TL;DR: Simply Energy usually competes harder on price and on solar feed-in rates. Origin has the broader service range, bundling, and a more consistent support experience. Neither wins outright, because the answer changes by postcode and by how much power you actually import against export.
The Two Retailers
Origin is one of the three largest energy retailers in Australia, selling electricity, gas, internet and mobile across most states. Long-established, wide plan range, and enough scale to run proper support infrastructure.
Simply Energy is smaller and competes mainly in Victoria, New South Wales, South Australia and Queensland. It has built its position on sharper base rates, simpler plan structures, and feed-in tariffs that have often sat above the major retailers.
That difference in size shapes everything else. A large retailer competes on breadth; a smaller one competes on price, because it has to.
What Actually Determines Your Bill
Four numbers, in roughly this order of importance for a solar household.
Daily supply charge. A fixed daily fee regardless of consumption. Solar does not touch it. For a household that has driven its imports right down, it can be the largest line on the bill.
Usage rates. What you pay per kilowatt-hour imported. Still the biggest number for most solar homes, because almost nobody exports more than they import across a full year.
Feed-in tariff. The credit for exported surplus. Important, and consistently over-weighted in these comparisons.
Discount conditions and benefit period. Whether a discount depends on paying on time, and when the introductory rate reverts. Most benefit periods run 12 months and the reversion is rarely favourable.
Contract terms and exit fees matter too, and green power options if that is part of your decision.
Origin: The Established Retailer
Origin's advantages are structural rather than price-based.
Bundling. Combining electricity, gas and internet produces discounts that a single-service retailer cannot match. If you want one bill and one provider, that has real value.
Support infrastructure. Phone, chat and app, with the staffing to run them. Not always fast, but consistent, and the escalation path exists when something goes wrong with a solar connection or a metering fault.
Plan range. More options, including tiered feed-in offers and virtual power plant programs for battery owners.
On solar specifically, Origin's feed-in rates sit mid-market. Some plans pair a higher feed-in rate with a higher usage rate or supply charge, so the headline number tells you very little on its own. Read the plan documents rather than the marketing page.
The conditional discounts are worth attention. A discount contingent on paying on time is worth its full value only if you always pay on time, and losing it once on a quarterly bill is a meaningful amount.
Simply Energy: The Price Competitor
Simply Energy's pitch is straightforward: cheaper rates and better export credits.
Base rates. Usually competitive on usage charges, and often on the daily supply charge, which matters most for low-import solar households.
Feed-in tariffs. Historically among the stronger offers in several states. For a household exporting a genuine surplus, that is a direct advantage.
Simpler plans. Fewer tiers and fewer conditions, which makes the bill easier to check and the comparison easier to run.
The trade-off is service depth. A smaller retailer has fewer support channels and less redundancy when something unusual happens, and reviews vary by region more than they do for the majors. If your installation is straightforward and your billing is uneventful, that rarely matters. If you are dealing with a metering fault or a disputed export reading, it can.
Head to Head
Price. Simply Energy more often, particularly on usage rates. Origin can close the gap with bundling and conditional discounts, but only if you use the other services and meet the conditions.
Solar feed-in. Simply Energy has the edge in most states, though check for daily export caps on the better rates.
Service. Origin, on infrastructure and consistency.
Bundling. Origin, comfortably. Simply Energy does not compete here.
Green options. Both offer accredited GreenPower. Close to even.
None of these are permanent. Retailers reprice constantly, and a comparison from last year tells you nothing about this year's offers.
How to Actually Decide
Pull your last four bills and write down three numbers: total imported kWh, total exported kWh, and how imports split across peak, shoulder and off-peak if you are on time-of-use.
Those three numbers determine which retailer suits you.
- Import much more than you export, which describes most households with solar panels: prioritise the import rate and supply charge. The feed-in tariff barely moves your total.
- Export a large surplus, typically a big array with low daytime consumption: the feed-in rate earns real money, and Simply Energy's offers usually deserve the first look.
- Very low imports, usually a battery household: chase the lowest daily supply charge you can find and accept a higher import rate.
Then run those figures through Energy Made Easy, the federal government's free comparison service, or Victorian Energy Compare if you are in Victoria. Both are independent and take no commission. Enter your own usage rather than accepting a default profile, and specify that you have solar.
Do it again every twelve months. Benefit periods lapse quietly, rates move, and the plan that was competitive when you signed usually is not two years later.
Key Takeaways
- Simply Energy generally competes better on usage rates and solar feed-in tariffs; Origin offers broader services, bundling and more consistent support.
- The daily supply charge and import rate move a solar household's bill more than the feed-in tariff does.
- Check any feed-in offer for a daily export cap, because a high rate on the first few kilowatt-hours is worth little.
- Conditional discounts are only worth their headline value if you reliably meet the condition every billing period.
- Compare on total annual cost with your own usage data through Energy Made Easy or Victorian Energy Compare, and repeat annually.
