Warning issued for Tuesday night
LUMA Energy warned on Tuesday, Oct. 27 that there is a high risk of rolling blackouts during peak consumption hours that night. Metro Puerto Rico reported. The company said available generation at Central San Juan and Aguirre could be insufficient to meet projected demand, which could force temporary service interruptions in some areas.
According to LUMA, coordination is under way with generating companies to increase energy availability and lessen the effect on approximately 100,000 customers. However, the measures do not guarantee that load shedding can be avoided, Metro Puerto Rico reported.

Cause of the shortfall
Primera Hora reported that LUMA stated in writing that, according to the most recent system data, a deficiency of approximately 311 megawatts is projected. The shortfall is caused by operational failures in units of Genera PR located at the San Juan and Aguirre plants. Primera Hora reported.
LUMA, which is responsible for transmission and distribution, said it remains in communication with the generating companies to monitor the units. The company urged customers to follow its official channels for updates on the status of the electric system.
Where the sources differ
Both Metro Puerto Rico and Primera Hora report that LUMA Energy warned of possible load shedding or rolling blackouts on the night of Tuesday, Oct. 27 due to insufficient generation capacity at San Juan and Aguirre.

Primera Hora adds that LUMA cited a projected 311 MW deficit caused by operational failures at Genera PR units. Metro Puerto Rico does not mention the 311 MW figure, Genera PR or the specific cause of operational failures.
