PDRS Calculation methods

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.

The PDRS has 3 calculation methods, each with sub-methods, for calculating peak demand reduction:

• 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:
  — Reducing Demand Using Efficiency sub-method – reduces demand during peak times by using energy more efficiently, 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: 
  — Store and Shift Capacity sub-method – shifts energy use away from peak times by storing energy, for example installing a household battery
• Peak Demand Response Method – reduces demand during peak times by controlling certain technologies to temporarily reduce consumption:
  — Household Annual Demand Response sub-method – allows control of appliances during peak times, for example signing a battery up to a demand response contract.
