The cause of the outage was an overcurrent ground as a result of high voltage conductors making contact in the high winds on Chalan Monsignor Guerrero Road fronting the Kiya Substation tripping the Kiya 3 Circuit.
This vault inevitably triggered a low frequency and disconnected the Aggreko Power Plant tripping Feeder 4 and 7, which includes Lower Base, Sadog Tasi, Capital Hill, As Quina (Wireless), Mt. Tapochao, Talafofo, I-Denni, Agag, As Teo, Papago, entire Kagman, Lower Base, Tanapag, As Mahetog, Achugao, San Roque, As Matuis, Marpi, As Lita, Chalan Monsignor Martinez Road, Tottotville, Koblerville, Afetnas, San Antonio, Fina Sisu and Chalan Piao, Gualo Rai, Chinatown, Garapan and Chalan Kiya.
Power to the affected areas were fully restored at around 10:30 a.m. after CUC operators were able to re-energize the engines.
Water and wastewater services were not affected during this outage period.
CUC operators are currently monitoring the power plant’s engines and are currently working with the power division on scheduling an emergency power outage for the proper installation of the inefficient installed distribution lines that caused the power outage Thursday. Updates will follow as soon as they are available.
