A fire at an electricity plant on Thursday, September 22 affected the service of 3.5 million Puerto Ricans, leaving them literally in the dark.

The cause of the fire has yet to be determined, though no injuries were reported.

CNN reported that the government doesn't believe that the outage was the result of any kind of sabotage to the electric power company, however, the fire will be investigated. 

Classes at public schools and universities have been canceled, and The Associated Press reported that hospitals canceled all elective surgeries and non-urgent appointments. Many government employees were given the morning off.

"We hope that by Friday everything will have returned to normal," Javier Quintana, executive director of the Electric Power Authority, told reporters yesterday.

But governor Alejandro Garcia Padilla isn't too sure of that. He said in a press conference that the process of restoring power would be slow.

The Associated Press reported that power has been restored to more than 130,000 customers — out of a total of 1.5 million by early Thursday morning. 

"The system is not designed to withstand a failure of this magnitude," Garcia Padilla said to reporters.

The blackout also caused 15 fires throughout Puerto Rico, which resulted in malfunctioning generators. All have been extinguished.

This unfortunate event is just the latest to plague Puerto Ricans whom continue to be in turmoil because of the territory's economic crisis.

Back in February, The New York Times reported that electricity is one of the biggest causes of Puerto Rico's $72 billion dollar debt.

"The power authority has been giving free power to all 78 of Puerto Rico’s municipalities, to many of its government-owned enterprises, even to some for-profit businesses — although not to its citizens," The New York Times reported. "It has done so for decades, even as it has sunk deeper and deeper in debt, borrowing billions just to stay afloat."

Despite this setback, Puerto Ricans are remaining positive. Some expressed their feelings about being left out in the dark took on social media.

Even tourists weren't upset.

Lin-Manuel Miranda even chimed in with this hilarious tweet:

Governor Garcia Padilla said in a press conference that "no amount of money or maintenance" could have prevented the fire at the power plant.

He said the switch, where the fire began, had received proper maintenance.

"Given that the system is so old, numerous setbacks could occur," Garcia Padilla said.
