First of all, what is demand charge management?
Demand charge management is a critical aspect of energy management that has become increasingly important for businesses in Australia. Demand charges are fees electricity providers charge businesses based on the highest peak demand a business generates during a specific time frame. These charges are designed to cover the costs of maintaining and upgrading the electricity grid during peak periods when energy usage is at its highest.
Demand charge management is important for businesses because demand charges can account for a significant portion of their electricity bill, particularly for businesses with high energy consumption levels. By actively managing energy consumption to reduce peak demand, businesses can significantly reduce their energy bills and improve their bottom line.
In addition to the financial benefits, demand charge management also helps to reduce strain on the electricity grid, which can help to prevent blackouts and reduce the need for expensive upgrades to the grid infrastructure.
Demand charge management involves actively managing how energy is consumed to reduce peak demand and thus reduce demand charges. This can involve a range of strategies, including load shifting, energy efficiency measures, and demand response programs.
Load shifting
Load shifting shifts energy consumption from peak to off-peak periods when energy is cheaper. For example, a business might run energy-intensive processes, such as manufacturing or refrigeration, during the night when energy demand is lower.
Energy efficiency measures
Energy efficiency measures involve improving the energy efficiency of buildings and equipment, reducing the overall energy consumption of a business. This can include upgrading lighting to LED, installing energy-efficient appliances, and improving insulation.
Demand response programs
Demand response programs encourage businesses to adjust their energy consumption during peak demand periods, which can help to avoid blackouts and reduce the overall cost of electricity.
Demand response programs involve temporarily reducing energy consumption during periods of peak demand in order to reduce strain on the electricity grid. This can involve shutting down non-essential equipment, dimming lights, and adjusting air conditioning systems.
How businesses can participate in demand response programs
Participating in a demand response program is a great way for businesses to manage their demand charges and earn incentives from utilities. Here are the steps businesses can take to participate in demand response programs:
Businesses can start by finding a demand response provider that offers services in their area. These providers work with utilities to offer demand response programs to businesses. They can help businesses to understand the program requirements and the incentives available.
To participate in a demand response program, businesses must first understand their energy use. This means identifying the appliances and processes that use the most energy and when they are typically used.
Once businesses understand their energy use, they can start identifying energy reduction opportunities. This could involve adjusting the timing of certain processes or replacing inefficient appliances with more energy-efficient models.
Businesses should develop an energy reduction plan that outlines the steps they will take to reduce their energy use during peak demand periods. This plan should include specific targets and timelines.
Once businesses have a plan in place, they can sign up for a demand response program. These programs typically involve businesses agreeing to reduce their energy use during peak demand periods in exchange for incentives from utilities.
Benefits of Demand Response Programs
Participating in demand response programs can provide businesses with several benefits, including:
Businesses can reduce their energy costs by avoiding peak demand charges by participating in a demand response program.
Demand response programs offer incentives to businesses to reduce their energy use during peak demand periods, which can provide additional revenue streams.
Participating in a demand response program can help businesses identify opportunities to improve their energy efficiency and reduce their overall energy use.
Demand response programs are an effective way for businesses to manage their energy costs and earn incentives from utilities. By understanding their energy use, identifying opportunities for energy reduction, and signing up for a demand response program, businesses can benefit from reduced energy costs, additional revenue, and improved energy efficiency.
Common misconceptions about demand charge management
Misconception #1: Demand charge management is only relevant to large commercial and industrial customers
One of the most common misconceptions about demand charge management is that it is only relevant to large commercial and industrial customers. While it is true that these customers are typically the largest users of electricity and, therefore, have the most to gain from demand charge management, smaller businesses and households can also benefit from managing their demand charges.
Demand charges are typically applied to all customers, regardless of size. They are designed to reflect the cost of supplying electricity at times of peak demand and therefore impact all customers who consume energy during these periods. By managing their demand charges, businesses and households can reduce their electricity bills and help to alleviate pressure on the electricity grid.
Misconception #2: Demand charge management requires complex technology and expertise
Another common misconception about demand charge management is that it requires complex technology and expertise. While there are advanced technologies and systems available for demand charge management, it is not necessary for businesses and households to invest in these to see benefits.
Simple measures such as implementing energy-efficient practices, shifting non-essential energy use to off-peak periods, and using energy storage solutions can help to reduce demand charges. In addition, many electricity retailers offer demand response programs that allow customers to reduce their electricity use during times of peak demand and earn financial incentives.
Misconception #3: Demand charge management is only effective for businesses and households with consistent energy usage patterns
Another misconception about demand charge management is that it is only effective for businesses and households with consistent energy usage patterns. While it is true that businesses and households with more predictable energy usage patterns may find it easier to manage their demand charges, it is still possible for those with less predictable energy usage to benefit from demand charge management.
Technologies such as energy storage solutions and demand response programs can help to mitigate the impact of unpredictable energy usage patterns on demand charges. In addition, electricity retailers often offer flexible pricing plans that allow customers to pay lower rates during off-peak periods, which can help to reduce demand charges for those with less predictable energy usage.
Misconception #4: Demand charge management is only relevant in areas with high electricity prices
Finally, some people believe demand charge management is only relevant in areas with high electricity prices. While it is true that demand charges may be more significant in areas with high electricity prices, they are still applied in all regions of Australia.
By managing their demand charges, businesses and households in any area of Australia can reduce their electricity bills and help to alleviate pressure on the electricity grid. Furthermore, as electricity prices continue to rise across the country, demand charge management will become increasingly important for all customers, regardless of location.
Demand charge management is a valuable tool for businesses and households in Australia to reduce their energy bills and help to alleviate pressure on the electricity grid. However, several misconceptions about demand charge management can hinder its adoption and effectiveness. By understanding the truths behind these ideas, businesses and households can make informed decisions about managing their demand charges and reap the benefits of reduced electricity costs.
Spotlight on successful demand charge management
Based on the highest amount of electricity a business uses during peak periods, electricity demand charges can be a significant expense for commercial and industrial customers. Many businesses in Australia are searching for ways to reduce their demand charges, and some have succeeded. Below are a few success stories that explore how they achieved their goals.

Amcor, a global packaging company, reduced their demand charges at one of their plants in Australia. Amcor employed 3 MW of backup generation at their Gawler glass facility to supply demand-side response services in South Australia, utilising their preferred demand-side aggregator. The service provider aggregated different pieces of Amcor’s capacity into a dependable portfolio and contracts for demand-side response services with National Electricity Market players. The solar panels generate electricity during the day, which is used to power the plant, and any excess energy is stored in the battery for use during peak periods. By reducing their reliance on grid electricity during peak periods, Amcor was able to significantly reduce their demand charges.
Following imminent network capacity issues in the local area, a demand side aggregator approached Bankstown Sports Club. The club agreed to offer network support using on-site generation because it was plainly preferable to experiencing supply disruptions due to network outages.
The initial agreement was updated and extended to enable demand side aggregation despatch during periods of extremely high wholesale market spot pricing. The updated agreement’s terms and conditions are similar to the original agreement, and it requires the club to provide ‘standby’ and ‘despatch’ services (usually) during the hot summer months.
A remote, automatic start facility for the club’s diesel generators was installed and carefully validated by the demand side aggregator. This enabled the demand side aggregator to remotely despatch generators at very short notice (5 minutes) during extremely high spot price times. However, the club kept control over the generators, which may be ‘locked out’, blocking the remote start function, whenever required (e.g. for routine maintenance of the generating units or controllers).
