Energy Allocation Scenario (Advanced with Unit Conversion)

One possible scenario in energy applications for manufacturing is the energy allocation scenario. In this scenario, we have a main meter supplying energy to say 2 or 3 areas and the way the energy is allocated on a per area basis is via “experience” or other indirect estimation by using percentages like:

10% in Area 1
30% in Area 2
40% in Area 3
20% in Area 4

For example, consider the case in the following screenshot, where Meter 1 and Meter 2, of BTU and kWH units are feeding with energy various areas and in one area (Paint) are combining as inputs.

Energy Allocation and Complex Asset Structure Support

In the proposed asset structure, we have two electric meters
One in BTU (allocates Paint (15%), Sinter (80%), Area X (5%))
One in kWH (allocates Panel (70%), Paint (30%))
We would like to rollup at the Plant level at BTU

Energy AnalytiX supports this scenario as follows, using the following asset structure and configuration steps:

We define Electric_kWH meter type (kWH), Electric_BTU meter type of BTU units and Total_BTU meter type (BTU) (virtual meter type).
We define energy asset Plant (rollup-based asset)
We define Plant Meters asset as a placeholder, add energy extension without adding any energy calculations.
We define Meter 1 of Electric_BTU type (BTU), Meter 2 of Electric_kWH (kWH).
We define energy assets (non-rollup) Paint, Sinter, Area X, Panel.

Energy Allocation Asset Structure

Energy Allocation Meter Types

We define energy calculations as follows:

Paint

Consumption for Total_BTU (virtual meter type) in BTU
Consumption = (Meter 2 consumption) * 0.30* (kWH to BTU factor) + (Meter 1 consumption) * 0.15

Sinter

Consumption for Total_BTU (virtual meter type) in BTU
Consumption = (Meter 1 consumption) * 0.80

Area X

Consumption for Total_BTU (virtual meter type) in BTU
Consumption = (Meter 1 consumption) * 0.05

Panel

Consumption for Total_BTU (virtual meter type) in BTU
Consumption = (Meter 2 consumption) * 0.70* (kWH to BTU factor)

Plant (rollup)

Consumption rollup for Total_BTU (virtual meter type) in BTU
Implicit definition (no need to manually sum up children asset consumptions)

Meter 1 Configuration

Meter 2 Configuration

Since we have defined several meter types as virtual, we can add energy consumption calculations in related assets where the calculation expression could involve consumptions from any of the two energy meters configured when adding energy calculations for the above meter types.

Note: If other electric type of meters are to be added, for energy analysis purposes, the Electric_kWH meter type convention should be maintained across the board.
