The NGCP has commenced work on the upgradation of the 230 kV San Jose-Quezon Line 3 project, as the Quezon City government has granted right-of-way (RoW) clearance for the seven transmission tower sites located in Barangays Baesa and Sangandaan. The upgradation work on the project involves the expansion of the San Jose and Quezon substations. The expansion of the project will widen the power corridor into Metro Manila, and allow supply from power plants to feed the Luzon load centre. It will also relieve the existing transmission line, prevent overloading, and ensure that the NGCP maintains the line’s N-1 contingency. N-1 refers to the ability of the transmission grid to withstand a major power disturbance through redundancies in the grid system.
