Electric vehicle adoption is accelerating faster than most forecasts predicted. Organizations across sectors—from commercial real estate to municipal fleets, from retail destinations to logistics operations—must now plan for EV charging infrastructure with strategic rather than experimental approaches.
This guide provides a comprehensive framework for EV infrastructure planning, addressing the decisions that determine whether investments deliver value over their multi-decade lifespans.
The EV Infrastructure Opportunity
Drivers of EV Adoption
Several forces are accelerating EV transition:
Policy mandates: Clean fleet requirements, emission standards, and ZEV mandates create regulatory pressure.
Total cost of ownership: Despite higher upfront costs, EVs increasingly compete on total cost as fuel and maintenance savings accumulate.
Corporate sustainability: ESG commitments and sustainability goals drive fleet electrification.
Consumer preference: Growing consumer preference for EVs influences customer-facing decisions.
Technology maturation: Battery cost declines, range increases, and charging speed improvements reduce adoption barriers.
Infrastructure Imperative
EV adoption requires charging infrastructure. Without convenient charging, EVs don't work. Organizations must plan infrastructure for:
Fleet electrification: Vehicles returning to depots need overnight charging. Field charging supplements depot infrastructure.
Employee and customer amenities: Workplace and destination charging supports stakeholder needs and attracts users.
Revenue opportunity: Public charging creates revenue streams for property owners and retailers.
Real estate value: Properties without charging may become less attractive as EV adoption grows.
Strategic Framework for EV Infrastructure
Phase 1: Strategic Assessment
Before selecting chargers, establish strategic foundations:
Use case definition:
Who will charge?
- Fleet vehicles (depot charging)
- Employees (workplace charging)
- Customers (destination charging)
- Public (revenue charging)
What are their needs?
- Daily driving patterns and charging requirements
- Dwell time (how long vehicles are parked)
- Expected charging frequency
- Mix of BEV and PHEV
What vehicles?
- Current fleet vehicles
- Planned acquisitions
- Personal vehicles of employees/customers
- Charging connector and power compatibility
Demand forecasting:
Near-term: Current and planned EVs requiring charging.
Medium-term: Expected EV adoption based on policy, technology, and market trends.
Long-term: Scenario planning for different adoption trajectories.
Demand forecasting should inform both how many chargers and what infrastructure capacity to install (infrastructure can be installed for future chargers to avoid re-excavation).
Phase 2: Site Assessment
Physical site characteristics shape infrastructure options:
Electrical infrastructure:
Existing capacity: Available electrical capacity at service entrance and distribution points.
Upgrade requirements: If existing capacity is insufficient, what upgrades are needed at what cost?
Utility coordination: Utility review may reveal system constraints or upgrade timelines.
Physical layout:
Parking layout: Location of parking relative to electrical service.
Civil work: Trenching, conduit, concrete work requirements.
Accessibility: ADA compliance, access for charging equipment installation and maintenance.
Future expansion: Space and conduit for additional chargers.
Operational considerations:
24/7 access: For public or fleet charging, access requirements.
Security: Lighting, surveillance, and safety considerations.
Payment and access control: How access will be managed.
Phase 3: Technology Selection
Charging technology choices have long-term implications:
Charging level selection:
Level 1 (120V): Slow charging (3-5 miles of range per hour). Suitable for overnight parking of PHEVs or light-use BEVs.
Level 2 (240V): Standard charging (10-30 miles per hour). Appropriate for most workplace and destination applications.
DC Fast Charging (DCFC): Rapid charging (100-350+ miles per hour). Necessary for high-turnover applications, fleet operational charging, or public charging stations.
Infrastructure design considerations:
Load management: Systems that dynamically allocate power across chargers to maximize utilization within power limits.
Network connectivity: Chargers connected to backend for monitoring, payment, and management.
Interoperability: Compatibility with vehicle types and payment methods.
Futureproofing: Infrastructure capacity for potential upgrades (higher power chargers).
Vendor and equipment selection:
Reliability: Uptime performance in real-world deployments.
Service and support: Availability of maintenance and support.
Software capabilities: Fleet management, reporting, and integration features.
Total cost: Equipment, installation, and ongoing costs combined.
Phase 4: Grid Integration
Electricity infrastructure must support charging loads:
Utility engagement:
Early coordination: Engage utility during planning to understand capacity, timelines, and costs.
Rate optimization: Select rate structures that minimize charging costs (time-of-use, demand charges).
Demand response: Participation in utility programs that provide value for flexible charging.
