NGCP Visayas Power Restoration Advisory as of 7PM, 12 July 2017

Date Published: 7/12/2017

Since July 6, or as soon as the earthquake hit, NGCP has been working 24/7, even in adverse weather conditions, to restore all affected transmission facilities while constantly updating the public on its actual restoration status.

NGCP is currently employing a parallel, simultaneous strategy of REPAIR, REPLACEMENT, and RECONFIGURATION for its affected transmission equipment.

For REPAIR, affected transformers will be re-tested and corrected for any damage. For REPLACEMENT, transformers from Cebu are being hauled and transported to Ormoc to replace unserviceable equipment. For RECONFIGURATION, 230kV lines from Compostela, Cebu will be reconfigured and stepped down to 138kV lines in order for power to reach Ormoc and be readily received by Distribution Utilities (DUs).

NGCP is also coordinating with concerned agencies on the deployment of power barges to supply the power requirements of Samar, Leyte, Bohol, and Biliran. Alternative options such as generator sets, long term solutions including mobile transformers, are also being carefully studied.

Last July 10, NGCP initially energized EDCís Marshalling Substation to provide feedback power to EDCís Upper Mahiao and Malitbog geothermal power plants but de-energized again at EDCís request due to technical difficulties by a still undetermined cause. NGCPís line is ready and awaiting clearance from EDC.

The 2-3 days timeline earlier given by NGCP was for the construction of the bypass line. Given the intensity of the earthquake, it is necessary to inspect even the most minute detail of every equipment, and if deemed damaged, implement corresponding repairs.

After countless tests, some of which were halted by inclement weather and strong aftershocks, NGCP was able to accurately confirm the extent of damage to its transmission facilities. This information was not available until late Monday (July 10) and was immediately released for the public's information as soon as the data was confirmed, as well as alternative options to expedite power restoration.

NGCP assures its customers and the public that it is pooling all its resources and exerting all efforts to restore, even partially, power transmission services by the July 31 deadline, as set by DOE, or earlier.
