Tenant charging is EV charging provided for tenants in a shared property—such as apartment buildings, office parks, mixed-use developments, or industrial estates—where multiple independent users need access to charging and the costs must be allocated fairly. Tenant charging typically includes both the physical charging infrastructure and the operational model (access control, billing, support, and expansion rules).
Tenant charging is a core use case within multi-tenant charging and often requires strong coordination between the property owner, property manager, installer, and charging operator.
Why Tenant Charging Matters
Tenant charging is increasingly expected in modern properties and can influence leasing and retention. It matters because it:
– Helps properties stay competitive as EV adoption grows
– Supports tenant satisfaction and reduces churn (residential and commercial)
– Adds predictable infrastructure value to the building
– Requires fair billing and governance to avoid disputes
– Must be scalable: demand grows over time and needs phased expansion
Unlike single-user private charging, tenant charging must work reliably for many users with different schedules and vehicle types.
Common Tenant Charging Models
Tenant charging is typically delivered through one of these models:
– Dedicated tenant chargers
Each tenant has an assigned charger or bay (common in premium residential or fixed-parking offices)
– Shared chargers with access control
Multiple tenants share a pool of chargers managed via RFID/app user groups
– Hybrid model
A shared pool for visitors and general use plus dedicated bays for some tenants
– Managed service model
A CPO or charging service provider owns/operates the system and bills tenants directly
Billing and Cost Allocation
Tenant charging usually requires clear tenant billing policies, often using:
– Per-kWh billing for transparent cost allocation
– Optional service fees to cover platform, maintenance, and support
– Subscription charging plans for residents/employees in some properties
– Sub-metering or charger-level metering to allocate consumption accurately
– MID metering where billing regulations require certified measurement (market-dependent)
Electrical Architecture and Scalability
Tenant charging should be designed for expansion from day one:
– Use sub-distribution boards (SDBs) with spare breaker ways
– Install spare duct capacity and clear conduit routing for future bays
– Apply load management to stay within building and grid limits
– Use phased rollout: prepare infrastructure now, add chargers as adoption grows
This approach reduces repeat civil works and avoids expensive rewiring later.
Operational Requirements
Successful tenant charging programs typically include:
– Simple onboarding/offboarding (tenant move-in/move-out)
– Access control and user-group management
– Clear rules for bay usage, time limits, and optional idle fee policies
– Reliable uptime and responsive maintenance (low MTTR)
– Reporting for tenants and property managers (usage, costs, site performance)
Challenges and Risks
– Disputes if billing is unclear or metering is not trusted
– Peak demand spikes when many tenants charge simultaneously
– Insufficient future-proofing (no spare capacity, forcing expensive retrofits)
– Poor parking governance leading to ICEing or bay conflicts
– Connectivity issues in underground garages affecting backend control and reporting
Best Practices for Tenant Charging
– Start with an EV-ready infrastructure plan, not just “install a few chargers”
– Use load management and set a maximum site demand limit early
– Make billing transparent with itemized session records
– Separate tenant, visitor, and staff user groups for clean governance
– Document responsibilities (property manager vs operator vs installer) and service SLAs
– Keep expansion simple: spare ducts, spare board capacity, modular deployment
