Energy Intelligence - Sustainable Savings

PyramidStudies show that the greater and the more detailed the understanding of how and when energy is being used, the greater the ROI and the shorter the Payback on energy conservation projects and energy saving measure installations.

The ultimate objective is to be able to monitor and manage each load and device in the facility. This can only be achieved through adoption of new and innovative  management practices and implementation of a systematic resource and energy management process we refer to as Energy Intelligence.

To gain a better understanding, we must begin with asking a series of questions about load breakdown and energy use:

  1. What are the actual loads?
  2. How many kW does each load use?
  3. What are the run-time patterns for each load?
  4. Are there any redundant and non-essential loads that could be shut down during certain times of day?
  5. What time of day does the load run most?
  6. What is the average kWh consumption; per month, per day, per hour of operation?
  7. What is the typical Load Factor?
  8. When does overall Peak Demand happen; time of day, day of week, day of month?
  9. Are electric motors properly sized? Is a 75HP motor is sufficient where a  100HP motor is being used?
  10. Could a Variable Speed Drive be used with certain electric motors that have variable loading?
  11. Is Compressed Air being used efficiently?
  12. Are the Compressed Air motors properly sized?
  13. What is the optimal PSI for the Compressed Air System?
  14. Are there leaks in the Compressed Air System that could be fixed?
  15. Are Refrigeration Chillers and HVAC systems running efficiently?
  16. Is Lighting adequate and is it efficient in terms of Lumens/Watt?
  17. How efficient is the Electrical Distribution System?
  18. Are transformers overloaded and overheating?
  19. Is low Power Factor at the load causing Reactive Energy Losses and Distribution System Losses?
  20. Is low Power Factor causing extra billing cost due to penalties?
  21. Are the Non-Linear loads causing energy losses due to Harmonics?
  22. Are there unscheduled shutdowns or are there electronic equipment failures due to random breaker tripping?
  23. How much energy savings was actually achieved with previous energy efficiency measures and projects.
  24. What were the ROI, NPV and Payback of previous energy efficiency projects?
  25. What is the amount of kWh used during a typical product production run?
  26. What is the typical cost of energy per unit of production (kWh/Unit)?
  27. What are the Key Performance Indicators and benchmarks in terms of Energy Intensity?
  28. What is the performance of a load or a production system in terms of energy intensity (kWh/Hr) as bench-marked against other similar loads, other plants or industry standards?
  29. Could Operational Energy Savings be achieved by making changes to operational processes with a view to reducing the process energy intensity relative to your benchmarks?
  30. Could Maintenance Savings be achieved by early detection of possible maintenance issues that are indicated when benchmark performance of a load diminishes?

EnergyConservationCircleSm1To find the answers to the above questions, it is necessary to adopt a systematic approach to energy and operational efficiency. Continuous efficiency improvements can be achieved by implementing the following steps and components:

  1. Energy Studies
  2. Monitoring & Targeting (M&T)
  3. Efficiency Measures & Incentives
  4. Measurement and Verification (M&V)
