A 289-unit Medford development designed to meet the 20% EV code with one panel instead of three

The Clayborn is a 289-unit development on a former Medford, MA industrial site, with 318 parking spaces and a requirement to comply with the city's Specialized Energy Code, which calls for 20% of spaces to be EV-installed. The project is in pre-construction planning.

A conventional approach to that code target would size the electrical service for many ports charging at once, adding multiple large panels, more switchgear, and more construction complexity before a single resident plugs in.

PlugOp ran an Automatic Load Management System (ALMS) analysis to model real charging demand across the garage rather than assuming every port draws full power at once. That analysis supported a 66-port layout served by a single 400A panel instead of three.

The work combined value engineering, energy management, and code compliance, and reviewed utility incentive pathways to evaluate during construction. Figures reflect the pre-construction design; the final installed configuration is confirmed as the project is built.

Meeting the 20% EV-installed code with one 400A panel instead of three reduces electrical infrastructure, switchgear, and coordination in the build, without lowering the number of code-required ports.

Because load management shapes the design from the start, the same 66-port target is delivered on a leaner electrical backbone that still has room to manage demand as resident charging grows.
