DAVAO CITY- With major power plants down, Davao Light and Power Company is implementing 4-hour rotating brownouts which started yesterday (Nov. 23)
Art Millan, executive vice-president and chief operations officer of the DLPC said the main culprit is the preventive maintenance shutdown (PMS) of the STEAG power plant in Misamis Oriental, the Therma South Inc. coal-fired plant in Davao City and the Therma Marine Inc. power barge.
The Sibulan hydropower plant as well has advised reduced capacity to facilitate an emergency repair on one of its plant.
As of today (Nov. 23) the National Grid Corporation of the Philippines (NGCP) has allocated only 167 megawatts to DLPC over 100 megawatts lower than its power supply contract of 273 megawatts.
Millan hopes that the 4-hour rotating brownouts will last only for Nov. 23 as they expect the STEAG plant to go online at 12 midnight (Nov. 24).
He said the rotating brownouts would be around 2-3 days until the return of the other plants.
DLPC will continue to run the Bajada Power Plant and activate the Interruptible Load Program to compensate for the loss. This will have DLPC with 246 megawatt of power to supply the forecasted demand of 340 megawatt.
There would be power interruptions of about 3 to four hours during peak which is from 8 a.m. to 10 p.m. and a maximum of 1.5 hours during off peak (10 p.m. to 8 a.m.)
The ILP is participated by large corporate customers with big generator sets that would run during peak hours to give power to the grid. The ILP under the DLPC is around 30 megawatts.
The DLPC service area covers the entire Davao City, the city of Panabo and the towns of Carmen, Braulio Dujali and Santo Tomas in Davao del Norte.
Meanwhile Millan said another 50 megawatt of contracted power will be added to DLPC with the commissioning of the second unit of the TSI coal-fired power plant which was damaged last February.
The 150-megawatt unit is expected to start by December of this year with commercial operations to commence by February next year.
