the government-owned National Power Corporation (NAPOCOR), it is now operated and maintained by privately-owned National Grid Corporation of the Philippines (NGCP). It passes through the cities of Muntinlupa, Taguig, Makati, Manila, and Quezon City.
