Route description
Lines 1 and 2

The transmission line consists of 172 steel poles, 51 lattice towers, and 1 H-frame with a total of 224 transmission structures.
Expansion and improvements
Line 3 of the transmission line, which have a length of Шаблон:Convert and also commissioned by NAPOCOR/NPC. The project started on March 13, 1995, completed on December 6, 1996, and energized on December 22, 1996.[4]
On August 28, 2009, National Grid Corporation of the Philippines (NGCP) began construction of line 4 of the transmission line. It was completed on June 27, 2010[5]
Due to the construction of Skyway Stage 2, NGCP constructed bipole 47A located near Skyway and SLEX.
