MANILA -- The Visayas grid is on Yellow Alert on September 16, Wednesday.
In a Facebook post, the National Grid Corporation of the Philippines (NGCP) said the grid will be on Yellow Alert until 8 p.m.
Earlier on Wednesday, the NGCP said the grid would be on red alert from 5 p.m. to 6 p.m., and on Yellow Alert from 4 p.m. to 5 p.m. and from 6 p.m. to 8 p.m.
The agency lifted the red alert status for the grid at 1:10 p.m.
The NGCP said available grid capacity is now at 2,584 MW. Peak demand is expected to reach 2,394 MW.
A red alert status means power outages can be expected as power supply is insufficient to meet consumer demand and the transmission grid’s regulatory requirements. A yellow alert, meanwhile, means power outages are likely as plants are producing less than the grid's contingency requirement.
The Visayas grid has been on Red and Yellow Alerts for months.
The Energy Regulatory Commission has ordered the retroactive implementation of the secondary price cap in the Visayas and Mindanao spot market for August electricity trading and thereafter.
This came after the Independent Electricity Market Operator of the Philippines (IEMOP) announced that spot market prices in the Visayas and Mindanao jumped to record levels due to the shutdown of many power plants in the regions.
