Define the charging station profile

Before comparing locations, define the audience you want to serve: traveling drivers, urban users, customers of commercial establishments or vehicle fleets.

This choice guides the analysis. Highway charging depends on access and convenience during a journey. An urban facility may serve users who stay longer at the location. For fleets, charging schedules and concentration matter more.

ePowerBay lets you start studies directly on the map, compare locations and reopen saved analyses. This workflow was introduced with the launch of the e-mobility location tools.

1. Select locations on the map

Open the Map, find your area of interest and right-click a candidate location. Select the Electric Mobility analysis type.

Give the point a name that makes comparison easy, such as “Highway — north access” or “Shopping center — south area”, and adjust the analysis radius.

Add other candidates and use the same radius when comparing similar locations. This avoids comparing indicators calculated over very different areas.

2. Examine potential demand and charging supply

Check indicators for electric vehicles in the municipality, nearby DC charging stations, population and distances to federal and state highways.

Use this information to investigate the market:

• Municipal vehicle fleet: helps assess the presence of electric vehicles in the city.

• Nearby DC charging stations: shows the recorded supply of fast charging nearby.

• Highways: helps identify sites near travel corridors.

• Population: provides municipal context.

The municipal fleet does not represent the number of vehicles passing the selected address. Similarly, few charging stations may indicate an opportunity or still-limited demand.

The nearby charging station count considers publicly accessible fast-charging records within the search radius. Complement the assessment on the map to understand their distribution.

3. Compare candidates side by side

Add different points to the comparative analysis and examine the table, radar chart and final index.

Compare each indicator individually. One location may have a larger municipal fleet, while another has fewer nearby fast-charging stations or is closer to a highway.

The final index organizes a preliminary comparison according to the tool's criteria. It is not a forecast of revenue, charger utilization or investment returns.

Use the comparison to select locations for detailed investigation.

4. Investigate distribution infrastructure

On the map, find and activate Distribution Grid Substations, Medium-Voltage Networks, Low-Voltage Networks and Transformers, subject to available coverage.

Examine infrastructure near the address and open the details of relevant features.

Then access E-Mobility Location Analysis Results. This screen provides nearby substations and nearby transformers, including distances and available network associations.

For further investigation, use Distribution Grid Substations. Search using Location, Distribution Utility, State and Municipality, and open the relevant substation.

Review available transformers, feeders and load data. Network proximity, a transformer's rated capacity and connected load do not establish spare capacity to supply chargers.

Confirmation requires the distribution utility's assessment of the address and requested capacity.

5. Examine tariffs and the operating profile

On the analysis results page, consult Tariffs, including Conventional B3 and A4 references for the identified distribution utility.

Check TE and TUSD components, units, tariff modalities and time periods shown.

To assess charging station costs, also consider charger power, simultaneous charging, operating hours and contracted demand where applicable. Comparing only energy prices may omit relevant operating costs.

Review available service continuity indicators, such as DGC, DEC and FEC, to contextualize supply quality. These indicators do not guarantee performance at a specific address.

6. Complement the assessment for your business model

Other solutions can support specific expansion stages:

• Medium-Voltage Consumer Units: explore nearby consumers when considering commercial partnerships or serving establishments. Use the available location, distribution utility and consumption filters.

• Distributed Generation Plants: investigate existing installations nearby to understand the local generation context.

• DG Location Analysis: develop a complementary study when the project also involves distributed generation.

• CCEE Agents: consult available agent information when planning involves energy procurement in Brazil's free electricity market.

Nearby generation does not establish energy availability for the charging station. Each alternative requires its own technical and commercial assessment.

7. Save, export and organize the next step

Save analyses with clear names and use Load saved analyses to reopen them on the map. E-Mobility Location Analysis centralizes studies and lets you open each point's details.

Use Export spreadsheet to include the comparison in your expansion studies. Record the radius, query date and issues still requiring confirmation.

For selected sites, proceed to check property access, vehicle circulation, parking, commercial terms and electricity supply.

The platform helps organize selection and focus investigation on the most relevant candidates. Installation decisions should combine researched data with assessment of the address and actual operating conditions.
