report costs for buildings, departments,
processes, shifts, lines, or equipment
•
Compare efficiencies
•
Determine the true impact of
energy prices on production lines
•
Identify opportunities to better
balance consumption
•
Remove electricity budgeting guesswork,
minimize administrative costs
and reduce data entry errors
Procurement optimization
Use PowerLogic system information to negotiate bulk energy
purchases to reduce price volatility and lower energy costs:
•
Consolidate cost information
into easy to understand reports
•
Track real-time Internet pricing
•
Start generators or
shed loads at cost thresholds automatically
•
Integrate costs for fuel,
•
Maintain environmental levies, and interconnection
•
Participate in spot energy market programs
•
Compare purchasing options
Power factor correction
A PowerLogic system alerts you to adverse
trends 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
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
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
Demand response and load curtailment
Curtailing loads at your utility’s 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
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 economicallydriven 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 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
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.
Load Management: Peak demand
reduction
Two important aspects of demand charges:
•
Once a demand peak is set, it can
apply to every customer’s energy bill
for up to a year in terms of
calculating penalties.
•
Demand is generally calculated
using aggregated intervals, not realtime data. This gives the customer
time to react to the readings as each
interval is measured.
Peak reduction example
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 user’s 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.
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.
