After one of the 150-megawatt units of Davao Light and Power Co. or DLPC 's coal-fired power plant returned online on Monday which experienced an emergency shutdown on April 6 due to a boiler tube leak, the Aboitiz-owned company said that the power situation within it's franchise had improved. With this, the duration of of the rotating brownouts in Mindanao would be decreased to two to three hours or at most, decreased to two hours, during the peak period (8:00AM to 8:00PM) and one hour during (7:00AM to 8:00AM and 8:00PM to midnight) which is the off-peak period. The DLPC will be expecting an additional supply of 50 megawatts on May 1 to alleviate the situation.
