The recent trend of higher energy prices has caused a number of responses in the market. The first is for facility operators to look for lower cost energy. Put another way, facility operators will not look at conservation, or operations practices or replacement of capital equipment as a first step. Purchasing commodity at a lower cost is a typical and valid first means to achieve energy cost reduction.
With energy prices rising relative to other budget items such as labor and health care, facility owners are looking further at energy use. An Energy Management Information System (EMIS) is a tool that yields substantial amounts of useful data regarding facility energy consumption and performance.
Example of Energy Management Information System capabilities
1. Monitor multiple circuits at sites
2. Internet based enabling you to see real time, parameter reports on-line
3. Multiple 20 electrical parameters monitored online
4. Digital meters of high quality certified internationally
5. Automation of equipment is doable on request, although not a standard feature
6. T&D loss tracking for quantifying costs of reactive current due to internal resistance of
wiring as a percent of total consumption.
7. Breaker Status monitoring for instant response to shop breakers openings
8. Phase load balance reporting for re-balancing phases
9. Non electric monitoring for pressure, flow, temperature for energy consumption
10. Load control for taking advantage of TOD rates and internal cogenerations supplies
11. Monitor power quality voltage and frequencies for cutting costs of high neutral current,
harmonics.
12. Process control monitoring for taking stand-alone data from process machinery and
calculating optimum energy usages.
13. Fuels usage efficiency
14. Costing of process products per unit
15. Reduce maximum demand – which will help in those few places still needing help.
16. Equipment efficiency reporting – cooling towers, compressed air, refrigeration, fans
17. Load factor for each shop and facility for benchmark comparisons per square foot.
18. Predictive maintenance for cost-effective replacement of obsolete equipment
19. Root cause analyses
20. Verification of cogen reduced carbon footprint
