Across global manufacturing industries, energy consumption is rising while energy prices remain volatile. At the same time, manufacturers face increasing pressure to reduce operating costs, improve sustainability metrics, and maintain consistent product quality. In this environment, energy efficiency is no longer optional\u2014it is a strategic imperative. <\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Despite this reality, many plants still operate with limited visibility into energy usage. Utility bills provide a monthly total, but they do not reveal which machines consume the most energy, when demand peaks occur, or how process changes affect consumption. Without this level of detail, optimization efforts are often based on assumptions rather than facts. <\/p>\n\n\n\n

A well-known principle applies: you can\u2019t optimize what you don\u2019t measure<\/em>. Energy monitoring addresses this challenge by providing continuous, granular insight into how energy flows through a facility. When energy data is captured at the equipment and process level, it becomes possible to identify inefficiencies, balance loads, reduce peak demand charges, and link energy consumption directly to production output. <\/p>\n\n\n\n

For process manufacturers\u2014particularly in feed mills and pelleting operations\u2014energy monitoring is especially valuable. These environments rely heavily on motors, grinders, pellet mills, fans, compressors, and steam systems, all of which are energy-intensive and subject to wear, variability, and operational trade-offs. Energy monitoring enables manufacturers to understand these trade-offs and operate closer to optimal conditions. <\/p>\n\n\n\n

Understanding Energy Monitoring <\/h5>\n\n\n\n

Energy monitoring is the continuous measurement and analysis of energy consumption across machines, processes, and systems within a manufacturing facility. Its purpose is to provide real-time and historical visibility into energy use so operators, engineers, and managers can make informed decisions. <\/p>\n\n\n\n

At its core, energy monitoring answers three critical questions: <\/p>\n\n\n\n

    \n
  1. How much energy is being used?<\/strong> <\/li>\n\n\n\n
  2. Where is that energy being consumed?<\/strong> <\/li>\n\n\n\n
  3. Why is consumption changing over time?<\/strong> <\/li>\n<\/ol>\n\n\n\n

    By answering these questions, manufacturers gain the insight needed to improve efficiency, reduce costs, and support long-term operational goals. <\/p>\n\n\n\n

    Understanding Energy Monitoring <\/h5>\n\n\n\n

    An effective energy monitoring system typically includes: <\/p>\n\n\n\n

      \n
    • Sensors and Meters<\/strong> \u2013 Devices that measure electrical parameters such as voltage, current, power, and energy. <\/li>\n\n\n\n
    • Data Acquisition<\/strong> \u2013 PLCs, I\/O systems, or networked devices that collect and transmit data. <\/li>\n\n\n\n
    • Data Historian<\/strong> \u2013 A centralized repository that stores time-series energy data for analysis and reporting. <\/li>\n\n\n\n
    • Visualization and Analytics<\/strong> \u2013 Dashboards, trends, and alarms that turn raw data into actionable insight. <\/li>\n<\/ul>\n\n\n\n

      Together, these components provide both real-time visibility and long-term performance tracking. <\/p>\n\n\n\n

      Energy Monitoring Technologies<\/p>\n\n\n\n

      High-Level Power Monitors<\/strong> <\/p>\n\n\n\n

      Advanced power monitors, such as Phoenix Contact EMpro devices or Allen-Bradley PowerMonitor 5000 units, go beyond basic electrical measurement. In addition to voltage, current, power, and energy consumption, these devices can: <\/p>\n\n\n

      \n
      \"\"<\/figure>\n<\/div>\n\n\n
        \n
      • Detect voltage drops and fluctuations <\/li>\n\n\n\n
      • Identify phase loss conditions <\/li>\n\n\n\n
      • Track power factor performance <\/li>\n\n\n\n
      • Compare measured energy usage to utility billing data <\/li>\n<\/ul>\n\n\n\n

        This level of insight helps manufacturers identify power quality issues, inefficiencies, and billing discrepancies that would otherwise go unnoticed. <\/p>\n\n\n\n

        VFDs and Soft Starters with Communication<\/strong> <\/p>\n\n\n\n

        Variable Frequency Drives (VFDs) and soft starters equipped with Ethernet\/IP or similar communication protocols are powerful energy monitoring tools. In addition to controlling motor speed and torque, modern drives can report: <\/p>\n\n\n\n

          \n
        • Real power (kW) <\/li>\n\n\n\n
        • Energy consumption (kWh totalizers) <\/li>\n\n\n\n
        • Apparent power (kVA) <\/li>\n\n\n\n
        • Reactive power (kVAR) <\/li>\n\n\n\n
        • Power factor <\/li>\n\n\n\n
        • Per-phase current and voltage <\/li>\n<\/ul>\n\n\n\n

          Even non-networked VFDs often provide a 4\u201320 mA analog output representing power, allowing integration with PLC systems. <\/p>\n\n\n\n

          This data enables detailed analysis of motor load, efficiency, and energy intensity at the equipment level. <\/p>\n\n\n\n

          Power Transducers <\/p>\n\n\n\n

          High-Level Power Monitors<\/strong> <\/p>\n\n\n

          \n
          \"\"<\/figure>\n<\/div>\n\n\n

          For motors and loads that are not controlled by VFDs or soft starters, power transducers provide a cost-effective solution. These devices output an analog signal proportional to real power consumed, allowing manufacturers to monitor legacy equipment and gain insight without major upgrades. <\/p>\n\n\n\n

