Siemens’ White Paper Outlines Design for Mini-Grids to Energize Puerto Rico
Siemens proposes 10 mini-grids that will cover most of Puerto Rico and will be designed to enhance resiliency to withstand or recover quickly from future natural disasters.
Design enhances reliance on renewables and exceeds the established renewables penetration goal by 15 percent.
Today, Siemens released its white paper, “Resilient by
Design: Enhanced Reliability and Resiliency for Puerto Rico’s Electric Grid,” which outlines a new energy infrastructure framework in the wake of last year’s Hurricane Maria....
