Configuring Energy Consumers¶

In this section of the configuration, you can define the assets in your plant that consume energy resources. These assets should already be defined in Insights Hub Asset Manager. Therefore, you can inherit the hierarchy structure that is defined there. Typically, all the variables required to enable the Energy Optimizer use cases should be defined on aspects within the asset. For more information, refer to Asset Manager documentation.

Adding a new Energy Consumer¶

In the "Energy Consumers" page, the full asset tree is shown on the left-hand side. Those assets are already configured and added to the Energy Optimizer application, as indicated by the green tick. For example, in the image below, the "Depositor" is already added as an energy consumer, whereas the "Continuous Oven" is not.

To add a new energy consumer, select the corresponding asset from the asset tree. First, add at least one energy media. Select the "Medium mapping" tab. 1. Click the 'Add new media' button and select a media from the list. These should already be defined in the Energy Resources section.

You have the option to define the Energy Consumer as a parent asset and to aggregate all of the energy media data from the assets below in the tree hierarchy. This is enabled by activating the slider ![Config-consumers-sub-asset](./images/config-consumers-sub-asset.png).

In this case you don't need to map the energy media to time series variables. Note that the "Parameter Mapping" tab is disabled, as the parameters from the sub-assets are used for the aggregation. If you select the sub-asset option, you can skip to step 4. Otherwise, proceed to 2.

1. Configure the time series variable mapping. Click "Select Parameter". The variable mapping dialogue has the current asset pre-selected, but it can be changed to any other asset, aspect and numerical time series variable on the tenant.
2. Select the appropriate aggregation method. First consider if the data for this resource is of type "Rate" or "Counter". A power or flow measurement, for example, would be of type "Rate", whereas energy or volume would be "Counter". If the data is a "Counter", select either "Absolute Counter" or "Difference Counter".
3. At this step, you have the option to save the mappings. You could also add another media following the previous steps. If you save the mappings, you then have the option to "Add to Energy Optimizer". The asset is then marked with the green tick to indicate that it has been added to Energy Optimizer.

At this stage, the time series data for the energy media will be imported into the application and basic features of analysis types such as Energy Efficiency become available. However, there is no context for the energy consumption. To provide production context and enable more useful insights into energy consumption, you need to define some parameter mappings.

Defining Parameters for an Energy Consumer¶

Switch to the "Parameter Mapping" tab. There is a list of optional parameters.

For each parameter you can decide whether it is defined for the consumer by checking the "Included" box. Then you must select a time series variable mapping and complete the configuration. The red border indicates that there is a missing configuration.

There are four optional parameters: 1. Reference. This is the number of product units that have been produced on the asset. It is needed to calculate the "per unit" values of the KPIs in analysis pages and the "size" of production batch data that are used in Predictive Models, for example. The "Reference" value can be aggregated as "Rate" "Absolute Counter", or "Difference Counter". Similarly to the energy media. 2. Batch. This is the variable used to aggregate the energy data into "batches". This aggregation is used in several features, including the Operator Alerts and Predictive Models. 3. Product. This is the time series for the product code that was being produced on the asset. It is needed to enable the product filter on the analysis pages. It is also used as an input for the predictive models. 4. Status. Define a time series variable corresponding to the asset status. This is used, for example; in the Energy Efficiency analysis. A status mapping needs to be defined already in the Status Mapping configuration. Select a status mapping from the dropdown to complete the configuration.

When all required variables are configured, ensure you click "Save mappings". In order to update the Energy Consumer data with this new context from these parameter mappings, you must click the "Import data" button.

After confirming, this will start the data import for the last 90 days of data from time series. The running import job is indicated by the symbol. Any time you make a change to the parameter configuration and save the Energy consumer then it will only be applied to new data by default. If you also want to update historical data for the last 90 days, then click again the "Import data" button and wait for the job to complete. You could also use this if you have updated time series data that you would like to reload.

!! note Any time you import the historical data, it will overwrite any existing analysis results.

At any time you can choose to remove the asset from Energy Optimizer. The energy media and parameter configurations remain saved so you can easily add them again if needed.
