"This led to the stopping of fuel (deliveries) two days ago from Egypt."
The electricity distribution company confirmed only one generator was operating, producing 23 megawatts of power -- which added to other sources means Gaza currently has a total of 93 megawatts a day.
More than 500 megawatts are required to serve the Palestinian enclave's population.
Internationally recognised Palestinian president Mahmud Abbas, who runs the West Bank-based Palestinian Authority, has recently sought to squeeze his longtime rivals Hamas, who control Gaza.
His government recently stopped paying for energy to Gaza, leading Israel to start reducing it.
The cut left the impoverished territory of more than two million people with as little as two hours of mains electricity a day.
As an interim measure Egypt stepped in to deliver fuel to Gaza's sole power plant, but that has now been threatened.
The Egyptian deliveries came as part of improving relations between Cairo and Hamas.
There was no immediate response from the Palestinian Authority.
