Commercial EV Site Planning Tool

Tesla V4 Supercharger
Site Pro Forma

Estimate your site's profitability with real Georgia Power tariff data, Tesla Model Y charging curve modeling, and invoice-calibrated utility fees. Built for business owners considering their first EV charging investment.

Duke Service Territory
Which Duke utility serves your site?
Duke operates separate utilities with different rate schedules. Your site's physical location determines which one applies and which rate you'll ultimately be placed on. Duke Energy Carolinas (DEC) covers Charlotte, Greensboro, Durham, Asheville. Duke Energy Progress (DEP) covers Raleigh, Wilmington, Fayetteville. DEC's demand charge is roughly half of DEP's — it matters a lot for fast-charging economics.

Site Information
Site Address
Where will the chargers be installed?
Enter the street address of the site you're considering. As you type, suggestions will appear to help you select the exact location. We use the address to estimate expected customer traffic and charging demand based on the property type and surrounding area.
Site Type
What kind of property is this?
Different property types attract different amounts of charging traffic. An airport-adjacent site sees rideshare drivers all day; a hotel sees mostly evening charging from overnight guests; a highway corridor sees road trippers in a hurry. We'll automatically detect this when you pick an address above, but you can override it manually if you know your site better than the map does.
Price You Charge Drivers
What will you charge EV drivers per kWh?
This is the price drivers see at the pump, so to speak. In Georgia, public fast charging typically ranges from $0.42 to $0.58/kWh. Tesla's own Superchargers average around $0.52/kWh. Lower prices attract more traffic but reduce margin per session. Higher prices mean better margin but you may see reduced utilization in competitive markets. Default of $0.52/kWh is the current Tesla Supercharger national average and a fair middle-ground starting point for ROI modeling.

Financial Assumptions
Projection Period
How many years to project revenue and costs?
Tesla V4 hardware has an expected useful life of 15+ years with proper maintenance. A longer projection shows more total revenue but also introduces more uncertainty about future market conditions, EV adoption, and equipment replacement. Default of 15 years matches standard infrastructure investment analysis and the typical warranty life of charging equipment.
Discount Rate
The "time value of money" rate.
A dollar earned ten years from now is worth less to you than a dollar earned today because you could invest today's dollar and grow it. The discount rate represents your required return: if you could safely earn 10% a year investing your money elsewhere, that's your benchmark. This tool uses your discount rate to convert future cash flows into today's dollars (Net Present Value, or NPV). Default of 10% is a standard benchmark for commercial infrastructure investments. Use 8% for conservative long-term capital, 12-15% if you have higher-return alternatives available.
Annual Utilization Growth
How fast will charging volume grow year over year?
EV adoption is still accelerating in the US. As more EVs hit the road, a busy charging site will see growing demand. This setting assumes your daily charging volume grows by this percentage each year. Default of 7% is a moderate assumption reflecting current EV market growth forecasts. Use 4-5% for a conservative case, 10%+ if you believe in aggressive adoption.
First Operating Year
The calendar year your site starts selling electricity.
Used to time year-specific costs — most importantly Georgia's motor-fuel excise tax on public EV charging (~$0.028/kWh), which takes effect January 1, 2027 under SB 146 / HB 516. Projection years falling in 2027 or later include it automatically on the Georgia Power side. Default of 2027 reflects a realistic install timeline for V4 equipment ordered now (equipment lead time + utility service work + permitting).
Driver Sales Tax Handling
Sales tax comes out of your charging revenue.
Electricity sold to drivers is a taxable retail sale of tangible personal property (in Georgia: O.C.G.A. § 48-8-30; SB 146 § 46-2-20.1(b) expressly calls it "a sale at retail"). Networks like Tesla post tax-inclusive prices and remit the sales tax out of the gross — so a $0.52 posted price at 7% tax nets you about $0.486/kWh. Florida and South Carolina treat charging revenue as taxable retail sales as well. Default withholds the sales tax rate from the active utility panel (Sales Tax %) from all revenue. Switch to gross only if you will collect tax on top of your posted price. Post-2027 Georgia treatment (motor-fuel exemption interplay) is modeled conservatively — sales tax stays applied alongside the excise.

