Project: Transmission lines for the Opol Substation
Client: National Grid Corporation of the Philippines (NGCP)

The National Grid Corporation of the Philippines (NGCP) has contracted Meralco Industrial Engineering Services Corporation (MIESCOR) to undertake construction services for its new substation on a four-hectare site along the national highway in Barangay Awang, Opol, Misamis Oriental some 15.5 kilometers west of its Carmen substation.
MIESCOR’s contract involves the erection of new double circuit, single strung steel towers along a 7.5 km. stretch of the new 138 kV transmission line and replacement of 54 kms. of Overhead Ground Wire (OHGW) with Optical Ground Wire (OPGW) under live- line conditions. NGCP stated that the planned Opol substation would reinforce the 60-kilometer Lugait-Carmen 69-kV line constructed in 1966 which has already been experiencing a 90 percent peak load of its rated capacity. The grid operator estimates peak load could reach 103 percent this year hence the urgent need to replace it with the Opol 138-kv line.
