Third-Party Case Study
A 600-unit Columbus community built assigned and shared EV charging into new construction
For a new Class A apartment community in Columbus, PlugOp supplied 18 Level 2 charging ports and load-management software across a six-floor garage. The design met the city's installed-charging requirement while creating a more cost-effective model for assigned resident parking.

This page is based on a Charge at Home case study
Charge at Home is a U.S. Department of Energy-supported multifamily EV charging program led by Forth in collaboration with the National Multifamily Housing Council and other national transportation-electrification partners. Its original one-page case study documents the property, charging design, project financials, installation process, and resident feedback.
01
The project
N.P. Limited Partnership / Polaris Centers of Commerce developed the 600-unit, mid-rise apartment community with a six-floor garage containing 737 parking spaces. The new-construction project was completed in the third quarter of 2025.
Columbus requires a portion of parking in new construction to include EV infrastructure. The project was designed to meet the local requirement for 2% of spaces to have installed EV supply equipment and 20% to be EV-capable, with ADA requirements addressed through building-code compliance.
02
The charging design
PlugOp supplied 48A Level 2 chargers and load-management software. Floors 1, 2, 3, 5, and 6 each received two shared chargers on a dedicated 60A circuit, creating 10 shared charging spaces across the garage.
Floor 4 received eight assigned chargers. Two 60A circuits each serve four ports through load management, allowing the project to scale charging access without sizing every port for simultaneous full-power demand or requiring major electrical upgrades.
03
Cost and operations
The assigned chargers cost $3,000 per port for equipment and installation, compared with $5,095 per port for the shared chargers. No financial incentives were used. Because the charging scope was integrated into the new building, the project required no retrofit and stayed aligned with the construction schedule without notable delays.
Oakwood Management manages the chargers, software, and management platform. During lease-up, residents were already requesting access to assigned charging, which Charge at Home cited as an early signal that at-home charging access supported leasing demand.
