In the Endeavour Energy zone covering St Marys, benchmark rates sit around 28.9 c/kWh for usage and 103 c/day for supply. These are indicative figures; your retailer sets the actual rates on your plan.

Bills also vary based on household size, whether you have controlled load (such as a hot water system on a separate tariff), time-of-use vs flat-rate pricing, and any applicable discounts.

The right electricity plan depends on your household type, usage patterns, and whether you have solar. Here is what to look for in St Marys.
Renters
Look for no lock-in contract plans with no exit fees. Flexibility matters most if your lease is short-term.
Families
Focus on the lowest usage rate available. In the Endeavour Energy zone, rates start from around 22.1 c/kWh.
Apartments
Apartments tend to use less electricity. A low daily supply charge can matter more than a low usage rate for smaller households.
Solar households
Compare both usage rates and feed-in tariff rates. The best plan balances what you pay for grid electricity with what you earn from exporting solar.
Low-usage homes
If you use under 10 kWh per day, prioritise a low daily supply charge. Some plans offer lower supply charges in exchange for slightly higher usage rates.
High-usage homes
Prioritise the lowest usage rate. Large households, those with pool pumps, or homes with electric heating benefit most from competitive c/kWh rates.
