Australian SMEs face predictable energy cost spikes during winter and summer months. While you can’t control the weather, you can control how your business responds to seasonal demand patterns. Smart planning and strategic adjustments help maintain stable energy costs year-round.
Energy demand follows predictable seasonal patterns across Australia. Winter heating and summer cooling create distinct usage spikes that directly impact your electricity bills. Peak demand periods typically occur between 4-8pm on weekdays when commercial and residential consumption overlap.
Highest electricity costs occur during peak demand hours when commercial and residential usage overlap
The National Electricity Market operates on supply and demand principles. When demand exceeds supply during peak periods, wholesale prices increase rapidly. These costs flow through to commercial customers, particularly those on time-of-use tariffs or market-linked contracts.
Commercial heating accounts for up to 40% of winter energy consumption in Australian businesses. Start by servicing heating systems before the cold months arrive. Clean filters, check ductwork for leaks, and calibrate thermostats to ensure optimal performance.
Set heating temperatures between 18-20°C during business hours. Each degree above 20°C can increase heating costs by up to 10%. Use programmable thermostats to reduce temperatures automatically outside business hours and in unoccupied areas.
Consider zone heating for larger premises. Heat only the areas your staff and customers actively use rather than maintaining consistent temperatures throughout the entire building. This targeted approach can reduce heating costs by 20-30% in warehouses and retail spaces with varying occupancy patterns.
Poor insulation forces heating systems to work harder and consume more energy. Audit your building envelope for air leaks around windows, doors, and service penetrations. Weather stripping and door seals provide cost-effective improvements with immediate impact.
Install heavy curtains or blinds on windows to create additional insulation barriers. Close them during non-business hours to retain heat. For businesses with large glass facades, window films can reduce heat loss while maintaining natural light.
Cooling costs dominate summer energy bills for most Australian SMEs. Service air conditioning systems before temperatures rise. Clean condenser coils, replace filters, and check refrigerant levels to maintain peak efficiency.
Set cooling temperatures to 24-26°C during business hours. Staff comfort remains acceptable within this range while avoiding the exponential cost increases that occur with lower temperature settings. Use ceiling fans to create air circulation that allows comfortable conditions at higher thermostat settings.
Implement smart cooling schedules that pre-cool buildings during off-peak hours when electricity rates are lower. Energy cost reduction strategies often focus on shifting usage away from peak demand periods.
Reduce internal heat sources that force air conditioning systems to work harder. Replace incandescent lighting with LED alternatives, which produce significantly less heat while using 75% less energy. Schedule heat-generating activities like cooking or manufacturing processes during cooler morning hours when possible.
Install window coverings on east and west-facing windows to block direct sunlight during the hottest parts of the day. External awnings or shade structures provide more effective heat reduction than internal blinds.
Move non-essential energy usage away from peak demand periods. Charge equipment batteries, run dishwashers, and operate pool pumps during off-peak hours when electricity rates are lower. Our energy management services help businesses identify equipment that can be scheduled during lower-cost periods.
Install smart power strips and timers to automate load shifting for compatible equipment. This approach requires minimal staff training while delivering consistent results.
Battery storage systems allow businesses to store electricity during low-cost periods and use it during peak times. While the upfront investment is substantial, battery systems can reduce peak demand charges and provide backup power during outages.
Solar-plus-battery combinations work particularly well for businesses with daytime operations. Solar generation peaks during midday when cooling loads begin increasing, while batteries store excess production for later use during peak pricing periods.
Review your electricity contract and tariff structure before each seasonal peak period. Time-of-use tariffs can provide significant savings for businesses that can shift usage patterns, but they penalise high consumption during peak hours.
Demand tariffs charge based on your highest 30-minute usage period each month. Understanding when this peak occurs helps you implement strategies to reduce maximum demand. Even small reductions in peak usage can deliver substantial monthly savings.
Consider fixed-rate contracts that provide price certainty during volatile seasonal periods. While you might miss opportunities for lower prices during off-peak seasons, fixed rates protect against price spikes during high-demand periods.
Install energy monitoring systems that provide real-time usage data. Understanding your consumption patterns helps identify opportunities for improvement and tracks the effectiveness of seasonal strategies.
Set up alerts for unusual usage patterns or when consumption approaches peak demand thresholds. Early warning systems allow you to take corrective action before incurring higher charges.
Compare year-over-year usage during similar weather conditions to measure the impact of efficiency improvements. Weather-normalised comparisons provide more accurate assessments of your energy management progress.
Train staff on seasonal energy management practices. Simple actions like closing doors to conditioned spaces, adjusting blinds throughout the day, and reporting equipment malfunctions can significantly impact energy costs.
Create seasonal checklists for opening and closing procedures that include energy-related tasks. Consistency in daily operations helps maintain efficiency gains throughout peak seasons.
Seasonal energy management requires planning, consistent implementation, and ongoing monitoring. Our experienced energy professionals can help develop customised strategies that align with your business operations and budget constraints. Start preparing for seasonal peaks at least 6-8 weeks in advance to ensure systems are optimised and staff are trained on new procedures.
