PEM (Predictive Energy Management)

Daily peak load management is the practice of operating a facility to reduce time‐of‐use or peak demand charges. Typical peak load management methods include demand limiting and demand shifting.

Demand limiting refers to shedding loads when pre‐determined peak demand limits are about to be exceeded. Loads are restored when the demand is sufficiently reduced. This is typically done to flatten the load shape when the pre‐determined peak is the monthly peak demand.

Demand shifting is shifting the loads from peak times to off‐peak periods. While not always the case, standard notification requirements, workforce considerations, and supplier schedules often result in load shifts at industrial facilities occurring later than required; thus missing the opportunity for cost reduction.

The E2M-enabled PEM service instantly provides the business intelligence for operations to prepare, and then implement the cost reduction opportunity.

In grid connected Western Australia, up to 40% of electricity costs can be due to the network costs imposed by Western Power and their ‘Rolling Peak Demand’ tariff calculations. Limiting and shifting demand to avoid Peak tariffs can result in a significant reduction in costs.
