The National Grid Corporation of the Philippines (NGCP) will implement on Monday a nine-hour power curtailment in five provinces in Mindanao.
In a letter sent to electric cooperatives and power firms in Mindanao, Maximo Adiong of the NGCP Mindanao System Operations said the load curtailment is due to a scheduled shutdown of the Maramag-Kibawe 138-kilovolt transmission line.
The shutdown, Adiong added, will facilitate the stringing and tapping works, and eventually commissioning, of the new Maramag-Bunawan 230-KV transmission line.
Since transmission loading is limited to only 450 megawatts, the NGCP Mindanao has requested the power firms and cooperatives to implement voluntary load curtailment.
“This will prevent overloading of power transmission highways,” Adiong said in his letter.
The power curtailment will affect the Cotabato Electric Cooperative (Cotelco), South Cotabato Electric Cooperative (Socoteco) 1 and 2, Davao del Sur Electric Cooperative, Sultan Kudarat Electric Cooperative, Maguindanao Electric Cooperative, and the Cotabato Light and Power Company Inc., in Cotabato City.
Since Cotelco may use a loading limit of 16 megawatts on Monday, which is only 40 percent of its daily load, it will implement curtailment in its sub-stations from 9am to 5pm., according to its spokesperson Felix Canja
Cotelco has seven sub-stations in its area of coverage. Each sub-station will experience a one-hour power blackout starting 9am.
Canja has advised power consumers to be extra cautious in using alternative sources of light during blackouts as these may cause fires if left unattended. (Malu Cadelina Manar/MindaNews)
