The new positions, all being filled by local Puerto Ricans with decades of critical industry and professional experience working in and for Puerto Rico, come four months after Juan Saca was named Chief Executive Officer of LUMA on July 1. 

“Since my first day at LUMA, I’ve been focused on attracting and promoting the very best, including identifying strong, local talent to join the over 4,000 members of our LUMA team who are building a better energy future for Puerto Rico,” said Juan Saca, President and CEO of LUMA.

Each of the new officers will help ensure that LUMA is operating at the highest ethical, legal, regulatory, and internal standards, and will provide additional expertise and knowledge to a diverse leadership team that has already made historic progress since assuming operations on June 1, 2021. Among some of its most notable accomplishments during LUMA’s first two years of operations include: reducing service interruptions by 35% in the first two years of operations, accelerating the clean energy transformation by connecting more than 71,000 customers to rooftop solar panels and initiating 411 FEMA projects, representing $11.7 billion, the largest investment made by the federal government in Puerto Rico.  

“All of us at LUMA are excited about the energy future we are building for Puerto Rico, and it is even more exciting when local Puerto Ricans join an already amazing leadership team. Working together, and remaining focused on our mission, we will continue to transform and modernize Puerto Rico’s energy future for the better,” said Saca.
