This report, developed by the National Renewable Energy Laboratory (NREL) through the Global Power System Transformation (G-PST) Consortium, in collaboration with Coordinator Eléctrico Nacional (CEN), examines potential updates to Chile’s grid code for inverter-based resources (IBRs). As Chile transitions to a power system dominated by wind and solar, the document explores optimal approaches for adapting the grid to meet future energy demands.
The analysis compares Chile’s current grid code (NTSyCS) with those of Ireland’s EirGrid, the UK’s National Grid Electricity System Operator (NESO), and the IEEE 2800-2022 standard. It proposes technical requirements for conventional IBRs to be integrated into the Chilean grid code, addressing the challenges of an IBR-dominated grid.
Serving as a guide for future grid code updates, this report highlights the necessary technical requirements and IBR advancements needed to support Chile’s renewable energy transition. The project was made possible through funding from the U.S. Department of Energy.
