  so you, or your PowerLogic system, can take
  corrective action to eliminate penalties.
• Use your PowerLogic system to monitor power
  factor and control
• Capacitor banks
• Load tap changers
• Filter banks

9
Measurement and verification

• Realize maximum long term payback with a
  PowerLogic system and assure your energy
  efficiency investments are sustainable and
  adjustable.
• Benchmark against departments, processes and
  industry KPIs
• Forecast results to compare different benefit
  scenarios
• Document results so you can verify efficiency
  program financial benefits
• Baseline performance-based energy service
  contract results
• Validate utility bills, document errors and
  identify false penalty charges
• Minimize the negative effects energy efficiency
  initiatives may pose to people or productivity

10
Infrastructure optimization

• Extend equipment life with preventive and
  proactive maintenance
• Match maintenance with equipment specifications
• Track relay or breaker trips, UPS operations or
  remaining battery power automatically
• Utilize alarm on temperatures, performance
  parameters and wear indicators
• Reduce maintenance related labour costs
• Distribution system optimisation
• Reduce capital expenses associated with poor
  power distribution system utilisation
• Design power systems according to actual usage
  patterns
• Generate load profiles automatically
• Determine if your existing infrastructure will
  accommodate new processes

11
Demand response and load curtailment

• Curtailing loads at your utilitys request helps
  you negotiate lower electricity rates. A
  PowerLogic system provides the tools to help you
• Evaluate the economic advantage of participation
• Evaluate where, when and how much load should be
  shed
• Verify curtailment activities in real time
• Coordinate backup systems
• Manage loads remotely or automatically
• Verify contract compliance by all parties

12
Peak demand reduction

• Using PowerLogic technology to reduce peak demand
  offers a quick and easy way to lower your
  electricity bill through
• Automatic forecasting of energy consumption and
  demand
• Alerts that warn you when demand thresholds risk
  being exceeded
• Isolating specific power-intensive activities
  that you may choose to reschedule to off-peak
  hours
• Sequencing of motor and HVAC to startup to
  reduce instantaneous demand
• Automatic load shedding or on-site generation
  start-up

Load Management

• 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.

17
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

18
Load Management Peak demand reduction

• 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.

19
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.

20
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 e-mail
  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.

21
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.
