Strengthening Puerto Rico’s Power Grid

Following hurricane damage, Navigant contributes to a new report on reimagining and rebuilding Puerto Rico’s power system

In September, Hurricane Maria severely damaged Puerto Rico’s electric power system. As efforts to restore power and repair the grid continue, governors Andrew M. Cuomo of New York and Ricardo Rosselló of Puerto Rico have announced a plan for rebuilding aimed at increasing resilience and efficiency, while reducing the island’s dependence on fossil fuels.

The plan is detailed in a new report, which Navigant contributed to. Build Back Better: Reimagining and Strengthening the Power Grid of Puerto Rico offers a road map outlining short-term, mid-term, and longer-term actions to implement system hardening designed to increase the resiliency of Puerto Rico’s electric power grid. Recommendations include the modernization and transformation of the grid, as well as leveraging proven power system technologies to better contain outages, reduce recovery times, lower operation costs, and enable more sustainable energy resources to reduce reliance on costly imported fuel. 

Additionally, the report calls for the use of increased renewable energy resources, such as wind and solar, and the incorporation of new distributed energy resource (DER) technologies, such as energy storage and microgrids.

Navigant helped form these recommendations by providing expertise in the areas of generation, transmission and distribution, and DER. Our efforts supported system data collection and analysis, and provided a definition of redesign criteria, systemwide rebuild recommendations with costs and timeline estimates, and project leadership for report coordination and development.
