Why EV Charging Station Site Selection Matters

Choosing the right location is one of the most important decisions in developing an electric vehicle (EV) charging station. A site with high traffic does not automatically guarantee strong charging demand, and a location with low rent may still become an expensive investment if grid upgrades, construction, or operating costs exceed expectations.

For charging point operators (CPOs), investors, fuel station owners, and commercial property developers, successful site selection requires more than identifying an accessible parking lot. It requires a structured assessment of market demand, electrical infrastructure, competitive positioning, regulatory requirements, and long-term financial performance.

According to the International Energy Agency (IEA), the number of public charging points worldwide exceeded 7 million by the end of 2025, following growth of more than 33% during the year. The global average reached approximately 11 electric light-duty vehicles per public charging point, with around 4.5 kW of public charging capacity available per electric light-duty vehicle.

These global averages illustrate the scale and pace of infrastructure deployment. However, they should not be used as universal site-level investment benchmarks. Charging demand, vehicle ownership, charging behavior, power availability, and competitive conditions differ significantly between countries and locations.

1. Mistake #1: Choosing a Location Based on Traffic Volume Alone

High traffic does not necessarily mean high charging demand.

A busy highway, shopping district, or fuel station may appear attractive, but traffic volume alone does not reveal how many vehicles need to charge, how long drivers will stay, or whether they will choose the proposed station.

A more useful demand assessment considers local EV population and adoption trends; daily vehicle movements and traffic direction; the proportion of drivers who may need public charging; nearby residential communities, offices, commercial centers, and logistics facilities; existing charging behavior and unmet demand; and expected demand growth over the investment horizon.

How to avoid this mistake: Conduct a local market study before selecting equipment or negotiating a long-term lease. For urban sites, examine the surrounding EV population, parking patterns, residential density, and access to private charging. For highway locations, investigate traffic in both directions, available exits, detour distances, rest-stop behavior, and seasonal demand. For fleet-oriented locations, obtain actual vehicle counts, daily mileage, operating schedules, and charging requirements wherever possible.

Professional recommendation: Use observed charging activity, fleet commitments, and defensible demand estimates rather than relying solely on total traffic counts or broad EV adoption forecasts.

2. Mistake #2: Ignoring Grid Capacity and Electrical Connection Costs

Grid connection can determine whether a seemingly attractive location is financially viable. A site may have sufficient parking space but insufficient electrical capacity to support multiple DC fast chargers. Upgrading the supply may require a new transformer, switchgear, utility service, underground cabling, civil works, or other infrastructure.

Before committing to a site, investigate: existing transformer rating and available spare capacity; maximum demand from the host facility; available supply voltage and connection requirements; distance from the point of connection to the charging equipment; required utility upgrades and estimated connection fees; permitting, construction, and commissioning timelines; and opportunities for load management or staged expansion.

Example: A proposed station with four 120 kW DC chargers has a combined rated output of 480 kW. This does not mean the station will continuously draw 480 kW, but the electrical design must account for the maximum simultaneous demand permitted by the charger configuration and site power-management strategy, together with other site loads and applicable design requirements.

If the existing supply cannot accommodate the proposed installation, the operator must compare the cost of grid upgrades with alternatives such as dynamic power sharing, a phased rollout, or a properly engineered battery energy storage system. The decision should be based on a formal electrical assessment, not an assumption that sufficient power is available.

3. Mistake #3: Installing Too Much Charging Power Too Early

Higher charging power can improve service for drivers who need rapid charging, but it does not automatically produce higher profits. The appropriate power rating depends on vehicle charging capability, expected session duration, site turnover, grid constraints, and the operator's commercial model.

Highway service areas may benefit from higher-power DC charging; urban public charging sites may need a mix of power ratings; commercial fleets may benefit from managed charging based on departure schedules; and hotels and workplaces may be better suited to AC charging where vehicles remain parked for several hours.

The IEA distinguishes public charging points rated at 22 kW or below as slow chargers, those above 22 kW and up to 150 kW as fast chargers, and those rated at 150 kW or above as ultra-fast chargers in its light-duty vehicle charging analysis.

