DOE: No fuel supply constraints despite red, yellow alerts

DOE-Transmission lines

Despite the yellow and red alerts raised over the Luzon Grid on Monday, Department of Energy (DOE) Secretary Raphael Lotilla said that there is no fuel supply constraints in the grid. 

“We assure the public that the DoE is verifying the cause of the forced outages this morning as there appear to be no fuel supply constraints. A team from the DOE will conduct actual physical spot checks and validate the condition of the transmission lines and the affected power plants,” Lotilla said in a statement. 

Earlier today, the National Grid Corporation of the Philippines (NGCP) placed the Luzon Grid on red alert from 1:00 to 4:00 PM and on yellow alert from 9:00 AM to 1:00 PM and 4:00 PM to 9:00 PM as seven power plants went on forced outage, while three others are running on derated capacities. 

3,627 megawatts (MW) were shaved off from the grid following the alerts. Data from NGCP said states that Luzon Grid’s available capacity is at 10,727 MW while peak demand is at 10,585 MW. 

A yellow alert is declared over a grid whenever power reserves fall below ideal levels. If the supply-demand balance worsens and points to severe power deficiency, a red alert is declared which may lead to rotating power interruptions.
