Transmission firm National Grid Corporation of the Philippines (NGCP) is seeking immediate regulatory approval for its P1.6-billion Cebu facility upgrade to underpin the wheeling of electricity output of a key power project in the Visayas grid.
The company noted that its proposed transmission line connection and substation in Cebu will be an “integral component of the recommended scheme for the connection of the TVI (Therma Visayas, Inc.) power plant to the grid.”
The power plant is of 340-megawatt capacity and is targeted for commercial commissioning by 2017. It is being developed by the Aboitiz group.
For the propounded transmission facility support to the project, NGCP has proposed that a new 230-kilovolt substation will be constructed to “facilitate the energization of the Cebu-Lapu-Lapu transmission line at 138kV and its proposed connection to the existing Colon-Cebu 138kV line 1.”
As laid down, a temporary connection shall be established for the transmission facilities but the project shall have provision for the setting up of more permanent structures in the future.
“The temporary connection scheme will involve the installation of 138-kV underground cable which will be routed along the proposed cable trench for the Cebu-Lapu-lapu 230kV transmission line,” NGCP has emphasized.
The duration of the project’s implementation, it said, will be for 28 months – including the topographic and geological survey, preparation of bidding documents, procurement stage and actual construction.’
The Energy Regulatory Commission (ERC) has scheduled public hearing on this transmission project application for June 2 this year.
NGCP stressed that “without the project, the 230kV transmission lines from the proposed switching station in Bato towards Cebu substation will be inoperable and TVI will not be able to dispatch its capacity to the grid.” It added that “the connection of the TVI power plant to the transmission system will vastly improve the adequacy and reliability of the power system in Visayas.”
NGCP further stressed that given “the necessity of the project and the length of time necessary for its completion, its implementation must commence as scheduled.”
