Meralco warns Malacanang power source 'likely to fail'

MANILA - Palace may see dark days in the near future as the Manila Electric Co. (Meralco) said a 52-year-old power transformer bank servicing it and the Philippine General Hospital (PGH), among others, is likely to fail.

“Notwithstanding the remedial measures conducted to prolong the life of the said transformer, succeeding tests on [Tegen 83 Megavolt ampere [MVA] bank No. 8] showed a continuing deteriorating condition,” Meralco said in its petition to the Energy Regulatory Commission [ERC].

The “deteriorating condition” of Tegen 83 MVA, one of four major power transformer banks of the Tegen Substation at Isla del Providor, Paco, Manila, “might jeopardize the safe, reliable, secure and efficient operation of Meralco’s distribution system, particularly the area and vital customers served by the Tegen Substation,” the company added.

According to Meralco, the Tegen 115-kiloVolt (kV) to 34.5 kV Substation provides electricity to the following: Office of the President, New Executive Building, and the Presidential Security Group in the Malacañang Palace compound; the Pedro Gil and Pureza LRT Lines 1 and 2 stations; Manila City government; and, the Supreme Court of the Philippines.

Aside from these public offices, Meralco said the Tegen Substation also provides power to the Manila Hotel, Adamson University; and, the Mapua Institute of Technology.

Meralco said tests the company conducted showed the Tegen bank No. 8 “with deteriorated busing insulation.”

“The continued deterioration and the advanced age of the power transformer indicate the likely failure of Tegen bank No. 8, which required immediate intervention.”

Meralco said it discontinued the use of the power transformer on August 20 “in order to avert any possible explosion or sudden and uncontrolled outage of Tegen bank No. 8.”

The company said using the other three banks with the discontinuation of bank No. 8 is risky as “any outage of the power transformer banks will result in a massive and prolonged power interruption in the area affecting the critical customers.”

Meralco also warned “the capacity deficiency at Tegen Substation” would make it difficult for the firm to accommodate “large customer applications, such as Sun Trust Pakview and Midtown Peninsula.”

Hence, the company said it is seeking the approval of the ERC to undertake an emergency capital expenditure of P75.81 million (roughly $1.74 million) for the emergency installation of a new power transformer for the Tegen substation.
