Key Factors to Compare Electricity Plans in South Australia
When selecting the best electricity plan for your home, don’t just chase the lowest price — it’s important to check:
- Daily Supply Charges:
High supply charges can add up quickly, even for low-energy households. - Usage Rates (c/kWh):
Review both peak and off-peak rates if on a time-of-use tariff. - Solar Feed-in Tariffs:
If you have solar panels, a higher FiT (feed-in tariff) boosts your credits for exported solar energy. - Discounts & Promotions:
Some plans offer bonuses like pay-on-time discounts — but always check if the conditions are realistic. - Contract Terms & Exit Fees:
Flexible, no-lock-in contracts are safer if better deals emerge. - Billing Options & Extra Fees:
Avoid providers that charge hidden fees for paper bills, late payments, or card payments. - Green Energy Options:
Consider 100% renewable energy plans if sustainability matters to your household.
