Electrification Impact Analysis
Objective
To address impacts of the California Clean Transportation Plan on the transmission and distribution (T&D) system from high levels of EV adoption. Our customer needed to know where and when the impacts would be on their system, along with the magnitude.
Approach
Through our proven process, we estimated the impact of medium- and heavy-duty (MDHD) fleet charging using multiple data sets for accurate analysis.
- Locate fleet facilities and vehicle counts at the address level.
- Categorize the facilities into groups based on vehicle type, usage patterns, and energy needs to create load profiles.
- Aggregate the 8760-hour load profiles to generate a system-wide profile for distribution planning and load mitigation.
Results
We displayed four key findings in our report:
- 2040 peak load is 75% higher than previous estimates.
- MDHD load is not evenly distributed and requires an address-level analysis to accurately estimate the grid impact.
- Total load is sensitive to available charging windows, dwell time, and EV energy requirements.
- Accurate analysis requires a variety of datasets for MDHD.
Our proprietary five step plan locates system impacts due to electrification, profiles those loads and maps them to system assets, such as feeders and substations. We then develop mitigation plans and can provide regulatory support.
