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.

Current activities are funded through an interagency agreement with the Federal Emergency Management Agency. The DOE Office of Electricity and Solar Energy Technologies Office have funded past activities.

PR100 1-Year Progress Update

Text version

Ongoing 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 will provide 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 will demonstrate how technologies for energy storage, distributed generation, distribution control, electric vehicles, and energy-efficient and responsive loads can provide reliable, affordable, and resilient electricity to all of Puerto Rico's cities and communities. The final clean energy scenarios will account for a climate risk assessment, economic impacts, and feedback from an advisory group representing diverse perspectives from the community and energy sector stakeholders.

For Puerto Rico, we are working to deliver tool enhancements, hands-on support with energy system modeling and scenarios, short-term and day-ahead resource forecasts, and storm checklists for solar systems.

PVWatts Calculator

We have developed a Spanish version of the PVWatts Calculator. Follow the link and click "Español" in the top navigation bar.

System Advisor Model

We have updated the System Advisor Model (SAM) with mini-grid capabilities relevant to Puerto Rico systems and developed Spanish versions of the following SAM resources:

Introducción a SAM (Modelo para Asesoría de Sistemas)

Guía de introducción del SAM BORRADOR

SAM template file.

Engage Tool

We are 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.

Solar Resource Data

We have developed solar resource data for Puerto Rico. Also, we are developing a capability to deliver 2-km, 5-min resolution solar resource data in near real-time and additional enhancements using next-generation satellite data. Intended use is for net-load forecasting dispatch in Puerto Rico and, more generally, as day-ahead forecasts for specific periods as required by NREL researchers conducting modeling and analysis for Puerto Rico.

Preparing Solar Photovoltaic Systems Against Storms

We created 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. The storm-hardening checklists provide preparation actions that can increase the chances that solar photovoltaic systems are available when communities need them most. 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.

El recurso completo también está disponible en español, 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.

We aim to deliver for Puerto Rico a modeling and simulation framework to analyze distributed energy resource (DER) regulation strategies, key considerations for microgrid technical requirements, field-implementation solutions and simulation results for hybrid plants, and potential scenarios for solar and storage adoption.

Voltage Regulation Strategies

We are Investigating voltage regulation strategies for DER with a focus on inverter-based DER technology types to illustrate functionality for determining performance categories and settings for voltage regulation modes. This will assist the Puerto Rico Electric Power Authority in the utilization of DER voltage and reactive power control capabilities supported by IEEE Std. 1547-2018.

Microgrid Technical Requirements

We are developing microgrid technical requirements consistent with IEEE Standard 1547-2018, including considerations for potential pilot demonstrations at multiple scales. This includes developing a modeling and simulation framework focused on inverter-based DER technology types and capabilities supported by the IEEE standard.

Hybrid Power Plants

We are conducting analysis to identify the potential of hybrid power plants—utility-scale wind or solar facilities co-located with battery storage—to improve the reliability and resilience of the power systems in Puerto Rico as well as optimal sizes and locations for co-virtual hybrid plants.

Solar and Storage Adoption Scenarios

We are developing scenarios of solar and storage adoption in Puerto Rico using NREL's Distributed Generation Market Demand model and Puerto Rico Energy Efficiency Scenario Analysis Tool, a spreadsheet tool developed to analyze the potential for DER and demand response to provide resilience, flexibility, and consumer benefits.

Water Treatment Plant Resilience

We will conduct modeling and analysis on resilience of wastewater treatment plants to power outages to identify opportunities increase resilience and ensure safe water conditions.

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

Past Activities

Key activities included:

  • Delivering high-resolution 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
  • Developing accessible end-user, cost-benefit tools with training sessions aimed at ensuring robust, data-driven investment decisions across Puerto Rico
  • Engaging with stakeholders to understand local energy planning needs and provide information about the multi-lab effort and results through workshops in San Juan and Mayaguez in March and a webinar series in the fall.

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."
