Electricity procurement can be challenging for Australian businesses because wholesale and forward electricity prices can change significantly over time. A business that locks in its entire electricity requirement on one day may secure certainty, but it also becomes heavily dependent on market conditions at that particular moment.
Progressive purchasing energy offers a different approach. Instead of fixing all future electricity requirements at once, a business purchases portions of its expected consumption at different times. These transactions create a blended electricity price and reduce reliance on a single market entry point.
This strategy does not guarantee the lowest possible energy price. Instead, it helps businesses manage timing risk, maintain greater purchasing flexibility and develop a more structured approach to electricity procurement.
Progressive purchasing energy is a procurement strategy where a business secures its future electricity requirements in several stages rather than through one transaction.
For example, instead of purchasing 100 per cent of expected electricity requirements for a future year at one time, a business may secure portions of that requirement over several months.
Each transaction reflects the forward electricity price available at that time. As a result, the business eventually receives a blended procurement price based on multiple purchasing decisions.
This approach contrasts with conventional fixed-price contracting, where most or all of the required electricity is secured at one point.
Although electricity contracts vary between retailers and customers, progressive purchasing generally follows several key stages.
Businesses first need to understand how much electricity they currently use and how much they are likely to need in the future.
Important considerations include:
Accurate consumption data helps businesses estimate future requirements and avoid purchasing inappropriate volumes.
A progressive purchasing strategy should establish clear rules before market transactions begin.
The framework may define how much electricity can be purchased at each stage, who has authority to approve transactions, acceptable budget limits and the maximum amount of future electricity that can remain exposed to market prices.
A structured process helps prevent procurement decisions from becoming emotional or speculative.
Businesses then monitor the forward electricity market.
Prices can move because of changes in electricity supply and demand, generation availability, weather, fuel costs, transmission conditions and regulatory developments.
However, progressive purchasing should not become an attempt to predict every market movement. Market monitoring should support an agreed risk-management strategy.
The business progressively secures portions, commonly called tranches, of its future electricity needs.
For example, an organisation could purchase several portions of its future requirement throughout the procurement window.
Some purchases may occur when forward prices are comparatively low, while others may occur at higher levels.
Once several purchases are completed, the organisation effectively creates a blended electricity procurement position.
This reduces the influence that one unusually high market day can have on the entire contract.
Businesses should understand the differences between progressive purchasing and traditional fixed-price contracts.
| Factor | Progressive purchasing | Fixed-price contract |
| Purchasing timing | Several transactions | Usually one major decision |
| Price outcome | Blended across purchases | Based largely on one contracting period |
| Market exposure | Reduces progressively | Usually reduced immediately |
| Budget certainty | Develops over time | Established earlier |
| Flexibility | Higher | Lower after fixing |
| Market monitoring | Regular monitoring required | Limited after contracting |
| Management complexity | Higher | Lower |
| Timing risk | Spread across multiple purchases | Concentrated around one purchase |
Neither approach is automatically better. Businesses should choose a strategy based on their risk tolerance, electricity usage, budget requirements and procurement capabilities.
One of the main advantages of progressive purchasing is that businesses do not depend entirely on one contracting date.
If a company locks in all electricity when forward prices are unusually high, it may remain committed to those prices throughout the contract period.
Progressive purchasing spreads this timing exposure across several transactions.
Because electricity is secured progressively, businesses can respond to changing market conditions.
If forward prices decline while part of the requirement remains open, the organisation may have an opportunity to secure additional electricity at lower prices.
However, businesses must also recognise that prices can rise.
Progressive purchasing generally requires businesses to develop clearer procurement rules.
The organisation may establish:
This structure can turn electricity procurement into an ongoing risk-management process rather than a last-minute contract renewal exercise.
Businesses have different levels of tolerance for electricity price volatility.
A company focused heavily on budget certainty may secure larger portions earlier. Another organisation may keep a greater proportion open to retain market flexibility.
Progressive purchasing can therefore be adjusted to suit different procurement objectives.
Progressive purchasing offers flexibility, but businesses must understand its risks.
The biggest risk is that electricity prices increase while substantial volumes remain unpurchased.
Electricity already secured remains protected at the agreed price, but the remaining requirement may become more expensive.
Therefore, continuously waiting for lower prices can increase risk.
Progressive purchasing usually requires more active management than a conventional fixed-price contract.
Businesses need people or advisers who can:
Without effective governance, the strategy can become difficult to manage.
Future electricity consumption may differ from forecasts.
Expansion can increase usage, while site closures, efficiency upgrades or solar installations can reduce grid consumption.
Businesses should regularly review forecasts and understand how their contract deals with changes in demand.
Progressive purchasing is generally most relevant to larger electricity consumers that have enough scale and internal capability to manage an active procurement strategy.
Potential users include:
However, size alone does not determine suitability.
