Why do electricity prices differ across Western Australia?
WA electricity bills have risen approximately 3.5% over the past year, with the average annual household bill now sitting at $1,490. Several factors drive variation within the state:
- Distribution network: Your local distributor's network charges vary by region within WA. Metropolitan areas often have different distribution costs to regional or rural areas.
- Retailer margin: Each retailer adds its own margin to the wholesale electricity cost and network charges. Smaller or newer retailers sometimes offer sharper pricing to attract customers.
- Usage tier structure: Some plans charge different rates depending on how much electricity you use. High-usage households may benefit from plans with a lower step-one rate.
- Contract type: Fixed-rate plans lock in a rate for 12–24 months, while variable plans can change. Fixed plans offer price certainty; variable plans sometimes offer lower rates but can increase.
- Solar feed-in tariff: If you have rooftop solar, the feed-in tariff rate affects your net bill. Comparing both the usage rate and the feed-in rate is important for solar households.
