As of next month Guam's power bills will be about 9 to 11 percent higher.
The Pacific Daily News reports the Guam Power Authority has convinced the Public Utilities Commission that the agency needs extra cash to pay for spiking fuel costs.
Power officials told commissioners that the rate increase was not optional.
All of the island's electricity is generated by either gasoline or diesel.
The Commission meeting was scheduled after GPA officials filed an emergency petition requesting the commission to stabilise fluctuating fuel rates for at least the six months.
