San Juan, Puerto Rico, June 23, 2021 – According to its contractual responsibility and commitment to be prepared to manage any emergency that would affect the electricity transmission and distribution system in Puerto Rico, LUMA developed an Emergency Management Plan. A copy of said plan was delivered to the Authority for Public-Private
Partnerships, the Puerto Rico Energy Bureau and to the Legislative Commissions that have requested it.

LUMA has been ready since June 1 to respond to Puerto Rico in an emergency. In fact, this happened on June 10 after the incident that caused a large fire in the Monacillo substation, an emergency to which LUMA responded effectively, managing to restore service to affected customers in 26 hours.

The company has the resources, manpower, and knowledge to serve Puerto Ricans in any
scenario that affects the system.
