Energy Tracking in Alberta
This document discusses obtaining and analyzing utility energy data from various sources to track energy usage and costs. It outlines a three step process: 1) Obtain raw utility data from sources like utilities and gas companies, 2) Prepare the data by sorting and normalizing it, and 3) Extract meaning from the data by manipulating it in Excel or importing it into software to compare usage over time, between facilities, and to historical averages to identify equipment issues or energy reduction opportunities. The end goal is to have accessible and meaningful reports on facility, meter, and municipal energy usage and costs.

- 17. Step 2: Preparedata files
- 18. DCM • Sort byTrans Date • Keep all rows from last update • Key column: “Usage (kWh)”
- 19. DIM • Sort byDate • Keep all rows from last update • Key column: “kWh” • Be aware: hourly data, not daily data
- 20. Delivery Cost • Sortby Invoice Date • Keep all rows from last update
- 21. Energy Cost • Sortby Invoice Date • Keep all rows from last update • Ignore Consumption
- 22. Load • Sort byTo Date • Keep all rows from last update • Key column: “Metered Demand (kW)”
- 23. PF • Sort byTo Date • Keep all rows from last update • Key column: “Metered Power Factor”
- 24. Excel **Month Normalization** • Rawutility data is organized by READ DATE • Meters are read sporadically throughout the year • Usage and cost data is for reading period (ex: September 11 - October 15) • Need usage PER MONTH for meaningful tracking
- 25. Excel **Month Normalization** • Example: –60 GJ from August 20th to September 10th – 80 GJ from September 11th to October 15th – Therefore usage in September: 60 GJ * (10 days / 22 days) + 80 GJ * (20 days / 35 days) = 73 GJ September Period 1 Period 2
- 26. Step 3: Extract meaningfrom data
- 27. 1. Manipulate withExcel, or 2. Import into self-managed software, or 3. Work with an energy tracking and data visualization consultant 3 main options:
- 28. • Compare betweenfacilities – Identify energy reduction candidates • Compare to history – Catch spikes in usage for investigation (equipment malfunctions can cost $$,$$$.$$) • Factor in climate • Have facility/meter cost & usage at fingertips • Have municipality cost & usage at fingertips Desired Outputs
