Load Profiles in Eturnity Expert

Select, edit, and import consumption data as load profiles for accurate PV system simulations and precise self-consumption calculations.

Understanding Load Profiles

Load profiles in Eturnity Expert represent electricity consumption patterns that are crucial for accurate PV system simulation and self-consumption calculations. These profiles show how much electricity a building consumes, enabling you to design optimally sized PV systems and provide precise feasibility assessments to your customers.

Why load profiles matter:

  • Accurate system sizing: Match PV system capacity to actual consumption patterns

  • Precise self-consumption simulation: Calculate realistic energy savings and payback periods

  • Better customer consultation: Show customers exactly how their system will perform

  • Improved project feasibility: Make data-driven decisions about system viability

Types of Load Profiles

Eturnity Expert provides three main categories of load profiles, each designed for different building types and use cases:

Residential Profiles

Standard consumption patterns for residential buildings, including:

  • Single-family houses with different heating systems (heat pump, electric, oil/gas)

  • Profiles optimized for different household sizes and lifestyles

Commercial & Industrial Profiles

Specialized profiles for business and industrial applications, organized by sector:

  • Hospitality: Hotels, restaurants, and service businesses

  • Construction: Manufacturing and construction companies

  • Manufacturing: Industrial production facilities

  • Office buildings: Corporate and administrative facilities

License Note: Commercial & Industrial load profiles require a full license and commercial load profiles add-on. If you don't see these options, please contact support@eturnity.com to learn about upgrade options.

Individual Profiles

Custom profiles that you can create and manage by downloading a CSV template and importing real consumption data:

  1. Download the CSV template from the Individual Profiles section

  2. Fill in the template with your customer's real consumption data:

    • Column A: Seconds in 15-minute intervals throughout the year

    • Column B: Corresponding consumption values

  3. Ensure the template matches exactly - no rows or columns should be deleted or added

  4. Upload the completed CSV file to create your custom profile

Important: The CSV template must be used exactly as provided. Do not modify the structure, add or remove rows/columns, or change the format. The template ensures compatibility with Eturnity's load profile system.

Selecting a Load Profile

To select an appropriate load profile for your project:

  1. Navigate to Project View > Electricity Usage

  2. Use the profile type tabs to switch between Residential, Commercial & Industrial, and Individual Profiles

  3. Browse the available profiles or use the search functionality to find specific profiles

  4. Click on a profile to select it - the system will immediately show a visualization of the monthly consumption pattern

  5. Review the profile details including annual consumption, building type, and heating system

Profile selection tips:

  • Match the building type (single-family, office, industrial)

  • Consider the heating system (heat pump, electric, oil/gas)

  • Account for occupancy patterns (residential vs. commercial hours)

  • Use search functionality to quickly find relevant profiles

Editing Load Profiles

You can customize any selected profile to better match your customer's specific consumption patterns:

  1. After selecting a profile, click Edit Profile

  2. Choose your editing mode:

    • Monthly editing: Adjust consumption for each month of the year

    • Sub-daily editing: Modify consumption patterns within each day

  3. Make your adjustments using the interactive charts and input fields

  4. Click Save Load Profile to apply changes

Regional Editing Options

Depending on your market, additional editing options are available:

🇮🇹 Italy: Fasce-based editing allows you to adjust consumption according to Italian tariff zones (F1, F2, F3).

🇪🇸 Spain: P1-P3 tariff zone editing enables consumption adjustments based on Spanish electricity tariff periods.

🇫🇷 France: Daytime-based splitting allows detailed control over consumption patterns throughout the day.

E-Mobility Load Addition

You can extend your selected load profile with electric vehicle charging by adding E-Mobility consumption:

  1. Select your base load profile (residential, commercial, or individual)

  2. Click on "Edit EV" to extend the profile

  3. Configure the electric vehicle parameters:

    • Specific energy consumption: Energy consumption per kilometer (kWh/km)

    • Daily driving distance: Average daily kilometers driven

    • Charging power: Vehicle charging capacity (kW)

  4. Set the charging schedule:

    • Define when the vehicle is typically charged (time periods)

    • Specify charging duration and frequency

    • Adjust for seasonal variations if needed

  5. Save the enhanced profile with E-Mobility consumption

License Note: The E-Mobility feature is only available with the E-Mobility Add-on. If this feature is not included in your license and you are interested, please contact support@eturnity.com.

Annual Consumption Adjustment

You can adjust the annual consumption value to match your customer's specific needs:

  1. In the Electricity Usage section, locate the Yearly consumption field

  2. Enter the customer's actual annual consumption in kWh

  3. The system will automatically scale the selected profile to match this consumption

  4. Review the updated monthly distribution in the visualization

Important: This scaling maintains the relative consumption patterns while adjusting the absolute values to match your customer's actual usage.