          <\/p>\n\n\n\n

          Business Impact: Cost Reduction and Efficiency<\/strong> <\/p>\n\n\n\n

          Identifying Inefficiencies<\/strong> <\/p>\n\n\n\n

          Energy monitoring makes inefficiencies visible. Motors running unloaded, equipment left idling, poorly tuned processes, and worn components all reveal themselves through abnormal energy patterns. Once identified, these inefficiencies can be corrected through operational changes or targeted maintenance. <\/p>\n\n\n\n

          Quantifying ROI<\/strong> <\/p>\n\n\n

          \n
          \"\"<\/figure>\n<\/div>\n\n\n

          For motors and loads that are not controlled by VFDs Small efficiency improvements can yield significant financial returns. For example, a 2\u20135% reduction in energy consumption across a large feed mill can result in substantial annual savings. Energy monitoring provides the data needed to quantify these savings and justify investments in equipment upgrades, automation, or process changes. <\/p>\n\n\n\n

          Load Balancing and Scheduling<\/strong> <\/p>\n\n\n\n

          By understanding when energy demand peaks occur, manufacturers can adjust production schedules to avoid unnecessary demand charges. Load balancing across multiple lines or processes further reduces strain on electrical infrastructure and lowers operating costs. <\/p>\n\n\n\n

          Practical Applications in Feed and Pellet Manufacturing <\/p>\n\n\n\n

          Grinding Operations<\/strong> <\/p>\n\n\n\n

          Grinding is one of the most energy-intensive processes in a feed mill. Energy monitoring supports several optimization strategies: <\/p>\n\n\n\n

            \n
          • Controlled Ramp-Up<\/strong> \u2013 Slowing motor ramp-up reduces inrush current spikes and prevents demand penalties. <\/li>\n\n\n\n
          • Energy per Ton Tracking<\/strong> \u2013 Monitoring kWh per ton helps identify hammer and screen wear. <\/li>\n\n\n\n
          • Product-Specific Strategies<\/strong> \u2013 Finer grinds consume more energy than coarser grinds; monitoring helps balance quality requirements with energy costs. <\/li>\n\n\n\n
          • System Design Improvements<\/strong> \u2013 Minimizing idle machinery and optimizing material flow reduces wasted energy. <\/li>\n<\/ul>\n\n\n\n

            In multi-product environments, energy data can also guide decisions such as avoiding simultaneous grinding of difficult materials on multiple mills. <\/p>\n\n\n\n

            Pelleting Operations<\/strong> <\/p>\n\n\n\n

            Pelleting presents its own energy challenges, and monitoring provides valuable insight: <\/p>\n\n\n\n

              \n
            • Start-Up Optimization<\/strong> \u2013 Slow ramp-up prevents current spikes and reduces mechanical stress. <\/li>\n\n\n\n
            • Die and Roll Condition Monitoring<\/strong> \u2013 Rising energy per ton often indicates worn dies or rolls. <\/li>\n\n\n\n
            • Steam Quality Management<\/strong> \u2013 Poor steam quality increases energy usage and reduces pellet quality. <\/li>\n\n\n\n
            • Cooler Fan Optimization<\/strong> \u2013 Adjusting fan speed based on actual demand reduces unnecessary power consumption. <\/li>\n\n\n\n
            • Formulation Awareness<\/strong> \u2013 Changes in formulation may reduce ingredient cost but increase energy cost; monitoring reveals the true impact. <\/li>\n<\/ul>\n\n\n\n

              Energy comparisons between new and worn dies and rolls clearly illustrate the cost of delayed maintenance. <\/p>\n\n\n\n

              Compressed Air and Steam Systems<\/strong> <\/p>\n\n\n\n

              Compressed air and steam often account for a significant portion of total energy use: <\/p>\n\n\n\n

                \n
              • Compressed Air<\/strong> \u2013 Energy monitoring helps identify air leaks and unnecessary usage, such as continuously running vibrators or baghouses. <\/li>\n\n\n\n
              • Steam<\/strong> \u2013 Tracking steam or natural gas usage per pellet run reveals inefficiencies and supports better boiler management. <\/li>\n\n\n\n
              • Idle Equipment Shutdown<\/strong> \u2013 Automation can ensure fans, compressors, and conveyors shut down when not in use. <\/li>\n<\/ul>\n\n\n\n

                Energy Savings Through Automation and Control <\/p>\n\n\n\n

                Variable Frequency Drives<\/strong> <\/p>\n\n\n\n

                Adding VFDs is one of the most effective energy-saving strategies. Benefits include: <\/p>\n\n\n\n

                  \n
                • Speed control based on process requirements <\/li>\n\n\n\n
                • Reduced mechanical wear <\/li>\n\n\n\n
                • Lower energy consumption during partial load operation <\/li>\n\n\n\n
                • Elimination of unnecessary full-speed operation <\/li>\n<\/ul>\n\n\n\n

                  In hammermills and pellet mills, long ramp-up times prevent demand spikes, while low-speed operation between runs reduces wasted energy. <\/p>\n\n\n\n

                  Automation Strategies<\/strong> <\/p>\n\n\n\n

                  Automation amplifies the value of energy monitoring by enabling intelligent responses to energy data: <\/p>\n\n\n\n
