The difference between the wholesale vs retail electricity price can be confusing. You might see reports that wholesale electricity prices have fallen sharply and then wonder why your business electricity bill has not fallen by the same amount.
The reason is relatively simple: wholesale electricity is only one part of the total cost of supplying power to a business.
In Australia's National Electricity Market, electricity is traded through a wholesale spot market where generators supply electricity and prices change every five minutes. However, businesses generally purchase electricity from retailers rather than buying directly at the current spot price.
Consequently, the price on a retail electricity bill needs to recover wholesale energy costs alongside network charges, environmental obligations, retailer operating expenses and other costs. Retailers also manage the financial risk created by highly volatile wholesale prices.
Understanding this distinction can help businesses interpret market headlines correctly and make better energy procurement decisions.
The wholesale electricity price is essentially the market value of electricity before many of the costs required to deliver and retail that electricity to an end customer are added.
Within the National Electricity Market, generators offer electricity into a common pool. The Australian Energy Market Operator coordinates supply and demand, with generation scheduled at five-minute intervals. Queensland, New South Wales and the Australian Capital Territory, Victoria, South Australia and Tasmania participate in the NEM, while Western Australia and the Northern Territory operate outside it.
Wholesale prices can move rapidly because electricity supply and demand must remain balanced.
Prices may be influenced by:
As a result, the spot price at one moment does not represent the cost that a retailer will necessarily incur across a month, quarter or year.
For example, AEMO reported that the average NEM wholesale spot price during the first quarter of 2026 was $73/MWh. However, monthly averages ranged from $85/MWh in January to $64/MWh in March. This variation demonstrates why using one wholesale price as a direct comparison with a retail tariff can be misleading.
The easiest way to understand the wholesale vs retail electricity price is to think of wholesale electricity as an input into the finished retail product.
A retailer does not simply purchase electricity for a wholesale price and resell exactly the same product for a small markup. Instead, the retailer provides a bundled service that incorporates electricity purchasing, network delivery and other regulated and commercial costs.
| Cost component | What it covers |
| Wholesale electricity | Purchasing electricity and managing wholesale market exposure |
| Network charges | Transmission and distribution of electricity |
| Environmental costs | Renewable and environmental scheme obligations |
| Metering and market costs | Metering and electricity market services |
| Retail operating costs | Billing, customer service, systems and administration |
| Risk management | Managing exposure to volatile wholesale electricity prices |
| Retail margin | Commercial return for the retailer |
The Australian Energy Regulator uses a similar cost build-up when determining the Default Market Offer, considering wholesale electricity, network, environmental and retail costs before applying a retail margin.
Therefore, even if wholesale electricity became extremely inexpensive during a particular period, the other components of your retail price would not simply disappear.
One of the most important points in the wholesale vs retail electricity price discussion is timing.
Businesses often expect a reduction in wholesale prices to appear almost immediately in retail contracts. In practice, there can be a substantial delay.
The AER specifically notes that movements in wholesale markets do not flow through to household and small business bills immediately or dollar-for-dollar.
Retailers need to protect themselves and their customers against volatile spot prices. Therefore, they commonly use financial hedging arrangements that lock in wholesale prices ahead of delivery.
This approach enables retailers to offer customers more predictable prices even though the underlying wholesale market can move dramatically.
The same principle is relevant to business energy procurement. Forward electricity contracting can give businesses greater price certainty and reduce exposure to sudden market changes.
However, hedging also means today's retail rate may partly reflect wholesale market expectations and contracts established months or even years earlier.
Consequently, a wholesale market decline today does not necessarily mean your retailer is immediately purchasing all of your electricity at that lower price.
Wholesale electricity remains important, but it is not the whole bill.
The AER reported that wholesale costs represented approximately 33 to 41 per cent of Default Market Offer prices for residential customers in 2025–26. Retail operating costs represented around 11 to 16 per cent for residential customers and 6 to 9 per cent for small businesses, while environmental costs contributed approximately 3 to 4 per cent.
Although the precise proportions vary by customer, region, tariff and year, the figures illustrate the broader point: wholesale electricity is only one component.
Electricity must travel from generators through transmission and distribution infrastructure before reaching most business sites.
Network charges help recover the cost of building, operating and maintaining that infrastructure. Importantly, these charges can move differently from wholesale prices.
For example, the AER stated that 2026–27 network charges were mostly increasing across the regions it regulates, driven by factors including transmission costs, inflation and regulated revenue paths. Those network charges are subsequently incorporated into retail electricity prices.
Therefore, lower wholesale costs can occur at the same time as higher costs elsewhere in the electricity supply chain.
The gap between wholesale and retail prices also reflects risk.
Imagine a retailer promising a business a relatively stable rate while having to purchase all of its electricity at the constantly changing five-minute spot price. A period of extreme wholesale prices could expose that retailer to substantial financial losses.
