The largest energy companies in NSW

Fact Checked Fact Checked

A report by Australia’s energy regulator has revealed that households in New South Wales are the most likely to stick with the ‘big three’ power companies, despite a number of new providers entering the fray to take the total number available in the Sydney area to 20+.

Almost 80 per cent of residential customers across NSW are still connected with either Origin, AGL or EnergyAustralia, way above the number in Victoria (54.09%), south-east Queensland (50.7%) and South Australia (72.2%), the report found.

With this in mind, we explore which electricity and gas providers are the biggest in terms of market share in NSW, as well as helpful information about how to find a good deal.

How many NSW customers are on market offers?

Hand with best offer concept

According to the Australian Energy Regulator (AER), 90.3 per cent of electricity customers in New South Wales are currently on a market contract. While it’s encouraging to see more NSW residents actively pursuing the best offers in their area, there are still about one in ten who are likely on a less competitive plan.

Who are the biggest gas suppliers in NSW?

It’s a similar story for natural gas in NSW, with the residential market dominated again by the big three. This time though, it’s AGL out on top with 40.7 per cent of residential customers, EnergyAustralia with 25 per cent and Origin Energy with 19.8 per cent of the market. Following behind these gas suppliers are Red Energy (5.6%), Alinta Energy (2.9%) and Simply Energy (2.1%).

What about small business energy in NSW?

Unsurprisingly, Origin is the largest small business energy provider in NSW, claiming 32.2 per cent of the electricity market and 50.9 per cent for natural gas. AGL and EnergyAustralia are the next biggest, also holding substantial amounts of the small business electricity and gas markets.

Is bigger better in NSW?

With a clear majority of New South Welshmen and women remaining loyal to the big guys, is it a simple case of bigger is better? For many customers, Origin, AGL and EnergyAustralia may offer a safe bet, but for others less likely to gravitate towards a recognisable brand, there could be more suitable deals out there from companies you’ve never heard of.

The big providers can certainly do you a good deal, as long as you’re on one of their cheapest market offers. However, it’s rare to find the big three represented when it comes to the absolute cheapest prices around. That said, you may be willing to spend a little more for the apparent comfort of going with a well-known name

Regardless of which energy provider you choose, remember that the electricity and natural gas in your area comes from the same distribution network. This means that your energy supply will not be compromised if you go with a smaller company. You may, however, find a difference in the level of service provided or other value-add incentives, like bill credits and discounts. This is where our free comparison tool below can help.
