EV: Data-Based Transformer Replacement Sizing for EV Adoption

Date: August 2023

Increased EV adoption implies higher charging demand on the grid, impacting the thermal loading of distribution system assets. Appropriate sizing of replacement service transformers is critical. Presenters discuss a SMUD case study that compares two approaches: 1) Sub-meter and vehicle telematics data to construct EV charging load shapes, and 2) Grid topology with EPRI’s Hotspotter tool to evaluate the impact of replacement service transformer sizing.
