How to Manage an EV Charging Infrastructure Rollout

The Problem: EV Charging Rollouts Fail on Coordination, Not Technology

Enterprise EV charging deployments — whether across a corporate fleet depot, a retail network, or a municipal parking system — look deceptively simple on paper. Buy chargers, hire an electrician, plug them in. In practice, the coordination complexity rivals a small construction project: utility service upgrades, permitting from multiple authorities, make-ready civil work, network connectivity, and software integration with fleet management systems all have to land in the right sequence.

Organizations that try to manage EV charging rollouts with email chains and informal checklists routinely hit the same failures: utility service upgrade lead times of 6–12 months that weren't anticipated, permit delays from AHJs unfamiliar with Level 2 or DCFC requirements, and EVSE equipment that arrives on site before electrical make-ready work is complete. The result is equipment sitting in a warehouse for months, vehicles still charging from extension cords, and frustrated executives asking why the project is over budget.

A phased EV charging infrastructure Gantt chart built in gantt-chart.io gives program managers, facility teams, and utility contacts a shared timeline that surfaces dependency conflicts before they cause delays.

Prerequisites

Site electrical demand assessment completed (load study)
Utility tariff and interconnection requirements identified for each site
EVSE equipment vendor selected (or RFP issued)
Permitting requirements confirmed with AHJ for each location
Network connectivity options assessed (cellular, Wi-Fi, Ethernet)
Funding source identified (NEVI, utility rebate, corporate capex, or EVSE-as-a-service)

EV Charging Infrastructure Rollout Template

Phase 1: Site Assessment and Design (Weeks 1–8)

[ ] Conduct electrical capacity assessment at each site (panel capacity, transformer rating)
[ ] Complete site walk and parking layout survey for charger placement
[ ] Determine charger type and quantity per site (Level 2 vs. DCFC)
[ ] Identify conduit routing, trenching requirements, and switchgear location
[ ] Submit utility load growth application and service upgrade request
[ ] Develop single-line electrical diagrams for permit submission
[ ] Confirm ADA accessibility compliance requirements for each charger location

Phase 2: Permitting and Utility Coordination (Weeks 6–24)

[ ] Submit building permit and electrical permit applications to AHJ
[ ] Apply for utility make-ready program or submit transformer upgrade request
[ ] Coordinate utility inspection scheduling for metering changes
[ ] Apply for NEVI or state EV infrastructure grant funding (if applicable)
[ ] Secure fire marshal review if DCFC installation in enclosed structure
[ ] Obtain utility interconnection agreement for demand response participation
[ ] Confirm permit approval timeline and schedule inspection milestones

Phase 3: Equipment Procurement and Network Setup (Weeks 12–24)

[ ] Execute EVSE purchase order with hardware vendor
[ ] Procure switchgear, panels, conduit, and wiring materials
[ ] Set up charging network account and configure back-end management system
[ ] Configure OCPP (Open Charge Point Protocol) integration with network operator
[ ] Establish network connectivity infrastructure (cellular SIM or Wi-Fi access points)
[ ] Integrate EVSE network with fleet management or payment platform
[ ] Receive equipment on site and verify against purchase order

Phase 4: Civil and Electrical Make-Ready (Weeks 20–36)

[ ] Mobilize electrical contractor for make-ready work
[ ] Complete trenching, conduit installation, and concrete work
[ ] Install dedicated circuit breakers, panels, and service upgrade equipment
[ ] Complete utility service upgrade and new meter installation
[ ] Install bollards, signage, and ADA-compliant accessibility features
[ ] Pull wire, terminate connections, and label circuits
[ ] Complete rough electrical inspection with AHJ

Phase 5: EVSE Installation, Commissioning, and Launch (Weeks 34–44)

[ ] Mount and wire EVSE units per manufacturer specifications
[ ] Activate network connectivity and register units on charging network platform
[ ] Complete final electrical inspection and obtain certificate of occupancy
[ ] Conduct user acceptance testing: initiate, authenticate, and complete test charges
[ ] Train facilities staff on EVSE operation, troubleshooting, and escalation procedures
[ ] Launch driver communications and publish charger locations to PlugShare/AFDC
[ ] Activate utility demand response program enrollment (if participating)

Common Mistakes

Ignoring utility lead times: Transformer upgrades and new service drops from utilities routinely take 6–12 months. This is almost always the critical path item and must be initiated in Week 1, not after permits are approved.
Mixing charger levels without load management: Installing multiple DCFC units on a site without load management software causes demand charge spikes that can double electricity costs.
Skipping ADA review: ADA requires specific accessible route widths and charger reach range compliance. Retrofitting non-compliant installations is expensive and can trigger permit revocation.
No network redundancy plan: Cellular-only EVSE units in underground garages or metal-clad buildings frequently have connectivity issues. Plan for failover modes during network outages.

Timeline Summary

Phase	Duration	Key Milestone
Site Assessment	Weeks 1–8	Load study complete, charger layout finalized
Permitting & Utility	Weeks 6–24	Permits approved, service upgrade ordered
Procurement & Network	Weeks 12–24	Equipment ordered, network configured
Make-Ready	Weeks 20–36	Electrical rough-in complete, utility meter installed
Installation & Launch	Weeks 34–44	Chargers live, drivers notified

Next Steps

EV charging rollouts at scale — across 10, 50, or 500 sites — require project management infrastructure that can track site-by-site progress while showing portfolio-level status. Build your EV charging infrastructure timeline on gantt-chart.io, assign site leads to each location, and give utility contacts and permitting teams shared visibility into where each site stands in the queue.
