Electric vehicle adoption is no longer a future scenario that parking operators can defer thinking about. In the United States, EV sales crossed 9 percent of new vehicle sales in 2023 and are projected to reach 25 to 35 percent by 2030, depending on which forecast model you consult. The EVs being sold today will be parking in your facilities for the next 12 to 15 years.
For parking operators, the EV transition creates both obligation and opportunity. The obligation: tenants, customers, and municipal regulations increasingly require EV charging access. The opportunity: parking facilities are among the most logical locations for charging infrastructure, and operators who position themselves well can capture a growing revenue stream while differentiating their facilities in competitive markets.
But EV charging infrastructure planning is more complex than installing a few chargers and posting a sign. Electrical capacity constraints, charging level decisions, payment integration, demand management, and long-term technology evolution all require thoughtful planning. The decisions you make today will shape your facility’s EV charging capability for the next decade.
Understanding Charging Demand
The first planning question is how much EV charging your facility needs, both today and over the next five to ten years.
Current Demand
Start with data. If your facility already has EV chargers, your utilization data tells you whether current supply is adequate. Utilization above 70 percent during peak hours suggests that you are turning away EV drivers or forcing them to wait. Utilization below 30 percent during peak hours suggests that you have overbuilt relative to current demand.
If you do not have chargers, estimate current demand from your vehicle mix. Conduct a one-week survey of the vehicles in your facility — count EVs and plug-in hybrids. In urban markets, EV penetration in parking facilities typically runs 3 to 8 percent of the vehicle population in 2024. In EV-heavy markets (California, Pacific Northwest, Northeast corridor), it can exceed 12 percent.
Future Demand Projections
Project forward based on new vehicle sales penetration. If 25 percent of new vehicles sold in 2030 are EVs, and the average vehicle age in a parking facility is 6 to 8 years, you can expect EV representation in your facility to reach 15 to 25 percent by 2035.
This is not a precise science, but the direction is unambiguous. Plan for EV charging capacity that grows with adoption. A common planning approach is to install chargers for current demand, pre-wire (install conduit and electrical panels) for 3 to 5 times current capacity, and reserve physical space for eventual build-out to 10 times current capacity.
Dwell Time Matters
Not every parking scenario generates the same charging demand. Dwell time — how long vehicles stay in your facility — determines which charging level is appropriate and how many chargers you need.
Long dwell time facilities (office buildings, residential, airports): EV drivers park for 8 or more hours and can charge slowly. Level 2 charging (240V, 7 to 19 kW) is ideal — it fully charges most EVs in 4 to 8 hours and requires less electrical infrastructure than faster alternatives.
Short dwell time facilities (retail, medical, entertainment): EV drivers park for 1 to 3 hours. Level 2 charging provides a meaningful but partial charge. DC fast charging (50 to 150 kW) provides a near-full charge in 30 to 60 minutes but requires substantially more electrical infrastructure and capital investment.
Mixed dwell time facilities (hospitals, universities, mixed-use): a combination of Level 2 and DC fast charging serves both long-stay and short-stay users.
Electrical Infrastructure: The Hidden Constraint
The most common bottleneck in EV charging deployment is electrical capacity, not physical space. A Level 2 charger draws 7 to 19 kW. A DC fast charger draws 50 to 150 kW. Ten Level 2 chargers at 10 kW each add 100 kW to your facility’s electrical load — equivalent to the total connected load of several residential homes.
Assessing Available Capacity
Engage a licensed electrical engineer to assess your facility’s current electrical capacity and available margin. Key questions: what is the building’s total electrical service capacity, what is the current peak demand, and how much spare capacity exists?
In many existing parking structures, the spare electrical capacity is limited — often enough for 5 to 15 Level 2 chargers without an electrical service upgrade. Beyond that, you may need transformer upgrades, new utility service connections, or both.
Managing Electrical Costs
Electrical costs for EV charging have two components: energy charges (per kWh consumed) and demand charges (based on peak kW draw). In many commercial rate structures, demand charges represent 30 to 50 percent of the total electric bill for EV charging loads.
Smart charging management — also known as load management or demand response — reduces peak demand by distributing charging across available time windows rather than allowing all chargers to operate at maximum power simultaneously. If ten EVs are plugged in at an office building at 8 AM but do not leave until 5 PM, there is no reason to charge all ten at full power simultaneously. Staggering the charging across the nine-hour window dramatically reduces peak demand while still delivering full charges.
Load management software is essential for any deployment larger than a few chargers. The software monitors available electrical capacity, distributes power across active charging sessions, and may integrate with the utility’s demand response programs for additional revenue.
