Alijis Substation Power Transformer: When Old Age Takes Its Toll

The massive brownouts that Bacolod City experiencing right now are the result of the ailing equipment of CENECO. Sadly, the company never acquired new equipment that could have improved their electricity distribution services. Thus, the Alijis Substation’s 30/37MVA power transformer finally collapsed and suffered irreparable damage. Since Alijis is a large community, it requires a lot of electricity to power up businesses and residences. Hence, a rotation is the best option until the new transformer arrives. Read more.

The Story of the Alijis Substation Power Transformer

After 13 years of dedicated service, plus incidents of overloading in the past, the 30/37 MegaVolt Amperes (MVA) power transformer at the Alijis Substation in Bacolod City suffered a critical blow at about 9 PM last Wednesday. This resulted in a widespread power outage across all seven connected feeders.

Engr. Bailey Del Castillo, Negros Power’s Chief Operations Officer, reported that the transformer experienced a significant oil leak, rendering it irreparable in its current state.

In response, Negros Power has found it more viable to replace the damaged transformer with a new unit. However, due to the necessary installation processes, it is estimated to take approximately two weeks before the new transformer can be fully integrated into the system.

As an interim solution to reduce the effects on consumers, Negros Power engineers have rerouted and connected the feeder lines from Alijis Substation to nearby substations and feeders. This has allowed them to provide a temporary power supply of around 32 Megawatts to the affected areas.

Continuous Work

To prevent overloading, Negros Power will closely monitor the said feeders and may implement Manual Load Dropping as a precautionary measure to abort possible unscheduled power interruptions.

Negros Power appeals for understanding from all affected consumers during this period of reconfigurations to give better service shortly. The company assures consumers of ongoing efforts to restore normal operations and ensure a consistent power supply while addressing the challenges at Alijis Substation.

A 5-Year Plan

At this point, Negros Power has not yet fully taken over the operations of CENECO as they await their Certificate of Public Convenience and Necessity (CPCN) from the Energy Regulatory Commission (ERC).

Looking ahead, Engr. Del Castillo outlined plans for the comprehensive rehabilitation and modernization of the Alijis Substation and other inherited facilities from CENECO. This is all part of a 5-year program set to commence next month. Unfortunately, the Alijis substation gave way before the appointed time.

This initiative will be initiated following the granting of the CPCN, which will mark a significant step in Negros Power’s evolution as the new Distribution Utility in Bacolod City and Central Negros.
