Results of the PR100 study outline near- and short-term strategies for Puerto Rico to achieve a renewable power grid by 2050

SAN JUAN, Puerto Rico—With lots of solar and wind power, energy storage, and advanced extreme weather impact modeling, Puerto Rico could achieve a 100% renewable power grid by 2050. These and other recommendations are the results of the Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study (PR100), announced today.

For the last two years, six Department of Energy national laboratories, with extensive input from stakeholders in Puerto Rico, studied how the island can build a renewable, resilient grid.

Pacific Northwest National Laboratory researchers led much of the resilience and reliability modeling for the study. In one portion of the study, researchers simulated a future renewables-based power grid using the Electrical Grid Resilience and Assessment System (EGRASS) model—and then hit it with 100 hurricanes to analyze the system recovery after severe damage with the Recovery Simulator and Analysis model. They also looked at how technologies such as grid-forming inverters would help create a more reliable grid.

“We’re in a position now to help Puerto Rico be in control of their renewable energy efforts as they progress toward a 100% renewable, resilient grid,” said Marcelo Elizondo, principal electrical engineer at PNNL and lead researcher on PNNL’s contributions to the PR100 study.

The study results outline both near- and short-term strategies for Puerto Rico to build a resilient, reliable grid in the face of major hurricanes and natural disasters. The results emphasize accelerating deployment of renewable energy generators such as rooftop solar panels, the critical need for energy storage to stabilize the grid in case of a disruption in energy generation and enhanced extreme weather impact modeling to prepare for hurricanes.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it!! So, we've decided to completely nix paywalls here at CleanTechnica. But...
