EVSE Deployment and Grid Evaluation (EDGE)

<p><font size='3'>The EVSE Deployment and Grid Evaluation (EDGE) Tool is
a mapping and visualization tool that provides the ability for users to assess
the feasibility of deploying charging infrastructure in the context of local
grid constraints.</font></p><p><font size='3'>EDGE
inputs information from two sources:</font></p><p></p><ul><li><font size='3'><b>California Investor-Owned Utility (IOU) Grid Needs Assessment (GNA) datasets</b> - The GNA data provide information regarding the amount of &quot;headroom&quot;
that primary circuits and substations have to accommodate new load before
requiring attention, such as equipment upgrades. Notably, there is no
information present regarding the secondary distribution system. The GNA
dataset EDGE currently uses is forecasted through 2025.</font></li><li><font size='3'><b>Results from the <a href='https://www.energy.ca.gov/data-reports/reports/electric-vehicle-charging-infrastructure-assessment-ab-2127' target='_blank' rel='nofollow ugc noopener noreferrer'>CEC's AB 2127 Assessment</a> Infrastructure Models, EVI-Pro and HEVI-LOAD</b> - Hourly load profiles from both models are combined and their overall peak values are assessed.</font></li></ul><div><font size='3'>The main result presented by EDGE is the capacity indicator metric (CIM), which is obtained by subtracting the peak EV charging load from the aggregated circuit capacity value for each TAZ throughout the state.</font></div><div><font size='3'><br /></font></div><div><i><font size='3'>Data last updated on 8/10/2023.</font></i></div><p></p><p><br /></p>
