The Peak Demand Reduction Scheme (PDRS) Rule sets out calculation methods for determining the number of peak reduction certificates that can be created from eligible activities.
There are 3 calculation methods for calculating peak demand reduction under the PDRS:
- Peak Demand Saving Method – installing more efficient equipment that uses less energy during peak times, for example installing a more efficient air conditioner to reduce electricity use on hot days
- Peak Demand Shifting Method – installing new systems, or changing the way existing systems are used, so that electricity consumption is shifted to an off-peak period. Examples include hot water systems and pool pumps timed to start after 10 pm
- Peak Demand Response Method – controlling certain technologies to temporarily reduce consumption during peak times, for example using smart pool pumps and interruptible industrial processes.
Sub-methods may be developed where needed.
Initially the scheme prioritises activities under the Peak Demand Saving method. The first sub-method in the PDRS Rule is the Reducing Demand Using Efficiency method, which saves energy during peak times by using energy more efficiently. Peak Demand Shifting and Peak Demand Response will be introduced in future PDRS Rules.
