2. Alberta Bill Index (energy portion only, 600 kWh)
The energy-only portion of a typical household month (600 kWh) priced at the Rate of Last Resort in each utility zone and at Bright Fire's current 1-year fixed rate of 8.29 cents/kWh.
| Utility zone | RoLR | 600 kWh on the RoLR | 600 kWh on Bright Fire 1-year fixed | Difference |
|---|---|---|---|---|
| EPCOR Energy Alberta / FortisAlberta areas | 12.01¢ | $72.06 | $49.74 | $22.32 |
| ATCO Electric areas | 12.02¢ | $72.12 | $49.74 | $22.38 |
| Calgary (ENMAX Power wires area) | 12.06¢ | $72.36 | $49.74 | $22.62 |
What the index does and does not include
Energy charge only: 600 kWh multiplied by the rate. Delivery and transmission charges are set by your local wires company and are the same on every retailer, so they are not included. Administration fees (Bright Fire's is $9.99/month), rate riders, other retailer fees and GST are also not included, so these are not full bill totals. Variable plans are deliberately excluded from the bill math: a variable rate moves with the monthly market price, so comparing it with a fixed regulated rate is not apples-to-apples. The pool price in section 1 is reported separately as market data only. Your own usage will differ from 600 kWh.
3. What Moved This Week
- No hour reached $100/MWh. All 168 hours settled below $100/MWh, compared with six hours at or above that level the week before. The highest single hour was $95.12/MWh (9.51 cents/kWh) in the 7 a.m. hour on Thursday September 24, and Thursday was also the week's highest day at 4.81 cents/kWh.
- The 30-day average eased. The rolling 30-day average fell to 3.01 cents/kWh from 4.25 cents a week earlier. Daily averages ran from 0.95 cents/kWh (Monday September 21) to 4.81 cents/kWh (Thursday September 24). Five hours settled at $0.00/MWh: two on Monday September 21 and three overnight early Saturday September 26.
- Demand edged up. Alberta Internal Load peaked at 10,877 MW on Monday September 21 in the 6 p.m. hour, compared with a peak of 10,513 MW the week before. Average hourly demand was about 1% higher than the prior week (9,866 MW vs 9,734 MW).
All three points are read directly from the AESO Pool Price Report (hourly price and Alberta Internal Load). This report does not forecast prices and does not explain individual price hours; AESO publishes its own market commentary.
