Davao Light upgrades vital substation to meet growing energy demand

In the major business district area of Davao City, stands a large steel structure humming almost inaudibly beside the noisy and busy J.P. Laurel Avenue. Known as ERA Substation, this vital structure of Davao Light and Power Co., Inc. (Davao Light) powers parts of the city’s residential, commercial, and industrial areas. Today, it has an upgraded capacity of 300 megavolt-amperes (MVA) ensuring power reliability and securing enough load to cater to the city’s ever-growing population.

 

Considered the backbone of the power distribution network, substations and lines are vital facilities that ensure the delivery of power to every home, business, and industry. In particular, ERA Substation transforms electricity from 138 kV/69 kV or sub-transmission level voltage to supply the 69 kV/13.8 kV substations. These substations then further step down the voltage for distribution transformers energizing end-users such as homes and businesses.
