Percentage of Energy (POE) is an important metric used to allocate total energy consumption to specific products, processes, or production lines. Under EECA 2024 reporting, POE helps organisations determine how energy is distributed across production activities and supports the calculation of Specific Energy Consumption (SEC).
For facilities with multiple products or production lines, selecting the right POE estimation method is important to ensure the allocation is reasonable, consistent, and verifiable.
In this guide, we highlight six practical methods that can be used to estimate POE:
- Direct Submetering Method
- Equipment Load Apportioning Method
- Utility-Based Allocation Method
- Recipe / Batch Energy Allocation Method
- Multiple Regression Analysis Method
- Operating Hours Allocation Method
Each method has its own suitable application depending on the availability of metering data, equipment records, production information, operating hours, and historical energy data.
This guide is useful for Registered Energy Managers, energy auditors, facility managers, and organisations preparing for EECA 2024 energy reporting.
