The next round of maintenance activities for the upgrade of the Ninoy Aquino International Airport (NAIA) Terminal 3 electrical systems will not occur during peak hours to ensure continuous operations.
In a statement, the Manila International Airport Authority (MIAA) said that upgrade works will start Wednesday, June 19 to June 21 with no or minimal effect on passenger and flight operations.
The activities were scheduled to occur after the last flight, away from peak hours of operations.
These maintenance activities include several functionality tests and safety integrations into the existing system, as well as termination procedures across eight different electrical substations in NAIA Terminal 3.
MIAA General Manager Eric Jose Ines assured that gensets will supply temporary power to areas under maintenance work.
"All critical systems for continuous processing of passengers and flights will remain unhampered by the ongoing works," Ines said.
The NAIA Terminal 3 has been the subject of scheduled power shutdowns to make way for a series of electrical maintenance tasks that have been ongoing since November 2023.
Travelers are expected to experience minor inconveniences like limited air conditioning, as well as non-operational escalators and elevators in certain parts of the terminal from time to time.
MIAA’s maintenance work involves replacing outdated components in the medium voltage switchgear at eight electrical substations within Terminal 3.
To recall, the first of the series of interruptions occurred from November 29 to December 13, 2023, covering different areas of NAIA Terminal 3.
“We apologize to all our airport stakeholders. Rest assured that the benefits of this electric systems upgrade will far outweigh the inconveniences it may bring in the course of its implementation. We seek for more patience and understanding from everyone,” Ines earlier said.
