AGL is one of Australia's three largest energy retailers and one of its oldest companies. It is listed on the ASX, dates back to 1837, and says it provides around 4.6 million energy and telecommunications services. It sells electricity and gas to households in NSW, Victoria, south-east Queensland, South Australia and the ACT, owns OVO Energy Australia, and is a joint venture partner in ActewAGL in Canberra.
This page sets out what the public record shows about AGL: its size in the regulator's figures, the types of plans it markets, and regulator actions. It does not rate AGL. Whether an AGL plan is good value for you depends on your network zone and usage, and the government comparators show every AGL plan alongside everyone else's.

| Ownership | AGL Energy Limited, listed on the ASX |
| Founded | 1837 (as the Australian Gas Light Company) |
| Sells to households in | NSW, Victoria, Queensland (south-east), SA, ACT |
| Fuels | Electricity and gas |
| Residential electricity customers (NECF states, 30 June 2025) | 1,486,942 (21.3% share) |

The AER groups AGL, Origin Energy and EnergyAustralia as Tier 1 retailers. Together they served 60.9% of residential electricity customers in the national-rules states at 30 June 2025, a share that has been falling slowly as smaller retailers grow. In gas, AGL is the largest retailer in those states by residential customers.
AGL sells standard flat-rate and time-of-use plans, solar plans, and an electric vehicle plan with cheaper overnight charging (the AER cites AGL's Night Saver EV plan as an example of EV-specific offers). Since 1 July 2026 it must also offer the Solar Sharer plan, with free midday power, in NSW, south-east Queensland and SA. Plan names and prices change often; the fact sheet on Energy Made Easy or Victorian Energy Compare is the reliable record.
In December 2024 the Federal Court ordered AGL to pay $25 million in penalties in proceedings brought by the AER over the handling of Centrepay payments from former customers. AGL appealed, and on 19 August 2026 the Full Federal Court allowed the appeal and set aside the findings and penalty (AGL Retail Energy Limited v Australian Energy Regulator [2026] FCAFC 106).
Retailers must publish their generally available plans to the government comparators: Energy Made Easy in NSW, Queensland, SA, Tasmania and the ACT, and Victorian Energy Compare in Victoria. Each plan there has a standard fact sheet listing every rate, fee and discount condition, which is the fairest way to line AGL's plans up against everyone else's.
Start with how far below the reference price each plan is (the Default Market Offer in NSW, south-east Queensland and SA, or the Victorian Default Offer), then run your own annual usage from a recent bill through the shortlist. The same retailer can be among the cheapest in one network zone and not in another.

Neither is better for everyone. Both sell many plans at different prices in each network zone. Compare the specific plans available at your address against the reference price and your own usage.
Yes. The AER notes that OVO Energy was acquired by AGL Energy Limited in April 2024. OVO continues to sell under its own brand.
