Puerto Rico Energy Efficiency Market Baseline and Potential Study

Published in
2025

The Government of Puerto Rico has established ambitious targets to increase electric energy efficiency by 30 percent by 2040 using an array of approaches. The primary purpose of this study is to provide the Puerto Rico Energy Bureau (PREB) and LUMA, the third-party operator of Puerto Rico’s transmission and distribution system, with an assessment of the energy efficiency market in Puerto Rico to inform both near-term program design and longer-term strategies for program scaling and prioritization.

This study provides three primary components:

  1. A characterization of Puerto Rico's current building stock and market for energy efficiency,
  2. An estimate of current and future savings from non-utility programs and policies, and
  3. An estimate of the potential for electric energy savings and peak demand reduction through utility-run energy efficiency programs over a 15-year period spanning FY2026 through FY2040.
