Why does it feel like every energy bill in Australia keeps climbing, and AGL’s in particular stands out as eye-wateringly expensive? The short answer: it’s a mix of wholesale energy costs, government policy shifts, infrastructure spending, and retail margins. But the longer story is more interesting — and revealing.

What drives AGL’s high prices?

1. Wholesale energy volatility
AGL buys a lot of its electricity from the wholesale market. Prices there can spike due to extreme weather, gas shortages, or outages at coal plants. When wholesale costs rise, retailers like AGL tend to pass them on to households.

2. Transition costs from coal to renewables
AGL has historically been one of Australia’s biggest coal power generators. Now, as it faces pressure to close coal plants earlier than planned, it’s investing heavily in renewables and storage. Those transition costs filter through to customer bills.

3. Network charges and infrastructure
It’s not just the electrons you’re paying for. Network costs — the “poles and wires” that move electricity — account for up to half of a typical bill. AGL doesn’t set those charges, but they’re bundled into what you pay.

4. Retail margins and brand dominance
As one of the “big three” retailers (AGL, Origin, EnergyAustralia), AGL has scale and market power. Critics argue this reduces competitive pressure, letting them hold prices higher than smaller rivals.

Is AGL more expensive than smaller retailers?

Often, yes. Independent price comparison data regularly shows challenger retailers offering cheaper plans. These smaller players typically operate with leaner overheads and aggressive discounts to win customers.

Anyone who’s switched providers knows the difference: a few clicks can save hundreds per year.

Why don’t people just switch?

Behavioural economics has an answer here. Many customers stick with AGL out of status quo bias (it feels safer to stay with the known brand) and choice overload (too many plan options discourage switching). AGL also leans on authority and social proof: its long history, advertising presence, and millions of customers reassure households that it’s the “safe” option.

Can electricity brokers help?

Yes — especially for businesses and households overwhelmed by plan comparisons. Electricity brokers analyse usage, negotiate with retailers, and often secure cheaper rates than going direct. For companies with high energy spend, this can make a real dent in costs.

FAQ

Why is AGL closing coal plants if it makes electricity more expensive now?
Because regulators, investors, and the public are demanding cleaner energy. The upfront costs are painful, but long-term renewables are cheaper to run.

Are government subsidies making bills cheaper?
Some households receive rebates or bill relief, but these don’t always offset the structural cost increases in generation and networks.

Is loyalty ever rewarded by AGL?
Rarely. In fact, “loyal” customers often pay more because they don’t chase new-customer discounts.

At the end of the day, AGL’s high costs reflect both market forces and strategic choices. The good news? Households and businesses have options. Many are exploring comparison tools or even leaning on electricity brokers to cut through the noise and secure fairer deals.
