Baseline Calculator

The Baseline Calculator feature of FactoryTalk Energy Manager aims to facilitate energy conservation efforts through accurate baseline calculation using regression analysis. This enables the users to establish baselines, forecast energy consumption, and assess the effectiveness of energy conservation measures.
Perform the following steps to carry out the baseline calculation for a model:
  1. From the left navigation panel, click the [] icon.
  2. Click
    Add Model
     or click the [+] icon.
    IMPORTANT:
    Users can create up to 10 models per site.
    Add Model
  3. Provide a unique name for the baseline model.
  4. Select the
    Baseline Start Date
     and
    Baseline End Date
     using the date picker.
    NOTE:
    Users select the start and end date of the baseline calculation period. The application does not allow the selected date range after Today (the present day). This date range decides how much data will be used for the baseline model training and formula creation. The meters selected in the previous step may have data from previous and future times than the selected date range, but the selection of the range narrows down the data to be used for calculations.
  5. Select the
    Granularity
     as
    Day/Month
     from the drop-down list.
    NOTE:
    The
    Granularity
     option decides the resolution of data within the selected date range.
    For example, if date range is 01-Jan-2025 to 31-March-2025.
    • When granularity=Day, 90 observations will be used during baseline calculation.
    • When granularity=Month, three observations will be used during baseline calculation.

  6. Click on the
    Dependent Variable
     field. The
    Dependent Variable Y Configuration
     dialog is displayed.
    NOTE:
    Click the [] icon to rename the Variable. Ensure that the variable name is unique.
    Dependent Variable Y Configuration
  7. Select a resource meter from the hierarchy for the dependent variable Y configuration and click
    Submit
    .
    TIP:
    The user can use the search option to navigate to the resource meter easily.
    NOTE:
    Users can select meters that are already present in the FactoryTalk Energy Manager energy model as
    Dependent Variable
     which will internally select the timeseries tagged to these meters.
    • Resource Meter
       under the same site as the selected model, can be selected as the
      Dependent Variable Y
      .
    Only the Resource meters are enabled to select, and all the other meters are disabled.
    Submit Variable
    NOTE:
    The application displays the message "
    Data unsuitable for Baseline Analysis: > 10% null datapoints in selected meter(s)
    " message for X variables when multiple X meters are selected and the combination of datapoints in these meters exceeds 10% null datapoints.
    Data Unsuitable for Baseline Analysis
  8. Once the variable is added, the Resource type is auto-filled.
    Dependent Variable Y
  9. Click on the
    Independent Variable(s) Xn
     field. The
    Independent Variable(s) Xₙ Configuration
     dialog is displayed.
    Independent Variable(s) Xₙ Configuration
  10. Select a Production/Process Value/Resource meter for the independent variable X configuration, select the Measurement Type from the dropdown, and click
    Submit
    .
    NOTE:
    Users can select meters that are already present in the FactoryTalk Energy Manager energy model as
    Independent Variables
     and
    Dependent Variable
     which will internally select the timeseries tagged to these meters.
    • Independent Variable(s) Xn
       is the
      Process value meter/Production meter
       under the same site.
    All the other meters are disabled.
    Independent Variable
    TIP:
    Use the [+] icon to add up to 5 variables and use the [] icon to rename or delete a variable.
  11. Click
    Calculate
    .
    Calculate Baseline Model
    The
    Correlation
     chart along with the
    Regression Statistics
     is displayed.
    Baseline Calculation
    NOTE:
    The equation for a straight line is y = mx + c or, in case of energy consumption driven by output: Energy = (Slope x Output) + Intercept
    In this equation, the intercept represents the energy consumption as output trends toward zero (the baseload) and the slope represents the incremental energy consumed per unit of output.
    A high baseload can indicate significant potential for energy savings by investigating on why so much energy is consumed even when production trends towards zero.
  12. Click
    Save
    . The "
    Model saved successfully
    " message is displayed, and the model is added to the list.
    The last updated time stamp is displayed at the bottom.

Edit Model

The Baseline calculator allows user to quickly change a model’s configurations and submit a re-calculation. Upon receiving an error message with the provided configurations, users can edit the model and change the configurations based on the guidance provided earlier. Then submit the model re-calculation to generate a new baseline analysis.
  1. Select the desired model under the
    Model Name
     list.
    The Baseline Calculator displays the Baseline Model parameters.
  2. Click
    Edit
     and change the parameters as required.
  3. Click
    Save
    .
    The last updated time stamp will be updated at the bottom.
  4. Click
    Recalculate
     to perform the baseline calculations with the new changes.
    NOTE:
    On recalculating the baseline analysis, the regression analysis does not change unless the model changes are saved.
