About Energy events

Energy tracks and reports energy overconsumptions (Energy events) to facilitate the reduction of energy consumption, in much the same way that the Overview of Downtime module tracks and reports downtime events. In large facilities, the ability to identify and reduce over consumptions of energy can relate to large savings.

If you focus on the operational issues and the process as a whole, you can identify excess energy use in your process and take steps to reduce this excess energy use. To do this, you require an understanding of what your process is currently doing, so that you can determine if your plant is over-consuming. The primary goal is to increase the energy efficiency of your overall process.

Energy monitors energy demand (for example, kW) against a target and captures instances where the demand exceeds the target. Energy captures the start time, the end time, the amount of excess energy consumed, and other contextual information (for example, crew, shift, material, grade).

After the energy events are created and the amount of excess energy consumed is recorded, energy managers can perform root cause analysis. They can enter root causes and classifications to isolate recurring items of over-consumption and big incidents that cause over consumption. Plant teams can analyze this information and identify procedural changes and engineering projects to be certain that energy is consumed efficiently, while production performance is maintained or improved.

Examples

In the first scenario the energy is electricity. This illustration shows two 5-second time periods of energy overconsumption. The first Energy events shows an overconsumption of 1 MW above target usage, and the second event shows 0.5 MW above target. The combined overconsumption is 125kWh.

In the second scenario, the energy is water. The first event shows an overconsumption of 10 L/min. and the second event shows 5 L/min. above target. Therefore, the combined overconsumption of these two events is 1.25L.
