The sole distribution utility in Iloilo City will invest a total of P3 billion to further improve the electricity supply grid of the city.
In an interview with Daily Guardian on Air via Aksyon Radyo-Iloilo on Friday, Engr. Bailey del Castillo, deputy head of network operations of MORE Electric and Power Corp., said their top management approved a total of P3-billion capital expenditure (capex).
The additional capex of P1.1 billion is on top of the P1.9 billion emergency capex, of which almost P1 billion has been spent since MORE Power took over the city’s distribution services in 2020.
The P1.9-billion budget was used on emergency works such as rehabilitation of substations, replacement of poles and distribution lines, and replacement of transformers and construction of the Banuyao switching station.
The second tranche amounting to P1.1 billion will be primarily allocated to the upgrading of substations which supply electricity from the grid to the city districts in the next three years.
MORE Power has started the construction of new Megaworld substation and uprated the power transformer of City proper substation.
Mandurriao and City Proper are now the fastest growth areas in the city while need to construct a new substation in Arevalo because it is at the tail-end of the grid.
“There will be addional three new substations which are brand new – the new Megaworld substation, the 36 MVA mobile substation from Europe, and the new Arevalo substation. Arevalo is at the far end of the grid, and we need to install a new substation to address the problems of low voltage, systems loss, among others,” del Castillo said.
The other five substations will also undergo rehabilitation and upgrading, which means the old facilities will be torn down and replaced by more modern equipment.
“When we say rehabilitate, we will do ground zero para pagkatapos, lahat bago. Currently, some of the structures are made of wood. The concrete and steel structures are really old. We will still use equipment that are still serviceable but overall, everything will be new,” del Castillo said.
The new mobile station will be deployed to take over the operations of the fixed substations when these are rehabilitated one at a time.
“The mobile substation will first be used when we work on Molo substation then Mandurriao, then LaPaz and Jaro where it will be permanently based,” he added.
To avoid prolonged and widespread outages, del Castillo said they transfer the loads of the substation to other feeders during the rehabilitation works.
“The interruptions will only occur during the switching but it will not take long. Once the rehab works start, electricity will continue to flow,” he added.
Del Castillo said they are confident that once the rehabilitation works are finished, the distribution system will become stable and reliable.
“The system will become very robust because it will become a loop already. While we upgrade the facilities, they will be connected to each other. By 2025, our system will be brand new and robust,” he said.
Under the loop distribution system, power supply will continue even if one substation conks out as the supply and feeder lines can be transferred to another in a fast and safe manner.
As to the distribution lines and poles, del Castillo said they still need to replace around 35 percent of the old primary facilities.
“We are now focusing on the lines in the interior parts of the city, especially the secondary lines. But I can see that the city’s future is very bright given that we are now normalizing and our demand is picking up,” he added.
