You're faced with discrepancies in energy consumption data. How will you effectively manage the situation?
When faced with energy data inconsistencies, swift and accurate management is key. To resolve this issue:
- Verify the accuracy of meter readings and data entry to pinpoint errors.
- Compare against historical usage patterns for anomalies.
- Engage with your utility provider to clarify and correct any discrepancies.

How do you approach discrepancies in energy consumption data?
-
1. Validate readings and entries to catch errors. 2. Compare with historical data for anomalies. 3. Contact the utility provider to resolve any unexplained discrepancies

Few suggested iterations on checking for the; - Energy supply - Energy consuming - Energy recording -Equipment’s 1-accuracy benchmarking 2-missed maintenance schedule 3-Working environment breach 3-Recording and analysing breach.

1. involve the utility companies and ask them to install another calibrated meter 2- some high consumption equipment/ machines may be consuming more power due to being old or operating faulty - Always advisable to install sub-meter at high power consuming machines or sub-locations . 3. Keep validating with historical data OR consumption in relation with productivity- productivity / unit . 4. Power factor check. New installed equipment may have different harmonics- KVA/ KVAR/ KWH should also be checked. 5. check records of the calibrations of meters and equipment’s maintenance intervals.

I recommend using the scientific method IPMVP (International Performance Measurement and Verification Protocol) Option 3. Start by verifying data accuracy, checking for errors in measurement or the entry. IPMVP Option 3 allows you to analyze whole-building performance, comparing energy use before and after implementing efficiency measures. Engage stakeholders for insights, as they may highlight trends or anomalies. Review your energy management systems (EMS) to ensure its calibrated correctly. Document findings for future reference, and establish a continuous monitoring system to catch anomalies early. Regularly review your processes to identify improvements, strengthening your overall energy management strategy.

Data is numbers but understanding of the process is key. What would be the typical energy usage of your process. Is the number on the screen reflective of the typical conditions? Diving deeper into metering, is the measurement element sending a correct signal to the transmitter. When was the meter last checked for accuracy. Is the data used for billing purposes or tracking purposes. How would you bundle any corrective maintenance with planned shutdowns to achieve economies of scales. These are the questions to ask if one is to validate energy consumption data.
