Searching for the cheapest electricity in NSW is understandable, but there is a catch: the cheapest plan depends on your location (network area), how you use electricity (single rate, time of use, demand), and the contract terms (benefit period, fees, discounts). This guide explains how to compare NSW electricity offers properly, what rules and benchmarks apply, and how Zembl can help you move to a better deal with less admin.
Important: Zembl does not represent every retailer in the market. Offers and availability vary by postcode, meter type, and connection. We can still help you benchmark your current plan against a panel of trusted retailers.
What does “cheapest electricity” mean in NSW?
Most people mean one of these:
- Lowest estimated annual cost for their usage
- Lowest usage rate (c/kWh)
- Lowest daily supply charge (c/day)
- Best value after discounts and fees are included
The best way to compare is to focus on the estimated annual cost for your household or small business, using your actual consumption and meter data where possible. A plan with a low usage rate can still be expensive if the supply charge is high, or if peak rates apply when you use most power.
NSW electricity is not one market, it depends on your network area
In NSW, retail competition is available for most households and small businesses, but your bill is strongly affected by the local distribution network (the poles and wires). Most premises fall into one of these network areas:
- Ausgrid: much of Sydney, Central Coast and Hunter
- Endeavour Energy: Greater Western Sydney, Blue Mountains, Illawarra and Southern Highlands
- Essential Energy: regional and rural NSW
Network charges and tariff structures differ by network. That is why a plan that looks cheapest for a Sydney postcode might not be cheapest in regional NSW.
How electricity pricing works in NSW
Your electricity price is made up of multiple components. Understanding these helps you compare like for like:
- Wholesale energy costs: influenced by supply, demand, weather, outages, and fuel prices in the National Electricity Market (NEM).
- Network charges: set or approved by regulators and vary by network area and tariff.
- Environmental scheme costs: such as renewable scheme costs that are passed through.
- Retail costs and margin: billing, call centres, payment fees, and retailer margin.
The Default Market Offer (DMO) explained for NSW
The Default Market Offer is the regulated benchmark for standing offers in NSW (and some other NEM states). Retailers also use it as the reference price when advertising discounts, for example “X% less than the reference price”.
Practical takeaway: when you compare plans, check both:
- the percentage difference vs the reference price (DMO), and
- the estimated annual cost for your usage and tariff.
A plan that is “20% less than the reference price” may still not be cheapest for you if you are on a different tariff type or if fees erode the savings.
Common tariff types in NSW and why they matter
Two customers on the same retailer and postcode can pay very different bills because they are on different tariffs.
Single rate (flat rate)
You pay one usage rate at any time of day. This can suit many households with steady usage.
Time of use (TOU)
You pay different rates for peak, shoulder and off peak periods. TOU can be cheaper if you can shift usage to off peak times, but expensive if most usage happens during peak.
Demand tariffs
Some small businesses and larger sites have a demand component based on the highest demand recorded during the billing period. Demand charges can dominate your bill if you have short bursts of high load (for example, multiple compressors or HVAC starting at once).
Controlled load
Some properties have separately metered appliances (often hot water systems) that can be billed at a different rate.
How to compare electricity plans in NSW step by step
- Grab a recent bill: ideally 3 to 12 months, especially if your usage is seasonal.
- Identify your network area: Ausgrid, Endeavour, or Essential Energy.
- Check your meter type: basic or smart/interval meter. This affects eligibility for TOU plans.
- Confirm your current tariff: single rate, TOU, demand, controlled load.
- Compare estimated annual cost: not just the headline c/kWh rate.
- Review fees and terms: benefit period, exit fees, late fees, pay on time discounts and whether they are conditional.
- Start early: begin comparing at least 6 to 12 weeks before your contract ends to avoid rolling onto higher rates.
Ways to reduce your NSW electricity bill beyond switching
- Fix tariff mismatches: a TOU plan may be wrong if most usage is during peak.
- Reduce demand peaks (small business): stagger equipment start up, review HVAC settings and maintenance.
- Check for billing errors: incorrect meter reads or incorrect tariff assignment can happen.
- Improve efficiency: LED lighting, better controls, and equipment upgrades often deliver recurring savings.

Frequently asked questions
Who is the cheapest electricity provider in NSW right now?
It depends on your postcode, network area, meter type and usage profile. The cheapest plan for one household can be expensive for another. Comparing estimated annual cost using your bill data is the most reliable approach.
Is it safe to switch electricity providers in NSW?
Yes. Your electricity supply does not stop when you switch retailers. The network continues to deliver power, and the change is mainly billing and contract administration.
How often should I compare electricity plans?
As a rule of thumb, review your plan at least once per year, and always start comparing several weeks before your contract ends.
Do small businesses in NSW have access to the same plans as households?
Some plans are available to both, but many retailers offer separate small business products, and demand tariffs may apply depending on your meter and usage.
