A Distributed Energy Amenable Grid

Puerto Rico has the opportunity to rebuild its grid in a manner that makes the island more resilient. We find that PREPA can take action now to lay a strong foundation for distributed energy resources (DER) to integrate with the transmission & distribution system by making the right kind of capital equipment investments as it is being rebuilt. The future grid should be designed to accommodate far greater penetration of DER and ought to have the functionality to utilize DER as dynamic assets, supporting the grid. If PREPA fails to take actions to accommodate DER and beneficially utilize their grid support capabilities, it could face grid defection, and forego opportunities to significantly improve grid performance, productivity, and system resiliency.
