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.
