The majority of power customers in Puerto Rico who were left in the dark
earlier this week following a massive blackout that affected over a
million residents had their electricity restored on Saturday.

The two entities in charge of providing electric services to 1.5 million
power customers in Puerto Rico said their crews have been working hard
since Wednesday night when a circuit-breaker at the Costa Sur generation
plant, one of four main plants on the island, caught fire and caused the
remaining power plants to shut down.

Power has been restored to at least 1.3 million customers as of late
Saturday morning, according to Luma Energy, the Canadian-American private
company that took over Puerto Rico�s power transmission and distribution
last year.

As roughly 87 percent of customers gained access to electricity, Luma
Energy also urged consumers to limit their power use in order to avoid
energy demand upticks that could hinder the ongoing restoration process at
some of the main power plants.

Workers from the Puerto Rico Electric Power Authority, the bankrupt public
corporation in charge of controlling power generation units, have
reconnected at least seven of the shutdown plants.

On Saturday morning, the power authority said on Twitter that it started
working on reconnecting Puerto Rico�s two largest power plants, Costa Sur
and EcoEl�ctrica.

"As long as the EcoEl�ctrica and Costa Sur units are not in service, the
system will not have the required energy reserve," to deal with setbacks,
the power authority said in Spanish.

Costa Sur, the largest power plant in Puerto Rico, represents 57 percent
of the island�s natural gas-fired electricity generating capacity. A
series of strong earthquakes that struck southern Puerto Rico in 2020
significantly damaged both Costa Sur and EcoEl�ctrica.

The massive outage has enraged Puerto Ricans who already pay almost twice
as much as customers in the U.S. mainland for unreliable electricity.

On Friday evening, about a hundred outraged protesters marched in front of
Luma Energy�s headquarters. Some even threw eggs at the building and
dropped off bags of spoiled groceries that went bad after people were
unable to refrigerate them because of the outage.

As the roar of generators and smell of diesel filled Puerto Rico's air for
more than two consecutive days, the local fire department said they
responded to at least 17 fires caused by generators. Two people were
injured as a result of the fires, NBC�s sister station Telemundo Puerto
Rico reported.

Puerto Rico�s electricity system was decimated by Hurricane Maria in 2017,
triggering the world�s second-longest blackout. Emergency repairs were
made at the time, but the reconstruction and essential work to modernize
the island�s antiquated electric grid has not yet begun. Power company
officials blame aging, ill-maintained infrastructure for the ongoing
outages.

The federal government has already committed $12 billion in aid toward
revamping Puerto Rico�s energy sector. According to Luma, part of that
money is currently being used to replace outdated breakers like the one
that blew up at the Costa Sur generation plant.

In a news conference Thursday afternoon outside the damaged power plant, a
Luma Energy official said many of the breakers being replaced are over 40
years old � though this piece of equipment normally has a 30-year
lifespan.

The Puerto Rico Electric Power Authority is still in the process of
restructuring its $9 billion in public debt, the largest of any U.S.
public corporation when it declared bankruptcy in 2017.

This is not the first time that power station fires have caused blackouts
in Puerto Rico. Last June, a large fire at a substation in San Juan left
900,000 customers without power. Another fire at a power plant in
September 2016 caused an islandwide blackout.