Instead, retailers typically manage their exposure through hedging contracts, generation ownership and other risk-management strategies. The AER explains that hedging can lock in future wholesale prices and help retailers provide more stable prices to customers.
This stability has value.
A business may prefer a known electricity rate because it supports budgeting and financial planning. Therefore, comparing a stable contracted retail rate against a particularly low five-minute or daily wholesale price does not provide an equivalent comparison.
Some large electricity users can adopt arrangements that provide greater exposure to wholesale market pricing. However, wholesale exposure comes with additional complexity and risk.
When wholesale prices are low, an exposed customer can potentially benefit. Conversely, periods of very high spot prices can quickly increase electricity costs.
For many businesses, the objective is therefore not simply to find the lowest visible electricity price. Instead, an effective procurement strategy balances:
Businesses can also consider fixed-rate, variable-rate, hybrid and Power Purchase Agreement structures depending on their objectives.
Understanding the wholesale vs retail electricity price helps businesses avoid making procurement decisions based on misleading comparisons.
Rather than asking, "Why can't I pay today's wholesale price?", businesses should consider what their total electricity arrangement costs and what risks the contract transfers or retains.
A commercial electricity contract can contain several pricing components and conditions. Therefore, businesses should review demand charges, network costs, contract duration, termination provisions and other applicable fees alongside the energy rate.
Consumption patterns also matter. A business operating mainly during periods of high demand may have a different risk profile from a site that can shift substantial consumption into lower-cost periods.
Historical energy data can consequently provide valuable information when assessing contract options. Understanding when and how much electricity a business consumes can also strengthen procurement decisions.
Consider a simplified example.
Suppose a news report says wholesale electricity averaged $80/MWh. That equals 8 cents per kWh for the wholesale energy component alone.
It does not mean a business should expect an 8-cent-per-kWh retail tariff.
The retailer may still need to recover network charges, environmental obligations, market and metering costs, operating expenses and the cost of managing wholesale risk. In addition, the retailer's actual hedged wholesale cost may differ significantly from the current spot market average.
Therefore:
Wholesale market price + supply-chain costs + risk management + retail costs and margin = retail electricity price
This simplified equation explains why comparing a wholesale market headline directly with the rate on an electricity bill rarely provides the full picture.
Wholesale prices still matter.
Persistent changes in wholesale electricity costs can eventually influence retail contract pricing. Indeed, the AER's 2026–27 Default Market Offer methodology explicitly incorporates wholesale costs alongside network, environmental and retail costs.
However, the timing and size of that impact depend on several factors, particularly hedging conditions and changes in other cost components.
For businesses approaching contract renewal, wholesale and forward market conditions can provide useful context. Nevertheless, trying to select a contract solely by predicting the bottom of the market creates significant risk.
A structured procurement strategy considers market conditions alongside the organisation's budget, consumption profile, contract expiry date and tolerance for price volatility.
The wholesale vs retail electricity price difference exists because the wholesale spot market represents only one stage of Australia's electricity supply chain.
Wholesale prices can change every five minutes, while retail electricity prices incorporate wholesale procurement, network charges, environmental obligations, operating expenses, risk management and retail margins. Furthermore, retailers commonly hedge electricity purchases ahead of time, which means changes in wholesale markets do not necessarily reach business customers immediately.
For Australian businesses, understanding these differences makes it easier to evaluate electricity offers, interpret energy market movements and choose an appropriate procurement strategy.

Wholesale electricity prices represent the price of electricity traded in the wholesale market, while retail prices represent what an end customer pays under an electricity plan or contract. Retail prices incorporate additional costs such as network services, environmental obligations, retail operations and risk management. Therefore, the wholesale electricity price should not be treated as the final delivered cost of electricity.
Retail electricity prices do not necessarily follow wholesale spot prices immediately because retailers generally purchase and hedge electricity ahead of delivery. Furthermore, network, environmental, metering and retail costs can change independently of wholesale electricity prices. The AER has confirmed that wholesale movements do not flow through to retail bills immediately or dollar-for-dollar.
Within the National Electricity Market, electricity is dispatched and wholesale spot prices are determined at five-minute intervals. Consequently, spot prices can be substantially more volatile than the contracted electricity rates businesses usually see. Retail and forward contracts help manage this short-term volatility.
The final retail price can incorporate wholesale electricity procurement, transmission and distribution network costs, environmental scheme costs, metering, retailer operating expenses and margins. The exact composition varies according to region, customer type and electricity plan. For this reason, businesses should compare complete contract costs rather than focusing solely on wholesale market prices.
Yes, but the benefit may not appear immediately. Sustained reductions in wholesale and forward prices can influence future retail offers and contract renewal opportunities, although network and other cost movements also affect the final result. Businesses can therefore benefit from monitoring the market and reviewing procurement options before their existing electricity contract expires.
