When asked on Facebook exactly when brownouts would be scheduled, Noreco replied that there is nothing "scheduled", only that they may have to shutdown power if there is not enough available for demand. They said, luckily, so far they have had enough for demand and haven't needed to shutdown. For your perusal:
I don't know much about the electrical grid in the Philippines, but you would think that after the recent large earthquake centered on Bohol and the recent typhoon that the associated damage and subsequent drop in the number of houses and business establishments would cause a drop in demand.
