Alinta Energy: ownership, plans and where it sells

Alinta Energy at a glance

Figures are from the Australian Energy Regulator and Alinta's own announcements.

Who owns Alinta Energy?

Singapore's Sembcorp Industries owns 100% of Alinta Energy, having completed its acquisition on 11 June 2026. Hong Kong's Chow Tai Fook Enterprises owned Alinta from 2017 until then. Alinta says it continues to trade under its own brand and management. A change of owner does not change existing customers' contracts, which continue on their terms.

Alinta Energy rates by network, 2026-27

On 10 October 2026, Alinta Energy's lowest-priced single-rate electricity plan charged from 20.77 c/kWh to 41.91 c/kWh plus a daily supply charge, depending on the network zone, which put it anywhere from level with the reference price to 20% below it at standard usage. The reference price is the Default Market Offer (DMO), or the Victorian Default Offer (VDO) in Victoria.

Alinta's single-rate plans differ by state: HomeDeal Smart in NSW, HomeDeal Flow in south-east Queensland and SA, and HomeDeal Next in Victoria. In SA its lowest single-rate plan was level with the DMO; its demand-tariff plans there, which need a smart meter and charge for your peak demand, are priced differently and are not in the table.

Single-rate plans are the like-for-like comparison the regulators use. Time-of-use, controlled load and solar plans are priced differently, so run your own usage through Energy Made Easy or Victorian Energy Compare before you choose.

Where Alinta sells, state by state

On the east coast Alinta sells electricity and gas in NSW, Victoria, south-east Queensland and SA; in WA it sells gas:

Alinta in Western Australia

In WA, households cannot choose their electricity retailer on Western Power's network, but every gas customer can choose a gas retailer. Alinta had 422,474 residential gas customers in WA at 30 June 2025, the most of any WA gas retailer, according to the Economic Regulation Authority. If you are in Perth or the South West, gas is where comparing retailers can save you money; our WA electricity and gas page lists the other gas retailers and the regulated maximum prices.

Alinta's WA gas offers are discounts off its standard residential gas price. On 10 October 2026 its Fair Go 40 offer took 40% off the usage charges for one year for customers in the Coastal (Metropolitan) region, from Geraldton to Busselton, with a $100 credit for new and moving customers, and its Fair Go 46 offer took 46% off for WA Seniors Card members. The supply and account servicing charges are not discounted.

Regulator actions

In November 2025 Alinta paid $1,089,000 across a record 15 AER infringement notices for allegedly overcharging customers who paid through Centrepay and failing to notify and refund them within the required time. The AER said the conduct affected electricity and gas customers in NSW, Queensland and SA between April 2019 and September 2024.

Alinta's complaints record

The Australian Energy Regulator publishes how many complaints each retailer receives. The figures below are complaints made to Alinta itself by residential customers in NSW, Queensland, South Australia, Tasmania and the ACT, as reported to the AER, with the figure for all retailers beside them. We publish the counts and do not rate retailers.

In WA, which the AER's figures do not cover, Alinta reported 2,199 residential gas complaints to the Economic Regulation Authority in the year to 30 June 2025, from 422,474 residential gas customers.

Concessions and seniors

State energy concessions and rebates are paid by governments, so eligible seniors and other card holders keep them whichever retailer they choose. They do not move automatically when you switch: tell Alinta or your new retailer about your card, or in South Australia tell ConcessionsSA. Our state pages list each concession, for example in NSW, Victoria and Queensland.

Alinta Energy compared with AGL and Origin Energy

The public record for the three, side by side. For prices, the rates table above shows Alinta Energy's lowest single-rate plan in each zone, AGL vs Origin vs EnergyAustralia compares the big three zone by zone, and the government comparators show every plan at your address.

How to check Alinta's plans against the market

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 Alinta'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.
