Webinar: Long-Term Load and DER Forecasting Task Force Report

August 13 @ 4:00 pm - 5:00 pm EDT

  • « July 2025 i2X FIRST Meeting Copy
  • ESIG LLTF Webinar: Practical Guidance and Considerations for Large Load Interconnections Overview »

Featured Speaker: Julieta Giraldez, Director of Integrated Grid Planning, Electric Power Engineers (EPE)

Webinar Abstract: Long-term load and Distributed Energy Resource (DER) forecasting is critical for achieving clean energy and decarbonization goals, ensuring a reliable, resilient, and affordable energy system. In this webinar, we will present the findings of the “Long-Term Load and DER Forecasting” report, which represents the culmination of the work of the Energy Systems Integration Group’s (ESIG) Long-Term Load and DER Forecasting Task Force and addresses key forecasting issues in this transforming grid. It outlines key findings such as the need for high-resolution, time-based forecasts (8760 hourly profiles) to capture the correlated impacts of weather on demand, generation, and the nuances of DER behavior as well as existing challenges in reconciling system-level top-down and local bottom-up forecasts.

About the Speaker: Julieta Giraldez is a nationally and internationally recognized subject matter expert in distributed energy resource (DER) grid integration with extensive expertise in grid modeling and planning processes. She currently works at Electric Power Engineers (EPE) as a Director of Integrated Grid Planning where she implements holistic approaches to meet customers’ needs through the optimized planning and operation of generation, transmission, distribution, and distributed resources. Prior to joining EPE, she served as a Director of Grid Planning at Kevala Inc., where she focused on implementing proactive capacity planning and electrification impact studies for utilities and regulators. Julieta also worked for a decade at the National Renewable Energy Laboratory (NREL) as a Senior Engineer where she led Smart Grid and Grid Integration related projects to manage emerging technologies such as PV, energy storage and microgrids in distribution systems. She holds a bachelor’s degree from the Polytechnic University of Madrid (Spain) in Technical Mining Engineering, a master’s in electrical engineering from Colorado School of Mines, and a Ph.D. program in systems engineering from Colorado State University.