Grid connection options:
Behind-the-meter service: Charging on existing building service (may require upgrades).
Dedicated service: Separate utility service for charging (may enable different rates).
Microgrids: Integration with on-site generation and storage.
Load management strategies:
Scheduled charging: Charging during off-peak hours when rates are lower.
Dynamic load management: Real-time allocation of available power across chargers.
Demand charge management: Strategies to reduce peak demand charges.
Phase 5: Financing and Incentives
Multiple funding approaches exist:
Incentive programs:
Federal programs: NEVI (National Electric Vehicle Infrastructure), IRS tax credits.
State programs: State-specific incentive programs varying by location.
Utility programs: Utility incentives for charging infrastructure.
Local programs: Municipal incentives in some areas.
Financing models:
Capital purchase: Own equipment and infrastructure outright.
Charging-as-a-service (CaaS): Third party owns and operates charging infrastructure.
Lease: Finance equipment over time.
Revenue sharing: Third party installs infrastructure in exchange for revenue share.
Business case development:
Fleet electrification: Compare total cost of ownership versus conventional vehicles.
Amenity charging: Value as amenity rather than profit center (talent attraction, customer experience).
Revenue charging: Pricing strategy, utilization assumptions, and revenue projections.
Phase 6: Implementation and Operations
Execution determines whether planning delivers value:
Implementation approach:
Phased deployment: Start with manageable scope; expand based on experience.
Contractor selection: Electrical contractors with EV charging experience.
Utility coordination: Allow adequate time for utility approvals and work.
Commissioning: Thorough testing before operational deployment.
Operational considerations:
Monitoring: Continuous visibility into charger status and utilization.
Maintenance: Regular maintenance schedule and responsive repair.
User support: Help desk and on-site support for charging issues.
Reporting: Utilization, energy consumption, and cost reporting.
Evolution and expansion:
Utilization monitoring: Track usage against projections.
Expansion triggers: Criteria for adding chargers or upgrading infrastructure.
Technology updates: Plan for equipment refresh cycles.
Special Considerations
Fleet Depot Charging
Fleet depot operations have unique requirements:
Scheduling and assignment: Matching vehicles to chargers based on routes and charging needs.
Power management: Managing depot load to avoid expensive demand charges.
Cold weather: Battery conditioning and charging efficiency in cold conditions.
Integration: Connection to fleet management systems.
Multi-Tenant and Mixed-Use
Properties with multiple tenants face complexity:
Cost allocation: How to charge back electricity costs to appropriate tenants.
Access control: Managing who can use which chargers.
Common area charging: Governance for shared charging resources.
Public Charging Business Models
Public charging is business operation:
Pricing strategy: Competitive pricing that covers costs and achieves utilization targets.
Payment processing: Multiple payment methods and reliable transaction processing.
Site selection: Locations with sufficient traffic and dwell time.
Key Takeaways
-
Plan for the future, build in phases: Infrastructure is expensive to replace. Plan capacity for future demand while deploying chargers incrementally.
-
Engage utilities early: Utility capacity and upgrade timelines often drive project schedules. Early coordination prevents surprises.
-
Match technology to use case: Right-size charging speed to actual needs. Over-specification wastes money; under-specification creates operational problems.
-
Consider total cost of ownership: Incentives, electricity costs, maintenance, and operations all affect economics. Cheap equipment isn't necessarily lowest cost.
-
Operational excellence matters: Chargers that don't work damage adoption and waste investment. Prioritize reliability and support.
Frequently Asked Questions
How many chargers do we need? Depends on vehicles served, parking patterns, and charging speed. A rough guide: one Level 2 charger per 3-4 fleet vehicles doing overnight charging, or higher ratios with load management.
Should we install the fastest chargers available? Not necessarily. Faster charging costs more. Match charging speed to dwell time. Overnight depot charging doesn't need DCFC; quick-turn retail destinations might.
Who should own and operate charging infrastructure? Options range from full ownership to turnkey charging-as-a-service. Consider internal capabilities, capital availability, and strategic importance.
What about future battery technology reducing charging needs? Battery advances are uncertain. Current infrastructure planning should address near-term needs while allowing for adaptation. Overbuilding for uncertain futures is expensive.
How do we handle demand charges? Strategic options include: load management systems, on-site storage, utility rate negotiation, charging scheduling, and dedicated service with different rate structures.
What happens when chargers become obsolete? Plan for technology evolution. Underground infrastructure (conduit, electrical capacity) lasts longer than chargers. Design for charger replacement without re-excavation.
