Regarding the shutdown of one of Therma South's 150-mw units, Aboitiz Power Corporation executive Wilfredo Rodolfo III explained that it was meant to undergo a 10-day emergency shutdown which took effect noon of Tuesday with the second 150-mw unit remained operational. He added that the shutdown was implemented to address problems in the power plant preventing it to recur in the future quoting, " The emergency shutdown was made to address the potential problem seen in the boiler before it affects the overall operation of the power plant. If we do not address this problem now, it may occur and cause us bigger problems in the future. So it is prudent and better to address the situation promptly. "
