What is the AEMC proposing on fixed charges?

The AEMC is considering a rule change that would move a larger share of network costs into fixed daily charges, and reduce the portion linked to energy used. The goal is to align cost recovery with network cost drivers. If adopted, retailers would reflect new tariffs in offers over time.

How could this affect rooftop solar payback?

Higher fixed charges reduce the bill savings from each kilowatt hour not bought from the grid, so payback periods for rooftop solar can lengthen. The impact varies by state, retailer plan, feed-in rate, and whether a home has a battery. Some households will still benefit, but savings may narrow.

What might low-income customers experience?

Low-use customers, including many low-income households and apartment dwellers, could face A$100 to A$200 higher annual bills under the estimates reported. Actual outcomes depend on usage, concessions, and chosen plan. Comparing offers and checking eligibility for rebates can soften the impact on low-income energy bills.

When could changes show up on bills?

Submissions close on 13 February 2026. The AEMC would then consider feedback, issue a draft decision, and later a final decision. If a rule proceeds, networks propose tariffs for AER approval, then retailers update plans. Bill impacts could phase in from late 2026 and beyond, differing by state and retailer.

Australia Power Bills February 13: AEMC Push to Lift Fixed Charges

ByDanny Kontos February 13, 2026February 13, 2026

As submissions close today, the AEMC plan to lift fixed charges across the australian electricity network is in focus for households and investors. The shift would move more network costs into daily fees, rather than usage. Analysts say this could add A$400 to A$700 a year for solar and battery homes, and A$100 to A$200 for low-use customers. We review the possible bill impacts, rooftop solar payback, retailer pricing moves, and what the next steps may mean for regulated returns across the National Electricity Market.
