Substation Modernization - Progreso

Substation Modernization Initiative

LUMA is setting the standard for the modernization of all substations across Puerto Rico, beginning with 5 major substation modernization projects. Substations are vital to building a more reliable and more resilient energy system. That is why we have prioritized repairing substations that have suffered years of neglect.

Progress Points

LUMA has initiated the modernization of 300 substations across Puerto Rico.
Since June 2021, LUMA has restored three substations to operation — including one that had not been in operation since 2010.
$24.4 million in federal funding has been secured to begin the modernization of the more than fifty-year-old Cataño substation, which will serve as a model for other substation improvement projects.
In total, LUMA has announced six substation improvement projects, representing more than $47 million in federal funds.

At LUMA, we are committed to making infrastructure improvements every day to build the next generation electric grid that Puerto Ricans deserve.

As part of these efforts to increase system reliability, we’ve cleared over 30+ tons of vegetation from the 354 substations across the island. We’ve also restored three substations, including one that had not been in operation since 2010.

Substations connect transmission and distribution lines throughout the island, reducing the high voltage from transmission lines to low voltage distribution lines that bring power to homes and businesses.

Thanks to efforts like these, we’ve seen a decrease in the number of sustained outages experienced by the average customer by 18% from December 2021 to February 2022 when compared to the period of June-August 2021. Additionally, the average outage duration for each customer served also decreased, with an improvement of as much as 45% from June 2021 to February 2022.
