Multilab Energy Planning Support for Puerto Rico

NREL provides Puerto Rico stakeholders with tools, training, and modeling support to enable planning and operation of the electric power grid with more resilience against further disruptions.

Since Hurricane Irma and Hurricane Maria in September 2017, NREL has partnered on this effort with the U.S. Department of Energy (DOE) and other national laboratories:

  • Argonne National Laboratory
  • Lawrence Berkeley National Laboratory
  • Oak Ridge National Laboratory
  • Pacific Northwest National Laboratory
  • Sandia National Laboratories.

Activities are funded through an interagency agreement with the Federal Emergency Management Agency (FEMA); past activities were funded by the DOE Office of Electricity and Solar Energy Technologies Office.

New U.S. Department of Energy and Federal Emergency Management Agency Technical Assistance for Puerto Rico's Grid

We are supporting a new portfolio of technical assistance projects from FEMA and the DOE to support the modernization of Puerto Rico’s electric grid for Puerto Rico.

  • Support for disaster preparedness by enhancing usability of the Electrical Grid Resilience and Assessment System and the Recovery Simulator Analysis tool
  • Training for stakeholders on the PR100 results
  • Siting opportunities for new generation projects
  • Innovative programs to improve reliability and resilience
  • Supply chain and infrastructure analysis
  • Integrated transmission and distribution planning
  • Impacts and mitigation strategies for high penetration of distributed generation
  • Assessment of Puerto Rico Integrated Resilience Plan
  • Support implementation of Community Development Block Grant funding for the grid

Past Activities

Puerto Rico has committed to meeting its electricity needs with 100% renewable energy by 2050. In a 2-year study, NREL and a team of five other national labs provided Puerto Rico's decision makers and planners with the advanced grid analysis and cross-sector modeling support to generate feasible pathways for their clean energy transition. The PR100 study concludes that it is feasible for Puerto Rico to achieve 100% renewable energy by 2050, and significant system upgrades and investments—guided by meaningful community participation—are needed to get there. The study includes implementation actions stakeholders could take to achieve a more robust, reliable, renewable, resilient, and just energy system for Puerto Rico.

For more information, visit the PR100 Study.

Key activities included:

  • Developing solar resource data for Puerto Rico and the U.S. Virgin Islands through the National Solar Radiation Database
  • Delivering models of Puerto Rico using grid modeling tools—Flexible Energy Scheduling Tool for Integrating Variable Generation and Multi-Area Frequency Response Integration Tool—and training models on real data
  • Developing and executing an educational module that provides analytical support to stakeholders on best practices for interconnection of distributed energy resources and IEEE 1547 standard
  • Delivering Puerto Rico-specific SAM improvements to provide foundational solar profiles for production cost modeling and to enable stakeholders to perform detailed cost-benefit analysis of renewable energy systems, accounting for resiliency and ancillary service functionality
  • Providing support for use of the Engage™ tool as a convening hub for collaborative, user-driven capacity expansion planning in Puerto Rico, including energy system models, scenarios, and local capacity-building

  • Creating a set of pre-storm checklists for owners and operators of solar installations to help Puerto Rico and similar communities secure their assets in advance of severe weather. Designed with stakeholder input, the resource includes separate checklists for utility-scale ground-mounted PV systems, distributed roof-mounted PV systems, and distributed ground-mounted PV systems.

    In Spanish: Preparación de sistemas solares, incluyendo listas de verificación de refuerzo de tormentas individuales para sistemas fotovoltaicos montados en el suelo, sistemas fotovoltaicos montados en el techo, y sistemas fotovoltaicos de servicios públicos montados en el suelo.

  • Supporting Puerto Rico through effective information dissemination to stakeholders in the form of workshops and other resources and providing responsive capacity development in the form of on-demand technical assistance.

NREL provided Puerto Rico Electric Power Authority "… recommendations for a new framework of interconnection standards to accelerate the integration of utility-scale, transmission-connected renewable electrical generation and energy storage that ensure cross-technology compatibility and enable high deployment levels without compromising grid reliably, safety, or security."
