Load management involves an energy user who manipulating their load to reduce the demand they are putting on the electrical transmission and distribution network. This is typically done for one of three economically- driven reasons: to avoid incurring a peak demand surcharge on their utility bill to respond to a curtailment request from their local energy supplier (or independent system operator) if they are taking part in a demand response program to take advantage of a special tariff or rate schedule structure. Load Management

Load Management: Load Scheduling Utilities often have different rates (tariffs) that apply for different times of the day. Many large energy customers will often reschedule selected loads to different times of the day in order to: take advantage of lower rates avoid setting a new peak demand Load scheduling example

Utilities structure the energy billing for large customers with various components. One component is the charge for the total amount of energy the customer has consumed during the billing period. Many utilities also add another component called the demand charge, which is normally based on the peak usage the customer experienced at some point during a preceding period, typically a month, a season or a year. Load Management: Peak demand reduction

Two important aspects of demand charges: Once a demand peak is set, it can apply to every customers energy bill for up to a year in terms of calculating penalties. Demand is generally calculated using aggregated intervals, not real- time data. This gives the customer time to react to the readings as each interval is measured.

Alarming and Events As a general statement, alarm and event management is a means of risk management and is a core element of the end users need to maintain high reliability and constant power to the critical loads within a facility. Systems that provide these functions can be as simple as a single meter that sends an message and maintains a log of event data, or as intricate as a network of hundreds of meters and other devices connected to one or more software systems with multiple users.

Alarming and Events Alarms are used to identify operational anomalies in the functioning of the electrical network and to notify appropriate personnel or systems Reactive Alarm The opening or closing of a relay can be used to trigger an alarm in the event of a tripped breaker condition Active Alarm A meter can be used to measure the load on a breaker and to trigger an alarm if the load exceeds a critical limit, such 60% or 80% of the rated capacity of the breaker. Predictive Alarm A meter, or the combination of a meter communicating with software, can compare loading, harmonic levels and temperature to indicate a high probability of a pending breaker trip.