Businesses should also have reliable energy data, reasonable visibility over future consumption, clear budget goals, defined risk tolerance and appropriate decision-making processes.
Companies that prioritise simplicity and immediate budget certainty may prefer a conventional fixed-price contract.
The first step is reviewing historical and expected electricity consumption.
Businesses should understand when electricity is used, how demand changes throughout the year and whether future operations could significantly alter consumption.
Better data supports more accurate purchasing decisions.
Businesses need to determine what they want their procurement strategy to achieve.
Objectives may include:
These priorities may sometimes compete. Greater certainty often requires securing more electricity earlier, while greater flexibility means maintaining more market exposure.
Businesses can establish rules that determine when additional electricity should be secured.
Triggers might include:
These triggers help keep decisions consistent.
A business should not rely only on preferred price targets because the market may never reach them.
Instead, organisations can require certain percentages of future demand to be secured by predetermined dates.
This helps reduce the risk of reaching the supply period with too much electricity still exposed.
Electricity prices can change quickly, so businesses need clear internal authority.
Everyone involved should understand who monitors prices, who recommends a purchase and who has final approval.
Efficient governance can improve execution and reduce unnecessary delays.
Progressive purchasing can form part of a broader energy strategy.
Australian businesses may combine electricity procurement with:
A Power Purchase Agreement, for example, may provide long-term renewable electricity pricing, while progressive purchasing can help manage other parts of an organisation's energy requirement.
Therefore, businesses should consider procurement, sustainability and energy efficiency together rather than treating them as separate issues.
One common mistake is trying to identify the absolute lowest point in the electricity market. Consistently predicting market bottoms is extremely difficult, so progressive purchasing should focus on managing risk rather than market speculation.
Another mistake is operating without a written procurement framework. Purchasing decisions should follow agreed rules instead of being driven by short-term market sentiment.
Businesses should also avoid leaving too much electricity unpurchased as the supply period approaches. A progressive strategy requires enough time to make multiple purchasing decisions effectively.
Finally, businesses should consider total electricity costs rather than focusing only on wholesale electricity prices. Network charges, environmental costs, metering and retailer charges may also influence the final bill.
Before choosing progressive purchasing, businesses should consider several questions.
| Question | Why it matters |
| Is our electricity usage predictable? | Reliable forecasts support better purchasing decisions |
| How much market volatility can we tolerate? | Determines acceptable open exposure |
| Do we require early budget certainty? | May favour faster purchasing |
| Do we have sufficient electricity volume? | Some products may have minimum requirements |
| Who can approve transactions? | Clear authority supports fast decisions |
| Can we monitor the market regularly? | Progressive purchasing requires active management |
| What happens if prices rise sharply? | Tests the organisation's risk controls |
| Will our electricity requirements change? | Determines necessary contract flexibility |
A structured assessment helps businesses determine whether progressive purchasing provides useful flexibility or unnecessary complexity.
Progressive purchasing energy allows Australian businesses to secure electricity in stages rather than committing their entire future requirement at one market price.
By purchasing electricity across several periods, businesses can spread timing risk, develop a blended procurement price and maintain some flexibility as market conditions change. However, progressive purchasing does not guarantee lower electricity costs. Remaining volumes can become more expensive when markets rise and the strategy requires reliable data, clear governance and ongoing monitoring.
For businesses considering progressive purchasing, Energy Action can help evaluate procurement options, monitor market conditions and establish electricity purchasing strategies aligned with financial and operational goals.
Energy Action's energy procurement expertise can help Australian businesses manage electricity costs more strategically while maintaining appropriate levels of risk and flexibility.
Progressive purchasing energy is a procurement strategy where businesses secure portions of their future electricity requirements at different times rather than buying everything at once. Each transaction contributes to a blended electricity price. The strategy primarily aims to spread market timing risk across several purchasing decisions.
Not necessarily. Progressive purchasing may benefit a business if forward electricity prices decline while some requirements remain unpurchased, but the opposite can happen if prices rise. Its primary advantage is managing timing risk rather than guaranteeing the lowest electricity price.
Progressive purchasing generally suits larger electricity consumers with reliable consumption data and appropriate procurement governance. These businesses should also have the financial capacity to tolerate some market exposure while future requirements remain open. Organisations requiring maximum simplicity may prefer a fixed-price contract.
The main risk is that electricity prices rise while part of the future requirement remains unsecured. Businesses may also face risks from inaccurate consumption forecasts, delayed decisions and inadequate internal governance. Purchasing limits, deadlines and defined approval processes can help manage these risks.
Businesses should begin by analysing historical electricity consumption and forecasting future requirements. They should then establish procurement objectives, risk limits, purchasing triggers and internal approval responsibilities. Professional energy procurement advice can also help businesses assess available contract structures and implement a suitable strategy.
