The Visayas grid continues to suffer from a power supply crunch, prompting the National Grid Corp. of the Philippines (NGCP) to place the region under red alert for three hours on Friday.
In an advisory, the red alert would be up from 5 p.m. to 8 p.m.
Likewise, a yellow alert would take effect from 2 p.m. to 5 p.m., and 8 p.m. to 10 p.m.
A yellow alert indicates that available power reserves are thinning, meaning any unexpected plant outage could trigger service interruptions. A red alert means that supply cannot meet demand, which increases the likelihood of rotational brownouts unless we manage consumption effectively.
The available capacity remained thin at 2,307 megawatts (MW) as of 8 a.m., while peak demand was 2,402 MW
