Power networks/Philippines/Mapped transmission and subtransmission lines constructed by each companies

This page shows the power lines that were originally constructed or commissioned by National Power Corporation (NAPOCOR), National Transmission Corporation (TransCo), National Grid Corporation of the Philippines (NGCP), and various power distribution companies. Majority of these are mapped in OSM, while others remain unmapped.

For the list of structures that were commissioned, and lands and right-of-way that were acquired and designated by TransCo and NGCP but are part of a power line originally commissioned by NAPOCOR and TransCo, see its Exceptions page.
