San Juan.- About 250,000 customers of electric service in Puerto Rico were affected this Thursday by a blackoutafter two units of the Costa Sur generating plant of the Electric Power Authority (AEE) in Guayanilla (southwest) went out of service.
The system crash occurred at 03:50 (07:50 GMT), “when the operator of units 5 and 6 of Costa Sur lost control of the 2 units, causing both to go out of service,” explained PREPA, led by Josué Colón, on their social networks.
Colón, for his part, explained in a radio interview with WKAQ-580 AM that one of the units had an “abrupt change in load or power demand that served, which caused, for a reason that is under investigation, that the boiler level was lost” and the other unit “lost control of the boiler emissions”.
“As a result of that event, around 250,000 customers were affectedColon specified.
However, at 06:27 (10:27 GMT) “more or less, all clients were restored thanks to the units of Cambalache, Mayagüez, Palo Seco, Daguao and unit 72 of Ecoelectrica,” said Colón.
According to Colón, the incident “reflects two things: the importance of having reservations“, that “we are an isolated system” and that “we continually indicate that it is important to repair the units, that it is important that we have backup units”.
“We have notified the Energy Bureau on multiple occasions, how important it is for an isolated system like Puerto Rico’s to have ‘blackstart’ and reserve units that may be available when these situations occur,” he specified.
Meanwhile, the company Luma Energy, in charge of the transmission and distribution of electrical energy in Puerto Rico, reports on its website that 96% of the subscribers of the network on the island have the service.
The remaining 4% wait for it to be restored the service affected by the passage of Hurricane Fiona last September 19.
Most of the customers who still do not have electricity are residents of the southwest and west of Puerto Rico.

Given this, Luma Energy assured that by this Thursday that remaining 4% will already have electric service, although yesterday, Wednesday, the assistant secretary of the Government of Puerto Rico for Energy Affairs, Francisco Berríos, affirmed that no later than next Saturday it will be the date for it.
