Rappahannock Electric Cooperative (REC) understands the increasing trend of vehicle electrification across the United States is causing electric utilities to review, identify and even change operating procedures to provide the energy needs of Electric Vehicles (EV). REC engaged 1898 & Co. to assess the impact that EVs will have on the distribution system caused from EV adoption and charging. The team worked together to forecast EV adoption, identify EV types and load profiles, and evaluate grid impacts and the investments required to support increased EV adoption on selected distribution circuits serving REC members.
As part of the analysis, the team assessed whether a specific member’s service, specifically the distribution service transformer, was ready to support EV charging. The team looked at historical loading conditions of transformers to predict individual service limitations and future accommodations from EV charging.
During this presentation, you will learn how the team:
- Identified upgrades required to support EV load at different penetration level
- Analyzed distribution transformer size changes
- Identified member service limitations
- Forecasted EV Charging Load to Members
