Marcha del Sol: Adjuntas Celebrates Casa Pueblo’s Microgrid Serving the Community 

On March 18, residents of Adjuntas came together for the Marcha del Sol, a celebration of the installation of solar-powered microgrids to combat frequent and sometimes long-lasting blackouts in the community. Using funding from the Honnold Foundation, local nonprofit Casa Pueblo connected more than a dozen Adjuntas businesses to microgrids using solar panels and batteries. These technologies are being enhanced with technical assistance through the University of Puerto Rico at Mayagüez and DOE’s Oak Ridge National Laboratory (ORNL), which is currently working on a new energy resilience technology known as a microgrid orchestrator. This innovation will allow neighboring grids to communicate and export energy to each other, enhancing microgrids’ reliability even when damaged. While this new technology could have remarkable impacts in Puerto Rico, it also holds broader potential for the global future of microgrid resiliency and reliability.

ORNL is also one of the DOE laboratories supporting PR100 through computer modeling and stakeholder engagement. Visit ORNL’s website for more updates about the lab’s microgrid research.
