In a bid to counter the expected upcoming load growth in General Santos city, the National Grid Corporation of the Philippines (NGCP) is reinforcing its existing high voltage transmission line from Matanao town in Davao Del Sur to the southern city of General Santos in South Cotabato. The transmission system operator began constructing the 70 km Matanao–General Santos line (138 kV) in October 2012. Further, the project also involves the expansion of the Matanao and General Santos substations and includes the installation of power circuit breakers and the corresponding accessories that protect the substation equipment from damage in case of overloading. The transmission line is expected to be completed in the first quarter of 2014, while the substation expansion is scheduled to be finished by November 2014.
