Open letter to our friends, families and neighbors,

This week marks an exciting milestone for LUMA as we celebrate six months of having the privilege to serve you.

Since we assumed operations of Puerto Rico’s transmission and distribution delivery system on June 1, 2021, we’ve been hard at work making progress every day to improve our service. Our team of more than 3,000 has been working hard to transform the island’s electric grid into a more reliable, more resilient and cleaner energy system.

In just the past six months, we’ve been able to make significant progress on critical actions to improve infrastructure repairs and upgrades, customer service and solar adoption. We will continue to move forward and advance our ongoing and concerted effort to build a world class energy system that Puerto Ricans deserve and can be proud of.

While there is much more work to do, we have proved in just six months how determined we are to build a more reliable, more resilient, safer and cleaner electric system for all of Puerto Rico.

Here is just a just a short list of ways we working to serve you and all of our customers better:

• Improving Customer Service: Improving customer service by reopening all 25 customer service centers and opening four new customer contact centers across Puerto Rico.
• Providing New Customer Tools: Launching new customer channels of communication, including a new website, the Mi LUMA app and social media channels.
• Empowering Renewables: Accelerating Puerto Rico towards a renewable energy future by connecting 12,000 new customers and 50 megawatts of solar power and supporting Puerto Rico’s “tranche 1” renewable procurement plan.

• Infrastructure Upgrades: Upgrading critical local infrastructure including more than 1,800 power poles and dozens of critical distribution breakers to reduce the likelihood of future outages.
• Clearing Vegetation: Improving resiliency by clearing hazardous vegetation from over 100 of our substations and restoring three substations — including one that had not been in operation since 2010.
• Clearing Old Debris: Clearing and properly disposing of almost 1 million pounds of trash, waste and debris that was left on operational sites and that impeded work.
• Improving Employee Safety: Conducting health and safety training for hundreds of our new LUMA co-workers and dramatically improving employee health and safety.
• Expanding the LUMA Team: Graduating the first class of Puerto Rican lineworkers from the LUMA College for Technical Training, bringing world-class training and development for the technical trades.

We are excited to share our accomplishments with you and are committed to continue to get better every day. We are proud of this work, and while we have started to build a more reliable and more resilient system, we know that there is more work to be done. This is just the beginning, and we will not stop until the job is complete.

We are thankful for the opportunity to work for you and wish you and your family a happy holiday season.

As always, if you have any questions, please call us at 1-844-888-5862. Our entire LUMA family is here for you 7 day a week, 24 hours a day.

Sincerely,

The LUMA Family
