How Can Businesses Reduce Peak Demand Charges?

The energy consumption cost of most industrial and commercial establishments is determined not only by the total quantity of energy consumed but also by the time period of its consumption. It is important to understand how one can reduce peak demand charges. Companies taking a proactive approach to peak demand management can achieve substantial energy savings while boosting energy resilience.

Why Peak Demand Costs So Much

Utility companies structure rates taking into account how difficult it would be to serve sudden and big demand from customers. As soon as an organisation reaches its highest point of demand (usually recorded within a time interval of 15 or 30 minutes), it determines the bill for that time. It is called "spike" and might entail high peak demand cost, even if the energy demand is low.

There is one more reason for organizations to understand kW and kVA demand. In most instances, they are not being billed for real but apparent power. Thus, it is important to have a good power factor.

Strategy 1: Identify Your Peak with Interval Data

Visibility is the first step in an effective demand reduction strategies business plan. Interval data, which is collected during shorter intervals of time, will show the precise time and the reason behind the spikes. Through analysing the interval data, companies will be able to identify what causes spikes.

Agile Energy will assist companies in understanding the data so that it can be used to devise specific strategies.

Strategy 2: Stagger Equipment Start-Up

The simultaneous startup of heavy equipment will generate an unnecessary increase in demand. The scheduling of the startup of the equipment, compressors, or refrigeration units can greatly help decrease the peak load.

This is a simple strategy that costs very little but will immediately lower the demand charge.

Strategy 3: Load Shifting to Off-Peak

Load shifting is defined as a method of rescheduling energy-intensive activity during a period of low demand. This includes operating manufacturing equipment at night and planning energy-intensive processes out of peak times.

This method is central to demand management Australia through the use of time-of-use pricing.

Strategy 4: Battery Peak Shaving

The battery storage systems are now being adopted for peak load shaving, since the stored energy is released during peak hours in order to minimise the dependence on the electricity grid. In this way, companies need not depend on the grid for taking the maximum possible power.

This approach works effectively along with the renewable energy system while forming part of broader battery and asset-backed solar solutions.

Strategy 5: Solar Aligned to Demand Windows

With the installation of solar panels for commercial buildings, businesses can reduce the peak demand during the day, particularly where there is a coincidence between peak demand and times of solar generation. Many businesses in areas such as Western Australia consider commercial solar energy Perth to cater for their high daytime demand through solar energy.

Similarly, the purpose of commercial solar installation Brisbane is to generate as much solar energy as possible during their peak hours of operation in order to reduce their dependency on grid power during the peak hours.

Some other organisations use power purchase agreements, enabling them to generate solar energy without investing any money but enjoying reductions in their demand. The use of a ground-based system like the ground mount solar installation is another option that could help increase generation capacity.

Strategy 6: Power Factor Correction

Power factor being low means that the apparent power will be high, hence higher costs. Correction devices are installed for lower kVA chargers with an improvement in the efficiency of electrical systems.

The most beneficial aspect of using correction devices is in installations having significant inductive load, for instance, factories or large HVAC units.

Strategy 7: Demand Response Participation

Companies that take part in the demand response schemes benefit from reduced energy consumption by being rewarded with incentives for their efforts.

Such schemes are a good component of contemporary energy policies and correspond with sustainable development principles.

Strategy 8: HVAC and Process Optimisation

HVAC systems are frequently important sources of peak demand. Scheduling for optimal HVAC usage, installing energy-efficient HVAC equipment, and using control strategies will help minimise peak demand.

The same applies for industrial energy use, where minimising high loads at the same time improves performance.

Strategy 9: Right-Sizing Your Network Tariff

Most organisations still operate under tariffs that do not match their consumption patterns. Revising tariffs to make them match the operational requirements of a company is therefore necessary.

Energy advisors like Agile Energy usually come in handy when it comes to helping organisations get more aligned tariffs.

Building a Demand-Reduction Business Case

Reducing demand charges entails decisions on operations and capital investments. An effective business case should involve:

• Historical demand analysis
• Identification of peak causes
• Evaluation of the cost and benefits for each technique
• The payback period and ROI

An integrated application of various techniques like solar, battery, and operations management usually provides the best outcome. Firms which consider an integrated perspective for demand charges business electricity can make both immediate and long-term gains.
