Visayas Grid Struggles, Faces Yellow Alert as Power Demand Rises

The single sharpest fact in one or two punchy sentences. Who did what, where, when, and why it matters. Not a summary of everything — the one thing that makes someone stop scrolling.

The Visayas grid faced another day of struggle as the National Grid Corporation of the Philippines (NGCP) issued a yellow alert due to persistent outages and rising power demand. The alert was issued on Monday, July 12, from 5 p.m. to 8 p.m. as the grid had 2,602 megawatts (MW) of available capacity against a projected peak demand of 2,376 MW. This marks the second time in a week the Visayas grid has slipped into a yellow alert, the third this month alone.

NGCP spokesperson Cynthia Alabanza explained that the power outages were caused by a combination of factors, including transmission losses, distribution problems, and forced outages at several power plants. So far this month, eight power plants have been forced to shut down due to various issues, with four plants offline since June, seven since May, one since March, and three since the start of the year. The plants that have been offline for the longest have been those operating on natural gas, with several experiencing malfunctions.

According to NGCP data, the plants that have been forced to shut down have a total capacity of 1,500 MW, which is roughly 45% of the total power generation in the Visayas region. NGCP has implemented measures to mitigate the effects of the power outages but admits that the situation remains tenuous.

In response to the yellow alert, NGCP has urged consumers to reduce their power usage during the peak hours to prevent a widespread blackout. Residents in Cebu and other areas were reminded to turn off non-essential appliances and lights to help alleviate the pressure on the power grid.

A recent report by the Department of Energy (DOE) highlighted the need for a more sustainable energy mix to support the country's growing demand for power. The agency noted that renewable energy sources such as solar and wind power were vital in addressing the issue of power supply and reducing the country's reliance on fossil fuels.

The DOE has committed to increasing the share of renewable energy in the country's energy mix to 30% by 2030, which includes solar, wind, and hydroelectric power. However, experts have raised concerns that this target could be challenging to achieve given the current state of the country's infrastructure and the rising costs of renewable energy technologies.

The Visayas region, which accounts for a significant portion of the country's power demand, has been experiencing frequent power outages in recent months due to various factors, including transmission losses, distribution problems, and forced outages at several power plants. NGCP and the DOE have called on consumers to be vigilant in their energy usage to help alleviate the pressure on the power grid.

The situation highlights the need for a more sustainable energy mix in the country and the importance of investing in renewable energy technologies. The DOE's commitment to increasing the share of renewable energy in the country's energy mix is a step in the right direction, but experts caution that the challenge will be to ensure a steady and reliable supply of power to households and businesses.

Meanwhile, NGCP has assured consumers that measures are in place to mitigate the effects of the power outages, including the dispatch of emergency teams to affected areas. Residents are advised to monitor the news and social media for updates on the power situation in their areas.

NGCP's yellow alert highlights the vulnerability of the country's power grid as demand continues to rise. The agency's measures to prevent a widespread blackout will be closely monitored.
