Puerto Rico Webinar Series: Energy Planning Tools

This webinar from Sept. 26, 2019, focused on no-cost energy planning tools for Puerto Rico. 

It was one in a series of four extended webinars for Puerto Rico energy system planners offered in the fall of 2019 as part of NREL’s contribution to Multi-Lab Energy Planning Support for Puerto Rico.

Webinar Sessions

This 6-hour webinar featured the following sessions.

National Solar Radiation Database, Manajit Sengupta, NREL

Downscaled for Puerto Rico, the National Solar Radiation Database (NSRDB) is a serially complete collection of meteorological and solar irradiance data sets for the United States and a growing list of international locations. The data are publicly available at no cost to the user.

System Advisor Model and PVWatts, Nate Blair, NREL

This session provided an overview of the System Advisor Model (SAM), a free computer program that calculates a renewable energy system’s hourly energy output in a year, and the PVWatts Calculator, which included a section on photovoltaics (PV) and battery modeling.

REopt and REopt Lite, Emma Elgqvist, NREL

These tools answer the question, “What combination of solar PV, wind, and energy storage will help my site minimize energy costs or sustain a grid outage?” For Puerto Rico, only solar plus storage is supported for now, not wind.

Engage Tool, Tom Harris and Rob Spencer, NREL

This session was an introduction to NREL's web-based capacity expansion and production cost modeling application Engage™, also known as Hawaii Energy Visualization Initiative or HEVI, a platform for collaborative energy system modeling in Puerto Rico.

FAST Tools, Steve Folga, and Edgar Portante, Argonne National Laboratory

This session was about LNGfast, Telcofast, and future applications, as well as EPfast and the Palo Seco expansion analysis.

Environment for Analysis of Geo-Located Energy Information , Aaron Myers, Oak Ridge National Laboratory

The Environmental for Analysis of Geo-Located Energy Information (EAGLE-I) is an interactive geographic information system that provides energy sector situational awareness to the U.S. Department of Energy (DOE) Office of Electricity Delivery and Energy Reliability's Infrastructure Security and Energy Restoration (ISER) division. EAGLE-I is directed at supporting the ISER responsibilities associated with Emergency Support Function for Energy as it relates to the energy sector for the nation.

Also, see DOE’s EAGLE-I.