Pre-Wiring for Future Capacity
The most expensive part of EV charging infrastructure is the electrical distribution — conduit runs, panel boards, and wiring. Installing this infrastructure during new construction or major renovation is a fraction of the cost of retrofitting later.
Industry best practice is to pre-wire for at least three times your initial charger count. This means installing conduit, pulling wire, and provisioning panel capacity for future chargers even if you only install a few initially. The incremental cost of pre-wiring during construction is 10 to 20 percent of the retrofit cost.
Revenue Models
EV charging in parking creates revenue opportunities, but the revenue model you choose affects customer experience, operational complexity, and financial performance.
Free Charging as Amenity
Some facilities offer free EV charging as a tenant amenity or customer attraction. This model is simple to implement — no payment infrastructure required — but creates problems at scale. Free charging attracts non-customer usage, creates hoarding behavior (EVs staying plugged in after charging is complete), and becomes increasingly expensive as EV adoption grows.
Free charging works as a short-term differentiator for facilities with low EV penetration and a desire to attract EV-driving customers. It is not sustainable as a long-term model.
Fee-Based Charging
Fee-based charging generates revenue and creates economic incentives that discourage hoarding and non-customer use. Pricing structures include per-kWh (charges based on energy delivered), per-hour (charges based on time connected), and hybrid models (per-kWh during active charging, per-hour idle fees after charging completes).
Per-kWh pricing is the most fair to drivers and the most transparent, but is regulated as an electricity sale in some jurisdictions, requiring the operator to register as an electric utility. Per-hour pricing avoids this regulatory complexity but may charge drivers differently for the same amount of energy depending on their vehicle’s charge rate.
The integration of EV charging payment with parking payment is an emerging trend. Smart parking systems that combine parking and charging into a single transaction — one payment for parking time plus charging energy — simplify the customer experience and create cross-selling opportunities (discounted parking when charging, or vice versa).
Third-Party Charging Networks
Operators can partner with charging network providers (ChargePoint, Blink, EVgo, and others) who install and operate the chargers in exchange for revenue sharing or space lease payments. This model minimizes the operator’s capital investment and operational burden but also minimizes the operator’s revenue and control.
The partnership terms vary significantly between providers. Some networks cover hardware, installation, and maintenance in exchange for all or most of the charging revenue. Others sell or lease hardware to the operator, who retains the charging revenue but bears the operational costs.
Evaluate partnerships carefully. The terms that seem attractive when EV penetration is 5 percent may be unfavorable when penetration reaches 20 percent and charging revenue becomes a material line item.
Planning Mistakes to Avoid
Installing chargers without understanding electrical capacity. Operators who install chargers first and assess electrical capacity second often discover that they cannot expand without expensive electrical upgrades.
Placing chargers in the wrong locations. EV charging spaces should be located where they are visible, accessible, and do not block traffic when vehicles connect or disconnect. Placing chargers in the back corner of the garage to avoid construction complexity results in underutilization and customer frustration.
Ignoring maintenance requirements. EV chargers require maintenance — cable management, connector cleaning, software updates, and occasional hardware replacement. Level 2 chargers are relatively low-maintenance, but DC fast chargers have complex power electronics that require specialized service. Budget for maintenance from day one.
Failing to plan for technology evolution. Charging standards and capabilities are evolving rapidly. Tesla’s NACS connector has become the North American standard, displacing the CCS connector for many new installations. Bidirectional charging (vehicle-to-grid) is emerging. Choose equipment and infrastructure that can accommodate these changes without a full rebuild.
Underestimating the time to install. EV charger installation in existing facilities typically takes 3 to 6 months from planning to energization, driven primarily by electrical engineering, permitting, and utility coordination. Large installations with electrical service upgrades can take 9 to 12 months. Start planning well before you need the chargers operational.
The Strategic View
EV charging infrastructure is one of the largest capital investments that parking operators will make in the coming decade. It is also one of the most strategically important.
Facilities with robust EV charging infrastructure will be more attractive to tenants, customers, and visitors as EV adoption grows. Facilities without it will be at a competitive disadvantage that widens over time. The cost of deploying charging infrastructure increases the longer you wait — pre-wiring during planned renovations is far cheaper than retrofitting later.
The operators who approach EV charging strategically — assessing demand, planning electrical infrastructure, choosing sustainable revenue models, and building for growth — will capture value from the electric transition. Those who treat it as an afterthought will face reactive, expensive catch-up that costs more and delivers less.
The electric transition in parking is not a question of if, but when. The time to plan is now.
