Start with limits: Design for today’s grid and future-proof for
tomorrow’s upgrades. The site currently has chargers and plans to
scale 60, for combined nameplate charging capacity nearly 12

segregate downstream chargers powered different energy
sources. Combining them will help manage
peak loads more effectively and provide energy resiliency.The site features
multiple levels load control, including ABB’s Supervisory Control and
Data Acquisition (SCADA) platform, which acts backup the
Charger Management System (CMS). Each transformer feeds dedicated switchboard, which
distributes power each charger its group.The site’s chargers are organized into four groups—each
