The Energy Regulatory Commission (ERC) has approved Manila Electric Co.’s (Meralco) petition to proceed with the expansion of its substation in Bonifacio Global City (BGC) in Taguig to address a projected capacity deficiency in 2015.
In a ruling, the ERC declared that Meralco’s application to expand its substation is “sufficient in form and in substance.”
The expansion of Meralco’s FBGC-4 Substation, which would cost P253.52 million, will serve the power needs of large load customers and real estate developments in Taguig’s financial district.
It explained that the expansion will address the expected overloading of FBGC-4 Substation’s 83-megavolt ampere (MVA) Transformer Bank No. 1 (101 percent) in 2015 due to high load growth and new large applications in the said area.
It referred to applications from developers such as Federal Land, Megaworld, Shangri-La, and The Net Group, namely: Grand Hyatt Residences, Uptown Place Tower 1, 2 and Mall, and Net Park with a total expected demand of 25 MVA.
Without the expansion, Meralco said it would be difficult to accommodate new customers.
“This project will improve the system reliability and will provide better flexibility in the said area during contingencies,” Meralco said in its petition.
The FBGC-4 Substation currently houses a single 83 MVA, 115 kilovolt (kV)-34.5 kV, and power transformer bank.
Without a second 83 MVA power transformer bank, Meralco said the FBGC-4 substation would not be able to provide adequate capacity to serve the power requirements of BGC in 2015.
“This condition may lead to premature failure of the said power transformer bank. This would result in prolonged power interruption in BGC,” said Meralco.
The project involves the installation of a new 83-MVA, three-phase power transformer with on-load tap changer and an assembly of a three-phase, 34.5-kV indoor-type Gas Insulated Switchgear with seven vacuum power circuit breakers.
It includes as well one 1.2 ohms, 36 kV, 630 amperes neutral reactor, one 34.5 kV, 14.4 MVA (reactive) capacitor bank, and construction of four 34.5 kV underground feeders.
Currently, the residential and commercial customers in BGC are being served by 34.5-kV distribution feeders from the FBGC-4 Substation.