How to avoid oversizing: Estimate hourly charging demand, peak simultaneous load, expected energy sales, and vehicle dwell time. Compare alternative configurations against the same demand forecast. Where appropriate, consider modular expansion, dynamic power allocation, and electrical infrastructure designed to accommodate future chargers without unnecessary initial equipment purchases.

4. Mistake #4: Evaluating Competitors by Counting Chargers Only

A large number of nearby charging stations does not necessarily mean the market is saturated. Existing stations may experience long queues, poor uptime, inconvenient access, incompatible connectors, limited payment options, or pricing that leaves room for a better-positioned competitor. Conversely, few nearby chargers may indicate limited demand rather than an attractive opportunity.

Evaluate competing stations using charging session volume, energy sold per day, charger uptime, peak-hour queues, charging price, connector compatibility, accessibility, and customer feedback.

Where reliable public data are available, use them to compare competitors. Otherwise, conduct site visits at different times, consult local fleet operators, and gather evidence from charging applications and station operators.

Important: A competitor's existence is not proof of market demand. The strongest investment case combines evidence of demand with a specific, defensible reason customers would choose the new site.

5. Mistake #5: Underestimating Electricity Tariffs and Demand Charges

Charging station profitability depends on the cost of delivering electricity, not just the retail price charged to drivers. Depending on the market and utility tariff, electricity expenses may include energy consumption charges per kWh, time-of-use pricing, demand charges based on measured peak power, fixed service charges, connection or network charges, taxes, and other applicable fees.

Demand charges are particularly important for DC fast-charging stations. A station may sell relatively little energy during a month but still incur substantial costs if it creates a high peak demand.

Illustrative financial example: Assume a charging station sells 2,304 kWh per day, the average retail charging price is $0.40/kWh, and variable electricity cost is $0.25/kWh. The contribution margin before other costs is $0.15/kWh. Daily contribution before fixed costs is 2,304 × ($0.40 − $0.25) = $345.60. Annual contribution before fixed costs is $345.60 × 365 = $126,144.

These figures are hypothetical and are not a forecast for any particular market. The resulting amount is not net profit. It excludes demand charges, rent, depreciation, financing, network fees, maintenance, labor, insurance, taxes, and other operating expenses.

Before selecting a site, request the applicable utility tariff and model the total electricity bill under realistic charging-load scenarios.

6. Mistake #6: Overlooking Access, Parking Layout, and Driver Experience

A charging station should be easy to find, enter, use, and exit. A location may have sufficient traffic and electrical capacity but still underperform because drivers must make difficult turns, cross congested intersections, navigate unclear entrances, or compete for parking with other users.

Site planning should address safe vehicle entry and exit; visibility from the road and accurate navigation information; adequate turning space and charging-bay dimensions; queueing without blocking traffic; cable reach and charger placement; accessibility requirements; lighting, signage, personal security, and weather protection where appropriate; and amenities suited to the expected charging duration.

The appropriate layout also depends on vehicle type. Passenger cars, delivery vans, buses, and heavy-duty trucks have different space and maneuvering requirements.

Practical recommendation: Test the actual driving route to the proposed site and review the layout with an experienced electrical and civil engineering team before finalizing the design.

7. Mistake #7: Signing a Lease Before Confirming Permits and Site Rights

A long-term lease does not guarantee that a charging station can be built or operated. Potential restrictions include land-use zoning, building permits, electrical approvals, fire and safety requirements, utility easements, access rights, parking restrictions, and limitations imposed by the property owner.

Before signing a binding agreement, verify that the site can legally accommodate the proposed charging activity; the operator has the right to install, operate, maintain, and replace equipment; utility connections and cable routes are legally permitted; construction and operating approvals are obtainable; the lease term is compatible with investment and payback; the contract addresses rent increases, renewal, termination, equipment ownership, and removal obligations; and expansion rights are sufficient.

Requirements differ by jurisdiction. Local regulatory and legal review should form part of site due diligence, rather than being postponed until after equipment procurement.

