Controlling Energy Use and Demand
The volume and accuracy of energy use information gathered in the preceding phases is useful in determining the next
steps. Perhaps an automated demand control system would be effective in increasing energy efficiency and sustainability.
Opportunities for heat recovery and on-site generation may be identified. Potential trouble spots might be avoided that
would minimize unnecessary downtime.
Once critical energy consumer's design or target consumption levels are defined, one then needs to be able to measure it.
Once the underlying infrastructure is in place to understand where and how energy is being consumed, it is easier to
formulate a strategy that lets you transition into the three core steps of energy management: Monitor, Analyze, and
Control.
Monitor and Measure
Effectively monitoring energy and power quality includes power monitoring smart devices that can capture and
communicate energy consumption information.
Know What to Measure
These devices are used to measure energy parameters associated with a specific system. For electricity, it can be a bus in a
facility's electrical distribution system, allowing plant managers to gather detailed information on power consumption in
different areas of their plants, on specific machines and even on individual product lines. In addition to usage data, these
smart power monitoring devices offer access to power quality information that can improve productivity and lengthen
equipment life.
Through the use Rockwell Automation® power monitor units, controllers, and data collection software such as
FactoryTalk® EnergyMetrix™, plant floor energy usage is measured and monitored in real time to help you understand
usage patterns, optimize processes, and reduce utility costs in your organization. You can use these tools to monitor
electrical loads, consumption, power quality, analyze demand, and generate billing and cost allocation reports. The
following are some of the monitoring capabilities:
Consumption Reporting
Consumption reporting typically monitors periodic utility usage, production, or other key performance indicators, and
assists with the early detection of production/equipment problems such as leaks, inefficiencies, and production
problems.
Demand Analysis
Demand analysis monitors the electrical demand of plant areas so that you can make energy saving production
scheduling or demand control decisions.
Submetering
Sub-metering is the practice of deploying power meters to monitor individual loads or work cells. A sub-metering
strategy lets you measure differences in power consumption from shift-to-shift or line-to-line to provide internal cost
allocation. Sub-metering gives companies the ability to reward a specific group or department within a plant that
implements successful energy saving initiatives.
