Route description

The Concepcion–Clark Transmission Line went into service on August 24, 2008. Originally commissioned by the government-owned National Transmission Corporation (TransCo), it is now operated and maintained by the privately owned National Grid Corporation of the Philippines (NGCP). Line 1 was energized at 69kV on July 11, 2008 and line 2 on August 24, 2008 and were later uprated to their current voltage of 230kV on December 9 and November 30, 2009, respectively.[1] It passes through the municipalities of Concepcion and Bamban in Tarlac and the city of Mabalacat in Pampanga. It is located within the service area of NGCP's North Luzon Operations and Maintenance (NLOM) District 6 (South Central Plain). From Concepcion Substation until its entry to SCTEx, upon passing through New Clark City exit and Sacobia River, and at its terminus at Clark Substation, the line uses lattice towers. Steel poles, however, are used from its entry to SCTEx until its approach to New Clark City exit and after Sacobia River to Clark North Exit.

The transmission line starts at Concepcion Substation, parallels with San Manuel–Concepcion–Mexico transmission line, turns right upon entering Subic–Clark–Tarlac Expressway (SCTEx) and run parallel into the said expressway until Clark North Exit. It then intersects with San Manuel–Concepcion–Mexico line before passing through Concepcion Exit. Between Concepcion and New Clark City exits, line 2 of the transmission line passes through Seaoil gas station and CityMall SCTEx while line 1 passes through PTT gas station. Upon approaching New Clark City exit and passing through Sacobia River, the line will utilize the western side of SCTEx. It again utilize both sides of the expressway after passing the said river, continues straightforward, and ends at Clark Substation.

Components

The transmission line consists of 185 steel poles, 20 lattice towers, and 2 portal towers totaling to 207 structures.

  • A portion of the transmission line near Concepcion Exit.
  • Portion of the transmission line's line 2 passing through Seaoil gas station and CityMall SCTEx in Concepcion, Tarlac.
