The Energy Regulatory Commission
approved the application of National Grid Corp. of the Philippines to construct
new transmission towers that can withstand strong typhoons in northern Panay.
NGCP, which operates the country’s
power grids, filed an application with ERC to upgrade the Panitan-Nabas
138-kilovolt transmission line, which would involve the construction of new
structures.
ERC said that based on the perusal
of evidence filed by NGCP, the upgrading of the Panitan-Nabas 138 kV line would
cost P933.77 million. The project was expected to redound to the benefit
of consumers in terms of continuous, efficient and reliable power supply.
The project is also expected to
improve the reliability of the Panitan-Nabas 138 kV transmission line which
suffered catastrophic damage from the onslaught of super typhoon Yolanda in
November 2013, it said.
“It is clear that the wind
velocities carried by super typhoon Yolanda were greater than the design wind
velocity used in the transmission lines, thus constituting the main cause of
the tower toppling,” NGCP said in its application.
The project would involve the
construction of 123 new steel towers and structures, in conformity with the
required design standards for 138-kV lines. The structures will provide
more reliable clearances between overhead lines and nearby vegetation.
New transmission towers are to be
constructed in place of toppled structures. The new towers are to be built at
new sites to enable the construction of new foundations.
“However, additional rights-of-way
may be required, as other towers shall be located at new sites to be able
to construct new foundations,” NGCP said.
NGCP cited the need to immediately
complete the upgrading of the Panitan-Nabas 138-kV line to minimize exposure to
fault along the temporary by-pass lines and avoid load curtailment at the
Panitan substation.