Fuel Cost Recovery ($/kWh)
Georgia Power's fuel pass-through charge.
This is what Georgia Power charges to recover the cost of natural gas and coal burned to generate your electricity. It's adjusted quarterly and has ranged from $0.02 to $0.05/kWh over the past few years. Default of $0.045876/kWh matches the rate on real Georgia Power commercial invoices from August 2025.
Env. Compliance (%)
Environmental compliance cost recovery.
A percentage-based charge Georgia Power adds to cover costs of meeting state and federal environmental regulations (emissions controls, water treatment, coal ash management). Default of 13.23% reflects actual Georgia Power commercial invoices from August 2025.
Demand Side Mgmt (%)
Demand Side Management schedule.
A small line-item charge that funds Georgia Power's energy-efficiency rebate programs (the same programs that gave you the $30k EV business rebate, ironically). Default of 1.29% matches real commercial invoices. This is one of the smaller adders.
Municipal Franchise (%)
Your city's cut for letting the utility operate in their jurisdiction.
Cities charge the utility a franchise fee for using public rights-of-way, and the utility passes it through to you on your bill. Rates vary by city - Atlanta is around 4%, smaller cities may be 3% or less. Default of 3.5% is a reasonable Georgia middle-ground.
Sales Tax (%)
State + local sales tax on your electric bill.
Georgia state sales tax is 4%, plus county/city add-ons typically 3-4%. Total usually lands between 7-9% depending on jurisdiction. Default of 8% is typical for Metro Atlanta counties. Note: buying your electricity tax-free for resale (ST-5 certificate) is legally plausible but unconfirmed — no GA DOR ruling exists for charging operators. Do not present an ST-5 to Georgia Power without a DOR letter ruling; consult a Georgia SALT professional.
Excess Facilities ($/mo)
Monthly fee for dedicated utility equipment.
If Georgia Power installs dedicated equipment that serves only your site, they may charge an ongoing monthly fee. Per guidance from Georgia Power, this charge only applies when the cost of distribution equipment exceeds a revenue ratio calculation specific to your customer account. Most sites will not have this charge. Default of $0/month reflects the typical case. Only populate this field if Georgia Power has specifically told you your site will be assessed an Excess Facilities charge.
GA EV Excise Tax ($/kWh, 2027+)
Georgia's motor-fuel excise tax on public EV charging.
Under SB 146 (as delayed by HB 516), electricity sold at public charging stations is taxed like motor fuel starting January 1, 2027. The rate derives from Georgia's per-gallon gasoline excise with one gallon equivalent capped at 11 kWh — roughly $0.028/kWh today, adjusted annually. Applied automatically to projection years falling in 2027 or later (see First Operating Year). Default of $0.028/kWh ≈ current gasoline excise ÷ 11 kWh/GGE. Home and non-public charging are not taxed. This is separate from — and in addition to — sales tax.
Methodology validation: Rate structure, tier breakpoints, and adder percentages validated directly against Georgia Power's official Power and Light Calculator at georgiapower.com. Both PLM (Medium, 30-499 kW demand) and PLL (Large, 500+ kW demand) rate structures are implemented. Tariff selection is automatic based on actual peak demand (pre-BDAF). Results from this tool match the GA Power calculator to the penny across scenarios from 50 kW / 5,000 kWh up to 998 kW / 500,000 kWh.

Peak demand modeling: Tesla Model Y is used as the reference vehicle (peak ~250 kW brief, average ~150 kW sustained during the 30-minute billing demand window). Cabinet demand scales with how many cars charge simultaneously during peak hour, capped at 998 kW per cabinet (1,996 kW for 2-cabinet sites).
