Australian households and small businesses expecting universal relief on their electricity bills from July 1, 2026, may be surprised by significant changes from major retailer Origin Energy. While overall usage charges are set to decrease for many, Origin customers in New South Wales and South East Queensland are being notified of daily supply charge increases of up to 100% from the start of the new financial year.
This development follows the Australian Energy Regulator’s (AER) final Default Market Offer (DMO) 2026-27 determination, which confirmed electricity price reductions for most customers on standing offers across NSW, South East Queensland, and South Australia. However, Origin’s adjustments highlight how individual retailer pricing strategies can impact the final bill, even amidst broader market trends of declining wholesale costs.
The Daily Supply Charge Shock
Origin Energy has begun contacting customers this week to inform them of pricing updates taking effect from July 1. For some customers on plans like the ‘Origin Go Variable’, the daily supply charge will jump from AUD$1.79 per day to AUD$2.69 per day. Other customers have reported increases from AUD$0.86 per day to AUD$1.72, or from AUD$1.28 to AUD$2.44 per day, representing increases of between 60% and nearly 100%.
These substantial increases to the fixed daily supply charge occur even as the variable usage charges per kilowatt-hour (kWh) are reduced. For instance, some ‘Origin Go Variable’ customers will see their ‘General Usage’ charge drop from 40.4 cents per kWh to 34.8 cents per kWh. An Origin spokesperson confirmed that changes vary by location and plan, and while overall bills are expected to be lower for most customers, the impact will depend heavily on individual electricity consumption patterns.
“We understand increases to supply rates and decreases to usage rates have created confusion for some customers,” an Origin spokesperson stated. “The impact on a customer’s bill will ultimately depend on how much electricity they use.”
DMO Reductions vs. Retailer Strategy
The AER’s DMO acts as a safety net, setting the maximum price retailers can charge residential and small business customers on standing offers. It also serves as a reference price for comparing market offers. For 2026-27, the AER announced the following residential flat rate standing offer price changes:
| State/Region | Flat Rate Change (Residential) | Estimated Annual Saving/Increase (AUD) |
|---|---|---|
| New South Wales | -3.4% to -5.0% | -$66 to -$137 |
| South East Queensland | -7.2% | -$155 |
| South Australia | +1.4% | +$33 |
For smart meter households on time-of-use standing offers, reductions were even more pronounced, ranging from a 1.1% decrease in South Australia (saving around AUD$25) to a significant 10.7% decrease in South East Queensland (saving around AUD$229). Small businesses also saw broad reductions across all DMO regions, with decreases up to 20.9% in some NSW zones.
However, only about 10% of households are on DMO standing offers directly. The majority are on market offers, where retailers like Origin set their own rates, often using the DMO as a reference point. The current shift in Origin’s pricing structure – reducing variable usage charges while increasing fixed daily supply charges – reflects a strategy to manage wholesale energy costs and network costs differently. Network costs, which cover poles and wires, contribute roughly 40% to bills and are subject to ongoing review by bodies like the AEMC.
Who Benefits, Who Loses?
This pricing restructure will have varied impacts:
- High-consumption households: These customers, who use a large amount of electricity, are more likely to see overall bill reductions, as the decrease in usage charges could outweigh the higher daily supply fee.
- Low-consumption households: Households with minimal electricity use, or those with significant rooftop solar offsetting their usage, may find their total bills increase due to the higher fixed daily charge. This is because the fixed charge makes up a larger proportion of their total bill.
- Solar owners: While solar exports can reduce usage charges, the higher fixed daily supply charge still applies, potentially eroding some of the savings gained from self-consumption or feed-in tariffs.

The New Solar Sharer Offer
Adding another layer of complexity, the AER’s DMO determination also introduced the new Solar Sharer Offer (SSO). Available from July 1, 2026, in DMO regions (NSW, SA, SE QLD), this opt-in plan provides eligible households with smart meters three hours of free electricity in the middle of the day. This is designed to encourage shifting energy use to periods of high solar generation, benefiting both consumers and grid stability. Importantly, the SSO is available to households with or without rooftop solar.
While the SSO offers a compelling opportunity for savings by shifting demand, customers considering it must still navigate their overall electricity plan structure, including the daily supply charge.
What Australian Consumers Should Do
The changes underscore the importance of actively comparing energy plans. With varied price adjustments and new offers like the Solar Sharer Offer, remaining on a default or old market offer could mean missing out on significant savings. Consumers are urged to:
- Review your latest bill: Understand your current daily supply charge and usage rates.
- Assess your usage: Consider how much electricity you consume, especially during peak and off-peak times.
- Compare market offers: Use government comparison websites or contact retailers directly to find the best plan for your household’s specific consumption profile. For those struggling with bills, understanding available support is crucial. Navigating Australia’s Energy Bill Relief and Support in 2026: A Comprehensive Guide can provide valuable information.
- Consider smart energy solutions: Technologies like smart meters and home energy management systems (HEMS) can help optimise usage and take advantage of time-of-use tariffs or offers like the Solar Sharer Offer.

These latest changes from Origin Energy, set against the backdrop of the AER’s DMO, highlight a dynamic and increasingly complex energy market. Proactive engagement with energy plans and understanding billing components will be key for Australians looking to manage their electricity costs effectively from July 1, 2026.