8. Mistake #8: Failing to Account for Reliability and Maintenance

A charging port that is installed but unavailable cannot generate normal charging revenue. Reliability affects customer trust, repeat usage, station visibility on charging networks, and the operator's ability to meet contractual or regulatory requirements.

For projects funded under the U.S. National Electric Vehicle Infrastructure (NEVI) Formula Program, applicable federal standards require charging ports to maintain average annual uptime of greater than 97%, subject to the regulation's calculation methodology and exclusions. This is a program-specific requirement, not a universal legal standard for every charging station worldwide.

During site evaluation, assess the availability of qualified local maintenance technicians, replacement parts and technical support, remote monitoring and fault diagnostics, network connectivity and payment systems, preventive maintenance services, and clear service-level agreements and escalation procedures.

A well-selected site should support not only installation, but also reliable operation throughout the equipment's service life.

9. Mistake #9: Ignoring Solar, Storage, and Intelligent Energy Management

For sites with suitable solar exposure, electricity tariffs, load profiles, and available space, integrating photovoltaic generation and battery energy storage may improve energy management. Potential applications include increasing on-site use of solar electricity, reducing grid imports during selected peak periods, managing simultaneous charging demand, supporting staged charging capacity expansion, and improving energy flexibility where local tariffs make it economical.

However, solar and storage should not be treated as automatic cost-saving measures. The investment case depends on local electricity prices, demand charges, solar generation profiles, storage efficiency, battery degradation, equipment costs, interconnection rules, and hourly charging demand.

Compare at least two scenarios: (A) grid-connected EV charging without on-site storage; and (B) grid-connected charging with appropriately sized solar generation, battery storage, and an energy management system where justified. Compare total capital expenditure, annual energy costs, peak demand, maintenance, replacement costs, and cash flow over the same evaluation period.

The preferred configuration is the one that delivers the strongest risk-adjusted economic result under realistic operating assumptions.

10. Mistake #10: Approving a Project Without a Financial Feasibility Model

A location should not be approved simply because it meets technical requirements. The investment must also make commercial sense.

Capital expenditure (CAPEX) may include chargers and power modules, transformers, switchgear and cabling, civil works and parking modifications, utility connection and capacity upgrades, software integration, payment systems and commissioning, and solar and storage equipment if applicable.

Operating expenditure (OPEX) may include electricity and demand charges, rent and property-related fees, network and payment-processing fees, maintenance and spare parts, labor, insurance, taxes, and financing costs.

Revenue assumptions should include daily charging sessions, average energy delivered per session, expected kWh sold per day, charging prices and applicable fees, and ancillary revenue supported by a credible business case.

A useful starting metric is contribution margin per kWh: charging revenue per kWh minus variable cost per kWh. Approximate annual break-even energy sales can be estimated as annual fixed operating costs divided by contribution margin per kWh. This simplified calculation assumes a positive contribution margin and excludes capital recovery.

A complete investment evaluation should include net present value (NPV), internal rate of return (IRR), payback period, and downside scenarios. Test lower-than-forecast energy sales, increased electricity prices, construction cost overruns, and commissioning delays.

Investment rule: If a project only becomes profitable under an optimistic utilization forecast, reconsider the location, lease terms, infrastructure design, or deployment scale.

Final Thoughts: Choose a Site That Can Support Long-Term Operations

Successful EV charging infrastructure begins with a disciplined site selection process. The most attractive location is not necessarily the one with the highest traffic, lowest rent, or largest available parking area. It is the location where verified charging demand, accessible electrical capacity, reasonable installation costs, competitive positioning, regulatory feasibility, and sustainable operating economics come together.

For charging station operators, the recommended sequence is straightforward:

1. Validate demand before committing to a site.

2. Confirm grid capacity and connection costs before finalizing the design.

3. Match charging power to actual vehicle and operating requirements.

4. Model the complete cost of ownership and test downside scenarios.

5. Secure the necessary site rights and approvals.

6. Deploy in phases and expand based on measured utilization.

A structured approach reduces the risk of stranded assets, unnecessary grid upgrades, oversized installations, and disappointing utilization.
