Puerto Rico’s LUMA Connects 330 MW in Rooftop Solar Power

April 24, 2023

LUMA supported more than 54,000 customer connections to rooftop solar, representing a milestone in its ongoing efforts to advance clean energy in Puerto Rico.

This connection of more than 54,000 customers in 21 months represents 330 MW of additional renewable energy connected to the grid during LUMA’s time as the operator of Puerto Rico’s electric system.

As a result of this progress, Puerto Rico now ranks seventh among all U.S. states and territories in residential solar energy adoption per capita, according to net metering data from the U.S. Energy Information Administration (EIA).

In the 21 months since LUMA assumed operations of the electric system, the number of interconnected residential solar customers has tripled compared to what was achieved in the previous decade – growing from approximately 24,000 to over 78,000 total solar connections. This success is due in part to LUMA’s accelerated solar connection program that provides customers with shorter wait times for approval and has increased customer connections to an average of 3,400 each month.

In addition to advancing more home solar connections for customers, LUMA is working to safely and reliably interconnect more than 1,300 MW of utility-scale renewable generation to Puerto Rico’s electric grid. LUMA is also working closely with the Federal Emergency Management Agency (FEMA), the U.S. Department of Energy (DOE), and the Puerto Rico Energy Bureau (PREB) to achieve a more resilient and cleaner energy system.
