After Tropical Storm Ernesto recently brought heavy rain and strong winds to Puerto Rico, LUMA announced that its round-the-clock efforts have restored power to 257,000 customers over the last 24 hours. As of 8 a.m. AST on Aug. 16, about 1.2 million customers have power in Puerto Rico, with about 257,000 customers without power due to the impact and effects on the electrical infrastructure from Tropical Strom Ernesto.
Recent Power Outages in Carolina and Eastern Puerto Rico
In the utility's ongoing restoration efforts, LUMA experienced two events on the evening of Aug. 15 that led to power outages affecting about 4,500 customers. The first incident occurred at the Cerámica Substation in Carolina, where a fire broke out on the metal-clad switchgear during energization. The second event involved a downed wire on a transmission line, impacting nearly 70,000 customers in the eastern part of the island. The utility is actively addressing both incidents, which will be resolved Aug. 16.
Global Estimated Restoration Timeframe Released
Following the completion of 672 damage assessments and aerial helicopter patrols, LUMA released its global estimated timeframe for restoration where 90% of customers may be restored by Aug, 18. LUMA will also soon announce estimated restoration times for each service region, once crews complete their remaining damage assessments of the electric system and are better able to determine the full extent of the damage to the system across specific communities and regions throughout Puerto Rico.
Coordination and Communications with Mayors
As part of LUMA’s commitment to communicating and coordinating preparation and restoration efforts before, during, and after the storm, the company has been actively engaging with mayors and municipal leaders daily as they are vital to supporting LUMA crews working to restore power to customers. These outreach efforts include 18 regional meetings with mayors and members of their teams and more than 705 direct contacts with municipalities since activating its emergency response on Tuesday.
“While over 257,000 of our customers have been restored in the last 24 hours, we are now prioritizing the areas and our customers without power," says said Juan Saca, LUMA president and CEO. "Our crews are working tirelessly, in difficult conditions, to restore power and make critical repairs as quickly and safely as possible, especially in the areas of San Juan and Caguas as well as the islands of Vieques and Culebra – areas which saw the greatest impacts from the storm. We will continue to share regular updates with our customers and will continue to communicate and coordinate with our municipal leaders on our overall restoration efforts,”
