PREPA Distribution Standards Project

TRC assists PREPA in developing Distribution Standards and Material Specifications resulting from the restoration efforts of Hurricanes Irma and Maria in 2017.


After the devastation brought about by Hurricanes Irma and Maria in 2017, Puerto Rico’s electric grid needed to be rebuilt and modernized. The Puerto Rico Electric Power Authority (PREPA) needed help to develop new overhead and underground distribution standards and material specifications to meet more stringent design criteria 



TRC developed design criteria to meet the wind loading, lightning, vegetation, contamination and loading requirements for new distribution lines to be rebuilt In Puerto Rico. The project required  converting all distribution lines to a standard 12 kV design so that all new lines are design and built to that voltage level. 


The distribution standards are in progress and PREPA has approved the initial draft of the overhead standards which are to be implemented in all new design projects in Puerto Rico. Work will continue to finalize the overhead and underground standards.
