This page shows the list of structures, lands, and right-of-way (portion of a power line) that were acquired, designated, and built by National Transmission Corporation (TransCo), National Grid Corporation of the Philippines (NGCP), and various distribution companies and are part of a power line originally commissioned by National Power Corporation (NAPOCOR) and TransCo. Amount of structures built, and right-of-way and lands acquired and designated by TransCo, NGCP (as shown on High Voltage stickers/signs placed on steel poles and lattice towers) and various companies, and total number of lands and right-of-way designated and acquired and structures built (non-NAPOCOR/TransCo) are also shown in this page.
NOTE: If the line has two or more segments, on their Exceptions section, a power line segment is mentioned to determine which segment that those structures are belonged. Also if the replacement structure was built, and the lands and right-of-way were designated and acquired by NAPOCOR, they will not be included in this page.
