Rockwell Automation's RSEnergy Metrix (TM) software is a comprehensive web based application that allows you to log and analyze energy data. It works just as well for a small plant with one or two Power Monitors as it does for a large corporation with dozens of plants and hundreds of meters. Anyone with access to your corporate network can access the system through their web browser with the proper log in credentials.

After completing dozens of installations in a wide variety of industries, UtilEcon Services has a real edge when it comes to shortening your learning curve cycle. Our training program shows you where the important information resides on the system and how to use it. Click here for a table showing of the electrical data we typically log into the system. Here are a few examples of how that data can be used to reduce energy costs:
Demand management is a great place to start managing energy as it
typically constitutes 30 to 40 percent of large electric bills.
When power monitors log electrical data into the
RSEnergy Metrix software by transformer, each sub's contribution to
plant wide demand can be observed clearly, as shown here:
The red line in the chart displays total plant wide demand. The orange, blue and green lines represent demand from individual sub-stations. Note the orange and blue lines tend to run at a fairly constant level during daily production hours.
The green line, however, only "pops-up" intermittently along the x-axis. When it does, total demand (red) tends to reach its highest peak. If the green line load could be rescheduled to run during a back shift or when either of the other two subs are not at full load, total demand for the month could be reduced.
The Calendar Trend screen provides a quick glance at an entire month of data. Kilowatts of demand are shown here but most any parameter can be viewed. If demand spikes abnormally it will be easy to spot in this view. Green shading highlights days to compare.
The monthly demand picture can be expanded to daily by simply clicking on the day(s) in question. When this occurs, a 24-hour window shows the demand profile in 15 minute intervals. Up to five days can be displayed, each with a different pen color.

This is a great tool for comparing demand profiles between different days. Spikes or unusual demand patterns can overlay normal profiles at the click of a mouse.
Meter data can be displayed for the entire plant or any group of meters. Graphs can be printed or exported for further analysis.

Monitoring and bench-marking kilowatt-hour consumption during periods of of lower
consumption presents an opportunity for RSEnergy Metrix (TM)
to curb energy waste. Using the Trend screen allows us to chart kilowatt-hour
consumption by day as shown here:
Notice the usage levels on January 2nd and 3rd reflect a holiday shutdown. The weekend of the 15th shows usage for a typical weekend. However, the weekend of the 8th and 22nd show an abnormally high level of consumption as compared with the other two. There may be a valid reason for this such as extended production. If not, this is an opportunity to identify waste and track future weekends to the benchmark established on the weekend of the 15th.
One of the unique features of the Rockwell Power Monitors (TM) is their ability to capture a signal from other pulse meters. These meters can measure gas, water or any other fluid that is material to your operation. The consumption of these utilities is tracked on the same time line as your electric power.
Looking at a 24 hour window on the Trend screen allows one to see this type of consumption at a 15 minute interval of resolution. Usage patterns for individual shifts can be clearly differentiated. Here is an example of a gas furnace ramping up for production from an warm idle mode.
The optimum temperature will most likely vary with the length time between runs. Determine the difference in the before and after amount of gas used and multiply by the number production runs to determine savings over time.
RSEnergy Metrix (TM) software has the ability to show energy cost by meter, or group of meters, over any time frame. Energy cost per year, quarter, month, week, day or even shift is readily available. If you install a new piece of equipment on your production line, you can see the impact it has on energy cost tomorrow, not next month. If you are trying to implement energy conservation changes, immediate feedback is available for reinforcement or correction.
UtilEcon Services provides complete programming of your electric tariff or rate schedule into the software as part of our turnkey installation. If you are logging water or gas usage, tariffs for those utilities can be programmed as well. Although tariff structures remain relatively constant, actual rates do fluctuate frequently. We offer a Rate Schedule Maintenance Service as a practical way to keep rates up to date and cost reporting accurate.
If you would like to learn more about how the RSEnergy Metrix (TM) software works we can provide an on-line demo of the system in operation. Please contact us if you would like to schedule a webinar demonstration.
