(Fadian, Mangilao) – As of 5:00 p.m. today, the following is Guam Power Authority’s current status of the Island-Wide Power System (IWPS) and other power related updates:
 
  • Guam's IWPS did not experience a system blackout, however main transmission lines powering the southern part of the island went down, with no power currently servicing the south.
  • GPA has about 20% of distribution feeders online and most transmission lines powering the northern part of Guam is intact.
  • GPA’s Dededo Combustion Turbine (CT) 1 & 2 units continue to supply power to northern loads including Andersen Air Force Base and Camp Blaz Marine Base, Guam Memorial Hospital (GMH) and Tumon row underground systems.
  • Manengon diesel unit#1 and Ukudu gas turbine (GT) unit #3 remain operational throughout the storm, delivering power to the remaining load and feeders online.
  • All other GPA power plant units were secured as loads decreased throughout the duration of the storm.
  • GPA does not anticipate any generation capacity shortage, and plans to restore power service using the remaining base load and reserve units.
GPA is aware of multiple outages caused by strong winds and gusts including down transmission lines affecting most customers. Crews are prepared to immediately begin key assessments and restoration efforts as soon as winds decrease to safe levels. This will begin the recovery phase of the Island-Wide Power System (IWPS) around Guam. GPA crews continue to work 12-16 hours per day once restoration begins.

Initial priorities of our GPA crews include working on transmission lines to energize all substations, and address all water well issues.

GPA asks the public to please stay away from all downed or low-hanging power lines and equipment, assume it is energized and can cause harm if you come in contact with the lines or equipment. Consider such situations as dangerous and life threatening. If such conditions are present, please immediately report this to GPA’s 24-hour Trouble Dispatch at 671 475-1472/3/4 or via direct message on GPA’s Facebook page.

GPA asks for the community's patience and understanding as we get through this storm together.

Customers are encouraged to follow Guam Power Authority, Guam Homeland Security/Office of Civil Defense, and National Weather Service (NWS) Guam for the latest updates.
