Sucat–Araneta–Balintawak Transmission Line

The Sucat–Araneta–Balintawak Transmission Line (abbreviated as SA on its Sucat–Araneta segment) is a 230,000 volt, single-circuit, three-part transmission line in Metro Manila, Philippines that passes through the cities of Muntinlupa, Taguig, Makati, Manila, and Quezon City. 

Route description 
The  Sucat–Araneta–Balintawak Transmission Line began construction in 1996 and went into service in 2000.  Originally commissioned by National Power Corporation (NAPOCOR), it is now operated by the National Grid Corporation of the Philippines (NGCP). 

The line consists of:
 212 steel poles (Balintawak–Araneta segment: 1-54; Araneta–Paco and Paco–Sucat segments: 1-8, 30-149, and 155-185)
 26 lattice towers (9-29 and 150-154)
 2 portal towers located between steel poles 49 and 50 ((8LI1MNA-MUN)97), and 53 and 54 ((8LI1MNA-MUN)92)

With the construction of the Skyway Stage 3, several steel poles are being replaced by newer ones specifically those along the Araneta segment. 

Sucat–Paco 
The transmission line starts at Sucat Substation of National Grid Corporation of the Philippines (NGCP) where it parallels Manuel L. Quezon Avenue and Laguna Lake Highway before it turns left.  It then passes to Diego Silang Village and parallels with Carlos P. Garcia Avenue.  It goes to the left again, passing through Manila American Cemetery and Bonifacio Heights before paralleling to South Luzon Expressway (SLEx).  At SLEX, it crosses to Epifanio delos Santos Avenue (EDSA) through the Magallanes Interchange.  It continues on a straight route and after crossing Gil Puyat Avenue are 7 new steel poles that were used for the relocation of poles due to the construction of Skyway Stage 3.  It crosses to San Andres Bukid and Paco.  The cut-in connection to Manila Electric Company (Meralco) Paco/Manila substation is located in this district. 

Paco–Araneta 

The line parallels to Tomas Claudio Street (or Paco–Santa Mesa Road), PNR Metro Commuter railroad and Magsaysay Boulevard, turns left to Gregorio Araneta Avenue, and the line's Sucat–Araneta section ends at Araneta Substation. 

Araneta–Balintawak 
The line continues paralleling Araneta Avenue until it passes to Valentin Ventura Street, Tuktukan Street, and Kaingin Road before it crosses to EDSA.  It turns left and after a few meters is the transmission line's terminus which is Balintawak Substation. 

Health controversy 
The Sucat–Araneta–Balintawak Transmission Line, specifically the segment between SLEx in Makati and Bonifacio Heights in Taguig, was criticized by the residents living along the Tamarind Road in Dasmariñas Village, Makati, who claimed the transmission line pose health risks.  The said segment is located within 10 meters of Tamarind Road in the said village.  The residents, led by Atty.  Eduardo F. Hernandez, blamed the electromagnetic fields (EMF) emanated by the 230-kV power lines for such health issues as cancer, leukemia, and miscarriage.  They also took note of no consultation with regards to the construction of the transmission line.  In response to the petition filed by the residents, the Supreme Court ruled in 2006 that the safety issue of the lines was "evidentiary in nature," although they took note of the potential health risks due to EMF radiation exposure with regards to the scientific studies.  The Court also added that long-term human safety should be of paramount importance as opposed to the presumption of economic benefits.
