JIC Recovery Release No. 34 - GPA Update; GRTA Shuttle Service

GPA Update:

The Guam Power Authority (GPA) continues its restoration and post-typhoon recovery efforts. GPA reports that as of 1:00 p.m.:

  • 53.2% of the System Load (Customer Demand) has been restored.

  • 95.8% of GPA’s Substation Energization has been restored.

  • 88.9% of GPA’s feeders/circuits have been energized/restored.


Two additional feeders/circuits were added to the island-wide system for a total of 56 feeders/circuits that are partially energized today.


GPA advises that during restoration and recovery, the Island-Wide Power System (IWPS) may be unstable, with fluctuating voltages, power interruptions and intermittencies occurring. Once your power has been restored to your home or businesses, you may experience outages or interruptions. This is not unusual as the grid is fragile and a period of system instability will occur until full restoration is completed. Once your feeder/circuit has been energized, your power will return, even as interruptions or outages happen.


GPA will make every effort to have power restored as quickly as possible to our customers. Once full restoration is completed around the island, the system will stabilize and less power interruptions will occur. Additionally, if you detect voltage fluctuations such as extremely bright lighting or very dim lighting coming from lamps or lights, immediately unplug your "sensitive" appliances which include: refrigerators, air conditioners, computer and computer-related equipment, microwave ovens, etc.


Customers can contact GPA’s 24-Hour Trouble Dispatch at 475-1472/3/4 or via direct message on GPA’s Facebook page at www.facebook.com/GuamPowerAuthority.
